在现代的劳动关系中劳资关系是《劳动合同法》的一个核心的内容。而《劳动合同法》能否正确按照法律程序解除,并且保证劳资双方的共同利益。是每个国家劳动法所制定的一个标准。本文笔者将研究中国和哈萨克斯坦关于《劳动合同法》劳动合同解除的一系列问题。将会主要讨论中国和哈萨克斯坦两国对于劳动合同解释权的含义及《劳动合同法》对劳动合同解除与救济的一系列的规定。并且希望能够找到中哈劳动合同解除制度的异同点。并且能够通过中哈劳动合同解除制度比较研究,得出一定的立法反思。本文将主要通过文献法以及相应的一些法学理论对中哈劳动合同解除进行研究。得出了中哈两国劳动合同解除制度的相同点,都有预期协商解除劳动合同,还有就是在解除劳动合同方式以及赔偿费用。而中哈劳动合同解除制度的不同点可以总结为哈萨克斯坦共和国劳动法更具有公平性而中国劳动法更具有人情性。哈萨克斯坦劳动合同解除制度对中国的借鉴有第一点,让用人单位和劳动者处于平等地位。第二点在经济性裁员中,用人单位应该尽自己最大的力量为失去工作的人员寻找其他的岗位。中国劳动合同解除制度对哈萨克斯坦的借鉴有哈萨克斯坦的劳动法应该像中国一样对有多年岗位或只有特殊技术的人进行保护。第二点应该向中国《劳动合同法》对于雇主进行解雇应该有一个具体的评判标准。就业是每个现代人来获得自我价值以及生活的手段和途径。国家的劳动法的完善将会给国家的人民带来巨大的福祉,也让这个社会更加的公平。法律让用人单位以及劳动者都有其权利和义务。相信中国和哈萨克斯坦两国,通过借鉴对方的优点未来两国的法律会更加的完善与公平。

Introduction: Plasma cell neoplasms are monoclonal proliferations characterized by the secretion of an immunoglobulin product known as component "M" or monoclonal. The World Health Organization (WHO 2008) defines as plasma cell neoplasms the following: plasma cell myeloma, plasmacytoma and those syndromes defined by immunoglobulin deposits and primary amyloidosis, The objective of the present work was to correlate their clinical, morphological and phenotype characteristics in 21 patients. Material and Methods: A 2-year retrospective review was performed of the files of the surgical pathology laboratory and of the hematology service of the General Hospital of Mexico, searching for patients with a diagnosis of plasma cell neoplasm. We analyzed the following variables: age, gender, clinical symptoms, evolution, localization, laboratory tests, morphology, and expression of immunohistochemical markers. Of the 21 patients, 12 (57.1%) corresponded to plasma cell myelomas and 9 (42.8%) were plasmacytomas (seven extraosseous and two solitary bone plasmacytoma);women predominated with 61.4% and age ranged between 22 and 84 years. Mass and epistaxis were observed in the patients with plasmacytomas, and symptoms of medullary compression and anemia were observed in those patients with plasma cell myeloma. The time of symptomatology varied from 3 to 12 months. Laboratory tests revealed that lactate dehydrogenase (LDH), beta 2 microglobulin, C-reactive protein were altered and that hypercalcemia and anemia were present more in the systemic form of the disease. Treatment depended on the clinical staging and laboratory data. Mature forms predominated morphologically. Immunohistochemical stain revealed a constant expression for CD 138, six patients expressed CD 56, and expression of the Kappa and Lambda light chains was while.

The expansion of hydroponics in many countries of the world in the last few decades may be ascribed to the ability of soilless growing systems to avoid various problems arising from the use of the soil. Cucumber （Cucurnis sativus L.） and zucchini （Cucurbita pepo L.） plants were grown in closed-soilless culture under unheated-greenhouse conditions at the experimental farm of University of Tuscia, Central Italy to evaluate the effects of four substrates （rockwool, pumice, perlite, and cocofiber） on growth, yield and plant mineral composition. For both cultures, plants grown in cocofiber, perlite and pumice yielded more than those grown in rockwool. The better temperature regime in cocofiber, perlite and pumice was due to the greater thermal inertia compared to rockwool slabs. Thc concentration of N in zucchini and cucumber leaves was significantly higher in cocofiber, perlite and pumice in comparison to the rockwool treatment. The concentration of K was significantly affected by the substrate only for the zucchini squash with the highest value recorded on the organic substrate （cocofiber）, whereas the Ca concentration was significantly influenced by the growing media only for cucumber with the highest value observed on pumice. Finally, the lowest Mg concentration in leaf tissue was observed on plants grown with the rockwool substrate for both zucchini squash and cucumber. We can conclude that cocofiber, perlite and pumice are suitable for zucchini and cucumber production in closed soilless system, whereas the use of rockwool is more suitable for crops grown under heated greenhouse conditions.

《国家地理》杂志有自己独特的摄影风格,而这一独特的摄影风格的形成与一个特殊群体有着直接的关系,这个特殊群体的共同特征就是他们都是布里亚特人。他们对大自然的热爱、坚韧不拔的探索精神以及严谨踏实的职业精神,为《国家地理》风格形成奠定了基础,不仅如此,其中的崔比科夫还历史性地挽救了当年处于危难境地的《国家地理》,从这个意义上说,没有这些布里亚特人,今天的《国家地理》也许完全是另外一个样子,也许,《国家地理》在文化传播方面的走向与价值也会因此而不同。这一切始于一个俄国布里亚特族人贡博扎布·崔比科夫拍摄的关于西藏的图片,而且这些当时世界上最早的还无人知道神秘西藏的图片首发于《国家地理》杂志。这些图片对杂志的独特摄影风格有很大的影响。《国家地理》杂志全世界闻名的起点是从这一刻开始的。到今天为止,很多俄国布里亚特摄影师和记者在《国家地理》杂志工作,他们也对杂志的发展作出了很大的贡献。更重要的是这些俄国布里亚特摄影师和记者以《国家地理》杂志为媒介,在世界文化交流中,在某种意义上成为文化传播的使者,而且,在《国家地理》杂志工作的众多摄影师和记者当中,不论是历史的偶然,还其他什么缘故,在《国家地理》杂志发展历程中,前前后后如此巧合地有这样一批俄国布里亚特摄影师和记者承担着文化传播的光荣使命。
