SynopsisReactivity trends of thioethers toward square-planar complexes can be generally interpreted by use of an equation of the form: log k = γ + α∑σ* + βθ, where k denotes second-order rate constants, ∑σ* the sum of Taft constants for the thioether substituents, and θ the thioether cone angles. γ represents an intrinsic parameter for each substrate complex, while α is an electronic and β a steriSynopsisReactivity trends of thioethers toward square-planar complexes can be generally interpreted by use of an equation of the form: log k = γ + α∑σ* + βθ, where k denotes second-order rate constants, ∑σ* the sum of Taft constants for the thioether substituents, and θ the thioether cone angles. γ represents an intrinsic parameter for each substrate complex, while α is an electronic and β a steri

In wireless sensor/ad hoc networks, all wireless nodes frequently flood the network channel by transmitting control messages causing “broadcast storm problem”. Thus, inspired by the physical backbone in wired networks, a Virtual Backbone (VB) in wireless sensor/ad hoc networks can help achieve efficient broadcasting. A well-known and well-researched approach for constructing virtual backbone is so

It is widely accepted that climate change may be contributing to population movement and has gendered effects. The relationship between climate change as a direct cause of migration continues to give rise to debates concerning vulnerabilities, while at the same time gendered dimensions of vulnerabilities remain limited to binary approaches. There is limited cross-fertilization between disciplines

The impact of climate change on the production of hydropower in Mozambique is reviewed and regression analysis is applied to evaluate future climate scenarios. The results show that climate change will cause increased variability of precipitation and create flooding that can damage infrastructure such as hydropower dams. Climate change can also cause drought that will decrease surface water and re

The Syrian conflict is far from over and the return of Syrian refugees is not indicative of mass influx into the country. Syrian refugees and their return have been instrumentalised and used as a politicai card and refugees should not be forced to return, as this would lead to further displacement and turmoil. Effective and consistent policies based on human rights, justice and accountability must

African countries such as Nigeria are anticipated to be more susceptible to the impacts of climate change due to reliance on rainfed agriculture. In this regard, the impacts of climate change on crop water requirements (CWR), yields and crop water productivity (CWP) of soybean in the Ogun-Ona River Basin, Nigeria, were evaluated for the baseline period (1986–2015) and future period (2021–2099) und

The Islamic State group (IS) has grabbed the world’s attention as one of the most dangerous and gruesome terrorist organizations in history. The group has been studied from different disciplines such as political science, history, and theology. Michael Krona and Rosemary Pennington’s edited volume, The Media World of ISIS, is an attempt by media studies scholars to explore different aspects and di

During the last decade, an active line of research in proof complexity has been to study space complexity and time-space trade-offs for proofs. Besides being a natural complexity measure of intrinsic interest, space is also an important issue in SAT solving. For the polynomial calculus proof system, the only previously known space lower bound is for CNF formulas of unbounded width in [Alekhnovich

The discourse of the Yemeni TV broadcasters has undergone major changes since the Arab Spring in 2011. Moreover, since the outbreak of Civil War in 2015, this discourse has been diverse and has become a clear reflection of the contexts in which it is produced. This article analyses Yemeni media discourse by analysing the titles of news reports published on YouTube by five Yemeni TV channels belong

Decrease of saline lakes, which comprise 44% of all available lake water, is a major concern. It additionally accelerates the desertification process of the region. Thus, various countries have taken different actions in protecting their lake water levels. The aim of this paper is to assess different strategies directed to tackle the decreased lake water levels in Lake Urmia and the Aral Sea, whic

Water security, a key policy objective for sustainable development, is under stress as a result of land use and climate change, especially in (semi-)arid areas like Iran. Land use change alters surface runoff and affects basin-wide hydrological processes and water consumption, while climate change modifies precipitation and temperature patterns and consequently evapotranspiration and water supply.

Recent "peace" deals between Israel and Gulf Arab states herald not a more just and harmonious region, but a more militarized, securitized, and repressive one

Beginning in December 2010, the Arab world was hit by huge anti-government revolutionary waves, popularly known as the Arab Spring. In Syria, the uprising did not take long to morph into a bloody war with international and regional powers wrestling for geopolitical influence and economic gain. The war has significantly changed Syria in terms of politics, economy, and culture. While the first two h

The discourse of the Yemeni TV broadcasters has been undergoing major changes since the Arab Spring in 2011. However, after the recent civil war, specifically since 2015, this discourse has been diverse, and has become a clear reflection of the contexts in which it is produced. This paper attempts to analyze the Yemeni media discourse by analyzing the titles of the news reports published on YouTub
