Opis:
Introduction: Medicinal plants are found throughout the world but most are considered weeds. They are – directly or indirectly – the major source of medicines in pharmaceutical and herbal industries. Formulations used to prepare medicines or the method of use for these plants are mainly based on folk or traditional knowledge. This folk knowledge is not documented in many areas and needs to be explored. Objectives: This study was aimed to enlist the seasonal weed species with traditional medicinal usage in Toba Tek Singh District, Punjab, Pakistan. Methods: Field surveys were arranged in winter and summer 2019–2020 to enlist the important medicinal weeds and traditional knowledge of the local community. Data collected were as follows: local name of weed, medicinal use, method and part used. Results: Numerous wild perennial, biennial and annual plants were identified, 30 of them were ethnomedicinally important in the local community. They were grouped in 16 families. It was found that whole weed is used in many prescriptions (37%). Achyranthes aspera L. (Amaranthaceae) was the most common weed used in treating fevers, respiratory problems and asthma. Cichorium intybus L. (Asteraceae) was used in summer drinks to reduce thirst, improve digestion and liver function. Chenopodium album L. (Amaranthaceae) was used with 0.71 UV and 0.147 RFC values. Medicago polymorpha L. (Fabaceae) was used to treat kidney, intestinal and bladder infections. Its UV was 0.65 and RFC was 0.121. Tribulus terrestris L. (Zygophyllaceae) was used in impotency treatment, and in the removal of kidney stones and urinary tract infections treatment. It has 0.63 UV and 0.21 RFC values. This weed also showed the highest Fidelity Level (FL) (77%), as compared to other weeds. Conclusion: It was concluded that there are many significant medicinal weeds in the Toba Tek Singh District, Punjab, Pakistan that are used in traditional medicines in treating various disorders. These plants also showed herbal or pharmacological importance that can be used to develop medicine at commercial scale.

Opis:
Three-dimensional numerical simulations were carried out with the ABAQUS/explicit finite element code to study the influence of target boundary conditions on its ballistic limit. 1mm thick 1100-H12 aluminum target of 255 mm span diameter was hit by 19 mm diameter and 50.8 mm length blunt nosed projectile. The mass of the projectile was kept as 52.5 gm. The boundary condition effects on the ballistic limit were investigated by varying the target periphery boundary condition as fully clamped and partially clamped target (75%, 50% and 25%) subjected to projectile impact. The energy absorption and ballistic limit of the target was found to be significantly affected by the boundary conditions. Some of the finite element analysis results were compared with experimental and numerical results reported in international literature and a good agreement between the two was found.

Opis:
In the 1990s the financial sector of Pakistan underwent massive reforms. The primary aim of restructuring was to privatize state-owned institutions, abolish entry barriers for new players, and consequently increase the efficiency of the whole system. This study uses an unbalanced panel of 21 commercial banks listed at Pakistan stock exchange throughout 2000 to 2017 from “BankFocus” and “Bloomberg”. This research measures the effect of ownership, competition, and management practices on banks efficiency. The authors found a higher efficiency of private banks in comparison to state-owned counterparts. The empirical analysis suggests that an increase in foreign ownership and institutional ownership impact positively on all measures of efficiency. The relationship between competition and efficiency supports “competition-efficiency hypothesis” and proposes regulatory measures to regulate the market further. Additionally, banks with a higher standard of management practices tend to be more efficient. These findings imply that there is a need to regulate the bigger banks and ease the market entry for foreign and institutional owners, who brings superior managerial standards and hence efficiency.
W latach 90tych XX wieku sektor finansowy w Pakistanie przeszedł ogromne reformy. Głównym celem restrukturyzacji była prywatyzacja państwowych instytucji, zniesienie barier wejścia dla nowych graczy, a w konsekwencji zwiększenie efektywności całego systemu. W przeprowadzonym badaniu wykorzystano niewyważony panel 21 banków komercyjnych notowanych na giełdzie w Pakistanie w latach 2000-2017 z "BankFocus" i "Bloomberg". Badanie to mierzy wpływ własności, konkurencji i praktyk zarządzania na efektywność banków. Autorzy stwierdzili wyższą efektywność banków prywatnych w porównaniu do państwowych odpowiedników. Analiza empiryczna sugeruje, że wzrost własności zagranicznej i własności instytucjonalnej wpływa pozytywnie na wszystkie miary efektywności. Związek między konkurencją a wydajnością wspiera "hipotezę efektywności konkurencji" i proponuje środki regulacyjne w celu dalszego uregulowania rynku. Ponadto banki o wyższym standardzie praktyk zarządzania wydają się być bardziej wydajne. Ustalenia te sugerują, że istnieje potrzeba regulacji większych banków i ułatwienia wejścia na rynek dla zagranicznych i instytucjonalnych właścicieli, którzy wprowadzają lepsze standardy zarządzania, a tym samym efektywność.

Opis:
Carbon dioxide (CO2), Methane (CH4) are two most potent greenhouse gases and are major source of climate change. Human activities particularly fossil fuels burning have caused considerable increase in atmospheric concentrations of greenhouse gases. CO2 contributes 60% of anthropogenic greenhouse effect whereas CH4 contributes 15%. Ice core records also show that the concentrations of Carbon dioxide and methane have increased substantially. The emission of these gases alters the Earth’s energy budget and are drivers of climate change. In the present study, atmospheric concentration of CO2 and CH4 over Pakistan is measured using Atmospheric Infrared Sounder (AIRS). Time series and time averaged maps are prepared to measure the concentrations of CO2 and CH4. The results show considerable increase in concentration of Carbon dioxide and methane. The substantial increase in these concentrations can affect human health, earth radiative balance and can damage crops.

Opis:
Case-study research was carried out with a view to find the attributes of occupational injury among workers in the chemical industry and to enhance safety issues. Injury data were collected and processed in terms of different variables, such as age, gender, skills, type of hazard, etc. Pareto analysis was then applied to find a pattern of occupational injury among the workers. The study revealed that 79.52% of the injured workers were in the 40–59 age group; 57.14% of accidents occurred during the 1st shift; 73.26% of accidents caused injury to hands, feet, chest to thigh, arms and eyes; and 70.93% of injuries were caused by pumps, carrying and lifting, vehicles, pipelines, valves, and grinding. Surprisingly, no one was injured in the group of temporary workers. The paper also provides specific suggestions followed by some action plans.

Opis:
Seed pre-sowing magnetic field treatment was reported to induce biochemical and physiological changes. In the present study, response surface methodology was used for deduction of optimal magnetic field doses. Improved growth and yield responses in the pea cultivar were achieved using a rotatable central composite design and multivariate data analysis. The growth parameters such as root and shoot fresh masses and lengths as well as yield were enhanced at a certain magnetic field level. The chlorophyll contents were also enhanced significantly vs. the control. The low magnetic field strength for longer duration of exposure/ high strength for shorter exposure were found to be optimal points for maximum responses in root fresh mass, chlorophyll ‘a’ contents, and green pod yield/plant, respectively and a similar trend was observed for other measured parameters. The results indicate that the magnetic field pre-sowing seed treatment can be used practically to enhance the growth and yield in pea cultivar and response surface methodology was found an efficient experimental tool for optimization of the treatment level to obtain maximum response of interest.

Opis:
Two separate experiments were conducted during the months of June and September, 2014 to investigate the nutrient (nitrogen and phosphorous) removal from leachate by growing duckweed, Lemna minor in various leachate dilutions under natural climatic conditions of Islamabad, Pakistan. The highest uptake of nitrogen and phosphorous by duckweed was 95% and 90%, respectively, whereas the highest growth rate of duckweed was 6.4 g·m–2·day–1 during both experiments. The highest rates of nitrogen and phosphorous removal from leachate media were 380 and 200 mg·m–2·day–1, respectively, during both experiments. Nutrient uptake by duckweed and its growth rate was rapid at more diluted leachate whereas the nutrient removal rates from leachate media were higher in more concentrated leachate. The duckweed growth and its nutrient uptake ability under natural climatic conditions were directly affected by seasonal climatic variations. Relatively higher temperature and more intense solar radiation were more favorable for the duckweed growth and its nutrient uptake ability. Both parameters can be improved by pre-acclimation of duckweed with leachate which prevents the lag phase of the duckweed growth.

Opis:
The present investigation was conducted to appraise the physiochemical adjustments in contrasting maize cultivars, namely, PakAfgoi (tolerant) and EV-5098 (sensitive) subjected to heat shock. Seven-day-old seedlings were exposed to heat shock for different time intervals (1, 3, 6, 24, 48 and 72 h) and data for various physiochemical attributes determined to appraise time course changes in maize. After 72 h of heat shock, the plants were grown under normal conditions for 5 d and data for different growth attributes and photosynthetic pigments recorded. Exposure to heat shock reduced growth and photosynthetic pigments in maize cultivars. The plants exposed to heat shock for up to 3 h recovered growth and photosynthetic pigments when stress was relieved. A time course rise in the relative membrane permeability, hydrogen peroxide (H2O2) and malondialdehyde contents was recorded particularly in the EV-5098 indicating that heat shock-induced oxidative stress. Activities of different enzymatic antioxidants greatly altered due to heat shock. For instance, an increase in superoxide dismutase activity was recorded in both maize cultivars. The activity of ascorbate peroxidase was greater in Pak-Afgoi. However, the peroxidase and catalase activities were higher in plants of EV-5098. Heat shock caused a significant rise in the proline and decline in the total free amino acids. Overall, the performance of Pak-Afgoi was better in terms of having lesser oxidative damage and greater cellular levels of proline. The results suggested that oxidative stress indicators (relative membrane permeability, H2O2 and malondialdehyde) and proline can be used as markers for heat shock tolerant plants.

Opis:
Plastic is one of the main pollutant sources that are difficult to decompose and then carried into the ocean and fragmented into smaller parts (microplastics) due to UV radiation and water currents. Their small size means that microplastics are often ingested by aquatic organisms, such as fish. This research aimed to determine the presence, abundance, and types of microplastics in the digestive tract of four dominant fishes landed at Lengkong Fish Auction Point, Cilacap, Central Java, i.e. threadfin (Eleutheronema tetradactylum), mackerel (Rastrelliger sp.), threadfin bream (Nemipterus japonicus), and hairtail (Trichiurus lepturus). We found microplastics in the digestive tract of four selected fishes with a frequency of occurrence of 100%. The concentration of microplastics in fish digestive tracts is relatively high, with a value range of 12 ±2.86 to 28.33 ±8.11 particles∙ind.-1. Microplastics were found in films, fibres, fragments, and granule shape types with various colours: brown, purple, blue, black, green, transparent, and yellow. The polymers found were polystyrene (PS), nylon, acrylonitrile butadiene styrene (ABS), polyurethane (PU), polypropylene (PP), high-density polyethylene (HDPE), and low-density polyethylene (LDPE). The present study provides baseline data for microplastics contamination in commercial fish species landed at Lengkong Fish Auction Point, Cilacap, Central Java, Indonesia. The fact that we discovered PU, the most harmful polymer, piques our attention.

Opis:
The study evaluated the adsorption potential of white cedar sawdust (WCS) for dye removal. WCS was chosen from five preferred, abundant waste biomasses from Pakistan. Various parameters such as contact time, adsorbent dose, dye concentration, pH, and particle size were optimized for methylene blue (MB) dye adsorption. The adsorbent was characterized by FTIR, SEM, EDX and BET analyses. The surface area of the adsorbent was 1.43 m2·g-1 and pore volume was 0.000687 cm3·g-1. The adsorption data best fitted the isotherm models of Langmuir, Temkin, Dubinin–Radushkevich, and Freundlich. The maximum experimental adsorption capacity obtained was 55.15 mg·g-1, which was in close agreement to the calculated adsorption capacity. Fitness of the pseudo-second order kinetics suggested chemisorption as the rate-limiting step. Thermodynamic study for adsorption was carried out to evaluate the Gibbs free energy (ΔG°), enthalpy (ΔH°) and entropy (ΔS°). The negative values ΔG° at the examined temperature range confirmed the spontaneous adsorption of MB onto WCS.

Opis:
An ergonomic assessment of the involvement of static muscular forces like back strength, grip strength and pinch strength in different occupations was made. A study was conducted on 45 normal adult males (15 subjects per group) which included video display terminal (VDT) operators, industrial workers and safety inspectors. Their maximum back strength, handgrip strength and pinch strength were measured with dynamometers. The observed values of back strength were significantly lower in VDT operators while significantly higher in safety inspectors and moderate in industrial workers. The values of grip strength and pinch strength of all sample groups were more or less similar. The findings clearly indicate that static muscular strength varies significantly in different occupations. Heavy static muscular load might lead to an accumulation of metabolic waste and toxins on the back resulting in lower back strength in VDT operators and industrial workers.

Visual and auditory simple reaction times for both right and left hands of young university male students were recorded with a simple reaction timer, before and after an exercise schedule without and with elevated temperatures in a climatic chamber. The results indicated a decrease in both visual and auditory reaction times after the exercise, but a marked increase in them was noticed when exercise was performed at elevated temperatures. The difference in reaction times in preferred and nonpreferred hands was negligible at rest, i.e., without any exercise and elevated temperature. However, the difference was significant when exercise was performed at elevated temperatures. Visual reaction time was longer than auditory reaction time in all conditions. The results suggest that in hot industries, increased temperature has a specific rather than general effect on cognitive processes, perception and attentiveness, leading to increased chances of human errors, fatal accidents and loss of productivity.
