Nuclear Medicine Facility Design in Indonesia Based on National Regulation and International Guidelines
Authors: Mayani Anita Nur , Basari Basari
Published: March 2022

Nuclear medicine is a medical science that utilizes radionuclide with gamma ray radiation energy to ionizing the patient’s object either aimed for diagnostic imaging or cancer therapy. Total number of nuclear medicine facilities in Indonesia is 17 hospitals. Unfortunately, there are only 10 hospitals that actively carrying out nuclear medicine services. In order to support the Indonesia cancer management commitment program, the Ministry of Health urges the nuclear medicine facility in Indonesia need to be improved both the quality and facility’s requirement. The standard of nuclear medicine facility services in Indonesia is regulated by the Ministry of Health decree number 008/ MENKES/SK/I/2009, yet unfortunately it has not regulated any specified facility’s technical requirements including layout design, mechanical and electrical aspects. Hence, in this research, we conducted a literature review on the nuclear medicine service facilities’ requirements, referring to the Ministry of Health, the Indonesia Nuclear Energy Agency, and the International Health Facility Guidelines. We conducted thoroughly field observations in ten nuclear medicine facilities in Indonesia to propose the technical requirements and room’s layout design recommendations for nuclear medicine facility in Indonesia. In conclusion of this investigation, the availability of room, utility and instrumentation of nuclear medicine in Indonesia mostly meet the International guidelines, except the room construction aspect. Therefore, our study will promote this shortcoming to fulfill the facility’s requirement recommendation in new regulation of nuclear medicine facilities in Indonesia in the near future for the sake of better patients’ and healthworkers’ safety.
Biological notes on immature stages of Hydaticus pacificus conspersus (Coleoptera: Dytiscidae)
Authors: Watanabe Kohei , Saiki Ryota , Suda Masataka , Yoshida Wataru
Published: March 2022

Hydaticus pacificus conspersus Régimbart, 1899 (Coleoptera: Dytiscidae), is currently considered “endangered,” according to the national Red List of Japan. Herein, the developmental period of the immature stages of H. pacificus conspersus during laboratory rearing is described in detail for the first time. We found that this species deposits eggs not only on aquatic plants but also on the surface of driftwood. The observed durations of developmental stages were as follows: egg period – 3 days; first instar – 1–2 days (1.7 ± 0.5); second instar – 1–4 days (2.4 ± 0.6); third instar – 4–7 days (5.0 ± 0.7 days); and construction of a pupal chamber to emergence: 8–13 days (9.6 ± 0.8). Based on these observed results, H. pacificus conspersus has one of the shortest larval developmental periods among the Dytiscidae species. The short larval period and the ability to lay eggs on substrates other than plants may be an adaption of the species to increase reproductive success in unstable environments.
La contraccezione nelle fonti e nella storia islamica
Authors: Atighetchi Dariusch
Published: March 2022

Il silenzio del Corano nei confronti della contraccezione viene compensato dalle parole risalenti al Profeta Muhammad le quali, in maggioranza, non proibirono il coitus interruptus. Questa: tolleranza è stata ripresa dalla tradizione islamica che ha trovato in al-Ghazali il più apprezzato formulatore dei criteri da rispettare per legittimare la pratica del coitus interruptus e, in seguito, delle moderne tecniche contraccettive. Secondo il pensiero di Ghazali il coitus interruptus è un'azione makruh, vale a dire, per le categorie della Legge islamica, un atto riprovevole, ma, nello stesso tempo, tollerato. Oggi, la gran parte dei giuristi musulmani accettano le pratiche contraccettive pur con sfumature diverse. Più differenziata appare la politica demografica degli stati Arabo-Islamici che oscillano dalla proibizione ad un accoglimento più o meno ampio delle varie tecniche anticoncezionali.

Aedes aegypti plays an important role in the transmission of several arboviruses of medical importance. The availability of information on the blood-feeding preferences of mosquito vectors is a critical step in the understanding of the transmission of human pathogens and implementation of control strategies. In Senegal, no data currently exist on the feeding pattern of Ae. aegypti in urban areas. To fill this gap, Ae. aegypti blood-fed females were collected in five localities by aspiration and using BG Sentinel 2 traps. Collections were carried out monthly between July and November 2019 inside and outside human dwellings. The origin of the blood meal of Ae. aegypti females were identified by an ELISA technique. A total of 1,710 blood-engorged females were examined and showed that Ae. aegypti preferentially fed on human with 78.6% of the identified blood meals. The other blood meals were from animals including dog, cat, horse, cattle, sheep, and rat. This is the first report on the feeding behavior of Ae. aegypti in urban settings in West Africa. It demonstrated that this species is highly anthropophilic.

Malaria transmission has declined substantially in Southern Province, Zambia, which is considered a low-transmission setting. The Zambian government introduced a reactive test-and-treat strategy to identify active zones of transmission and treat parasitemic residents. This study was conducted in the Choma District, Southern Province, Zambia, concurrently with an evaluation of this strategy to identify vectors responsible for sustaining transmission, and to identify entomological, spatial, and ecological risk factors associated with increased densities of mosquitoes. Anophelines were collected with CDC light traps indoors and near animal pens in index cases and neighboring households. Outdoor collections captured significantly more anophelines than indoor traps, and 10 different anopheline species were identified. Four species (Anopheles arabiensis, An. rufipes, An. squamosus, and An. coustani) were positive for Plasmodium falciparum circumsporozoite protein by ELISA, and 61% of these 26 anophelines were captured outdoors. Blood meal assays confirm plasticity in An. arabiensis foraging, feeding both on humans and animals, whereas An. rufipes, An. squamosus, and An. coustani were largely zoophilic and exophilic. Linear regression of count data for indoor traps revealed that households with at least one parasitemic resident by polymerase chain reaction testing was associated with higher female anopheline counts. This suggests that targeting households with parasitemic individuals for vector interventions may reduce indoor anopheline populations. However, many vectors species responsible for transmission may not be affected by indoor interventions because they are primarily exophilic and forage opportunistically. These data underscore the necessity for further evaluation of vector surveillance and control tools that are effective outdoors, in conjunction with current indoor-based interventions.

Trachoma is the leading infectious cause of blindness. In 2016, Morocco was validated by WHO as having eliminated trachoma as a public health problem. We evaluated two previously endemic districts in Morocco for trachomatous inflammation—follicular (TF), trachomatous trichiasis (TT), and antibodies against Chlamydia trachomatis, the causative agent of trachoma. Community-based cross-sectional surveys in the districts of Boumalene Dades and Agdez included 4,445 participants for whom both questionnaire and serology data were available; 58% were aged 1–9 years. Participants had eyes examined for TF and blood collected for analysis of antibodies to the C. trachomatis antigen Pgp3 by both a multiplex bead assay (MBA) and lateral flow assay (LFA). Seroconversion rates (SCR) per 100 people per year were used to estimate changes in the force of infection using Bayesian serocatalytic models. In Agdez, TF prevalence in 1–9-year-olds was 0.3%, seroprevalence ranged from 9.4% to 11.4%, and SCR estimates ranged from 2.4 to 3.0. In Boumalene Dades, TF prevalence in 1–9-year-olds was 0.07%, and modeling data from the different assays indicated a decrease in transmission between 20 and 24 years ago. The TF data support an absence of active trachoma in the two districts examined. However, seroprevalence and SCR in younger people were higher in Agdez than Boumalene Dades, showing that there can be differences in serology metrics in areas with similar TF prevalence. Data will be included in multicountry analyses to better understand potential thresholds for serological surveillance in trachoma.
Multi-component reactions of cyclohexan-1,3-dione to synthesize heterocyclic derivatives with c-Met enzymatic activity, anti-prostate, anti-proliferative and tyrosine kinase activities
Authors: Mohareb Rafat Milad , Ibrahim Rehab Ali , Alwan Ensaf Sultan
Published: March 2022

ABSTRACT. We are aiming in this work to synthesize target molecules not only possess anti-tumor activities but also kinase inhibitors. The target molecules were obtained starting from aryl hydrazones of cyclohexan-1,3-dione  followed by its heterocyclization reactions to produce anticancer molecules. The multi-component reactions of the arylhydrazocyclohexan-1,3-dione derivatives 3a-c produced the 1,4,5,6,7,8-hexahydroquinoline derivatives 6a-r and the 4,5,6,8-tetrahydrochromeno[2,3-c]pyrazole derivatives 10a-c. Other multi-component reactions were demonstrated. The anti-proliferative activity of the synthesized compounds toward the six cancer cell lines namely A549, H460, HT-29, MKN-45, U87MG, and SMMC-7721 was studied. In addition the c-Met enzymatic activities and inhibition toward the prostate cancer cell PC-3 were measured. The results obtained in most cases, indicated that the presence of electronegative Cl group through the molecule favour the inhibitions.

ABSTRACT. This study involves synthesis of new substituted of cobalt phthalocyanine derivatives (CoPc) from starting materials naphthalene-1,4,5, tetracarbonic acid dianhydride (NDI) and phthalic anhydride by dry process. Nano composites materials were prepared from multi wall carbon nanotubes (MWCNTs), and MO (Cr2O3-NiO) to yield (MWCNTs/MO) nanocomposite and mixed with cobalt phthalocyanine to yield (MWCNTs/CoPc-MO). These materials were investigated using different analytical and spectrophotometric methods such as FTIR spectroscopy, X-rays diffraction (XRD), and scanning electron microscopy (SEM). Then the activity of these materials was investigated by conducting photocatalytic oxidation of butann-2-ol over a suspension of these composites under irradiation with UV light from middle pressure mercury lamp. The concentration of the produced 2-butanone was followed by spectrophotometric method using 2,4-dinitro phenyl hydrazone which was detected by measuring absorbance at 480 nm. Different reaction conditions and parameters were investigated such as effect of weight of the catalyst, temperature of reaction, reaction period and the effect of pH of reaction mixture.

Published: March 2022

ABSTRACT. In dye-sensitized solar cells, transparent metal oxide working electrodes play a vital role in defining the power conversion efficiency. It was found that the size of nanoparticles influences the electrical, optical properties of these electrodes. Herein, we describe the synthesis of ZnO with zinc acetate dihydrate and different stabilizers (diethylamine and triethylamine) by using a modified solvothermal process. The obtained materials were characterized by XRD, SEM, EDX, TEM, HRTEM, UV-visible, FTIR, and Raman methods. The crystallite sizes for ZnO-1 and ZnO-2 samples were indexed as 39.0 and 40.5 nm for the highest peak intensity with diethylamine and triethylamine stabilizer, respectively. We examine the effect of stabilizers on the morphology, optical band gap, and photovoltaic performance of the prepared ZnO. We found that ZnO prepared using diethylamine stabilizer exhibiting significant efficiency of 1.45%, open-circuit voltage 0.454 V, short-circuit current density 2.128 mA/cm2, and 0.66 fill factor were achieved under 44 mW/cm2 illumination powers with dye-3.

Investigation of turbidity removal and energy consumption from pistachio processing industry wastewater by electro-oxidation process
Authors: Fil Baybars Ali , Günaslan Sermin
Published: March 2022

ABSTRACT. In this study, it was aimed to remove turbidity, which is an important parameter of water quality, and to examine energy consumption from pistachio processing industry wastewater (PPIW). As working parameters, mixing speed, supporting electrolyte (SE) type and concentration, initial pH value of wastewater, and current density were examined. Graphite was used as the anode material, and stainless steel was used as the cathode material. The highest removal for the mixing speed parameter was achieved at 400 rpm, the maximum efficiency for the SE type was achieved at NaCl, a concentration of 2 M for the SE concentration, a pH of 3.0 for the wastewater initial pH value, and a current density of 30 mA/cm2. However, considering the energy consumption cost in these parameters, the optimal conditions were determined as 1.25 M of SE, pH 3.0, mixing speed of 400 rpm, and current density of 6 mA/cm2. In these conditions, the turbidity removal efficiency was found to be 90.61%. Energy consumption for the same conditions is calculated at 180 kWh/m3. In the results obtained, it is observed that energy consumption decreases as the concentration of SE increases. NaCl, which is the electrolyte that provides maximum efficiency in removing turbidity, is also the electrolyte that provides minimum energy consumption. In electrochemical systems, the cost is as important as lifting efficiency. Therefore, the choice should be made, considering which of these two parameters will be the priority.

“Supplication for the quickest possible conclusion.” Analysis of source materials regarding magnate pre-wedding negotiations (example of the marriage of Teresa Barbara Radziwiłł with Józef Scipion del Campo)

The presented research is based on source materials regarding magnate pre-wedding negotiations. The handwritten notes were made on the occasion of the second marriage of Józef Scipion del Campo (died 1743), the Lithuanian court marshal, with Teresa Barbara née Radziwiłł (died 1780). The subject of the analysis are preserved documents revealing a number of legal and property-related problems that determined the process of the pre-wedding negotiations. Scipion del Campo sought to tie the knot with the wealthy daughter of Mikołaj Faustyn Radziwiłł, counting on tangible benefits that could be brought to him by the affinity with the influential family. The analysis of the unique source materials has made it possible to trace the negotiation process preceding the marriage, along with the identification of the most important problem points. The preserved documents prove that it was possible to change the final arrangements (dowry, annuity, some economical aspects). The analysis significantly enriches knowledge about the matrimonial policy implemented in the noble circles of the Polish-Lithuanian Commonwealth.

Published: March 2022

Religious tourism and pilgrimage are theocentric terms that refer to people visiting holy and sacred shrines seeking; God’s indulgence and absolution of sins in the afterlife, spiritual and physical healing, regeneration of the soul and spirit, acquiring new religious and cultural experiences, a shorter stay in the purgatory and a transcendence of one’s former frame of reference. Religious tourism and pilgrimage have a strong potential to: create quality employment opportunities, increase local community resilience against poverty, curtail rural flight migration, foster mutual understanding, respect, peace and harmony among tourist, pilgrims, local communities, and even countries, and importantly may contribute to rapid national growth and development. The study used a multiple paradigm approach to investigate motives for visiting
ZCC Mbungo Shrine in Zimbabwe by religious tourists and pilgrims. Data was collected using representative focus group made up of 10 participants and revelatory focus group consisting of 5 participants. Our findings show that religious tourists and pilgrims to ZCC Mbungo Shrine are motivated by the quest for spiritual and physical healing, new cultural experiences, piety, religious affiliation and veneration of the founding member. The study recommends improving tourist facilitating conditions, promotion of eco-tourism and cultural tourism alongside religious tourism and pilgrimages to the shrine.
Cost-Benefit Analysis of Green Infrastructure for Sustainable Stormwater Management of the Built Environment
Authors: Aladesote Olatunde J
Published: March 2022

Green infrastructure is a modern network of decentralized stormwater management applications that can capture and infiltrate rain where it falls, thus diminishing stormwater runoff and improving the health of surrounding waterways. While there are unique scales of green infrastructure, such as large swaths of land set aside for preservation. Green infrastructure such as bioretention, green roofs, trees, and permeable pavement is important in today’s world since many municipalities are faced with the issues of aging gray infrastructure, impaired local water way, and projected population growth by 2030. Green stormwater infrastructure helps strengthen communities’ economy while providing environmentally and economically sustainable solutions to stormwater management issues. This study found that current stormwater runoff issues in municipalities across the United States will be substantially decreased with about 1.05 billion gallons diverted from sewer. This will yield about millions of dollars in annual savings and decrease buildings energy metered water use by 1.37 million kWh of carbon dioxide. Green infrastructure is needed to address and plan for the future impacts of climate change by preventing increased flood risks and public health stresses.

Foraminifera in the glacial erratic rock Heiligenhafener Kieselgestein of northern Germany
Authors: Hesemann Michael
Published: March 2022

In this study the foraminifera of the glacial erratic Heiligenhafener Kieselgestein (HKG) consisting of siliceous sandstones are documented for the first time. The glacial erratics in northern Germany were deposited during the Pleistocene. The age of the HKG sandstone is indicated as Eocene from 49.6 Ma to 47.8 Ma. The lower limit is given by the first occurrence of the planktonic foraminifera Pseudohastigerina micra (Cole 1927). The upper limit is derived from previous studies of the Eocene succession of Northern Germany based on benthic foraminiferal faunas. The HKG fauna indicates a boreal, fully marine environment characteristic for a water depth between 50 m and 80 m.

Published: March 2022

The Upper Cretaceous successions of the Arabian Platform in Batman and surroundings (SE Turkey) comprise the Garzan and Lower Germav formations. Shallow water limestones of the Garzan Formation contain rich benthic foraminiferal assemblages. The conformably overlying LowerGermav Formation consists mostly of marls and includes planktonic foraminifera, which suggest a relatively deeper marine environment. Benthic and planktonic foraminiferal assemblages fromboth formations were studied in 28 samples collected from a 155-m-thickmeasured section. Diverse benthic foraminiferal assemblages are mainly dominated by Orbitoides megaloformis Papp and KÃ¼pper, O. media (dâ€™Archiac), Omphalocyclus anatoliensis Ozcan, Dicyclina schlumbergeri Munier-Chalmas, Trochospira avnimelechi Hamaoui, Nezzazata simplex Omara, Nezzazatinella picardi (Henson), Antalyna korayi Farinacci and Koyluoglu, Fleuryana adriatica (DeCastro), Biconcava bentori Hamaoui, Cuneolina pavonia dâ€™Orbigny,C. ketini Inan, Moncharmontia apenninica (DeCastro), M. compressa (De Castro), Fissoelphidium operculiferum Smout and Vandenbroekia munieri Marie. Themajority of Late Cretaceous taxa are long-ranging. Orbitoides media and O. megaloformis within this assemblage have been documented both in the upper Campanian and Maastrichtian strata from the Tethyan Province. The age of the Garzan Formation is determined to be Maastrichtian based on the presence of Antalyna korayi, C. ketini and Fleuryana adriaticia. The abundance of opportunist planktonic foraminifera (i.e., biserial heterohelicids and rugoglobigerinids) throughout the Lower Germav Formation shows that the environmentwas not very deep during the deposition of the unit. Maastrichtian taxa such as Globotruncanita conica (White) and Globotruncanella minuta Caron and Gonzales Donoso appear in the middle part of the Lower Germav Formation, but these are absent from the lower part of the formation.

Neste artigo, propomos discutir como a produção de narrativas colonizadoras estruturadas por dispositivos de gênero, raça e sexualidade expressaram-se sobre corp@s colonizadas de mulheres sul baianas, localizando a discussão a partir do contexto histórico e social do município de Canavieiras-Bahia. Nosso argumento é que as narrativas de apagamento, de opressão e de negatividade implementadas pelo colonialismo, no sul da Bahia, foram orquestradas sobre corp@s racializadas e sexualizadas de mulheres negras e indígenas, pois tomamos como referência o modo como estas foram destituídas de suas vontades e subjetividades, assim como animalizadas. Tentamos compreender como tais elaborações vêm sendo produzidas e contestadas através de uma abordagem teórica e metodológica, cuja ferramenta analítica da interseccionalidade nos ajuda a pensar o entrecruzamento dos eixos dos sistemas de dominação e de seus enfrentamentos cotidianos, por parte de negras e indígenas.
Maternidades subalternas
Authors: Santos Almeida Miléia
Published: March 2022

O debate sobre a construção social e cultural da maternidade, sua dimensão de controle dos corpos e da reprodução das mulheres, é um terreno bastante consolidado na teoria feminista ocidental. Não somente a História, mas a Filosofia, as Ciências Sociais, a Psicologia, entre outros campos, dedicaram muitas páginas às reflexões sobre os condicionamentos de gênero presentes no mito de um amor materno inato e incondicional. Entretanto, assim como não é possível conceber uma forma universal de ser mulher, se faz necessário entender que não existe uma única forma de ser mãe, mas sim formas plurais de maternidades, algumas delas subalternizadas e/ou marginalizadas pelo processo colonizador. Nesse sentido, as contribuições dos feminismos negro e decolonial são fundamentais para romper os limites existentes em uma perspectiva feminista eurocêntrica, branca e burguesa/liberal que, por muito tempo permaneceu alheia a diversidade das questões das mulheres ou mesmo conivente com um processo de dominação-exploração-opressão sobre suas vidas. Tais estudos permitem assim, “descolonizar” o olhar acerca da maternidade e das relações de gênero, para consolidação de uma epistemologia feminista, antirracista, anticapitalista e anticolonial. Essa é então a principal contribuição do presente artigo que, por meio de uma análise teórico-bibliográfica de orientação prática, interroga as maternidades subalternas enquanto chave de leitura da experiência de mulheres não-brancas em contextos pós-coloniais.
A luta pela educação escolar indígena como resistência epistemológica
Authors: Penteado Urban Samuel
Published: March 2022

O objetivo principal do desenvolvimento da entrevista com o Cacique Luiz katu (José Luiz Soares) foi o de conhecer a luta pela educação escolar indígena no estado do Rio Grande do Norte, mais especificamente no que se refere ao Ensino Fundamental. E isso tem a ver a denúncia de uma situação desumanizante, e que gerou o anúncio por meio de uma resistência epistemológica. Cacique Luiz Katu recebeu o entrevistador, de forma virtual, em 27 de maio de 2020. Cabe destacar, que diálogo com o Cacique foi orientado pelas diretrizes da entrevista semiestruturada e, assim, contou com um roteiro de questões previamente formulado pelo entrevistador. Ele foi dividido em quatro temas (questões): relação do entrevistado com a educação, início das atividades no magistério, luta pela educação indígena na aldeia e no estado do Rio Grande do Norte e, por fim, questões pontuais acerca da escola existente na aldeia.
Modern Historiography in the Making
Authors: Eskildsen Kasper Risbjerg
Published: March 2022

At the end of the 19th century, German historical scholarship had grown to great prominence. Academics around the world imitated their German colleagues. Intellectuals described historical scholarship as a foundation of the modern worldview. To many, the modern age was an ‘age of history’. This book investigates how German historical scholarship acquired this status.

Modern Historiography in the Making begins with the early Enlightenment, when scholars embraced the study of the past as a modernizing project, undermining dogmatic systems of belief and promoting progressive ideals, such a tolerance, open mindedness and reform-readiness. Kasper Risbjerg Eskildsen looks at how this modernizing project remained an important motivation and justification for historical scholarship until the 20th century. Eskildsen successfully argues that German historical scholarship was not, as we have been told since the early 20th century, a product of historicism, but rather of Enlightenment ideals. The book offers this radical revision of the history of scholarship by focusing on practices of research and education. It examines how scholars worked and why they cared. It shows how their efforts forever changed our relationship not only to the past, but also to the world we live in.

Authors: Cardoso Pedro Henrique , O’Leary Nataly , Olmstead Richard G. , Moroni Pablo , Thode Verônica A.
Published: March 2022

Background and aims – The last comprehensive study that estimated the number of Verbenaceae genera and species was published in 2004, and included 34 genera and around 1200 species. Since then, several publications based on morphology and/or molecular data have proposed important changes within the family. Due to the lack of updated literature to cite when referring to the number of Verbenaceae taxa, a review of these estimates is necessary.Key results and conclusion – We present a detailed list of genera currently accepted in Verbenaceae with the number of species contained in each and compare our numbers with the previous estimate. In addition, we indicate the geographic distribution and the most recent important taxonomic or phylogenetic works for each genus. Our compilation shows that Verbenaceae have 32 genera and 800 species currently accepted.This work provides up-to-date numbers and brings a holistic view of the family.
A rare coexistence of acute thrombotic occlusion
of the left popliteal-tibioperoneal artery and the left iliofemoral vein: a case report
Authors: Yilmaz Seyhan , Zengin Sabur
Published: March 2022

Background: Acute arterial occlusion is a vascular emergency, which is characterized by a sudden interrupted perfusion of the limbs and deep vein thrombosis is a common complication of long-term hospitalizations and a preventable cause of in-hospital deaths.
Case report: Here, we reported a rare coexistence of acute thrombotic occlusion of the left popliteal-tibioperoneal artery and acute iliofemoral vein thrombosis at the same limb admitted to emergency department, which was succesfully treated with surgical thrombectomy and pharmacomechanical thrombectomy combined with catheter directed thrombolysis procedure.
Conclusion: It is important to recognize and differentiate acute arterial and deep venous thrombosis at the first admission to the emergency department in terms of optimal treatment and patient management, but physicians should remember that these clinical conditions can be seen together especially in patients with risk factors.

Purpose

This study compares the physiological demands of 30-15 Intermittent Fitness Test (30-15IFT), Yo-Yo Intermittent Recovery Test level 1 (YYIRT), and VAMEVAL test as related to training and match demands among youth soccer players.

Methods

Overall, 12 under-19 male soccer players (18.21 ± 0.34 years old) were monitored over 3 consecutive weeks for heart rate (HR) responses during training sessions and matches. During this period, they were assessed with 30-15IFT, YYIRT, and VAMEVAL. The measures were taken on the same day of the week to ensure replicable conditions between the tests.

Results

The Friedman test revealed significant differences in the average HR (p = 0.006), time in HR zone 3 (p < 0.001), and time in HR zone 4 (p = 0.039) between the tests. Considering the representativeness of the tests in comparison with training sessions and matches, both 30-15IFT and VAMEVAL corresponded to 48% and 46% of the training session load 3 days before the match day (936 ± 447 s) and on the match day (831 ± 533 s), respectively.

Conclusions

YYIRT imposed greater time exposure to high HR intensities (in the zones of 80–100% of HR maximum) than VAMEVAL and 30-15IFT. Moreover, the multistage fitness tests corresponded to slightly more than half of the time in which a player was exposed to 80% and 100% of HR maximum during a regular training session and match day. These findings may assist coaches in understanding how to incorporate intermittent fitness tests within training in order to accurately replicate HR responses of match conditions.

In automotive electronics, new technologies are getting integrated into basic framework creating ways for new software-defined architectures. Virtualization is one of most discussed technologies which will offer a functionality growth into architecture of automobile. This paper introduces concept of validating test cases from multiple IPs on virtualised framework and also investigate the feasibility of implementing protection mechanism on memory segment dedicated for a virtual machine (VM). We describe a proof-of-concept which can be used to promote the use of virtualisation to extend the coverage of post silicon validation. Experimental results are presented as a quantitative evaluation of using virtualization for different testcase scenarios.
Runway Extraction and Improved Mapping from Space Imagery
Authors: A. Noever David
Published: March 2022

Change detection methods applied to monitoring key infrastructure like airport runways represent an important capability for disaster relief and urban planning. The present work identifies two generative adversarial networks (GAN) architectures that translate reversibly between plausible runway maps and satellite imagery. The training capability was illustrated using paired images (satellite-map) from the same point of view and using the Pix2Pix architecture or conditional GANs. In the absence of available pairs, the CycleGAN architecture likewise showed that its four network heads (discriminator-generator pairs) also provided effective style transfer from raw image pixels to outline or feature maps. To emphasize the runway and tarmac boundaries, the experiments show that the traditional grey-tan map palette is not a required training input but can be augmented by higher contrast mapping palettes (redblack) for sharper runway boundaries. The research highlights a potentially novel use case (called “sketch2satellite”) where a human sketches the current runway boundaries and automates the machine output of plausible satellite images. Finally, faulty runway maps were identified where the published satellite and mapped runways disagree, but an automated update renders the correct map using GANs.
An IR-based QA System for Impact of Social Determinants of Health on Covid-19
Authors: Addagudi Priyanka , MacCaull Wendy
Published: March 2022

Question Answering (QA), a branch of Natural Language Processing (NLP), automates information retrieval of answers to natural language questions from databases or documents without human intervention. Motivated by the COVID-19 pandemic and the increasing awareness of Social Determinants of Health (SDoH), we built a prototype QA system that combines NLP, semantics, and IR systems with the focus on SDoH and COVID-19. Our goal was to demonstrate how such technologies could be leveraged to allow decision-makers to retrieve answers to queries from very large databases of documents. We used documents from CORD-19 and PubMed datasets, merged the COVID-19 (CODO) ontology with published ontologies for homelessness and gender, and used the mean average precision metric to evaluate the system. Given the interdisciplinary nature of this research, we provide details of the methodologies used. We anticipate that QA systems can play a significant role in providing information leading to improved health outcomes.
ESGBERT: Language Model to Help with Classification Tasks Related to Companies’ Environmental, Social, and Governance Practices

Published: March 2022

Environmental, Social, and Governance (ESG) are non-financial factors that are garnering attention from investors as they increasingly look to apply these as part of their analysis to identify material risks and growth opportunities. Some of this attention is also driven by clients who, now more aware than ever, are demanding for their money to be managed and invested responsibly. As the interest in ESG grows, so does the need for investors to have access to consumable ESG information. Since most of it is in text form in reports, disclosures, press releases, and 10-Q filings, we see a need for sophisticated natural language processing (NLP) techniques for classification tasks for ESG text. We hypothesize that an ESG domain specific pre-trained model will help with such and study building of the same in this paper. We explored doing this by fine-tuning BERT’s pre-trained weights using ESG specific text and then further fine-tuning the model for a classification task. We were able to achieve accuracy better than the original BERT and baseline models in environment-specific classification tasks.
