In rabi, PM10 and PM2.5 have a significant negative association with (relative humidity) RH and positive association with (air temperature) AT. High AT during pre-monsoon, accompanied by low RH, loosens up soil particles and they can easily disperse. Stronger winds in rabi season promote NO2 and SO2 dispersion. In kharif, lower AT, higher RH and slower winds exist. Both PM10 and PM2.5 have a negative association with AT and (wind speed) WS. With lower temperature and slower winds during winter, pollutants are trapped within the boundary layer and are unable to disperse. As expected, NO2 has a significant negative association with AT in Haryana. However, in case of Delhi, the association is significant but positive, and could be due to the odd-even scheme imposed by the Delhi government. More research is needed to determine the health effects of Haryana’s rabi CRB activities on Delhi.

Hand washing with soap and water is the single most weapon against infectious agents. Proper hand washing is not only reduces nosocomial infection, but also prevents the spread of current global concern Novel Corona viruses (COVID-19) and other viral illnesses like cold and flu. Therefore, the aim of this study is to assess hand washing practice among health care workers in Ethiopia.

In the current meta-analysis, the target variables search from different databases, like Google Scholar, African Journals OnLine, PubMed, and Scopus. All necessary data extracted by using a standardized data extraction format. Heterogeneity across the studies was evaluated using the I

index and Cochran’s Q test. A random effect model computes to estimate the pooled proportion of hand washing practice among health care workers.

In this meta-analysis, we included fifteen observational studies summarize the proportional of hand washing practice among health care workers. In the current study, the pooled hand washing practices among Ethiopian was 57.87% (95% CI 44.14-71.61). Subgroup analysis conduct to identifying the sources of heterogeneity.

The overall pooled proportion of hand washing practice among health care workers was low. Hand washing with water and soap is recommended at least for 20 s to prevent contagious disease like Corona viruses.

A 4-chlorophenol mineralization reaction in a heterogeneous solar reactor with suspended TiO2 and addition of H2O2 with tubular geometry and radiation collectors, fluid flow and a recirculation system was selected as a complex model system in order to validate the approach. The dynamic behavior of the reactor in dimensionless variables was modeled as a function of D a i . Where D a i ( z , t ) is a local property and grouped the optical and surface’s properties of the catalyst, catalyst load, radiation intensity, the photon absorption rate, rate of non-photochemical reactions, the H2O2 effect, the reaction rate of different stages like adsorption, attack of radicals, surface reactions, plus design and operation variables like reactor volume and volumetric flow. selleck chemical A coupling of orthogonal collocation and Runge-Kutta methods were used to solve the PDEs and carry out the simulations to the different experimental conditions, resulting in profiles of D a i , C i , and conversion in function of time and space. The D a i profiles proposed in the new methodology are capable of describing the disturbances in solar reactors, to indicate consumption and generation rates, instantaneous changes of reaction rate, to describe competitive reactions and quenching effects and to determine equilibrium concentrations, all of the above at each time and space. Therefore, this approach is a analysis tool of reactors which complements the concentration profile. This methodology can be extended to other reactive systems, adapting the intrinsic reaction rates.The proximate, minerals, amino acid and fatty acid composition of wild, pond-, gher- and cage-cultured tilapia in Bangladesh were evaluated and varied significantly (p Mn, respectively in all the tilapia and the ratio of Na/K was less then 1. Essential amino acids, leucine (1.47-1.56 g/100 g) and lysine (1.66-1.74 g/100 g), were the predominant amino acids in tilapia, followed by non-essential amino acids, aspartic acid (1.72-1.84 g/100 g) and glutamic acid (2.88-3.07 g/100 g). Saturated palmitic acid (25.4%-35.54%), monounsaturated elaidic acid (31.51%-35.63%) and polyunsaturated linolenic acid (17.69%-22.57%) were the main fatty acids found in tilapia. The desirable protein percentage, Na/K ratio, the presence of essential amino acids, leucine and lysine, n-3 and n-6 fatty acid contents proved that the consumption of wild, pond-, gher- and cage-cultured tilapia are beneficial to human health and could be recommended to prevent different diseases particularly of cardiovascular type.Precast concrete system has been widely used in modern day constructions due to its high efficiency in both production time and cost. However, because of the way it is constructed (with flat and dense surface), problems with sound reflection and transmission often exist. It is known that increasing of damping property of materials can reduce the transmission of impact sound and vibration which could lead to an improvement in sound insulation performance. In this study, a type of Viscoelastic Polymer Sheet (VPS) was introduced and attached to concrete precast panels with an aim to improve damping property of precast concrete panels. Seven precast concrete specimens with various patterns and attachment position of VPS were prepared. Effect of patterns and locations of attaching VPS on damping property are investigated and discussed.After the economic liberalization in mid-2000, Tanzania has assumed that tourism growth spars economic growth due to the consistent significant contribution of tourism sector to the country’s annual income. However, there are limited empirical studies that investigated tourism-economic growth relationship in Tanzania. This study aims to investigate an empirical insight into the actual nature of tourism-economic growth in Tanzania by applying the Granger causality and Wald test methods where annual time series data on international tourism receipt, real Gross Domestic Product, and real effective exchange rate over the period 1989-2018 are used. Further, the Impulse Response Function approach is utilized to provide insight into the qualitative nature of the relationships and the length of time necessary for the causal effect to take place. The findings confirm a unidirectional causality from tourism development to economic growth. The study concludes that Tanzania ought to focus on economic strategies that encourage sustainable tourism development as a feasible source of economic growth.
