Rainwater harvesting: a means of ensuring groundwater resources of the Barind, NW Bangladesh
Authors: Sattar Golam Shabbir 
Published: April 2021

The present study focuses on rainwater harvesting for irrigation and homestead purposes. The undulatory Barind Tract (Pleistocene terrace) covers about 7,250 sq. km and is underlain by thick clay-rich palaeosol sequences. Groundwater of this region is used as the only resource to meet the increasing irrigation demand for production of food to nourish over a million people. Thick clay beds at the top of aquifer and discontinuous subsurface proximal recharge areas have significantly reduced both vertical and lateral recharge potential. Groundwater domain of the Barind Tract has also reached a critical state due to low rainfall, scarcity of surface water sources, and unplanned tapping of groundwater by ever-increasing number of tube wells. As a result, overdraft of groundwater is quite evident. The present situation apparently poses a serious threat to the ecosystem of the study area.
To stop further deterioration of groundwater development in the Barind Tract, a rainwater harvesting technique was tested by excavation of ponds at on-farm level. Results of a three-year long experiment demonstrated that an appropriate and timely intervention helps the community to overcome the problem of increasingly acute water shortage. The present study revealed that the rainwater harvesting is very cost-effective and may prevent a potential economic and social disaster of the Barind Tract.
Landslide hazards in eastern Himalayas
Authors: Mitra Arupkumar , Ghosh A. K. 
Published: April 2021

The Himalayas, with extreme variations in relief, are characterised by very steep slopes, harsh (i.e. cold and humid) climate and a dynamic geotectonic setting. These characteristics appear responsible for widespread slope failures and mass movements, which are often accentuated by various human activities. The importance and severity of landslide phenomenon was not recognised until recently because of sparse habitation, remoteness of its occurrence, and limited sphere of influence of the individual slides. During the last few decades, increasing developmental activities, such as unplanned urbanization, communication, dam construction, deforestation, and agriculture, have substantially affected the geo-environment and aggravated the landslide hazard in the eastern Himalayas.
Three sample areas: i) along the National Highway 31 A (the East Sikkim District), ii) in the area of the Rarnmarn Hydroelectric Project Stage II (the Darjeeling District), and iii) in the Kalimpong Municipal area (the Darjeeling District), all within the inner tectonic belt of the Lesser Himalaya, were investigated for preparing LHZ maps on 1:25,000 scale. Landslide hazard evaluation factors (LHEF) were rated for each of the major causative factors, namely lithology, structure, slope morphometry, relative relief, land use, and drainage density, and summed up to obtain the total estimated hazard (TEHD) values for each slope facet. The TEHD values from 0 to 10 were classified into live zones of increasing relative hazard.
Study of a debris torrent in the Dolomites, Italy
Authors: Biscuola Elena , Turrini Maria Chiara 
Published: April 2021

The Dolomites are situated in a region characterised by the presence of widespread debris flows, which originate at the foot of sub-vertical rocky walls and involve the underlying debris talus. These flows are characterised by the scantiness of the planimetric surface in the watershed and, when they are not channelled, by the variability of the courses from one event to another. This paper describes the study of a channelled debris flow or debris torrent, which periodically jeopardises the built-up area of San Vigilio di Marebbe (Bolzano). This town is located on a large alluvial fan formed by the torrents Ermo and Fojed6ra. The beds of both torrents are constantly full of debris, which is partly contained by many dams and mostly carried away by the water that undercuts the banks. The Fojedora, in particular, which until 1971 ran through the town carrying with it considerable amounts of debris, regularly damaged the town. As a result of these incidents, the last part of the course of the Fojed6ra was artificially diverted into the Ermo by the construction of a 4 m high and 320 m long dyke. In this way the flows, which continued to run through the torrent in the following years, were confined in the channel, and the only danger was that posed by the damming of the main channel into which the torrent Fojed6ra-Ermo flows.
The last important event took place on 27 July 1995 following a short but bad cloud burst in the upper reaches. It mobilised a considerable amount of debris and gave rise to a flow, which was contained by the dyke, and temporarily obstructed the main torrent and the valley floor.
The aim of the study was to reveal the mechanisms that might trigger off the flows, to analyse the morphometry of the deposits in order to characterise these deposits in terms of grain size, and to assess the possibility of damage to the infrastructure. The work was carried out in the following phases:
- a historical reconstruction of past events from both historical documents and the "memories" of the oldest inhabitant s of the town:
- a study of the precipitation records of two meteorological stations located near the landslide area; and
- a topographical reconstruction of the flow route in order to map the main morphological elements , such as channels, scarps, banks, and lobes, and to carry out the grain size analysis of sediments.
Detailed mapping of the alluvial fan by mean s of overlaying slope and land use maps was aimed at evaluating whether a possible flow that was not contained by the dyke might reach San Vigilio di Marebbe.
Palaeoseismicity in the Koteshwor area of the Kathmandu Valley, Nepal, inferred from the soft sediment deformational structures

Published: April 2021

Palaeoseisms have left their imprints within the Plio-Pleistocene tluvio-lacustrine soft sediments of the Kathmandu Basin. Recently, a temple foundation excavation at Koteshwor exposed a soft sediment layer with deformation al structures. The deformed horizon ranges in thickness from 60 to 90 cm. It can be separated into the following three zones, from top to bottom, respectively: (1) homogenised zone. (2) ball-and-pillow zone, and (3) basal zone. The shaking forces strongly agitated the topmost soft-sediment layer, and in this process, the sediments wcre mixed-up, producing subsequently the homogenised zone. At Koteshwor, the homogenised zone ranges in thickness from 15 to 20 cm. It is associated in a few places with micro-debris containing carbonised wood fragments. In the ball-and-pillow zone, the ball-and-pillow structures are 35-79 cm long and 11- 35 cm high. The laminae of the ball-and-pillow structures are strongly folded or disrupted and recumbent folds are locally observed. The central parts of the ball-and-pillow structures are mostly homogenised and 2-3 cm long wood fragments are accumulated in a few places at the bottom of these structures. In the basal zone (up to 55 cm thick), sediments are upraised and plastically deformed. A marker layer in the basal zone attests to the simultaneity of compression and extension deformational structures, a combination of structures that excludes the slope failure origin for the soft sediment deformation and that is clearly related to ground shaking during an earthquake.
The fluvio-lacustrine sediments of the Kathmandu Basin consist of a thin alternation of weakly consolidated and cohesionless silty and sandy layers exhibiting rather good sorting. These conditions and physical properties make them suitable for hydroplastic deformation, liquefaction, and/or tluidisation. Previous studies showed that earthquake-induced liquefaction and fluidisation deformational structures are connected with seismics hocks of M>5. The soft sediment deformational structures with a thickness varying between 60 and 90 cm in a lacustrine environment are formed in seismic intensity zones greater than IX. It is therefore interred that the palaeoseism intensity at Koteshwor was larger than the intensities of the 1833 and 1934 historical earthquakes affecting the Kathmandu Basin.

Shadism from the Perspective of Intersectionality in Toni Morrison’s The Bluest Eye
Authors: Nefnouf Ahmed Seif Eddine 
Published: April 2021

This paper aims to discuss shadism from a perspective of intersectionality and how people with a darker skin tone suffered particular forms of discrimination due to the issues of shadism and its interaction with the class, gender, age, ability, and race. Shadism has infused the black society for many centuries, hence outlined during slavery. Shadism is the discrimination against a person with a darker skin tone, typically among individuals of the same racial group. In The Bluest Eye, Toni Morrison describes how African American women and girls like Pecola are considered ugly by her family and the community due to her darker skin tone. in this research paper we are going to explore shadism and examine intersectionality theory like race, gender, sexuality and class, and their influence on dark-skinned black women, through the main character Pecola Breedlove. Using intersectionality theory to understand shadism helps to know that there are different ways a person could face oppression and domination. This paper gives a new vision of shadism which have been studied as amatter of racism, but throughout the intersectionality of the the identity component. The analysis shows that shadism is influenced by race and other aspects of intersectionality such as gender, race, age and ability, and other aspects of identity.

Published: April 2021

BackgroundThe glioma-associated stromal cell (GASC) is a recently identified type of cell in the glioma microenvironment and may be a prognostic marker for glioma. However, the potential mechanisms of GASCs in the glioma microenvironment remain largely unknown. In this work, we aimed to explore the mechanisms of GASCs in gliomas, particularly in high-grade gliomas (HGG).MethodsWe used glioma datasets from The Cancer Genome Atlas (TCGA) and the Chinese Glioma Genome Atlas (CGGA). We utilized the Single-sample Gene Set Enrichment Analysis (ssGSEA) algorithm to discriminate between patients with high or low GASC composition. The xCELL and CIBERSORT algorithms were used to analyze the composition of stromal cells and immune cells. Risk score and a nomogram model were constructed for prognostic prediction of glioma.ResultsWe observed for the first time that the levels of M2 macrophages and immune checkpoints (PD-1, PD-L1, PD-L2, TIM3, Galectin-9, CTLA-4, CD80, CD86, CD155, and CIITA) were significantly higher in the high GASC group and showed positive correlation with the GASC score in all glioma population and the HGG population. Copy number variations of DR3 and CIITA were higher in the high-GASC group. THY1, one of the GASC markers, exhibited lower methylation in the high GASC group. The constructed risk score was an independent predictor of glioma prognostics. Finally, a credible nomogram based on the risk score was established.ConclusionsGASCs stimulate glioma malignancy through the M2 macrophage, and are associated with the level of immune checkpoints in the glioma microenvironment. The methylation of THY1 could be used as prognostic indicator and treatment target for glioma. However, further studies are required to verify these findings.
