The dynamics of a protein and the water surrounding it are coupled via nonbonded energy interactions. This coupling can exhibit a complex, nonlinear, and nonstationary nature. The THz frequency spectrum for this interaction energy characterizes both the vibration spectrum of the water hydrogen bond network, and the frequency range of large amplitude modes of proteins. We use a Recurrence Plot based Wiener–Khinchin method RPWK to calculate this spectrum, and the results are compared to those determined using the classical auto-covariance-based Wiener–Khinchin method WK. The frequency spectra for the total nonbonded interaction energy extracted from molecular dynamics simulations between the β-Lactamase Inhibitory Protein BLIP, and water molecules within a 10 Å distance from the protein surface, are calculated at 150, 200, 250, and 310 K, respectively. Similar calculations are also performed for the nonbonded interaction energy between the residues 49ASP, 53TYR, and 142PHE in BLIP, with water molecules within 10 Å from each residue respectively at 150, 200, 250, and 310 K. A comparison of the results shows that RPWK performs better than WK, and is able to detect some frequency data points that WK fails to detect. This points to the importance of using methods capable of taking the complex nature of the protein–solvent energy landscape into consideration, and not to rely on standard linear methods. In general, RPWK can be a valuable addition to the analysis tools for protein molecular dynamics simulations.

The main GHGs (CO2, NOx, and SO2) have been quantified based on national energy and population statistics. The results show that the contribution of households' energy consumption in the West Bank to global CO2 emission is about 0.016%, while contribution of total energy consumption by all sectors is about 0.041%. The results show that wood is the most polluting energy source in terms of CO2 and NOx emission, while electricity is the most polluting source in terms of SO 2. Other sources like diesel, kerosene, and LPG that contribute to the GHGs emission are also quantified. The total amounts of CO2, NOx, and SO2 by households in the West Bank are 4.7 million tonne per year, 3.02 thousand tonne per year, and 2.23 thousand tonne per year respectively. This study presents a set of measures that might help in reducing the level of GHGs emission and protect the environment. © 2013 Elsevier Ltd. All rights reserved.

The dimerization rate of the bacterial cell division protein FtsZ is strongly affected by the intracellular crowding. Yet the complexity of the intracellular environment makes it difficult to investigate via all-atom molecular dynamics or other detailed theoretical methods. We study the crowding effect on FtsZ dimerization which is the first step of an oligomerization process that results in more elaborate supramolecular structures. In particular, we consider the effect of intracellular crowding on the reaction rates, and their dependence on the different concentrations of crowding agents. We achieved this goal by using Brownian dynamics (BD) simulation techniques and a modified post-processing approach in which we decompose the rate constant in crowded media as a product of the rate constant in the dilute solution times a factor that incorporates the crowding effect. The latter factor accounts for the diffusion reduction and crowder induced energy. In addition we include the crowding effects on water viscosity in the BD simulations of crowded media. We finally show that biomolecular crowding has a considerable effect on the FtsZ dimerization by increasing the dimerization rate constant from 2.6 × 107 M-1 s-1 in the absence of crowders to 1.0 × 108 M-1 s-1 at crowding level of 0.30. © 2014 Elsevier Inc.

In this first paper in a series of four papers on midwifery, we aimed to examine, comprehensively and systematically, the contribution midwifery can make to the quality of care of women and infants globally, and the role of midwives and others in providing midwifery care. Drawing on international definitions and current practice, we mapped the scope of midwifery. We then developed a framework for quality maternal and newborn care using a mixed-methods approach including synthesis of findings from systematic reviews of women's views and experiences, effective practices, and maternal and newborn care providers. The framework differentiates between what care is provided and how and by whom it is provided, and describes the care and services that childbearing women and newborn infants need in all settings. We identified more than 50 short-term, medium-term, and long-term outcomes that could be improved by care within the scope of midwifery; reduced maternal and neonatal mortality and morbidity, reduced stillbirth and preterm birth, decreased number of unnecessary interventions, and improved psychosocial and public health outcomes. Midwifery was associated with more efficient use of resources and improved outcomes when provided by midwives who were educated, trained, licensed, and regulated. Our findings support a system-level shift from maternal and newborn care focused on identification and treatment of pathology for the minority to skilled care for all. This change includes preventive and supportive care that works to strengthen women's capabilities in the context of respectful relationships, is tailored to their needs, focuses on promotion of normal reproductive processes, and in which first-line management of complications and accessible emergency treatment are provided when needed. Midwifery is pivotal to this approach, which requires effective interdisciplinary teamwork and integration across facility and community settings. Future planning for maternal and newborn care systems can benefit from using the quality framework in planning workforce development and resource allocation. © 2014 Elsevier Ltd.

This article discusses the possible impact of global crisis on the economic and social rights of Palestinian refugees in host Arab countries. While the impact of global crisis is not felt only by refugees, this article will only address the case of Palestinian refugees in the Arab states that host the majority of Palestinian refugees; that is, in Egypt, Jordan, Lebanon, and Syria. Historically speaking, crisis (political, economic and social) at the national, regional and international levels has had a negative impact on Palestinian refugees, not only in terms of political enforcement but also in terms of their legal recognition. Accordingly, there are no grounds to believe things will be different with the current global financial crisis. It may even be worse, given the natural increase in the number of Palestinian refugees in Arab countries and, accordingly, in their needs.The reasons behind this difficult situation will be discussed in detail, including what is commonly referred to as the 'protection gap' for Palestinian refugees in host Arab states, on the international and regional level; the lack of clear legal texts providing and protecting basic rights; and the inclusion of discriminatory legal texts in the constitutions of Arab states. These matters may partly explain why the status of rights for Palestinian refugees in host Arab states is more fragile than for other categories of persons.This article will also argue that political enforcement, effectuated by concerned countries or by international organizations, without legal recognition gives such actions the status of charitable acts, rather than the fulfillment of legal obligations. It is only in the case of legal obligations that rights become justiciable and states, as much as international organizations, become accountable. The nature of assistance provided to Palestinian refugees by concerned states proves that it is far from being considered as their legal obligation. As a consequence, such assistance is dependent on the resources and political willingness of donor communities for voluntary contributions. Accordingly, the negative impact of the financial crisis will be felt by Palestinian refugees, and donor communities are likely to offer humanitarian aid rather than development.Finally, the article argues that the deterioration in the global economic context is no justification for states - whatever their level of income - to compromise on their fundamental human rights obligations. In such times it is even more important that states guarantee minimum essential levels of human rights; take deliberate measures targeted at the most vulnerable; avoid measures that are retrogressive or discriminatory; and orient public policy towards the progressive realization of the rights of the whole population through the equitable distribution of available resources. © The Author (2011).

This paper describes the kinetics and mechanism of oxidation of several monohydric alcohols to the corresponding aldehydes and ketones by bis(quinuclidine)bromine(I) bromide in the presence of pyridinium trifluoroacetate. All evidence from the thermodynamic parameters, deuterium kinetic isotope effect, and Hammett reaction constants supports a two-step mechanism and suggests that the transfer of hydride ion from the substrate to the oxidant is the rate-determining step. © 2012 Springer-Verlag.

Water Resources Management | Year: 2012

Water resources in the Middle East are under enormous stress, due to an increase in population growth and the extensive use of water resources, which exceeds the water demand in this regional bloc. Moreover, climatic changes pose another dimension of stress on water resources; these changes have significant environmental, social, and economic effects. In fact, the governance of these countries has the tendency of increasing this stress or decreasing it, depending on its performance and efficiency in applying policies, legislation and managerial plans towards decreasing the poverty and the vulnerability of the countries specially those suffering from poverty. In this paper, the vulnerability of five countries-Israel, Jordan, Lebanon, Palestine and Syria-will be assessed based on the extent of climate changes and the type of climate governance and their effects on water resources. This paper will introduce a new index, which will be called the Governance and Climate Vulnerability Index (GCVI). The index will measure the vulnerability of each country vis-à-vis water-related issues, while taking into account governance and climatic indicators. The vulnerability of these countries will also be ranked, for purposes of comparison. This paper concludes with the recommendation for governments to develop appropriate water resources management and to improve their environmental policies, including raising awareness on multiple levels. These strategies are expected to lead to decreased vulnerability to climatic changes. © 2012 Springer Science+Business Media B.V.

The dynamic cross-correlation Map(DCCM) technique has been used extensively to study protein dynamics. In this work, we introduce the use of the method of correlation of probability of recurrence (CPR) as a complementary method to detect correlations between protein residue atoms. Time series of the distances of the Cα atoms of the β-lactamase inhibitory protein (BLIP) from a reference position are analyzed using CPR and mutual information (MI). The results are compared to those provided by DCCM. In comparison to MI, CPR is found to detect more of the correlations present in DCCM. It is also able to detect a small number of significant correlations between distant residues that are not detected by DCCM. © 2014 Wiley Periodicals, Inc.

"Azmeh," which means traffic jam in Arabic, and "Qalandiya," the name of a major Israeli checkpoint on the outskirts of Jerusalem, join a slew of other global traffic apps, including the Israeli-developed Waze. What sets the two Palestinian apps apart is how they go beyond daily rush hour traffic and touch at the heart of a central Palestinian criticism of Israeli occupation. The free apps, launched over the last month, are still in their infancy, with only a few hundred downloads each. But as they grow in popularity, their developers say the crowdsourced apps present a partial solution to the jams that checkpoints cause, and they hope will catch on with drivers. "The occupation affects the Palestinian people from all aspects, and takes from them lots of rights. One of those rights is the freedom of movement," said Basel Sader, 20, a Palestinian resident of east Jerusalem and a law student at Jerusalem's Hebrew University who developed Azmeh. "This application can't give them the freedom of movement but it can make things easier for them." Israel operates a series of checkpoints that dot the West Bank and separate it from Israel, restricting travel for Palestinians on a number of roads. When tensions are heightened, a 120-mile (200-kilometer) jaunt from the southern tip of the West Bank to the north can become a complicated journey that could take hours. Checkpoints pose particular problems for Palestinians who want to enter Israel for jobs, family visits, medical care or to pray. Israel says the restrictions are meant as a security measure, and officials note that the number of military checkpoints has been greatly reduced as violence has subsided over the last decade. But Palestinians see the limits on movement as a form of collective punishment that disturbs their routine and can often include intrusive and humiliating searches by guards. In contrast, Israeli settlers can travel freely in and out of Israel and pass quickly through military checkpoints set up to protect their communities. Palestinians need permits to enter Israel, as well as Israeli-annexed east Jerusalem, and must pass through Israeli-controlled border crossings to enter neighboring Jordan. This dual treatment also affects Palestinian travel inside the West Bank. Well-maintained, high-speed roads serve settlements and connect them to each other and Israel. Palestinians are not expressly barred from using these roads, but the highways usually bypass Palestinian communities. Many of the roads connecting Palestinian areas are decrepit and in poor condition. In times of conflict, Israel also puts up additional military checkpoints that can slow or halt movement between Palestinian towns. The apps could relieve a bit of that burden. For now, they are used mainly for checkpoints separating Israel and the West Bank, where drivers are often stuck for hours in a tangle of traffic. The apps are relatively basic. With Azmeh, users can post updates about the status of the hold-up at a checkpoint, using green to mark no traffic, orange for moderate and red for heavy, allowing other users to choose to divert to other, less clogged checkpoints. For now, the app tracks traffic at half a dozen checkpoints. Qalandiya also has users mark the level of traffic at the checkpoint, using green, red or yellow car icons. Users can also inform others if the checkpoint has been closed. Unlike Waze, the apps do not time the wait at a checkpoint or suggest a different route. Users must decide that on their own. Milena Ansari, a 21-year-old from east Jerusalem who studies at Birzeit University in the West Bank, drives through the Qalandiya checkpoint every day and uses the Azmeh app. "I check it every morning when I wake up and decide which road to take," she said. If Qalandiya is backed up, she said she takes a longer but less congested route through a smaller checkpoint. She said she sends reports in whenever she crosses. The apps themselves are hobbled by Israeli restrictions. According to interim peace agreements, Israeli authorities control cellular networks in the West Bank and they have not granted Palestinian telecommunication companies 3G access, meaning many data-heavy apps cannot be used on the road. Palestinians who choose to subscribe to an Israeli cellular provider can access 3G. Drivers using the apps connect through 2G, a previous generation of wireless technology that is sluggish. "The limitations of the Internet connectivity cause us problems," said Ahmed Zaytoun, the developer of Qalandiya. "When I worked on the application, I made sure that it wouldn't need a high speed (connection)." Palestinians have been using social media like Whatsapp and Facebook groups to share traffic updates but Zaytoun said users were posting unrelated content that made navigating the groups cumbersome. Mashhour Abu Daka, a former Palestinian minister of telecommunications and information technology who now works as a consultant, welcomed the apps but said they could only go so far in assisting Palestinian motorists in the face of Israeli restrictions. "It will be helpful. But it would be even more helpful if we didn't have checkpoints," he said. In this Tuesday, Nov. 10, 2015 photo, a Palestinian driver stands in traffic to enter Jerusalem at Qalandia checkpoint between Jerusalem and the West Bank city of Ramallah. A pair of new mobile apps hopes to help Palestinians navigate their way around snarled traffic at Israeli checkpoints in the West Bank, offering a high-tech response to an intractable problem: constant, burdensome and often seemingly random restrictions on movement.
