The question of the impact of war on ecosystems still remains secondary in the internal and external policy of states, society and the agenda of international organizations. From the point of view of losses in monetary terms, the values of ecosystem damages obtained in the work, which are a consequence of the impact of hostilities on the environment, correspond to the annual budgets of the largest countries in the world or exceed them. The presented calculations significantly exceed the known normative methods, the use of which in the conditions of war is limited in space and time. Objective difficulties associated with the uncertainty of many processes of the development of ecological systems and their reaction to the multifactorial impact of war are also significant limitations. Therefore, as part of the study, a method of assessing the impact of war on the environment is proposed, which is based on the patterns of energy flows in ecosystems from the moment it is binding by producers. This made it possible to take into account in the calculations the principle of functional integrity of the ecological system, according to which the destruction or damage of the components of a functionally whole environment will necessarily cause negative phenomena in the development of ecological systems. The results are presented in the form of real values of ecological losses in energy and monetary equivalents, as consequences of the loss of ecosystem services. As the results of the research show, the minimum amount of damage to ecosystems from Russian tanks is 43,500 USD per day. Environmental damage from Russian fighter jets has been estimated at $1.5 billion per week since the start of the war. Noise from military operations causes losses of at least 2.3 billion US dollars per year. The obtained results create prerequisites for improving the system of ensuring environmental safety at the local, state, and international levels and transferring the obtained solutions into safety-shaping practice. 展开更多

The legacy of the human misery caused by the application of the herbicides including Agent Purple and Agent Orange contaminated with unknown amounts of dioxin TCDD and Agent Blue, the arsenic-based herbicide, sprayed over the jungles, rice fields, and hamlets of Vietnam is still haunting us today. Why did this happen? Could it have been prevented? Was it necessary United States military strategy? Was it an intentional decision to inflict this blight on the enemy soldiers and the Vietnamese, Cambodian, and Laotian civilians, to poison their land and cause generations of harm? Alternatively, was it an unpreventable accident in the march of military history? What patterns in the U.S. government’s thought process could be identified as the cause, which led to the decision to use these herbicides as tactical chemical weapons? If the introduction of herbicide (chemical) weapons had not been made, would the outcome of the Vietnam War and the Secret Wars in Laos and Cambodia have been any different? The objective of this treatise is to outline the role of world events and backgrounds and the role of the leaders, U.S. military, CIA, USDA, U.S. State Department, the U.S. President appointed Ambassadors to Vietnam and Laos, chemical companies, and President Diệm’s Republic of Vietnam (RVN) government and military. Their collective advice led to the decision to use herbicides as military and environmental chemical weapons in the Second Indochina War. Were the National interests achieved by U.S. military strategy in the RVN using herbicide weapons worth the long-term environmental and human health consequences in Vietnam, Cambodia, and Laos? Did it impact the outcome of the Second Indochina War? 展开更多

The frequent rebellions in Northern Manchuria during the Third Revolutionary War occurred in the special context of the struggle between the Kuomintang(KMT)and the Communist Party of China(CPC)for Northeast China after the victory of the Anti-Japanese War.The rebellion reached its peak during the KMTs attack on Northeast China,followed by a second wave of rebellion after the defeat in the Defensive Battle of Siping.It tended to disappear after the downfall of the Jiang Pengfei Group.In addition to the blind recruitment of the CPC in traditional narratives,the instigation of the KMT,the traditional mutiny of the old army,the limitations of the early work of the Northeast Anti-Japanese United Army,the early activities of the KMT,and the regional conflicts between the local and foreign forces are also important reasons for the concentration of rebellions. 展开更多

BACKGROUND Psychosocial and physical trauma are known risk factors for irritable bowel syndrome(IBS),including in war veterans,whereas war exposure in civilians is unclear.Nicaragua experienced two wars,1970-1990:The Sandinistas Revolution(1970s)and The Contra War(1980s).Our aim was to investigate the role of exposure to war trauma in the subsequent development of IBS in the context of an established health surveillance system(11000 households).AIM To investigate in a civilian population the relationship between exposure to war trauma and events and the subsequent development of IBS in the context of an established public health and demographic surveillance system in western Nicaragua.METHODS We conducted a nested population-based,cross-sectional study focused on functional gastrointestinal disorders based on Rome II criteria.1617 adults were randomly selected.The Spanish Rome II Modular Questionnaire and Harvard Trauma Questionnaire were validated in Nicaragua.War exposure was assessed with 10 measures of direct and indirect war trauma and post-war effects.Multiple exposures were defined by≥3 measures.RESULTS The prevalence of IBS was 15.2%[Female(F)17.1%,Male(M)12.0%],war exposure 19.3%(F 9.3%,M 36.7%),and post-traumatic stress disorder(PTSD)5.6%(F 6.4%,M 4.3%).Significant associations with IBS in the civilian population were observed(adjusted by gender,age,socioeconomic status,education):physical and psychological abuse[adjusted odds ratio(aOR):2.25;95%confidence interval:1.1-4.5],witnessed execution(aOR:2.4;1.1-5.2),family member death(aOR:2.2;1.2-4.2),and multiple exposures(aOR:2.7;1.4-5.1).PTSD was independently associated with IBS(aOR:2.6;1.2-5.7).CONCLUSION An enduring association was observed in the Nicaragua civilian population between specific civil war-related events and subsequent IBS.Civilian populations in regions with extended armed conflict may warrant provider education and targeted interventions for patients. 展开更多

Gulf War Illness(GWI) encompass a spectrum of maladies specific to troops deployed during the Persian Gulf War(1990–1991). There are several hypothesized factors believed to contribute to GWI, including(but not limited to)exposures to chemical agents and a foreign environment(e.g., dust, pollens, insects, and microbes). Moreover, the inherent stress associated with deployment and combat has been associated with GWI. While the etiology of GWI remains uncertain, several studies have provided strong evidence that chemical exposures, especially neurotoxicants,may be underlying factors for the development of GWI. This mini style perspective article will focus on some of the major evidence linking chemical exposures to GWI development and persistence decades after exposure. 展开更多

Marxist political economy provides a perspective for grasping the root cause of the China-US trade war.The international relations of production,which stem from the international division of labor,shape the distribution of international economic interests and the political status of countries.Traditionally,developing countries have been subjected to the“periphery”in the international division of labor.In the new global value chain,developing countries have remained in a subordinate position characterized by“technological-market”dependence.To achieve the goal of building a strong modern nation,China must escape the“technological-market”dependence.Yet China’s efforts and achievements in escaping dependent development are deemed as a threat to US vested interests in the international markets.To preserve the economic foundation of its hegemony,the US has resorted to a trade war to contain China’s development. 展开更多

Microbial pathogens include bacteria, viruses, fungi, and parasites and together account for a significant percentage of acute and chronic human diseases. In addition to understanding the mechanisms by which various pathogens cause human disease, research in microbial pathogenesis also addresses mechanisms of antimicrobial resistance and the development of new antimicrobial agents and vaccines. Answering fundamental questions regarding host-microbe interactions requires an interdisciplinary approach, including microbiology, genomics, informatics, molecular and cellular biology, biochemistry, immunology, epidemiology, environment and interaction between host and microbe. Studies investigating the direct effects of pollutants on respiratory tract infections are very vast, but those interested in the role of a pre-existing disease and effects of the exposure on the response to secondary stresses are few. In an experimental study at concentrations of air pollutants found in urban environments, frank toxicological responses are rarely observed, however, exposure to secondary stress like the respiratory challenge with infectious bacteria can exacerbate the response of the experimental host. The models like experimental, mechanical, and mathematical are the most abstract, but they allow analysis and logical proofs in a way that other approaches do not permit. The present review is mostly concerned with these model representations particularly with a novel mathematical model explaining the interaction between pathogen and immunity including the equivalence point. 展开更多

The United States military operation against the Ho Chi Minh Trail traffic began in 1959. The (PAVN) connected a series of old trails leading from North Vietnam to South Vietnam via Laos and Cambodia. In the 1960s the network of trails was expanded. Trail traffic was interdicted by repeated CIA (Air America) and US Air Force (Operation Ranch Hand) tactical herbicide spraying and bombing missions. During the late 1960s, the Khmer Rouge Army slowly grew in eastern Cambodia during a time when America was spraying and bombing the Ho Chi Minh Trail. On February 22, 1969, the PAVN launched a new offensive against American forces in South Vietnam from their sanctuaries in Cambodia. President Richard Nixon and Dr. Henry Kissinger, decided to spray and bomb Cambodia, a neutral country, to eliminate the PAVN sanctuary base camps. The damage and loss of life as a result of U.S. air campaign resulted in the insurgency (Khmer Rouge) being able to recruit civilian members. This created a dual effect of strengthening the popularity of the Khmer Rouge, led by Pol Pot, enabling him to overthrow the Khmer Republic in 1975. The primary objectives of this study are to determine the political impacts and consequences of: 1) the 1959 United States secret war on the Ho Chi Minh Trail in Cambodia and 2) the 1969 President Nixon’s decision to destroy the PAVN bases hidden in the Cambodian jungles. These United States secret wars in Cambodia had long-lasting effects on Cambodian political, social, and economic stability. 展开更多

The current research overlaps a linguistic and a legal analysis of public international law in the Ukrainian case.Based on both official documents and public declarations,it explains the grounds for the wide range of understandings that the two common concepts-peace and war-may be bearing depending of the angle of looking at the matter and depending on the actor invoking them.The study develops the reasons likely to have been considered by President Putin when insisting to refer to the Russian military action started in Ukraine in February 2022 as“special military operation”instead of“war”and the cardinal difference in terms of legal impact for such a linguistic choice.It also builds on the elements which could serve as a basis for achieving a deal in obtaining peace in Ukraine,while tackling on the possible geopolitical,public communication and diplomatic hurdles,and offering clues for strategic analysis of the matter. 展开更多
