The rapid expansion of the field of optical communications,in both its classical and quantum variants,has led to a desire to increase the bandwidth available for encoding information[1,2].Effects such as crosstalk[3]due to polarization rotation,linearly polarized(LP)mode interactions,four-wave mixing,and linear dispersion often reduce the maximum achievable bandwidth in classical communication systems,while degrading the fidelity and security of their quantum *** angular momentum(OAM)modes are independent eigenstates suitable for spatial division multiplexing in fiber and free-space transmission.

A cross-sectional study was conducted to determine the Seropositivity of Toxoplasma gondii in water buffalo in three Iraqi governorates (Baghdad, Dhi Qar, and Maysan) and to estimate the risk aspects related to infestation throughout the period from January to December 2019. A total of 430 serum samples were inspected with a commercial ELISA (Enzyme linked immunosorbent assay) kit. Indirect multi-species kit. The overall Seropositivity of T. gondii in the examined local buffalo was 7.4%, and the highest rate (9.3%) was in Baghdad Governorate. A multivariate regression analysis revealed that adult buffalo (OR = 7.10;95% CI: 0.87-57.68;P = 0.067) and young herds (OR = 8.42;95% CI: 1.07-66.02;P = 0.043) were more subject to infestation from young buffalo and large herds. Furthermore, the hazard of toxoplasmosis was increased in winter especially among animals in contact with cats. It is therefore requisite to determine risk aspects to evaluate which mitigation, control, prevention and procedures should be carried out to diminish, control and prevent infestation with T. gondii and its propagation.

Some of the chemical and physical water qualities of the Graff River in the city of Kut were studied, and for two sites of the river, One was at the Crimea site, the other in the Jihad district, and for the period from October/2018 to March/2019, Seven variables of river water have been analyzed: temperature PH, electrical conductivity, TDS, turbidity, alkaline, and chloride. The results showed that most of the chemical and physical water properties of the river were in normal proportions and did not rise, except for the turbidity, which was at a very high level, and that the pH values were close to the basal side. The results of the statistical analysis revealed positive significant relationships between the pH and (chloride and TDS). On the other hand, between electrical conductivity and both previous variables as well. And a negative significant connection between temperature and alkaline.

2010年后巴基斯坦和俄罗斯关系变化的动因分析

作者： Imran imad 吉林大学

学位级别：硕士

1947年8月14日,巴基斯坦宣布独立,并于1948年5月1日与苏联建立外交关系。当时的总理利亚卡特·阿里·汗(Liaquat Ali Khan)受到了苏联和美国的访问邀请,然而,他却选择前往美国,因为他认为美国在对巴基斯坦的援助方面具有更大的潜力。由... 详细信息

1947年8月14日,巴基斯坦宣布独立,并于1948年5月1日与苏联建立外交关系。当时的总理利亚卡特·阿里·汗(Liaquat Ali Khan)受到了苏联和美国的访问邀请,然而,他却选择前往美国,因为他认为美国在对巴基斯坦的援助方面具有更大的潜力。由于冷战的原因,巴基斯坦与苏联的关系经历了多次波动。苏联解体后,俄罗斯试图改善与巴基斯坦的关系,但两国之间仍然存在信任赤字。但在2010年之后,巴基斯坦和俄罗斯之间的关系得到改善,变得更加密切,双方之间的高层外交互访增多,武器贸易与合作增加。基于此,本文分析了2010年至今巴基斯坦与俄罗斯之间的关系演变动态。与此同时,美国和巴基斯坦之间的关系趋于紧张。2010年初,俄罗斯与阿富汗、巴基斯坦、塔吉克斯坦在莫斯科召开了会议,阿富汗是此次会议的焦点。这次会议标志着莫斯科重新参与阿富汗事务,对巴基斯坦来说意义重大,尤其是在印度缺席的情况下。此外,这一事件发生在美国和巴基斯坦在阿富汗问题上的关系日益紧张的特定时期。此后,第二年发生的一系列事件导致伊斯兰堡和华盛顿的关系突然恶化,其中包括美国在巴基斯坦的军事行动导致本·拉登(Osama bin Laden)的死亡,以及2011年11月美国和巴基斯坦军队无意发生的一场跨国枪战,导致多名巴基斯坦军官和军事人员在靠近阿富汗的一个边界点死亡。巴基斯坦陆军参谋长卡亚尼(Ashfaq Kayani)曾于2011年访问莫斯科,并向俄罗斯有效承诺改变了的政策和军事需求。卡亚尼要求莫斯科重新评估其对禁止向巴基斯坦提供武器供应的立场。2012年8月,巴基斯坦空军上将塔希尔·拉菲克·巴特(Tahir Rafiq Butt)对巴基斯坦进行了访问,作为回应,俄罗斯空军上将维克托·邦达列夫(Viktor Bondarev)于2013年4月访问了巴基斯坦。莫斯科花了两年时间解除对巴基斯坦的武器禁运,此举激怒了印度。因为在过去,俄罗斯在武器售卖决策中优先考虑的是印度而非巴基斯坦。武器禁运的解除向巴基斯坦和印度传达了一个明确的信号,即一个改变了的俄罗斯已经出现,它在不断变化的南亚地缘政治中重塑了其战略重点。我的研究问题是,“此前巴基斯坦和俄罗斯的双边关系一直相对薄弱,但为什么自2010年左右以来,它们之间的关系却在稳步提升?”大约自2010年以来,俄罗斯和巴基斯坦之间的关系持续改善,主要是由于与全球权力平衡有关的安全和地缘政治因素。一方面,由于与美国及其盟友的关系不断恶化,俄罗斯不得不越来越多地与新的盟友建立联系。同时,印度与美国之间关系的加强以及印度与巴基斯坦之间日益增长的不信任导致巴基斯坦与美国之前相对稳固的关系逐渐恶化。此外,阿富汗事件为巴基斯坦和俄罗斯之间加强合作增添了更多动力。俄罗斯的外交政策经历了一次调整,其特点是转向亚洲,寻求新的伙伴关系,这表明俄罗斯希望其在全球范围内的参与更加多样化。同时,联合国和上海合作组织等国际组织在塑造巴基斯坦和俄罗斯之间的全球外交与合作方面发挥了重要作用。本文分析的重点是引起这一战略转向的驱动因素,以及战略转向对于地区和全球权力动态的广泛影响,它旨在了解这些有着独特历史轨迹和地缘政治需求的国家是如何找到合作的共同点的。此外,俄罗斯与中国日益加强的战略联系以及与西方国家关系的弱化,影响了其在巴基斯坦的利益,即巴基斯坦为俄罗斯提供了经济机会和战略区域。俄罗斯和巴基斯坦都支持阿富汗问题的包容性政治解决方案,并认识到通过谈判解决问题以实现持久和平的必要性。本文研究的意义在于,俄罗斯在南亚具有的战略和经济利益需要我们对其与南亚的关系进行科学分析。冷战的政治背景、中国不断扩大的作用,以及美国从阿富汗撤军这一系列的事件都凸显了了解巴基斯坦和俄罗斯等国家的利益和双边关系的重要性。分析这些国家如何塑造它们之间的关系,有助于我们更好地理解外交政策,并将其与国际关系之辩联系起来。本研究采用现实主义理论框架来分析巴俄关系。现实主义理论认为,国家是参与国际关系的主要行为体,国家为其在国际上的主导地位和自身安全而竞争,国家的最终目标是实现权力的最大化,而维持权力的平衡就会带来和平。正如斯科特·伯奇尔(Scott Burchill)描述的那样,古典现实主义将国家视为具有独特利益的独立实体,国家受到巩固权力、安全和生存等因素的影响。该理论承认国际体系的无政府性质,即各国依靠自身资源而生存。同时,该理论认为人性和共同的文化价值观等历史因素也在影响国家行为方面发挥着重要作用。对于巴基斯坦和俄罗斯的关系,古典现实主义者认为,两国优先考虑自身的生存和国家利益,从而导致他们之间的政治、军事和经济联系的增长。此外,由于地区动态的变化和美国对印度支持程度的改变,巴基斯坦寻求与俄罗斯建立战略联盟。权力平衡的概念对于理解两国之间的关系至关重要,因为在冷战期间,尽管两国存在着
