Pollution of the environment, in particular water sources, with heavy metals is a serious environmental problem. In this regard, it is relevant to develop new sensor systems that allow rapid tests and are not inferior in analytical parameters to classical methods for detecting heavy metals. Promising materials for creating such sensor systems are composite coatings based on polymer compounds with inorganic nanoparticles. The article presents the results of using poly(methyl methacrylate) (PMMA) coatings and PMMA nanocomposites with silicon dioxide nanoparticles (SiO2 NPs) to develop capacitive sensors for analyzing the content of Ni2+ ions in water. The structural and morphological characteristics of a conductive nickel layer and nanostructured films based on poly(methyl methacrylate) were studied using atomic force microscopy. Based on the experimental data on the dependence of the capacitance characteristics of sensors on the concentration of Ni2+ in solutions, the operating characteristics of sensors were established: response time is 5 min; working range of concentrations of Ni2+ ions: 1 ‧ 10–3 – 50 mM; lower detection limit ≈ 0.06 mg/l (maximum nickel concentration limit in water is 0.1 mg/l). It has been shown that the formation of a coating of the composition PMMA + NPs-SiO2 (1 : 41.7 mol) on a conductive nickel layer using the spin-coating method leads to increasing the sensitivity of a sensor and its service life (up to seven cycles).

The continuous explosion of discoveries in field of science and technology in this 21st century calls for shift from conventional teaching methods to a more innovative teaching strategies in Nigerian secondary schools. Instructional strategies adopted by teachers have been linked by researchers to studentsâ€™ conceptions, misconceptions, difficulties of some concepts as well as poor performances in science subject like Biology at the senior school certificate examinations in Nigeria. Genetics is one of the concepts in Biology that was reported by researchers to be difficult to teach by teachers and difficult to learn by students in secondary schools in Nigeria. This study examined the effect of using 5E learning-cycle and concept-mapping in teaching genetics to senior school students offering biology. The study is a quasi-experimental type. Sample comprised of senior school two students in public secondary schools in Ilorin city. The study is a quasi-experimental type involving pretest, posttest, non- randomized and non-equivalent control groups. All Senior School two (SS II) Biology students were the targeted population. The target population will not be preparing for WASSCE. A purposive sampling technique was used to select co-educational government secondary schools in three senatorial districts. A Performance Test on Genetics (PTG) was used for data collection. Data collected were analyzed using mean and ANCOVA statistical tool. The study revealed that both learning-cycle and concept- mapping had a positive effect on the performance of the experimental groups. It means there is a significant difference between the experimental and control groups and also, no significant difference between the performance of male and female students. It was therefore recommended among others that teachers should employ these strategies to teach biology particularly genetics

Published: July 2024

The electricity distribution substation is one of the components of the electricity distribution system. Electrical distribution substations, especially portal pole-type electrical distribution substations, can emit ELF fields. However, people need to be aware of the health risks of ELF fields and continue to carry out various activities near electricity distribution substations. This research aims to create a distribution pattern for ELF Field and determine its safety level based on WHO thresholds. The research was conducted in the Jember Regency, particularly in Sumbersari District. This research uses a portal pole-type electricity distribution substations. The substation criteria studied were a portal pole distribution substation on a 20 kV transmission line with a transformer capacity of 160 kVA. The measurement points are 0 m below the transformer, 0.7 m, 1.4 m, 2.1 m, 2.8 m, 3.5 m, 4.1 m, and 4.9 m from the distribution substation building at a height of 1.5 m from the ground for three days at 21.00 WIB and 30 measurements were taken. The distances of these points to the transformer are 4.256 m, 4.313 m, 4.480 m, 4.745 m, 5.094 m, 5.510 m, 5.979 m and 6.490 m respectively. The type of research used is quantitative research with survey data collection techniques. The research design used was cross sectional study. Cross sectional study is a type of observational research design that collects data at one specific point in time from a sample which represents the population studied. ELF field measurements show a spherical distribution pattern with an average magnetic field intensity between 0.0358 µT and 2.91 µT and an average electric field intensity between 2.35 V/m and 16.42 V/m. The magnitude of the magnetic field and electric field measured gets smaller as the distance from the measurement point increases. According to WHO, these results are below the threshold for the general group. This research concludes that the portal pole-type distribution substation in the medium voltage network produces a safe ELF field with a spherical distribution pattern that is inversely proportional to the distance.

O câncer pancreático afeta no Brasil 2% de todos os tipos de neoplasia diagnosticados. Maioria absoluta origina-se dos ductos que transportam o suco pancreático, que são os adenocarcinomas, cerca de 90%. Os principais fatores de risco são: idade entre 60 e 80 anos, gênero masculino, raça negra, tabagismo e exposição ocupacional a carcinógenos. Pelo fato de ser de difícil detecção, o câncer de pâncreas apresenta alta taxa de mortalidade, por conta do diagnóstico tardio e de seu comportamento agressivo. Relato de Caso: Paciente do gênero masculino, 59 anos, com história de icterícia associada a inapetência, prurido e perda ponderal de 27kg em um mês. Tomografia Computadorizada de abdome evidenciou dilatação de vias biliares e tumoração de cabeça de pâncreas ressecáveis. Realizada a abordagem inicial através de CPRE com colocação de prótese transpapilar e imunomodulação perioperatória, seguido de Duodenopancreatectomia. Devido deiscência de anastomose gastroentero, foi realizada reabordagem do sítio operatório e confecção de Jejunostomia. Evoluiu sem fístula pancreática e outras complicações. Conclusão: a Pancreatectomia é o único tratamento com potencial de cura para tumores pancreáticos, porém apenas 20% dos pacientes são candidatos a cirurgia. A detecção precoce e rápida mobilização para serviço de referência possibilitou a adequada avaliação multidisciplinar e preparo do paciente para procedimento cirúrgico. Complicações operatórias desse complexo procedimento são comuns e devem ser identificadas precocemente. O paciente segue com boa evolução e continua em acompanhamento médico com equipe.

A hanseníase é uma doença infectocontagiosa causada a partir da bactéria Mycobacterium leprae, e é considerada crônica. Devido ao contexto histórico dessa enfermidade, ainda existe muito preconceito e estigma a respeito dos hansenianos. O objetivo do trabalho buscou descrever a percepção dos portadores de hanseníase sobre o estigma da doença. Trata-se de uma revisão integrativa de literatura realizada na base de dados PubMed, Biblioteca virtual de saúde (BVS) e SCIELO; utilizando as palavras chaves “hanseníase”, “estigma”. Foram localizados 220 artigos e após os critérios de elegibilidade foram selecionados 10 artigos para a revisão. Após a leitura e análise desses artigos notou-se que o estigma e preconceito ainda estão muito prevalentes na sociedade atual e acaba impactando os portadores no âmbito da saúde mental quanto nas relações sociais. É notório que o estigma e o preconceito atrasam o diagnóstico, e consequentemente os tratamentos desses pacientes, logo, além desses terem que viver com o receio da própria doença, também, tem que se preocupar com os impactos negativos nas suas relações pessoas, saúde mental e exclusão da sociedade.

THE EFFECT OF HIGH FLUORIDE INTAKE ON SODIUM, AND POTASSIUM AND CALCIUM LEVELS IN SHEEP BLOOD SERUM
Authors: S.M. Hussain , N.M‎. Al-Shathir, , Kh.K‎ Kudhaier, , A.W.R. ‎ Mehdi,
Published: July 2024

This experiment was carried out to investigate levels of sodium, potassium and calcium in ovine blood serum for 12 weeks during which fluoride (100 ppm) was added to the ration. The rams remained physically in good condition and there were no lesions in the teeth, gums and joints. With the exception of an increase in sodium at the end of the first week, sodium and potassium levels were not influenced. This finding could point out to the possibility of failure of the added fluoride to induce significant changes in kidney and aldosterone functions regarding regulation of these two ions in blood. There was a general tendency of the total calcium level to decrease which reached statistical significance in samples of three weeks. Such decrease could be due to a decline in calcium intestinal absorption and an increase in bone deposition and excretion with urine.
THE EFFECT OF SUB-CLINICAL INFECTION WITH HAEMONCHUS CONTORTUS ON PRODUCTION PERFORMANCE IN THE ‎PREGNANT EWES
Authors: T. Jerjees M. , A. Ali D. , M. Al-Saquar ‎ I.
Published: July 2024

Fourteen Bulgarian pregnant ewes (three months of gestation), were used and divided in two groups, one group was inoculated with 500 infective larvae /kg. body weight, the other group remained non-infected control. Productive parameters, blood changes were recorded and faecal egg counts were examined weekly. Marked reduction in food intake was recorded in infected ewes, especially during prelambing period. No obvious differences were noted between both groups after lambing. Slight differences in body weight gain were recorded between both groups until labour, while after lambing, the weight losses of infected ewes were highly significant 1%. No effect of infection has been seen on fleece weight, while significant depression in the haemoglobin and packed cell volum of infected group during the pre-parturient period, and the high reduction occured at week (7). Generally the results indicated that there were variations in resistance of ewes or its susceptibility to parasitic infection.

One- day old broiler chicks were divided into four equal groups and given rations containing four different levels of dl-α -tocopheryl acetate (10, 40, 70 and 100 mg/kg of feed). Each ration was given’ to one group. Body weight was increased significantly in groups consumed rations containing 70 and 100 mg of dl-a tocopheryl acetate per kg of feed. Feed consumption has not. been increased in these two groups which give economic weight to the results. Tt is concluded that dl-α-tocopheryl acetate may be considered as growth promotor.

Published: July 2024

Spores of Bacillus subtilis HU1 suspended in whole milk and /or distilled water subjected to high and ultrahigh temperatures ranging from 85 to 14°C. Resulting survivor and thermal death time (TDT) curves were shown to be non-linear for all temperatures investigated; convex survivor curves at most heating temperatures were observed. TDT curves observed in all studies were concave and biphasic. The z-value using milk as the menstruum were 57°C for heating temperatures of 121-140°C, and 20°C, for heating temperatures of 110-121°C. Distilled water as the menstruum yielded z-values of 58°C and 16°C for heating temperatures of 120-140°C and 110-121°C respectively.
