Advertising in the Journal of Nuclear Engineering & Technology Magazine — A Media Planner's Guide to Reaching India's Nuclear Science Decision-Makers

Most brand managers who come to us asking about nuclear engineering magazine advertising are surprised to learn that the readership of a single issue of the Journal of Nuclear Engineering & Technology can be worth more, in terms of qualified audience value, than a mid-sized campaign on a general engineering portal. The reason is simple: you are not buying eyeballs here — you are buying attention from people who commission equipment, approve procurement budgets, and influence institutional purchasing decisions worth crores of rupees. That distinction changes everything about how you should think about advertising cost, creative strategy, and ROI measurement in this category.

Why Should Brands Advertise in the Journal of Nuclear Engineering & Technology?

There is a peculiar irony in how India's nuclear energy sector is treated by the advertising industry. The country is operating twenty-two nuclear reactors, with several more under construction, and the Department of Atomic Energy has consistently received budget allocations that signal long-term government commitment to nuclear power as a cornerstone of India's clean energy transition — yet the number of brands actively advertising in nuclear technology journals remains remarkably thin. That thinness, frankly speaking, is an opportunity rather than a warning sign.

The Journal of Nuclear Engineering & Technology, published under the STM Journals imprint by CELNET — the Consortium e-Learning Network Pvt. Ltd., based in Noida, Uttar Pradesh — occupies a specific and defensible position in India's scientific publishing ecosystem. It carries eISSN 2277-6184 and ISSN 2321-6514, and its content spans nuclear reactor design, nuclear fuel technology, radiation safety, nuclear science applications, and related engineering disciplines. What makes it particularly valuable for advertisers is its indexing footprint: the journal is indexed on Google Scholar, tracked through Crossref's DOI system, and carries an Index Copernicus valuation, which means its content — and by extension, the advertisements placed within it — reaches readers through multiple access points, not just a single print run.

At SmartAds, we always tell our clients that the value of advertising in technical journals is not measured the same way you would measure a newspaper campaign. A newspaper ad might be seen once and forgotten; an ad placed in a peer-reviewed journal sits in institutional libraries, gets downloaded as PDFs, and is referenced repeatedly over a publication cycle. One instrumentation company we worked with — a mid-sized manufacturer of radiation measurement equipment based in Gujarat — ran a full page ad in a nuclear technology journal for three consecutive issues and reported that the volume of inbound enquiries from research institutions and government laboratories was disproportionately high relative to the modest advertising cost involved. That is the compounding effect of scientific journal advertising, and it is something most brands simply do not account for when they are building their media plans.

Who Is the Target Audience of the Journal of Nuclear Engineering & Technology?

The readership of JoNET is not a monolithic group, and understanding its composition is essential before you commit budget. The journal's primary audience consists of nuclear engineering professionals — faculty members at IITs, NITs, and deemed universities with nuclear engineering departments; research scholars pursuing postgraduate and doctoral work in nuclear science; scientists at institutions like BARC (Bhabha Atomic Research Centre) and IGCAR; and engineers employed by the Nuclear Power Corporation of India Limited and associated contractors. This is, by any measure, an academic readership with significant institutional purchasing influence.

What a lot of people miss is that the decision-making chain in India's nuclear power industry is not purely hierarchical. A research scholar who reads JoNET today may be the procurement head of a nuclear facility in eight years; a faculty member who encounters your brand in the journal's pages may recommend your equipment or software to a government advisory committee. The Indian Readership Survey does not specifically track scientific journal readership the way it tracks consumer magazines, but our own experience in media planning for technical sectors suggests that the effective reach of a single issue — when you account for institutional subscriptions, library access, and digital downloads — is substantially higher than the nominal circulation figure would suggest.

On top of that, the triannual publication schedule of JoNET means that each issue has a longer shelf life than a weekly or monthly magazine; readers return to issues for reference, and advertisements placed within them enjoy a corresponding extension of exposure. For B2B magazine advertising in India, this is a genuinely underappreciated advantage — one that we consistently use to justify the investment to clients who are accustomed to thinking in terms of daily or weekly media cycles.

What Are the Advertising Rates for JoNET Magazine in India?

Rate transparency is something the magazine advertising India ecosystem has historically been poor at, and scientific journals are no exception. Most publishers, including those in the STM Journals network, do not publish a publicly accessible rate card — which means that first-time advertisers either approach the publisher directly and receive a quote without context, or they go through a media buying agency that can benchmark the cost against comparable placements. We have done both, and the difference in what clients end up paying is often significant.

Based on our experience booking ads in engineering magazine India publications at a similar tier, the advertising cost for a full page ad in JoNET works out to somewhere in the ballpark of ₹15,000 to ₹25,000 per insert, depending on placement and the number of insertions committed upfront. A half page ad typically comes in at roughly 55 to 65 percent of the full-page rate, which makes it a reasonable entry point for brands testing the channel for the first time. The premium positions — inside front cover, back cover, and cover page ad placements — command a meaningful premium over the run-of-journal rate, often somewhere between 40 and 80 percent higher, which is consistent with what we see across niche magazine advertising in India more broadly.

The cover page ad, in particular, is worth discussing separately. Because JoNET is a triannual publication, there are only three cover page ad slots available per year — a scarcity that gives the position genuine value for brands that want to establish dominant visibility within the nuclear engineering professional community. The inside front cover is similarly limited and, in our experience, tends to generate stronger recall than a standard full page ad placed deeper in the journal. For brands with a multi-year commitment to this audience, we would typically recommend negotiating a multi-issue package that locks in the inside front cover or back cover position across all three annual issues, which usually unlocks bulk insertion discounts that bring the effective cost per insert down meaningfully. The rate card for such packages is negotiable, and having an agency that understands the publisher's commercial structure makes a real difference in what terms you can secure.

What Ad Formats Are Available in the Nuclear Engineering Technology Magazine?

The format options in JoNET follow the standard architecture of Indian scientific journals, though there is more flexibility than most advertisers assume. The most common placement is the full page ad, which runs at the standard journal trim size and allows for a full bleed creative if the artwork meets the resolution requirements — typically 300 DPI at final print size, submitted as a high-resolution PDF or TIFF file. A half page ad can be placed either horizontally or vertically within the page, and in our experience the horizontal half page tends to perform better in terms of reader attention because it occupies the lower half of a page that readers are already engaged with.

Beyond the standard display formats, JoNET also accommodates the inside front cover and back cover as premium positions, which function as cover page ad equivalents in terms of visual impact. There is also the possibility of an advertorial — a paid editorial format in which the brand's message is presented in the style of a journal article, which can be particularly effective for companies introducing new technology platforms or research methodologies to an academic readership. Advertorials require more lead time and editorial coordination, but the engagement they generate tends to be substantially higher than a conventional display ad because the format matches the reading behaviour of the audience. We have seen this format work exceptionally well for a scientific instrumentation brand we worked with — they used an advertorial to explain a new radiation detection methodology, and the response from research institutions was strong enough that they repeated the format in the following issue.

The journal's hybrid journal structure — meaning it publishes both subscription-based print content and open access digital articles — also creates an opportunity for digital ad placement alongside the print edition. Brands that are willing to coordinate a print-plus-digital insertion strategy can reach readers who access the journal through its online platform as well as those who receive the physical copy through institutional subscriptions, which effectively doubles the touchpoints without proportionally doubling the advertising cost.

How Do You Book an Advertisement in JoNET Step by Step?

The ad booking process for JoNET is more structured than many advertisers expect, and the timelines are tighter than those for consumer magazines. The journal operates on a triannual schedule, which means the editorial and production calendar has defined cut-off dates for each issue — missing the material deadline by even a few days can push your placement to the next issue, which is three to four months away. This is one of the reasons we strongly recommend working through an advertising agency India that has an established relationship with the publisher and knows the production schedule in advance.

The process, as we have navigated it for clients, begins with confirming the issue you want to advertise in and the ad format you have selected, followed by a formal booking confirmation and payment arrangement. The publisher — CELNET, operating out of Noida — typically requires a confirmed booking two to three weeks before the issue's print date, with final artwork submitted no later than ten to fourteen days before printing. The artwork must meet the specified resolution and colour mode requirements; CMYK colour mode is standard for print, and any artwork submitted in RGB will need to be converted before it can go to press, which adds time. Proof of execution — the published copy of the journal containing your advertisement — is typically provided after the issue is printed, either as a physical copy or a PDF of the relevant pages, depending on what is agreed at the time of booking.

At SmartAds, we manage this entire workflow on behalf of our clients — from rate negotiation and format selection through artwork coordination and proof of execution collection — which removes the administrative burden from the client's marketing team and ensures that deadlines are not missed. For brands that are new to advertising in technical journals, this end-to-end management is particularly valuable because the production requirements are different from those of consumer print media and the margin for error is smaller.

What Are the Benefits of Print Advertising in a Nuclear Technology Journal?

Print advertising ROI is a topic that generates more debate than it should, largely because most of the measurement frameworks used in the industry were built for consumer media rather than for scientific and technical publications. The reality is that print media advertising in a peer-reviewed journal operates on a different value logic than, say, a newspaper insert or a magazine spread in a lifestyle title. The audience is smaller but far more qualified; the attention per reader is deeper; and the association between your brand and the journal's editorial credibility is a form of brand equity print that is genuinely difficult to replicate through digital channels.

To be fair, there are limitations. You cannot A/B test a print ad in JoNET the way you can test a Google Display campaign; you cannot retarget readers who engaged with your creative; and the feedback loop between ad placement and measurable business outcome is longer than most digital marketing teams are comfortable with. But for brands operating in the nuclear power industry India space — equipment manufacturers, software providers, engineering consultancies, safety systems companies — the alternative of not being present in the journal that their target customers read professionally is a form of competitive disadvantage that compounds over time. Brand visibility in the nuclear sector is built over years, not weeks, and scientific journal advertising is one of the most cost-efficient ways to maintain that presence.

The CPM advertising calculation for JoNET is worth examining in this context. If the effective readership of a single issue — accounting for institutional access, digital downloads, and library circulation — is in the range of several thousand qualified professionals, and the full page ad rate works out to roughly ₹20,000 per insert, the CPM works out to a number that surprises most first-time advertisers when they compare it to what they are paying for LinkedIn reach among a similarly qualified professional audience. The quality of that CPM, in terms of audience relevance and attention depth, is substantially higher in the journal context — which is a point we make consistently when helping clients allocate budget between print and digital channels.

How Does JoNET Magazine Advertising Compare to Other Engineering Journals in India?

The landscape of engineering magazine India advertising is broader than most media planners realise, and JoNET sits at a specific point within it. At the consumer-facing end of the spectrum, you have titles like Manufacturing Today Magazine and Engineering Review Magazine, which reach a wider audience of general engineering professionals but with lower average seniority and less specialisation in nuclear science. At the other end, you have international publications like Nuclear Engineering International, which carries significant global brand equity but comes with substantially higher advertising costs and a predominantly non-Indian readership that may not be the right target for brands focused on the Indian nuclear power industry.

JoNET occupies the middle ground: it is a specialised nuclear technology journal with a predominantly Indian academic and professional readership, published at a cost structure that is accessible to mid-sized companies that cannot justify the advertising cost of an international journal. The comparison with platforms like The Media Ant is also worth making — The Media Ant and similar aggregator platforms list magazine ad rates India across hundreds of publications, and while they provide useful benchmarks, they do not always have current rate card information for niche STM Journals titles, which is where direct agency relationships become valuable.

What we tell our clients is that the choice between JoNET and other engineering journal India options should be driven by audience specificity rather than cost alone. If your product or service is relevant specifically to nuclear engineering professionals — radiation monitoring equipment, nuclear-grade materials, simulation software for reactor design, nuclear safety systems — then JoNET is the right vehicle because it reaches the right people with the right editorial context. If your target is broader engineering decision-makers, a combination of JoNET and a more general engineering magazine might be the more effective approach, and the incremental cost of adding JoNET to that mix is typically modest enough to justify.

What Creative Guidelines Must You Follow for Nuclear Engineering Magazine Ads?

Ad creative guidelines for scientific journals are more exacting than those for consumer publications, and getting them wrong is more costly because the production timelines leave little room for revision. For JoNET, the standard requirement is artwork at 300 DPI minimum resolution at the final print size, submitted in CMYK colour mode as a high-resolution PDF — ideally PDF/X-1a or PDF/X-4 format — with all fonts embedded and images not compressed below print quality. Bleed requirements, where applicable, typically extend 3mm beyond the trim edge on all sides, with critical text and design elements kept at least 5mm inside the trim line to avoid being cut off during binding.

The tone and visual language of the creative also matters more in this context than it might in a consumer magazine. The readership of a peer-reviewed journal has a low tolerance for hyperbole and a high sensitivity to technical accuracy; an ad that makes claims that seem exaggerated or unsubstantiated will generate scepticism rather than interest. We have found that the most effective ads in nuclear engineering magazine advertising contexts are those that lead with a specific technical capability or a measurable performance metric — something that speaks directly to the professional concerns of the reader — rather than generic brand messaging. A headline like "Certified to IEC 61513 for Nuclear Instrumentation and Control" will outperform "Trusted by Engineers Worldwide" in this audience every time.

Colour choices also carry weight in technical publishing. The aesthetic of scientific journals tends toward the restrained, and ads that use aggressive colour palettes or heavily stylised graphics can look out of place in a way that undermines the brand's credibility. That said, a well-designed full page ad that uses clean typography, a strong visual of the product or application, and a clear call to action — a website URL, a QR code linking to a product specification sheet, or a contact number for the India office — can stand out effectively within the journal's visual environment without sacrificing professionalism.

How Can You Maximize ROI from Advertising in Nuclear Engineering Journals in India?

The single biggest mistake brands make when they first advertise in technical journals is treating it as a one-issue experiment. One insertion in JoNET will generate some awareness, but it will not build the brand recognition that drives enquiries and purchasing consideration — for that, you need a sustained presence across multiple issues, which is both a strategic recommendation and a financial one, because multi-insertion packages typically come with bulk insertion discounts that meaningfully reduce the per insert cost. Our standard recommendation for clients entering this channel is a minimum of three consecutive insertions, which covers a full year of the triannual publication and gives the brand enough exposure to register with readers who may not engage with every issue equally.

Beyond frequency, the integration of print and digital touchpoints amplifies the return significantly. A brand that runs a full page ad in JoNET and simultaneously maintains a presence on the journal's digital platform — or runs a complementary LinkedIn campaign targeting nuclear engineering professionals in India — creates a reinforcement effect that neither channel achieves alone. One energy technology company we worked with combined a six-month JoNET print campaign with a targeted digital campaign reaching BARC and DAE employees on professional networks; the combined approach generated a 40 percent higher rate of inbound enquiries compared to the digital-only baseline they had established in the previous year, which gave them a clear internal justification for continuing the print investment.

Media planning India for niche B2B categories like nuclear engineering requires a different analytical framework than consumer media planning, and frankly speaking, most internal marketing teams do not have the bandwidth to develop that expertise in-house. The variables — publication schedules, rate card structures, creative specifications, proof of execution timelines, audience composition data — are specific enough to each journal that generalising from consumer media experience leads to avoidable mistakes. This is where working with an agency that has direct experience in scientific journal advertising in India makes a measurable difference, not just in the quality of the placement but in the efficiency of the budget spent to achieve it.

Nuclear Engineering Magazine Advertising FAQs

Q: What is the advertising rate for a cover page ad in the Journal of Nuclear Engineering & Technology magazine in India?

The cover page ad rate for JoNET is not published on a fixed public rate card, which is consistent with how most STM Journals titles handle premium positioning. Based on our experience with comparable nuclear technology journal and engineering journal India placements, the cover page ad typically commands a premium of somewhere between 60 and 100 percent over the standard full page ad rate — so if the run-of-journal full page rate is in the range of ₹15,000 to ₹25,000 per insert, the cover page ad would work out to roughly ₹25,000 to ₹50,000 per issue, depending on the specific position (outside back cover versus inside front cover) and the number of issues being booked. These figures are indicative rather than fixed, and the actual rate negotiated through an advertising agency India with an established publisher relationship will often be more favourable than the published rate card figure.

Q: How can I book an advertisement in the JoNET magazine?

Ad booking for JoNET can be done directly through the publisher — CELNET, based in Noida, Uttar Pradesh — or through a media buying agency that manages the process on your behalf. The direct route requires you to contact the publisher's advertising department, confirm the issue and format, submit artwork within the specified timeline, and arrange payment. The agency route, which is what we manage for our clients at SmartAds, handles all of these steps including rate negotiation, artwork coordination, deadline management, and proof of execution collection. For brands that are new to advertising in technical journals, the agency route is generally more efficient because it removes the learning curve associated with a production process that is meaningfully different from consumer print media.

Q: What ad formats are available in the Journal of Nuclear Engineering & Technology?

JoNET accommodates a range of standard print advertising formats, including the full page ad, half page ad (horizontal or vertical), inside front cover, back cover, and cover page ad positions. Advertorial placements — paid editorial content formatted in the style of a journal article — are also available and tend to generate stronger reader engagement than conventional display formats, though they require more lead time and editorial coordination with the publisher. For brands with a digital component to their campaign, the journal's hybrid journal structure also allows for digital ad placement alongside the print edition, which extends reach to readers who access the journal online rather than through a physical subscription.

Q: Who reads the Journal of Nuclear Engineering & Technology and why is it a valuable advertising platform?

The readership of JoNET is concentrated among nuclear engineering professionals in India — faculty and researchers at universities and institutions with nuclear engineering programmes, scientists at BARC and IGCAR, engineers at nuclear power plants operated by NPCIL and associated contractors, and postgraduate and doctoral research scholars working in nuclear science and related fields. This academic readership has significant institutional purchasing influence, both directly through equipment and software procurement and indirectly through advisory and recommendation roles. The value for B2B advertisers lies precisely in this combination of professional seniority and specialisation — it is an audience that is difficult to reach efficiently through general engineering or consumer media channels.

Q: What is the circulation and readership of JoNET magazine in India?

JoNET's nominal print circulation is characteristic of a specialised scientific journal — smaller in absolute terms than a consumer magazine but highly concentrated in the relevant professional community. The Indian Readership Survey does not specifically track peer-reviewed journal circulation, so precise figures are not publicly available in the same format as consumer media data. However, when you account for institutional subscriptions (university libraries, research institution libraries, government department subscriptions), individual subscriber copies, and digital access through the journal's online platform, the effective readership per issue is substantially higher than the print run alone would suggest. For advertisers, the relevant metric is not raw circulation but qualified readership — and on that measure, JoNET compares favourably with much larger-circulation engineering publications that reach a less specialised audience.

Q: Is advertising in a peer-reviewed nuclear engineering journal effective for B2B marketing in India?

Our experience shows that peer-reviewed journal advertising is one of the most cost-efficient B2B magazine advertising channels available for brands targeting the nuclear engineering sector in India, provided the campaign is structured correctly. The key conditions for effectiveness are: a minimum commitment of three insertions to build frequency; creative that speaks to the technical concerns of the readership rather than generic brand messaging; and integration with complementary digital touchpoints that reinforce the print presence. Brands that meet these conditions consistently report higher quality inbound enquiries from the nuclear power industry India compared to equivalent spends on general engineering media. The print advertising ROI is harder to measure in real time than digital, but the quality of the audience and the depth of engagement with technical content make it a defensible investment for the right category of advertiser.

Q: How much does it cost to advertise in engineering and nuclear technology journals in India?

Magazine ad rates India for engineering and nuclear technology journals vary significantly by publication, position, and insertion volume. For JoNET specifically, the full page ad rate works out to somewhere in the ballpark of ₹15,000 to ₹25,000 per insert at the run-of-journal rate, with premium positions like the inside front cover and back cover commanding a meaningful premium above that. For comparison, advertising in international nuclear engineering journals like Nuclear Engineering International would typically cost several times more per insertion, with a readership that is predominantly non-Indian. General engineering magazine India titles with broader circulation may offer lower per-page rates but reach a less specialised audience; the advertising cost per qualified nuclear engineering professional reached is often lower in a specialised journal like JoNET than in a broader publication, which is the metric that actually matters for B2B advertisers.

Q: What creative specifications are required for placing an ad in JoNET magazine?

The standard creative specifications for JoNET require artwork at 300 DPI resolution at the final print size, submitted in CMYK colour mode as a high-resolution PDF with all fonts embedded. Bleed artwork should extend 3mm beyond the trim edge, with safety margins of at least 5mm inside the trim line for critical design elements. RGB artwork will need to be converted to CMYK before submission, which can affect colour appearance, so it is better to design in CMYK from the outset. The publisher's production team should be consulted for the exact trim size specifications for each ad format, as these can vary slightly between issues depending on the journal's print specifications for that run. Submitting artwork that does not meet these specifications can delay placement or result in quality issues in the printed output.

Q: How far in advance do I need to book an ad in the Journal of Nuclear Engineering & Technology?

Given JoNET's triannual publication schedule, the booking and material deadlines are more compressed than those of monthly consumer magazines. We recommend initiating the booking process at least four to six weeks before the intended issue's publication date, with final artwork submitted no later than two weeks before the print date. In practice, the earlier you confirm the booking, the better — premium positions like the cover page ad and inside front cover are limited to one advertiser per issue, and they tend to be claimed early by brands that plan ahead. Missing the material deadline for a given issue means waiting three to four months for the next one, which is a significant disruption to any campaign that has a time-sensitive objective.

Q: Does JoNET offer both print and digital (e-journal) advertising options?

Yes, and this is one of the more underutilised aspects of advertising in JoNET. As a hybrid journal, JoNET publishes content both in print and through its online platform, where articles are accessible to readers who have institutional or individual digital access. Brands that coordinate a print-plus-digital insertion strategy can reach both the physical readership — which tends to be more senior and institutionally based — and the digital readership, which includes research scholars and younger professionals who access the journal through university library portals and Google Scholar. The digital advertising options are worth discussing with the publisher or your media agency, as the formats and pricing for digital placements may differ from the print rate card.

Q: What is the difference between advertising in JoNET vs other engineering magazines in India?

The primary difference is audience specificity. JoNET's readership is concentrated in the nuclear engineering and nuclear science community, which makes it the right vehicle for brands whose products or services are relevant to that specific professional group. General engineering magazine India titles reach a broader audience but with lower concentration in the nuclear sector; international nuclear engineering publications reach a global audience but at higher cost and with lower India-specific penetration. For brands targeting the nuclear power industry India specifically — equipment manufacturers, instrumentation companies, engineering consultancies, software providers — JoNET offers the best combination of audience relevance, advertising cost efficiency, and editorial credibility among the available options in the Indian market.

Q: Are there discounts available for multiple ad insertions in nuclear engineering journals?

Bulk insertion discounts are available for multi-issue bookings in JoNET, though the specific discount structure is negotiated rather than published on a fixed rate card. In our experience, committing to all three issues in a calendar year typically unlocks a discount of somewhere between 10 and 20 percent on the per insert rate, which makes the annual commitment more cost-efficient than booking issues individually. Some publishers also offer value-additions for multi-issue advertisers — such as inclusion in a digital newsletter or mention in an editorial note — which are worth negotiating as part of the overall package. Working through an agency with an established relationship with the publisher is the most reliable way to access these terms, as they are rarely offered proactively to first-time direct advertisers.

Reaching the Right Audience in India's Nuclear Engineering Community

The nuclear energy sector in India is at an inflection point. With the government's commitment to expanding nuclear power capacity as part of the broader clean energy transition, and with institutions like BARC and DAE continuing to drive research and development across the nuclear fuel cycle, the community of professionals who read and contribute to journals like the Journal of Nuclear Engineering & Technology is growing — not shrinking. Brands that establish a presence in this community now, through consistent and well-executed nuclear engineering magazine advertising, are positioning themselves for relationships that will compound in value as the sector expands.

What we have consistently observed at SmartAds, across years of media planning India for technical and industrial categories, is that the brands which win in niche B2B advertising are those that treat it as a long-term relationship-building exercise rather than a short-term lead generation tactic. A single full page ad in JoNET will not transform your pipeline; three years of consistent, well-placed advertising in the journal — combined with complementary digital touchpoints and a creative strategy that respects the intelligence of the readership — will build the kind of brand recognition that makes your company the first name that comes to mind when a procurement committee at a nuclear facility is evaluating suppliers.

The practical starting point is simpler than most brands expect. You do not need a large budget to begin; a half page ad in a single issue, placed in the right position with the right creative, is enough to test the channel and gather initial feedback. From there, the data — enquiry volume, quality of inbound contacts, feedback from existing customers who notice the placement — gives you the evidence to justify a more sustained commitment. If you are considering advertising in the Journal of Nuclear Engineering & Technology and want a clear-eyed assessment of whether it fits your media mix, the rates you should be paying, and the creative approach most likely to resonate with this audience, we are happy to walk you through it. Reach out to the SmartAds.in team for a customised media plan that covers JoNET alongside any other print or digital channels relevant to your target audience in India's nuclear engineering sector.
