Rapid hazard assessment of volcanic ballistic projectiles using long-exposure photographs: insights from the 2010 eruptions at Tungurahua volcano, Ecuador
Authors: Bernard Benjamin
Published: June 2018

Assessing hazard associated to volcanic ballistic projectiles is essential to limit fatal incidents close to erupting vents. Current state-of-the-art methods using high-speed visual and thermal images and volcanic radars permit to obtain high resolution information during explosive events but are limited to few laboratory volcanoes. Nowadays, long-exposure photographs at erupting volcanoes have become common and can be used to obtain meaningful information. In this paper I present a method to extract volcano-physical data from the projectile parabolic trajectory after adequate scaling and projection. The results, obtained from the analysis of 28 photographs from three eruptive phase at Tungurahua volcano in 2010, allowed to constrain the geometry of the vent (20 m-diameter for the upper conduit and 70 m-diameter inner crater), the diameter of the ballistic projectiles (up to 4.3 m), their launching angle (50 to 90°), their minimum launching velocity (40 to 145 m.s-1), and their maximum distance reach (up to 1330 m from the vent). This turnkey method can help to characterize eruptive dynamics as well as to perform rapid hazard assessment at dangerously explosive erupting volcanoes.

Authors: Usup Djamila
Published: June 2018

Kedudukan perempuan dalam pandangan ajaran Islam tidak sebagaimana diduga atau dipraktikkan masyarakat, banyak yang salah tafsir atau bahkan masih terus memperdebatkan teks-teks terkait dengan bagaimana kedudukan perempuan di dalam Islam. Salah satu hambatan berat untuk mewujudkan keadilan hak-hak perempuan dan laki-laki adalah mapannya streotip-streotip yang kurang bersahabat dengan perempuan. Beragam prasangka itu selama puluhan tahun sudah membeku ke dalam teks-teks keagamaan akibat penafsiran yang bias gender dan berideologi patrhiarki. Padahal Islam memposisikan perempuan secara proporsional sesuai dengan kodratnya sebagai perempuan. Tulisan ini akan membahas tentang bagaimana kedudukan perempuan di dalam Islam dengan pendekatan normatif-teologis. Penelitian ini menggunakan jenis penelitan literatur yaitu pengumpulan data yang diperoleh dari pustaka yang berhubungan dengan wilayah yang diteliti. Hasil dari penelitian ini adalah didapatkan kesimpulan bahwa Islam begitu sangat melindungi perempuan. Islam mensejajarkan kedudukan antara perempuan dan Islam, perempuan juga berhak mendapatkan pendidikan, berhak bekerja di luar rumah dan berhak aktif dalam memangku jabatan politik.
SEJARAH USHUL FIQH MASUK DI INDONESIA
Authors: Rahmawati Rahmawati
Published: June 2018

Sejak periode awal sejarah Islam, perilaku kehidupan kaum muslimin dalam keseluruhan aspeknya telah diatur oleh hukum Islam. Aturan-aturan ini, pada esensinya, bersifat religius. Oleh karena itu, dalam pembinaan dan pengembangannya, selalu diupayakan berdasarkan kepada al-Qur’an, sebagai wahyu Illahi yang terakhir, yang pengaplikasiannya untuk sebagian besar dicontohkan dan dioperasionalkan oleh sunnah Rasulullah saw. Dalam perkembangan selanjutnya, Islam yang sudah menyebar sedemikian luasnya, pluralitas masyarakat tidak dapat dihindarkan lagi, masalah yang timbul pun tidak kalah kom­pleksnya yang menuntut upaya ijtihad yang lebih komprehensip bagi segenap pengikutnya, khususnya para intelektual muslim yang memiliki tanggung jawab yang paling berkompeten dalam hal tersebut. Hal demikian dilakukan untuk lebih mengaktuali­sasikan misi Islam yang bersifat elastis dan tidak ada unsur pemaksaan bagi manusia.Dalam tulisan ini akan dipaparkan masalah awal penyu­sunan ilmu ushul fiqh (dan kemudian menjadi salah satu dari bagian displin ilmu) yang telah dipelopori Imam Syafi’i dalam menyusun ilmu tersebut secara sistematis, yang dengan kecerdasannya, ia mampu menangkap fenomena yang ada dari per­kembangan ilmu ushul fiqh dari periode sebelumnya dan diapli­kasikan dalam karyanya yang konkrit.

Earth Block Construction in Nepal as Alternative to Reconstruction after the 2015 Gorkha Earthquake
Authors: Kasajoo Aayush , Hongwang Ma
Published: June 2018

On April 25, 2015, 7.8 magnitude earthquake occurred in Central Nepal with epicentre in Gorkha District at 11:56 NST (local time). A major aftershock of magnitude 7.3 on May 12, 2015 resulted in enhancement of damages. Almost 800,000 buildings were fully or partially damaged. This paper highlights the different types of buildings in Nepal and the damage patterns recorded from the earthquake. Different causes of failures are highlighted for different types of building including masonry, wooden, reinforced cement concrete etc. 44.2% of the buildings in Nepal are masonry type which in fact performed the worst during the earthquake. One of the main reason was the poor quality of bricks used in the buildings. Most of the masonry buildings in Nepal are located in the rural areas where the economic condition of people are not up to the level. Utilization of local resources and people skill is important. Thus, as an alternative to it, we have put forward the idea of earth block construction which is not only earthquake resillient but lighter, greener sustainable and economical. Journal of the Institute of Engineering, 2018, 14(1): 64-74

One-Dimensional Creativity: A Marcusean Critique of Work and Play in the Video Game Industry
Authors: Bulut Ergin
Published: June 2018

Creativity is at the heart of the video game industry. Industry professionals, especially those producing blockbuster games for the triple-A market, speak fondly of their creative labour practices, flexible work schedules, and playful workplaces. However, a cursory glance at major triple-A franchises reveals the persistence of sequel game production and a homogeneity in genres and narratives. Herbert Marcuse’s critique of one-dimensionality may help to account for this discrepancy between the workers’ creative aspirations and the dominant homogeneity in game aesthetics. What I call ‘one-dimensional creativity’ defines the essence of triple-A game production. In the name of extolling the pleasure principle at work, one-dimensional creativity eliminates the reality principle, but only superficially. One-dimensional creativity gives game developers the opportunity to express themselves, but it is still framed by a particular technological rationality that prioritises profits over experimental art. One-dimensional creativity negates potential forms of creativity that might emerge outside the industry’s hit-driven logics. Conceptually, ‘one-dimensional creativity’ renders visible the instrumentalisation of play and the conservative design principles of triple-A game production – a production that is heavily structured with technological performance, better graphics, interactivity, and speed. Multi-dimensional video game production and aesthetics, the opposite of one-dimensional creativity, is emerging from the DIY game production scene, which is more invested in game narratives and aesthetics outside the dominant logics of one-dimensionality in triple-A game production.

Impact of ENSO on extreme temperatures in Vietnam
Authors:   Centre for Hydro-Meteorological and Environmental Sciences and Technologies, Nguyen Duc Ngu
Published: June 2018

This paper presents the results of research on the effects of ENSO to extreme temperature in Vietnam [1] through the frequency deviation of the occurrence extreme temperatures during ENSO and non-ENSO seasons. The results demonstrate that in an El Niño winter, the frequency of absolute maximum temperature decreased over mountainous areas of the temperature in comparison to those under the influence of a non-ENSO winter. In summer, the effects of El Niño and La Nina generally led to a reduction in the frequency of maximum temperatures in comparison to the non-ENSO condition. For minimum temperatures, the effect of El Niño winter led to a decrease in the appearance of the temperatures, while the effect of La Nina led to an increase in the appearance of this characteristic. In contrast, the effects of El Niño and La Nina led to a reduction in the frequency of minimum temperatures during summer. Generally, in both El Niño and La Nina conditions, significant changes were observed in the distribution of frequency deviation with regard to both patterns and values of seasons, in which the South obviously exhibited more changes than the North.

Authors: Bauer Gregory , Pasricha Gurnain , Sekkel Rodrigo , Terajima Yaz
Published: June 2018

This article analyzes the implications of the global financial cycle for conventional and unconventional monetary policies and macroprudential policy in small, open economies such as Canada's. The article starts by summarizing recent work on global financial cycles. These cycles cause time variation in global risk premia, which affects the transmission mechanisms of both conventional and unconventional monetary policies in small, open economies. The article then summarizes new work showing that the central banks' leaning against the effects of the global financial cycle would typically be too costly. The article concludes with some suggestions for the formation of macroprudential policies.
An experimental and numerical investigation of the effects of geometry and spot welds on the crashworthiness of vehicle thin-walled structures
Authors: Demirci Emre , Yıldız Ali Rıza
Published: June 2018

This paper aims to develop a new crash box with improved crashworthiness at reduced cost and weight as a base design for use in the automotive industry. Firstly, a baseline crash box model as presently used by the automotive industry was comprehensively examined by numerical crash analysis using Ls-Dyna software. Considering the initial design geometry, forty-five different crash box designs were developed by making changes in the geometry and wall thickness of the thin walled structures. The effects of the changes in wall thickness and geometry in alternative crash box designs on crash performances such as total energy absorption, peak crush force, mean crush force, specific energy absorption and crush force efficiency were investigated. The optimum crash box design obtained numerically was validated experimentally by means of the drop tower impact system. The numerical crash analysis results clearly agree with the experimental test results. In this study, a new crash box design at a lower cost and performing better in crashes compared with the other forty-six designs has been obtained and can be used in the automotive industry as an energy absorber. The results have revealed that crash box geometry, as well as the number and position of the spot welds and sheet-metal thickness have an important effect on crash performance, weight and cost of the crash boxes.

Authors: Zhang Yaguang , Fu Hanguang , Lin Jian , Lei Yongping , Ma Shengqiang
Published: June 2018

In this paper, the effects of different quenching temperatures on the microstructure, hardness, and wear resistance of modified Al-bearing high boron high speed steel were investigated by means of optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD), a hardness tester, and an MM-200 block-on-ring wear testing machine. The results showed that the as-cast microstructure of modified Al-bearing high boron high speed steel consisted of martensite, ferrite, pearlite and continuous network eutectic borocarbides which were distributed at the grain boundary. The eutectic borocarbides mainly included M2B and M7(C, B)3. With an increase of quenching temperature, the matrix turned into martensite, and the continuous network structure of eutectic borocarbides were gradually broken and changed to the spherical; the secondary borocarbides M23(C, B)6 were precipitated from the matrix. After quenching at 1150 °C, eutectic borocarbides were clearly visible as a broken network and spheroidal in shape, and the distribution was more uniform. When the quenching temperature was in a range of 1000 °C to 1150 °C, the hardness and wear resistance of the alloy obviously increased. When the quenching temperature attained 1150 °C, hardness reached the highest 64.3 HRC, and the wear resistance was best.

Authors: Ekşi Seçil , Genel Kenan , Kaptı Akın Oğuz , Acar Kenan
Published: June 2018

In this study, the bending behavior of a thin-walled aluminum square tube (AST) were analyzed using the finite element (FE) method, and reinforcing arrangements were decided for the composite beams based on the FE results. Accordingly, bending behavior of thin-walled ASTs with internal cast polyamide (PA6) and external glass fiber reinforcement polymers (GFRP) were investigated via a quasi static three-point bending test experimentally. Moreover, bending performance under impact loading was also investigated experimentally. The results revealed that local buckling has a decisive influence on bending performance of the tube, and the contribution of inner reinforcement is more effective than outer reinforcement. The reinforcements provide 575 % and 312 % increases in bending load and impact energy, respectively. The developed plastic-metal hybrid-composite structure is promising especially for critical supporting parts in vehicles. It is thought that the combination of these materials will offer new focus of attention for designers seeking more appropriate composite beams with high bending load and impact resistance.

Published: June 2018

Justice that has not existed and is apparent among the disabilities in Indonesia is very large and spread in the archipelago is very large, making the issue of equality is a very important thing especially with the publication of the Disability Act No. 8 of 2016 at the beginning of that year. Only a few provinces that understand properly and well on open and potential issues and issues will affect other areas including the increasingly growing number of elderly people in Indonesia due to the increasing welfare of the people. The government of DKI Jakarta, including the most concerned with disability, from the beginning has set a bold step to defend things related to disability, including local governments in Solo, Bali, Makassar and several other areas. Leprosy belonging to the disability community has a very tough marginalization, the disability that arises from leprosy quite a lot, reaches ten percent more and covers the poor areas of Indonesia, such as Nusa Tenggara Timur, Papua, South Sulawesi Provinces and even East Java and West Java and Central Java Provinces. If we compare again with the ASEAN countries we also do not miss the moment in ratifying the CRPD (Convention of Rights for People with Disability) into the Law of Disability No. 8 of 2016 which, although already published but still get rejections in some sections because do not provide proper empowerment and rights equality. The struggle is long and must be continued to build equal rights in all areas, not only health and welfare but also in the right of the right to receive continuous inclusive education.

Published: June 2018

Histone deacetylase 6 (HDAC6) is currently being discussed as a promising therapeutic target for the treatment of Alzheimer's disease (AD). Mounting evidence indicates that increased HDAC6 expression may contribute to AD-associated neurodegeneration, although beneficial effects have also been identified. In the present study, we tested the potential of two selective HDAC6 inhibitors, tubastatin A and ACY-1215, to rescue cognitive deficits in a mouse model of AD. We found that both tubastatin A and ACY-1215 alleviated behavioral deficits, altered amyloid-β (Aβ) load, and reduced tau hyperphosphorylation in AD mice without obvious adverse effects. Our data suggested that tubastatin A and ACY-1215 not only promoted tubulin acetylation, but also reduced production and facilitated autophagic clearance of Aβ and hyperphosphorylated tau. Further, the decreased hyperphosphorylated tau and increased tubulin acetylation may account for the improved microtubule stability in AD mice after tubastatin A/ACY-1215 treatment. These preclinical results support the detrimental role of HDAC6 in AD, and offer prospective approaches for using tubastatin A/ACY-1215 as potential therapeutic strategy for AD.
30-days’ outcome of haemorrhagic stroke: correlation between intracerebral hemorrhage score and modified Rankin score

Published: June 2018

Intracerebral hemorrhage (ICH) constitutes 10% to 15% of all strokes. Within 30 days reported mortality is 35-52% and only 20% is functionally independent in 6 months. Despite several existing outcome prediction models for ICH, modified Rankin scale is found to be best predictor of outcome in early and long term period. To find out 30-day mortality in ICH and predict outcome based on modified Rankin score. In this study, 48 patients presenting with acute ICH presenting to a tertiary hospital in Khulna were enrolled. The 30-day mortality and disability were recorded, and ICH score along with modified Rankin score at presentation were calculated. In this study, the 30-day mortality rate was 27.1%; regression analysis showed the correlation between the scores (as measured by modified Rankin scale) for patient disability, intraventricular hemorrhage, the Glasgow Coma score, and volume of hematoma (>30 ml vs <30 ml) were significantly correlated with corresponding ICH scores. The ICH scale is a simple clinical grading scale which can predict mortality as well as disability in haemorrhagic stroke within 30 days that can be helpful to physicians in prioritization of their patient management and forecasting about prognosis.Mediscope Vol. 5, No. 1: Jan 2018, Page 10-14
Genetic Engineering of Energy Crops to Reduce Recalcitrance and Enhance Biomass Digestibility
Authors: Yadav Monika , Paritosh Kunwar , Chawade Aakash , Pareek Nidhi , Vivekanand Vivekanand
Published: June 2018

Bioenergy, biofuels, and a range of valuable chemicals may be extracted from the abundantly available lignocellulosic biomass. To reduce the recalcitrance imposed by the complex cell wall structure, genetic engineering has been proposed over the years as a suitable solution to modify the genes, thereby, controlling the overall phenotypic expression. The present review provides a brief description of the plant cell wall structure and its compositional array i.e., lignin, cellulose, hemicellulose, wall proteins, and pectin, along with their effect on biomass digestibility. Also, this review discusses the potential to increase biomass by gene modification. Furthermore, the review highlights the potential genes associated with the regulation of cell wall structure, which can be targeted for achieving energy crops with desired phenotypes. These genetic approaches provide a robust and assured method to bring about the desired modifications in cell wall structure, composition, and characteristics. Ultimately, these genetic modifications pave the way for achieving enhanced biomass yield and enzymatic digestibility of energy crops, which is crucial for maximizing the outcomes of energy crop breeding and biorefinery applications.

Published: June 2018

Bioethanol production in the midwestern U.S. has largely focused on maize (Zea mays L.) grain for starch-based ethanol production. There has been growing interest in lignocellulosic biomass as a feedstock for biofuels. Because maize adapted to the tropics does not initiate senescence as early as temperate-adapted maize, using a tropical germplasm could improve biomass yield. This study compares the suitability of temperate and tropical maize with differing relative maturities as feedstocks for bioethanol production. Field trials were established in central Iowa during the 2014 and 2015 growing seasons. Six hybrids of different relative maturities were grown at two levels of N fertilization and two row spacings to evaluate total biomass production and feedstock quality under midwestern U.S. conditions. Total biomass, height at the final leaf collar, stem diameter at one meter above ground, and lignocellulose concentration were measured at harvest. Tropical maize was taller and had greater non-grain and total biomass production (15% more than temperate maize), while temperate maize had greater grain yield and grain starch, as well as earlier maturation. Narrower row spacing had greater biomass and grain yield. Nitrogen fertilization rate affected grain and feedstock composition. Tropical maize had lower cellulose, lignin, and ash concentrations and higher nitrogen at harvest than that of temperate maize. Conversely, temperate maize had greater ash, cellulose, and lignin concentrations. Tropical maize planted at high densities has high potential as a feedstock for bioethanol production in the U.S. Midwest.

Although the policy-gradient methods for reinforcement learning have shown significant improvement in image captioning, how to achieve high performance during the reinforcement optimizing process is still not a simple task. There are at least two difficulties: (1) The large size of vocabulary leads to a large action space, which makes it difficult for the model to accurately predict the current word. (2) The large variance of gradient estimation in reinforcement learning usually causes severe instabilities in the training process. In this paper, we propose two innovations to boost the performance of self-critical sequence training (SCST). First, we modify the standard long short-term memory (LSTM)based decoder by introducing a gate function to reduce the search scope of the vocabulary for any given image, which is termed the word gate decoder. Second, instead of only considering current maximum actions greedily, we propose a stabilized gradient estimation method whose gradient variance is controlled by the difference between the sampling reward from the current model and the expectation of the historical reward. We conducted extensive experiments, and results showed that our method could accelerate the training process and increase the prediction accuracy. Our method was validated on MS COCO datasets and yielded state-of-the-art performance.

Published: June 2018

To better understand the fire risk of nitrocellulose (NC) used for the civil industry, the combustion properties of NC-alcohol humectant (isopropanol and ethanol) and -plasticizer (dibutyl phthalate) mixtures were investigated experimentally in this work. Flames with considerable sparks were observed for nitrocellulose-humectant samples, while the nitrocellulose-plasticizer mixture exhibited extremely bright flames without obvious sparks. The flame heights for all the samples were determined from the video record. According to the fundamentals of fire phenomena, a simplified model to predict the heat release rates of current NC samples was developed based on the flame height data. By combining the experiment results by ISO 5660 and stoichiometric equations, the critical parameter H c / r is recalculated as 3251, 3228, and 3201 kJ/kg for NC-I, NC-E, and NC-D samples, respectively. Ultimately, the heat release rates predicted by the modified model coincided well with that measured by ISO 5660.

Several depth image-based rendering (DIBR) watermarking methods have been proposed, but they have various drawbacks, such as non-blindness, low imperceptibility and vulnerability to signal or geometric distortion. This paper proposes a template-based DIBR watermarking method that overcomes the drawbacks of previous methods. The proposed method exploits two properties to resist DIBR attacks: the pixel is only moved horizontally by DIBR, and the smaller block is not distorted by DIBR. The one-dimensional (1D) discrete cosine transform (DCT) and curvelet domains are adopted to utilize these two properties. A template is inserted in the curvelet domain to restore the synchronization error caused by geometric distortion. A watermark is inserted in the 1D DCT domain to insert and detect a message from the DIBR image. Experimental results of the proposed method show high imperceptibility and robustness to various attacks, such as signal and geometric distortions. The proposed method is also robust to DIBR distortion and DIBR configuration adjustment, such as depth image preprocessing and baseline distance adjustment.

Published: June 2018

Recently, the use of internet has become widespread, increasing the use of mobile phones, tablets, computers, Internet of Things (IoT) devices and other digital sources. In the health sector with the help of new generation digital medical equipment, this digital world also has tended to grow in an unpredictable way in that it has nearly 10% of the global wide data itself and continues to keep grow beyond what the other sectors have. This progress has greatly enlarged the amount of produced data which cannot be resolved with conventional methods. In this work, an efficient model for the storage of medical images using a distributed file system structure has been developed. With this work, a robust, available, scalable, and serverless solution structure has been produced, especially for storing large amounts of data in the medical field. Furthermore, the security level of the system is extreme by use of static Internet protocol (IP), user credentials, and synchronously encrypted file contents. One of the most important key features of the system is high performance and easy scalability. In this way, the system can work with fewer hardware elements and be more robust than others that use name node architecture. According to the test results, it is seen that the performance of the designed system is better than 97% from a Not Only Structured Query Language (NoSQL) system, 80% from a relational database management system (RDBMS), and 74% from an operating system (OS).

Published: June 2018

Unbalance vibration is one of the main vibration forms of a high speed machine tool spindle. The overlarge unbalance vibration will have some adverse effects on the working life of the spindle system and the surface quality of the work-piece. In order to reduce the unbalance of a high speed spindle system, a pneumatic online dynamic balance device and its control system are presented in the paper. To improve the balance accuracy and adaptation of the balance system, the gain parameter adaption and scheduling control method are proposed first, and then the different balance effects of the influence coefficient method and the gain scheduling control method are compared through many dynamic balance experiments of the high speed spindle. The experimental results indicate that the gain parameters can be changed timely according to the transformation of the speed and kinetic parameters of the spindle system. The balance accuracy can be improved for a high speed spindle with time-varying characteristics, based on the adaptive gain scheduling control method.

Published: June 2018

In the developed world, underground facilities are increasing day-by-day, as it is considered as an improved utilization of available space in smart cities. Typical facilities include underground railway lines, electricity lines, parking lots, water supply systems, sewerage network, etc. Besides its utility, these facilities also pose serious threats to citizens and property. To preempt accidental loss of precious human lives and properties, a real time monitoring system is highly desirable for conducting risk assessment on continuous basis and timely report any abnormality before its too late. In this paper, we present an analytical formulation to model system behavior for risk analysis and assessment based on various risk contributing factors. Based on proposed analytical model, we have evaluated three approximation techniques for computing final risk index: (a) simple linear approximation based on multiple linear regression analysis; (b) hierarchical fuzzy logic based technique in which related risk factors are combined in a tree like structure; and (c) hybrid approximation approach which is a combination of (a) and (b). Experimental results shows that simple linear approximation fails to accurately estimate final risk index as compared to hierarchical fuzzy logic based system which shows that the latter provides an efficient method for monitoring and forecasting critical issues in the underground facilities and may assist in maintenance efficiency as well. Estimation results based on hybrid approach fails to accurately estimate final risk index. However, hybrid scheme reveals some interesting and detailed information by performing automatic clustering based on location risk index.

Compound K, a major metabolite of ginsenosides Rb1, which is produced by human intestinal bacteria after oral administration, is one of the main pharmacologic compounds found in ginseng. In our previous study, we demonstrated that compound K inhibited the production of nitric oxide (NO) and prostaglandin E2 in lipopolysaccharide (LPS)-treated RAW264.7 cells. However, the mechanisms by which compound K may be effective against inflammation remain unknown. In the present study, compound K significantly inhibited LPS-induced NO production by suppression of inducible NO synthase (iNOS) in LPS-treated RAW264.7 cells. Compound K also inhibited LPS-induced cyclooxygenase-2 (COX-2) expression at both the mRNA and protein levels. It effectively suppressed both the release and mRNA expression levels of pro-inflammatory cytokines such as interleukin-1β (IL-1β) and IL-6. The anti-inflammatory effects of compound K appeared to occur via inhibition of LPS-induced phosphorylation of mitogen-activated protein kinases (MAPKs) and inhibition of NF-κB translocation from the cytosol to the nucleus by suppressing phosphorylation of inhibitory kappa B-α (IκB-α). Furthermore, we showed that compound K inhibited LPS-induced NO generation in an experimental zebrafish model. Considering these results, compound K could potentially be developed as a natural anti-inflammatory agent.

This study evaluated the emissions of specific indoor sources usually present in Portuguese dwellings in order to understand their impact on the indoor air quality. With this aim, three typical activities were studied including home heating using two types of fireplaces (open and closed) and biofuels (pinewood and briquettes), cooking styles (frying and boiling) in different types of kitchen appliances, and several levels of bread toasting. The levels of specific pollutants were found to be above the established Portuguese limit values including VOCs, formaldehyde, and particulate matter (PM2.5 and PM10). Although these emissions are transient and short in duration, the resulting concentrations are high and can severely impact the occupants’ daily exposure. Besides promoting good ventilation, the choice of residential appliances with low emissions should be taken into account. In addition, it is important that occupants perform specific activities following the best practices so that their exposure to pollutants is minimized.
