الجدل المستمر بخصوص التعريف العام للقدرة الكهربائية (الجزء الأول: دراسة مرجعية)
Authors: حشاد منصور , أبو عزة أسماء , المصراتي نادية
Published: May 2023

يعتبر موضوع التعريف العام للقدرة الكهربائية من المواضيع التي تثير جدلاً واسعاً، وهذا الجدل مستمر منذ تسعينيات القرن التاسع عشر إلى يومنا هذا. هدف هذه الورقة، في المقام الأول؛ تقديم دراسة مرجعية عن طريق المسح التأريخي، بتمييز ما يراه المؤلفون جزءًا من النقاط المفصلية الأبرز في تاريخ هذا الجدل المستمر، حيث أصبحت هناك "نظريات قدرة" تُسمى بأسماء مقترحيها، لا يلغي إحداها ما سواه بشكل قطعي وكامل، بل كأنها تعيش مع بعضها البعض في قطيع يتنافس أفراده على الزعامة فقط، كظاهرة غير مألوفة في العلوم الدقيقة.  في هذه الحالة من الريبة وعدم التيقن، كان من المهم أيضاً ذِكر المتفق عليه –على قِلته- ونطاق الاتفاق. في الورقة تم تقديم بعض الملاحظات الخاصة بالمؤلفين من بينها إضافة جدلية جديدة من قائمة المتفق عليه إلى قائمة المتخاصم عليه، استناداً على قانون تيليجن (Tellegen Theorem) لموازنة القدرة اللحظية. أيضاً تم تقديم مقارنات وملاحظات بخصوص بعض الجزئيات النقدية والحسابية والتشبيهية، مما نعتبره قيمة  بحثية إضافية للقيمة المرجعية.  الدراسة النقدية المتكاملة تحتاج لسلسلة من الورقات المرجعية. تعريف القدرة الكهربائية بالشكل العام –أي للدوائر الغير خطية بمنحنيات غير جيبية بفترة متكررة أو غير متكررة لأي عدد من الأطوار- أصبح موضوعٌ بالغ الأهمية وخصوصاً بعد الانتشار الواسع لأجهزة القدرة الإلكترونية في مجال إنتاج وإرسال واستهلاك الطاقة الكهربائية. الموضوع اليوم له عدة تيارات بحثية، من أهمها: التيار الأول هو تفسير الجانب المعرفي الفيزيائي للموضوع وهو بحثي صرف، والتيار الثاني هو قياسي تنميطي، والتيار الثالث يخص تصميم دوائر الترشيح سواء السلبية أو النشطة، وخصوصًا خوارزميات التحكم للمرشحات الفعالة. في هذه الورقة سيتم التركيز على الجانب الفيزيائي الرياضياتي لمفهوم القدرة الغير فعالة. مؤخراً هناك تيار بدأ يظهر، يعتمد الوصف المجالي باستخدام معادلات ماكسويل (Maxwell's Equations) و متجه بوينتنغ (Poynting Vector) كمحاولة لسبر حيثيات الخلاف.

O líquen plano oral (LPO) é um processo inflamatório crônico mediado por células T que acomete a mucosa bucal ou pele, com incidência maior em mulheres adulta, tendo uma prevalência global baixa em torno de 1,01%. Normalmente assintomáticos, tem aspecto clínico diverso, podendo se apresentar em forma de bolhas, placas, pápulas, atróficas, erosiva ou reticular. Em alguns casos pode se apresentar de forma sintomática, com sensação de queimação e desconforto. Para um diagnóstico assertivo do LPO, é necessário o exame de biopsia, sendo os aspectos histopatológicos caracterizados por hiperqueratose, cristas epiteliais ausentes ou hiperplásicas, degeneração hidrópica da camada basal, presença de corpos hialinos e infiltrado inflamatório crônico na camada epitelial basal e camadas adjacentes, sendo em alguns casos necessário diagnóstico diferencial de outras lesões brancas da cavidade bucal. O objetivo do presente estudo é relatar um caso clínico muco-cutâneo de líquen plano acometendo paciente do gênero masculino, leucoderma, sexo masculino, 58 anos, onde a condução do tratamento e a evolução da lesão foi decisiva para se firmar o diagnóstico diferencial de líquen plano da leucoplasia. Os autores concluem que o diagnóstico diferencial de lesões brancas da cavidade bucal nem sempre é fácil, exigindo do profissional um conhecimento profundo das patologias e o discernimento de fazer o diagnóstico diferencial de lesões com similaridades, de modo a diagnosticar e tratar as lesões de forma adequada.

El presente trabajo relata una experiencia de taller online de arteterapia y apoyo emocional, desarrollada durante la pandemia, a usuarios cuya condición de salud mental se había complejizado en el contexto sanitario y quienes fueron derivados por el equipo psicosocial del área de salud mental del Centro de Salud Familiar (CESFAM) Santa Anselma, ubicado en la comuna de La Cisterna de la ciudad de Santiago de Chile. De los once usuarios derivados sólo siete pudieron participar inicialmente del taller, cuatro mujeres y tres hombres.
La metodología utilizada fue participativa, donde las arteterapeutas eran facilitadoras de los encuentros grupales. Se realizaron un total de diecisiete sesiones de dos horas cada una -las primeras doce con una frecuencia una vez a la semana, mientras que las últimas cinco, desde agosto a diciembre del año 2021, una vez al mes, iniciando con ello el proceso de cierre.
El taller tuvo muy buenos resultados y adherencia por parte de los participantes. Dentro de los resultados positivos se destacan: la creación de una red de apoyo entre los participantes que posibilitó bajar la intensidad del sentimiento de aislamiento social. A su vez, permitió crear un espacio seguro que posibilitó a los participantes expresar los sentimientos y emociones vivenciadas durante este período. Por otra parte, los desafíos que se presentaron durante su desarrollo destacan la adecuación del encuadre arteterapéutico a la modalidad online, como también la escasez y poca diversidad de materiales de arte.

Para um bom desenvolvimento inicial das culturas olerícolas, as sementes devem ser semeadas em substrato que atenda todas as suas necessidades iniciais. Para isso, este deve apresentar características como: boa aeração e estrutura, boa capacidade de retenção de água, boa drenagem, dentre outros fatores. Nesse sentido, o objetivo do trabalho foi avaliar a influência de diferentes substratos na emergência e no desenvolvimento inicial de plântulas de Curcubita maxima L. em casa de vegetação, no município de Sumé-PB. O experimento foi conduzido no viveiro de mudas do Laboratório de Ecologia e Botânica (UFCG/CDSA). O delineamento utilizado foi inteiramente casualizado com cinco tratamentos. Os substratos utilizados foram: areia (T1), esterco ovino (T2), terra (T3), areia+ terra + esterco (T4) e terra + esterco (T5). Foram avaliados índice de velocidade de emergência (IVE); comprimento de plântulas (CP) e massa seca das plântulas (MS). De acordo com resultados obtidos, constatou-se que os substratos influenciaram em todos os parâmetros estudados. Assim, o substrato terra e esterco (T5) foram considerados como o mais eficiente para a emergência de sementes e massa seca das plântulas, enquanto o substrato areia+terra+esterco (T4) foi o que proporcionou uma maior velocidade de emergência e comprimento de plântulas de C. maxima, em condições não controladas no município de Sumé-PB . A temperatura é um dos fatores climáticos mais importantes para o cultivo das cucurbitáceas, que se adaptam bem a zonas quentes e semiáridas, com temperaturas de 18º a 30ºC, sendo assim esta cultura tem um bom desempenho em nossa região já que dispomos de temperaturas elevadas durante o ano inteiro.

Authors:   , Araújo Macena Romildo
Published: May 2023

Nos ambientes áridos e semiáridos do mundo encontramos diversas espécies de cactáceas. No Brasil, podemos destacar o bioma Caatinga, onde são encontradas maioria das espécies de cactáceas, muitas delas endêmicas. Podemos destacar as espécies Cereus jamacaru DC,” e Pilocereus gounellei (A. Weber ex K. Schum.) Bly. ex Rowl, As duas espécies são importantes recursos alternativos, sendo utilizados para diversos fins. Estudos sobre a germinação de cactáceas frente aos fatores abióticos são essenciais, pois ajudam a compreender sua morfologia e fisiologia contribuindo para conservação e preservação nos ambientes áridos e semiáridos. Desta forma, o presente trabalho tem por objetivo avaliar a resposta da germinação de C. jamacaru e P. gounellei submetidas a diferentes gradientes de temperatura e salinidade. Os parâmetros de germinação utilizados foram: tempo médio de germinação (TMG), germinabilidade (G%), índice de velocidade de germinação (IVG) e índice de sincronia de germinação (E). Nos testes de germinação foram contrastados seis tipos de temperaturas (15, 20, 25, 30, 35 e 40 ºC) e seis concentrações salinas de NaCl p/v (0, 16, 25, 33, 41 e 49 mMol.L1 ) sob fotoperíodo de 12h. O experimento foi conduzido em um delineamento inteiramente casualizado (2 espécies x 6 temperaturas x 6 salinidades), resultando em 36 tratamentos com 6 repetições de 300 sementes cada, sendo 150 para C. jamacaru e 150 para P. gounellei. Os resultados, apresentados no presente estudo, mostraram diferenças, para todos os parâmetros de germinação, entre as espécies, temperatura e interação espécies x temperatura (p < 0,001). A espécie C. jamacaru mostrou maiores valores de germinação, mas com maior sensibilidade em temperaturas mais extremas (15, 35 e 40 ºC). Enquanto, P. gounellei, apesar de apresentar menores valores de germinação, mostrou ser mais resistente as maiores temperaturas (35 e 40 ºC), apresentando bons parâmetros de germinação. As repostas germinativas de C. jamacaru e P. gounellei parecem demonstrar uma larga tolerância à salinidade. Enquanto, para temperatura C. jamacaru, apesar de mostrar maior poder germinativo, mostrou menor tolerância às temperaturas mais extremas (15, 35 e 40 ºC), diferentemente de P. gounellei que apresentou maior resistência aos extremos de temperaturas.

Coronavirus disease 2019 (COVID19) is the recently reported disease caused by novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID19 spreads among population through the close/direct contact and nasal droplets when an infected person sneezes, coughs, talks or breaths. On an average, COVID19 infected patient develops clinical symptoms 5-6 days after the infection and some develops symptoms even after 14 days of infection. Detailed study on the symptoms shown by COVID19 patients can help in identifying individuals so that proper identification and isolation of patients can be done and transmission of virus can be reduced significantly. In this study, a total of 99 (66 males and 33 female) COVID19 infected symptomatic patients without any comorbidities were included. Nasopharyngeal and oropharyngeal swabs were used for the collection of samples from the suspected patients to extract total RNA and perform real time PCR for the detection of genetic material for SARS-CoV-2. Samples with Ct value ≤ 36 in case of Orf1ab gene and E gene with good sigmoidal curve were reported as positive for novel SARS-CoV-2. Fever, shortness of breath, dry cough and cough with sputum production persisted for longer timer and were more common symptoms reported by the COVID19 infected patients. In conclusion, understanding of the clinical symptoms shown by COVID19 infected patients can help in identification and isolation of patients so that transmission of virus can be reduced significantly.

Since Edward Jenner’s creation of vaccine 200 years ago, which been serving as a boon to mankind till today and being benefited by vaccination. Childhood vaccination is done for infectious disease like Polio, measles, rubella etc. Apart from these childhood vaccinations, vaccine for communicable diseases also been developed which is leading to improvement of quality and standard of life. In 20th century there are many modern methods and improvised methods for vaccine development and immunisation. With all improvised technique they need monitoring during their manufacture. Introduction of any new vaccine to the market requires registration, approval, licensing etc. Individual country regulations should be followed, guidelines to be adhered to and submit all required documents. Upon approval they can market their product with all legal rights. In Australia, Therapeutics Goods Administration (TGA) regulates the approval vaccines and medicines and some lifesaving drugs. TGA has introduced two new pathways for rapid approval for life saving drugs for emergency use. The main objective of rapid approval process is to make sooner available of drug sooner than the usual regulatory process.
Are 5HT7 Receptors Possible Target for Multiple Sclerosis?
Authors: Justin Antony , Murugan Deepthi , Basavaraj Meghana , Prem Kumar Ashwini
Published: May 2023

Multiple sclerosis (MS) is a neurological condition with a complicated autoimmune component that mainly affects women in their forties and fifties. The disorder appears in several forms, ranging from episodic somatosensory impairment to progressive and irreversible central nervous system (CNS) injury. The fundamental cause of this disorder is lack of serotonin (5HT), a neurotransmitter with numerous immune effects. Decreased 5-HT levels or synthesis have also been related to increased proinflammatory cytokines in the CNS. Among several other proinflammatory cytokines, two prototypic pro-inflammatory cytokines, interleukin-1 (IL-1β) and tumor necrosis factor (TNF-α) have been identified as primary effectors of neuroinflammation's functional effects on neurodegeneration.TNF-α is a pleiotropic cytokine that regulates homeostasis, immunity, and inflammation and IL-1β is also a cytokine with neuroimmunological and neurophysiological functions. MS patients are usually on drugs that change the serotonergic system, because of increased clinical comorbidities and proven serotonin deficits. Several studies have shown that higher 5-HT levels have anti-inflammatory and immune-modulating properties, which could help to delay the progression of the disease.

The Influence of Government Policies and Economic Factors on the Growth of Entrepreneurial Activities in Khartoum, Sudan
Authors: Babiker Yusra H. M. , Timan Elfadil , Ali Malik Elnaeem Mohammed
Published: May 2023

Understanding the influence of government policies and economic factors on the growth of entrepreneurial activities is considered a step towards successful entrepreneurship in Sudan. The goal of this article is to explore the government policies and economic factors which influence the growth of entrepreneurial activities in Khartoum Locality, Khartoum State, Sudan. The research was conducted on a sample of 400 national potential entrepreneurs, and data were collected using a structured questionnaire and personal interviews. Respondents are asked 43 questions to assess their perception of the main factors influencing the growth of entrepreneurial activities. The study adopted an analytical descriptive methodology whereby the data were processed by the statistical package for social sciences (SPSS). Percentages, frequencies, and hypothesis tests were used to analyze data. The study revealed that one major problem for entrepreneurs is the high tax fees which hinder the progress of entrepreneurship. Also, not everyone could get a business license. Furthermore, they tend to enter the field of entrepreneurship due to limited government employment opportunities. Entrepreneurs considered entrepreneurship as one of the best solutions for their unemployment problems. Through business incubators, entrepreneurship may expand and flourish in Sudan. Microfinance programs may contribute to the development of entrepreneurial activities, although entrepreneurs face obstacles in such programs, for example, the inability to pay back and the failure of their projects. Credit and loan policies towards entrepreneurs in commercial banks in Sudan need to encourage new ideas and innovations. Self-finance and family finance are important sources for getting money to execute entrepreneurial activities. The study recommends that government agencies should provide financing facilities for entrepreneurs in a way that may contribute to the development of entrepreneurial activities. The government of Khartoum State needs to concentrate more on entrepreneurial training as it is necessary to improve entrepreneurship. It is very important to decrease tax fees because it is a large obstacle facing entrepreneurs. The authorities must facilitate the provision of business licenses to those who have the ability and desire to establish a business. Commercial banks need to strengthen microfinance programs to help entrepreneurs to enter the entrepreneurship field.

A field experiment on resource-use efficiency of common bean (Phaseolus vulgaris L.) as influenced by tillage and residue management under temperate Kashmir valley was conducted at Faculty of Agriculture, Shere- Kashmir university of Agricultural Sciences & Technology of Kashmir, Wadura during kharif 2018. The site of the experiment was ideal for common beans due to its silty clay loam texture that provided a medium level of soil organic carbon and readily available primary nutrients. The experiment was conducted in randomized block design (factorial) comprising of four type of tillage systems namely conventional (CT), rotary (RT), minimum (MT), and zero tillage (ZT) as the first factor. Two residue management practices, i.e., no residue (NR) and application of brown sarson residue (SR) were supplemented to all the tillage treatment as the second factor. The results revealed that seed yield in zero tillage was comparable to conventional tillage. Seed yield and biological yield was also increased in residue application. Resource use efficiency like nutrient-use efficiency and irrigation water-use efficiency was significantly higher with rotary tillage followed by conventional tillage. Contrary to nutrient use efficiency and irrigation water use efficiency, energy-use efficiency was significantly higher with zero tillage and rotary tillage irrespective of residue management. Residue application also increased the resource use efficiency of common bean. The effect of zero tillage and residue application on resource-use efficiency would advance after some extended period of the treatment application.

Published: May 2023

‘New Delhi’ capital of India is under immense pressure to sustain increasing population and to cope up with urbanization. It has urban forests or ridges, which aids the Delhi’s healthy lifestyle by balancing ecosystem. To assess the forest health the species composition, density, basal area, IVI, diversity indices, regeneration status of tree species were evaluated. Three sites namely Kamla Nehru Ridge (KR), Central Ridge (CR) and Southern Ridge (SR) were selected. A total of 51 tree species belonging to 21 families were reported. Species richness varied for trees (20-37), saplings (5-20) and seedlings (5-11). Densities ranged between (517-1043 Individuals/ha) for trees, saplings (133-470 Individuals/ha) and seedlings (53-273 Individuals/ha) respectively. Species diversity ranged between for trees (2.3-3.3), saplings (1.4-2.2) and seedlings (1.5-2.1). Total basal area varied from 4.87 to 22.94 m2/ha (trees), 0.26 to 0.49 m2/ha (saplings) and 0.17 to 0.02 m2/ha (seedlings). Maximum species (20-70%) showed ‘no’ regeneration whereas, (30- 50%) showed ‘poor’ regeneration and only Acacia leucocephala showed ‘fair’ regeneration in SR. It was observed that Prosopis juliflora was the dominant species in all three sites; it is an exotic species which hinders the understory growth. All over regeneration status of Delhi’s urban forest was found ‘poor’, which is a matter of concern. For balance environment and for proper inflow of ecosystem services provided by urban forest to sustain healthy lifestyle in city, it is necessary to implement proper strategies for conservation and maintenance of these forests.

Valan kakri is an underexploited vegetable and has great potential for genetic improvement through systematic approach. In this study, variability parameters were evaluated in 30 genotypes of Valan kakri collected from different villages across Udaipur during September 2019 and morphological studies were done at Rajasthan College of Agriculture, Udaipur. The genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were highest for fruit length (34.48%, 35.43%) followed by fruit weight (61.64 % and 62.04). Estimates for heritability (Broad sense) ranged from 69.70% for seed cavity breadth to 99.24% for acidity of fruit. Traits like fruit length, fruit weight, seed cavity length, acidity of fruit, ascorbic acid content had high GCV, PCV and heritability along with high genetic advance as percentage of mean. Therefore, selection can be effective for these traits in crop improvement programme.

50 Years of the Clean Water Act: Can We Sustain Its Success
Authors: Yoder Chris O.
Published: May 2023

The effectiveness of the Clean Water Act in mandating the abatement of gross pollution by setting technology standards for categories of municipal and industrial point sources is well documented. Still, the CWA has not been modernized to update water quality standards, it has not readily employed the latest science, and the benefits have not been documented nearly well enough. Increasingly insidious attempts to undermine its continued effectiveness have arisen over the past 10–15 years mostly at the state level.

Background: In this research, premenopausal women with HR-HPV infections and atypical cervical smears were compared by age. Materials and method: 200 regularly screened women between the ages of 36 and 60 had a cervical smear and HPV detection. Demographic, behavioral, and medical data were gathered by telephone surveys. Descriptive analysis was used to look at the connection between HR-HPV infections and cervical aberrations by age.  Results: Age significantly decreased the number of cases of cervical abnormalities, HR-HPV, and human papillomavirus, as well as the correlation among these disorders. In younger females with abnormalities, HR-HPV detection was 60%; however, it steadily decreased to 30% in "50-54-year-old" women, without abnormalities found in 55-60 years old females. Different relationships between HR-HPV infection and anomalies remained found in females over 45, a pattern not observed in females who were young by age. Conclusion: Age had no effect on several kinds of low-grade and severe anomalies, but we saw a decline in the agreement among cytological results and HR-HPV tests.

The retrospective study was conducted in the Department of Ophthalmology, Nishtar Medical Hospital, and Bakhtawar Amin Trust Hospital from January 2022 to January 2023 to evaluate risk factors and surgical approach for posterior dislocation of the intraocular lens into vitreous requiring pars plana vitrectomy. A total of 30 eyes of 30 patients (20 male and 10 female) were included in the study. Standard PPV vitrectomy was performed in all patients. The Iris fixation technique was used in patients having a 3-piece lens design. A sclera fixation technique was performed to secure the lens and prevent it from falling onto the retina. IOL (Intra-Ocular Lens) was exchanged in eyes in which it was previously damaged. Results showed that in 28 (93.3%) eyes, the original lens was conserved and positioned on the scleral wall, iris, or both. The existing lens could not be preserved in 2(6.6%) eyes. 92.1% of cases had a single risk factor for IOL dislocation. After surgery, uncorrected visual acuity (UCVA) improved from 20/400 on the initial visit to 20/80 on the final (P=0.001). UCVA remained unchanged in 3 (10%) patients and improved in 27 (90%) patients. It can be concluded that the incidence of posterior IOL dislocation has been increasing. Intravitreal substance injections, myopia, and previous vitrectomy are the major risk factors. In most cases, the existing lens can be preserved and secured in the posterior chamber through pars plana vitrectomy.
