The study area is part of the city of Samawa in Al Muthanna Governorate in southern Iraq. The study  area is located to the west of Samawa city bounded by the north latitudes 31⁰11'-31o42' and east longitudes 44o58'- 45⁰16'and its groundwater resources are developed for supply and irrigation purposes. In order to evaluate the quality of groundwater in the study area, twenty three groundwater samples were collected and analyzed for physical and chemical parameters. Hydrochemical analysis showed that the groundwater of the study area is excessively mineralized  and very hard. The increase in flow length of groundwater in the study area caused a change in water quality from bicarbonate to sulfate and chloride. The abundance of the major ions is as follows: SO4> CL>HCO3>NO3and Na>Ca>Mg>K. The dominant type  of groundwater is Na+- sulfate. The water of the  studied wells is not suitable for human drinking. Depending on TDS and EC values, most samples of the water are moderate saline class for irrigation. Most wells are good to permissible (wells No.4,14,17) and doubtful (well No. 12) for irrigation depending on Na%, while unsuitable for irrigation depending on EC  (except well No. 17 which is  permissible). Excellent water class (S1)for agriculture was recorded depending on SAR, except for well N0.2 which had an a good class (S2).

AbstractIn arid areas, the pressure on water resources and in particular on groundwater resources is on the rise, mainly due to increasing demand and the deterioration of water quality. In this context, the present work aims to follow the annual evolution, between 2009 and 2019 of the physicochemical parameters, and to evaluate the quality of groundwater of the region of Mougheul, by determining the data of pH, TDS, conductivity and the concentrations of major ions ( Ca+2, Mg+2, Na+, K+, Cl−, HCO3−, SO4−2, NO3−) of 07 water points. The results revealed that all the levels of the physicochemical parameters do not exceed the WHO potability standards, except high values were observed at the level of well W6 which exceeds the limits recommended by the WHO (50 mg /l). The diagram of Schöeller and Berkaloff shows that the groundwater has the bicarbonate magnesium facies. The representation of the data on the Piper triangular diagram shows that W6 has the facies chlorinated and calcium sulfate and magnesium and the other water points have the facies bicarbonate calcium and magnesium. SAR values show that the groundwater of Mougheul is excellent for irrigation. The classification according to the Wilcox diagram shows that the groundwater of Mougheul in general is good quality, but the well of W6 water is suitable for irrigation and requires monitoring the evolution of salinity.

<p>Este trabalho teve como objetivo avaliar os parâmetros físico-químicos de polpas de fruta produzidas e comercializadas na cidade de Petrolina-PE, tendo como referência a Instrução Normativa nº 1, de 7 jan. 2000, do Ministério da Agricultura que define as características físicas e químicas estabelecendo limites mínimos e máximos específicos para cada polpa de fruta. Foram avaliadas duas marcas (1 e 2) de polpas de abacaxi, cacau, caju, graviola, maracujá e umbu, analisadas quanto aos parâmetros de pH, sólidos solúveis totais (SST), acidez total titulável (ATT), ácido ascórbico, relação SST/ATT e sólidos totais. Os resultados permitem inferir que a marca 2 apresentou qualidade superior na maioria dos parâmetros avaliados quando comparado com a marca 1. Entretanto para alguns sabores de polpa as duas marcas não atenderam os valores padrões. Entre as polpas o único sabor que apresentou os padrões exigidos foi a polpa de caju em ambas as marcas, e a que apresentou resultado de pior qualidade diante dos padrões foi a polpa de maracujá principalmente da marca 1. Dessa forma constata-se que há grandes variações entre as marcas, e entre alguns parâmetros, o que compromete a qualidade das polpas, prejudicando assim o consumidor.</p><p align="center"><strong><em>Physicochemical parameters of fruit pulps produced in Petrolina – PE</em></strong></p><p><strong>Abstract</strong><strong>: </strong>This study aimed to evaluate the physicochemical parameters of fruit pulps produced and marketed in the city of Petrolina-PE, with reference to the Instruction Nº 1 of 7 January 2000 of the Ministry of Agriculture, which defines the physical and chemical characteristics setting minimum and maximum limits specific to each fruit pulp. We evaluated two brands (1 and 2) of pineapple, cocoa, cashew, soursop, passion and umbu fruit pulp, analyzed for pH, total soluble solids (TSS), total titratable acidity (TTA), ascorbic acid, TSS / TTA and total solids parameters. Results show that the brand 2 showed superior in most evaluated parameters when compared to the brand 1. However, for some pulp flavors of both brands did not reached the standards values. Among the pulps, the only flavor that presented the required standards was the cashew pulp in both brands, and presented the results of lower quality on the standards was the passion fruit pulp mainly brand 1. Thus, it appears that there are great variations between brands and between some parameters, which compromises the quality of the pulp, thus impairing the consumer.</p>

AbstractThe aim of this study is to evaluate the hydrogeochemical characteristics and water environmental quality of shallow groundwater in the Suxian mining area of Huaibei coalfield, China. The natural formation process of shallow groundwater in Suxian is explored using Piper trilinear charts and Gibbs diagrams, and by examining the ratios between the major ions. United States Salinity Laboratory (USSL) charts, Wilcox diagrams, and the water quality index (WQI) are further employed to quantify the differences in water quality. The results reveal that the main hydrochemical facies of groundwater are HCO3–Ca, and that silicate dissolution is the main factor controlling the ion content in shallow groundwater. The USSL charts and Wilcox diagrams show that most of the water samples would be acceptable for use in irrigation systems. The WQI results for each water sample are compared and analyzed, and the quality of groundwater samples around collapse ponds is found to be relatively poor.

While self-report of overall quality of life has been widely examined, there are no studies that explore the impact of the relative importance people give to the various categories of their quality of life. Therefore, with a quantitative methodology and a co-relational transverse design, we analyze differences in the assessment when the importance given to each category is evaluated. Participants were 530 students from the city of Antofagasta in the North of Chile, aged between 15 and 18 years. They were from subsidized, public secondary schools and private and state universities in the city who were assessed using the KIDSCREEN-27 questionnaire. Results: Differences were found in the assessment of categories when results were analyzed based on gender and age and when incorporating an assessment of importance. Even when the results were not conclusive, there was evidence of a need to incorporate an importance variable when assessing quality of life.

Port Sudan is the main port and largest commercial centre of the Sudan located in semi-arid region. Population estimate in 2010 was about 926,000 inhabitants and the water demand estimated was about 120000-150000 m3/day. Water production from Khor Arbaat is 60,000 m3/day in good years; however, it may go down to 30,000 m3/day in bad years. In general, the overall situation of the city is characterized by regular shortages. There are three dams (U/G Dam1, SPC Dam2, FR Dam3) structured on Khor Arbaat for water harvesting (2005,2000,1992), siltation represents the greatest problem to these Dams, accordingly their capacities storage is decreases. Their storage capacities are 16*106, 5*106, and 6*106 m3 respectively, therefore the small capacities of these dams lead to inflation silt in a limited period of time. In the same way the Sea Port Corporation (Dam 2) in the year 2012 was removed by the armed forces of the corps as a result of inflation silting and thickness of silting to 6 meters. Water from Khor Arbaat gets into the transfer system without any treatment. The study is carried out to assess and evaluate the quality of surface and ground water resources in the Khor Arbaat zone. Field works included three visits to the study area, on January 2018, February 2018, and on March 2018. Sixteen typical water samples collected from different locations within Khor Arbaat and the city network were analyzed for physical and chemical water quality parameters. GIS Arc. Map and Kriging method are used to study the characteristics of water depend on coordinates and samples results.

Abstract. The characteristics of the Essaouira basin water resources are a semi-arid climate, which is severely impacted by the climate (quantity and quality). Considering the importance of the Essaouira aquifer in the groundwater supply of the region, a study was conducted in order to understand groundwater evolution in this aquifer. The Essaouira aquifer is a coastal aquifer located on the Atlantic coastline of southern Morocco, corresponding to a sedimentary basin with an area of nearly 200 km2. The control of the fluid exchange and the influence of mixing zones between the groundwater and saline water was investigated by sampling from 20 wells, drillings and sources belonging to the Plio-Quaternary and Turonian aquifers. It is hypothesized that groundwater major ions chemistry can be employed to determine the interaction between the groundwater and saline water (coastal aquifers). Groundwater samples examined for electric conductivity and temperature showed that waters belonging to the Plio-Quaternary and Turonian aquifers present very variable electric conductivities, from 900 μs/cm to 3880 μs/cm. Despite this variability, they are from the same family and are characterized by sodium-chloride facies. However, a good correlation exists between the electrical conductivity and chloride and sodium contents. The lower electrical conductivities are situated in the North quarter immediately to the south of the Wadi Ouazzi.

In order to assess the mortality and lethality rates of newborns in obstetric organizations of the North-Western Federal District in 2013–2019, a comparative analysis of official statistics data was carried out. It was found that in the North-Western Federal District in the period from 2013 to 2019, there was an almost annual decrease in newborn mortality rates. The overall decrease in mortality in maternity care organizations of the Federal District (from 2,5% to 1,9%) was mainly due to a decrease in mortality in obstetric hospitals of the first and second levels (respectively from 3,2% to 1,2% and from 1,7% to 0,7%), while most children died in perinatal centers, where the mortality rate has not changed in recent years (2013 – 4,1%; 2019 – 4,0%). The study showed a decrease in mortality rates in the subjects of the Russian Federation that are part of the federal district, except for the city of St. Petersburg. The average hospital lethality rate of newborns in maternity care organizations of the North-Western Federal District during 2013–2019 was in the range of 1,9%–2,0%, did not change significantly and corresponded to the national average. However, the level of hospital lethality significantly differed in individual subjects of the district – in more than half of them, the level of hospital lethality exceeded the average, while in others it was significantly lower. Thus, the decrease in the mortality and lethality rates of newborns in maternity care organizations indicates an increase in the quality of medical care for children in the North-Western Federal District. dicates an increase in the quality of medical care for children in the North-Western Federal District.

The contents of FC, somatic coliphages and F-specific bacteriophages were measured in the stabilization pond and stabilization reservoir system of the City of Arad (Israel) in order to determine the efficiency of the treatment process regarding the microorganisms removal. Monitoring was conducted close to one year. Physical and chemical parameters (temperature, pH, BOD5, COD, SS) were also analyzed with the aim of finding factors that affect the microorganisms removal. The field results prove a very good performance of this treatment system. FC, somatic coliphages and F-specific bacteriophages were removed between 4.16 and 5.76 log units, during winter and in between 6.02 and 6.47 log units during summer. The microbial quality of the final effluent complies with the WHO guidelines for unrestricted irrigation. The results also indicate that retention time and temperature seem to be the most important factors for microorganisms removal. F-specific bacteriophages were removed at higher rates than FC and somatic coliphages. Consequently, it is suggested that F-specific bacteriophages might be less adequate viral indicators for this treatment system.
