Published: September 2021

We describe a new case of duodenal wound with complete transection in a 22-year-old patient following a motorcycle accident. He presented to the emergency room of the rural Regional Hospital of Edéa in Cameroon with a clinical picture of acute abdomen and post-trauma hemodynamic instability. A peritoneal puncture brought back an incoagulable blood. An exploratory laparotomy revealed a large hemoperitoneum mixed with food debris. A tear of the omentum and transverse mesocolon and a complete section of the third duodenum at the beginning of its free portion were observed. The surgeon performed emergency closure of both duodenal stumps and performed an isoperistaltic lateral gastrojejunal bypass. A transfer to a specialized center for a more anatomical continuity was considered, but the imminence of a humanitarian mission in the hospital prompted the surgeon to seize the opportunity of this mission for the reoperation. This surgical revision was performed on the fifth postoperative day. A resection of the distal duodenal stump and the adjacent jejunal segment including the anastomosis was performed. Continuity was restored by a mechanical duodenal-jejunal anastomosis. The patient was discharged on the 18th postoperative day. This type of lesion is difficult to manage in an emergency situation in a structure with limited technical resources. Unfortunately, surgeons treating polytraumatized civilians are encountering an increasing number of blunt duodenal wounds requiring laborious management.

Published: September 2021

Imagens mamográficas têm sido cada vez mais importantes na luta contra o câncer de mama. Uma nova técnica de imageamento, denominada mamografia digital contrastada de dupla energia, tem ganhado destaque na avaliação de lesões suspeitas. Essa técnica consiste no uso de um agente contrastante e na exposição da mama em feixes de baixa e alta energia. O objetivo desse trabalho é determinar as curvas de transmissão dos feixes empregados em mamografia digital contrastada, através de diferentes materiais utilizados como blindagem, e seus parâmetros de ajuste α, β e γ. A metodologia foi baseada no método Monte Carlo, utilizando o código PENELOPE. Os resultados mostraram grandes diferenças entre as curvas de transmissão entre os feixes de baixa e alta energia. O parâmetro α diminui com o aumento do potencial do tubo, enquanto β e γ não apresentam uma tendência geral. De modo geral, os resultados obtidos reforçam a importância de se considerar dados de transmissão apropriados para cada técnica de imagem.

As propriedades ópticas de tecidos biológicos podem ser utilizadas como parâmetros indicativos de alterações tanto morfológicas quanto fisiológicas nos tecidos. A técnica de imagens ópticas no domínio da frequência espacial (SFDI) vem apresentando grande potencial determinação dessas propriedades. Neste trabalho, investigamos a utilização de Redes Neurais Artificiais (RNA) para reconhecimento de padrões, na determinação das propriedades ópticas de tecidos, através dos coeficientes de absorção e espalhamento reduzido,  e , a partir de dados de refletância difusa fornecidos pela técnica SFDI. Empregou-se uma RNA do tipo feedforward com uma camada oculta e 50 neurônios, utilizando aprendizagem supervisionada por retropropagação de erros. O treinamento da rede foi realizado a partir de um conjunto de valores pré-determinados de refletância difusa e coeficientes de absorção e espalhamento obtidos a partir de simulações Monte Carlo. Os resultados mostraram que a RNA pode determinar com boa precisão as propriedades ópticas a partir de dados de refletância difusa, fornecendo valores de  e  com coeficientes de determinação R2 de 0.98 e 0.97, respectivamente, em relação aos valores verdadeiros, e apresentando erros médios percentuais de 2.6 e 4.9% para cada coeficiente. A RNA obtida foi então empregada, em conjunto com a técnica SFDI, em uma investigação para obtenção de imagens de regiões da pele de um indivíduo que apresentava uma lesão. Os resultados obtidos apontam para o potencial da utilização de técnicas de inteligência artificial combinadas à SFDI para detecção e identificação de alterações dermatológicas.
Justiça, Paz e Integridade da Criação e o “Deus quente” do mercado total
Authors: Assmann Hugo
Published: September 2021

Se o título acima continuar um tanto enigmático para alguém, aproveito este fato para confessar um vício secreto: sou colecionador de pérolas teológicas extraídas de textos econômicos. Levei tão adiante esta minha exótica paixão, ao longo dos últimos dez anos, que me enamorei deveras do binômio “economia e teologia”. Isso me levou a perpetrar alguns artigos sobre o assunto, além de, mais recentemente, um modesto ensaio sobre a “idolatria do mercado”. Em outras palavras, nutro atualmente um interesse, entusiasta e juvenil, pela incrível versatilidade dos “deuses maiores”, que os economistas cultuam em suas teorias econômicas. É fantástico descobrir que se trata de “deuses verdadeiros”, porque os deuses sempre são verdadeiros para quem os cultua, e os deuses da “religião econômica” recebem, sem sombra de dúvida, um culto notável.

Published: September 2021

Marketing has drastically changed in the last two decades. It has been transformed from traditional to experiential science where organizations are constrained to adopt the strategical and experiential models to survive, grow, and lead in today’s cutting edge completion. In such a case, service experience has become a central point of exploration of how it could positively influence customer behavioral outcomes. In this study, the relationship between service experience and university passion surrounded by basic psychological need theory is explored in the context of education.  A non-probability e-convenience sampling technique was adopted and a total of 432 respondents contributed to this research by submitting their responses. The data were analyzed using the latest version of SmartPLS. The structural equation modeling was used to explore the hypothetical relationship between all latent variables i.e. service experience, esthetics, escapist, entertainment, education, basic psychological need, and university passion. The results of this study have revealed that consumers with extraordinary service experience are likely to be passionate keeping in view their basic psychological needs. Thus, university passion is directly linked with the service experience offered by the university.
conceptual review of capital structure under risk-based capital regime, risk profile of insurer’s and performance
Authors: Bhutto Sarfaraz Ahmed , Ghumro Ikhtiar Ali , Rajper Zulfiqar Ali , Shaikh Saifullah
Published: September 2021

This paper evaluates capital structure under risk-based capital regime from the perspective of insurance firms and its performance. It also evaluates the moderating effect of insurer’s risk profile on capital-performance relationship. The authors aim to reveal ambiguities, gaps and omissions in the literature and to sketch avenues for future research. A conceptual framework for capital structure under risk-based capital era and its application is suggested focusing on equity, technical provision and required risk propensity for maximizing profit and wealth for all stakeholders. The research reviews that capital structure of insurers differs from non-insurance firms as such risk-based capital regulation must not only focus on the various types of risk but also recognized these differences. It is shown that insurers’ capital structure contains equity and technical provisions which comprises accruals and creditors, payable claims and insurance funds as an alternative of equity and financial debt as it is with conventional non insurance firms. This study thus stressed that for capital structure to best explain performance of insurers, it must be measured by equity ratio and technical provision ratio in place of debt ratio and corporate risk profile (quantitative and qualitative) must enter its sequence of performance relational analysis and effectiveness equations. We stressed further that only with the proposed conceptual framework would a holistic understanding of insurer’s capital structure be achieved while the observed contradictory and inconclusive empirical findings on capital structure and firm performance could be resolved.
Breast Cancer Detection via Global and Local Features using Digital Histology Images
Authors: Murtaza Ghulam , Abdul Wahab Ainuddin Wahid , Raza Ghulam , Shuib Liyana
Published: September 2021

Globally, breast cancer (BC) is the prevailing cause of unusual deaths in women. Breast tumor (BT) is a primary symptom and may lead to BC. Digital histology (DH) image modality is a gold standard medical test for a definite diagnosis of BC. Traditionally, DH images are visually examined by two or more pathologists to come up with a consensus for authentic BC detection which may cause a high error rate. Therefore, researchers had developed automated BC detection models using a machine learning (ML) based approach. Thus, this study aims to develop a BC detection model through ten feature extraction methods which extract both local and global type features from publicly available breast histology dataset. The extracted features are sorted by their weights, which are computed by the neighborhood component analysis method. A feature selection algorithm is developed to find the minimum number of discriminating features, evaluated through seven heterogeneous traditional ML classifiers. The proposed ML-based BC detection model acquired 90% accuracy for the initial testing set using 51 Harris features. Whereas, for the extended testing set, only three Harris features is shown 93% accuracy. The proposed BC detection model can assist the doctor in giving a second opinion.

Published: September 2021

The current study aims to analyze the application of reader response theory in literature classrooms. It focuses on the potential reader response teachers at a public sector university, Pakistan and their questioning practices in classrooms based on Probst’s (1994) suggested model. Probst (1994) has given five model generic questions for reader response teachers. For this purpose a sample of three teachers of English Literature has been picked up through non probability purposive sampling method. Data is collected through recorded systematic class observation where focus was on the questions asked by the teachers. Substantial amount of literature related to reader response theory and its application in classroom is also discussed which supports the findings of this research. Through observation of teachers’ classes and analysis of data, researchers advocate the use of reader response teaching methods in literature classrooms at university level. The Study further concludes that the types of questions, teachers ask impact hugely the understanding of students. Data indicates that a classroom can only be reader response when students are given space, freedom and are encouraged to discuss and give answers of open ended questions. Study also suggests, teachers’ training and academic excellence also affect the degree to which a class can be reader response. So, it is necessary that teachers should be aware of reader response methods and the ways of its application in the classroom
Low Loss Transmission Circular Polarizer for KU Band Application
Authors: Mangi Farman Ali
Published: September 2021

Low loss transmission circular polarizer is proposed for Ku band applications. The designed structure consists of two closely cross metallic strips which are based on FSS for 15.25 GHz and 15.28 GHz applications. The right hand circular polarization (RHCP) and left handed circular polarization (LHCP) are obtained at 15.25 GHz and at 15.28 GHz. The transmission loss through polarizer is important issue for high frequency applications. Due to transmission loss, new techniques are required to reduce the transmission loss of transmitted wave and achieve perfect circular polarization. Meanwhile, low loss transmission has been achieved by using dual layer of strips to obtain perfect circular polarization at certain mentioned resonant frequencies. Theoretically, it is found that the outgoing waves through polarizer are perfect circular polarization at the distinct frequency ranges.

Published: September 2021

The research paper presents the control strategy to reduce THD (Total Harmonic Distortions) losses by the implementation of the Nearest Level Modulation control technique in a Modular Multilevel Converter. Modular Multilevel Converter is found one of the leading technologies in Power Electronics & Control, its applications are very common in HVDC systems, FACTS (Flexible Alternating-current Transmission system), Variable frequency drives and Electric vehicles as well. The power quality of MMC is better and has lesser THD in comparison to conventional converters like 2-level converters with carrier-based modulation techniques. The MMC has been designed with high scalability and has high voltage and power capacity. Sub-module is an integral part of MMC which is built up as an identical and controllable part of it. This converter is also called a controllable voltage source (VSC). Researchers aim to come up with a detailed review of control methods and necessary operations applied to MMC-based systems for HVDC, particularly focusing to control the total harmonic distortions. Power converters use many modulation techniques, but the existing techniques contribute to a great part in switching losses. MMC up to 49 levels, by implementing the Nearest Level Modulation (NLM) technique, is robust and has less complexity for the systems like MMC-HVDC, and the levels control the total harmonic distortions. In this research paper, the reduction of THD by increasing the voltage levels in MMC is comprehensively evaluated. The simulation results in MATLAB/Simulink are used to examine and confirm the proposed control strategy for stable operation of MMC for HVDC application.

Bots are created to use the resources maliciously on World Wide Web. The misuse of the resources could be prevented by employing CAPTCHAs. Several types of CAPTCHAs are being used against the bots (robot) attacks but text-based CAPTCHA type is the most popular being very secured and easy to use. Latin language based text CAPTCHAs can be found ubiquitously on Internet but English text based CAPTCHAs are already decoded by many researchers. Thus, a novel Sindhi language based text CAPTCHA was proposed for regional websites where Arabic style script was utilized. This scheme offered two fold benefits: first, the proposed scheme could easily be understood by averagely literate person; second, this scheme paved a way for Arabic style OCR developers to understand Sindhi language specific features and facilitate Sindhi text recognition in future. A survey was also conducted to analyze the usability and strength of proposed CAPTCHA.

The Children's Forum is a forum for children's participation in development that bridges children's aspirations to the government. Child-friendly Cities/Districts aim to ensure the fulfillment of children's rights in a city/district. Both were formed by the Ministry of Women's Empowerment and Child Protection, so their existence is interrelated with each other. In Banyumas Regency both have been formed, so that with the presence of the Banyumas Children's Forum, participation can be analyzed as an effort to create a Child-friendly City in Banyumas Regency. This study aims to find out how the participation of the Banyumas Children's Forum in realizing Child-friendly City in Banyumas Regency is viewed from the perspective of multi-stakeholder partnerships using descriptive qualitative research methods. The selection of informants used was purposive sampling technique. Collecting data using interview, documentation and observation methods and data analysis methods using interactive analysis methods. The results showed that the Banyumas Children's Forum was formed by a Decree of the Banyumas Regent, fostered by the Banyumas Regent, and facilitated by the facilitators. However, the relationship between the facilitator and the Banyumas Children's Forum has not been closely intertwined because the task of the facilitator is conditional if the Children's Forum needs assistance. For the Child-friendly City program, it is the responsibility of all stakeholders, including the Banyumas Children's Forum which is included in the Banyumas Child-friendly City Task Force. The Banyumas Children's Forum is included in one of the institutional cluster indicators, which are responsible for realizing Child-friendly City. Therefore, to help realize a Child-friendly City, a Children's Forum has now been formed in 27 sub-districts throughout Banyumas, and it is being targeted to establish a Children's Forum in all villages. The activities of the Banyumas Children's Forum are monitored and evaluated directly by the Banyumas Regent as the supervisor and the Head of the Section for the Fulfillment of Children's Rights of the DPPKBP3A.

Published: September 2021

Correct identification of substances is essential to understand drug use and trafficking trends and guide measures for harm reduction and treatment. Two steps are needed to verify the nature of a substance properly: a presumptive test and a confirmatory test. There are presumptive tests which presents deficiencies, such as providing false-positive and false-negative results. Confirmatory tests are more reliable, but they are more expensive. With the appearance of New Psychoactive Substances (NPS), identifying and characterizing illicit substances has become more challenging. This paper focuses on presenting information about NPS characteristics and analysis. For this purpose, we have reviewed the literature to address the main aspects of five groups of NPS: amphetamine-type stimulants, synthetic cannabinoids, N-methoxybenzyl-methoxyphenylethylamine (NBOMe), synthetic opioids, and benzodiazepines. We present the main characteristics of each group and certain aspects of presumptive and confirmatory tests regarding these groups. Our findings show obstacles in developing methodologies that can correctly identify these substances, and problems can increase as new structures appear. This information can be helpful to drive research into identifying NPS and inform law enforcement and law practitioners about the main characteristics of each group and the main questions involving their identification.

This article presents data on the spread of horse helminth infestations in the Oymyakonsky region, postmortem examination of carcasses and organs of foals, as well as organoleptic, physical and chemical, microbiological studies of meat of foals slightly and strongly infested with helminths in a comparative aspect. According to the results of organoleptic studies of meat from weakly invaded foals meet the requirements of GOST -7269-79, GOST 32225-2013 and can be consumed as food without restrictions. Meat from heavily invaded animals differs from weakly invaded animals in organoleptic indicators. The meat has a red crust of dried carcass, folded, slightly moist, the muscles on the cut are moist, but don't leave a damp spot on the filter paper, expressed red color. The consistency of the muscle is tight, elastic, the dimple formed by pressing with the finger is slowly smoothed out. The smell of the meat is peculiar to that of foals. The fat is soft, slightly sticky and yellowish. The broth is cloudy, with flakes. Physico-chemical investigations showed that meat samples from weakly invaded foals meet the requirements of normative documents GOST R-51478-99, GOST-23392-78. During the comparative evaluation of the meat of weakly invaded and heavily invaded, the following indicators were established: peroxidase reaction - "positive", aminoammonia nitrogen content - 0.84, pH - 5.8. When adding copper sulfate solution to the broth under study, insignificant flakes appeared, while maintaining broth transparency - the reaction is "doubtful". In heavily invaded foals, meat quality does not meet GOST: peroxidase reaction is "negative", reaction with copper sulfate is dubious, meat broth is turbid, with flakes; aminoammoniacal nitrogen content is 1.4, pH - 6.2. The results of microbiological investigations of the meat of weakly invaded foals meet the requirements of normative documents GOST-32031-2012, GOST-10444.15-94. Detected in the meat of heavily invaded foals BSCP (coliforms), KMAFANM (coliforms) - 8*103, indicating that the meat obtained from heavily invaded foals on microbiological indicators, the established standards do not correspond. Consequently, the indicators of meat of weakly invaded foals correspond to fresh, good-quality meat, and the meat of heavily invaded foals is recommended for use in food after industrial processing.

It is known that wild animals and birds can be reservoirs and carriers of many infectious diseases of animals and humans. A cadastre of disadvantaged anthrax settlements was developed based on the study of epizootology, which will help optimize epizootological and epidemiological measures for the prevention of anthrax in animals (wild and domestic) and the population. We first identified yersinia (Yersinia enterocolitica and Yersinia pseudotuberculosis) from the material for shooting moose and roe deer living in the Central zone of Yakutia. Antibodies to the serogroups Leptospira Pomona, Grippotyphosa, and Icterohaemorrhagiae serogroups were detected in forest bisons exported from Canada to Yakutia for acclimatization. We developed a method for sampling frozen urine with snow at low temperatures (minus 10-50 ?С) to diagnose leptospirosis of wild animals and dogs, in places of natural habitat of wild mammals (without seizure and capture). The bactericidal effect of the probiotic strains of bacteria Bacillus subtilis TNP-3 and TNP-5 on the causative agent of leptospirosis of various serological groups has been established. The methods are protected by the Russian Federation patents for the invention. There was marked disease and mortality of roe deer from salmonellosis caused by Sal. abortus equi. There has been established the circulation of viruses of infectious rhinotracheitis, diarrhea in the deer population of the Arctic regions, the causative agents of which may be migratory birds and animals of the disadvantaged settlements. In the period of intensive exploration of Actica, climate warming and changes in the fauna, the migration routes of wild animals and birds, growing threat of zoonoses it is necessary to conduct large-scale monitoring of infections, especially viral diseases.

The parasitic disease Dirofilariasis has been detected in Central Yakutia for the last 3 years and deserves the closest attention from researchers and practicing veterinarians. In dogs infected with the nematode of the genus Dirofilaria and infected with in rural (suburban) dogs, the main pathomorphological changes were localized in the heart and were represented by atrophic, dystrophic and necrobiotic processes. In addition, the products of nematode metabolism led to the appearance of circulatory disorders. First of all, the researchers paid attention to the study of blood smears, a study of the microfilariae found in the smears. The authors also examined guard dogs that died from this disease, and not a complete examination of organs and tissues during the autopsy of the heart, luvers and parenchymatosis organs, sexually mature dirofilariae were found in the heart of the dissected fallen dogs. Subsequently, diagnostic methods were used to study peripheral blood, and live Microfilariae larvae were found. As the authors of the article note, cardiac Dirofilariasis subsequently had a destructive effect on red blood cells - red blood cells, and was observed in the development of Hemoglobinemia, Hemoglobinuria, in some cases leading to liver and kidney failure. On the part of the respiratory system, there were also characteristic clinical signs of chronic dry cough, difficulty breathing and shortness of breath, the detection of foci of wheezing in the lungs. During the disease, the animals had the development of pulmonary Thromboembolism characterized by the occurrence of fever and the release of sputum with blood. In dirofilariasis, the authors observed a fatal outcome, the corpses of the fallen animals were opened for examination of organs and tissues to detect nematodes.

Today feeding disorders (deficiency of crude protein and limiting amino acids), the use of feed contaminated with microscopic fungi can lead to immune depression. When feeding dysfunctional feed, the live weight gain of young animals and fattening pigs is reduced by 10-90%, depending on the balance and completeness of the rations in terms of nutrients. The article assesses the degree of contamination of feed with microscopic fungi and studies the effect of eliminating the deficiency of crude protein, lysine and methionine on the health status and weight gain of laboratory rats when feeding moldy wheat grain. A balanced for essential amino acids feed allows reducing the stress of the body's defense system from the negative effects of saprophytes. An experiment was carried out on 200 (10 groups, n = 20) weaned rats of the Wistar line in order to comparatively study the consequences of feeding the diets containing wheat grain contaminated with fungi of the genera Aspergillus and Penicillium, deficient and balanced to the norms of the requirement for crude protein and two essential amino acids - lysine and methionine. The number of micromycete reaches 109 CFU (spores) in 1 gram of feed. These molds are dangerous because of the possibility of their spores entering the body of animals and germinating in the lungs, liver, kidneys, heart, intestines, reproductive organs, and muscle tissue. Once in the blood, mold spores spread throughout the body. A complete zootechnical analysis of grain was carried out in the toxicology laboratory using the methods of zootechnical and biochemical analyzes of feed, livestock products and metabolic products. The negative effect of microscopic fungi on the health indicators of white rats is less pronounced with a balanced diet for essential amino acids. A decrease in the tension of immunity, expressed in a decrease in T-cell deficiency and activation of phagocytosis, was determined. The average daily gain on the contaminated feed decreased by no more than 20%, while the gain on the contaminated diet was 50-60% lower.

Modern fish farming having intensive forms of farming provides for feeding fish with artificial feed, fertilizing ponds and compacting fish planting in nursery, finishing and wintering ponds. This leads to close contact of cultivated fish and, in this regard, favorable conditions for the pathogens accumulation in ponds, the distribution of infectious and invasive diseases. Invasive diseases are a significant danger among diseases including pond fish dactylogyrosis. Dactylogyrosis are monogenetic suckers, parasites with a direct development cycle, live on the fish gill filaments, belong to conditionally pathogenic parasites and pose a serious danger to young fish. Despite a fairly complete study of the biology of carp dactylogyrid, a number of questions regarding the formation of the parasitofauna of these young fish in the early stages of development - the most vulnerable period of their lives - remain little covered in the literature. The work presents data on the Dactylogyrus types found in young carp in the nursery ponds of the Orenburg region, the invasion extensiveness and intensity. 4 species of monogenetic suckers have been found: Dactylogyrus vastator, Dactylogyrus extensus, Dactylogyrus achmerowi, Dactylogyrus anchoratus. Among the four species of Dactylogyrosis, only two species, Dactylogyrus vastator and Dactylogyrus extensus, were found most often and from an early age, two other species were found in older fish, 20 and 25 days of age with little invasion extensiveness and intensity.
