Heavy metal pollution in the western part of Peshawar metropolis, north Pakistan
Authors: Hamidullah Syed , Khan M. Sultan , Shah M. Tahir 
Published: April 2021

Peshawar is the capital of North-West-Frontier-Province (NWFP) and the largest trade centre in the northwestern part of Pakistan. Due to high rate of urbanisation and the sudden influxes of Afghan refugees in the past two decades, the city has become one of the most polluted ones in the South Central Asia. The increased load of transportation with no or limited expansion of roads, unplanned and uncontrolled industrialisation and poor sanitation have caused the atmosphere unprecedently overburdened with smokes and dusts of all kinds. This paper is a part of a detail study carried out to determine heavy metal concentrations in air dust, soil and sewerage of the Peshawar metropolis.
In the western part of Peshawar metropolis at 16 chowks (road crossings), air dust samples were collected at nose height and at ground positions in open buckets filled with distilled water for 48 hours. From the same locations, clay/road-mud samples were collected from solidified clay on ground surface. Similarly, soil samples were collected from non-metalled parts at 2 feet depths in subsurface from 10 locations. Correspondingly, sewerage samples were collected from sewerage water and sewerage mud. Vehicular traffic counting was carried out at each chowk for 12 peak hours. At nose height the heavy metal contents showed ppm ranges of: Cr= 0.06-3.2, Co= 0.3-2.4, Ni= 0.17-5.97, Cu= 0.88-8.8, Zn = 0.81-17, Fe = 3-57 and Pb 2-25. The heavy metals concentrations at ground positions were noticed to be higher than at the nose level. The soil samples do not show significant enrichment in heavy metals and are therefore classified as the normal soils. In sewerage water samples the heavy metals concentrations showed ppm ranges of Cr= 0.1-3.81, Co= 0-2, Ni = 0.1 -3, Cu = 0.13-3, Zn = 0.1 - 4.3, Fe = 13 -99 and Pb = 1.81-10. Sewerage mud showed higher concentrations of these metals as compared to sewerage water. A systematic positive variations between the atomic masses of the metals and their concentrations was noticed in air, clay, sewerage water and sewerage mud, indicating that the higher the atomic mass, the higher was the rate of fall/deposition of that particular metal, if available. It was also noticed that compared with water, air is a finer sorting agent for heavy metals.
At each chowk, both individual metal and the total dust fall showed positive correlation with the total number of vehicles, indicating that the moving vehicular traffic is the major cause of keeping metals­ loaded dust in the air. However, these vehicles may not be considered as the major source of emanating these metals from their exhausts. The study showed that the major sources of heavy metals in the western part of Peshawar metropolis are small metal shops, workshops, construction projects, rusted bridges, fences and vehicles on the roads as well as the damaged sewerage system.

Published: April 2021

The palaeohydrological studies of the Middle Member of the Amlekhganj Formation, Nepal Sub Himalaya, are based on the grain size and flow depth for values of the palaeoslope gradient, palaeovelocity, and palaeodischarge. The grain size distribution was measured by using the laser diffraction particle size analyser (SALD 3000S; Shimazu), and the flow depth was estimated from the autogenic fining upward succession. The measured values of the palaeoslope gradient, palaeovelocity, and palaeodischarge were 1.21-1.88x10-6 m/m, 0.67-0.78 m/s, and 103-105 m3/s, respectively. The palaeoslope is comparable to the slopes of such modern Himalayan frontal fans as the Kosi Fan.

Published: April 2021

Microfacies analysis and ammonite biostratigraphy of the Mianwali Formation of the Kala China Range were worked out on the basis of stratigraphic sections from Chak Jabbi and Bagh. Four microfacies were identified from the Chak Jabbi section while amrnonite biostratigraphy was studied from both the sections. Filamentous bivalves in micrite deposited along a shelf margin below normal wave base represent the first microfacies. The second microfacies contains bioclastic wackestone deposited in an open marine environment of normal salinity. The third microfacies consists of lime mudstone formed in a stressed environment of lagoonal conditions, whereas the fourth microfacies of dolomitised carbonate mudstone was formed by the diagenetic dolomitisation of the third microfacies.
The new collection of ammonites includes Arctoceras tuberculatum, Anakashmirites aff. evolutus, Meekoceras gracilitatis, Stephanites sp., Pseudoceltites sp., Subvishnuites aff. welteri, Arnautoceltites sp., Owemtes sp. indet, Subvishnuites aff. enveris, Pseudosageceras sp. indet, Paranannites sp., Subcolumbites sp., Anasibrites sp., and Pseudaspidites sp, confirming the already known Sctythian age of the Mianwali Formation.

В статье приведены сведения об апробации современных методов и уточнений видовой принадлежности почвообитающих личинок щелкунов (проволочников) на основе молекулярно-генетического анализа (ДНК-баркодирования). Впервые получены данные по полной идентичности определенных ДНК-последовательностей ряда видов щелкунов (Coleoptera: Elateridae), обитающих на территории Костанайской области(Казахстан), — опасных вредителей сельскохозяйственных культур. В то же время в мировом генетическом банке (GenBank) не обнаружены идентичные ДНК-последовательности расшифрованных нуклеотидных последовательностей ДНК для ряда изученных экземпляров. Основой для настоящего исследования послужили материалы, собранные в 2018 г. в подзоне обыкновенных черноземов на супесчаных почвах (Мендыкаринский район). Отбор личинок проводился методом стандартных почвенно-зоологических проб. Фиксация и хранение отобранных личинок щелкунов осуществлялись по методике подготовки образцов для молекулярно-генетического анализа с фиксацией в 96 %-ном спирте. После традиционного определения таксономического положения собранных экземпляров идентификация видов происходила методами генетического анализа по нуклеотидной последовательности гена субъединицы 1 цитохром С оксидазы(COI). Работы были проведены в ДНК-лаборатории Музея естественной истории Университета г. Осло (Норвегия). Сборка и расшифровка нуклеотидных последовательностей ДНК исследуемых образцов велись с помощью программ «CodonCodeAligner» и «MEGA-X». В результате исследований удалось выявить полную идентичность ДНК-последовательностей нескольких массовых видов щелкунов, тогда как ряд расшифрованных ДНК-последовательностей модельных экземпляров отсутствовал в генетическом банке, что требует пополнения его новыми данными.

Welding is a very important part of the development and growth of the industry because it has a role in engineering, reparation, and construction. ShieldedÂ Â MetalÂ Â Arc Welding (SMAW) or the conventional arc weldingÂ Â process is particularly dominant in structural joints, pressure vessels and in maintenance and repair work. In welding, different metals are joined economically and at a much faster rate as compared with other fabrication processes like riveting and casting. The purpose of this research is to find out the cooling media cooler against SMAW smelter tensile strength by using the E6013 electrode. This study uses low carbon steel material that has levels Fe = 98,3%; C = 0,30%, Si = 0,23%. The material is given 75A welding current with cooling variation on the connection result using oil, water, and room temperature. The highest tensile stress value obtained in the oil cooling treatment was 844,76 N/mm2, the highest strain value was obtained on the raw materials of 16%, the highest elasticity value was obtained in the oil cooling treatment of 703.96 N/mm2. According to the research results can be concluded that the variations of cooling media greatly affect the strength of the welding connection.

Relevance and methods. The article considers the experience of studying the effect of crossing Kalmyk sheep and dorper sheep-breeders in order to increase meat productivity. Crossbred rams of the experimental group had better indicators than rams in the control group in terms of live weight, depending on the conditions of pasture maintenance. Dagestan has a fifth of the Russian sheep and goat population and a quarter of wool production. In this area sheep breeding has a unique specificity, twice a year cattle are driven from summer to winter pastures and back. The distance between the pasture areas is more than 570 km. Of the total number of sheep, 71.5% falls on the Dagestan mountain breed.Results. To further increase the level of profitability of fine-wool sheep breeding it is of great importance to develop research on the economic and useful characteristics of young Dagestani fine-wool sheep and their crossbreeds with Russian meat merino sheep, depending on the driving and pasture system of keeping.

The article presents the results of determination of acute and subacute toxicity of the drug “Tilovet 20 %”, which was made on the basis of tylosin tartrate. In result of the conducted researches, it was found out, that LD50 of the drug “Tilovet 20 %” by intramuscular injection to white mice (calculated by the method of G. Kerber) is 10000 and mg/kg, and for white rats – 9583.33 mg/kg. Long-term use of the drug in a therapeutic dose caused a tendency to the decrease of hemoglobin concentration, amount of erythrocytes, platelets, hematocrit value, mean corpuscular hemoglobin (MCH), mean corpuscular volume (MCV), content of the total protein, creatinine level, ALP activity on the background of a slight an increase of amount of leukocytes, urea level, AST and ALT activity compared to the values of the control group. The use of the drug in a dose that is 10 times higher than the therapeutic, caused a probable decrease of hemoglobin concentration by – 6.6 % (P < 0.05), platelet count by – 32.5 % (P < 0.05), mean corpuscular hemoglobin (MCH) by – 4.2 % (P < 0.05), mean corpuscular hemoglobin concentration (MCHC) by – 1.5 % (P < 0.1), hematocrit value by – 4.95 %, and total protein content by – 10.7 % (P < 0.05), on the background of a slight an increase of amount of leukocytes by 5.3 %, ALP activity by – 17.5 %, compared to the values oft he control group. Therefore, all of the above may indicate to the suppression of hematopoietic processes and a decrease in the protein-synthesizing function of the liver.

El uso público de las áreas naturales protegidas incluye los usos turístico, educativo, interpretativo, recreativo y de investigación, realizados por visitantes que participan en actividades que no extraen ni introducen elementos ajenos al área. El objetivo de esta investigación fue establecer una visión colectiva sobre las condiciones sociales y biofísicas deseadas para el Parque Nacional Islas Marietas, México. Esto se construyó mediante talleres participativos con actores clave, para promover el diálogo entre cerca de 200 participantes a través de la herramienta World-Café. Se discutió la problemática de la visitación y actividades recreativas. Establecieron las inquietudes y oportunidades, luego emitieron sus conclusiones con respecto a la problemática que jerarquizaron de acuerdo a su importancia y se consensaron. La problemática identificada y jerarquizada con respecto a la visitación del parque fue: concentración de visitantes en un mismo lugar que rebasa la capacidad de carga y disminuye la calidad de la experiencia; que, aunque los prestadores de servicios turísticos han mejorado su actitud, existen malas prácticas y violaciones a las reglas; que la promoción del parque es inadecuada; que la vigilancia es insuficiente; que las zonas frecuentemente visitadas han disminuido su atractivo para el buceo autónomo y se han deteriorado las comunidades coralinas en la zona. Con esta información se estableció una línea base socialmente acordada para el manejo del área, proceso que constituye la base para el uso público que todavía está en proceso y donde participan diversos actores.

Authors: Oducado Ryan Michael Flores 
Published: April 2021

Introduction: Research is one of the competencies expected of a beginning professional nurse. While research attitude has been widely explored among nursing students internationally, there is limited published research among nursing students in the Philippines.
Objective: This study was conducted to find out the factors associated with attitude towards research among nursing students.
Method: The design of this study cross-sectional with 79 undergraduate third-year nursing students in one higher education institution in the Philippines as participants. The Attitude Toward Research scale was the primary data collection tool. Differences in research attitude were tested using t-test and one-way ANOVA.
Results: The results indicated that nursing students generally had positive attitude towards research. Graduates of public junior and senior high schools, those who had experience doing research in junior high school, and those who had presented in a research conference outside their school had significantly better research attitude. In addition, differences in research attitude were also noted based self-rated level of research knowledge, competence, and readiness.
Conclusion: Type of high school, prior experience, knowledge, competence, and readiness in conducting research were significant factors influencing nursing students’ research attitude. Nursing schools should continue to raise and cultivate the positive attitude of students towards scientific investigation.

Objetivo: O objetivo do trabalho foi evidenciar as características gerais da Salmonella spp. quanto à fisiopatologia, dando enfoque nas formas de controle e correlacionar a higiene com a segurança alimentar. Metodologia: foi realizada uma busca nas bases de dados bibliográficas: Science Direct, Google acadêmico, Pubmed e Scielo, para selecionar artigos publicados entre os anos de 2011-2020. Os termos utilizados foram: Infecções alimentares, Salmonella spp, segurança alimentar, carne de frango, associados entre si nos idiomas português e inglês. Resultados: O processo infeccioso por Salmonella spp. é complexo, a bactéria é capaz de produzir mais de 400 proteínas que provocam reações inflamatórias, mesmo que não estejam hospedadas no interior da célula intestina e dependendo do seu sorotipo pode causar várias doenças, como gastroenterites e febre tifoide. Conclusão: Diante do exposto, é possível concluir que a Salmonella spp. está entre os principais agentes envolvidos nas toxinfecções alimentares, é comumente isolada em alimentos de origem avícola (bem como alimentos elaborados à base de ovos) e suinícola, essa transmissão também é ocasionada pela ausência de higiene por parte dos manipuladores, bem como o modo de armazenamento inapropriado dos produtos e consumo de alimentos in natura ou mal-cozidos.

In the present study, we conducted a survey on ethnobotanical information of chemical-pharmacological interest, which was acquired via on-site interviews using semi-structured questionnaires with informants in the community in Mucuri Basin in Minas Gerais, Brazil. 184 interviews were conducted with residents with 102 botanical species in approximately 87 genera and 41 families cited. In addition, respiratory system diseases were the most cited, accounting for 26.35% of the cases cited. Lippia alba (lemon balm) was the most cited species with a corrected popular use concordance of about 86.11%. The results suggested that vegetables are important therapeutic resources for the population. Such ethnobotanical studies are fundamental for the understanding and conservation of local culture with regard to the exploitation of medicinal plants. The findings of the present study contribute to the documentation of medicinal species in a Brazilian state characterized by mining, which implies the suppression of vegetation growth or the impairment of regeneration, which could lead to the disappearance of critical and invaluable plant species. The preservation of ethnobotanical knowledge is vital in areas with high human activity and areas undergoing deforestation.

The objective of this study is to evaluate the effect of a Mindfulness-based program on mindfulness levels and in the risk of illness associated with stress at work in primary health care (PHC) professionals in Ribeirão Preto, Brazil. This is a quasi-experimental study, with 26 PHC professionals, using quantitative methods and an analytical before and after approach of an 8-week Mindfulness Program. The intervention was evaluated applying the instruments: Five Facet Mindfulness Questionnaire and Job Stress Scale. There were significant differences in six Mindfulness facets after the intervention: Observe (p = 0.002); Describe (p = 0.01); Act with awareness - autopilot (p = 0.01) and distraction (p = 0.05); Non-reactivity to inner experience (p = 0.0005); Non-judgement of inner experience (p = 0.01); and in total Mindfulness scores (p = 0.0000018). Regarding the stress levels at work, the reduction of the organizational mode in high job strain was observed (before: 35%, after: 19%). It is concluded that interventions based on Mindfulness applied to PHC professionals can improve the levels of mindfulness and modify the modes of organization at work, reducing the risk of illness associated with stress in these professionals.
