Published: April 2021

Abstract
Water as vital needs to our life must be fulfilled. Increasing population tends to water scarcity causes by the high demand and limited source. Water reuse is one of the solutions to face the challenge. Helminth eggs is one of the parameters for water reuse recommended by WHO. Previous studies have shown that there are helminth eggs presence in irrigation water and wastewater system in Indonesia, thus the possibility of disease by helminth eggs presence. This study was conducted to give an advice about the importance of helminth eggs assessment in Indonesia for better water reuse and prevent disease like soil-transmitted helminthiases. To detect the presence of helminth eggs in water, adaptations from several existing methods is required. Indonesia needs an exact method to determine the presence of helminth eggs. Government, institutions, and society have to collaborate to prevent the existence of helminth eggs for the water reuse purpose in the future. This can lead to increase quality of health and environment aspects.

Published: April 2021

Abstract
Pollutant parameter that often exceed the standard is turbidity, then the turbidity parameter was the main concern in this research. The electrocoagulation method is an alternative for treating water without using chemicals. This study aims to reduce the turbidity and develop previous research on electrocoagulation methods into a pilot scale with a flow rate of 0.01 L/sec. The flow rate 0.01 L/sec illustrates the water requirements for one household. In this study the electrocoagulation method was tested by the variation of electrode plates 1, 2 and 3 pairs with 3, 5, 7 and 10 Volts to treat artificial sample water with an initial turbidity of 100 NTU made from sample of raw water from Cikapundung River as one of main drinking water sources in Bandung. The optimal conditions obtained in the preliminary study were retested with turbidity variations of 25, 50, 100, 200, 300 and 400 NTU. The optimal condition of the electrocoagulation process is obtained in the variation of 2 pairs of plates with a voltage of 7 Volts and current density 23.53 A/m2. The variation can treat raw water with an initial turbidity up to 400 NTU until it reaches a quality standard with a final turbidity of 3.40 NTU and the percentage of removal is 99.15%.

Published: April 2021

Abstract
The article deals with the problem of drinking water supply to population. The water supply sources of Azovsky Nemetsky (German) National District of the Omsk Region are characterized in the research. The Irtysh River is the main source of drinking water supply. In general, the studied district is situated in the territory with a shortage of fresh groundwater. Currently, the water supply to Azovsky Nemetsky (German) National District settlements is provided by a complex of hydraulic constructions of the Lyubino-Isilkul and Tavrichesky group water conduits. These pipes take water from the Irtysh River as part of water intake and treatment facilities, water pipelines and a pressure distribution network. In addition to the generally accepted water supply from the group water conduit we define the aquifers of the lower Miocene deposits of the Abrosimov (N1 ab) and upper Oligocene deposits of the Zhuravsky suites (P3 zr) with water mineralization from 1.3 to 5.4g/l. as the most potentially productive in the period of increasing anthropogenic load within Azovsky Nemetsky (German) National District. In case of their usage for drinking water supply the technology of demineralization is recommended.

Published: April 2021

Abstract
The quality of melt runoff from agricultural fields significantly affects the quality of surface water bodies and their ecosystem services. Currently, methods based on geographic information systems (GIS) are used with aim to reduce the risk of pollution of surface water bodies. Thus do make possible a localization of pollutants sources at rural areas and their transport routes to the water bodies. This paper presents the results of geoinformation analysis of the results of melt runoff sampling as well as cartographic modeling of melt runoff on the territory of the summer field dacha (SFD) of the RSAU-MTAA.
In early April 2018 a specially designed fields monitoring was accomplished. Twenty water samples were taken at the locations of ten catchment’s outlets located within the SFD territory. Chemical analyzes identified 5 inorganic chemical components with high concentration values. Digital elevation model (DEM) of the plot area was generated from UAV data for the analysis of the territory’s topography. Spatial analysis of samples in combination with hydrological analysis of DTM showed differentiation in pollution of snowmelt runoff by catchments. This enabled to identify some catchments as providers of the biggest negative contribution to the quality of melt runoff.

Technology of testing shale reservoirs of Paleogene age on the territory of the Eastern Ciscaucasia
Authors: Saltanova A G , Vasiliev V A , Kerimova E G , Kramarenko V S , Sova V E 
Published: April 2021

Abstract
The article demonstrates the technology of testing reservoir layers represented by fractured clay-carbonate rocks in the Eastern Ciscaucasia. Practice shows that if the saturation of permeable rocks is uniform, the reliability of the tests can be ensured if the tested interval does not exceed 25 m. The probability of obtaining an inflow during tests significantly decreases with the increase in the amount of repression of the washing liquid and the duration of its impact on the reservoir. This is caused by clogging of the near-well zone of the reservoir, which results in the hydrodynamic connection of the reservoir with the well deteriorates. Test results are the most reliable if they are performed no later than 3-5 days after opening the reservoir, however, even in this case, the reservoir may be contaminated. For high-quality testing of reservoir layers represented by fractured clay-carbonate rocks, the following processes are required: to make an individual selection of the depression on the formation, to have a priori accurate information about the strength characteristics of the well walls.

Copulatory Signaling and Polygamy of Glassy-Winged Sharpshooters (Hemiptera: Cicadellidae)
Authors: Gordon Shira D , Krugner Rodrigo 
Published: April 2021

AbstractFinding a partner to mate with may be only part of ensuring successful siring of offspring. Females often exhibit cryptic female choice (CFC) during or after copulation, which can influence whose sperm from her multiple partners is chosen for egg fertilization. Known behavioral mechanisms for CFC include assessment of males by their nuptial gifts, duration of copulation, and seminal fluid contents. In this study, the glassy-winged sharpshooter, Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), behaviors during the course of copulation were investigated. Glassy-winged sharpshooter (GWSS) use vibrational communication before copulation occurs. However, little is known about behaviors that occur during and after copulation. Results from this study determined that vibrational signaling also occurs during copulation. Vibrational signals similar to those emitted during precopulatory communication were identified during copulation alongside a new, ‘hum-like’ signal that typically occurred within 10 s after the pair joined in copulation. In addition, results determined the duration of copulation was on average of 15 h, though with a 10-h range (8.5–18.5 h) among observed male–female pairs. Finally, both males and females mated more than once. Collectively, results identified key reproductive parameters required for CFC to occur in GWSS. The study expands on the known animals that use CFC and emphasizes the role that copulatory vibrational communication may play setting the foundations for future more in-depth studies. Understanding of insect behaviors necessary for successful production of offspring is important from an ecological perspective and for development of pest control methods.
Diagnostic Challenges in Children With Congenital Bleeding Disorders: A Developing Country Perspective
Authors: Khaliq Sehar 
Published: April 2021

Abstract

Objectives
To assess the frequency and characteristics of children with inherited bleeding disorders that were initially misdiagnosed, leading to inappropriate disease management.

Methods
This study was conducted at the Haematology/Pathology Department of Fauji Foundation Hospital, Rawalpindi, Pakistan, from August 2014 to August 2018. Children who were diagnosed with an inherited bleeding disorder but did not respond to initial therapy were reevaluated.

Results
In total, 62 children were diagnosed with a bleeding disorder. Of these, 27 were diagnosed with an inherited bleeding disorder and 35 with an acquired bleeding disorder. Of the 27 children with inherited bleeding disorders, 18% (n = 5) were misdiagnosed and treated inappropriately. The median age of the misdiagnosed patients was 9 years (range, 5-13 years). Three patients with Bernard-Soulier syndrome had been misdiagnosed as having immune thrombocytopenic purpura, 1 patient with von Willebrand disease had been misdiagnosed as having hemophilia A, and 1 patient with haemophilia B had been misdiagnosed as having hemophilia A.

Conclusions
There are chances of misdiagnosis and improper or invasive management if comprehensive laboratory evaluation and a thorough clinical evaluation are not performed in children with congenital bleeding disorders.
