Assessment of heavy metals in eggplant fruit from urban and rural areas of bangladesh

Dietary intake of contaminated food with heavy metals may cause severe risk for the human health. Heavy metals affect adversely a human health. The current study assessed the concentrations of heavy metals including Cu, Zn, Pb and Ni in eggplant (Solanum melongena L.) of urban and rural areas in Bangladesh. The experimental samples of fresh eggplant fruits were collected from six local markets in Jashore, Bangladesh, and the tissues were extracted with nitric acid and hydrogen peroxide. Trace elements in eggplant fruits were estimated with atomic absorption spectrophotometer. Obtained result show that Heavy metal concentrations were high in the urban areas compared to rural areas. Heavy metals in the eggplant fruits of rural and urban areas were: Pb (2.74-18.64), Cu (10.20-67.16), Ni (46.63-148.46), and Zn (86.65-148.73) mg.kg-1 respectively. The concentrations of Pb, Ni and Zn in eggplant were at an excess of safe limits according to the Food and Agriculture and World Health Organizations. While, Cu was lower than the maximum safe limit. The present study concluded that growing eggplants in Jashore areas are heavily contaminated with Pb, Ni and Zn that would be hazardous for consumer’s health. The result of this study will be beneficial for the agricultural policy makers in Bangladesh to take appropriate action and reduce the heavy metal toxicity among fresh food products.

Hemolytic uremic syndrome: an updated review

Hemolytic uremic syndrome (HUS) is a microangiopathic thrombotic disease, which is classified into atypical, typical, and secondary types. Thrombocytopenia, acute kidney failure, and hemolysis are the main features of HUS regardless of its type. Infection with Shiga toxin-producing Escherichia coli causes typical HUS, and gene mutations trigger atypical HUS, while secondary HUS is associated with bone marrow transplantation, autoimmunity, cancer, and other diseases. New insights into the pathogenesis of HUS have emerged over the past decades, suggesting an important role of the complement system in disease pathogenesis, which has been reinforced by the efficacy of plasma exchange and monoclonal antibodies in its treatment. In this review, we performed an updated review of HUS with a focus on understanding its pathogenesis.

Hybrid cryptography algorithms for enhanced adaptive acknowledgment secure in manet

The mobile adhoc network is a group of mobile nodes without having the fixed infrastructure. Due to the infrastructure less network and distributed nature, make mobile adhoc network susceptible to malicious attackers. So, we use an intrusion detection system called Enhanced Adaptive ACKnowledgement (EAACK) especially for mobile adhoc networks. Based on the digital signature algorithm (DSA) and RSA the EAACK is designed. To enhance the strength of the security in the mobile adhoc networks, we introduce an innovative approach called Hybrid Security Protocol that provides integrity, confidentiality and authentication. This Hybrid Security Protocol consists of Cryptography based on Elliptic curve, Dual-RSA algorithm and Message Digest MD5. Encryption is achieved by using Elliptic Curve Cryptography, Dual-RSA algorithm for authentication and MD-5 for integrity. By using a combination of both symmetric and asymmetric cryptographic techniques, we achieve better security with integrity.

Prevalence of tuberculosis in shabwah governorate, yemen: a cross-sectional study

Background: There is a lack of data on current tuberculosis (TB) burden in Shabwah Governorates in Yemen. This study aimed to investigate the prevalence, epidemiology, and outcomes of TB disease in Shabwah Governorate, Yemen. Materials and Methods: This cross-sectional study was conducted at the National TB Program (NTP) Center in Ataq City, Shabwah Governorate, Yemen. The study involved TB patients of different ages who were notified at the center between January 1, 2021, and December 31, 2021. Results: We involved a total of 123 new active TB cases, including 86 (69.9%) with pulmonary TB (PTB) and 37 (30.1%) with extrapulmonary TB (EPTB). The total prevalence of TB disease during the year 2021 was 14.5 new TB cases per 100,000 population, while the median age of the study population was 34 years. The majority of the cases (23.6%) belonged to age group 15–24 years. There was a slightly higher preponderance of males 54.5% (n=67). EPTB was detected in 37 (30.1%) patients with lymph node TB being the most common manifestation [17 (46.0%)]. All patients received four-drug anti-TB therapies for 6–12 months. Most patients 111 (90.3%) were cured, and 2 (1.6%) patients died during the course of the disease, while 10 (8.1%) patients were lost during follow-up. Conclusion: The prevalence of TB in Shabwah Governorate was 14.5/100,000 population. Male patients and younger age groups were more affected, while the lymph nodes were the main extrapulmonary sites involved and the cure rate was 90.2%. The results of the study indicate the need to revise the notification form for active TB cases and to expand NTP activities to focus on targeted screening for active TB cases in high-risk groups to close the gap in unidentified TB cases.

Picky eating behavior and incidence of malnutrition among children aged 2-5 years in blora, indonesia: a case-control study

Background: Malnutrition is a deficiency of nutrients due to inadequate energy intake. Picky eating behavior in children could be a cause of malnutrition, but previous studies’ results were still inconsistent. This study aimed to determine the relationship between picky eating behavior and malnutrition among children aged 2-5 years. Methods: This case-control study involved 70 children aged 2-5 years in Kutukan Village, Randublatung District, Blora Regency. Malnutrition was defined as a weight-for-age Z score <-2.0 SD based on the WHO classification. Child eating behavior was evaluated using the Child’s Eating Behavior Questionnaire (CEBQ), identifying picky eaters if the food avoidance score surpassed the food approach score. Data analysis employed the Chi-Square test. Results: Boys experienced more malnutrition, with 20 (57.1%) affected, and the most affected age group was 24-35 months, with 19 (54.3%). Questionnaire processing revealed that the number of picky-eater children in the malnutrition group was 33 (94.3%), while in the non-malnutrition group, there were 31 (88.6%). Bivariate analysis showed no relationship between picky eating behavior and malnutrition in children aged 2-5 years (p=0.673; CI 95%=0.364-12.459). Conclusion: This study found no significant relationship between picky eating and malnutrition in children aged 2-5 years.

Evaluation of four trichoderma spp. for the biological control of black bundle disease (cephalosporium acremonium) in maize

Four Trichoderma species with known biocontrol activity (T. harzianum, T. hamantum, T. viride and T. virens) were tested for their efficacy against Cephalosporium acremonium, a causal organism of Black bundle disease in maize. Interactions between the fungi were assessed in vitro to study mutual antagonisms. Among the four bio-agents, T. hamantum proved to be promising which showed maximum inhibition (51.3%) followed by T. virens (45.2%), T. harzianum (44.6%) and T. viride (20.3%). T. hamantum was also found to be hyperparasite on C. acremonium whereas, T. harzianum and T. viride showed mycelial deformation. The volatile toxicants released by all the Trichoderma spp. were inferior in inhibiting the growth of C. acremonium when compared to the control as evident by inverted plate technique. The results of in vivo experiments confirmed the results from the in vitro study and showed that all the four bio-agents significantly reduced the disease incidence of Black bundle disease.

The management of lateral epicondylitis: a narrative review

Lateral epicondylitis, commonly known as Tennis Elbow, affects approximately 1-3% of the population. Despite the absence of histological evidence of inflammation in the affected tissue, the term “epicondylitis” implies inflammation. The Extensor Carpi Radialis Brevis (ECRB) muscle is primarily affected, and the condition is attributed to excessive use of this muscle. Non surgical treatment options, such as rest, physiotherapy, cortisone injection, platelet-based therapies, and restricted movements, are recommended. Surgical intervention is suggested for cases involving physical impairment or chronic pain. This review aims to provide healthcare professionals with an understanding of the condition, including its causes, symptoms, diagnosis, and treatment planning options.

The effect of phaseolus vulgaris l. fixed oil on the behavioural activity of swiss albino mice

Background: Phaseolus vulgaris, commonly known as kidney bean, has been studied previously for pharmacological properties such as antidiabetic, antioxidant, analgesic, anti-inflammatory, antifungal, and antibacterial properties. Various extracts of the seeds have been researched except fixed oils. Objective: Therefore, the present study aims to investigate the behavioral activity of fixed oil extracted from Phaseolus vulgaris seeds. Methodology: Hole board, light and dark, stationary rod and open field tests were used for behavioral evaluation. Four groups were made with seven mice in each : (1) Control = Normal saline 2ml/kg (2) Phaseolus vulgaris fixed oil = PVFO 2ml/kg (3) PVFO 4ml/kg (4) Diazepam (1mg/kg) as standard. All treatments were given orally 30 minutes before the performance of tests. In the hole board test, PVFO 4ml/kg decreased the number of head poking (p≤0.01). Results: In light and dark tests, PVFO in both doses reduced the time spent in the light compartment (p≤0.01). In the open field test, the number of peripheral lines crossed was decreased (p≤0.05), whereas in the stationary rod test, no effect was observed by any dose of PVFO. Conclusion: Results indicate that Phaseolus vulgaris fixed oil does not affect memory or learning in mice and may possess a dose-dependent sedative hypnotic effect.

Critical race theory pdf

Critical race theory (CRT) is an intellectual movement that seeks to understand how white supremacy as a legal, cultural, and political condition is reproduced and maintained, primarily in the US context. While CRT is part of a much longer research tradition investigating race and racism, which includes such key fgures as W. E. B. Du Bois, Frantz Fanon, Angela Davis, Audre Lorde, Gloria Anzaldúa, Cherríe Moraga, and many more, CRT distinguishes itself as an approach that originated within legal studies (in part building from and responding to critical legal studies); aims to be a vehicle for social and political change; has been adopted interdisciplinarily across many fields, including perhaps most notably education; and, in certain contexts, has come to be the umbrella term for studies of race and racism generally. CRT originated as an extension and critique of critical legal studies (CLS). It was also an outgrowth of Marxist critical theory that challenged the rationality, impartiality, and purpose of the legal system. According to the tenets of both CRT and CLS, the legal system is a political and ideological institution that, in part, rationalizes and justifies the existence of the state. Te legal system also requires mastery of an arcane and intentionally inaccessible vocabulary and a set of knowledge and power processes that limit ordinary people’s access to it. Te arbiters of law pretend to rely on reason but actually rely on subjective, politically motivated, culturally biased, and quasi-religious rationale for making and enforcing their decisions. CRT maintains the critique of legalistic thinking found in critical legal studies, but then adds a framework for understanding white supremacy as an immutable fact of a neocolonial state, as well as a praxis for changing it. What separates CRT from other forms of racial critique is that, “Unlike most of the earlier genres of race cholarship, critical race scholarship does not treat race as an independent variable; rather, it regards race as a site of struggle” (Orbe & Allen, 2008, p. 209).

Employment, employability, and competencies of the bachelor of secondary education graduates

Tracing graduates has become an imperative for higher education institutions much more during the pandemic. This tracer determined the employment and employability status of the 2019 BSE graduates and identified the competencies they adequately acquired and deemed vital for work. It used descriptive design, and data were collected from the 103 graduates through a Google form with open and closed-ended questions administered between November and December 2020. Results revealed that most of the graduates had been employed in teaching and teaching-related jobs but mostly in contractual arrangements within the first and second six months after graduation. Many had their first jobs with meager salaries from the private sector. Communication, pedagogy, information communication technology, time management, and flexibility were the top competencies they adequately acquired and were beneficial in work. The study concluded that these graduates had acquired 21st-century skills in their respective degree programs. These results have corresponding implications for future research in confirming the most employable skills in secondary teaching. As recommended, classroom instruction might emphasize the development of these skills. Eventually, these become the competitive advantage and employability capitals of future graduates. Administering the licensure examination and the release of its results can be done within the first three months after graduation to lessen the cost of waiting.

Prevalence of acute infectious hepatitis in eastern libyan pediatrics

Viral hepatitis is one of the main public health concerns around the world. Even though infection management techniques have been implemented over the last few decades, eradication or significant reduction has remained a mystery. The purpose of this study is to look into the prevalence of acute infectious hepatitis in the East of Libya and how the type of virus, age, gender, clinical manifestations, and outcome are related. This is a hospital-based retrospective study. The data on the frequency and distribution of viral hepatitis based on age, gender, seasonal, clinical, and ultrasound findings, and the outcomes during a period of two years from January 2020 to December 2021 were collected and analyzed. Of the 0.39% (72 cases) of total hospital admissions (18340) under the age of 15 years old for acute infectious hepatitis patients, the most common age group was 5-12 years (79.6%). Winter accounted for 41.6% of all the cases. Females made up 65.3% of the cases. Jaundice was the most prevalent presentation (87.5%). Hepatomegaly was seen in 83.3% of the patients. Most of the cases have mild hyperbilirubinemia (5-9 mg/dL, 75.0%). Approximately 1/5th of the patients' serum glutamic-oxaloacetic transaminase (SGPT), and nearly 1/3rd of the patients' SGPT levels were in the range of 1000-2000. One patient's hepatitis C was positive, one patient's hepatitis B was positive, and 97.2% were positive for hepatitis A. 88.8% of the individuals recovered without complications, whereas 11.1% showed symptoms of hepatic failure but recovered. The present study indicates that acute hepatitis A is more prevalent, especially in the winter. Those who are females and 5-12 years of age were more affected by acute viral hepatitis in Libya.

A framework for using satellite images to estimate pv systems' generating capacities

Numerous initiatives to rely on new renewable energy sources, such solar electricity, have been sparked by the increased interest in global warming. With an increase in home photovoltaic (PV) panels that are available to the public, more precise calculations of energy generation are now possible. Segmenting satellite images offers a straightforward and inexpensive way to categorize solar panels..This work suggests a method for classifying and segmenting solar panels that combines the watershed algorithm with deep learning approaches. First, a Convolutional Neural Network (CNN) architecture with the ResNet, EfficientNet, and Inception architectures is used for classification. Through the fine-tuning of pre-trained networks on a heterogeneous dataset of solar panels, transfer learning improves performance. The categorization model recognizes solar panels in a variety of settings with accuracy, making maintenance and monitoring easier. After classification, the watershed method uses intensity gradients to precisely delineate solar panels from the background. Tasks like defect detection and layout optimization are made easier when deep learning-based classification and watershed segmentation are combined. The outcomes of the experiments show how well the suggested method performs in terms of segmenting and classifying solar panels under various circumstances. A flexible automated solar panel management solution is provided by the combination of deep learning and the watershed algorithm, which promotes increased sustainability and efficiency in solar energy systems.

Synthesis and broad spectrum antibacterial activities of 2-pyrazolines synthesized from chalcones

2-Pyrazolines are well known, and important nitrogen-containing five-membered heterocyclic compounds which belong to the family of azoles and have been found to possess considerable activities, like anticancer, antibacterial, antifungal, immunosuppressant and antiamoebic activity. In the present work, ten novel pyrazolines were prepared from chalcones, characterized and evaluated for their antibacterial activity against Staphylococcus aureus and Escherichia coli using Ciprofloxacin as standard and using DMSO as a solvent. Their activity was evaluated by measuring the zone of inhibition in mm. All the compounds exhibited antibacterial activity against Staphylococcus aureus and Escherichia coli. Among ten derivatives of compounds synthesized, the derivative with 2-chloro and 4-chloro substituted phenyl rings attached to pyrazolines exhibited the highest activity against both types of organisms. The derivatives with an unsubstituted phenyl group attached to pyrazolines exhibited comparatively less activity. Thus it can be concluded that pyrazolines containing substituted phenyl groups are effective broad spectrum antibacterial agents, and they can be developed as effective antibacterial agents.

Experimental investigation and cfd analysis of different diameter evacuated tube solar water heater

The share of renewable energy share in India's energy mix of India has been increasing recently owing to the promotion and implementation of various government policies that promote the use of renewable sources of energy, depleting fossil fuel levels, increasing fuel prices, and stringent laws for emission reduction worldwide. The increase in the use of solar-evacuated-tube-collector-based domestic water heating is the result of this transition from conventional to nonconventional sources of energy. The recent urban agglomeration is challenging to install these solar water heaters in every household because the roof space is limited. Space reduction can be achieved by reducing the collector area by varying the diameter of the evacuated tubes. This study used a single tube and tank arrangement model with a fixed inclination to achieve a thermosyphon effect in a solar water heating system with three different diameter configurations of 48 mm, 54 mm, and 72 mm, with a tube measuring 1800 mm in length. Thermal assessment of the thermosyphon-based evacuated tube-solar water heater using the ANSYS CFD simulation software involves measuring the temperature at three different positions in the tank to study the thermosyphon initialization. This study signifies that the 72-mm-diameter evacuated tube is more capable of initializing the thermosyphon effect in the system. Nevertheless, the final temperature of the system is better achieved in the 48-mm-diameter evacuated tube

Cellular manufacturing layout design using heuristic clustering algorithm and lpp model

This mathematical model forms machine cells, optimises the costs of unassigned machines and components, and designs the shop floor cell layout to have minimal movement of materials. The complete similarity measure algorithm forms machine cells and part families in a refined form. Later, exceptional elements are eliminated in the optimisation model by using machine duplication and sub-contracting of parts. Then the shop floor layout is designed to have optimised material movements between and within cells. An evaluation of the cell formation algorithm’ performance is done on the benchmark problems of various batch sizes to reveal the process’s capability compared with other similar methods. The data of machining times are acquired and tabulated in a part incidence matrix, which is used as input for the algorithm. The results from the linear programming optimisation model are that costs are saved, machines are duplicated, parts are sub-contracted, and there are inter- and intra-cellular movements. Finally, the output of the inbound facility design is the floor layout, which has machine cell clusters within the optimised floor area.
