Networks of military alliances, wars, and international trade

2015-01-01

We investigate the role of networks of alliances in preventing (multilateral) interstate wars. We first show that, in the absence of international trade, no network of alliances is peaceful and stable. We then show that international trade induces peaceful and stable networks: Trade increases the density of alliances so that countries are less vulnerable to attack and also reduces countries’ incentives to attack an ally. We present historical data on wars and trade showing that the dramatic drop in interstate wars since 1950 is paralleled by a densification and stabilization of trading relationships and alliances. Based on the model we also examine some specific relationships, finding that countries with high levels of trade with their allies are less likely to be involved in wars with any other countries (including allies and nonallies), and that an increase in trade between two countries correlates with a lower chance that they will go to war with each other.

2017-12-01

To compare the outcomes among war veterans who pray/do not pray and who were not suffering mental disorders after the Bosnia-Herzegovina war (1992-95). The sample consists of 100 healthy Bosnian war veterans divided in two equal groups-one, a highly religious group inside which were individuals who perform five obligatory prayers every day, and another group of individuals who do not practice any daily prayer. We used Minnesota Multiphase Personal Inventory (MMPI), Profile Index of Emotions (PIE) and Life Style Questionnaire (LSQ). War veterans who prayed had significantly higher levels for: incorporation, self-protection, and for reactive formation; but significantly lower levels for regression, compensation, transfer, no-controlling, oppositional and aggressiveness than their peers who did not pray. Practicing religion (regular performing daily prayers) is associated with reduction of tendencies towards the tendency for risk, impulsiveness, and aggression. It is also associated with successful overcoming of emotional conflicts in war veterans who practiced religion than their peers who did not practice religion.

Standardizing psycho-medical torture during the War on Terror: Why it happened, how it happened, and why it didn't work.

PubMed

Balfe, Myles

2016-12-01

After 9/11/2001 the United States launched a global War on Terror. As part of this War, terrorism suspects were detained by the U.S. military and by the C.I.A. It is now widely recognized that the United States tortured a number of these detainees in the context of its 'enhanced interrogation' programme. This article examines how and why U.S. organizations developed standards that allowed healthcare professionals to become involved in torture; why the standards developed by U.S. security institutions failed to control the actions of enhanced interrogation personnel on the ground; and what the role of standards were in stopping the enhanced interrogation initiative. The article concludes by discussing the general lessons that the enhanced interrogation programme has for social science research on standards, namely that individuals can experience ambivalence when caught between competing organizational and professional standards and that it might be inherently difficult to successfully enact certain protocols when these relate to deviant or destructive acts.

Religious Moral Beliefs Inversely Related to Trauma Experiences Severity and Presented Posttraumatic Stress Disorder Among Bosnia and Herzegovina War Veterans.

PubMed

Hasanović, Mevludin; Pajević, Izet

2015-08-01

The aim of this study was to determine the correlation of the level of religious moral beliefs (RMB) with trauma experiences and posttraumatic stress disorder (PTSD) severity in war veterans of Bosnia and Herzegovina. The sample consists of 120 Bosnian war veterans divided into two equal groups-one with and one without PTSD. We used the Harvard Trauma Questionnaire and the RMB belief scale. We then correlated the severity of trauma experiences and PTSD symptoms with veterans' scores on the RMB scale. The score on the RMB scale was negatively correlated to severity of trauma experiences and PTSD symptoms (Pearson's r = -0.509, P = 0.004; Pearson's r = -0.325, P < 0.001, respectively). The RMB may have protective role in the mental health stability of severely traumatized war veterans.

Differential regulation of polarized synaptic vesicle trafficking and synapse stability in neural circuit rewiring in Caenorhabditis elegans

PubMed Central

Kurup, Naina; Kono, Karina

2017-01-01

Neural circuits are dynamic, with activity-dependent changes in synapse density and connectivity peaking during different phases of animal development. In C. elegans, young larvae form mature motor circuits through a dramatic switch in GABAergic neuron connectivity, by concomitant elimination of existing synapses and formation of new synapses that are maintained throughout adulthood. We have previously shown that an increase in microtubule dynamics during motor circuit rewiring facilitates new synapse formation. Here, we further investigate cellular control of circuit rewiring through the analysis of mutants obtained in a forward genetic screen. Using live imaging, we characterize novel mutations that alter cargo binding in the dynein motor complex and enhance anterograde synaptic vesicle movement during remodeling, providing in vivo evidence for the tug-of-war between kinesin and dynein in fast axonal transport. We also find that a casein kinase homolog, TTBK-3, inhibits stabilization of nascent synapses in their new locations, a previously unexplored facet of structural plasticity of synapses. Our study delineates temporally distinct signaling pathways that are required for effective neural circuit refinement. PMID:28636662

Characterization of chemical warfare G-agent hydrolysis products by surface-enhanced Raman spectroscopy

NASA Astrophysics Data System (ADS)

Inscore, Frank E.; Gift, Alan D.; Maksymiuk, Paul; Farquharson, Stuart

2004-12-01

The United States and its allies have been increasingly challenged by terrorism, and since the September 11, 2001 attacks and the war in Afghanistan and Iraq, homeland security has become a national priority. The simplicity in manufacturing chemical warfare agents, the relatively low cost, and previous deployment raises public concern that they may also be used by terrorists or rogue nations. We have been investigating the ability of surface-enhanced Raman spectroscopy (SERS) to detect extremely low concentrations (e.g. part-per-billion) of chemical agents, as might be found in poisoned water. Since trace quantities of nerve agents can be hydrolyzed in the presence of water, we have expanded our studies to include such degradation products. Our SERS-active medium consists of silver or gold nanoparticles incorporated into a sol-gel matrix, which is immobilized in a glass capillary. The choice of sol-gel precursor allows controlling hydrophobicity, while the porous silica network offers a unique environment for stabilizing the SERS-active metals. Here we present the use of these metal-doped sol-gels to selectively enhance the Raman signal of the hydrolyzed products of the G-series nerve agents.

Strategic planning and implementation of oral health care and disease prevention programmes after the 1990/91 Gulf war are discussed. The key concept was to develop access to care and disease prevention for all Kuwaiti children in government kindergarten/primary schools and to eliminate emphasis on extractions and restorations. Resources were restored to pre-war levels and then increased. Prevention programmes for 150 000 children were established. Prevention funds increased from 7% to 20% of the oral health budget. Prevention-based dentists increased from 9.7% to 28.0% of staff. Rising caries trends were stabilized or reduced by up to 36.8%. Percentage of caries-free primary dentition in children increased up to 37.6%, permanent dentition up to 27.0%. A dentistry school was established.

This study purports to analyze the conservative Arab monarchies' search for regional security in the Persian Gulf. It speculates on the GCC's future prospects as a vehicle of cooperation in the field of security. Threats to the member states of the GCC stem from the policies pursued by revolutionary Iran, Israel, the Soviet Union and its proxies, and a regime in Iraq. The proposition is developed that these sources of threat present an overwhelming challenge to the security and stability of GCC states.

The survival of 19th-century scientific optimism: the public discourse on science in Belgium in the aftermath of the Great War (ca. 1919-1930).

PubMed

Onghena, Sofie

2011-01-01

In historiography there is a tendency to see the Great War as marking the end of scientific optimism and the period that followed the war as a time of discord. Connecting to current (inter)national historiographical debate on the question of whether the First World War meant a disruption from the pre-war period or not, this article strives to prove that faith in scientific progress still prevailed in the 1920s. This is shown through the use of Belgium as a case study, which suggests that the generally adopted cultural pessimism in the post-war years did not apply to the public rhetoric of science in this country. Diverse actors -- scientists, industrialists, politicians, the public opinion, and the military staff -- declared a confidence in science, enhanced by wartime results. Furthermore, belief in science in Belgium was not affected by public outcry over the use of mustard gas, unlike in the former belligerent countries where the gas became an unpleasant reminder of how science was used during the war. Even German science with its industrial applications remained the norm after 1918. In fact, the faith in science exhibited during the pre-war years continued to exist, at least until the 1920s, despite anti-German sentiments being voiced by many sections of Belgian society in the immediate aftermath of the war.

Navigating the profits and pitfalls of governmental partnerships: the ICRC and intergovernmental relief, 1918-23.

PubMed

Lowe, Kimberly A

2015-10-01

The International Committee of the Red Cross (ICRC) is today a staunch proponent of the need for humanitarian organisations to remain independent of state interests, yet it deliberately solicited intergovernmental intervention in international relief after the First World War of 1914-18. This paper examines why an organisation committed to upholding the independence and impartiality of humanitarian action might still choose to partner with governmental bodies. It also highlights the historical beginnings of a linkage between international aid and geopolitics. To secure governmental funding for refugee relief during the 1920s, the ICRC argued that the humanitarian crises of the post-war years were a threat to the political and social stability of Europe. While this has become axiomatic, the interwar history of the ICRC demonstrates that the perceived connection between relief and geopolitical stability is historically constructed, and that it must continue to be asserted persuasively to be effective. © 2015 The Author(s).

The relationship between climate change and wars waged between nomadic and farming groups from the Western Han Dynasty to the Tang Dynasty period

2016-01-01

In ancient China, shifts in regional productivity of agriculture and animal husbandry, caused by climate change, either led to wars or peaceful relations between nomadic and farming groups. During the period spanning the Western Han Dynasty to the Tang Dynasty, 367 wars were waged between these groups. While 69 % of the wars were initiated by nomads, 62.4 % were won by the farming groups. On a centennial timescale, the battlegrounds were mostly in northern areas (at an average latitude of 38.92° N) during warm periods, moving southward (at an average latitude of 34.66° N) during cold periods. On a decadal timescale, warm climates corresponded to a high incidence of wars (a correlation coefficient of 0.293). While farming groups were inclined to initiate wars during dry and cold periods, their chances of achieving victory were reduced at such times. The main reasons for this are, first, that a warm climate provided a solid material foundation for nomadic and farming groups, contributing especially to enhanced productivity among the former. However, the overriding desire of nomadic groups to expand essential subsistence means led to wars. Second, during cold periods, farming groups moved to and settled in the south, while nomadic groups occupied the Central Plain. Thus, the locations of the battlefields also changed. While other factors also influenced these wars, climate change served as a backdrop, playing an indirect role in wars between these groups.

This study, using a longitudinal design, attempted to identify whether self-reported problems with violence were empirically associated with future violent behavior among Iraq and Afghanistan war veterans and whether and how collateral informant interviews enhanced the risk assessment process. Data were gathered from N = 300 participants (n = 150 dyads of Iraq and Afghanistan war veterans and family/friends). The veterans completed baseline and follow-up interviews 3 years later on average, and family/friends provided collateral data on dependent measures at follow-up. Analyses showed that aggression toward others at follow-up was associated with younger age, posttraumatic stress disorder, combat exposure, and a history of having witnessed parental violence growing up. Self-reported problems controlling violence at baseline had robust statistical power in predicting aggression toward others at follow-up. Collateral report enhanced detection of dependent variables: 20% of cases positive for violence toward others would have been missed relying only on self-report. The results identify a subset of Iraq and Afghanistan war veterans at higher risk for problematic postdeployment adjustment and indicate that the veterans' self-report of violence was useful in predicting future aggression. Underreporting of violence was not evidenced by most veterans but could be improved upon by obtaining collateral information.

The Iraq and Afghanistan wars are unlike earlier wars, and the women veterans who have served in them are unlike veterans of earlier wars. Now these veterans are presenting with distinctive general, genitourinary, reproductive, and behavioral health issues. When seeking health care after deployment, they may be accessing multiple health care providers across numerous sites, including the Veterans Health Administration and civilian facilities. Enhanced levels of understanding, respect, and concern for the many combat-related health challenges experienced by these veterans will help civilian nurses and other clinicians provide optimum care. Provision of health care to women veterans should be multidisciplinary and effectively coordinated among various health care providers and facilities to ensure that their post-deployment health and wellness needs are met. © 2018 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

A large proportion of Gulf War Veterans suffer from Gulf War Illness (GWI) - a devastating chronic disorder characterized by heterogeneous fatigue, pain and neuropsychological symptoms. In their recent Brain, Behavior and Immunity publication entitled "Curcumin Treatment Leads to Better Cognitive and Mood Function in a Model of Gulf War Illness with Enhanced Neurogenesis, and Alleviation of Inflammation and Mitochondrial Dysfunction in the Hippocampus", Kodali and colleagues (2018) report that the polyphenol curcumin improves cognition and mood in a rat model of GWI, potentially by increasing the expression of antioxidant genes and by reversing the effects of chronic combined acetylcholinesterase inhibitor exposure on neuroinflammation, mitochondrial respiration and hippocampal neurogenesis. This preclinical work is encouraging for our veterans who suffer chronically from GWI as well as for developing strategies to protect our troops during future deployments in similar environments.

In Ulan-Ude, in 1942, the mortality of children at the age from 0 to 15 years consisted 64% of total numbers of died persons. The main causes of children mortality during all the war were tuberculosis, pneumonia, toxic dyspepsia and diarrhea. In October 1942, the government adopted a special decree obligated Narcomzdrav of the USSR to re-establish the system of maternity and child care existed before the war. The focus was made on the district principle of functioning of women and children consultations and polyclinics and to take measures to enhance the children diet and food vitaminization. In Buryat-Mongolskaya ASSR, during the war period, no epidemics of infectious diseases were allowed. In this difficult period of life the first multifield children hospital and municipal infection hospital with children beds were established and functioned with success.

Many caregivers are encountering the issue of communicating with children and adolescents about current world events, specifically war and terrorism. As health care providers, it is important to raise awareness of how children may understand, interpret, and respond to related fears and concerns. Although honesty and reassurance are clearly the best approach, it is important to provide information that is developmentally appropriate. Providing education and guidance can reduce stress and enhance understanding of the chaotic events confronting our nation. It also provides a platform for communication and exploration should additional terrorist attacks or acts of war occur. It is important to examine how to approach children and adolescents to communicate with them about these sensitive issues.

Postwar City: Importance of Recycling Construction and Demolition Waste

2017-10-01

Wars and armed conflicts have heavy tolls on the built environment when they take place in cities. It is not only restricted to the actually fighting which destroys or damages buildings and infrastructure, but the damage and destruction inflicts its impacts way beyond the cessation of military actions. They can even have another impact through physical segregation of city quarters through walls and checkpoints that complicates, or even terminates, mobility of citizens, goods, and services in the post-war scenario. The accumulation of debris in the streets often impedes the processes of rescue, distribution of aid and services, and other forms of city life as well. Also, the amount of effort and energy needed to remove those residual materials to their final dumping sites divert a lot of urgently needed resources. In this paper, the components of construction and demolition waste found in post-war cities are to be discussed, relating each one to its origins and potential reuses. Then the issues related to the management of construction waste and demolition debris resulting from military actions are to be discussed. First, an outlook is to be given on the historical example of Berlin and how the city was severely damaged during World War II, and how the reconstruction of the city was aided in part by the reuse of demolition debris. Then two more recent examples will be given, the cities of Baghdad in Iraq, and Homs in Syria. In Baghdad, though major military actions have ceased but not all rubble is cleared out, some security structures in the form of concrete walls separate the cities into quarters and impede city life and lie around as poorly allocated resource needed for reconstruction. While in the case of Homs, and the wider Syrian context, major military operations are still raging, making more pressure on the resources needed for reconstruction. This recycling of demolition debris can bring economic and social stability through the conservation of resources, creation of jobs, and - eventually - the stabilization of the society in the midst of an atrocious war. Suggestions for relevant solutions will be given in both cities.

Intern support groups have been instituted in many residency programs to improve resident well-being. In this article, we discuss the themes that emerged in intern support group meetings in a family medicine program operating in a setting of war and political instability. We held support groups, led by a family physician and a psychologist, that met monthly. Participants were residents in the family medicine program at the American University of Beirut. These residents began their training days after the commencement of the 34-day war between Israel and Hizbollah in 2006. Themes and issues discussed by the residents were noted and are reported in this article. We found that despite the stressors of the political situation, our interns focused on the usual stress of internship, such as the difficulties of functioning as interns in other departments and dealing with the time demands of internship as their main sources of stress at the beginning of internship. The stresses associated with the war did not emerge in the group until later in the year. These included tension with patients and political confrontations with staff, as well as personal struggles with the lack of political stability and depressed mood. This paper serves to share our experience and highlight some areas of concern that residents experience when training in a country or region that is at war.

Dual-hormone stress reactivity predicts downstream war-zone stress-evoked PTSD.

The crucial role of the hypothalamic-pituitary-adrenal axis (HPA) in stress-related homeostasis suggests dysregulated HPA involvement in the pathogenesis of post-traumatic stress disorder (PTSD), yet most studies examining linkages between HPA axis measures and PTSD have yielded null findings. One untested explanation for this inconsistency is a failure to account for simultaneous adrenal and gonadal influence. Here we tested the singular and interactive effects of cortisol (C R ) and testosterone (T R ) reactivity as moderators of war-zone stress evoked PTSD emergence in the war-zone. U.S. soldiers (N=120) scheduled for deployment to Iraq completed pre-deployment measures of C R and T R stress reactivity to a CO 2 inhalation challenge. Once deployed, monthly assessments of exposure to traumatic war-zone stressors and PTSD symptoms were collected via a web-based assessment system. Cortisol hypo-reactivity potentiated the pathogenic impact of war-zone stressors only in soldiers for whom the CO 2 challenge did not elevate testosterone, suggesting that the dual hormone stress reactivity profile of blunted cortisol and testosterone may confer increased risk for PTSD emergence by potentiating the pathogenic effects of war-zone stressors. Findings underscore the utility of assessing both HPA and HPG stress reactivity when assessing PTSD vulnerability and may help inform efforts for enhanced soldier screening and inoculation to war-zone stressors.

Entering the New Millennium: Dilemmas in Arms Control

BROWN,JAMES

The end of the Cold War finds the international community no longer divided into two opposing blocks. The concerns that the community now faces are becoming more fluid, less focused, and, in many ways, much less predictable. Issues of religion, ethnicity, and nationalism; the possible proliferation of Weapons of Mass Destruction; and the diffusion of technology and information processing throughout the world community have greatly changed the international security landscape in the last decade. Although our challenges appear formidable, the United Nations, State Parties, nongovernmental organizations, and the arms control community are moving to address and lessen these concerns throughmore » both formal and informal efforts. Many of the multilateral agreements (e.g., NPT, BWC, CWC, CTBT, MTCR), as well as the bilateral efforts that are taking place between Washington and Moscow employ confidence-building and transparency measures. These measures along with on-site inspection and other verification procedures lessen suspicion and distrust and reduce uncertainty, thus enhancing stability, confidence, and cooperation.« less

Offshore wind farms as productive sites or ecological traps for gadoid fishes?--impact on growth, condition index and diet composition.

With the construction of wind farms all across the North Sea, numerous artificial reefs are created. These windmill artificial reefs (WARs) harbour high abundances of fish species which can be attracted from elsewhere or can be the result of extra production induced by these wind farms. To resolve the attraction-production debate in suddenly altered ecosystems (cf. wind farms), the possible consequences of attraction should be assessed; thereby bearing in mind that ecological traps may arise. In this paper we investigated whether the wind farms in the Belgian part of the North Sea act as ecological traps for pouting and Atlantic cod. Length-at-age, condition and diet composition of fish present at the windmill artificial reefs was compared to local and regional sandy areas. Fish data from the period 2009-2012 were evaluated. Mainly I- and II-group Atlantic cod were present around the WARs; while the 0- and I-group dominated for pouting. For Atlantic cod, no differences in length were observed between sites, indicating that fitness was comparable at the WARs and in sandy areas. No significant differences in condition index were observed for pouting. At the WARs, they were slightly larger and stomach fullness was enhanced compared to the surrounding sandy areas. Also diet differed considerably among the sites. The outcome of the proxies indicate that fitness of pouting was slightly enhanced compared to the surrounding sandy areas. No evidence was obtained supporting the hypothesis that the WARs act as an ecological trap for Atlantic cod and pouting. Copyright © 2013 Elsevier Ltd. All rights reserved.

Epilepsy is a neurological disease related to the occurrence of pathological oscillatory activity, but the basic physiological mechanisms of seizure remain to be understood. Our working hypothesis is that specific sensory processing circuits may present abnormally enhanced predisposition for coordinated firing in the dysfunctional brain. Such facilitated entrainment could share a similar mechanistic process as those expediting the propagation of epileptiform activity throughout the brain. To test this hypothesis, we employed the Wistar audiogenic rat (WAR) reflex animal model, which is characterized by having seizures triggered reliably by sound. Sound stimulation was modulated in amplitude to produce an auditory steady-state-evoked response (ASSR; -53.71Hz) that covers bottom-up and top-down processing in a time scale compatible with the dynamics of the epileptic condition. Data from inferior colliculus (IC) c-Fos immunohistochemistry and electrographic recordings were gathered for both the control Wistar group and WARs. Under 85-dB SLP auditory stimulation, compared to controls, the WARs presented higher number of Fos-positive cells (at IC and auditory temporal lobe) and a significant increase in ASSR-normalized energy. Similarly, the 110-dB SLP sound stimulation also statistically increased ASSR-normalized energy during ictal and post-ictal periods. However, at the transition from the physiological to pathological state (pre-ictal period), the WAR ASSR analysis demonstrated a decline in normalized energy and a significant increase in circular variance values compared to that of controls. These results indicate an enhanced coordinated firing state for WARs, except immediately before seizure onset (suggesting pre-ictal neuronal desynchronization with external sensory drive). These results suggest a competing myriad of interferences among different networks that after seizure onset converge to a massive oscillatory circuit. Copyright © 2017 IBRO.

How did Japanese rural dwellers become rapidly healthier in the two decades following World War II?: Examining the diverse policy interventions that improved the population's health.

PubMed

Yuasa, Motoyuki

2017-01-01

Objective　During the two decades following Japan's World War II surrender in 1945, tremendous improvement in the population's health was observed, particularly in infant mortality and life expectancy. How did Japanese rural dwellers achieve such remarkable health improvement during this relatively short time span while its economy remained heavily damaged following the war? While the efforts from government-driven public health strategies and programs are well known, relatively little is known about the contributions of policies in non-health sectors. Therefore, the main aim is to verify, using literature based sources, whether non-health sectors contributed to the betterment of the population's health in addition to the public health sector policies.Hypotheses　Synergistic efforts of diverse interventions from different policies and programs likely catalyzed the drastic health improvement observed in the Japanese population in the two decades after World War II. The Ministry of Health and Welfare, for example, implemented programs to provide health care services. These are thought to have contributed directly to reducing maternal and child mortality, as well as tuberculosis-related mortality. Additionally, the Ministry of Agriculture and Forestry carried out a nationwide livelihood improvement program to enhance individual and family lifestyles, improve indoor and outdoor environments, and strengthen social solidarity. The ministry also attempted to generate income stability for farmers through an agricultural improvement program to ensure allocation of household income to family health. The Ministry of Education also had an initiative to disseminate the concepts of democracy and rational thought to the Japanese population through a social education program. Through these efforts, superstition and pre-modern customs were reduced, and subsequently health awareness increased, leading to an improvement in the population's health.Conclusion　The public health policies implemented in Japan as well as the integration of various policies and programs addressing livelihoods, economics, and education greatly improved the population's health in a relatively short time. These non-health initiatives intersected with a wide range of health determinants. Verifying these hypotheses in detail would help develop effective measures for international aid to poverty-stricken regions. It also encourages alternative ways through which Japan could overcome its present-day challenges such as a rapidly aging population with limited access to national schemes for social security.

Violence and reproductive health preceding flight from war: accounts from Somali born women in Sweden.

PubMed

Byrskog, Ulrika; Olsson, Pia; Essén, Birgitta; Allvin, Marie Klingberg

2014-08-30

Political violence and war are push factors for migration and social determinants of health among migrants. Somali migration to Sweden has increased threefold since 2004, and now comprises refugees with more than 20 years of war experiences. Health is influenced by earlier life experiences with adverse sexual and reproductive health, violence, and mental distress being linked. Adverse pregnancy outcomes are reported among Somali born refugees in high-income countries. The aim of this study was to explore experiences and perceptions on war, violence, and reproductive health before migration among Somali born women in Sweden. Qualitative semi-structured individual interviews were conducted with 17 Somali born refugee women of fertile age living in Sweden. Thematic analysis was applied. Before migration, widespread war-related violence in the community had created fear, separation, and interruption in daily life in Somalia, and power based restrictions limited access to reproductive health services. The lack of justice and support for women exposed to non-partner sexual violence or intimate partner violence reinforced the risk of shame, stigmatization, and silence. Social networks, stoicism, and faith constituted survival strategies in the context of war. Several factors reinforced non-disclosure of violence exposure among the Somali born women before migration. Therefore, violence-related illness might be overlooked in the health care system. Survival strategies shaped by war contain resources for resilience and enhancement of well-being and sexual and reproductive health and rights in receiving countries after migration.

From world war to class war: the rebound of the rich.

Evans, Robert G

Incomes in Canada, as in many other countries, are becoming increasingly unequal. In North America this process has several notable features. First, after 40 years of stability, income has since 1980 been increasingly concentrated in the hands of the top 0.01% of earners. Second, this concentration correlates with an explosion in the relative earnings of corporate CEOs, a sort of "corporate kleptocracy." Third, the top earners have appropriated most of the productivity gains over this period. The resources and political influence of the super-rich underlie the growing prominence of the "elite" agenda: lower taxes, smaller government and privatization or shrinkage of social programs. The marketing of this agenda may explain much of the nonsense that contaminates health policy debates.

Emergence of social cohesion in a model society of greedy, mobile individuals

PubMed Central

Roca, Carlos P.; Helbing, Dirk

2011-01-01

Human wellbeing in modern societies relies on social cohesion, which can be characterized by high levels of cooperation and a large number of social ties. Both features, however, are frequently challenged by individual self-interest. In fact, the stability of social and economic systems can suddenly break down as the recent financial crisis and outbreaks of civil wars illustrate. To understand the conditions for the emergence and robustness of social cohesion, we simulate the creation of public goods among mobile agents, assuming that behavioral changes are determined by individual satisfaction. Specifically, we study a generalized win-stay-lose-shift learning model, which is only based on previous experience and rules out greenbeard effects that would allow individuals to guess future gains. The most noteworthy aspect of this model is that it promotes cooperation in social dilemma situations despite very low information requirements and without assuming imitation, a shadow of the future, reputation effects, signaling, or punishment. We find that moderate greediness favors social cohesionby a coevolution between cooperation and spatial organization, additionally showing that those cooperation-enforcing levels of greediness can be evolutionarily selected. However, a maladaptive trend of increasing greediness, although enhancing individuals’ returns in the beginning, eventually causes cooperation and social relationships to fall apart. Our model is, therefore, expected to shed light on the long-standing problem of the emergence and stability of cooperative behavior. PMID:21709245

Why Did U.S. Healthcare Professionals Become Involved in Torture During the War on Terror?

PubMed

Balfe, Myles

2016-09-01

This article examines why U.S. healthcare professionals became involved in "enhanced interrogation," or torture, during the War on Terror. A number of factors are identified including a desire on the part of these professionals to defend their country and fellow citizens from future attack; having their activities approved and authorized by legitimate command structures; financial incentives; and wanting to prevent serious harm from occurring to prisoners/detainees. The factors outlined here suggest that psychosocial factors can influence health professionals' ethical decision-making.

The relationship between strategic offensive capabilities (reflected in the SIOP) and emerging strategic defensive capabilities (reflected by SDI) is not being adequately addressed. A summary of the existing nuclear war planning process is provided, and an analagous defensive process is postulated. Parallels and differences between the two processes are discussed. Potential areas for information exchange and cooperation are identified to enhance deterrence and improve war fighting potential. Operational, technical and political issues requiring resolution are raised and recommendations to resolve these issues are made.

Cyber Deterrence and Stability

DOE Office of Scientific and Technical Information (OSTI.GOV)

Goychayev, Rustam; Carr, Geoffrey A.; Weise, Rachel A.

Throughout the 20th and early 21st centuries, deterrence and arms control have been cornerstones of strategic stability between the superpowers. However, the weaponization of the cyber realm by State actors and the multipolar nature of cyber conflict now undermines that stability. Strategic stability is the state in which nations believe that if they act aggressively to undermine U.S. national interests and the post-World War II liberal democratic order, the consequences will outweigh the benefits. The sense of lawlessness and lack of consequences in the cyber realm embolden States to be more aggressive in taking actions that undermine stability. Accordingly, thismore » paper examines 1) the role of deterrence and arms control in securing cyber stability, and 2) the limitations and challenges associated with these traditional national security paradigms as applied to this emerging threat domain. This paper demonstrates that many 20th-century deterrence and arms control concepts are not particularly applicable in the cyber realm. However, they are not entirely irrelevant. The United States can distill lessons learned from this rich deterrence and arms control experience to develop and deploy a strategy to advance cyber stability.« less

Some facets of the life of Hans Bethe after World War II are presented to illustrate how Paul Forman's works, and in particular his various theses—on mathematics and physics in Wilhelmine and Weimar Germany, on physics in the immediate post-World War II period, and on postmodernity—have influenced my biography of Bethe. Some aspects of the history of post-World War II quantum field theory, of solid state/condensed matter physics, and of the development of neoliberalism—the commitment to the belief that the market knows best, to free trade, to enhanced privatization, and to a drastic reduction of the government's role in regulating the economy—are reviewed in order to make some observations regarding certain "top-down" views in solid state physics in postmodernity, the economic and cultural condition of many Western societies since the 1980s, the decade in which many historians assume modernity to have ended.

The early days of optical coatings

NASA Astrophysics Data System (ADS)

Macleod, Angus

1999-12-01

The history of optical coatings is a long one with many observations and publications but little industrial activity until a period of explosive growth began in the 1940s. The trigger was World War II and the need on all sides for improved optical instruments ranging from binoculars to periscopes and bombsights, but it is certain that the growth would have occurred, perhaps a year or two later, even without the war. After the war the growth continued, partly because of military needs, but much more because of other factors such as the continuing growth in general optics, the enormous expansion of the chemical industry and its need for infrared and visible analytical tools, the need for narrowband contrast enhancing filters in astronomy, and then, very significantly, the laser. Nowadays, optical coatings are indispensible features of virtually all optical systems.

Using art as a self-regulating tool in a war situation: a model for social workers.

PubMed

Huss, Ephrat; Sarid, Orly; Cwikel, Julie

2010-08-01

War poses a challenge for social workers, adding exposure to direct risk of personal harm to the general stress of social work practice. Artworks are frequently used in health care settings with people in high distress. This study had three goals: (1) to characterize the stressors of social workers living in a war zone, (2) to teach social workers in crisis situations to identify stress and resilience factors in their artworks, and (3) to develop a general self-care model for arts intervention for professionals in these situations. Common stressors experienced by participants were anxiety and fear as a result of bombs, sirens, worry over loved ones, and overexposure to media. These were layered onto professional stressors, including constant work communication on cell phones during war and dilemmas related to work-family conflicts. Allowing social workers to name and identity the sources of their stress and then change their artwork to enhance resilience helped them to gain a sense of control over diffuse sources of anxiety. The authors propose this method as an effective intervention model with social workers in high-stress situations.

[Epidemiological situation of infectious diseases in Lvov and Cracow during and after World War I (until the year 1922)].

PubMed

Berner, Włodzimierz

2009-01-01

In Lvov and Cracow at the times of World War I, the infectious diseases such as tuberculosis followed by typhus fever, typhoid fever, dysentery, as well as scarlet fever, diphtheria, measles, whooping cough, smallpox, cholera and venereal diseases (particularly syphilis) posed one of the most significant and dangerous problems for inhabitants. Their increased prevalence was the result of deteriorating sanitary and living conditions of the city population. The spread of epidemic infectious diseases was enhanced by marching troops, migration of civilians and war prisoners, return of large groups of displaced people and demobilized soldiers after regaining independence in November 1918. Additionally, unfavorable epidemiological situation in Lvov deteriorated at the time of the war with Ukrainians (November 1918-April 1919) and Bolsheviks (July-August 1920). The control of infectious diseases was in the hands of regional local physicians who referred patients to hospitals, isolated homes, bath and disinfection institutions, and conducted vaccinations against smallpox. A decrease in infectious diseases prevalence and deaths to the prewar levels occurred in 1922.

Periodic climate cooling enhanced natural disasters and wars in China during AD 10–1900

Recent studies have linked climatic and social instabilities in ancient China; the underlying causal mechanisms have, however, often not been quantitatively assessed. Here, using historical records and palaeoclimatic reconstructions during AD 10–1900, we demonstrate that war frequency, price of rice, locust plague, drought frequency, flood frequency and temperature in China show two predominant periodic bands around 160 and 320 years where they interact significantly with each other. Temperature cooling shows direct positive association with the frequency of external aggression war to the Chinese dynasties mostly from the northern pastoral nomadic societies, and indirect positive association with the frequency of internal war within the Chinese dynasties through drought and locust plagues. The collapses of the agricultural dynasties of the Han, Tang, Song and Ming are more closely associated with low temperature. Our study suggests that food production during the last two millennia has been more unstable during cooler periods, resulting in more social conflicts owing to rebellions within the dynasties or/and southward aggressions from northern pastoral nomadic societies in ancient China.

Accumulating evidence from different animal models has contributed to the understanding of the bidirectional comorbidity associations between the epileptic condition and behavioral abnormalities. A strain of animals inbred to enhance seizure predisposition to high-intensity sound stimulation, the Wistar audiogenic rat (WAR), underwent several behavioral tests: forced swim test (FST), open-field test (OFT), sucrose preference test (SPT), elevated plus maze (EPM), social preference (SP), marble burying test (MBT), inhibitory avoidance (IAT), and two-way active avoidance (TWAA). The choice of tests aimed to investigate the correlation between underlying circuits believed to be participating in both WAR's innate susceptibility to sound-triggered seizures and the neurobiological substrates associated with test performance. Comparing WAR with its Wistar counterpart (i.e., resistant to audiogenic seizures) showed that WARs present behavioral despair traits (e.g., increased FST immobility) but no evidence of anhedonic behavior (e.g., increased sucrose consumption in SPT) or social impairment (e.g., no difference regarding juvenile exploration in SP). In addition, tests suggested that WARs are unable to properly evaluate degrees of aversiveness (e.g., performance on OFT, EPM, MBT, IAT, and TWAA). The particularities of the WAR model opens new venues to further untangle the neurobiology underlying the co-morbidity of behavioral disorders and epilepsy.

Financial Well-Being and Post-Deployment Adjustment among Iraq and Afghanistan War Veterans

Elbogen, Eric B.; Johnson, CAPT Sally C.; Wagner, H. Ryan; Newton, Virginia M.; Beckham, Jean C.

2012-01-01

Research has yet to examine the relationship between financial well-being and community reintegration of veterans. To address this, we analyzed data from n=1,388 Iraq and Afghanistan War Era Veterans who completed a national survey on post-deployment adjustment. The results indicated that probable major depressive disorder, posttraumatic stress disorder, and traumatic brain injury were associated with financial difficulties. However, regardless of diagnosis, veterans who reported having money to cover basic needs were significantly less likely to have post-deployment adjustment problems such as criminal arrest, homelessness, substance abuse, suicidal behavior, and aggression. Statistical analyses also indicated that poor money management (e.g. incurring significant debt or writing bad checks) was related to maladjustment, even among veterans at higher income levels. Given these findings, efforts aimed at enhancing financial literacy and promoting meaningful employment may have promise to enhance outcomes and improve quality of life among returning veterans.

Borrowed buildings: Canada's temporary hospitals during World War I.

Adams, A

1999-01-01

This article explores the alterations and additions made to houses, colleges, and larger public buildings in their temporary use as convalescent homes for wounded Canadian soldiers during World War I. These ''borrowed buildings'' anticipated and emphasized three important characteristics of subsequent hospital architecture by suggesting that domestic environments enhanced healing, that hospitals should be accessible, and that patients should be segregated according to social status and disease. The broader implications of the study are that temporarily appropriated spaces contribute to the definition of many institutions and often act as arenas of resistance to established practices.

The Libyan civil conflict: selected case series of orthopaedic trauma managed in Malta in 2014.

The purpose of this series of cases was to analyse our management of orthopaedic trauma casualties in the Libyan civil war crisis in the European summer of 2014. We looked at both damage control orthopaedics and for case variety of war trauma at a civilian hospital. Due to our geographical proximity to Libya, Malta was the closest European tertiary referral centre. Having only one Level 1 trauma care hospital in our country, our Trauma and Orthopaedics department played a pivotal role in the management of Libyan battlefield injuries. Our aims were to assess acute outcomes and short term mortality of surgery within the perspective of a damage control orthopaedic strategy whereby aggressive wound management, early fixation using relative stability principles, antibiotic cover with adequate soft tissue cover are paramount. We also aim to describe the variety of war injuries we came across, with a goal for future improvement in regards to service providing. Prospective collection of six interesting cases with severe limb and spinal injuries sustained in Libya during the Libyan civil war between June and November 2014. We applied current trends in the treatment of war injuries, specifically in damage control orthopaedic strategy and converting to definitive treatment where permissible. The majority of our cases were classified as most severe (Type IIIB/C) according to the Gustilo-Anderson classification of open fractures. The injuries treated reflected the type of standard and improved weaponry available in modern warfare affecting both militants and civilians alike with increasing severity and extent of damage. Due to this fact, multidisciplinary team approach to patient centred care was utilised with an ultimate aim of swift recovery and early mobilisation. It also highlighted the difficulties and complex issues required on a hospital management level as a neighbouring country to war zone countries in transforming care of civil trauma to military trauma.

The role of the sand in chemical warfare agent exposure among Persian Gulf War veterans: Al Eskan disease and "dirty dust".

PubMed

Korényi-Both, A L; Svéd, L; Korényi-Both, G E; Juncer, D J; Korényi-Both, A L; Székely, A

2000-05-01

The purpose of this paper is to inquire into the relationship between Al Eskan disease and the probable exposure to chemical warfare agents by Persian Gulf War veterans. Al Eskan disease, first reported in 1991, compromises the body's immunological defense and is a result of the pathogenic properties of the extremely fine, dusty sand located in the central and eastern region of the Arabian peninsula. The disease manifests with localized expression of multisystem disorder. Signs and symptoms of Al Eskan disease have been termed by the news media "Persian Gulf syndrome." The dust becomes a warfare agent when toxic chemicals are microimpregnated into inert particles. The "dirty dust" concept, that the toxicity of an agent could be enhanced by absorption into inactive particles, dates from World War I. A growing body of evidence shows that coalition forces have encountered Iraqi chemical warfare in the theater of operation/Persian Gulf War to a much greater extent than early U.S. Department of Defense information had indicated. Veterans of that war were exposed to chemical warfare agents in the form of direct (deliberate) attacks by chemical weapons, such as missiles and mines, and indirect (accidental) contamination from demolished munition production plants and storage areas, or otherwise. We conclude that the microimpregnated sand particles in the theater of operation/Persian Gulf War depleted the immune system and simultaneously acted as vehicles for low-intensity exposure to chemical warfare agents and had a modifying-intensifying effect on the toxicity of exposed individuals. We recommend recognition of a new term, "dirty sand," as a subcategory of dirty dust/dusty chemical warfare agents. Our ongoing research efforts to investigate the health impact of chemical warfare agent exposure among Persian Gulf War veterans suggest that Al Eskan disease is a plausible and preeminent explanation for the preponderance of Persian Gulf War illnesses.

Recording memories of World War II is an intervention that can humanize geriatric care in addition to the historical significance provided. Participants in this oral history project described memories of World War II and expressed themes of patriotism, loss, tense moments, makeshift living, self-sufficiency, and uncertain journey. Their ethnic roots were primarily Scandinavian, Dutch, German, and English. The nursing home participants were slightly older than the community participants (mean ages: 85.5 and 82.4 years, respectively). More women (58%) than men (42%) participated, and 35% of the participants were veterans (eight men one woman). Nursing home and community residents participated in this project, and reciprocal benefits were experienced by participants and listeners alike. Memories of World War II provide a meaningful topic for oral histories. Listening and valuing oral history supports, involves, and validates elders. Oral history has reciprocal benefits that can create a culture to enhance a therapeutic environment.

Around 27,000 people were killed in the province of Asturias during the Spanish Civil War, with several thousands killed after the war ended. There are currently over 2,000 known mass burial locations throughout Spain, but many more are unknown. Geophysics is a useful tool employed to help in the active attempts to document and improve knowledge about victims from this conflict. This paper details a non-invasive study of the Cementerio de El Salvador, in the city of Oviedo, Northern Spain. Part of the cemetery contains a known mass burial with approximately 1,300 individuals from the Spanish Civil War and post-war repression eras. Multi-frequency near-surface geophysical techniques were undertaken, after permission, to enhance knowledge about which, if any, techniques should be used to detect, delineate and analyse such mass graves. Multi-frequency (250MHz and 500MHz) ground-penetrating radar surveys were acquired together with 2D and 3D Electrical Resistivity Tomography datasets. The results have established the limits of the mass grave and improve the knowledge of the internal mass grave structure.

More a plowshare than a sword: the legacy of US Cold War agricultural diplomacy.

PubMed

McGlade, Jacqueline

2009-01-01

Recently, agriculture has assumed an elevated role in world diplomacy due to pressing issues like international poverty relief, changing environmental conditions, farm trade imbalances, rising food prices, and the diversion of crops into bio-fuel production. Consequently, agricultural interests and production have become increasingly entwined with the politics of national protectionism and identity, domestic security, and the preservation of trading advantage in developed and developing countries alike. This study examines the current impasse in world agricultural negotiations as an outgrowth of US foreign aid and trade policymaking as it evolved during the Cold War. In particular, it chronicles the historic shift in US foreign policy away from "give-away" food aid and surplus sales and toward the championing of global agricultural redevelopment under such programs as the Marshall Plan and PL 480, the Food for Peace program. As more a plowshare than a sword, the American Cold War push for worldwide agricultural modernization led many countries to experience new levels of food self-efficiency and export capabilities. Along with production parity, however, has come escalating levels of trade competition and national protectionism, which challenges again the achievement of world agricultural stability and prosperity.

Thermonuclear peace, the tightrope of deterrence

Uscher, A.R.

This policy analysis focuses on the actions and approaches that will best reduce the chances of nuclear war in a MAD world, where mutual terror and mutual dependence will define our bipolar environment for the foreseeable future. The general approach to this broad and complex issue can be summarized as follows: since plans for conducting and preventing nuclear war are likely to be self-fulfilling prophecies, the US should strive for rational declaratory and deployment policies that reduce the chance of nuclear conflict while maintaining our national-security interests. Stability, probably the single most-important and unifying theme in nuclear deterrence, is visualizedmore » as a set of incentive structures that create no perceived advantages in escalating at any point along a hypothetical-force continuum. The key element in establishing and maintaining superpower stability is the inability to achieve adequate damage limitation through a preemptive first strike. The power and number of nuclear weapons compared to the fragility and limited number of priority targets seriously challenge the utility of most defensive measures. Successfully walking the tightrope of deterrence will require careful balancing of legitimate and competing values. This is a difficult task, but with a clear and realistic vision of the future, it is a feasible one.« less

This study evaluates the mental health of Japan Self-Defense Force (JSDF) members of the peacekeeping contingent in the Golan Heights before and since the Second Gulf War between 1998 and 2003. Before the war, the General Health Questionnaire 30 (GHQ30) scores during and after duty tended to be lower than those before duty; all scores were lower than those of adult Japanese men in general. After the war, GHQ30 scores did not significantly change between before, during, and after duty. Manifest Anxiety Scale (MAS) scores were not significantly different between groups. Stressors identified included problems with foreign language and familial matters at home. Post war stressors included work content and relationships with collaborating foreign army units. These findings suggest that the mental health of contingent members remained stable, with some variation in mental health conditions influenced by the situation in the Middle East. This study suggests that the stable mental condition of JSDF personnel during their deployment in the absence of combat, and that this could be enhanced by education about mental health issues and by providing counseling support to their families.

In this article, we discuss the successful implementation of an adapted evidence-based parenting intervention for families affected by two decades of war in Northern Uganda. The adaptation and adoption of such interventions to support mental health and family functioning is widely endorsed by prevention scientists and considered a priority in global mental health. The preparation and early adoption phases of engaging with a highly vulnerable community affected by war trauma are documented in this paper along with a discussion of the steps taken to adapt a parenting intervention for cultural and contextual fit. This study is a component of an overall program of research aimed at reducing the long-term negative effects of war on parenting practices and childhood outcomes, which have considerable implications for preventing mental, neurological, and substance-use disorders. The processes described here cover a 4-year period culminating in the implementation of the nine-session Enhancing Family Connection intervention piloted with a group of 14 mothers. The lessons in cultural adaptation have been valuable and the feasibility results promising for further testing the intervention. © 2015 Family Process Institute.

Military medical advances resulting from the conflict in Korea, Part I: Systems advances that enhanced patient survival.

Baker, Michael S

2012-04-01

The Korean War started several years after the World War II had ended and no recognition of the threat or preparation was made for this possibility. The military and its medical service had been downsized after World War II and had to quickly ramp up to meet the surprise attack. The war provided the laboratory for trials and experimentation with the new technological developments of the era. The Korean conflict led to numerous advances in medical systems and patient care. The Mobile Army Surgical Hospital came of age, and was instrumental in saving many lives. Helicopters saw their first regular use as flying ambulances to take the injured to definitive care in a timely fashion. The national blood banking program was rapidly geared up and new techniques such as plastic bags for collection and delivery resulted. Body armor was developed that would allow mobility while offering protection and was widely used for the first time. Each of these systems improvements saved the lives of soldiers in combat and were soon to be used in the civilian sector to save and improve lives around the world.

Plastic Surgery Challenges in War Wounded I: Flap-Based Extremity Reconstruction

PubMed Central

Sabino, Jennifer M.; Slater, Julia; Valerio, Ian L.

2016-01-01

Scope and Significance: Reconstruction of traumatic injuries requiring tissue transfer begins with aggressive resuscitation and stabilization. Systematic advances in acute casualty care at the point of injury have improved survival and allowed for increasingly complex treatment before definitive reconstruction at tertiary medical facilities outside the combat zone. As a result, the complexity of the limb salvage algorithm has increased over 14 years of combat activities in Iraq and Afghanistan. Problem: Severe poly-extremity trauma in combat casualties has led to a large number of extremity salvage cases. Advanced reconstructive techniques coupled with regenerative medicine applications have played a critical role in the restoration, recovery, and rehabilitation of functional limb salvage. Translational Relevance: The past 14 years of war trauma have increased our understanding of tissue transfer for extremity reconstruction in the treatment of combat casualties. Injury patterns, flap choice, and reconstruction timing are critical variables to consider for optimal outcomes. Clinical Relevance: Subacute reconstruction with specifically chosen flap tissue and donor site location based on individual injuries result in successful tissue transfer, even in critically injured patients. These considerations can be combined with regenerative therapies to optimize massive wound coverage and limb salvage form and function in previously active patients. Summary: Traditional soft tissue reconstruction is integral in the treatment of war extremity trauma. Pedicle and free flaps are a critically important part of the reconstructive ladder for salvaging extreme extremity injuries that are seen as a result of the current practice of war. PMID:27679751

The enhanced stability and biodegradation of dispersed crude oil droplets by Xanthan Gum as an additive of chemical dispersant.

PubMed

Wang, Aiqin; Li, Yiming; Yang, Xiaolong; Bao, Mutai; Cheng, Hua

2017-05-15

It is necessary for chemical dispersant to disperse oil effectively and maintain the stability of oil droplets. In this work, Xanthan Gum (XG) was used as an environmentally friendly additive in oil dispersant formulation to enhance the stability and biodegradation of dispersed crude oil droplets. When XG was used together with chemical dispersant 9500A, the dispersion effectiveness of crude oil in artificial sea water (ASW) and the oil droplet stability were both greatly enhanced. In the presence of XG, lower concentration of 9500A was needed to achieve the effective dispersion and stabilization. In addition to the enhancement of dispersion and stabilization, it was found that the biodegradation rate of crude oil by bacteria was dramatically enhanced when a mixture of 9500A and XG was used as a dispersant. Because of the low environmental impact of XG, this would be a potential way to formulate the dispersant with lower toxicity. Copyright © 2017 Elsevier Ltd. All rights reserved.

World War II, post-war reconstruction and British women chemists.

PubMed

Horrocks, Sally

2011-07-01

This paper draws on evidence from a range of sources to consider the extent to which World War II served as a turning point in the employment opportunities open to women chemists in Britain. It argues that wartime conditions expanded women's access to some areas of employment, but that these opportunities represented, in many ways, an expansion of existing openings rather than wholly new ones, and not all of them proved permanent. Instead, women chemists benefited more permanently from increased state expenditure on higher education and on research and development after the war. This enabled some women to remain in what had originally been temporary wartime posts and others to secure employment in wholly new positions. Women were most successful in securing positions created by the expansion of state welfare and support for agriculture, but also found new employment opportunities as a result of the heavy investment in weapons development that accelerated with the advent of the Cold War. In higher education, an initial expansion of openings was not sustained, and the proportion of women in university chemistry departments actually fell during the second half of the 1950s. Industry presents a rather ambiguous picture, with many firms continuing to refuse to employ women chemists, whereas elsewhere they enjoyed enhanced opportunities and better salaries than those offered before the war. This did not mean, however, that women chemists received equal treatment to their male colleagues, and, despite the changes, they remained concentrated in subordinate positions and were expected to concentrate on routine work. Prospects in the 1950s were certainly better than they had been during the 1930s, but they remained strongly gendered.

Defying the activity-stability trade-off in enzymes: taking advantage of entropy to enhance activity and thermostability.

PubMed

Siddiqui, Khawar Sohail

2017-05-01

The biotechnological applications of enzymes are limited due to the activity-stability trade-off, which implies that an increase in activity is accompanied by a concomitant decrease in protein stability. This premise is based on thermally adapted homologous enzymes where cold-adapted enzymes show high intrinsic activity linked to enhanced thermolability. In contrast, thermophilic enzymes show low activity around ambient temperatures. Nevertheless, genetically and chemically modified enzymes are beginning to show that the activity-stability trade-off can be overcome. In this review, the origin of the activity-stability trade-off, the thermodynamic basis for enhanced activity and stability, and various approaches for escaping the activity-stability trade-off are discussed. The role of entropy in enhancing both the activity and the stability of enzymes is highlighted with a special emphasis placed on the involvement of solvent water molecules. This review is concluded with suggestions for further research, which underscores the implications of these findings in the context of productivity curves, the Daniel-Danson equilibrium model, catalytic antibodies, and life on cold planets.

Bridging psychological barriers between the child and the father after his returning from the war: Could group art therapy help?

Mandić-Gajić, Gordana

2016-07-01

War veterans with chronic post-traumatic stress disorder (PTSD) have poorer family and parenting functioning, but little research has focused on these impairments. This paper presented how the series of drawings and the group art therapy process enhanced bridging the psychological barriers of a 33-year-old male PTSD war veteran to engagement with the child. After two years of deployment he returned home and suffered mostly from PTSD numbness and avoidance symptoms. The veteran had the family readjustment difficulties and felt guilty for being detached from his 3-year-old son. He under-went integrative treatment in the Day Unit Program. The drawings series were made by free associations. Clinical observations and group discussions were recorded in the group art therapy protocols. The presented patient got gratifications and support from the group members for his illustration of popular cartoon heroes, and decided to draw Mickey Mouse at home. On the next session he shared his satisfaction for bridging the gap between him and his son, having done the same drawings with his son at home. Beck's depression inventory (BDI) was used for self-rating of depression and a reduction of BDI score from 18 to 6 during the treatment course was recorded. Series of drawings illustrated shift from war related past toward current family life of the war veteran. Group art therapy gave him gratification and support with hope and a sense of belonging, thus facilitated his parenting readjustment.

Aid in a city at war: the case of Mogadishu, Somalia.

PubMed

Grünewald, François

2012-07-01

Mogadishu, the capital of Somalia, has been central to life, war, and peace in the country for almost two decades. Its urban characteristics, though, have been put to one side for the most part. In recent years, Mogadishu-related issues have been merged mostly into a global agenda for South and Central Somalia, resulting in the technical and coordination approaches employed in the city largely being reproductions of solutions utilised in refugee camps and rural areas. Unfortunately, urban problems require urban solutions. The aid system is just starting to discover how specific aid in cities at war should be, both from an organisational and a technical standpoint. The enhancement of aid practices in an urban setting implies, among other things, a more strategic approach to the specific spatial characteristics of the city, a more fine-tuned analysis of the technical requirements of the urban service delivery systems, and a better understanding of the role of urban institutions. © 2012 The Author(s).

100 million refugees. The world stabilizes through population stability.

PubMed

Sakaiya, T

1993-09-01

Global change has come about due to shifts in the business cycle, a new undeveloped paradigm to replace the Cold War, and a stabilization of expansion and development of modern industrial society. Japan has been transfixed with its own internal domestic affairs, but will feel the consequences of the Industrial Age nearing its end. Industrialization had relied on unlimited resources from the natural environment and the belief that a free-market economy would automatically lead to orderliness and a state of economic equilibrium. Population control has been an issue that has slid over the years as a priority status. In 1800, the population in developed countries was 4 times the population in developing countries; the reverse is becoming true. Mass migration was an unusual phenomena and not the problem it is today. There is a gap between population and productive capacity. Developed countries believed in humanitarian aid for refugees and impoverished peoples, but the numbers were unanticipated. There is no shame for war or civil unrest to drive boat people and hugh numbers to another country. The notion of nation state has changed. The boat people from Cuba were a beginning example of how governments were unconcerned about the loss of population. Afghanistan in 1979 was another example of refugees fleeing civil war. Iraq bombed the Kurds until there was no choice but to leave. Turkey was required to use troops to drive the Kurds back into Iraq. To increase aid indefinitely, or to send out more refugees than it takes in, or to use military forces to kill the invading refugees are not acceptable. An international framework with consensus from developed and developing countries is needed for dealing with mass migrations. Conventions adopted would have to be recognized as in each countries self-interest; disregard of the regulations would have to reflect significant disadvantages to a nation. Several issues are discussed as key in such a global framework: assuring productivity for all by absorbing some refugees, and developing new training programs for the private sector at home, and assuring development aid (technology, capital, markets). A self perpetuating cycle of growth and expansion must be set in motion. Infrastructure development must be replaced with stable employment in the home country.

History of internal fixation with plates (part 2): new developments after World War II; compressing plates and locked plates.

PubMed

Hernigou, Philippe; Pariat, Jacques

2017-07-01

The first techniques of operative fracture with plates were developed in the 19th century. In fact, at the beginning these methods consisted of an open reduction of the fracture usually followed by a very unstable fixation. As a consequence, the fracture had to be opened with a real risk of (sometimes lethal) infection, and due to unstable fixation, protection with a cast was often necessary. During the period between World Wars I and II, plates for fracture fixation developed with great variety. It became increasingly recognised that, because a fracture of a long bone normally heals with minimal resorption at the bone ends, this may result in slight shortening and collapse, so a very rigid plate might prevent such collapse. However, as a consequence, delayed healing was observed unless the patient was lucky enough to have the plate break. One way of dealing with this was to use a slotted plate in which the screws could move axially, but the really important advance was recognition of the role of compression. After the first description of compression by Danis with a "coapteur", Bagby and Müller with the AO improved the technique of compression. The classic dynamic compression plates from the 1970s were the key to a very rigid fixation, leading to primary bone healing. Nevertheless, the use of strong plates resulted in delayed union and the osteoporosis, cancellous bone, comminution, and/or pathological bone resulted in some failures due to insufficient stability. Finally, new devices represented by locking plates increased the stability, contributing to the principles of a more biological osteosynthesis while giving enough stability to allow immediate full weight bearing in some patients.

Enhancing the performance of tungsten doped InZnO thin film transistors via sequential ambient annealing

This study suggests a sequential ambient annealing process as an excellent post-treatment method to enhance the device performance and stability of W (tungsten) doped InZnO thin film transistors (WIZO-TFTs). Sequential ambient annealing at 250 °C significantly enhanced the device performance and stability of WIZO-TFTs, compared with other post-treatment methods, such as air ambient annealing and vacuum ambient annealing at 250 °C. To understand the enhanced device performance and stability of WIZO-TFT with sequential ambient annealing, we investigate the correlations between device performance and stability and electronic structures, such as band alignment, a feature of the conduction band, and band edge states below the conduction band. The enhanced performance of WIZO-TFTs with sequential ambient annealing is related to the modification of the electronic structure. In addition, the dominant mechanism responsible for the enhanced device performance and stability of WIZO-TFTs is considered to be a change in the shallow-level and deep-level band edge states below the conduction band.

Part 1 examines the country's evolution into modern Iraq, explaining why problems that have recurred throughout Iraqi history have bedeviled all recent Iraqi governments and created tension between ''Iraq the nation'' and ''Iraq the state.'' Part 2 discusses the Arab Ba'th Socialist party, which has dominated Iraqi political life since 1968. The author neither condemns nor praises this controversial party and its current leader, President Saddam Husain, but seeks to explain why they have adopted the positions and taken the actions that have characterized their rule. Part 3 analyzes the war between Iraq and Iran, its causes, and the decisions Iraq has made in light of its goals and its assumptions about Iran. The author finds that this is not simply ''a war over borders'' but a deeper conflict between Islamic conservatism and Arab nationalism. Looking beyond the war, the final chapter assesses Iraq's potential importance in the Middle East and to the world economy. 8 figs.« less

The troublesome birth of hydrodynamic stability theory: Sommerfeld and the turbulence problem

NASA Astrophysics Data System (ADS)

Eckert, M.

2010-07-01

More than a hundred years ago William McFadden Orr and Arnold Sommerfeld conceived an approach to account for the transition from laminar to turbulent flow in terms of hydrodynamic stability theory. But the “turbulence problem”, as this challenge became notoriously famous, could not be solved by this method. By 1920, it was widely recognized as an outstanding riddle. Although famous theoretical physicists like Werner Heisenberg dedicated a considerable effort to this problem, the “Orr-Sommerfeld method” has never found the attention of historians of science. This article describes its early perception and development in Germany, and how the “turbulence problem” reached center stage after the First World war as a major challenge for theorists with different perspectives.

SIOP for Perestroika. Research report

1990-04-01

The pursuit of greater stability through arms reductions is an important component of perestroika. Assuming strategic weapons reductions, the general nuclear war plan, the Single Integrated Operational Plan (SIOP), will change to employ fewer nuclear arms. If stability and threat reduction are authentic goals, the composition of nuclear offensive forces and the SIOP alert force will evolve accordingly. Greater reliance will likely be placed on bombers. The United States and the Soviet Union can use the opportunity provided by perestroika to agree that the only legitimate role of nuclear weapons is to deter nuclear weapons by threatening nuclear reprisal ormore » punishment. Both sides can then share a strategic catechism that would allow them to move toward small reprisal forces.« less

Although traumatic events are presumed to cause sleep disturbances, particularly insomnia, sleep in populations subjected to forced displacement has received little attention. The present study examined the prevalence of insomnia and associated factors in internally displaced persons (IDPs) from Abkhazia 15 years after displacement to Tbilisi. Detailed subjective information about sleep-wake habits, sleep-related and stress-related parameters were obtained from 87 IDPs categorized into good sleepers and insomniacs. The Insomnia Severity Index, Perceived Stress Scale and Beck Depression Inventory were administered. The incidence of insomnia was 41.4%. The majority of insomniacs strongly believed that war-related stress accounted for the onset of their insomnia. Stepwise regression (95% confidence interval) revealed four variables significantly associated with insomnia status: self-estimated influence of war related stress (odds ratio (OR) = 2.51), frequency of nightmares (OR = 1.6), Perceived Stress Scale score (OR = 1.14) and Beck Depression Inventory score (OR = 1.12). Insomnia in IDPs was strongly related to war-associated remembered stress. ‛Over thinking' about major stress exposure enhanced IDPs' vulnerability to insomnia. These findings have implications for the management of insomnia and associated impairment of daytime functioning in IDPs. Copyright © 2011 John Wiley & Sons, Ltd.

The new front in the war on doping: Amateur athletes.

PubMed

Henning, April D; Dimeo, Paul

2018-01-01

The war on drugs is usually associated with criminal policies aimed at stemming consumption of drugs such as heroin, cocaine, and cannabis, less so with enhancement drugs like those used in sport. As drug use in sport, or doping, has become more visibly widespread, policies aimed at combating the issue have become more restrictive, intrusive, and harsh. In this article we draw new comparisons between the wider war on drugs and recent developments in sports anti-doping. We identify a growing trend towards criminalisation of traffickers and users, and associate that with another growing trend: the testing of amateur athletes. This article reviews the current anti-doping system, including the recent amateur policies, then considers of the results of one such program in amateur cycling. We then shift to consider the possible implications for amateurs of criminal doping laws and the recent debates about allowing medical exemptions for therapeutic use of banned substances. We show that drug use in sport can be understood as a new front in the war on drugs, with some extreme measures and many negative unintended consequences. To remedy this, we argue that amateur athletes require a separate anti-doping policy focused on minimising harms of use. Copyright © 2017 Elsevier B.V. All rights reserved.

Nuclear winter - Global consequences of multiple nuclear explosions

1983-01-01

The results of a computerized simulation of the potential global environmental effects of dust and smoke clouds that would be generated by a nuclear war are presented. Short term effects of blast, fire, and radiation are neglected in the series of physical models that include a nuclear war scenario, a particle microphysics model, and a radiative convective model. Account is taken of the altitude-dependent dust, smoke, radioactivity, and NO(x) injections, the temporal evolution of dust and smoke clouds, land and ocean environments, and temperature contrasts. A nuclear exchange would produce thousands of individual smoke and dust clouds rising up to 30 km altitude in the midlatitudes. The smoke, dust, and radioactive debris would cover the entire midlatitudes within 1-2 weeks. The smoke would arise from conflagrations of forests, suburbs, and urban areas. Obscuration of sunlight would induce subfreezing temperatures for several months, disruption of the global circulation patterns, and the arrival of a nuclear winter, followed and accompanied by radioactive fallout, pyrogenic air pollution, and UV-B flux enhancements. It is estimated that a total of only 100 Mtons would be sufficient to plunge the Northern Hemisphere summer to subfreezing temperatures lasting months. Since the probable exchange in a nuclear war would exceed 5000 Mtons, it is expected that many species, including humans, may not survive the war.

Tuneable enhancement of the salt and thermal stability of polymeric micelles by cyclized amphiphiles

2013-01-01

Cyclic molecules provide better stability for their aggregates. Typically in nature, the unique cyclic cell membrane lipids allow thermophilic archaea to inhabit extreme conditions. By mimicking the biological design, the robustness of self-assembled synthetic nanostructures is expected to be improved. Here we report topology effects by cyclized polymeric amphiphiles against their linear counterparts, demonstrating a drastic enhancement in the thermal, as well as salt stability of self-assembled micelles. Furthermore, through coassembly of the linear and cyclic amphiphiles, the stability was successfully tuned for a wide range of temperatures and salt concentrations. The enhanced thermal/salt stability was exploited in a halogen exchange reaction to stimulate the catalytic activity. The mechanism for the enhancement was also investigated. These topology effects by the cyclic amphiphiles offer unprecedented opportunities in polymer materials design unattainable by traditional means. PMID:23481382

Housing the Citizen-Consumer in Post-war Britain: The Parker Morris Report, Affluence and the Even Briefer Life of Social Democracy.

PubMed

Kefford, Alistair

2018-06-01

This article examines debates about the design and provision of post-war housing within the papers and report of the Parker Morris committee. It does so to show how the models of citizens' rights and expectations which underpinned post-war welfare provision were transformed by mass affluence and the dynamic sphere of commercial consumption. Parker Morris's deliberations demonstrate that, as early as the 1950s, the citizen-subject was reimagined as a consuming individual, with requirements based on their expressive needs and consuming desires, and that this had far-reaching consequences for social democratic systems of universal welfare provision. The introduction of consumerist imperatives into publicly defined models of citizens' needs enhanced the political and cultural authority of the commercial domain, prompted a heightened role for commercial experts and market logics within public governance, and served to devalue socialized forms of provision in favour of consumer choice in the private market. The article thus engages with the growing scholarship on the politics of mass consumerism by showing how the material and emotional comforts of post-war affluence came to be constructed as critical to social democratic citizenship and selfhood. Situating this uneasy entanglement of social democratic rights with consumer satisfaction as part of a wider trajectory of political change, the piece suggests that Parker Morris marks an early but significant moment in the transition from post-war welfarism and social democracy to the consumer- and market-oriented forms of governance which came to dominate British politics and society in the latter part of the twentieth century.

A Quasi-Steady Flexible Launch Vehicle Stability Analysis Using Steady CFD with Unsteady Aerodynamic Enhancement

NASA Technical Reports Server (NTRS)

Bartels, Robert E.

2011-01-01

Launch vehicles frequently experience a reduced stability margin through the transonic Mach number range. This reduced stability margin is caused by an undamping of the aerodynamics in one of the lower frequency flexible or rigid body modes. Analysis of the behavior of a flexible vehicle is routinely performed with quasi-steady aerodynamic lineloads derived from steady rigid computational fluid dynamics (CFD). However, a quasi-steady aeroelastic stability analysis can be unconservative at the critical Mach numbers where experiment or unsteady computational aeroelastic (CAE) analysis show a reduced or even negative aerodynamic damping. This paper will present a method of enhancing the quasi-steady aeroelastic stability analysis of a launch vehicle with unsteady aerodynamics. The enhanced formulation uses unsteady CFD to compute the response of selected lower frequency modes. The response is contained in a time history of the vehicle lineloads. A proper orthogonal decomposition of the unsteady aerodynamic lineload response is used to reduce the scale of data volume and system identification is used to derive the aerodynamic stiffness, damping and mass matrices. The results of the enhanced quasi-static aeroelastic stability analysis are compared with the damping and frequency computed from unsteady CAE analysis and from a quasi-steady analysis. The results show that incorporating unsteady aerodynamics in this way brings the enhanced quasi-steady aeroelastic stability analysis into close agreement with the unsteady CAE analysis.

International Astronomical Union was formed after the First World War although it became truly international only after the Second World War. Its Commission 41 on History of Astronomy (C41) was set up in 1948 and in a few years established itself as an active and influential unit. It has the distinction of being a joint Commission, the other partner being International Union of History and Philosophy of Science and Technology (IUHPS). Since IAU is an internationally respected body of professional astronomers, its support for history of astronomy enhances the credibility of the discipline in the eyes of scientists as well as science establishments of individual countries. C41 is committed to advancing objective and rigorous world history of astronomy taking into account all its aspects.

Amone-P'Olak, Kennedy; Omech, Bernard

2018-05-01

Cognitive emotion regulation strategies and mental health problems were assessed in a sample of war-affected youth in Northern Uganda. Univariable and multivariable regression models were fitted to assess the influence of CERS on mental health problems. Maladaptive cognitive emotion regulation strategies (e.g., rumination) were significantly associated with more mental health problems while adaptive cognitive emotion regulation strategies (e.g., putting into perspective) were associated with reporting fewer symptoms of mental health problems. The youth with significant scores on mental health problems (scores ≥ 85th percentile) reported more frequent use of maladaptive than adaptive strategies. Interventions to reduce mental health problems should focus on enhancing the use of adaptive strategies.

Double-Layer Structured CO2 Adsorbent Functionalized with Modified Polyethyleneimine for High Physical and Chemical Stability.

PubMed

Jeon, Sunbin; Jung, Hyunchul; Kim, Sung Hyun; Lee, Ki Bong

2018-06-18

CO 2 capture using polyethyleneimine (PEI)-impregnated silica adsorbents has been receiving a lot of attention. However, the absence of physical stability (evaporation and leaching of amine) and chemical stability (urea formation) of the PEI-impregnated silica adsorbent has been generally established. Therefore, in this study, a double-layer impregnated structure, developed using modified PEI, is newly proposed to enhance the physical and chemical stabilities of the adsorbent. Epoxy-modified PEI and diepoxide-cross-linked PEI were impregnated via a dry impregnation method in the first and second layers, respectively. The physical stability of the double-layer structured adsorbent was noticeably enhanced when compared to the conventional adsorbents with a single layer. In addition to the enhanced physical stability, the result of simulated temperature swing adsorption cycles revealed that the double-layer structured adsorbent presented a high potential working capacity (3.5 mmol/g) and less urea formation under CO 2 -rich regeneration conditions. The enhanced physical and chemical stabilities as well as the high CO 2 working capacity of the double-layer structured adsorbent were mainly attributed to the second layer consisting of diepoxide-cross-linked PEI.

Gulf War veterans were exposed to environmental toxins not present in other combat theaters resulting in a unique biological signature that only partially resembles that seen in other combat veterans with PTSD. Thus it is important to determine if brain abnormalities seen in non-Gulf War veterans with PTSD are also present in Gulf War veterans. In this pilot study, diffusion tensor imaging (DTI) tractography was used to assess the ultra-structural integrity of fronto-limbic white matter connections in Gulf War veterans with and without PTSD. The effects of chronic multisymptom illness on DTI measures was also evaluated. Subjects were 20 previously studied Gulf War veterans on whom MRIs had been obtained. Mean diffusivity (MD) and fractional anisotropy (FA) were determined for left and right cingulum bundle by DTI tractography and compared in separate analyses for 12 veterans with, and 8 without PTSD. The effect of chronic multisymptom illness and it's interaction with PTSD, were similarly investigated using multivariate ACOVA. Partial correlations were used to test the associations of both DTI indices with PTSD severity and plasma cortisol, controlling for whole brain volume. Significantly lower MD was demonstrated in the right cingulum bundle among Gulf War veterans with PTSD. There were no significant differences in MD or FA in the left cingulum bundle. The presence of chronic multisymptom illness significantly attenuated the PTSD associated decrement in right cingulum MD. Clinician and self-rated PTSD symptom severity scores were significantly associated with reduced MD and increased FA in the right cingulum. Similar associations were observed for 8am plasma cortisol in a subset of participants. The preliminary findings indicate increased structural integrity - supporting enhanced connectivity - between right amygdala and anterior cingulate cortex in PTSD. This effect was strongest among Gulf War veterans without chronic multisymptom illness. The association of both MD and FA in the right cingulum with PTSD severity, and with heightened glucocorticoid responsivity, suggests that these DTI findings are a reflection of current PTSD illness expression. Although based on a small sample, these microstructural observations are consistent with a functional model suggesting increased amygdala responsivity in association with anterior cingulate modulation in PTSD.

[Medecine, Law, and Knowledge Production about the "Civilized" War in the Long 19th Century].

PubMed

Goltermann, Svenja

2015-01-01

The aim to 'civilize' warfare accompanied Medicine and International Law ever since the mid-19th century. However, the entanglement of Medicine and Law, crucial for such an endeavour, has not been taken into consideration so far; likewise, the huge importance of medical knowledge for the perception of wars and their ramifications did not garner much attention in historical research. Hence, by focusing on the 'long' 19th century, this paper shows, firstly, that the production of surgical knowledge during warfare aimed at measuring the effects of combat on human bodies in order to develop prognostic medical knowledge for future wars, as well as maintaining the combat strength of soldiers. Moreover, this knowledge production during warfare strived for the enhancement of medical competence in the diagnosis and treatment of wounds in general. Secondly, I show that this medical knowledge was not only relevant for warfare, but also crucial for the design of International Law: it served to nourish the debates among the so called 'civilized' nations about legitimate and illegitimate weaponry and warfare.

Inching toward Armageddon: a psychiatric view.

The existence of thermonuclear arsenals capable of destroying much of humanity takes its origins from, and has an influence on, processes that are largely psychological. The threat to use a single nuclear bomb to resolve contemporary conflict is an anathema in part because complex nation-states did not evolve with surviving a nuclear war in mind. The atomic arms race has proceeded apace because of maladaptive psychological mechanism including denial, distortion, projection, and, most relevantly, the need to enhance bonding within groups by creating stereotypes. One consequence of the arms race is a climate of fear and hopelessness, and especially destructive effect of which is seen in children. The physician's role in the prevention of nuclear war is critical, but divided between contradictory roles. On one hand, the physician is traditionally identified as a non-political advocate of the sick; on the other, as an advocate for the public health. It is this second model that enables physicians most legitimately to work for the prevention of nuclear war and to deal with the psychiatric concomitants of a planet drifting toward disaster.

Our aim was to investigate is there association between level of religious moral beliefs and severity of PTSD symptoms, depressiion symptoms, anxiety and severity of alcohol abuse we tested 152 war veterans on presence of PTSD, depression symptoms, anxiety, alcohol misuse and level of religious moral beliefs. We used Harvard trauma questionnaire (HTQ), Hopkins Check Scale SBCL 25, check list for alcohol misuse MAST. Subjects were assessed with regard to the level of belief in some basic ethical principles that arise from religious moral values. The score of religious moral belief index was used to correlate with severity of PTSD symptoms, depression symptoms, anxiety and severity of alcohol misuse. Mean age of tested subjects was 40.8 (SD=6.6) years. The score of the moral belief index was negatively correlated to PTSD symptom severity and depressiveness (Pearson's r=-0.325, p<0.001; r=-0.247, p=0.005, respectively). Besides that the score of moral belief index negatively correlated with presented anxiety (Pearson's r=-0.199,p=0.026). Related to severity of tobacco and alcohol misuse we found negative association of these with the moral belief index (Pearson's r=-0.227, p=0.011; r=-0.371, p<0.001, respectively). A higher index of religious moral beliefs in war veterans enables better control distress, providing better mental health stability. It enables post traumatic conflicts typical for combatants' survivors to be more easily overcome. It also causes healthier reactions to external stimuli. A higher index of religious moral beliefs of war veterans provides a healthier and more efficient mechanism of tobacco and alcohol misuse control. In this way, it helps overcoming postwar psychosocial problems and socialization of the personality, leading to the improvement in mental health.

Mobile technologies offer potentially critical ways of delivering mental health support to those experiencing war, ethnic conflict, and human-caused and natural disasters. Research on Internet interventions suggests that effective mobile mental health technologies can be developed, and there are early indications that they will be acceptable to war and disaster survivors, and prove capable of greatly increasing the reach of mental health services. Promising mhealth interventions include video teleconferencing, text messaging, and smartphone-based applications. In addition, a variety of social media platforms has been used during and immediately after disasters to increase agility in responding, and strengthen community and individual resilience. Globally, PTSD Coach has been downloaded over 243,000 times in 96 countries, and together with large-scale use of social media for communication during disasters, suggests the potential for reach of app technology. In addition to enabling improved self-management of post-trauma problems, mobile phone interventions can also enhance delivery of face-to-face care by mental health providers and increase the effectiveness of peer helpers and mutual aid organizations. More research is needed to establish the efficacy of mhealth interventions for those affected by war and disaster. Research should also focus on the identification of active elements and core processes of change, determination of effective ways of increasing adoption and engagement, and explore ways of combining the various capabilities of mobile technologies to maximize their impact.

The aim of this study was to examine the effect of peer group support on family adaptation of wives of war veterans suffering from post-traumatic stress disorder (PTSD). In this randomized controlled trial, 80 wives of war veterans with PTSD were incorporated, and selected participants were randomly assigned into intervention and control groups (n = 40 per group). The intervention group was divided into four subgroups, with each participating in eight weekly based 1.5-hr peer support group sessions and the control group received no intervention. Demographics form and Family Adaptation Scale (FAS) developed by Antonovsky and Sourani (1988) were applied. The total mean scores of family adaptation increased significantly more in the intervention group than in the control group (p = .033). Furthermore, the time × group interaction effects were significant for internal family fit (p = .013) and a combination of both family fit and family community fit (p = .020) dimensions. Nonetheless family fit dimensions mean scores had no significant increase in the intervention group than the control group over time (p = .948). Peer support group can be a useful tool for health care professionals to enhance family adaptation in spouses of war veterans with PTSD. © 2017 Wiley Periodicals, Inc.

Long-term follow-up of unilateral transfemoral amputees from the Vietnam war.

2003-04-01

Despite their frequency, few reports exist concerning the initial and long-term consequences of battle-incurred unilateral transfemoral amputations. A retrospective cohort design was used to measure the long-term health of transfemoral battle amputees treated at a single hospital during the Vietnam War. Data collection consisted of medical record abstraction and a follow-up questionnaire that included the SF-36 Health Survey. Forty-six patients responded to the survey an average of 28 years after injury. Compared with the controls, patient responses to the SF-36 were significantly (p < 0.01) less in all categories except Mental Health and Vitality. Forty-three (93.5%) are or have been married. Forty-one (89.1%) are or have been employed an average of 20.1 years. Forty patients (87%) wore a prosthesis an average of 13.5 h/day. Although the patients do relatively well with employment and marriage stability, the low SF-36 scores suggest a significant disability.

Both solubility and chemical stability of curcumin are enhanced by solid dispersion in cellulose derivative matrices.

Amorphous solid dispersions (ASD) of curcumin (Cur) in cellulose derivative matrices, hydroxypropylmethylcellulose acetate succinate (HPMCAS), carboxymethylcellulose acetate butyrate (CMCAB), and cellulose acetate adipate propionate (CAAdP) were prepared in order to investigate the structure-property relationship and identify polymer properties necessary to effectively increase Cur aqueous solution concentration. XRD results indicated that all investigated solid dispersions were amorphous, even at a 9:1 Cur:polymer ratio. Both stability against crystallization and Cur solution concentration from these ASDs were significantly higher than those from physical mixtures and crystalline Cur. Remarkably, curcumin was also stabilized against chemical degradation in solution. Chemical stabilization was polymer-dependent, with stabilization in CAAdP>CMCAB>HPMCAS>PVP, while matrices enhanced solution concentration as PVP>HPMCAS>CMCAB≈CAAdP. HPMCAS/Cur dispersions have useful combinations of pH-triggered release profile, chemical stabilization, and strong enhancement of Cur solution concentration. Copyright © 2013 Elsevier Ltd.

Scenarios of changes in temperature, precipitation, and downward shortwave radiation from the ModelE and WACCM simulations, applied to the Decision Support System for Agrotechnology Transfer crop model for winter wheat, rice, soybeans, and maize by perturbing observed time series with anomalies from the regional nuclear war simulations, produce decreases of 10-50% in yield averaged over a decade, with larger decreases in the first several years, over the midlatitudes of the Northern Hemisphere. The impact of the nuclear war simulated here, using much less than 1% of the global nuclear arsenal, would be devastating to world agricultural production and trade, possibly sentencing a billion people now living marginal existences to starvation.The continued environmental threat of the use of even a small number of nuclear weapons must be considered in nuclear policy deliberations in Russia, the U.S., and the rest of the world.

Successful Stabilization of Graphene Oxide in Electrolyte Solutions: Enhancement of Bio-functionalization and Cellular Uptake

2013-01-01

Aqueous dispersions of graphene oxide are inherently unstable in the presence of electrolytes, which screen the electrostatic surface charge on these nanosheets and induce irreversible aggregation. Two complementary strategies, utilizing either electrostatic or steric stabilization, have been developed to enhance the stability of graphene oxide in electrolyte solutions, allowing it to stay dispersed in cell culture media and serum. The electrostatic stabilization approach entails further oxidation of graphene oxide to low C/O ratio (~1.03) and increases ionic tolerance of these nanosheets. The steric stabilization technique employs an amphiphilic block copolymer that serves as a non-covalently bound surfactant to minimize the aggregate-induced nanosheets-nanosheet interactions. Both strategies can stabilize graphene oxide nanosheets with large dimensions (>300 nm) in biological media, allowing for an enhancement of >250% in the bioconjugation efficiency of streptavidin in comparison to untreated nanosheets. Notably, both strategies allow the stabilized nanosheets to be readily uptake by cells, demonstrating their excellent performance as potential drug delivery vehicles. PMID:22017285

This study investigated the potential of gum arabic to improve the stability of anthocyanins that are used in commercial beverages as natural colourants. The degradation of purple carrot anthocyanin in model beverage systems (pH 3.0) containing L-ascorbic acid proceeded with a first-order reaction rate during storage (40 °C for 5 days in light). The addition of gum arabic (0.05-5.0%) significantly enhanced the colour stability of anthocyanin, with the most stable systems observed at intermediate levels (1.5%). A further increase in concentration (>1.5%) reduced its efficacy due to a change in the conformation of the gum arabic molecules that hindered their exposure to the anthocyanins. Fluorescence quenching measurements showed that the anthocyanin could have interacted with the glycoprotein fractions of the gum arabic through hydrogen bonding, resulting in enhanced stability. Overall, this study provides valuable information about enhancing the stability of anthocyanins in beverage systems using natural ingredients. Copyright © 2016 Elsevier Ltd. All rights reserved.

Pseudo-materials are effective in boosting the specific capacitance of supercapacitors, but during service their degradation may also be very strong, causing reduced cycling stability. Here, we show that a carbon nanotube sponge grafted by two conventional pseudo-polymer layers in sequence can serve as a porous supercapacitor electrode with significantly enhanced cycling stability compared with single polymer grafting. Creating conformal polymer coatings on the nanotube surface and the resulting double-sheath configuration are important structural factors leading to the enhanced performance. Combining different polymers as double sheaths as reported here might be a potential route to circumvent the dilemma of pseudo-materials, and to simultaneously improve the capacitance and stability for various energy storage devices.Pseudo-materials are effective in boosting the specific capacitance of supercapacitors, but during service their degradation may also be very strong, causing reduced cycling stability.

Mood and Memory Deficits in a Model of Gulf War Illness Are Linked with Reduced Neurogenesis, Partial Neuron Loss, and Mild Inflammation in the Hippocampus

Impairments in mood and cognitive function are the key brain abnormalities observed in Gulf war illness (GWI), a chronic multisymptom health problem afflicting ∼25% of veterans who served in the Persian Gulf War-1. Although the precise cause of GWI is still unknown, combined exposure to a nerve gas prophylaxis drug pyridostigmine bromide (PB) and pesticides DEET and permethrin during the war has been proposed as one of the foremost causes of GWI. We investigated the effect of 4 weeks of exposure to Gulf war illness-related (GWIR) chemicals in the absence or presence of mild stress on mood and cognitive function, dentate gyrus neurogenesis, and neurons, microglia, and astrocytes in the hippocampus. Combined exposure to low doses of GWIR chemicals PB, DEET, and permethrin induced depressive- and anxiety-like behavior and spatial learning and memory dysfunction. Application of mild stress in the period of exposure to chemicals exacerbated the extent of mood and cognitive dysfunction. Furthermore, these behavioral impairments were associated with reduced hippocampal volume and multiple cellular alterations such as chronic reductions in neural stem cell activity and neurogenesis, partial loss of principal neurons, and mild inflammation comprising sporadic occurrence of activated microglia and significant hypertrophy of astrocytes. The results show the first evidence of an association between mood and cognitive dysfunction and hippocampal pathology epitomized by decreased neurogenesis, partial loss of principal neurons, and mild inflammation in a model of GWI. Hence, treatment strategies that are efficacious for enhancing neurogenesis and suppressing inflammation may be helpful for alleviation of mood and cognitive dysfunction observed in GWI.

A Review of Military Health Research Using a Social-Ecological Framework.

We aim to contextualize the growing body of research on the sequelae of military service in the wars in Afghanistan and Iraq. We employ a social-ecological (SE) framework for the taxonomy of military health research and classify risk as arising from the individual, family, community, and the institutional levels. We intend for this review to inform enhanced health promotion efforts in military communities. Articles reviewed were extracted from Web of Science, PubMed, and Scopus. Research focused on somatic and psychological sequelae of combat deployment published from 2001-the year the war in Afghanistan began-through the end of 2014. We excluded studies of non-US military personnel, other systematic reviews, meta-analyses, book chapters, and theoretical papers. We examined and summarized the aims, participants, methods, study design, SE framework tier, risk factors, and health outcomes. Studies were categorized according to SE tier, whether they focused on somatic, behavioral, or psychological outcomes, and by risk factor. Of the 352 peer-reviewed papers, 84% focused on war's sequelae on the index military personnel, and 75% focused on mental or behavioral health outcomes-mostly on post-traumatic stress disorder. We find comparatively little research focusing on the family, community, or institutional tiers. We know relatively little about how family and community respond to the return of personnel from combat deployment; how family resources affect the health of returning military personnel; and how a war's persistence presents challenges for federal, state, and local agencies to meet military health-care needs. Such work is especially salient as US troops return home from war-particularly in communities where there are substantial military populations.

Enhanced Physical Stability of Amorphous Drug Formulations via Dry Polymer Coating.

PubMed

Capece, Maxx; Davé, Rajesh

2015-06-01

Although amorphous solid drug formulations may be advantageous for enhancing the bioavailability of poorly soluble active pharmaceutical ingredients, they exhibit poor physical stability and undergo recrystallization. To address this limitation, this study investigates stability issues associated with amorphous solids through analysis of the crystallization behavior for acetaminophen (APAP), known as a fast crystallizer, using a modified form of the Avrami equation that kinetically models both surface and bulk crystallization. It is found that surface-enhanced crystallization, occurring faster at the free surface than in the bulk, is the major impediment to the stability of amorphous APAP. It is hypothesized that a novel use of a dry-polymer-coating process referred to as mechanical-dry-polymer-coating may be used to inhibit surface crystallization and enhance stability. The proposed process, which is examined, simultaneously mills and coats amorphous solids with polymer, while avoiding solvents or solutions, which may otherwise cause stability or crystallization issues during coating. It is shown that solid dispersions of APAP (64% loading) with a small particle size (28 μm) could be prepared and coated with the polymer, carnauba wax, in a vibratory ball mill. The resulting amorphous solid was found to have excellent stability as a result of inhibition of surface crystallization. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association.

δ-Catenin Increases the Stability of EGFR by Decreasing c-Cbl Interaction and Enhances EGFR/Erk1/2 Signaling in Prostate Cancer.

δ-Catenin, a member of the p120-catenin subfamily of armadillo proteins, reportedly increases during the late stage of prostate cancer. Our previous study demonstrates that δ-catenin increases the stability of EGFR in prostate cancer cell lines. However, the molecular mechanism behind δ-catenin-mediated enhanced stability of EGFR was not explored. In this study, we hypothesized that δ-catenin enhances the protein stability of EGFR by inhibiting its lysosomal degradation that is mediated by c-casitas b-lineage lymphoma (c-Cbl), a RING domain E3 ligase. c-Cbl monoubiquitinates EGFR and thus facilitates its internalization, followed by lysosomal degradation. We observed that δ-catenin plays a key role in EGFR stability and downstream signaling. δ-Catenin competes with c-Cbl for EGFR binding, which results in a reduction of binding between c-Cbl and EGFR and thus decreases the ubiquitination of EGFR. This in turn increases the expression of membrane bound EGFR and enhances EGFR/Erk1/2 signaling. Our findings add a new perspective on the role of δ-catenin in enhancing EGFR/Erk1/2 signaling-mediated prostate cancer.

Military pain management in 21st century war.

Buckenmaier, Chester C; Griffith, Scott

2010-07-01

Morphine and other opioid drugs have played a major role in austere environment pain management since the Civil War, particularly in the military. While the pre-eminence and success of such medications is without question, their use is accompanied by significant side effects that are undesirable in the most advanced medical settings, and are potentially devastating in the field environment. Recently, there have been significant improvements in pain care for America's wounded service members, along with a shift in how many care providers view pain management. An increasing number of healthcare providers are seeing pain not merely as a symptom, but as a disease process. In addition to dramatically improving care for wounded service members, the evolution in the military's approach to pain is enhancing care for civilians.

Conflict, sticks and carrots: war increases prosocial punishments and rewards.

PubMed

Gneezy, Ayelet; Fessler, Daniel M T

Unlike most species, humans cooperate extensively with group members who are not closely related to them, a pattern sustained in part by punishing non-cooperators and rewarding cooperators. Because internally cooperative groups prevail over less cooperative rival groups, it is thought that violent intergroup conflict played a key role in the evolution of human cooperation. Consequently, it is plausible that propensities to punish and reward will be elevated during intergroup conflict. Using experiments conducted before, during and after the 2006 Israel-Hezbollah war, we show that, during wartime, people are more willing to pay costs to punish non-cooperative group members and reward cooperative group members. Rather than simply increasing within-group solidarity, violent intergroup conflict thus elicits behaviours that, writ large, enhance cooperation within the group, thereby making victory more likely.

Rational Design of Biobetters with Enhanced Stability.

Biotherapeutics are the fastest growing class of pharmaceutical with a rapidly evolving market facing the rise of biosimilar and biobetter products. In contrast to a biosimilar, which is derived from the same gene sequence as the innovator product, a biobetter has enhanced properties, such as enhanced efficacy or reduced immunogenicity. Little work has been carried out so far to increase the intrinsic stability of biotherapeutics via sequence changes, even though, aggregation, the primary degradation pathway of proteins, leads to issues ranging from manufacturing failure to immunological response and to loss of therapeutic activity. Using our spatial aggregation propensity tool as a first step to a rational design approach to identify aggregation-prone regions, biobetters of rituximab have been produced with enhanced stability by introducing site-specific mutations. Significant stabilization against aggregation was achieved for rituximab with no decrease in its binding affinity to the antigen. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association.

We numerically investigate how a vertical external magnetic field affects the convective flow in a Rayleigh-Benard turbulent convection. We observed an enhancement of heat transport under certain range of the Hartmann number Ha that characterizes the strength of the stabilizing Lorentz force. Heat transport enhancement caused by a stabilizing force is also observed in several other systems. We find that the heat transport behaviour in the present system may also be understood in terms of an interplay between the stabilizing and destabilizing forces of the system and the observed optimum heat transport enhancement can be explained by an optimal coupling between thermal boundary layer and the momentum boundary layer. Therefore, the observed behaviour in magnetoconvection appears to belong to the same universality class of stabilizing-destabilizing (SD) flows reported recently.

Entropic stabilization of native protein structures typically relies on strategies that serve to decrease the entropy of the unfolded state. Here we report, using a combination of experimental and computational approaches, on enhanced thermodynamic stability conferred by an increase in the configurational entropy of the folded state. The enhanced stability is observed upon modifications of a loop region in the enzyme acylphosphatase and is achieved despite significant enthalpy losses. The modifications that lead to increased stability, as well as those that result in destabilization, however, strongly compromise enzymatic activity, rationalizing the preservation of the native loop structure even though it does not provide the protein with maximal stability or kinetic foldability.

Conflict, famine and the arms trade.

Judd, F

Armed conflict has had horrendous humanitarian effects, causing 22 million deaths, over 80 per cent of them civilian, since 1945 and resulting today in 19 million refugees and 24 million displaced persons. War results in economic collapse, and high levels of military spending decrease regional stability. Benefits to the producers are limited or negative and developed countries should diversify away from arms production. There is a need for greater awareness in the developed countries, an end to the secrecy besetting the arms trade, and restructuring of the industry. A Code of Conduct governing arms exports is proposed.

Stabilization of Li Metal Anode in DMSO-Based Electrolytes via Optimization of Salt-Solvent Coordination for Li-O 2 Batteries

DOE Office of Scientific and Technical Information (OSTI.GOV)

Liu, Bin; Xu, Wu; Yan, Pengfei

The conventional DMSO-based electrolyte (1 M lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in DMSO) is unstable against the Li metal anode and therefore cannot be used directly in practical Li-O2 batteries. Here, we demonstrate that a highly concentrated electrolyte based on LiTFSI in DMSO (with a molar ratio of 1:3) can greatly improve the stability of the Li metal anode against DMSO and significantly improve the cycling stability of Li-O2 batteries. This highly concentrated electrolyte contains no free DMSO solvent molecules, but only complexes of (TFSI–)a-Li+-(DMSO)b (where a + b = 4), and thus enhances their stability with Li metal anodes. In addition,more » such salt-solvent complexes have higher Gibbs activation energy barriers than the free DMSO solvent molecules, indicating improved stability of the electrolyte against the attack of superoxide radical anions. Therefore, the stability of this highly concentrated electrolyte at both Li metal anodes and carbon-based air electrodes has been greatly enhanced, resulting in improved cyclic stability of Li-O2 batteries. The fundamental stability of the electrolyte with free-solvent against the chemical and electrochemical reactions can also be used to enhance the stability of other electrochemical systems.« less

Geological and Tectonic Evidence for the Formation and Extensional Collapse of the West Antarctic Plateau: Implications for the Formation of the West Antarctic Rift System and the Transantarctic Mountains

NASA Astrophysics Data System (ADS)

Fitzgerald, P. G.; Studinger, M.; Bialas, R. W.; Buck, W.

2007-12-01

The Transantarctic Mountains (TAM), the world's longest and highest non-contractional intracontinental mountain belt, define the western boundary of the West Antarctic rift system (WARS). The WARS is a broad region of extended continental lithosphere, ca. 750-1000 km wide, lying dominantly below sea-level. A new model (Bialas et al., 2007), proposes that a region of thickened continental crust and high-standing topography, the "West Antarctic Plateau", underwent extensional collapse to leave a remnant edge representing the proto-TAM. Tectonic and paleogeographic reconstructions indicate the plateau formed inboard of a continental arc along the paleo- Pacific margin of Antarctica, active throughout the Paleozoic until the late Mesozoic. This high-standing region was responsible for confining sediments (Beacon Supergroup) to elongate basins along the length of the TAM. Much of the present region of the WARS has been correlated with the Lachlan Fold belt of southeastern Australia. This belt formed from the Ordovician to Carboniferous during back-arc basin formation associated with slab roll- back with short periods of compression. Convergence along the paleo-Pacific margin, perhaps enhanced by subduction of more buoyant oceanic lithosphere as the Phoenix-Pacific ridge was obliquely subducted, resulted in crustal thickening and formation of high-standing terrain (the plateau). Extensional collapse of the plateau most likely began in the Jurassic during initial rifting between East and West Antarctica, but was mainly accomplished during distributed rifting in the Cretaceous (ca. 105-85) following subduction of the Phoenix-Pacific ridge and prior to the separation of New Zealand from Marie Byrd Land. Continued formation of the TAM continued in the Cenozoic concomitant with extension in the WARS that was localized along its western margin adjacent to the TAM. Glacial erosion in the Oligocene and early-Miocene enhanced peak height in the TAM. In this presentation we discuss the diverse geological, geophysical, thermochronological and tectonic evidence for the West Antarctic Plateau and the implications for the formation of the Transantarctic Mountains.

2009-01-01

This phenomenological study explores the experiences and perceptions of the telling of life stories of four post-war immigrants living in a multicultural residential aged-care setting in Australia. This study aims to shed light on what participants feel about life stories, and the prospect of involvement in the documentation of their life story in order to provide insight and understanding for optimum programme facilitation and better resident care.Semi-structured interviews were conducted with the four participants. Data were audiotaped and transcribed. Phenomenological methods were used to explicate data.Three main themes emerged: diminution of guilt, social sharing - common bonds and, the urge to 'feel' the past to 'fill' the present. It is apparent that aged survivors of war, and displacement to a new country, feel residual guilt regarding the leaving of their homeland. The prospect of documenting their life stories offers an opportunity to provide an explanation for their decision.Immersion in life stories allows the re-experiencing and sharing of past emotions and sensations. Engagement in occupational reminiscence enhances understanding a person's lived life experience, which adds meaning to one's life. Copyright (c) 2009 John Wiley & Sons, Ltd.

Improving the stability of subnano-MoO3/meso-SiO2 catalyst through amino-functionalization

NASA Astrophysics Data System (ADS)

Wang, Jiasheng; Wu, Wenpei; Yang, Qianfan; Wang, Wan-Hui; Bao, Ming

Subnano-MoO3 clusters (below 1nm) have excellent catalytic activity on oxidative desulfurization (ODS). However, the stability is not very satisfactory due to the leaching of MoO3 during the reaction. To enhance the stability, here we developed a method by grafting NH2 to silica. NH2 could form coordination bond with MoO3, as proved by solid state 1H NMR, which can prevent MoO3 from leaching and thus significantly enhance the stability.

Some socio-economic aspects of population growth in the USSR.

PubMed

Simchera, V

1974-01-01

This summarizes population trends in the U.S.S.R. since the early 19 00's. On August 9, 1973, the population topped 250 million, almost precisely double that of Russia at the time of the 1st general census in 1897. Since 1922 it had increased by more than 84%. Russia has suffered more population loss in wars than any other country in modern times. The First World War, the Civil War, and the Second World War took a toll of more than 30 million, more than 20 million during the Second World War alone. The extent of these loses can be judged from the following: between 1897 and 1913 the population of Russia increased at the rate of 1.55% per annum or 34.6 million; if this had continued the population would have been at least 182.8 million by the end of 1922. As it was, the population was 136.1 million by 1922 and the hypothetical 182.8 million was not reached until 1952. More than 4/5 of today's population have been born since the October Revolution. Only 43 million were born before the revolution and only 7.5 were born in the last century. The economic base has grown much more rapidly than the population. For the period 1940-1972 the population increased 1.27 times, national income 9.51 times, fixed assets, 8.76 times, industrial production, 13.65 times, agricultural output, 2.14 times, and capital investment 14.52 times. The birthrate has been falling since World War 1 but total population growth has increased steadily. Birthrates have declined from 45.5/1000 in 1913 to 17.8/1000 in 1972 and a slight upturn is seen. It is expected that the birthrate will continue to increase slightly, then stabilize. Much of the population increase has come from significantly reduced mortality rates. 1st and 2nd children now account for 71% of all births. Family allowances, child care, free health care, and other social benefits encourage births while high employment levels for women, a shortage of men in the marriageable age ranges, and late marriages tend to depress the birthrate. The shortage of men is directly the result of the losses during World War 2. Employment opportunities have changed dramatically. The country has gone from a primarily agricultural nation to one in which 80% of the people are working class wage or salary earners. The current problem is closing the urban-rural gap and equalizing population density. 3/5 of the people are town-dwellers. To fight declining population in the villages and in the areas of Siberia and the Far East, new towns and new industrial and cultural centers are being established such as Bratsk, Ust-Ilim, Norilsk, and others.

Amorphous stabilization and dissolution enhancement of amorphous ternary solid dispersions: combination of polymers showing drug-polymer interaction for synergistic effects.

PubMed

Prasad, Dev; Chauhan, Harsh; Atef, Eman

2014-11-01

The purpose of this study was to understand the combined effect of two polymers showing drug-polymer interactions on amorphous stabilization and dissolution enhancement of indomethacin (IND) in amorphous ternary solid dispersions. The mechanism responsible for the enhanced stability and dissolution of IND in amorphous ternary systems was studied by exploring the miscibility and intermolecular interactions between IND and polymers through thermal and spectroscopic analysis. Eudragit E100 and PVP K90 at low concentrations (2.5%-40%, w/w) were used to prepare amorphous binary and ternary solid dispersions by solvent evaporation. Stability results showed that amorphous ternary solid dispersions have better stability compared with amorphous binary solid dispersions. The dissolution of IND from the ternary dispersion was substantially higher than the binary dispersions as well as amorphous drug. Melting point depression of physical mixtures reveals that the drug was miscible in both the polymers; however, greater miscibility was observed in ternary physical mixtures. The IR analysis confirmed intermolecular interactions between IND and individual polymers. These interactions were found to be intact in ternary systems. These results suggest that the combination of two polymers showing drug-polymer interaction offers synergistic enhancement in amorphous stability and dissolution in ternary solid dispersions. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association.

The enhanced anti-tissue adhesive effect of injectable pluronic-HA hydrogel by poly(γ-glutamic acid).

Kim, Manse; Hwang, Youngmin; Tae, Giyoong

The stability of tissue barrier in physiological condition is a key factor to isolate the damaged site from adjacent tissue for anti-tissue adhesion. Although pluronic or pluronic-hyaluronic acid (HA) hydrogel as an injectable formulation can prevent tissue adhesion at the injection site, the anti-tissue adhesion effect is limited due to its poor stability. Herein, we prepared tissue barrier formulations composed of pluronic F127 (F127) and HA mixture (F127-HA) and the effect of the addition of poly(γ-glutamic acid) (PGA) was characterized. All of F127, HA, and F127-HA mixture showed the poor in vitro residence stability less than 3 days. However, by adding PGA into F127-HA mixture, their stability was significantly enhanced by the control of the molecular weight and concentration of PGA. Thus, F127-HA with 10wt% PGA (2000kDa) showed the long-term stability over 10 days. Similarly, the enhanced stability of F127-HA with PGA resulted in the enhanced and excellent in vivo anti-tissue adhesion effect, evidenced by histological analysis and grading of tissue adhesion. Therefore, F127-HA containing PGA could be applied as an efficient injectable tissue barrier for anti-tissue adhesion. Copyright © 2016 Elsevier B.V. All rights reserved.

Frequency stability improvement for piezoresistive micromechanical oscillators via synchronization

NASA Astrophysics Data System (ADS)

Pu, Dong; Huan, Ronghua; Wei, Xueyong

2017-03-01

Synchronization phenomenon first discovered in Huygens' clock shows that the rhythms of oscillating objects can be adjusted via an interaction. Here we show that the frequency stability of a piezoresistive micromechanical oscillator can be enhanced via synchronization. The micromechanical clamped-clamped beam oscillator is built up using the electrostatic driving and piezoresistive sensing technique and the synchronization phenomenon is observed after coupling it to an external oscillator. An enhancement of frequency stability is obtained in the synchronization state. The influences of the synchronizing perturbation intensity and frequency detuning applied on the oscillator are studied experimentally. A theoretical analysis of phase noise leads to an analytical formula for predicting Allan deviation of the frequency output of the piezoresistive oscillator, which successfully explains the experimental observations and the mechanism of frequency stability enhancement via synchronization.

Conflict, sticks and carrots: war increases prosocial punishments and rewards

PubMed Central

Gneezy, Ayelet; Fessler, Daniel M. T.

2012-01-01

Unlike most species, humans cooperate extensively with group members who are not closely related to them, a pattern sustained in part by punishing non-cooperators and rewarding cooperators. Because internally cooperative groups prevail over less cooperative rival groups, it is thought that violent intergroup conflict played a key role in the evolution of human cooperation. Consequently, it is plausible that propensities to punish and reward will be elevated during intergroup conflict. Using experiments conducted before, during and after the 2006 Israel–Hezbollah war, we show that, during wartime, people are more willing to pay costs to punish non-cooperative group members and reward cooperative group members. Rather than simply increasing within-group solidarity, violent intergroup conflict thus elicits behaviours that, writ large, enhance cooperation within the group, thereby making victory more likely.

1998-01-01

An autobiography, of a noted aeronautical engineer, W. Hewitt Phillips, whose career spanned 58 years (1940-1998) at NASA Langley is presented. This work covers his early years to the Sputnik launch. His interests have been in research in aeronautics and in the related problems of spaceflight. After an introduction, his early life through the college years is reviewed, and his early interest in model airplanes is described. The first assignment for the National Advisory Committee for Aeronautics (NACA), which would later become NASA, was with the Flight Research Division. His early work involved "Flying Qualities", i.e., the stability and control characteristics of an airplane. The next chapter describes his early analytical studies. His work during World War II in the design of military airplanes, and the other effects of the war on research activities, is covered in the next two chapters. This research was involved in such innovations and refinements as the swept wing, the flettner tabs, servo tabs, spring tabs and whirlerons. The rest of the work covers the research which Mr. Hewitt was involved in, after the war until the Sputnik launch. These areas include unsteady lift, measurements of turbulence in the atmosphere, gust alleviation, and lateral response to random turbulence. He was also involved in several investigations of airplane accidents. The last two chapters cover the administration of the Langley Research Center, and the dawn of the Space Age. A complete bibliography of reports written by Mr. Hewitt, is included.

Nuclear deterrence in the Arab-Israeli conflict. A case study in Egyptian-Israeli relations

1986-01-01

In order to achieve security and stability, and maximize the chances for resolving the Arab-Israeli conflict, should Egypt and Israel adopt declared nuclear deterrence doctrines. Or would such a move be ineffective, dangerous, or even disastrous. The nuclearization of the Middle East is not necessary: military threats to the survival of the states in the region do not justify the introduction of nuclear weapons. Nuclearization is not desirable: deterrence theory's assumptions and implications exhibit intellectual weakness and its explanatory power is unsatisfactory; nuclear deterrence may reduce the frequency of war, but it pays little attention to the consequences of war;more » and in comparison to defense, nuclear deterrence may lack credibility. Presently, Israel has nuclear capability and delivery systems sufficient to provide security to its vital areas through deterrence of or defense against Arab attacks. The Arabs do not, however, believe that such security extends to the Arab territories occupied by Israel during the June 1967 war. To supply security, nuclear deterrence must be effective, stable, and credible. In a multinuclear environment, the Egyptians and Israelis are likely to meet the requirement for an effective deterrence: the possession of a nuclear capability sufficient to inflict an enormous amount of death and destruction. If the Arabs and Israelis sought and adopted strategies of deterrence, they might be able to meet the requirement for a stable deterrence: the acquisition of second strike capabilities.« less

N-Allyl- N, N-Bis(trimethylsilyl)amine as a Novel Electrolyte Additive To Enhance the Interfacial Stability of a Ni-Rich Electrode for Lithium-Ion Batteries.

Enhancing the electrode/electrolyte interface stability of high-capacity LiNi 0.8 Co 0.15 Al 0.05 O 2 (LNCA) cathode material is urgently required for its application in next-generation lithium-ion battery. Herein, we demonstrate that enhanced interfacial stability of LNCA can be achieved by simply introducing 2 wt % N-allyl- N, N-bis(trimethylsilyl)amine (NNB) electrolyte additive. Electrolyte oxidation reactions and electrode structural destruction are greatly suppressed in the electrolyte with NNB additive, leading to improved cyclic stability of LNCA from 72.8 to 86.2% after 300 cycles. The mechanism of NNB on improving the cyclic stability of LNCA has been verified to its excellent solid electrolyte interface (SEI) film-forming capability. Moreover, the X-ray diffraction and X-ray photoelectron spectroscopy results indicate that the NNB-derived Si-containing SEI film restrains the Li/Ni disorder of LNCA during cycling, which further improves the cyclic stability of Ni-rich LNCA. Importantly, the charging/discharging test reveals that the NNB additive effectively improves the cyclic stability of the LNCA/graphite full cell.

Examination of molecular mechanism for the enhanced thermal stability of anthocyanins by metal cations and polysaccharides.

Anthocyanins exhibit colour variation over wide pH range but the colour stability is relatively low at the physiological pH. To improve the stability of anthocyanins in neutral to weakly acidic pH region, effects of metal cations and polysaccharides on the colour stability of cyanidin-3-glucoside (C3G) were examined by ultraviolet-visible and resonance Raman spectroscopies. C3G was thermally stabilized by the addition of Fe(3+) but formed aggregation. However, further addition of anionic polysaccharides enhanced the thermal stability of C3G without aggregation. Similar stabilisation was confirmed for delphinidin-3-glucoside (D3G) but not for pelargonidin-3-glucoside. The stability of anthocyanins considerably varied depending on pHs and kinds of metal cations, polysaccharides and buffer molecules. The characteristic resonance Raman bands of C3G-Fe(3+) and D3G-Fe(3+) complexes were significantly affected by the addition of alginate, (18)O/(16)O-isotope substitution, and Fe(2+)/Fe(3+)-replacement. These results suggest that alginate associates with C3G through Fe(3+) to form a stable complex, which enhances the thermal stability of C3G. Copyright © 2013 Elsevier Ltd. All rights reserved.

Cells routinely compartmentalize enzymes for enhanced efficiency of their metabolic pathways. Here we report a general approach to construct DNA nanocaged enzymes for enhancing catalytic activity and stability. Nanocaged enzymes are realized by self-assembly into DNA nanocages with well-controlled stoichiometry and architecture that enabled a systematic study of the impact of both encapsulation and proximal polyanionic surfaces on a set of common metabolic enzymes. Activity assays at both bulk and single-molecule levels demonstrate increased substrate turnover numbers for DNA nanocage-encapsulated enzymes. Unexpectedly, we observe a significant inverse correlation between the size of a protein and its activity enhancement. This effect is consistent with a model wherein distal polyanionic surfaces of the nanocage enhance the stability of active enzyme conformations through the action of a strongly bound hydration layer. We further show that DNA nanocages protect encapsulated enzymes against proteases, demonstrating their practical utility in functional biomaterials and biotechnology.

Enhanced stability of ZnO-based inverted organic photovoltaic devices by phosphonic acid modification

2014-03-01

Solution-processed ZnO thin films are now commonly used as n-type bottom contacts in inverted-geometry organic photovoltaics (OPVs). The use of ZnO eliminates the need for highly-reactive top-contact (air-interface) electrode material, such as calcium and aluminum which are commonly used in conventional geometries, which enables operational lifetimes of unencapsulated devices to shift from minutes or hours to days. Modification of the ZnO film by self-assembled monolayers (SAMs) has been shown to enhance performance as well as air-stability during storage. We modify ZnO with dipolar phosphonic acids and observe enhanced performance and stability. We show for the first time devices measured under continuous illumination at one-sun intensity which have significantly enhanced stability when utilizing SAM-modified ZnO. These continuous-illumination stability measurements allow us to investigate the degradation mechanisms of these more stable inverted OPV devices.

Enhanced Luminescent Stability through Particle Interactions in Silicon Nanocrystal Aggregates

2015-10-27

Close-packed assemblies of ligand-passivated colloidal nanocrystals can exhibit enhanced photoluminescent stability, but the origin of this effect is unclear. Here, we use experiment, simulation, and ab initio computation to examine the influence of interparticle interactions on the photoluminescent stability of silicon nanocrystal aggregates. The time-dependent photoluminescence emitted by structures ranging in size from a single quantum dot to agglomerates of more than a thousand is compared with Monte Carlo simulations of noninteracting ensembles using measured single-particle blinking data as input. In contrast to the behavior typically exhibited by the metal chalcogenides, the measured photoluminescent stability shows an enhancement with respectmore » to the noninteracting scenario with increasing aggregate size. We model this behavior using time-dependent density functional theory calculations of energy transfer between neighboring nanocrystals as a function of nanocrystal size, separation, and the presence of charge and/or surface-passivation defects. Our results suggest that rapid exciton transfer from “bright” nanocrystals to surface trap states in nearest-neighbors can efficiently fill such traps and enhance the stability of emission by promoting the radiative recombination of slowly diffusing excited electrons.« less

Marra, J.C.

1996-10-01

Exposure to lead can lead to adverse health affects including permanent damage to the central nervous system. Common means of exposure to lead are from ingestion of lead paint chips or breathing of dust from deteriorating painted surfaces. The U.S. Army has over 101 million square feet of buildings dating to World War II or earlier. Many of these structures were built before the 1978 ban on lead based paints. The U.S. Army Corps of Engineers CERL is developing technologies to remove and stabilize lead containing organic coatings. Promising results have been achieved using a patented flame spray process thatmore » utilizes a glass frit to stabilize the hazardous constituents. When the glass frit is sprayed onto the paint containing substrate, differences in thermal expansion coefficients between the frit and the paint results in spalling of the paint from the substrate surface. The removed fragments are then collected and remelted to stabilize the hazardous constituents and allow for disposal as non-hazardous waste. Similar successful results using a patented process involving microwave technology for paint removal have also been achieved. In this process, the painted surface is coated with a microwave coupling compound that when exposed to microwave energy results in the spalling of the hazardous paint from the surface. The fragments can again be accumulated and remelted for stabilization and disposal.« less

Design of cost-effective electrocatalysts with enhanced stability and activity is of paramount importance for the next generation of energy conversion systems, including fuel cells and electrolyzers. However, electrocatalytic materials generally improve one of these properties at the expense of the other. Here, using Density Functional Theory calculations and electrochemical surface science measurements, we explore atomic-level features of ultrathin (hydroxy)oxide films on transition metal substrates and demonstrate that these films exhibit both excellent stability and activity for electrocatalytic applications. The films adopt structures with stabilities that significantly exceed bulk Pourbaix limits, including stoichiometries not found in bulk and properties that aremore » tunable by controlling voltage, film composition, and substrate identity. Using nickel (hydroxy)oxide/Pt(111) as an example, we further show how the films enhance activity for hydrogen evolution through a bifunctional effect.

Japan consists of 3900 islands and lies off the east coast of Asia. Even though Japan is one of the most densely populated nations in the world, its growth rate has stabilized at .5%. 94% of all children go to senior high school and almost 90% finish. Responsibility for the sick, aged, and infirmed is changing from the family and private sector to government. Japan was founded in 600 BC and its 1st capital was in Nara (710-1867). The Portuguese, the 1st Westerners to make contact with Japan in 1542, opened trade which lasted until the mid 17th century. US Navy Commodore Matthew Perry forced Japan to reopen in 1854. Following wars with China and Russia in the late 1800s and early 1900s respectively, Japan took part in World Wars I and II. In between these wars Japan invaded Manchuria and China. The US dropped an atomic bomb on Hiroshima and Nagasaki and the Japanese surrendered in September, 1945 ending World War II (WWII). Following, WWII, the Allied Powers guided Japan's establishment as a nonthreatening nation and a democratic parliamentary government (a constitutional monarchy) with a limited defense force. Japan remains one of the most politically stable of all postwar democracies. The Liberal Democratic Party's Noboru Takeshita became prime minister in 1987. Japan has limited natural resources and only 19% of the land is arable. Japanese ingenuity and skill combine to produce one of the highest per hectare crop yields in the world. Japan is a major economic power, and its and the US economies are becoming more interdependent. Its exports, making up only 13% of the gross national product, mainly go to Canada and the US. Many in the US are concerned, however, with the trade deficit with Japan and are seeking ways to make trade more equitable. Japan wishes to maintain good relations with its Asian neighbors and other nations. The US and Japan enjoy a strong, productive relationship.

Posttraumatic Growth and Dyadic Adjustment among War Veterans and their Wives

Lahav, Yael; Kanat-Maymon, Yaniv; Solomon, Zahava

2017-01-01

The controversy regarding the nature of posttraumatic growth includes two main competing claims: one which argues that posttraumatic growth reflects authentic positive changes and the other which argues that posttraumatic growth reflects illusory defenses. While the former might suggest that posttraumatic growth enhances intimacy and close relationships, the latter might imply that posttraumatic growth hinders interpersonal relations. The present study aimed to test these claims by investigating the association between posttraumatic growth and dyadic adjustment over time at both the individual and dyadic levels, and the potential role of posttraumatic stress symptoms. Former prisoners of war and comparable war veterans and their wives (n = 229) were assessed twice, 30–31 (T1) and 35–38 (T2) years after the 1973 Yom Kippur War in Israel, with regard to posttraumatic growth, posttraumatic stress symptoms and dyadic adjustment. Results indicated that posttraumatic growth was associated with both elevated posttraumatic stress symptoms and low dyadic adjustment among both husbands and wives. Posttraumatic stress symptoms at T1 and T2 mediated the association between posttraumatic growth and dyadic adjustment. Wives' posttraumatic growth at T1 predicted posttraumatic growth and dyadic adjustment of the husbands at T2. The higher the wives' posttraumatic growth, the higher the posttraumatic growth and the lower the dyadic adjustment of the husbands in the subsequent measure. The findings suggest that posttraumatic growth reflects defensive beliefs which undermine marital relationships and that posttraumatic growth might be transmitted between spouses and implicated in the deterioration of the marital relationship over time.

Distal hereditary motor neuropathy is a heterogeneous group of inherited neuropathies characterized by distal limb muscle weakness and atrophy. Although at least 15 genes have been implicated in distal hereditary motor neuropathy, the genetic causes remain elusive in many families. To identify an additional causal gene for distal hereditary motor neuropathy, we performed exome sequencing for two affected individuals and two unaffected members in a Taiwanese family with an autosomal dominant distal hereditary motor neuropathy in which mutations in common distal hereditary motor neuropathy-implicated genes had been excluded. The exome sequencing revealed a heterozygous mutation, c.770A > G (p.His257Arg), in the cytoplasmic tryptophanyl-tRNA synthetase (TrpRS) gene (WARS) that co-segregates with the neuropathy in the family. Further analyses of WARS in an additional 79 Taiwanese pedigrees with inherited neuropathies and 163 index cases from Australian, European, and Korean distal hereditary motor neuropathy families identified the same mutation in another Taiwanese distal hereditary motor neuropathy pedigree with different ancestries and one additional Belgian distal hereditary motor neuropathy family of Caucasian origin. Cell transfection studies demonstrated a dominant-negative effect of the p.His257Arg mutation on aminoacylation activity of TrpRS, which subsequently compromised protein synthesis and reduced cell viability. His257Arg TrpRS also inhibited neurite outgrowth and led to neurite degeneration in the neuronal cell lines and rat motor neurons. Further in vitro analyses showed that the WARS mutation could potentiate the angiostatic activities of TrpRS by enhancing its interaction with vascular endothelial-cadherin. Taken together, these findings establish WARS as a gene whose mutations may cause distal hereditary motor neuropathy and alter canonical and non-canonical functions of TrpRS. © The Author (2017).

Damping Goes the Distance in Golf

2004-01-01

In the late 1980s, Dr. Benjamin Dolgin of NASA s Jet Propulsion Laboratory developed a concept for a high-damping graphite/viscoelastic material for the Strategic Defense Initiative (popularly referred to as "Star Wars"), as part of a space-based laser anti-missile program called "Asterix." Dolgin drummed up this concept with the intention of stabilizing weapons launch platforms in space, where there is no solid ground to firmly support these structures. Without the inclusion of high-damping material, the orbital platforms were said to vibrate for 20 minutes after force was applied - a rate deemed "unacceptable" by leaders of the Strategic Defense Initiative.

War experiences and psychotic symptoms among former child soldiers in Northern Uganda: the mediating role of post-war hardships – the WAYS Study

Psychotic symptoms have been associated with post-traumatic stress disorder and war experiences. However, the relationships between types of war experiences, the onset and course of psychotic symptoms, and post-war hardships in child soldiers have not been investigated. This study assessed whether various types of war experiences contribute to psychotic symptoms differently and whether post-war hardships mediated the relationship between war experiences and later psychotic symptoms. In an ongoing longitudinal cohort study (the War-Affected Youths Survey), 539 (61% male) former child soldiers were assessed for psychotic symptoms, post-war hardships, and previous war experiences. Regression analyses were used to assess the contribution of different types of war experiences on psychotic symptoms and the mediating role of post-war hardships in the relations between previous war experiences and psychotic symptoms. The findings yielded ‘witnessing violence’, ‘deaths and bereavement’, ‘involvement in hostilities’, and ‘sexual abuse’ as types of war experiences that significantly and independently predict psychotic symptoms. Exposure to war experiences was related to psychotic symptoms through post-war hardships (β = .18, 95% confidence interval = [0.10, 0.25]) accounting for 50% of the variance in their relationship. The direct relation between previous war experiences and psychotic symptoms attenuated but remained significant (β = .18, 95% confidence interval = [0.12, 0.26]). Types of war experiences should be considered when evaluating risks for psychotic symptoms in the course of providing emergency humanitarian services in post-conflict settings. Interventions should consider post-war hardships as key determinants of psychotic symptoms among war-affected youths. PMID:24718435

Does it matter how I perceive my nation? National symbols, national identification and attitudes toward immigrants.

We examined how the ways of imagining one's own nation relate to the relationship between national identification and individuals' attitudes towards immigrants. National imagination is studied through two types of national symbols representing the nation in terms of confrontation between groups (i.e., war and sports) and a unique entity (i.e., nature and traditional culture). We found that national identification was positively associated with the degree to which individuals perceived their nation through a historical war and sports, which, in turn, enhanced negative attitudes toward immigrants. Unexpectedly, the degree to which individuals perceived their nation through nature and traditional culture was positively associated with positive intergroup attitudes. The results emphasize that the degree to which individuals perceive their nation through different national symbols is an important factor for understanding intergroup relations. © 2013 The Scandinavian Psychological Associations.

The 2006 Lebanon War exposed children in the north of Israel to daily rocket attacks. To cope with the massive psychological needs, a teacher-delivered protocol focusing on enhancing personal resilience was implemented. Children were assessed for risk factors, symptoms, and adaptation before the 16-week program (Time 1; n = 983) and after its completion (Time 2; n = 563). At a 3-month follow-up (Time 3; n = 754) children were assessed together with a waiting-list comparison group (n = 1,152). Participating children showed a significant symptom decrease at Time 2 and significantly fewer symptoms than the control group at Time 3. Six or more risk factors were associated with greater symptoms and parental concern about the child's adaptive functioning. Teachers are valuable cost-effective providers for clinically informed interventions after mass trauma and disaster. Copyright © 2011 International Society for Traumatic Stress Studies.

C-5 Propynyl Modifications Enhance the Mechanical Stability of DNA.

Increased thermal or mechanical stability of DNA duplexes is desired for many applications in nanotechnology or -medicine where DNA is used as a programmable building block. Modifications of pyrimidine bases are known to enhance thermal stability and have the advantage of standard base-pairing and easy integration during chemical DNA synthesis. Through single-molecule force spectroscopy experiments with atomic force microscopy and the molecular force assay we investigated the effect of pyrimidines harboring C-5 propynyl modifications on the mechanical stability of double-stranded DNA. Utilizing these complementary techniques, we show that propynyl bases significantly increase the mechanical stability if the DNA is annealed at high temperature. In contrast, modified DNA complexes formed at room temperature and short incubation times display the same stability as non-modified DNA duplexes. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Improved image reconstruction of low-resolution multichannel phase contrast angiography

Abstract. In low-resolution phase contrast magnetic resonance angiography, the maximum intensity projected channel images will be blurred with consequent loss of vascular details. The channel images are enhanced using a stabilized deblurring filter, applied to each channel prior to combining the individual channel images. The stabilized deblurring is obtained by the addition of a nonlocal regularization term to the reverse heat equation, referred to as nonlocally stabilized reverse diffusion filter. Unlike reverse diffusion filter, which is highly unstable and blows up noise, nonlocal stabilization enhances intensity projected parallel images uniformly. Application to multichannel vessel enhancement is illustrated using both volunteer data and simulated multichannel angiograms. Robustness of the filter applied to volunteer datasets is shown using statistically validated improvement in flow quantification. Improved performance in terms of preserving vascular structures and phased array reconstruction in both simulated and real data is demonstrated using structureness measure and contrast ratio.

Commercial coolants such as water, ethylene glycol and triethylene glycol possess very low thermal conductivity, high vapor pressure, corrosion issues and low thermal stability thus limiting the thermal enhancement of the nanofluids. Thus, a new type of base fluid known as deep eutectic solvents (DESs) is proposed in this work as a potential substitute for the conventional base fluid due to their unique solvent properties such as low vapor pressure, high thermal stability, biodegradability and non-flammability. In this work, 33 different DESs derived from phosphonium halide salt and ammonium halide salts were synthesised. Carbon nantubes (CNTs) with different concentrations (0.01 wt%-0.08 wt%) were dispersed into DESs with the help of sonication. Stability of the nanofluids were determined using both qualitative (visual observation) and quantitative (UV spectroscopy) approach. In addition, thermo-physical properties such as thermal conductivity, specific heat, viscosity and density were investigated. The stability results indicated that phosphonium based DESs have higher stability (up to 4 d) as compared to ammonium-based DESs (up to 3 d). Thermal enhancement of 30% was observed for ammonium based DES-CNT nanofluid whereas negative thermal enhancement was observed in phosphonium based DES-CNT nanofluid.

Past research revealed war trauma and posttraumatic stress disorder (PTSD) symptoms as potential predictors for domestic and community violence in crisis regions and among soldiers in different armed conflicts. The impact of family violence and other adversities experienced in childhood as well as of a combat-enhanced appeal for aggressive behavior (appetitive aggression) remains to be specified. In the present study, the authors separately predicted violence against children, intimate partner violence and community violence in 381 Burundian soldiers returning from foreign deployment and living in a post- conflict region. Using path analysis, they aimed to disentangle the independent contributions and pathways of the following variables: Exposure to war trauma and childhood familial violence, PTSD and depression symptom severity, and appetitive aggression. Childhood familial violence had an independent effect on all contexts of violence and was the only significant predictor for violence against the soldiers' own children. Intimate partner violence was additionally predicted by depression symptom severity, while community violence was additionally predicted by PTSD symptom severity and appetitive aggression. Besides war-related mental ill-health and appetitive aggression, violent experiences during childhood development must not be overlooked as a factor fueling the cycle of violence in conflict regions.

An assessment of survey measures used across key epidemiologic studies of United States Gulf War I Era Veterans

PubMed Central

2013-01-01

Over the past two decades, 12 large epidemiologic studies and 2 registries have focused on U.S. veterans of the 1990–1991 Gulf War Era. We conducted a review of these studies’ research tools to identify existing gaps and overlaps of efforts to date, and to advance development of the next generation of Gulf War Era survey tools. Overall, we found that many of the studies used similar instruments. Questions regarding exposures were more similar across studies than other domains, while neurocognitive and psychological tools were the most variable. Many studies focused on self-reported survey results, with a range of validation practices. However, physical exams, biomedical assessments, and specimen storage were not common. This review suggests that while research may be able to pool data from past surveys, future surveys need to consider how their design can yield data comparable with previous surveys. Additionally, data that incorporate recent technologies in specimen and genetic analyses would greatly enhance such survey data. When combined with existing data on deployment-related exposures and post-deployment health conditions, longitudinal follow-up of existing studies within this collaborative framework could represent an important step toward improving the health of veterans.

The study examines, first, the effectiveness of a psychosocial intervention based on Teaching Recovery Techniques (TRT) to increase resiliency among Palestinian children, exposed to a major trauma of war. Second, it analyses the role of family factors (maternal attachment and family atmosphere) as moderating the intervention impacts on resilience. School classes in Gaza were randomized into intervention (N=242) and control (N=240) groups. The percentage of girls (49.4%) and boys (50.6%) were equal, and the child age was 10-13 years in both groups. Children reported positive indicators of their mental health (prosocial behaviour and psychosocial well-being) at baseline (T1), post-intervention (T2) and at a six-month follow-up (T3). At T1 they accounted their exposure to war trauma. Mothers reported about their willingness to serve as an attachment figure, and the child reported about the family atmosphere. Resilience was conceptualized as a presence of positive indications of mental health despite trauma exposure. Against our hypothesis, the intervention did not increase the level of resilience statistically significantly, nor was the effect of the intervention moderated by maternal attachment responses or family atmosphere.

Assessing the Impact of Electrostatic Drag on Processive Molecular Motor Transport.

PubMed

Smith, J Darby; McKinley, Scott A

2018-06-04

The bidirectional movement of intracellular cargo is usually described as a tug-of-war among opposite-directed families of molecular motors. While tug-of-war models have enjoyed some success, recent evidence suggests underlying motor interactions are more complex than previously understood. For example, these tug-of-war models fail to predict the counterintuitive phenomenon that inhibiting one family of motors can decrease the functionality of opposite-directed transport. In this paper, we use a stochastic differential equations modeling framework to explore one proposed physical mechanism, called microtubule tethering, that could play a role in this "co-dependence" among antagonistic motors. This hypothesis includes the possibility of a trade-off: weakly bound trailing molecular motors can serve as tethers for cargoes and processing motors, thereby enhancing motor-cargo run lengths along microtubules; however, this introduces a cost of processing at a lower mean velocity. By computing the small- and large-time mean-squared displacement of our theoretical model and comparing our results to experimental observations of dynein and its "helper protein" dynactin, we find some supporting evidence for microtubule tethering interactions. We extrapolate these findings to predict how dynein-dynactin might interact with the opposite-directed kinesin motors and introduce a criterion for when the trade-off is beneficial in simple systems.

A room temperature strategy towards enhanced performance and bias stability of oxide thin film transistor with a sandwich structure channel layer

Thermal annealing is a conventional and effective way to improve the bias stress stability of oxide thin film transistors (TFT) on solid substrates. However, it is still a challenge for enhancing the bias stress stability of oxide TFTs on flexible substrates by high-temperature post-treatment due to the thermal sensitivity of flexible substrates. Here, a room temperature strategy is presented towards enhanced performance and bias stability of oxide TFTs by intentionally engineering a sandwich structure channel layer consisting of a superlattice with aluminum doped zinc oxide (AZO) and Al2O3 thin films. The Al2O3/AZO/Al2O3-TFTs not only exhibit a saturation mobility of 9.27 cm2 V-1 s-1 and a linear mobility of 11.38 cm2 V-1 s-1 but also demonstrate a better bias stress stability than AZO/Al2O3-TFT. Moreover, the underlying mechanism of this enhanced electrical performance of TFTs with a sandwich structure channel layer is that the bottom Al2O3 thin films can obviously improve the crystalline phase of AZO films while decreasing electrical trapping centers and adsorption sites for undesirable molecules such as water and oxygen.

Increasing numbers of materials have been extensively used as platforms for enzyme immobilization to enhance catalytic activity and stability. Although stability of enzyme was accomplished with immobilization approaches, activity of the most of the enzymes was declined after immobilization. Herein, we synthesize the flower shaped-hybrid nanomaterials called hybrid nanoflower (HNF) consisting of urease enzyme and copper ions (Cu(2+)) and report a mechanistic elucidation of enhancement in both activity and stability of the HNF. We demonstrated how experimental factors influence morphology of the HNF. We proved that the HNF (synthesized from 0.02mgmL(-1) urease in 10mM PBS (pH 7.4) at +4°C) exhibited the highest catalytic activity of ∼2000% and ∼4000% when stored at +4°C and RT, respectively compared to free urease. The highest stability was also achieved by this HNF by maintaining 96.3% and 90.28% of its initial activity within storage of 30 days at +4°C and RT, respectively. This dramatically enhanced activity is attributed to high surface area, nanoscale-entrapped urease and favorable urease conformation of the HNF. The exceptional catalytic activity and stability properties of HNF can be taken advantage of to use it in fields of biomedicine and chemistry. Copyright © 2015 Elsevier Inc. All rights reserved.

For U.S. neo-idealists, the 1990s represented a moment to be seized, a time in which the strategies of conflict and confrontation of the Cold War period could be replaced by strategies designed to enhance cooperation among the nation-states. In 2001, the George W. Bush administration found itself in the position of continuing the same Bill Clinton…

It is shown that smoke from fires started by nuclear explosions could continue to cause significant disruption even after it has fallen from the atmosphere, by lowering the reflectivity of snow and sea ice surfaces, with possible effects on climate in northern latitudes caused by enhanced absorption of sunlight. The reduced reflectivity could persist for several years on Arctic sea ice and on the ablation area of the Greenland ice sheet.

Coming home from prison: Adapting military resilience training to enhance successful community reintegration for justice-involved Iraq-Afghanistan veterans.

PubMed

2018-05-01

We propose a veteran-centric justice model of resilience training developed by the military for assisting service members coming home from war and modify it to assist Iraq/Afghanistan veterans coming home from prison. Incarceration has been identified as a stress aftereffect of the prolonged Iraq and Afghanistan combat deployments. Notably, the rate of Iraq and Afghanistan-era incarcerated veterans increased from 4% to 13% between 2004 and 2012 for all incarcerated veterans. Successful reentry to the community from prison incarceration is difficult, with rearrest and reincarceration a frequent occurrence. Moreover, combat stress conditions may weaken the justice-involved Iraq/Afghanistan's veteran's ability to face challenges posed by the return home from prison. As in the war zone, the return home from prison may be idealized with unrealistic expectations and/or goals, thus setting up the returning veteran for disappointment, anger, deepening of alienation and disconnection from larger civilian society, and the risk of return to maladaptive mechanisms for coping. Resilience training can be provided in psychoeducational venues prior to prison release and with follow-up postrelease. Resilience building offers promise as an intervention to enhance the justice-involved veteran's successful community reentry. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Confined Rayleigh-Bénard, Rotating Rayleigh-Bénard, and Double Diffusive Convection: A Unifying View on Turbulent Transport Enhancement through Coherent Structure Manipulation

Many natural and engineering systems are simultaneously subjected to a driving force and a stabilizing force. The interplay between the two forces, especially for highly nonlinear systems such as fluid flow, often results in surprising features. Here we reveal such features in three different types of Rayleigh-Bénard (RB) convection, i.e., buoyancy-driven flow with the fluid density being affected by a scalar field. In the three cases different stabilizing forces are considered, namely (i) horizontal confinement, (ii) rotation around a vertical axis, and (iii) a second stabilizing scalar field. Despite the very different nature of the stabilizing forces and the corresponding equations of motion, at moderate strength we counterintuitively but consistently observe an enhancement in the flux, even though the flow motion is weaker than the original RB flow. The flux enhancement occurs in an intermediate regime in which the stabilizing force is strong enough to alter the flow structures in the bulk to a more organized morphology, yet not too strong to severely suppress the flow motions. Near the optimal transport enhancements all three systems exhibit a transition from a state in which the thermal boundary layer (BL) is nested inside the momentum BL to the one with the thermal BL being thicker than the momentum BL. The observed optimal transport enhancement is explained through an optimal coupling between the suction of hot or fresh fluid and the corresponding scalar fluctuations.

In many countries veterans from World War II are growing old. Research has shown that war experiences continue to impact those who have been involved in war for a long time. The present study targets old injured war veterans from World War II in Finland. The aim of this study was to produce knowledge of the impact of war experiences and injuries on the lifespan of Finnish war veterans. The method used was grounded theory. Data were collected by interviewing 20 aged war veterans in their homes. The analysis resulted in four categories, with also subcategories: (1) lost childhood and youth; (2) war traumas impacting life; (3) starting life from scratch; and (4) finding one's own place. A substantive theory of war veterans' lifelong struggle for freedom throughout the lifespan was outlined. The war overshadowed the whole lifespan of the veterans, but in old age they finally felt free. Since war experiences vary depending on historical context, a formal theory would require additional research.

Exposure to war-related experiences can comprise a broad variety of experiences and the very nature of certain war-related events has generally been neglected. To examine the long-term outcomes of war-related death of family members, the authors investigated the prevalence rates of major depressive episode (MDE), anxiety disorders, and quality of life among civilian war survivors with or without war-related death of first-degree family members 9 years after the war in Kosovo. Compared to participants without war-related death of family members, those who had experienced such loss had signficantly higher prevalence rates of MDE, posttraumatic stress disorder, and generalized anxiety disorder, and reported a lower quality of life 9 years after the war. These results indicate that bereaved civilian survivors of war experience significant mental health problems many years after the war.

Enzyme stability is an important issue for protein engineers. Understanding how rigidity in the active site affects protein kinetic stability will provide new insight into enzyme stabilization. In this study, we demonstrated enhanced kinetic stability of Candida antarctica lipase B (CalB) by mutating the structurally flexible residues within the active site. Six residues within 10 Å of the catalytic Ser(105) residue with a high B factor were selected for iterative saturation mutagenesis. After screening 2200 colonies, we obtained the D223G/L278M mutant, which exhibited a 13-fold increase in half-life at 48 °C and a 12 °C higher T50(15), the temperature at which enzyme activity is reduced to 50% after a 15-min heat treatment. Further characterization showed that global unfolding resistance against both thermal and chemical denaturation also improved. Analysis of the crystal structures of wild-type CalB and the D223G/L278M mutant revealed that the latter formed an extra main chain hydrogen bond network with seven structurally coupled residues within the flexible α10 helix that are primarily involved in forming the active site. Further investigation of the relative B factor profile and molecular dynamics simulation confirmed that the enhanced rigidity decreased fluctuation of the active site residues at high temperature. These results indicate that enhancing the rigidity of the flexible segment within the active site may provide an efficient method for improving enzyme kinetic stability.

Nanolipoprotein particles (NLPs) consist of a discoidal phospholipid lipid bilayer confined by an apolipoprotein belt. NLPs are a promising platform for a variety of biomedical applications due to their biocompatibility, size, definable composition, and amphipathic characteristics. However, poor serum stability hampers the use of NLPs for in vivo applications such as drug formulation. In this study, NLP stability was enhanced upon the incorporation and subsequent UV-mediated intermolecular cross-linking of photoactive DiynePC phospholipids in the lipid bilayer, forming cross-linked nanoparticles (X-NLPs). Both the concentration of DiynePC in the bilayer and UV exposure time significantly affected the resulting X-NLP stability in 100%more » serum, as assessed by size exclusion chromatography (SEC) of fluorescently labeled particles.

A new 'normal' in global affairs may be erupting from large global powers to that of non-state actors and proxies committing violence through scaled conflict in a post-Westphalian world generating significant global health policy challenges. Health security of populations are multifactorial and indirectly proportional to war, conflict and disaster. Preventing conflict and avoiding the health vacuum that occurs in war and violence may be best practices for policy makers. This paper considers an approach of applying clinical primary prevention principles to global health policy. Brief policy review of current standards and practices in health security in fragile and failed states and prevention; and definitions discussion. A short case study series are presented with best practices, with risk and outcome review. The global balance of power and order may be shifting through geopolitical transference and inadequate action by major global power brokers. Health security in at risk nation-states may be decreasing as a result. Small scale conflict with large-scale violence threatens health security and may experience increased incidence and prevalence in fragile and failed states. Preventative policy to resuscitate fragile and failed states and prevent further external and internal shocks may support health and promote a positive feedback loop of further state stability and increased health security. Public health policy shift to mitigate state failure and public health crisis in war and conflict through the basis of primary prevention may provide best practices and maximize health security for at risk populations.

Corporate interests, philanthropies, and the peace movement.

Corporate and philanthropic involvement in the peace movement is growing. In considering medical peace groups as examples, we have studied the ways that corporate and philanthropic funding have shaped the course of activism. Our methods have included: review of the Foundations Grant Index from 1974-1983; analysis of corporations' and foundations' criteria for grants in the categories of peace, arms control, and disarmament; interviews with leaders of activist organizations and with foundation officials; and our own experiences in the peace movement. Corporate interests in preventing nuclear war stem from a concern for global stability in which world markets may expand, and from a hope to frame issues posed by the peace movement in a way that will not challenge basic structures of power and finance. Several general features make peace groups respectable and attractive to philanthropies; an uncritical stance toward corporate participation in the arms race; a viewpoint that the main danger of nuclear war stems from a profound, bilateral conflict between the United States and the Soviet Union; and a single-issue focus that does not deal with the many related problems reflecting the injustices of capitalism. The two major medical groups working for peace, Physicians for Social Responsibility (PSR) and International Physicians for the Prevention of Nuclear War (IPPNW), have accomplished many goals; however, their adherence to subtle criteria of respectability and their dependence on philanthropic funding have limited the scope of their activism. The struggle for peace can not succeed without fundamental changes in the corporate system that initiates, maintains, and promotes the arms race.

2017-03-01

Lactobacillus plantarum has been known be able to produce uricase for uric acid biosensor. Durability and stability of L. plantarum in generating uricase enzyme was low. Hence, we tried to enhance its durability and stability by immobilizing it onto activated 250 mg zeolite at room temperature using 100 μL L.plantarum suspension and 2.87 mM uric acid, while Michaelis-Menten constant (KM) and Vmax were obtained at 6.7431 mM and 0.9171 µA consecutively, and the linearity range was 0.1-3.3 mM (R2 = 0.9667). Limit of detection (LOD) and limit of quantification (LOQ) value of the measurement were 0.4827 mM and 1.6092 mM respectively. Biosensor stability treatment was carried out in two different treatments, using the same electrode and using disposable electrode. The disposable electrode stability showed better result based on repeated measurements, but stability was still need improvement.

Biopolyester-based systems containing naturally occurring compounds with enhanced thermo-oxidative stability.

This work presents a sustainable approach for the stabilization of polylactic acid (PLA) against thermo-oxidative aging. Naturally occurring phenolic and polyphenolic compounds, such as ferulic acid (FerAc), vanillic acid (VanAc), quercetin (Querc) and vitamin E (VitE), were introduced into PLA. The preliminary characterization of the systems formulated containing different amounts of natural stabilizers showed that all compounds used acted as plasticizers, leading to a decrease in rheological functions with respect to neat PLA, without significantly modifying the crystallinity of the raw material. The study of the thermo-oxidative behavior of neat PLA and PLA/natural compound systems, performed by spectrometric and thermal analyses, indicated that all stabilizers considered were able to exert a remarkable antioxidant action against thermo-oxidative phenomena. All natural compounds considered are thus proposed as ecofriendly stabilizers, to get fully bio-based polymer systems with enhanced thermo-oxidative stability, suitable for biomedical applications.

Enhanced superconductivity of fullerenes

Methods for enhancing characteristics of superconductive fullerenes and devices incorporating the fullerenes are disclosed. Enhancements can include increase in the critical transition temperature at a constant magnetic field; the existence of a superconducting hysteresis over a changing magnetic field; a decrease in the stabilizing magnetic field required for the onset of superconductivity; and/or an increase in the stability of superconductivity over a large magnetic field. The enhancements can be brought about by transmitting electromagnetic radiation to the superconductive fullerene such that the electromagnetic radiation impinges on the fullerene with an energy that is greater than the band gap of the fullerene.

2016-10-01

An organic–inorganic halide CH 3NH 3SnI 3 perovskite with significantly improved structural stability is obtained via pressure-induced amorphization and recrystallization. In situ high-pressure resistance measurements reveal an increased electrical conductivity by 300% in the pressure-treated perovskite. Photocurrent measurements also reveal a substantial enhancement in visible-light responsiveness. In conclusion, the mechanism underlying the enhanced properties is shown to be associated with the pressure-induced structural modification.

Enhanced stability of monomer fold correlates with extreme drug resistance of HIV-1 protease.

2013-10-29

During treatment, mutations in HIV-1 protease (PR) are selected rapidly that confer resistance by decreasing affinity to clinical protease inhibitors (PIs). As these unique drug resistance mutations can compromise the fitness of the virus to replicate, mutations that restore conformational stability and activity while retaining drug resistance are selected on further evolution. Here we identify several compensating mechanisms by which an extreme drug-resistant mutant bearing 20 mutations (PR20) with >5-fold increased Kd and >4000-fold decreased affinity to the PI darunavir functions. (1) PR20 cleaves, albeit poorly, Gag polyprotein substrates essential for viral maturation. (2) PR20 dimer, which exhibits distinctly enhanced thermal stability, has highly attenuated autoproteolysis, thus likely prolonging its lifetime in vivo. (3) The enhanced stability of PR20 results from stabilization of the monomer fold. Both monomeric PR20(T26A) and dimeric PR20 exhibit Tm values 6-7.5 °C higher than those for their PR counterparts. Two specific mutations in PR20, L33F and L63P at sites of autoproteolysis, increase the Tm of monomeric PR(T26A) by ~8 °C, similar to PR20(T26A). However, without other compensatory mutations as seen in PR20, L33F and L63P substitutions, together, neither restrict autoproteolysis nor significantly reduce binding affinity to darunavir. To determine whether dimer stability contributes to binding affinity for inhibitors, we examined single-chain dimers of PR and PR(D25N) in which the corresponding identical monomer units were covalently linked by GGSSG sequence. Linking of the subunits did not appreciably change the ΔTm on inhibitor binding; thus stabilization by tethering appears to have little direct effect on enhancing inhibitor affinity.

Effects of dual tasks and dual-task training on postural stability: a systematic review and meta-analysis

The use of dual-task training paradigm to enhance postural stability in patients with balance impairments is an emerging area of interest. The differential effects of dual tasks and dual-task training on postural stability still remain unclear. A systematic review and meta-analysis were conducted to analyze the effects of dual task and training application on static and dynamic postural stability among various population groups. Systematic identification of published literature was performed adhering to Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, from inception until June 2016, on the online databases Scopus, PEDro, MEDLINE, EMBASE, and SportDiscus. Experimental studies analyzing the effects of dual task and dual-task training on postural stability were extracted, critically appraised using PEDro scale, and then summarized according to modified PEDro level of evidence. Of 1,284 records, 42 studies involving 1,480 participants met the review’s inclusion criteria. Of the studies evaluating the effects of dual-task training on postural stability, 87.5% of the studies reported significant enhancements, whereas 30% of the studies evaluating acute effects of dual tasks on posture reported significant enhancements, 50% reported significant decrements, and 20% reported no effects. Meta-analysis of the pooled studies revealed moderate but significant enhancements of dual-task training in elderly participants (95% CI: 1.16–2.10) and in patients suffering from chronic stroke (−0.22 to 0.86). The adverse effects of complexity of dual tasks on postural stability were also revealed among patients with multiple sclerosis (−0.74 to 0.05). The review also discusses the significance of verbalization in a dual-task setting for increasing cognitive–motor interference. Clinical implications are discussed with respect to practical applications in rehabilitation settings. PMID:28356727

Although the rapid development of organic-inorganic metal halide perovskite solar cells has led to certified power conversion efficiencies of above 20%, their poor stability remains a major challenge, preventing their practical commercialization. In this paper, we investigate the intrinsic origin of the poor stability in perovskite solar cells by using a confocal fluorescence microscope. We find that the degradation of perovskite films starts from grain boundaries and gradually extend to the center of the grains. Firmly based on our findings, we further demonstrate that the device stability can be significantly enhanced by increasing the grain size of perovskite crystals. Our results have important implications to further enhance the stability of optoelectronic devices based on metal halide perovskites.

Enhancement of Peroxidase Stability Against Oxidative Self-Inactivation by Co-immobilization with a Redox-Active Protein in Mesoporous Silicon and Silica Microparticles

The study of the stability enhancement of a peroxidase immobilized onto mesoporous silicon/silica microparticles is presented. Peroxidases tend to get inactivated in the presence of hydrogen peroxide, their essential co-substrate, following an auto-inactivation mechanism. In order to minimize this inactivation, a second protein was co-immobilized to act as an electron acceptor and thus increase the stability against self-oxidation of peroxidase. Two heme proteins were immobilized into the microparticles: a fungal commercial peroxidase and cytochrome c from equine heart. Two types of biocatalysts were prepared: one with only covalently immobilized peroxidase (one-protein system) and another based on covalent co-immobilization of peroxidase and cytochrome c (two-protein system), both immobilized by using carbodiimide chemistry. The amount of immobilized protein was estimated spectrophotometrically, and the characterization of the biocatalyst support matrix was performed using Brunauer-Emmett-Teller (BET), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX), and Fourier transform infrared (FTIR) analyses. Stability studies show that co-immobilization with the two-protein system enhances the oxidative stability of peroxidase almost four times with respect to the one-protein system. Thermal stability analysis shows that the immobilization of peroxidase in derivatized porous silicon microparticles does not protect the protein from thermal denaturation, whereas biogenic silica microparticles confer significant thermal stabilization.

To predict the ecological consequences of biodiversity loss, researchers have spent much time and effort quantifying how biological variation affects the magnitude and stability of ecological processes that underlie the functioning of ecosystems. Here we add to this work by looking at how biodiversity jointly impacts two aspects of ecosystem functioning at once: (1) the production of biomass at any single point in time (biomass/area or biomass/ volume), and (2) the stability of biomass production through time (the CV of changes in total community biomass through time). While it is often assumed that biodiversity simultaneously enhances both of these aspects of ecosystem functioning, the joint distribution of data describing how species richness regulates productivity and stability has yet to be quantified. Furthermore, analyses have yet to examine how diversity effects on production covary with diversity effects on stability. To overcome these two gaps, we reanalyzed the data from 34 experiments that have manipulated the richness of terrestrial plants or aquatic algae and measured how this aspect of biodiversity affects community biomass at multiple time points. Our reanalysis confirms that biodiversity does indeed simultaneously enhance both the production and stability of biomass in experimental systems, and this is broadly true for terrestrial and aquatic primary producers. However, the strength of diversity effects on biomass production is independent of diversity effects on temporal stability. The independence of effect sizes leads to two important conclusions. First, while it may be generally true that biodiversity enhances both productivity and stability, it is also true that the highest levels of productivity in a diverse community are not associated with the highest levels of stability. Thus, on average, diversity does not maximize the various aspects of ecosystem functioning we might wish to achieve in conservation and management. Second, knowing how biodiversity affects productivity gives no information about how diversity affects stability (or vice versa). Therefore, to predict the ecological changes that occur in ecosystems after extinction, we will need to develop separate mechanistic models for each independent aspect of ecosystem functioning.

The association between attachment and mental health symptoms in adolescents in a post-conflict low resource setting has not been documented. We investigated the relationship between parent and peer attachment and posttraumatic stress, depression and anxiety symptoms in a sample of 551 adolescents aged 13-21 years old. Attachment quality was assessed using the Inventory of Parent and Peer Attachment (IPPA). Post-traumatic stress, depression and anxiety symptoms were assessed using the Impact of Events Scale Revised (IESR) and Hopkins Symptom Checklist for Adolescents (HSCL-37A) respectively. Gender differences in attachment relationships were determined using independent t-tests. Multivariate logistic regression was used to assess whether attachment relationships were independently associated with posttraumatic stress, depression and anxiety symptoms. Hierarchical linear regression analyses were conducted to explore the moderating role of war-related trauma. Our analyses revealed gender differences in attachment to parents, with males reporting stronger attachment than females. Parental attachment was protective against depression and anxiety symptoms but not posttraumatic stress symptoms after adjusting for potential confounders. Alienation by parents was independently associated with an increase in these mental health symptoms while peer attachment was not associated with any of these symptoms. However, in situations of severe trauma, our analyses showed that peer attachment was significantly protective against post-traumatic stress symptoms. Secure parental attachment is associated with better psychosocial adjustment in adolescents affected by war. Further, adolescents with secure peer attachment relationships in situations of severe war trauma may be less likely to develop posttraumatic stress symptoms. Interventions to enhance peer support in this post conflict setting would benefit this vulnerable population.

While the current knowledge base on the mental health effects of displacement is mainly limited to refugees residing in industrialised countries, this paper examines the impact of war-induced displacement and related risk factors on the mental health of Eastern Congolese adolescents, and compares currently internally displaced adolescents to returnees and non-displaced peers. Data were collected from a community sample of 819 adolescents aged 13 to 21 years, attending one of 10 selected schools across the Ituri district in the Democratic Republic of Congo. Respondents completed culturally adapted self-report measures of posttraumatic stress symptoms (using the Impact of Event Scale - Revised) and internalising and externalising behaviour problems (by means of the Hopkins Symptoms Checklist - 37 for Adolescents). Associated factors studied were age, sex, parental death, exposure to war-related violence and daily stressors. Internally displaced persons (IDPs) reported highest mean scores for the IES-R and the HSCL-37A internalising scale, followed by returnees, while non-displaced adolescents scored significantly lower. However, ANCOVA tests showed that posttraumatic stress and internalising symptoms were mainly associated with traumatic exposure and daily stressors and not with displacement status. Externalising problem scores were associated with traumatic exposure, daily stressors and displacement. Remarkably, death of father was associated with fewer externalising problems. Sex was differently associated with internalising and externalising problems through traumatic and daily stressors. As IDPs are highly exposed to violence and daily stressors, they report most psychological distress, when compared to returnees and non-displaced peers. The distinct mental health outcomes for returned youngsters illustrate how enhancing current socio-economic living conditions of war-affected adolescents could stimulate resilient outcomes, despite former trauma or displacement.

Climatic Consequences of Nuclear Conflict

A nuclear war between Russia and the United States could still produce nuclear winter, even using the reduced arsenals of about 4000 total nuclear weapons that will result by 2017 in response to the New START treaty. A nuclear war between India and Pakistan, with each country using 50 Hiroshima-sized atom bombs as airbursts on urban areas, could produce climate change unprecedented in recorded human history. This scenario, using much less than 1% of the explosive power of the current global nuclear arsenal, would produce so much smoke from the resulting fires that it would plunge the planet to temperatures colder than those of the Little Ice Age of the 16th to 19th centuries, shortening the growing season around the world and threatening the global food supply. Crop model studies of agriculture in the U.S. and China show massive crop losses, even for this regional nuclear war scenario. Furthermore, there would be massive ozone depletion with enhanced ultraviolet radiation reaching the surface. These surprising conclusions are the result of recent research (see URL) by a team of scientists including those who produced the pioneering work on nuclear winter in the 1980s, using the NASA GISS ModelE and NCAR WACCM GCMs. The soot is self-lofted into the stratosphere, and the effects of regional and global nuclear war would last for more than a decade, much longer than previously thought. Nuclear proliferation continues, with nine nuclear states now, and more working to develop or acquire nuclear weapons. The continued environmental threat of the use of even a small number of nuclear weapons must be considered in nuclear policy deliberations in Russia, the U.S., and the rest of the world.

International oil trade is a subset of global trade and there exist oil trade communities. These communities evolve over time and provide clues of international oil trade patterns. A better understanding of the international oil trade patterns is necessary for governments in policy making. To study the evolution of trade communities in the international oil trade network, we set up unweighted and weighted oil trade network models based on complex network theory using data from 2002 to 2011. We detected the communities in the oil trade networks and analyzed their evolutionary properties and stabilities over time. We found that the unweighted and weighted international oil trade networks show many different features in terms of community number, community scale, distribution of countries, quality of partitions, and stability of communities. Two turning points occurred in the evolution of community stability in the international oil trade network. One is the year 2004-2005 which correlates with changes in demand and supply in the world oil market after the Iraq War, and the other is the year 2008-2009 which is connected to the 2008 financial crisis. Different causations of instability show different features and this should be considered by policy makers.

Is crisis stability still achievable?

NASA Astrophysics Data System (ADS)

Pollack, Joshua

During the Cold War, the idea of crisis stability concerned whether the United States and the Soviet Union would be faced with powerful incentives to strike each other first with their nuclear weapons during periods of tension. This idea influenced the design of nuclear forces and guided aspects of nuclear arms control. The United States and Russia continue to operate large, alert nuclear forces, but at least three new factors have emerged that add significantly greater complexity to this picture. The first new factor consists of the development and deployment of new strategic military technologies that are entangled with nuclear weapons. These include strategic ballistic missile defenses, counter-space weapons, and strategic conventional weapons. The second new factor consists of new dyads of interacting strategic forces beyond US-Russia. These include US-China, US-North Korea, India-Pakistan, and India-China. The third new factor consists of the emergence of three-actor crisis stability dynamics, where the third actor is not necessarily nuclear-armed. This paper illustrates the concept with the US-North Korea-South Korea triangle. It briefly discusses the implications of these developments and reflects on the broad policy options that may be available.

Video stabilization is an important video enhancement technology which aims at removing annoying shaky motion from videos. We propose a practical and robust approach of video stabilization that produces full-frame stabilized videos with good visual quality. While most previous methods end up with producing smaller size stabilized videos, our completion method can produce full-frame videos by naturally filling in missing image parts by locally aligning image data of neighboring frames. To achieve this, motion inpainting is proposed to enforce spatial and temporal consistency of the completion in both static and dynamic image areas. In addition, image quality in the stabilized video is enhanced with a new practical deblurring algorithm. Instead of estimating point spread functions, our method transfers and interpolates sharper image pixels of neighboring frames to increase the sharpness of the frame. The proposed video completion and deblurring methods enabled us to develop a complete video stabilizer which can naturally keep the original image quality in the stabilized videos. The effectiveness of our method is confirmed by extensive experiments over a wide variety of videos.

Medical Effects of a Transuranic "Dirty Bomb".

PubMed

Durakovic, Asaf

2017-03-01

The modern military battlefields are characterized by the use of nonconventional weapons such as encountered in the conflicts of the Gulf War I and Gulf War II. Recent warfare in Iraq, Afghanistan, and the Balkans has introduced radioactive weapons to the modern war zone scenarios. This presents the military medicine with a new area of radioactive warfare with the potential large scale contamination of military and civilian targets with the variety of radioactive isotopes further enhanced by the clandestine use of radioactive materials in the terrorist radioactive warfare. Radioactive dispersal devices (RDDs), including the "dirty bomb," involve the use of organotropic radioisotopes such as iodine 131, cesium 137, strontium 90, and transuranic elements. Some of the current studies of RDDs involve large-scale medical effects, social and economic disruption of the society, logistics of casualty management, cleanup, and transportation preparedness, still insufficiently addressed by the environmental and mass casualty medicine. The consequences of a dirty bomb, particularly in the terrorist use in urban areas, are a subject of international studies of multiple agencies involved in the management of disaster medicine. The long-term somatic and genetic impact of some from among over 400 radioisotopes released in the nuclear fission include somatic and transgenerational genetic effects with the potential challenges of the genomic stability of the biosphere. The global contamination is additionally heightened by the presence of transuranic elements in the modern warzone, including depleted uranium recently found to contain plutonium 239, possibly the most dangerous substance known to man with one pound of plutonium capable of causing 8 billion cancers. The planning for the consequences of radioactive dirty bomb are being currently studied in reference to the alkaline earths, osteotropic, and stem cell hazards of internally deposited radioactive isotopes, in particular uranium and transuranic elements. The spread of radioactive materials in the area of the impact would expose both military and civilian personnel to the blast and dust with both inhalational, somatic, and gastrointestinal exposure, in the aftermath of the deployment of RDDs. The quantities of radioactive materials have proliferated from the original quantity of plutonium first isolated in 1941 from 0.5 mg to the current tens of thousands of kilograms in the strategic nuclear arsenal with the obvious potential consequences to the biosphere and mankind. In an event of RDD employment, the immediate goal of disaster and mass casualty medicine would be a synchronized effort to contain the scope of the event, followed by cleanup and treatment procedures. A pragmatic approach to this problem is not always possible because of unpredictability of the terrorist-use scenarios. Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.

The effect of nanoparticle aggregation on surfactant foam stability.

PubMed

AlYousef, Zuhair A; Almobarky, Mohammed A; Schechter, David S

2018-02-01

The combination of nanoparticles (NPs) and surfactant may offer a novel technique of generating stronger foams for gas mobility control. This study evaluates the potential of silica NPs to enhance the foam stability of three nonionic surfactants. Results showed that the concentration of surfactant and NPs is a crucial parameter for foam stability and that there is certain concentrations for strong foam generation. A balance in concentration between the nonionic surfactants and the NPs can enhance the foam stability as a result of forming flocs in solutions. At fixed surfactant concentration, the addition of NPs at low to intermediate concentrations can produce a more stable foam compared to the surfactant. The production of small population of flocs as a result of mixing the surfactant and NPs can enhance the foam stability by providing a barrier between the gas bubbles and delaying the coalescence of bubbles. Moreover, these flocs can increase the solution viscosity and, therefore, slow the drainage rate of thin aqueous film (lamellae). The measurements of foam half-life, bubble size, and mobility tests confirmed this conclusion. However, the addition of more solid particles or surfactant might have a negative impact on foam stability and reduce the maximum capillary pressure of coalescence as a result of forming extensive aggregates.

Thermal stability is important for the manufacture, distribution and administration of vaccines, especially in tropical developing countries, where particularly adverse field conditions exist. Current live-attenuated flavivirus vaccines exhibit relatively poor liquid stability in clinical settings, and clinicians are instructed to discard the yellow fever vaccine 1h after reconstitution. We have identified novel combinations of excipients that greatly enhance the thermal stability of live-attenuated DEN-2 PDK-53-based flavivirus vaccine candidates. Liquid formulations comprising a sugar, albumin and a pluronic polymer minimized the loss of flavivirus infectious titer to less than 0.5log(10)pfu after storage for at least 8h at 37°C, 7 days at room temperature or at least 11 weeks at 4°C. Additionally, these formulations prevented reduction of viral infectivity after two freeze-thaw cycles of virus. Formulated candidate vaccines were readily lyophilized and reconstituted with minimal loss of viral titers. In mice, the formulations were safe and did not hinder the ability of the vaccine virus to generate a potent, protective immune response. These formulations provided significantly greater liquid-phase stability than has been reported previously for other flavivirus vaccine formulations. The enhanced thermal stability provided by the formulations described here will facilitate the effective distribution of flavivirus vaccines worldwide. PMID:21803103

In this study of current and former male Reserve and National Guard members from the State of Ohio, it was expected that veterans who were older, had more years of military service, who had participated in the Persian Gulf War, who were Euro-Americans, who were higher in rank, who had higher residential stability in Ohio, who belonged to the Air Force, who had higher formal education, and who belonged to the National Guard would have a greater investment in U.S. society as defined by 11 demographic variables. It was assumed that those with greater investment in society would more often have valid addresses and would be more likely to respond to a survey on military issues, thereby biasing sample outcomes in those directions. Results for male veterans were consistent with the hypothesis that investment in the society system would predict validity of addresses and response rates. In other words, results supported the idea that those veterans who might be expected to have a greater investment in U.S. society were more likely to be located and to respond (once located) to a survey concerning Desert Storm-era military service and its aftermath. Implications for future Desert Storm research are discussed.

In this retrospective study, 18 patients with war injuries of the shoulder were reviewed to evaluate the technical problems associated with external fixation and to analyze the incidence of infection and late functional results. The average patient age was 28.5 years. All patients were male. Thirteen patients had explosive wounds, whereas five wounds were caused by gunshot missiles. All injuries were extensive in terms of bone and soft tissue defects. Six patients presented with complex injuries involving neurovascular structures. Sixteen patients were treated with external fixation. Application of the proximal pins of the external fixator through the humeral head was possible in eight patients, the scapula served as the site of proximal fixation in four patients, only the clavicle was available for placement of pins in two patients, and both the scapula and the clavicle had to be pinned to achieve proximal stabilization in two patients. In two patients, fixation was not possible and early amputation was performed. Infection was eventually eradicated in all patients, allowing for adequate soft tissue coverage of the wounds. Analysis of functional results at an average of 6 years after the injury showed a considerable degree of functional deficit in most patients.

Exosomes, the extracellular secretary nano-vesicles, act as carriers of biomolecules to the target cells. They exhibit several attributes of an efficient drug delivery system. Curcumin, despite having numerous bioactive and therapeutic properties, has limited pharmaceutical use due to its poor water solubility, stability, and low systemic bioavailability. Hence, this study aims to enhance the therapeutic potential of curcumin, a model hydrophobic drug, by its encapsulation into milk exosomes. In the present study, we investigated the stability of free curcumin and exosomal curcumin in PBS and in vitro digestive processes. Additionally, their uptake and trans-epithelial transport were studied on Caco-2 cells. Curcumin in milk exosomes had higher stability in PBS, sustained harsh digestive processes, and crossed the intestinal barrier than free curcumin. In conclusion, the encapsulation of curcumin into the exosomes enhances its stability, solubility, and bioavailability. Therefore, the present study demonstrated that milk exosomes act as stable oral drug delivery vehicles.

Bacterial lipopolysaccharide binding enhances virion stability and promotes environmental fitness of an enteric virus

Summary Enteric viruses, including poliovirus and reovirus, encounter a vast microbial community in the mammalian gastrointestinal tract, which has been shown to promote virus replication and pathogenesis. Investigating the underlying mechanisms, we find that poliovirus binds bacterial surface polysaccharides, which enhances virion stability and cell attachment by increasing binding to the viral receptor. Additionally, we identified a poliovirus mutant, VP1-T99K, with reduced lipopolysaccharide (LPS) binding. Although T99K and WT poliovirus cell attachment, replication and pathogenesis in mice are equivalent, following peroral inoculation of mice, VP1-T99K poliovirus was unstable in feces. Consequently, the ratio of mutant virus in feces is reduced following additional cycles of infection in mice. Thus, the mutant virus incurs a fitness cost when environmental stability is a factor. These data suggest that poliovirus binds bacterial surface polysaccharides, enhancing cell attachment and environmental stability, potentially promoting transmission to a new host. PMID:24439896

To investigate the influence of the war on perinatal and maternal mortality during the war conflict in Bosnia and Herzegovina. In a retrospective study we analysed perinatal and maternal mortality in the pre-war period (1988-1991), the war period (1992-1995) and the post-war period (1996-2003). We also analysed the number of deliveries, the perinatal and maternal mortality rates and their causes. During the analysed period we had a range of 3337-6912 deliveries per year, with a decreased number in the war period. During the war period and immediately after the war, the perinatal mortality rate increased to 20.9-26.3% (average 24.28%). After the war the rate decreased to 8.01% in 2003 (p < 0.05). Maternal mortality before the war was 39/100,000 deliveries, during the war it increased to 65/100,000 and after the war it decreased to 12/100,000 deliveries (p < 0.05). The increase in maternal mortality during the war was because of an increased number of uterine ruptures, sepsis and bleeding due to shell injury of pregnant women. During the war we could expect a decreased number of deliveries, and an increased rate of perinatal and maternal mortality and preterm deliveries due to: inadequate nutrition, stress factors (life in refugee's centers, bombing, deaths of relatives, uncertain future...), and break down of the perinatal care system (lack of medical staff, impossibility of collecting valid health records, particularly perinatal information, and the destruction of medical buildings).

Plans for and early feasibility investigations into the modification of a Lockheed D21B drone to flight test the DRACO Rocket Based Combined Cycle (RBCC) engine are discussed. Modifications include the addition of oxidizer tanks, modern avionics systems, actuators, and a vehicle recovery system. Current study results indicate that the D21B is a suitable candidate for this application and will allow demonstrations of all DRACO engine operating modes at Mach numbers between 0.8 and 4.0. Higher Mach numbers may be achieved with more extensive modification. Possible project risks include low speed stability and control, and recovery techniques.

The first railway station in Żary was built in 1843 in Germany. After the Second World War and years of socialism in Poland the meaning of railway decreased and its technical condition deteriorated. Now the building needs renovation and change of function. Tensegrity structures may be useful in renovation of platforms shelter. They are strut and tie construction, in which there is self-stabilization between compressed and tensioned elements. Conception of new platform shelter is based on exemplary tensegrity module consist of three struts and nine cables (called "Simplex"). Tensegrity would make railway station more modern, but not cover its original elevation.

How can the stability of a state be quantitatively determined and its future stability predicted? The rise and collapse of empires and states is very complex, and it is exceedingly difficult to understand and predict it. Existing theories are usually formulated as verbal models and, consequently, do not yield sharply defined, quantitative prediction that can be unambiguously validated with data. Here we describe a model that determines whether the state is in a stable or chaotic condition and predicts its future condition. The central model, which we test, is that growth and collapse of states is reflected by the changes of their territories, populations and budgets. The model was simulated within the historical societies of the Roman Empire (400 BC to 400 AD) and the European Union (1957-2007) by using wavelets and analysis of the sign change of the spectrum of Lyapunov exponents. The model matches well with the historical events. During wars and crises, the state becomes unstable; this is reflected in the wavelet analysis by a significant increase in the frequency ω (t) and wavelet coefficients W (ω, t) and the sign of the largest Lyapunov exponent becomes positive, indicating chaos. We successfully reconstructed and forecasted time series in the Roman Empire and the European Union by applying artificial neural network. The proposed model helps to quantitatively determine and forecast the stability of a state.

The authenticity of the engine performance and controller enabled the development of realistic enhanced control modes through controller modification alone. Use of enhanced control modes improved stability and control of an impaired aircraft. - Fast Response is useful for manual manipulation of the throttles - Use of Fast Response improved stability as part of a yaw rate feedback system. - Use of Overthrust shortened takeoff distance, but was generally useful in flight, too. Initial lack of pilot familiarity resulted in discomfort, especially with yaw rate feedback, but that was the only drawback, overall the pilot found the enhanced modes very helpful.

The purpose of this study was to examine the effectiveness and specificity of a classroom-based psychosocial intervention after war. All students (n=2500) of six villages in Southern Lebanon designated as most heavily exposed to war received a classroom-based intervention delivered by teachers, consisting of cognitive-behavioural and stress inoculation training strategies. A random sample of treated students (n=101) and a matched control group (n=93) were assessed one month post-war and one year later. Mental disorders and psychosocial stressors were assessed using the Diagnostic Interview for Children and Adolescents - Revised with children and parents. War exposure was measured using the War Events Questionnaire. The prevalence of major depressive disorder (MDD), separation anxiety disorder (SAD) and post-traumatic stress disorder (PTSD) was examined pre-war, one month post-war (pre-intervention), and one year post-war. Specificity of treatment was determined by rating teachers' therapy diaries. The rates of disorders peaked one month post-war and decreased over one year. There was no significant effect of the intervention on the rates of MDD, SAD or PTSD. Post-war MDD, SAD and PTSD were associated with pre-war SAD and PTSD, family violence parameters, financial problems and witnessing war events. These findings have significant policy and public health implications, given current practices of delivering universal interventions immediately post-war.

The transfer-free fabrication of the high quality graphene on the metallic nanostructures, which is highly desirable for device applications, remains a challenge. Here, we develop the transfer-free method by direct chemical vapor deposition of the graphene layers on copper (Cu) nanoparticles (NPs) to realize the hybrid nanostructures. The graphene as-grown on the Cu NPs permits full electric contact and strong interactions, which results in a strong localization of the field at the graphene/copper interface. An enhanced intensity of the localized surface plasmon resonances (LSPRs) supported by the hybrid nanostructures can be obtained, which induces a much enhanced fluorescent intensity from the dye coated hybrid nanostructures. Moreover, the graphene sheets covering completely and uniformly on the Cu NPs act as a passivation layer to protect the underlying metal surface from air oxidation. As a result, the stability of the LSPRs for the hybrid nanostructures is much enhanced compared to that of the bare Cu NPs. The transfer-free hybrid nanostructures with enhanced intensity and stability of the LSPRs will enable their much broader applications in photonics and optoelectronics. PMID:27872494

We determined cause-specific mortality prevalence and risks of Gulf War deployed and nondeployed veterans to determine if deployed veterans were at greater risk than nondeployed veterans for death overall or because of certain diseases or conditions up to 13 years after conflict subsided. Follow-up began when the veteran left the Gulf War theater or May 1, 1991, and ended on the date of death or December 31, 2004. We studied 621   901 veterans who served in the 1990-1991 Persian Gulf War and 746   247 veterans who served but were not deployed during the Gulf War. We used Cox proportional hazard models to calculate rate ratios adjusted for age at entry to follow-up, length of follow-up, race, sex, branch of service, and military unit. We compared the mortality of (1) Gulf War veterans with non-Gulf War veterans and (2) Gulf War army veterans potentially exposed to nerve agents at Khamisiyah in March 1991 with those not exposed. We compared standardized mortality ratios of deployed and nondeployed Gulf War veterans with the US population. Male Gulf War veterans had a lower risk of mortality than male non-Gulf War veterans (adjusted rate ratio [aRR] = 0.97; 95% confidence interval [CI], 0.95-0.99), and female Gulf War veterans had a higher risk of mortality than female non-Gulf War veterans (aRR = 1.15; 95% CI, 1.03-1.28). Khamisiyah-exposed Gulf War army veterans had >3 times the risk of mortality from cirrhosis of the liver than nonexposed army Gulf War veterans (aRR = 3.73; 95% CI, 1.64-8.48). Compared with the US population, female Gulf War veterans had a 60% higher risk of suicide and male Gulf War veterans had a lower risk of suicide (standardized mortality ratio = 0.84; 95% CI, 0.80-0.88). The vital status and mortality risk of Gulf War and non-Gulf War veterans should continue to be investigated.

Objectives To determine how many veterans in a random sample of British veterans who served in the Gulf war believe they have “Gulf war syndrome,” to examine factors associated with the presence of this belief, and to compare the health status of those who believe they have Gulf war syndrome with those who do not. Design Questionnaire study asking British Gulf war veterans whether they believe they have Gulf war syndrome and about symptoms, fatigue, psychological distress, post-traumatic stress, physical functioning, and their perception of health. Participants 2961 respondents to questionnaires sent out to a random sample of 4250 Gulf war veterans (69.7%). Main outcome measure The proportion of veterans who believe they have Gulf war syndrome. Results Overall, 17.3% (95% confidence interval 15.9 to 18.7) of the respondents believed they had Gulf war syndrome. The belief was associated with the veteran having poor health, not serving in the army when responding to the questionnaire, and having received a high number of vaccinations before deployment to the Gulf. The strongest association was knowing another person who also thought they had Gulf war syndrome. Conclusions Substantial numbers of British Gulf war veterans believe they have Gulf war syndrome, which is associated with psychological distress, a high number of symptoms, and some reduction in activity levels. A combination of biological, psychological, and sociological factors are associated with the belief, and these factors should be addressed in clinical practice. What is already known on this topicThe term Gulf war syndrome has been used to describe illnesses and symptoms experienced by veterans of the 1991 Gulf warConcerns exist over the validity of Gulf war syndrome as a unique entityWhat this study adds17% of Gulf war veterans believe they have Gulf war syndromeHolding the belief is associated with worse health outcomesKnowing someone else who believes they have Gulf war syndrome and receiving more vaccinations were associated with holding the belief PMID:11532836

Armed conflict imposes huge hardship on young people living in war zones. This study assessed former child soldiers' experience and perception of stress in common war events during the armed conflict in northern Uganda and compares it with their non-recruited counterparts. To investigate whether child soldiers experienced more severe exposure to war events, and explore how war might affect youths differently, depending on the co-occurrence of these events. The study was undertaken in four northern Ugandan districts in 22 secondary schools with a sample size of 981 youths, about half of whom had been child soldiers. The participants completed a questionnaire on socio-demographic characteristics and stressful war events which was analyzed using descriptive statistics, a probabilistic index and correlation network analysis. Former child soldiers had significantly greater experience of war events than their non-recruited counterparts. The violence of war is more central in their experience and perception of stress, whereas the scarcity of resources and poor living conditions are most central for non-recruited participants. The extent to which a war event, such as separation from the family, is perceived as stressful depends on the experience and perception of other stressful war events, such as confrontation with war violence for former child soldiers and life in an Internally Displaced Persons' camp for non-recruited participants. The network approach permitted demonstration of the many ways in which war-affected youths encounter and appraise stressful war events. War events might function as moderators or mediators of the effect that other war events exert on the lives and well-being of young people living in war zones. This demands comprehensive and individualized assessment.

Active war in Sri Lanka: Children's war exposure, coping, and posttraumatic stress disorder symptom severity.

2016-01-01

Posttraumatic stress disorder (PTSD) in response to active war is understudied among Sinhalese children in Sri Lanka. We investigated PTSD symptom severity in children using child (n = 60) and mother (n = 60) reports; child-reported war exposure and coping; as well as self-reported maternal PTSD symptom severity. The study addressed active war in 2 rural locations (acute and chronic community war exposure). Child-reports were significantly greater than mother-reports of child PTSD symptom severity. Furthermore, children's war exposure, child-reported and mother-reported child PTSD symptom severity, and maternal PTSD symptom severity were significantly greater in the acute versus chronic community war exposure location, but children's approach and avoidance coping did not significantly differ, indicating a potential ceiling effect. Children's war exposure significantly, positively predicted child-reported child PTSD symptom severity, controlling for age, gender, and maternal PTSD symptom severity, but only maternal PTSD symptom severity significantly, positively predicted mother-reported child PTSD symptom severity. Avoidance coping (in both acute and chronic war) significantly positively mediated the children's war exposure-child-reported child PTSD symptom severity relation, but not mother-reports of the same. Approach coping (in chronic but not acute war) significantly, positively mediated the children's war exposure-child-reported and mother-reported child PTSD symptom severity relations. We advanced the literature on long-term active war by confirming the value of children's self-reports, establishing that both approach and avoidance coping positively mediated the war-exposure-PTSD symptom severity relation, and that the mediation effect of approach coping was situationally moderated by acute verses chronic community war exposure among Sri Lankan children.

[The war at home: "war amenorrhea" in the First World War].

PubMed

Stukenbrock, Karin

2008-01-01

In 1917, the Göttingen gynaecologist Dietrich published a short article about a phenomenon which he called "war amenorrhea" ("Kriegsamenorrhoe"). The article attracted the attention of his colleagues. While the affected women did not pay much attention to their amenorrhea, the physicians considered the phenomenon a new disease which was mainly caused by the war. This new disease gave the gynaecologists the opportunity to present their specialty as a discipline with high relevance for medicine in times of war. Nevertheless, there was no consensus about the importance, the incidence, the diagnostic criteria, the causes and the appropriate therapy of"war amenorrhea". Although the gynaecologists failed to define a uniform clinical syndrome, they maintained the construction of "war amenorrhea" after the war and subsumed it under well known types of amenorrhea. We can conclude that under the conditions of war a new disease emerged which was not sharply defined.

Trajectories of attachment in older age: interpersonal trauma and its consequences.

Bachem, Rahel; Levin, Yafit; Solomon, Zahava

Previous studies suggest that attachment insecurities may increase after trauma exposure, an effect documented only at a group level. This study explores the heterogeneity of changes over time and examines the associations of the nature of the traumatic event (interpersonal and nonpersonal), and its consequences (posttraumatic stress disorder [PTSD] and loneliness) with attachment trajectories. Two groups of Israeli veterans participated: 164 former prisoners-of-war and 185 combat veterans. Attachment was assessed at four points (1991-2015). Risk factors were evaluated in 1991. Using latent growth mixture modeling, trajectories of attachment insecurities were explored. Three avoidance trajectories (stability, decrease, inverse u-shaped) and two anxiety trajectories (stability, decrease) were identified. The inverse u-shaped avoidance trajectory was associated with captivity, humiliation, loneliness, and PTSD, and stable avoidance was associated with loneliness. Stable anxiety was associated with captivity and loneliness. Attachment insecurities can change during aging and persist decades after a trauma. Trauma-related risk factors are related to more deleterious trajectories.

Uganda--rehabilitation, or redefinition of health services?

PubMed

Dodge, C P

1986-01-01

Uganda had one of the best health care delivery systems in Africa. The decade of misrule by Amin saw a collapse of the country and an exodus of doctors and other professions. The 1979 liberation war and subsequent political instability and insecurity further aggravated the poor health services then available. When political stability was temporarily restored in December 1980 the cash crop export sector took priority over social services and the health budget declined to only 3.5% compared to a former level of 7.5% of government budget. Emergencies in West Nile, Karamoja and the Luwero triangle continued to plague rehabilitation efforts upto 1985. Alternate strategies for improving health are proposed including female education, increased budget allocations, food and nutrition policy and health information. Uganda's prospect for rebuilding the health services has begun with immunization, control of diarrhoeal diseases, nutrition surveillance in Karamoja and an essential drugs programme, but the success of these is dependent upon political stability and improvement in overall security.

Enhanced electrical stability of flexible indium tin oxide films prepared on stripe SiO 2 buffer layer-coated polymer substrates by magnetron sputtering

The electrical stability of flexible indium tin oxide (ITO) films fabricated on stripe SiO 2 buffer layer-coated polyethylene terephthalate (PET) substrates by magnetron sputtering was investigated by the bending test. The ITO thin films with stripe SiO 2 buffer layer under bending have better electrical stability than those with flat SiO 2 buffer layer and without buffer layer. Especially in inward bending text, the ITO thin films with stripe SiO 2 buffer layer only have a slight resistance change when the bending radius r is not less than 8 mm, while the resistances of the films with flat SiO 2 buffer layer and without buffer layer increase significantly at r = 16 mm with decreasing bending radius. This improvement of electrical stability in bending test is due to the small mismatch factor α in ITO-SiO 2, the enhanced interface adhesion and the balance of residual stress. These results indicate that the stripe SiO 2 buffer layer is suited to enhance the electrical stability of flexible ITO film under bending.

Plasma Density Effects on Toroidal Flow Stabilization of Edge Localized Modes

Cheng, Shikui; Zhu, Ping; Banerjee, Debabrata

2016-10-01

Recent EAST experiments have demonstrated mitigation and suppression of edge localized modes (ELMs) with toroidal rotation flow in higher collisionality regime, suggesting potential roles of plasma density. In this work, the effects of plasma density on the toroidal flow stabilization of the high- n edge localized modes have been extensively studied in linear calculations for a circular-shaped limiter H-mode tokamak, using the initial-value extended MHD code NIMROD. In the single MHD model, toroidal flow has a weak stabilizing effects on the high- n modes. Such a stabilization, however, can be significantly enhanced with the increase in plasma density. Furthermore, our calculations show that the enhanced stabilization of high- n modes from toroidal flow with higher edge plasma density persists in the 2-fluid MHD model. These findings may explain the ELM mitigation and suppression by toroidal rotation in higher collisionality regime due to the enhancement of plasma density obtained in EAST experiment.

An organic-inorganic halide CH 3 NH 3 SnI 3 perovskite with significantly improved structural stability is obtained via pressure-induced amorphization and recrystallization. In situ high-pressure resistance measurements reveal an increased electrical conductivity by 300% in the pressure-treated perovskite. Photocurrent measurements also reveal a substantial enhancement in visible-light responsiveness. The mechanism underlying the enhanced properties is shown to be associated with the pressure-induced structural modification. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

British Muslims and the UK government's 'war on terror' within: evidence of a clash of civilizations or emergent de-civilizing processes?

PubMed

Vertigans, Stephen

2010-03-01

In the immediate aftermath of the September 2001 attacks on America, defending civilization was quickly established at the core of the 'war on terror'. Unintentionally or otherwise this incorporation of civilization connected with Samuel Huntington's 'Clash of Civilizations' thesis. Within the 'war on terror' the dark side of counterterrorism has become apparent through international practices like extrajudicial killing, extraordinary rendition and torture. The impact of Western governments' policies upon their indigenous Muslim populations has also been problematic but social and political analysis has been relatively limited. This paper seeks to help address the scarcity of sociological contributions. Hidden costs of the UK government's attempts to utilize violence and enhance social constraints within the nation-state are identified. It is argued that although counterterrorism strategies are contributing to a self-fulfilling spiral of hatred that could be considered evidence in support of the 'Clash of Civilizations', the thesis is unhelpful when trying to grasp the underlying processes. Instead the paper draws upon Norbert Elias's application of the concepts of 'civilizing' and 'de-civilizing' to help improve levels of understanding about the processes and consequences of particular Muslim communities being targeted by security forces. The paper concludes with an exploration of the majority of the population's acquiescence and willingness to accept restraints upon Muslims in order to safeguard their own security.

Phosphate amendments, especially phosphate rock (PR), are one of the most commonly used materials to stabilize heavy metals in contaminated soils. However, most of PR reserve consists of low-grade ore, which limits the efficiency of PR for stabilizing heavy metals. This study was to enhance the stabilization of heavy metals through improving the available phosphorous (P) release of PR by oxalic acid activation. Raw PR and activated PR (APR) were characterized by scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), X-ray powder diffraction (XRD), Brunauer-Emmett-Teller (BET) surface analysis, and laser diffraction to determine the changes of structure and composition of APR. The stabilization effectiveness of lead (Pb), zinc (Zn), and cadmium (Cd) in soils by APR was investigated through toxicity leaching test and speciation analysis. The results indicated that after treatment by oxalic acid, (1) the crystallinity of the fluorapatite phase of PR transformed into the weddellite phase; (2) the surface area of PR increased by 37%; (3) the particle size of PR became homogenized (20-70 μm); and (4) the available P content in PR increased by 22 times. These changes of physicochemical characteristics of PR induced that APR was more effective to transform soil heavy metals from the non-residual fraction to the residual fraction and enhance the stabilization efficiency of Pb, Zn, and Cd than PR. These results are significant for the future use of low-grade PR to stabilize heavy metals.

Chitosan based atorvastatin nanocrystals: effect of cationic charge on particle size, formulation stability, and in-vivo efficacy

Cationic charged chitosan as stabilizer was evaluated in preparation of nanocrystals using probe sonication method. The influence of cationic charge densities of chitosan (low CSL, medium CSM, high CSH molecular weights) and Labrasol® in solubility enhancement and modifying the release was investigated, using atorvastatin (ATR) as poorly soluble model drug. Compared to CSM and CSH; low cationic charge of CSL acted as both electrostatic and steric stabilizer by significant size reduction to 394 nm with charge of 21.5 meV. Solubility of ATR-CSL increased to 60-fold relative to pure ATR and ATR-L. Nanocrystals were characterized for physiochemical properties. Scanning electron microscopy revealed scaffold-like structures with high surface area. X-ray powder diffractometry and differential scanning calorimetry revealed crystalline to slight amorphous state changes after cationic charge size reduction. Fourier transform-infrared spectra indicated no potent drug-excipient interactions. The enhanced dissolution profile of ATR-CSL indicates that sustained release was achieved compared with ATR-L and Lipitor®. Anti-hyperlipidemic performance was pH dependent where ATR-CSL exhibited 2.5-fold higher efficacy at pH 5 compared to pH 6 and Lipitor®. Stability studies indicated marked changes in size and charge for ATR-L compared to ATR-CSL exemplifying importance of the stabilizer. Therefore, nanocrystals developed with CSL as a stabilizer is a promising choice to enhance dissolution, stability, and in-vivo efficacy of major Biopharmaceutical Classification System II/IV drugs.

Enhanced Product Stability in the Hammerhead Ribozyme†

PubMed Central

Shepotinovskaya, Irina; Uhlenbeck, Olke C.

2010-01-01

The rate of dissociation of P1, the 5′ product of hammerhead cleavage, is 100–300-fold slower in full-length hammerheads than in hammerheads that either lack or have disrupting mutations in the loop-loop tertiary interaction. The added stability requires the presence of residue 17 at the 3′ terminus of P1 but not the 2′, 3′ terminal phosphate. Since residue 17 is buried within the catalytic core of the hammerhead in the x-ray structure, we propose that the enhanced P1 stability is the result of the cooperative folding of the hammerhead around this residue. However, since the P1 is fully stabilized above 2.5 mM MgCl2 while hammerhead activity continues to increase with increasing MgCl2, it is clear that the hammerhead structure in the transition state must differ from that of the product complex. The product stabilization assay is used to test our earlier proposal that different tertiary interactions modulate the cleavage rate by differentially stabilizing the core. PMID:20423112

These modified oxidized cellulose nanocrystals (m-O-CNCs) were homogeneous/electrostatically stable in water and they can stabilize O/W Pickering emulsions. The dispersed phase volume fraction (DPVF) of the Pickering emulsion was 0.7 at around 1.5g/L, whereas the tween-20 control needed a 13-fold greater concentration to have a similar DPVR. In addition, these m-O-CNC stabilized Pickering emulsions also showed good mechanical and thermal stability against centrifugation and heat, as well as size controllability. In terms of stability, size controllability, surfactant-free status, these m-O-CNCs possess superior and enhanced emulsifying properties. Future research for these new interfacial materials have potential in applications, for personal care, cosmetic and pharmaceutic industries. Copyright © 2017 Elsevier Ltd. All rights reserved.

We tested the hypothesis that intergenerational effects of parents' war trauma on offspring's attachment and mental health are mediated by psychological maltreatment. Two hundred and forty children and their parents were sampled from a war-prone area, Gaza, Palestine. The parents reported the number and type of traumatic experiences of war they had had during their lifetime before the child's birth and during a current war when the child was 10-12 years old. The children reported their war traumas, experiences of psychological maltreatment, attachment security, and symptoms of posttraumatic stress (PTSS), depression, and aggression. The direct and indirect intergenerational effects of war trauma were tested in structural equation models. The hypotheses were confirmed for father's past war exposure, and disconfirmed for mother's war exposure. The father's past war trauma had a negative association with attachment security and positive association with the child's mental health problems mediated by increased psychological maltreatment. In contrast, the mother's past war trauma had a negative association with the child's depression via decreased psychological maltreatment. The mother's current war trauma had a negative association with the child's depression and aggression via decreased psychological maltreatment. Among fathers, past war exposure should be considered as a risk factor for psychological maltreatment of children and the associated attachment insecurity and mental health problems. Among mothers, war exposure as such could be given less clinical attention than PTSS in the prevention of psychological maltreatment of children. Copyright © 2013 Elsevier Ltd. All rights reserved.

Baseline holder (BLH) circuits are used widely to stabilize the analog output of application-specific integrated circuits (ASICs) for high-count-rate applications. The careful design of BLH circuits is vital to the overall stability of the analog-signal-processing chain in ASICs. Recently, we observed self-triggered fluctuations in an ASIC in which the shaping circuits have a BLH circuit in the feedback loop. In fact, further investigations showed that methods of enhancing small-signal stabilities cause an even worse situation. To resolve this problem, we used large-signal analyses to study the circuit’s stability. We found that a relatively small gain for the error amplifier and a small current in the non-linear stage of the BLH are required to enhance stability in large-signal analysis, which will compromise the properties of the BLH. These findings were verified by SPICE simulations. In this paper, we present our detailed analysis of the BLH circuits, and propose an improved version of them that have only minimal self-triggered fluctuations. We summarize the design considerations both for the stability and the properties of the BLH circuits. PMID:27182081

Z-scheme Ag3PO4/POM/GO heterojunction with enhanced photocatalytic performance for degradation and water splitting.

2018-05-01

To develop solar light-driven photocatalysts with high activity and structural stability, Ag3PO4/POM/GO heterojunction has been successfully prepared by a facile method at room temperature. Ag3PO4/POM/GO shows remarkably enhanced activity and stability for photocatalytic degradation and H2 production from water-splitting under simulated solar light. The degradation rate of Ag3PO4/POM/GO is 1.8 times and 1.2 times those of Ag3PO4 and Ag3PO4/POMs, respectively. H2 production using Ag3PO4/POM/GO is 2.0 times that of Ag3PO4/GO. The enhanced photocatalytic performance of Ag3PO4/POM/GO is attributed to the increased surface area, electronegativity and structure stability. The Z-scheme system of Ag3PO4/POM/GO effectively promotes charge separation, resulting in enhanced photocatalytic performance under simulated solar light.

The role of primary repair (PR) of modern day war-related colon injuries remains controversial. Retrospective review of medical records of combat-wounded soldiers with colon injuries sustained during March 2003 to August 2006 was conducted. Injuries were analyzed according to location: right (n = 30), transverse (n = 13), and left (n = 24) sided colon injuries. Two-tailed Fisher's Exact or chi tests were used for statistical analysis. Seventy-seven soldiers returned to Walter Reed Army Medical Center with colon injuries suffered during Operations Enduring Freedom and Iraqi Freedom. Twelve patients with minor colon injuries were excluded. The remaining 65 patients (mean age, 28 +/- 7 years) sustained 67 colon injuries from secondary blast (n = 38); gunshot (n = 27); motor vehicle crash (n = 1) and crush injury (n = 1). Patients arrived at Walter Reed Army Medical Center 5 days (range, 2-16 days) after injury and damage control operations (n = 27, 42%), and were hospitalized for a median of 22 days (range, 1-306 days). Follow-up averaged 311 days (median, 198 days). PR was attempted in right (n = 18, 60%), transverse (n = 11, 85%), and left (n = 9, 38%) sided colon injuries. Delayed definitive treatment of colon injuries occurred in 42% of patients. Failure of repair occurred in 16% of patients and was more likely with concomitant pancreatic, stomach, splenic, diaphragm, and renal injuries. Overall morbidity for ostomy closure after primary ostomy formation was 30%, but increased to 75% for ostomy closure after primary anastomotic or repair failure. PR of war-related colon injuries can be performed safely in selected circumstances in the absence of concomitant organ injury. Delayed anastomosis can often be performed after damage control operations once the patient stabilizes. Ostomy closure complications are more likely after anastomotic failure.

Social and traditional practices and their implications for family planning: a participatory ethnographic study in Renk, South Sudan.

Understanding what determines family size is crucial for programmes that aim to provide family planning services during and after conflicts. Recent research found that development agents in post conflict settings do not necessarily take time to understand the context adequately, translate their context understanding into programming, or adjust programming in the light of changes. South Sudan, a country that has been suffering from war for almost 50 years, has one of the highest maternal death rates and the lowest contraceptive utilization rates in the world. This research used Participatory Ethnographic Evaluation and Research (PEER) to provide a contextualised understanding of social and traditional practices and their implications for family planning. Fourteen women were recruited from 14 villages in Renk County in South Sudan in the period 2010-2012. They were trained to design research instruments, conduct interviews, collect narratives and stories and analyse data to identify, prioritize and address their maternal health concerns. As a result of wars, people are under pressure to increase their family sizes and thus increase the nation's population. This is to compensate for the men perished in war and the high child death rates. Large family size is regarded as a national obligation. Women are caught up in a vicious cycle of high fertility and a high rate of child mortality. Determinants of large family size include: 1) Social and cultural practices, 2) Clan lineage and 3) Compensation for loss of family members. Three strategies are used to increase family size: 1) Marry several women, 2) Husbands taking care of women, and 3) Financial stability. Consequences of big families include: 1) Financial burden, 2) Fear of losing children, 3) Borrowing children and 4) Husband shirking responsibility. The desire to have a big family will remain in South Sudan until families realise that their children will live longer, that their men will not be taken by the war, and that the costs of living will be met. In order to generate demand for family planning in South Sudan, priority should be given first to improve infant and child health.

To study the effect of a short period of war on the menstrual cycles of exposed women. Six months after a 16-day war, women in exposed villages aged 15-45 years were asked to complete a questionnaire relating to their menstrual history at the beginning, 3 months after, and 6 months after the war. A control group, not exposed to war, was also interviewed. The data collected were analyzed to estimate the effect of war on three groups of women: those who stayed in the war zone for 3-16 days (Group A), those who were displaced within 2 days to safer areas (Group B), and women not exposed to war or displacement (Group C-control). More than 35% of women in Group A and 10.5% in Group B had menstrual aberrations 3 months after the cessation of the war. These percentages were significantly different from each other and from that in Group C (2.6%). Six months after the war most women regained their regular menstrual cycles with the exception of 18.6% in Group A. We found a short period of war, acting like an acute stressful condition, resulted in menstrual abnormalities in 10-35% of women and is probably related to the duration of exposure to war. This might last beyond the war time and for more than one or two cycles. In most women the irregular cycles reversed without any medical intervention. II.

Gender, Attitudes Toward War, and Masculinities in Japan.

PubMed

Morinaga, Yasuko; Sakamoto, Yuiri; Nakashima, Ken'ichiro

2017-06-01

Previous studies have argued that masculinity is linked to war. We conducted a web-based survey to examine relationships between gender, attitudes toward war, and masculinities within a sample of Japanese adults of both sexes ( N = 366). Our results indicated that while men were more likely than women to accept war, the relationship between attitudes toward war and masculinities was inconclusive. Moreover, the results suggested that favorable attitudes toward war among men could be attenuated by interpersonal orientations. Based on our findings, we recommend a reexamination of attitudes toward war within the Japanese population.

Cavity Self-Stabilization and Enhancement of Laser Gyroscopes by (Coupled) Optical Resonators

NASA Technical Reports Server (NTRS)

Smith, David D.

2006-01-01

We analyze the effect of a highly dispersive element placed inside a modulated optical cavity on the frequency and amplitude of the modulation to determine the conditions for cavity self-stabilization and enhanced gyroscopic sensitivity. Hence, we model cavity rotation or instability by an arbitrary AM/FM modulation, and the dispersive element as a phase and amplitude filter. We find that anomalous dispersion may be used to self-stabilize a laser cavity, provided the magnitude of the group index of refraction is smaller than the phase index of refraction in the cavity. The optimal stabilization is found to occur when the group index is zero. Group indices with magnitudes larger than the phase index (both normal and anomalous dispersion) are found to enhance the sensitivity of a laser gyroscope to rotation. Furthermore, our results indicate that atomic media, even coherent superpositions in multilevel atoms, are not useful for these applications, because the amplitude and phase filters work against one another, i.e., decreasing the modulation frequency increases its amplitude and vice versa, with one exception: negative group indices whose magnitudes are larger than the phase index result in negative, but enhanced, beat frequencies. On the other hand, for optical resonators the dispersion reversal associated with critical coupling enables the amplitude and phase filters to work together under a greater variety of circumstances than for atomic media. We find that for single over-coupled resonators, or in the case of under-coupled coupled-resonator-induced absorption, the absorption and normal dispersion on-resonance increase the contrast and frequency of the beat-note, respectively, resulting in a substantial enhancement of the gyroscopic response. Moreover, for cavity self-stabilization, we propose the use of a variety of coupled-resonator induced transparency that is accompanied by anomalous dispersion.

UK armed forces personnel who took part in the 1991 Gulf war experienced an increase in symptomatic ill health, colloquially known as Gulf war syndrome. Speculation about an Iraq war syndrome has already started. We compared the health of male regular UK armed forces personnel deployed to Iraq during the 2003 war (n=3642) with that of their colleagues who were not deployed (n=4295), and compared these findings with those from our previous survey after the 1991 war. Data were obtained by questionnaire. Graphs comparing frequencies of 50 non-specific symptoms in the past month in deployed and non-deployed groups did not show an increase in prevalence of symptoms equivalent to that observed after the Gulf war. For the Iraq war survey, odds ratios (ORs) for self-reported symptoms ranged from 0.8 to 1.3. Five symptoms were significantly increased, and two decreased, in deployed individuals, whereas prevalence greatly increased for all symptoms in the Gulf war study (ORs 1.9-3.9). Fatigue was not increased after the 2003 Iraq war (OR 1.08; 95% CI 0.98-1.19) but was greatly increased after the 1991 Gulf war (3.39; 3.00-3.83). Personnel deployed to the Gulf war were more likely (2.00, 1.70-2.35) than those not deployed to report their health as fair or poor; no such effect was found for the Iraq war (0.94, 0.82-1.09). Increases in common symptoms in the 2003 Iraq war group were slight, and no pattern suggestive of a new syndrome was present. We consider several explanations for these differences.

Own and parental war experience as a risk factor for mental health problems among adolescents with an immigrant background: results from a cross sectional study in Oslo, Norway

PubMed Central

2006-01-01

Background An increasing proportion of immigrants to Western countries in the past decade are from war affected countries. The aim of this study was to estimate the prevalence of war experience among adolescents and their parents and to investigate possible differences in internalizing and externalizing mental health problems between adolescents exposed and unexposed to own and parental war experience. Method The study is based on a cross-sectional population-based survey of all 10th grade pupils in Oslo for two consecutive years. A total of 1,758 aadolescents were included, all with both parents born outside of Norway. Internalizing and externalizing mental health problems were measured by Hopkins Symptom Checklist-10 and subscales of the Strengths and Difficulties Questionnaire, respectively. Own and parental war experience is based on adolescent self-report. Results The proportion of adolescents with own war experience was 14% with the highest prevalence in immigrants from Eastern Europe and Sub-Saharan Africa. The proportion of parental war experience was 33% with Sub-Saharan Africa being highest. Adolescents reporting own war experience had higher scores for both internalizing and externalizing mental health problems compared to immigrants without war experience, but only externalizing problems reached statistically significant differences. For parental war experience there was a statistically significant relationship between parental war experience and internalizing mental health problems. The association remained significant after adjustment for parental educational level and adolescents' own war experience. Conclusion War exposure is highly prevalent among immigrants living in Oslo, Norway, both among adolescents themselves and their parents. Among immigrants to Norway, parental war experience appears to be stronger associated with mental health problems than adolescents own exposure to war experience. PMID:17081315

We reported natural polymer-conjugated magnetic featured urease systems for removal of urea effectively. The optimum temperature (20-60 °C), optimum pH (3.0-10.0), kinetic parameters, thermal stability (4-70 °C), pH stability (4.0-9.0), operational stability (0-250 min), reusability (18 times) and storage stability (24 weeks) were studied for characterisation of the urease-encapsulated biocompatible polymer-conjugated magnetic beads. Also, the surface groups and chemical structure of the magnetic beads were determined by using attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR). The all urease-encapsulated magnetic beads protected their stability of 30-45 % relative activity at 70 °C. A significant increase was observed at their pH stability compared with the free urease for both acidic and alkaline medium. Besides this, their repeatability activity were approximately 100 % during 4(th) run. They showed residual activity of 50 % after 16 weeks. The importance of this work is enhancement stability of immobilised urease by biocompatible polymer-conjugated magnetic beads for the industrial application based on removal of urea.

Fuels and Lubrication Researcher at the Aircraft Engine Research Laboratory

1943-08-21

A researcher at the National Advisory Committee for Aeronautics (NACA) Aircraft Engine Research Laboratory studies the fuel ignition process. Improved fuels and lubrication was an area of particular emphasis at the laboratory during World War II. The military sought to use existing types of piston engines in order to get large numbers of aircraft into the air as quickly as possible. To accomplish its goals, however, the military needed to increase the performance of these engines without having to wait for new models or extensive redesigns. The Aircraft Engine Research Laboratory was called on to lead this effort. The use of superchargers successfully enhanced engine performance, but the resulting heat increased engine knock [fuel detonation] and structural wear. These effects could be offset with improved cooling, lubrication, and fuel mixtures. The NACA researchers in the Fuels and Lubrication Division concentrated on new synthetic fuels, higher octane fuels, and fuel-injection systems. The laboratory studied 16 different types of fuel blends during the war, including extensive investigations of triptane and xylidine.

Developing information-space Confidence Building Measures (CBMs) between India and Pakistan

The Internet has changed the world in ways hitherto unknown. The international financial system, air, land and maritime transport systems are all digitally linked. Similarly most militaries are fully or partially networked. This has not only sped up the decision making processes at all levels, it has also rendered these systems vulnerable to cyber-attacks. Cyber-warfare is now recognized as the most potent form of non-kinetic war fighting. In order to prevent large scale network-attacks, cyber-powers are simultaneously spending a lot of time, money and effort to erect redundant cyber-defenses and enhancing their offensive cyber capabilities. Difficulties in creating a stablemore » environment in information-space stem from differing national perceptions regarding the freedom of the Internet, application of international law and problems associated with attribution. This paper discusses a range of Confidence Building Measures that can be created between India and Pakistan in information-space to control malicious cyber behavior and avert an inadvertent war.« less

The influence of mindfulness, self-compassion, psychological flexibility, and posttraumatic stress disorder on disability and quality of life over time in war veterans.

Posttraumatic stress disorder (PTSD) strongly predicts greater disability and lower quality of life (QOL). Mindfulness-based and other third-wave behavior therapy interventions improve well-being by enhancing mindfulness, self-compassion, and psychological flexibility. We hypothesized that these mechanisms of therapeutic change would comprise a single latent factor that would predict disability and QOL after accounting for PTSD symptom severity. Iraq and Afghanistan war veterans (N = 117) completed a study of predictors of successful reintegration. Principal axis factor analysis tested whether mindfulness, self-compassion, and psychological flexibility comprised a single latent factor. Hierarchical regression tested whether this factor predicted disability and QOL 1 year later. Mindfulness, self-compassion, and psychological flexibility comprised a single factor that predicted disability and QOL after accounting for PTSD symptom severity. PTSD symptoms remained a significant predictor of disability but not QOL. Targeting these mechanisms may help veterans achieve functional recovery, even in the presence of PTSD symptoms. © 2018 Wiley Periodicals, Inc.

Surgical and Resuscitation Capabilities for the "Next War" Based on Lessons Learned From "This War".

Freel, David; Warr, Bradley J

2016-01-01

The Army gleaned many lessons regarding the provision of medical care to casualties during the past 14 years of combat. Using these lessons learned in the Joint Capabilities and Integration Development process and through the analysis of an integrated process action team, the Army recently approved 3 changes to medical organizations that are intended to provide trauma management farther forward on the battlefield. These changes include the substitution of an emergency medicine trained physician and emergency medicine physician assistant (PA) in lieu of a general medical officer and primary care PA within the brigade combat team; reorganization of the forward surgical team into a forward surgical and resuscitative team; and the modularization of the traditional 248 bed combat support hospital. The Army anticipates that these changes related to personnel, organizations, doctrine, and materiel will enable Army medicine to provide enhanced trauma management closer to the point of a combatant's injury. These modifications are projected to begin in fiscal year 2016.

A longitudinal lifespan model of factors contributing to later-life positive adjustment was tested on 567 American repatriated prisoners from the Vietnam War. This model encompassed demographics at time of capture and attributes assessed after return to the U.S. (reports of torture and mental distress) and approximately 3 decades later (later-life stressors, perceived social support, positive appraisal of military experiences, and positive adjustment). Age and education at time of capture and physical torture were associated with repatriation mental distress, which directly predicted poorer adjustment 30 years later. Physical torture also had a salutary effect, enhancing later-life positive appraisals of military experiences. Later-life events were directly and indirectly (through concerns about retirement) associated with positive adjustment. Results suggest that the personal resources of older age and more education and early-life adverse experiences can have cascading effects over the lifespan to impact well-being in both positive and negative ways.

VMCast: A VM-Assisted Stability Enhancing Solution for Tree-Based Overlay Multicast

2015-01-01

Tree-based overlay multicast is an effective group communication method for media streaming applications. However, a group member’s departure causes all of its descendants to be disconnected from the multicast tree for some time, which results in poor performance. The above problem is difficult to be addressed because overlay multicast tree is intrinsically instable. In this paper, we proposed a novel stability enhancing solution, VMCast, for tree-based overlay multicast. This solution uses two types of on-demand cloud virtual machines (VMs), i.e., multicast VMs (MVMs) and compensation VMs (CVMs). MVMs are used to disseminate the multicast data, whereas CVMs are used to offer streaming compensation. The used VMs in the same cloud datacenter constitute a VM cluster. Each VM cluster is responsible for a service domain (VMSD), and each group member belongs to a specific VMSD. The data source delivers the multicast data to MVMs through a reliable path, and MVMs further disseminate the data to group members along domain overlay multicast trees. The above approach structurally improves the stability of the overlay multicast tree. We further utilized CVM-based streaming compensation to enhance the stability of the data distribution in the VMSDs. VMCast can be used as an extension to existing tree-based overlay multicast solutions, to provide better services for media streaming applications. We applied VMCast to two application instances (i.e., HMTP and HCcast). The results show that it can obviously enhance the stability of the data distribution. PMID:26562152

MVMs are used to disseminate the multicast data, whereas CVMs are used to offer streaming compensation. The used VMs in the same cloud datacenter constitute a VM cluster. Each VM cluster is responsible for a service domain (VMSD), and each group member belongs to a specific VMSD. The data source delivers the multicast data to MVMs through a reliable path, and MVMs further disseminate the data to group members along domain overlay multicast trees. The above approach structurally improves the stability of the overlay multicast tree. We further utilized CVM-based streaming compensation to enhance the stability of the data distribution in the VMSDs. VMCast can be used as an extension to existing tree-based overlay multicast solutions, to provide better services for media streaming applications. We applied VMCast to two application instances (i.e., HMTP and HCcast). The results show that it can obviously enhance the stability of the data distribution.

Impacts on Chinese Agriculture of Geoengineering and Smoke from Fires Ignited by Nuclear War

NASA Astrophysics Data System (ADS)

Xia, L.; Robock, A.

2013-12-01

Climate is one of the most important factors determining crop yields and world food supplies. To be well prepared for possible futures, it is necessary to study yield changes of major crops under different climate scenarios. Here we consider two situations: stratospheric sulfate geoengineering and nuclear war. Although we certainly do not advocate either scenario, we cannot exclude the possibilities: if global warming is getting worse, society might consider deliberately manipulating global temperature; if nuclear weapons still exist, we might face a nuclear war catastrophe. Since in both scenarios there would be reductions of temperature, precipitation, and insolation, which are three controlling factors on crop growth, it is important to study food supply changes under the two cases. We conducted our simulations for China, because it has the highest population and crop production in the world and it is under the strong influence of the summer monsoon, which would be altered in geoengineering and nuclear war scenarios. To examine the effects of climate changes induced by geoengineering and nuclear war on Chinese agriculture, we use the Decision Support System for Agrotechnology Transfer (DSSAT) crop model. We first evaluated the model by forcing it with daily weather data and management practices for the period 1978-2008 for 24 provinces in China, and compared the results to observations of the yields of major crops in China (middle season rice, winter wheat, and maize). Then we perturbed observed weather data using climate anomalies for geoengineering and nuclear war simulations. For geoengineering, we consider the G2 scenario of the Geoengineering Model Intercomparison Project (GeoMIP), which prescribes an insolation reduction to balance a 1% per year increase in CO2 concentration (1pctCO2). We used results from ten climate models participating in G2. For the nuclear war scenario, we consider the effects of 5 Tg of soot that could be injected into the upper troposphere by a war between India and Pakistan using only 100 Hiroshima-size atomic bombs dropped on cities. We used results from three climate models that did the same simulation. For the geoengineering scenario, without changes of agricultural technology, the combined effect of climate changes due to geoengineering and CO2 fertilization would change rice production in China by -4.6×6.0 Mt (4.5×5.9%) as compared with 1pctCO2 and would increase Chinese maize production by 20.9×6.9 Mt (14.8×4.9%) the period 46-50 years after the CO2 increase and compensating insolation reduction began. The CO2 fertilization effect compensates for the deleterious impacts of climate changes due to geoengineering on rice production, increasing rice production by 8.2 Mt and the elevated CO2 concentration enhances maize production in G2, contributing 35.5% to the total increase. While agricultural impacts may not be a serious problem for geoengineering, there are many other potential risks that need to be evaluated before geoengineering should be considered. Climate changes due to nuclear war would decrease Chinese rice production by 20×4.7%, maize production by 15×6.2% and winter wheat production by 35×19.3% for a five-year period after the soot injection, producing a major world food security crisis.

[The prevalence of war-related post-traumatic stress disorder in children from Cundinamarca, Colombia].

Pérez-Olmos, Isabel; Fernández-Piñeres, Patricia E; Rodado-Fuentes, Sonia

2005-01-01

Determining the prevalence of post-traumatic stress disorder (PTSD) related to the type of war exposure and associated factors in school-aged children from three Colombian towns. Cross-sectional epidemiological study. Representative randomised sample of 493 children aged 5-14. The children were evaluated during 2002 using semi-structured psychiatric interviews and the clinician administered PTSD scale. 167 children were evaluated in La Palma who had been chronically exposed to war, 164 in Arbeláez who had had recent war-exposure and 162 in Sopó who had not been exposed to war. War-related PTSD prevalence was calculated in each municipality. Odds ratio (OR) and chi-square were used for evaluating the association between exposure to war and PTSD and the related risk. Multivariate analysis used the logistic regression model. The affected children required specialised mental health counselling. The prevalence of PTSD resulting from war was 16,8 % in La Palma, 23,2 % in Arbeláez and 1.2% in Sopó. A 19.9 OR (CI 4.7, 119.2), 30,5 Chi-square and p = 0.000 revealed war-related PTSD association and risk for children when comparing the exposed towns to Sopó. The logistic regression showed that geographical closeness to war zone and intense emotional reaction to war increased the probability of war-related PTSD. Vulnerability factors were predominant in war-exposed towns. Poverty, parents' low educational level and child abuse predominated in La Palma. Attention-deficit and psychosomatic disorders were more prevalent in Arbeláez. War affects children's mental health; the children from the exposed towns had 19 times greater probability of war-related PTSD than those from a non-exposed town. Early therapeutic intervention is a public health priority. The results are useful for countries suffering from war, internal conflict and/or terrorism.

Effects of ionic strength and sugars on the aggregation propensity of monoclonal antibodies: influence of colloidal and conformational stabilities.

PubMed

Saito, Shuntaro; Hasegawa, Jun; Kobayashi, Naoki; Tomitsuka, Toshiaki; Uchiyama, Susumu; Fukui, Kiichi

2013-05-01

To develop a general strategy for optimizing monoclonal antibody (MAb) formulations. Colloidal stabilities of four representative MAbs solutions were assessed based on the second virial coefficient (B 2) at 20°C and 40°C, and net charges at different NaCl concentrations, and/or in the presence of sugars. Conformational stabilities were evaluated from the unfolding temperatures. The aggregation propensities were determined at 40°C and after freeze-thawing. The electrostatic potential of antibody surfaces was simulated for the development of rational formulations. Similar B 2 values were obtained at 20°C and 40°C, implying little dependence on temperature. B 2 correlated quantitatively with aggregation propensities at 40°C. The net charge partly correlated with colloidal stability. Salts stabilized or destabilized MAbs, depending on repulsive or attractive interactions. Sugars improved the aggregation propensity under freeze-thaw stress through improved conformational stability. Uneven and even distributions of potential surfaces were attributed to attractive and strong repulsive electrostatic interactions. Assessment of colloidal stability at the lowest ionic strength is particularly effective for the development of formulations. If necessary, salts are added to enhance the colloidal stability. Sugars further improved aggregation propensities by enhancing conformational stability. These behaviors are rationally predictable according to the surface potentials of MAbs.

Efficient affinity maturation of antibody variable domains requires co-selection of compensatory mutations to maintain thermodynamic stability

PubMed Central

Julian, Mark C.; Li, Lijuan; Garde, Shekhar; Wilen, Rebecca; Tessier, Peter M.

2017-01-01

The ability of antibodies to accumulate affinity-enhancing mutations in their complementarity-determining regions (CDRs) without compromising thermodynamic stability is critical to their natural function. However, it is unclear if affinity mutations in the hypervariable CDRs generally impact antibody stability and to what extent additional compensatory mutations are required to maintain stability during affinity maturation. Here we have experimentally and computationally evaluated the functional contributions of mutations acquired by a human variable (VH) domain that was evolved using strong selections for enhanced stability and affinity for the Alzheimer’s Aβ42 peptide. Interestingly, half of the key affinity mutations in the CDRs were destabilizing. Moreover, the destabilizing effects of these mutations were compensated for by a subset of the affinity mutations that were also stabilizing. Our findings demonstrate that the accumulation of both affinity and stability mutations is necessary to maintain thermodynamic stability during extensive mutagenesis and affinity maturation in vitro, which is similar to findings for natural antibodies that are subjected to somatic hypermutation in vivo. These findings for diverse antibodies and antibody fragments specific for unrelated antigens suggest that the formation of the antigen-binding site is generally a destabilizing process and that co-enrichment for compensatory mutations is critical for maintaining thermodynamic stability.

Long-term rice cultivation stabilizes soil organic carbon and promotes soil microbial activity in a salt marsh derived soil chronosequence

Soil organic carbon (SOC) sequestration with enhanced stable carbon storage has been widely accepted as a very important ecosystem property. Yet, the link between carbon stability and bio-activity for ecosystem functioning with OC accumulation in field soils has not been characterized. We assessed the changes in microbial activity versus carbon stability along a paddy soil chronosequence shifting from salt marsh in East China. We used mean weight diameter, normalized enzyme activity (NEA) and carbon gain from straw amendment for addressing soil aggregation, microbial biochemical activity and potential C sequestration, respectively. In addition, a response ratio was employed to infer the changes in all analyzed parameters with prolonged rice cultivation. While stable carbon pools varied with total SOC accumulation, soil respiration and both bacterial and fungal diversity were relatively constant in the rice soils. Bacterial abundance and NEA were positively but highly correlated to total SOC accumulation, indicating an enhanced bio-activity with carbon stabilization. This could be linked to an enhancement of particulate organic carbon pool due to physical protection with enhanced soil aggregation in the rice soils under long-term rice cultivation. However, the mechanism underpinning these changes should be explored in future studies in rice soils where dynamic redox conditions exist. PMID:26503629

The stability of portfolio investment in stock market crashes with Markowitz portfolio is investigated by the method of theoretical and empirical simulation. From numerical simulation of the mean escape time (MET), we conclude that: (i) The increasing number (Np) of stocks in Markowitz portfolio induces a maximum in the curve of MET versus the initial position; (ii) A critical value of Np in the behavior of MET versus the long-run variance or amplitude of volatility fluctuations maximumlly enhances the stability of portfolio investment. When Np takes value below the critical value, the increasing Np enhances the stability of portfolio investment, but restrains it when Np takes value above the critical value. In addition, a good agreement of both the MET and probability density functions of returns is found between real data and theoretical results.
