Application of magnetic method to characterize Abaya campus building site, Southern Ethiopia

A geophysical survey involving magnetic method is conducted using ENVI-MAG proton precision magnetometer. The study is carried out with the aim of identifying the possible geological structures which may responsible for the failure of engineering structures. Three traverses having east –west orientation with a ten meters profile spacing and a readings station spacing and one traverse across the three traverses and randomly collected magnetic data were used. At each station three readings were taken and averaged out in order to increase the accuracy of data and diurnal and geomagnetic corrections were made. With the corrected data different anomalous maps were produced like total magnetic field anomaly map, residual magnetic anomaly map and analytical signal map using Oasis montaji6.4 software for further interpretation. The result of this research has shown that the area is affected by different geological structures which may be the cause for the crack and the failure of the building in the area.

ZbSR: A Data Plane Security Model of SR-BE/TE based on Zero-Trust Architecture

Facing the untrusted threats of network elements and PKI/CA faced by SR-BE/TE(Segment Routing-BE/TE) data plane in the zero-trust network environment, firstly, this paper refines it into eight specific security issues. Secondly, an SR-BE/TE data plane security model ZbSR(ZTA-based SR) based on zero-trust architecture is proposed, which reconstructs the original SR control plane into a "trust-agent" two-layer plane based on 4 components of the controller, agent, cryptographic center and information base. On one hand, we distinguish between the two segment list generation modes and proposes corresponding data exchange security algorithms, by introducing north-south security verification based on identity authentication, trust evaluation, and key agreement before the terminal device establishes an east-west access connection, so reliable data exchange between terminal devices can be realized. On the other hand, for the network audit lacking SR-BE/TE, a network audit security algorithm based on solid authentication is proposed. By auditing the fields, behaviors, loops, labels, paths, and SIDs of messages, threats such as stream path tampering, SID tampering, DoS attacks, and loop attacks can be effectively detected. Finally, through the simulation test, the proposed model can provide security protection for the SR data plane with a 19.3% average incremental delay overhead for various threat scenarios.

Digital library services to support online learning amid COVID-19: a study of a private university library in Bangladesh

Purpose The purpose of this paper is to discuss the East West University Library’s (EWUL’s) response to COVID-19 situation through their transformation to digital services. The paper tries to explain how these digital library services support the user community of East West University (EWU) in online teaching and access to information resources. Design/methodology/approach This paper describes the EWUL’s several digital services that are used to meet the needs of its user community during the COVID-19 pandemic. The reflective practice approach has been undertaken for this study on the basis of the authors’ personal experiences working at an academic library. The authors used the reflective practice approach to assess the library’s practice during crisis situation, make the use of technological interventions in service providing and also to re-innovate the digital services for future. Findings During the pandemic, the library shifted all the possible physical or on-site services to digital services, i.e. online resource facilities and remote access to these, federated searching, Web online public access catalog, engaging users through social media, specialized knowledge space, online document delivery, article on request, information literacy training, virtual reference service, etc. The user engagement in all these services is also notable. Research limitations/implications The nature of this study is limited to the COVID-19 pandemic and within a particular geographic location. Practical implications This paper has implications and possible applications for other university libraries in developing countries, which intends to transform their services into digital for ensuring better service quality for their respective user community. Originality/value This paper makes a valuable contribution to the literature on how a private university library of a developing country is responding to pandemics such as COVID-19.

“East West, Home’s Best”: Feminist Politics of Sue Townsend in Bazaar and Rummage

This paper discusses the social reasons for agoraphobia as a psychological disorder as observed in the women characters of British playwright Sue Townsend’s issue-based play Bazaar and Rummage (1982). The depiction of three agoraphobic women in a context characterised by patriarchal dominion constitutes the core of Townsend’s play. Although their problematic condition is presented rather comically, from their accounts, it seems apt to argue that societal oppression is the reason for their longlasting seclusion and constant fear of the outside world. The play offers a rummage sale as an opportunity for women to step outside and conquer their fear. Accordingly, in terms of presenting the psychological condition of women characters and associating the possible solution to their problem with a market occasion, Townsend’s play illustrates an example of feminist criticism. In this study, the play’s analysis is based on the 1980s context dominated by Thatcher politics, and Townsend’s portrayal of agoraphobia is discussed as a criticism of her society in which patriarchal hegemony plays a central role in women’s forced confinement.

Workplace Well-being: An Experimental Investigation into Benefits of Consciousness-based Architecture

Consciousness is primary and unbounded and can be accessed through multiple modalities, including the qualities of the workplace environment. This research explored the proposition that a consciousness-based architecture could improve workplace well-being. It experimentally investigated the potential benefits of Maharishi Vastu Architecture® (MVA) in a business setting. MVA buildings deal with wholeness and the establishment of the parts in relation to the whole. They have a strict East-West directional orientation, and strict proportion and placement of its center and rooms, among other features. A technical consulting company relocated their offices from a conventional building into one designed according to the principles of MVA. All the available employees of the company were tested one month before and one month after the move to the MVA building using a Workplace Well-being Index specifically created for this research. Data analysis comparing the pre and post measurements showed a 8% improvement (p<0.05) in subjective well-being upon relocating to the MVA building. Organizations can thus enhance workforce well-being through holistic workplaces designed for development of consciousness.

Iron Silk Road Trans-Caspian East-West-Middle Corridor Initiative and Baku-Tbilisi-Kars Railway Line

The East-West Middle Corridor (Middle Corridor) with the Caspian Transit, which starts from Turkey with the Baku Tbilisi Kars Railway line, reaches the Caucasus region. From here it travels over the Caspian Sea through Turkmenistan and Kazakhstan to Central Asia and China and is one of the most important components of historical silk road resuscitation project. With this study, the contribution of Baku Tbilisi Kars railway line and Kars Logistics Center, which is the European and Turkish gateway of the middle corridor, to the silk railway in terms of international leasing is explored.

Earthquake source parameter estimation using synthetic waveform modelling

Fault plane solutions and focal depths for three crustal events occurring in the Himalayan collision zone have been obtained using synthetic waveform modelling. Two crustal events with their epicenters in the Tibetan plateau show large component of normal faulting with east-west trading T-axes. The third event with It’s epicenter north of Main Boundary Thrust (MBT) shows reverse faulting with the nodal planes paralleling the local structural trend. All the three crustal events studied have occurred at shallow focal depths of less than 15 km. The Inferred source parameters of these events are discussed In the light of active tectonics of the region.

Earthquake slip vectors in the Himalayan thrust Zone and their tectonic implications

Slip vectors of thirty-nine thrust events occurring along the Himalayan collision zone have been compared with the velocity vectors between the Indian-Eurasian plates derived from the RM 2 and NUVEL 1 models, The observed deviations of the slip vector from the velocity vector have been interpreted in terms of a simple kinematic model according to which the eastern and western blocks of south Tibet are separating from each other, From the model it is estimated that the western and eastern blocks of Tibet are moving at the rate of 3.6 cm/year westwards at 76°Eand 2.6 cm/year eastwards at 94°E with respect to Eurasia respectively, resulting in an east-west extension, projected to the trend at 85°E, at the rate of 5, 5 cm/year. This would correspond to a strain rate of about 6.9 x 10-8year in central Tibetan region.
