Diseño conceptual de un receptor solar para generar vapor de agua en concentradores parabólicos de disco
Authors: Martínez Carrera Carlos Sixto , Clemente De La Cruz Wuilber
Published: April 2022

La generación de energía masiva requiere gestionar grandes cantidades de vapor de agua, debido a que se tiene que introducir calor que permita elevar la temperatura por encima de los 1000 °C para generar vapor sobrecalentado capaz de mover generadores de electricidad; por ejemplo; la tecnología de los concentradores parabólicos de disco. En ese sentido, todavía no está lo suficientemente madura, pero es prometedora, debido a que los estudios han mostrado que el sistema de colector con disco parabólico es más eficiente, estable, predecible y confiable que otros sistemas, porque concentra la energía solar en un receptor que asimila y luego ofrece la posibilidad de almacenarla para posteriormente seguir utilizándola en más o menos 7 horas, lo que no se puede decir de otros sistemas no previstos para el almacenamiento de energía o con depósitos de energía altamente contaminantes, como es la energía fotovoltaica. Se ha propuesto el receptor solar junto con su sistema de almacenamiento, porque es donde se gestiona toda la energía concentrada y donde se determina la eficiencia de todo el sistema, es un proceso crítico; el objetivo, ha sido desarrollar conceptualmente una propuesta óptima tomando en cuenta materiales, condiciones y configuraciones que han sido estudiadas; concluyendo que son ventajosos. Todo esto, hecho mediante la metodología del diseño VDI 2221, ha ayudado a ordenar el proceso y conseguir los datos apropiados. Se ha obtenido el diseño de un sistema conceptual más óptimo de acuerdo a las informaciones más recientes, consiguiendo la mejor eficiencia, la configuración más óptima y no perdiendo de vista la duración del sistema, evitando el estrés térmico y evitar, en lo posible, materiales con alto índice de huella de carbono.

PT. Pusri utilizes Musi River water as a source of process water. Colloidal particles suspended in Musi River water cancause blockage and build-up of scale on pipes and process equipment. Therefore, a good coagulation process is needed to reduce the content of colloidal solids suspended in water by using a coagulant. Coagulants that are often used for water treatment include ACH, AS, and PAC. The objectives of the study are to assess the Effectiveness and to optimize the usage of the coagulant ACH, AS, and PAC on decreasing the turbidity of Musi River water sample as a raw water in utility unit of PT. Pusri. The coagulation process was carried out by varying the concentration of each coagulant and adding 0.1 ppm of coagulant aid for all samples. Fast and slow stirring was carried out each at a speed of 150 rpm 30 rpm for 10 minutes. From the experiments conducted, it was found that the most efective coagulants to be used were ACH and PAC with the addition of a smaller coagulant dose of 12 ppm to achieve the standard water quality used at PT. Pusri. Meanwhile, the use of AS has higher eficiency when compared to ACH and PAC because it is more cost efective.

Authors: Baah-Duodu Samuel
Published: April 2022

Ageing car tyres are a hidden hazard and recipe for road accidents. Many vehicle users and their cohorts seem unconcerned and ignorant about tyre profile and its implications on human lives and livelihood. This study reviewed car users’ and vulcanizers’ comprehension of basic arithmetic of vehicle tyre profile to instigate best practices as well as instil proper maintenance culture. Out of 307 participants, purposive and convenient sampling were employed to select 292 vehicle users and a snowball to contact 15 vulcanizers. Results after a short interview analysis revealed that car users are aware of tyre inflation pressure and could identify the rim diameter of car tyres. Meanwhile, a significant number of users couldn’t tell where to locate their vehicle tyre specification details on their cars and were also unable to interpret tyre profiles including; tyre life cycle, tyre blend, tyre speed rating and load index. Although the majority of the vehicle users carried spare tyres, most of them do not check the conditions of their spare tyres until they are in need. Responses from vulcanizers revealed that most vehicle users do not bother about tyre expiry dates but rather prefer tyre fixing to tyre replacements. It is recommended that the Leaders of Transport Unions of commercial vehicles need to ensure proper load weight of vehicles before setting off from their terminals. Drivers and Vehicle License Authority (DVLA) needs to ensure healthy tyre condition before issuing roadworthy certificates. National Road Safety Authority (NRSA) must maximize sensitization campaigns towards proper tyre maintenance practices to reduce tyre failure accidents.

Bacterial load determination of poultry feed with seasonality effect in Karachi, Pakistan.
Authors: Iram Shajeela , Khawaja Tabinda , Mehmood ul Hassan  , Khan Muhammad Jawad , Abbas Tanveer
Published: April 2022

Background: The escalating rate of food-borne diseases via poultry feeds necessitates the characterization of the pathogens to reduce the health risk factor for humans and animals. The poultry feed microbial analysis help to control food-borne illness. In addition, the knowledge about seasonal effects on microbial growth helps the manufacturers to take precautionary measures in alarming months to maintain the standard quality of poultry feed.

Methodology: This study was designed to identify and enumerate bacteria and their seasonal variation. Total feed samples (n=204) were evaluated through traditional culture techniques, microscopic inspection, and biochemical properties. However, bacterial load was determined by using the total viable count.

Results: As a result, five genera, including Salmonella enterica (39.05%), Escherichia coli (22.48%), Bacillus subtilis (18.34%), Staphylococcus aureus (11.24%), and Streptococcus sp (8.87%), were isolated. The proportion of occurrence of the bacterial load was lowest in December-February (64.4%) and highest in June-August (96.2%). Whereas in September-November was (87.6%) and March-May (77.5%). On the whole, the total percentage of positive samples was 82.8%. Statistical analysis revealed that (9.9×10-8 cfu/g) was the highest viable bacterial count recorded from June to August. The presence of food-borne pathogens, especially S.enterica and E.coli, is bothersome. Moreover, June to August is considered the most troubling month due to the elevated level of contamination.

Conclusion: To evade microbial contamination, the microbiological security rules must be followed throughout the process of formulation and storage period, especially in sensitive hot and humid months of June to August. Also, standard inspection should be taken to control the dissemination of food-borne illness.
Antihyperlipidemic, hypoglycaemic and antioxidative potential of Juglans Regia (walnuts) in an experimental animal model of dietary hyperlipidemia.
Authors: Sangi Iqra , Shamim Mufzala , Khan Nazish Iqbal
Published: April 2022

Background: Cardiovascular diseases (CVD) are recognized as the world's primary cause of fatality, particularly in the developing countries. Stroke and ischemic heart disease have reportedly been the principal manifestations of vascular disease mainly because of the gradual increase in the incidence of the risk factors. In this aspect, the present study is planned to investigate the cardio-protective potential of Juglans regia (JR) (walnuts) consumption in controlling dyslipidemia. JR has notable therapeutic effects and, it has been used since ancient times for its anti-inflammatory, cardio-protective, and anti-bacterial properties.

Methodology: In this study, 32 age-matched females, Wistar albino rats of 5-6 weeks weighing 200 g, were selected and equally divided into four experimental groups. Group I was used as control, Group II was positively induced hyperlipidemia through a high-fat diet; Group III animals were fed normal rat chow along with 153 mg JR powder, and Group IV animals have also inducted hyperlipidemia through a high-fat diet incorporated with 153 mg JR powder/Kg for 15 days. Bodyweight changes along with daily diet consumption were measured on alternate days.

Results: In comparison to the control group, animals fed with a high-fat diet (Group II) showed a non-significant increase in plasma lipid profile, total cholesterol (TC), triglycerides (TG), and plasma high-density lipoprotein (HDL) levels. Group III and IV animals, after walnut powder supplementation, showed a significant decrease in lipid profile change in very Low-Density Lipoprotein levels (VLDL) of 10.3 ± 0.60 mg/dl and 12.27 ± 0.94 mg/dl together with nephron-protective & reno-protective enzymatic alterations. Histological analysis revealed signs of inflammation in high fat treated groups while well-maintained cardiac tissues within walnut treated groups, respectively.

Conclusion: Daily consumption of Juglans Regia (walnut) in the dosage mentioned earlier is beneficial in protectively modulating dyslipidemia, hyperglycemic, and oxidative tissue potential of high-fat diet consumption in an experimental animal model.

Authors: Farhan Muhammad , Ahmed Syed Farhan , Mithani Hammad , Aziz Wajahat , Nazim Syed Muhammad , Zia Muhammad Khurram
Published: April 2022

Background: Leading urology guidelines recommend intravesical chemotherapy and immunotherapy for non-muscle invasive bladder cancer (NMIBC) to reduce the risk of recurrence and progression. This study aims to evaluate the self-reported practices regarding intravesical therapy use for patients with non-muscle-invasive bladder cancer among urologists in Karachi. Methodology: In this cross-sectional study, a proforma-based survey was conducted between January and March 2018, in which printed questionnaires regarding adjuvant treatment options for NMIBC were administered and collected by primary investigators among urologists in leading institutions of Karachi. Results: Overall, 80% of respondents reported routine administration of single instillation of intravesical chemotherapy (SICA) after transurethral resection of bladder tumor (TURBT), and almost one-third of them (37.3%) give SICA within 6 hours inward. A quarter of respondents practice induction therapy routinely in low-risk BC using Mitomycin, whereas 76.5% in high-risk cases use Bacillus Calmette Geurin (BCG) as immunotherapy. Regarding the time duration of intravesical therapy installation, most of the urologists reported for 45 mins (49%) followed by 30 mins (29.4%), 2 hrs (17.6%), and 3 hrs (3.9%). Only 39% reported routinely using maintenance therapy with BCG for high-risk BC. As for BCG failure, 76.5% of participants reported radical cystectomy. Conclusion: Our survey results provide evidence of variation in practices among urologists and poor guideline adherence with the risk of under-treatment of patients with NMIBC. This requires joint efforts of all those involved in the treatment of non-muscle invasive bladder cancer to improve the quality of care.

This paper provides an overview of a transnational research project exploring the impact of the COVID-19 pandemic, and public health responses to it, on sexual and gendered politics. It sets out a framework for rethinking sexual and intimate citizenship during the COVID-19 pandemic, and draws on examples from India, Italy, Mexico and the UK to illustrate our analysis. We examine how the pandemic has impacted on the everyday negotiation of intimacy and highlighted material inequalities that impact on the lives of women and LGBTQ+ people. We argue that the pandemic has produced new faultlines between women and different groups of LGBTQ+ people, as well as amplifying existing tensions. In addition to identifying these faultlines, we explore the cracks opened by them which might reveal possibilities for new coalitions and alliances in relation to sexual and gendered politics.

Introduction: In the spirit of maintaining health and seeking medicine to cure a disease, the question of halal and haram still needs to be answered. This coincides with the words of the Prophet Muhammad SAW “Verily Allah does not make your healing in what He has forbidden you” (HR. Imam Bukhari). The purpose of this quantitative study was to determine the effect of religiosity, perception, knowledge, and attitudes of Muslim doctors on the use of halal drugs in Indonesia. Materials and methods: This quantitative research method with correlational type examines the relationship between religiosity, perceptions, knowledge, attitudes, intentions, and behaviors that are shared online using google form. Data was measured using a Likert scale. A five-point Likert scale was used for statements: Strongly Disagree: 1, Disagree: 2, Uncertain: 3, Agree: 4, and Strongly Agree: 5. The sample size used was 435 Muslim doctors. The data obtained were then processed using the SmartPLS 3.0 application. Results: The results obtained are that there is a relationship between the religiosity of Muslim doctors on perceptions so as to encourage intention so that there is a change in behavior in the use of halal drugs in Indonesia. In addition, there is a relationship between knowledge and attitudes so as to encourage intentions that cause behavioral changes in the use of halal drugs in Indonesia by Muslim doctors. In fact, every practice depends on the intention, therefore it is important to maintain the intention, which in this study is influenced by perceptions and attitudes so that charity will result in commendable behavior that is blessed by Allah SWT. In addition, there is also a need for education about halal drugs that are appropriate to be taught at the medical faculty of Islamic universities in Indonesia.

A inteligência artificial (IA) não se destina a substituir o médico, mas sim, a criar um fluxo de trabalho eficiente, ensejando tempo para as relações médico-paciente. No cenário em que o cirurgião e o paciente devem permanecer no centro da tomada de decisão, a IA proporciona um suporte de precisão para a tomada de decisão médica. Isso ocorre por meio da integração de diversas fontes de informação como fatores de risco do paciente, anatomia cardíaca, história natural da doença e custos hospitalares. Na cirurgia cardíaca, a inteligência artificial pode ser usada em três áreas principais: predição de risco cirúrgico, exames de imagem e realidade aumentada na sala de cirurgia. O sistema IA tem uma variedade de configurações/formulações, que vão desde aquelas que buscam responder um problema usando grandes conjuntos de dados, de modo a gerar uma estrutura nos moldes do raciocínio humano, até aqueles que tentam incorporar elementos do raciocínio humano, mas não exigem modelagem precisa dos processos humanos. Um dos braços da IA é o aprendizado de máquina (AM), que corresponde a técnicas de modelagem estatística e matemática que usam uma variedade de abordagens para aprender e melhorar automaticamente a previsão de um desfecho, sem programação explícita. Assim, redes bayesianas,random forest,deep learning e redes neurais artificiais, usam diferentes suposições e estruturas matemáticas para entrada de dados, e o aprendizado ocorre dentro do algoritmo.
