1 Biomass supply chain equipment for renewable fuels production: A review
تجهیزات زنجیره تأمین زیست توده برای تولید سوخت های تجدیدپذیر: یک مروز-2021
The production of renewable fuels is a critical component of global strategies to reduce greenhouse gas (GHG) emissions. Moreover, the collection of raw materials for its production can provide added benefits such as reduction of wildfire risk, additional income for farmers, and decreased disposal costs. Although there is substantial literature on design and modeling of supply chains, the authors were unable to find a single reference with the information needed for the selection and cost estimation of each type of equipment involved in the supply chain. Therefore, the goal of this research is to gather information necessary for the construction and utilization of models that might drive the identification of a feasible supply chain to produce renewable fuels at a commercial scale. The primary objectives are to 1) understand the supply chain of critical feedstocks for renewable fuels production; 2) identify the equipment commercially available for collection and ad equation of feedstock; and 3) consolidate information regarding equipment cost, energy consumption, and efficiency, as well as feedstock storage and transportation systems. This paper provides a compilation for five feedstock types studied for sustainable aviation fuel production: 1) agricultural residues and grasses, 2) forest residues, 3) urban wood waste, 4) oilseeds, 5) fats, oils & greases. All the technologies involved from the field to the gate of the preprocessing or conversion unit were reviewed. The information on fats, oils & greases supply chains and equipment purposely designed for forest thinning and pruning was very limited.

2 Physicians knowledge and practice concerning diagnosis and management of anaphylaxis: The situation in Egypt
دانش و عمل پزشکان در مورد تشخیص و مدیریت آنافیلاکسی: وضعیت در مصر-2021
Introduction: Early recognition of an anaphylaxis event is crucial for instituting lifesaving management. We sought to explore knowledge and practice towards anaphylaxis in a sample of physicians from ten Egyptian governorates.
Methods: An eighteen question-based questionnaire was developed by expert allergists to evaluate the knowledge and practice towards anaphylaxis, based on the World Allergy Organization guidelines for the assessment and management of anaphylaxis. The questionnaires were distributed, and the answered forms collected via emails, and data were tabulated, and analysed.
Results: In this cross-sectional study, a total of 242 physicians completed the survey (183 (75.6%) paediatricians, 32 (13.2%) internists, 22 (9.1%) intensivists and five (2.1%) anaesthetists). Only 91 participants (37.6%) identified all the four proposed anaphylaxis clinical scenarios while 70, 45 and 36 identified three, two and one scenario, respectively. Loss of consciousness and abdominal symptoms were not recognised as possible presentations of anaphylaxis by 64.5% and 80.2% of the participants, respectively. Epinephrine was considered the first line treatment by 98 (40.5%), corticosteroids by 77 (31.8%) and antihistamines by 25 (10.3%). 75 (31%) responders identified the right dose of epinephrine while 119 (49.2%) identified the proper route. Concerning practice, 83 physicians (39.2%) used epinephrine for all cases of anaphylaxis, 88 (41.5%) used it for refractory cases only whereas 41 (19.3%) did not use epinephrine at all.
Discussion: Our survey shows that the knowledge of Egyptian physicians and their practice towards anaphylaxis are still inadequate. The current situation reinforces the need to disseminate and encourage the adoption of the international guidelines for anaphylaxis diagnosis and treatment.

3 Computer vision techniques on magnetic resonance images for the non-destructive classification and quality prediction of chicken breasts affected by the White-Striping myopathy
تکنیک های بینایی رایانه ای بر روی تصاویر رزونانس مغناطیسی برای طبقه بندی غیر مخرب و پیش بینی کیفیت سینه های مرغ تحت تاثیر میوپاتی White-Striping-2021
This study was designed to assess the capability of MRI-computer vision algorithms, as a non-destructive technique, to classify and predict quality characteristics of chicken breast affected by White-Striping (WS) myopathy. Samples showing moderate and severe degrees of the myopathy were analyzed together with normal samples (no WS symptoms). The influence of the computational algorithms to analyze the MRI images and the techniques of data analysis on the classification and prediction results was aimed. Computational features from both texture (GLCM) and fractal (OPFTA) algorithms were useful to i) classify WS chicken breast by means of different classification technique, Principal Component Analysis and Decision Tree, and ii) predict physico-chemical characteristics of these chicken breast with high accuracy, applying Multiple Linear Regression. The results show the feasibility of objectively classifying chicken breasts without sample destruction into two degrees of severity. This is of remarkable relevance in large processing plants where WS incidence is high and a quick decision-making is required for the fate of affected samples.

4 A vision-based method for automatic tracking of construction machines at nighttime based on deep learning illumination enhancement
یک روش مبتنی بر بینایی برای ردیابی خودکار ماشین های ساختمانی در شب بر اساس افزایش روشنایی یادگیری عمیق-2021
Nighttime construction has been widely conducted in many construction scenarios, but it is also much riskier due to low lighting conditions and fatiguing environments. Therefore, this study proposes a vision-based method specifically for automatic tracking of construction machines at nighttime by integrating the deep learning illu- mination enhancement. Five main modules are involved in the proposed method, including illumination enhancement, machine detection, Kalman filter tracking, machine association, and linear assignment. Then, a testing experiment based on nine nighttime videos is conducted to evaluate the tracking performance using this approach. The results show that the method developed in this study achieved 95.1% in MOTA and 75.9% in MTOP. Compared with the baseline method SORT, the proposed method has improved the tracking robustness of 21.7% in nighttime construction scenarios. The proposed methodology can also be used to help accomplish automated surveillance tasks in nighttime construction to improve the productivity and safety performance.

5 An automatic multi-view disease detection system via Collective Deep Region-based Feature Representation
یک سیستم تشخیص بیماری چند نمایه از طریق نمایندگی ویژگی مبتنی بر منطقه جمعی-2021
With today’s growing requirements in disease diagnosis, we are constantly looking for better solutions. To meet the current demands, a disease detection system being highly effective as well as efficient is required. Existing and popular medical biometrics methods mainly focus on the local features extracted from raw medical image data, rather than study them globally. Meanwhile, prior knowledge is pre- defined in these methods so that procedures are inconsistent and require more manual operations. To address these, we present an automatic multi-view disease detection system, which contains a series of automatic procedures. The system first takes a tuple of images containing the face, tongue, and sublingual vein as the multi-view input, before directly outputting the predicted class label. To perform multi-view disease diagnosis, we propose a collective deep region-based feature representation. In summary, there are three real innovations in this paper: (1) Automated end-to-end medical biometrics system, (2) Deep region-based feature representation, (3) Multi-view multi-disease medical biometrics diagnosis. Extensive experiments were conducted on four diseases and one healthy control group using binary classification, showing both the effectiveness and efficiency of the proposed system. The average accuracy achieved was 95.8%, 96.49%, 96%, and 96.8% for breast tumor, heart disease, fatty liver, and lung tumor versus healthy control group taking 0.0031s, 0.003s, 0.0046s, and 0.0033s to process each sample respectively.© 2020 Elsevier B.V.

6 Experimental investigation of structural system capacity with multiple fatigue cracks
بررسی تجربی ظرفیت سیستم ساختاری با ترک های خستگی متعدد-2021
Few experimental data sets exist in the literature to support the development and evaluation of digital twins predicting structural degradation. The literature is especially sparse for system tests where multiple failures occur and interact. In this work, a laboratory-level experiment is conducted to mimic many of the properties of larger and more complex marine structures with redundant load paths, failure interaction, and component-to-system level integration. In the experiment, such properties are reflected by a hexagon tension specimen with four propagating fatigue cracks tested under displacement-controlled loading. The applied loading cycles and corresponding crack lengths are recorded as the major time-varying data of degradation, with the resisting force at maximum extension used as the system capacity. A novel computer vision method is used to measure the crack length. Strain gauges are also used to monitor the structure’s status. The experimental data is presented and analyzed in this paper. The resulting data sets can be used to evaluate the performance of different digital twin updating approaches.

7 Mothering in accounting: Feminism, motherhood, and making partnership in accountancy in Germany and the UK
مادران در حسابداری: فمینیسم، مادران، و مشارکت در حسابداری در آلمان و انگلستان-2021
Women remain significantly underrepresented at partnership level in accounting firms. The past three decades witnessed a steady increase in investment and research in gender equality in the profession, but there is a scholarly reluctance to focus specifically on motherhood despite the fact that four in five women will have children in their lifetime and experience inequality and discrimination as a result of their status as mothers. This article shares original empirical data of interviews with 60 female partners in Germany and the UK, focusing specifically on their experiences of motherhood and mothering. Theoretically, this article is framed by O’Reilly’s (2016a) matricentric feminism and Gatrell, Cooper and Kossek’s (2017) Douglasian thesis of the maternal body as a social pollutant at work. In Germany, the accounts frequently juxtaposed the maternal body with professionalism, with mothers expected to work part-time, but part-time working patterns deemed irreconcilable with partnership. Becoming a mother was often experienced as representing a burden to others at work. In the UK, the respondents were concerned with accessing maternity leave and returning to work, with some finding it challenging to make claims on the basis of their status as mothers. Half of the mothers were married to ‘househusbands’, often working like normative fathers, with some noting a lack of ‘choice’ in the matter despite their status and financial independence. In both countries, the unencumbered norm was mostly left unchallenged and the task of managing and hiding one’s care responsibilities left for individual women to work out in private, with the primary beneficiary of this concealment being the firm and its clients. The article demonstrates that we must make space for the study of mothering in accountancy if we want to be serious about tackling gender inequality within the profession.

8 Biometric, chemical, and microbiological evaluation of common wheat ( Triticum aestivum L:) seedlings fertilized with mealworm ( Tenebrio molitor L:) larvae meal
ارزیابی بیومتریک ، شیمیایی و میکروبیولوژیکی نهال گندم معمولی (Triticum aestivum L:) بارور شده با پودر لارو کرم غذایی (Tenebrio molitor L:)-2021
Alternative organic fertilizers are being developed to minimize the adverse environmental impact of chemical plant protection agents. The interest in industrial-scale insect farming has increased in recent years. Mealworm larvae are a rich source of protein and fatty acids. This study focuses on mealworm larvae, which are characterized by a rapid increase in biomass and a high nutritional value. In the present experiment, mealworm larvaewere processed into fertilizer with a high content of organic nitrogen. The fertilizer’s effect on wheat growth, soiland rhizosphere microorganisms, including phytopathogenic fungi of the genus Fusarium, and N-cycle, was analyzed. Mineral nitrogen fertilizer and mealworm larvae meal used as fertilizer caused a similar increase (~40%) in the total nitrogen content of the soil. Due to its mineral content, mealworm larvae meal contributed to an increase in the concentrations of P, K, and Mg in soil. The amino acid quality was high (0.89). Increasing the load of Bacillus spp. after using the meal was negatively correlated with the Fusarium spp. load in the wheat rhizosphere. In the case of meal fertilization, ammonification was noticed, and organic nitrogen was successively mineralized. The fertilizer produced from mealworm larvae offers a viable alternative to mineral fertilizers. It improves the health and nutrient status of wheat seedlings and stimulates the growth of Bacillus bacteria that enhance the availability of soil nutrients to plants and prevent seedling damping off. Further research is needed to confirm the applicability of the mealworm fertilizer in other field crops.

9 Investigation of eye tracking, electrodermal activity and facial expressions as biometric signatures of food reward and intake in normal weight adults
بررسی ردیابی چشم ، فعالیت الکترودرمی و حالات چهره به عنوان نشانه های بیومتریک پاداش و مصرف غذا در بزرگسالان با وزن طبیعی-2021
Pervasive exposure to a vast and varied food repertoire has contributed to the obesity epidemic. Within this issue, there is a need for a better understanding of the psychophysiological responses to food cues that precede food choice and food intake to establish how these responses contribute to the link between food availability and increasing obesity levels. Biometric measures such as eye tracking, electrodermal activity and facial expressions may separately or collectively provide deeper insight into psychophysiological processes underlying food reward and food intake. We examined how biometric responses differed in foods varying in fat and taste and explored how these biometric signatures to food cues were related to food preference behaviours, food choice, and food intake. We developed and tested a biometric food preference task designed to concurrently assess biometric responses (eye tracking, electrodermal activity and facial expressions) and food reward to visual food stimuli from different food categories in 100 normal weight adults. Food intake and selection was examined using a simultaneous choice ad libitum buffet. The results from this cross-sectional study showed significant differences in visual attention towards foods varying in fat content and taste prior to making rapid food choice decisions. Furthermore, the study found positive associations between maintained attention during a forced choice paradigm and subsequent food reward and food intake measures. Attention, arousal and facial expression during passive viewing were not associated with food reward or intake measures, except for an association between negative valence and explicit liking such that less liked foods elicited stronger negative facial expressions. The findings indicate that implicit, biometric responses to food cues predict both food reward and actual food intake.

10 A flexible risk assessment framework for marine plastic pollution that synthesizes waste management and ecological impact data
یک چارچوب ارزیابی ریسک انعطاف‌پذیر برای آلودگی پلاستیکی دریایی که داده‌های مدیریت زباله و اثرات زیست‌محیطی را ترکیب می‌کند-2021
The vast quantity of plastic in the world’s ocean poses an urgent problem for marine ecosystems and coastal communities. While considerable research has aimed to understand how plastics impact marine life, there remains a gap in connecting this knowledge with waste management practices. Because these practices often determine the end fate of plastic items, bridging this gap is critical to reducing the flow of harmful plastics into the ocean. The framework proposed here identifies policy actions to reduce consumption of high-impact plastics using a compound risk score that encompasses both an item’s likelihood of entering the ocean and its negative ecological impact. We illustrate the framework’s application using a case study of single-use plastic (SUP) consumption at a large Canadian university. We quantified SUPs purchased over one year at the University of British Columbia and collected data from its associated waste management system to identify factors that influence an item’s end fate. We used these data to estimate the relative risk of items exiting the recycling stream, then combined this with published data on the items’ marine impacts to calculate their compound risk scores. The results identify high-risk plastic items to prioritize in waste reduction strategies and lower-risk alternatives. The results also highlight specific policy avenues to improve the efficiency of the focal waste management system. This framework is flexible to diverse contexts, requiring only information about plastic consumption and waste management practices. It is thus an accessible and useful tool to support local transitions toward a reduced marine footprint.
