Integration of geophysical, hydrogeological and geospatial analysis for groundwater assessment in Chotanagpur Granite-Gneiss Complex, Ranchi
Authors: Kumar Gaurav , Kumar Dewashish , Warwade Pratibha
Published: June 2021

Integrated study combining electrical resistivity tomography, geology,
hydrogeomorphology, and weighted overlay analysis of various surface and
subsurface thematic layers proved to be a very useful tool for
evaluating the heterogeneous hard aquifer systems for groundwater
assessment and development. A comprehensive study was carried out at
representative and varied geological settings viz., Chotanagpur
Granite-Gneiss Complex (CGGC), Ranchi has been accomplished from geology
and geophysical datasets. The electrical resistivity tomography results
revealed potential target zones at three sites in the study area up to a
maximum of 170 m depth with a large variation in aquifer resistivity
ranging from 80 to 800 Ω.m. These significant findings depicted a good
correlation and are validated with the lithology in the surrounding of
the resistivity tomography results. Nevertheless, the weighted overlay
technique act as an essential tool for spatial analysis and
interpretation of potential groundwater zones in the study area as well
as validated the geophysical depth models whereas in-depth study on
geology and hydrogeomorphology provides a detailed hydrogeological
scenario throughout the study area for the long-term sustainability of
the groundwater resources both at a local and in regional scale in the
typical hard rock aquifer system.

Authors: Shrestha Arati , Bhattarai Santosh , Shrestha Binod , Koju Narayan Prasad
Published: June 2021

Pangolins in the genus Manis are nocturnal, burrowing, insectivorous
mammals listed as Critically Endangered or Endangered by the
International Union for Conservation of Nature. Of the eight extant
pangolin species worldwide, two species are found in Nepal: the Chinese
pangolin (Manis pentadactyla) and the Indian pangolin (Manis
crassicaudata). Despite having a great ecological role by controlling
the ants or termite population, little attention has been given to the
conservation interventions of both species of pangolins found in the
Terai region (low land) of Nepal. The present study assesses habitat use
and factors affecting the habitat choice of pangolins in low land
(Terai), Nepal. The research was focused on Amritdharapani community
forest of Chitwan district. Pangolin burrows were used as the indirect
signs of pangolin presence. A total of thirty-nine burrows were observed
at elevations ranging from 301 to 413 m asl. Burrows were frequently
associated with north-west aspects, gentle slope (15º to 20º), moderate
canopy cover (51 to 75%), red-colored soil, and acidic soils with pH
6.5 to 7. The burrows were most common in areas with weak human
disturbance (i.e. 1500 to 1700 m from settlements), 800 to 1200 m from
roads, and with-in 300 m from a water source and with-in 20 m from the
nearest termitarium. This study revealed distance to settlement,
distance to road, soil pH, and canopy cover as major factors affecting
the habitat choice of pangolins in the study area.
Second virial coefficient for the exponent--spline-Morse-spline-van der Waals potential and its application
Authors: Somuncu E. , Mamedov B.A.
Published: June 2021

An analytical expression for the second virial coefficient based on an
exponent-spline-Morse-spline-van der Waals (ESMSV) potential is
presented here for use in defining the thermodynamic properties of rare
gases. Our method is established based on a series expansion of the
exponential function, Meijer function, gamma function, binomial
function, and hypergeometric function. Numerical approaches have
commonly been used for the evaluation of the second virial coefficient
with the ESMSV potential in the literature. The general formula obtained
here can be applied to estimate the thermal properties of rare gases.
Our results for the second virial coefficient based on the ESMSV
potential of He-He, He-Ne, He-Ar, and He-Xe rare gases are compared with
numerical calculations and experimental data, and it is shown that our
analytical expression can be successfully used for other gases.
The clinical importance of microscopic hematuria and hydronephrosis in urolithiasis
Authors: Kokulu Kamil , sert ekrem taha
Published: June 2021

Aim: The aim of this study was to investigate the relationship between
the degree of hydronephrosis and the presence of microscopic hematuria
in patients that presented to the emergency department (ED) with
ureteral stones. Methods: The records of patients who presented to our
ED due to urolithiasis between January 2017 and December 2020 were
retrospectively analyzed. Patients aged 18 years or older who underwent
non-contrast computed tomography (CT abdomen/pelvis) and urinalysis (UA)
and were diagnosed with ureteral stones were included in the study.
Radiology reports were reviewed for stone size, localization, and degree
of hydronephrosis. Patients with and without microscopic hematuria and
the degree of hydronephrosis were compared. Results: A total of 476
patients were included, which consisted of 391 with microscopic
hematuria and 85 without microscopic hematuria. The median stone size
was 4.1 mm in the presence of microscopic hematuria and 5.5 mm in the
absence of microscopic hematuria. Logistic regression analysis was
performed to determine the factors associated with the development of
hydronephrosis. Stone size [odds ratio (OR):2.15, 95% confidence
interval (CI):1.12-4.16, p<0.001), presence of pyuria (OR:
2.58, 95%CI: 1.78-3.48, p<0.001), and absence of microscopic
hematuria (OR: 1.31, 95%CI 1.04-2.89, p=0.017) were identified as risk
factors for moderate and severe hydronephrosis. Conclusion: We consider
that non-contrast CT imaging is necessary for the diagnosis and
treatment of emergency cases in which microscopic hematuria is not
detected in urinalysis since their stone size may be larger and degree
of hydronephrosis may be more severe.
Groundwaters of the "Valjevo karst" area (Western Serbia)
Authors: Dokmanovic Petar , Marinovic Veljko
Published: June 2021

?Valjevo karst? is an area of about 780 km2 in a broader sense, while the uncovered karstified limestone makes about 330 km2. It is a part of the Inner Dinarides (Western Serbia). In the litho-stratigraphic view, the karstified limestones of Middle?Upper Triassic dominate, in which karst aquifers are formed. Analysis and systematization of the available data of hydrogeological and other relevant research is carried out. A branched network of groundwater traces between swallow holes and discharge points is presented as well as main features of sixteen karst springs (or scattered discharge zones) and nine (group of) wells, divided into five sectors. Average karst aquifer discharge of the whole area is calculated on 5.18 m3/s. Total minimum flow rate of the analysed karst springs and discharge zones is estimated at 1.2 m3/s, while the total flow rate of the analysed wells is estimated at about 0.3 m3/s, which makes about 1.5 m3/s of total (minimum) discharge. All analysed waters are low-mineralized (<1 g/l), while temperatures range from 9?35 ??. Use of the waters is multipurpose: municipal and local water supply, commercial bottling, recreational pools etc.

Authors: Tojiboyev Nuriddin , Appelbaum Deniz , Kogan Alexander , Vasarhelyi Miklos A.
Published: June 2021

The purpose of this instructional resource is to explain how Structured Query Language (SQL) queries can help auditors to independently retrieve properly formatted data as audit evidence or for further analyses. It demonstrates data extraction using Microsoft (MS) Access, one of the simplest SQL-compliant database software applications. We use a dataset fragment that is extracted from the publicly available enterprise datasets provided by Walton College (University of Arkansas) to run SQL queries as a part of audit investigations. Data extraction is the first step of Extract, Transform, and Load (ETL) and may be time-consuming. We demonstrate how SQL queries can assist with this task, thereby allowing the auditor to begin analysis sooner. This instructional resource can be used to prepare future auditors for the emerging data-rich and technology-driven business environment.

Published: June 2021

OBJECTIVE

Weight loss achieved with very-low-calorie diets (VLCDs) can produce remission of type 2 diabetes (T2D), but weight regain very often occurs with reintroduction of higher calorie intakes. In contrast, bariatric surgery produces clinically significant and durable weight loss, with diabetes remission that translates into reductions in mortality. We hypothesized that in patients living with obesity and prediabetes/T2D, longitudinal changes in brain activity in response to food cues as measured using functional MRI would explain this difference.

RESEARCH DESIGN AND METHODS

Sixteen participants underwent gastric bypass surgery, and 19 matched participants undertook a VLCD (meal replacement) for 4 weeks. Brain responses to food cues and resting-state functional connectivity were assessed with functional MRI pre- and postintervention and compared across groups.

RESULTS

We show that Roux-en-Y gastric bypass surgery (RYGB) results in three divergent brain responses compared with VLCD-induced weight loss: 1) VLCD resulted in increased brain reward center food cue responsiveness, whereas in RYGB, this was reduced; 2) VLCD resulted in higher neural activation of cognitive control regions in response to food cues associated with exercising increased cognitive restraint over eating, whereas RYGB did not; and 3) a homeostatic appetitive system (centered on the hypothalamus) is better engaged following RYGB-induced weight loss than VLCD.

CONCLUSIONS

Taken together, these findings point to divergent brain responses to different methods of weight loss in patients with diabetes, which may explain weight regain after a short-term VLCD in contrast to enduring weight loss after RYGB.

En la literatura se han estudiado los múltiples beneficios de tener un animal de compañía. Sin embargo, en ciertos países aún no se logran niveles exitosos de aplicación de manejos de tenencia responsable. Todavía no existen herramientas validadas para evaluar los niveles de tenencia responsable de estos animales, lo cual dificulta la comprensión y abordaje de esta problemática. El objetivo de esta investigación fue desarrollar una herramienta de medición válida de las prácticas de tenencia responsable de los tutores de perros. Para esto, se aplicó un cuestionario online a 1281 propietarios de perros en Chile. Para validar el instrumento, se realizó un análisis de confiabilidad con la muestra de 1065 participantes. Esta reveló que el coeficiente alfa de Cronbach es de 0.651. Se ha demostrado que esta herramienta puede ser utilizada para evaluar las prácticas de tenencia responsable, ya que tiene una consistencia interna aceptable para este tipo de variables.
