This work presents a systematic study of the geometric, electronic and magnetic properties of Pd clusters pristine and mono- and bi[1]doped with Mn: Pdn, Pdn−1Mn, Pdn−2Mn2 where n ≤13. We have used the density functional formalism with the spin polarized generalized gradient approximation. From the variety of possible structures with thirteen atoms, we found the icosahedral configuration to be the most stable as compared to the hexagonal, cub-octahedral and buckled bi-planar. The change in magnetic behavior of Pd clusters after doping with Mn has been observed. This communication is an attempt to understand that behaviour.
本文系统地研究了Mn: Pdn, Pdn - 1Mn, Pdn - 2Mn2掺杂的原始Pd团簇和单、双[1]的几何、电子和磁性能。我们使用了密度泛函形式和自旋极化广义梯度近似。从13个原子的各种可能结构中,我们发现二十面体的结构与六边形、立方八面体和双平面弯曲结构相比是最稳定的。研究了掺杂锰后钯团簇磁性行为的变化。这次交流是为了理解这种行为。

This paper presents gurukul system of education as the main concern in the quality of human beings. Education is the only means of civilizing ourselves to maintain high qualities of integrity, devotion, sincerity and an ethical and moral purpose in our national life. The goal of our national education should be to supply a constant stream of knowledge, character, fearless open minded, truthful, and patriotic people, who will become the basic material, for building up the nation. Gurukul Style of Education system is a 5000-year old Hindu tradition of transmitting higher knowledge and enlightenment to the students by yogic powers by the guru with an aim to develop the latent yogic powers of the child and build him up into a moral and spiritual power.

Natural Hydroxyapatite (HA) with chemical formula Ca10(PO4)6(OH)2 is a major mineral storage form of calcium and phosphorous in bone and it has been applied in many fields. In the present study, HA was extracted from biowaste; namely the buffalo bone by alkaline hydrolysis process followed by calcination at 900°C with holding time 6 hrs. in muffle furnace. The isolated material was analyzed by X-ray Diffraction (XRD), Fourier Transform Infra-Red Spectroscopy (FTIR) and Field Emission Scanning Electron Microscopy (FESEM) etc. The SEM image suggested the isolated material had rod shaped and agglomerated. FTIR study indicated the phosphate and hydroxide were the major functional groups along with carbonate present in it. Further, XRD analysis inferred that the isolated material was only HA phased. The specific surface area of the isolated HA was determined by methylene blue adsorption method and it was found to be 141.12 m2 /g and pH point of zero charge (pHPZC) of the extracted biomaterial was determined to be 6.8 by pH the drift method. Thus the pure HA powder was synthesized by an environmentally friendly, cost effective method and may be applicable in many fields including waste water treatment and biomedicine etc.
化学式为Ca10(PO4)6(OH)2的天然羟基磷灰石(HA)是骨中钙、磷的主要矿物质储存形式,在许多领域得到了应用。本研究从生物废弃物中提取透明质酸;即水牛骨经碱性水解,900℃煅烧,保温6小时。在马弗炉。采用x射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、场发射扫描电镜(FESEM)等对分离材料进行了分析。扫描电镜图像显示,分离的材料呈棒状、团块状。红外光谱(FTIR)研究表明,其主要官能团为磷酸盐和氢氧化物,并伴有碳酸盐的存在。进一步通过XRD分析可知,分离得到的材料仅为HA相。亚甲基蓝吸附法测定分离得到的透明质酸的比表面积为141.12 m2 /g, pH漂移法测定提取的生物材料的零电荷点pH值为6.8。因此,纯透明质酸粉末的合成是一种环保、经济的方法,可用于废水处理和生物医学等领域。

Role of Civil Society in Community Development of Nepal 民间社会在尼泊尔社区发展中的作用
Pub Date : 2023-11-02 DOI: 10.3126/pdmdj.v5i2.59606

This study is based on the role of civil society in community development in Nepal. It is mainly prepared by using secondary sources. Data is obtained through articles/newspapers/clubs of the organization. The role of civil society in training and skill development, group formation and mobilization is assessed to be satisfactory. In the areas of health and hygiene, education, drinking water, transport and communication too, the role is likely to improve in the coming days. The relationship between groups and individuals in the community has appeared to be good. Most civil societies agree on good relationships between groups and individuals. The main problems of civil society are issues of the sustainability of their activities and political bias. Organizations depend on donor funds and activities as they propose; so there is duplication of programs and activities in the community. The activities are very short and do not have a fixed duration required by the community; it is due to the dependence of the donor for the fund. Civil society is the main subject and agent of community development. It knows the cultural, social, political and geographical situation. The process of social mobilization and mobilization of resources is the pioneering path of civil development. Group training and mobilization are found to be very good in the community. Therefore, this study shows a great need for civil society in community development. The function of civil society is very respectable. People want to expand their activities but the civil society cannot expand because of lack of funds. The ground of honor developed by civil societies in terms group formation, social mobilization, resource mobilization, and saving habits in groups is remarkable. Civil society (CS) in Nepal has played an important role in the economic and political transformation of the country over the past three decades. As Nepal changes into a three-tier federal government system, the environment in which civil society organizations (CSOs) operate is also changing.
本研究基于尼泊尔社区发展中公民社会的作用。它主要是利用二手资料制备的。数据通过该组织的文章/报纸/俱乐部获得。民间社会在培训和技能发展、团体组建和动员方面的作用经评估是令人满意的。在保健和卫生、教育、饮用水、运输和通讯领域,这种作用可能在今后几天得到加强。社区中群体和个人之间的关系似乎很好。大多数公民社会都认同群体和个人之间的良好关系。民间社会的主要问题是其活动的可持续性和政治偏见问题。各组织依赖捐助者的资金和活动;所以社区里有重复的项目和活动。活动时间很短,没有社区要求的固定时间;这是由于捐助者对基金的依赖。市民社会是社区发展的主体和推动者。它了解文化、社会、政治和地理情况。社会动员和资源动员的过程是公民发展的先锋路径。团体训练和动员在社区中被发现是非常好的。因此,本研究显示了社区发展对公民社会的巨大需求。公民社会的功能是非常值得尊敬的。人们想要扩大活动范围,但由于缺乏资金,公民社会无法扩大。民间社会在群体形成、社会动员、资源动员、群体储蓄习惯等方面形成的荣誉基础是显著的。过去三十年来,尼泊尔的公民社会(CS)在该国的经济和政治转型中发挥了重要作用。随着尼泊尔转变为三级联邦政府体制,民间社会组织的运作环境也在发生变化。

We have developed a straightforward and uncomplicated technique for creating alkaline exchange membranes (AEMs) that possess both high alkaline durability and improved ionic conductivity. This method provides an appealing alternative to conventional approaches, notably by eliminating the need for the use of the carcinogenic reagent chloromethyl methyl ether, typically employed in AEM preparation. Examination of the membranes via scanning electron microscopy (SEM) reveals a consistently smooth surface. Augmenting the ion-exchange material's weight percentage in the casting solution results in enhanced water content, ion exchange capacity, and electrical conductivity. Importantly, our approach entirely circumvents the use of the hazardous chloromethy l methyl ether reagent, commonly associated with AEM preparation. TGA for thermal stability and chemical stability, conductivity with impedance data, and electrochemical tests are going on. The outcomes of this study present an appealing alternative to traditional methods for AEM synthesis.
我们已经开发了一种简单而简单的技术来制造碱性交换膜(AEMs),它具有高碱性耐久性和改善的离子电导率。该方法为传统方法提供了一种有吸引力的替代方法,特别是通过消除使用致癌试剂氯甲基甲醚的需要,这种试剂通常用于AEM制备。通过扫描电子显微镜(SEM)检查膜显示一致光滑的表面。增加离子交换材料在铸造溶液中的重量百分比,可以提高水含量、离子交换能力和导电性。重要的是,我们的方法完全避免了使用有害的氯甲基醚试剂,通常与AEM制备相关。热稳定性和化学稳定性的热重分析仪,电导率与阻抗的数据,以及电化学测试正在进行中。本研究的结果为AEM合成的传统方法提供了一个有吸引力的替代方案。

Mythic realities in Newar arts and cultural representations of the socio-cultural activities noted in the folklores, tales, practices and performances in Patan and Kirtipur are mysteries. Ritual activities like Lakhe Dances, Jatras and other rituals are related with the historical events, facts and imaginary-mysterious beliefs. Myth is an excavating tool for meaning making of the artistic, cultural and historical sayings noted in the tales that can catch out the themes observing the coverage of crafts in applying the artistic and literary techniques. Newar Arts, Newa Dance, Dhime Dance, Lakhe Dance and other magical activities and rituals of Patan and Kirtipur are culturally connected with mythic realities of folklores. The cultural study helps to study the arts, culture and literature and myth making in creating the meanings through library and internet-based resources and it is also prepared on the basis of field visit reports and therefore this study applies both the qualitative and quantitative approaches. Objective of this article is to expose the mythical images and it analyzes present events in field-based method studying the human emotions, feelings and their cultural practices. It also investigates on the subjects of religious activities, socio-cultural practices and cultural representations of the past reality and present changes in a different way. This article presents a brief sketch of a new perspective on cultural orientation to mythical world as myth and mystery reflecting on the past activities and creating the meanings in the present. Cultural study is one of the tools to excavate Patan and Kirtipur’s history and so in this article Stuart Hall’s ideas are applicable.
尼瓦尔艺术中的神话现实,以及帕坦和基尔蒂普尔的民间传说、故事、习俗和表演中社会文化活动的文化表现,都是神秘的。Lakhe舞蹈、Jatras和其他仪式等仪式活动与历史事件、事实和虚构的神秘信仰有关。神话是对故事中所记载的艺术、文化和历史谚语进行意义挖掘的工具,它可以在运用艺术和文学技巧的过程中观察工艺的覆盖范围,从而抓住主题。Newar艺术、Newa舞蹈、Dhime舞蹈、Lakhe舞蹈和其他帕坦和Kirtipur的魔法活动和仪式在文化上与民间传说的神话现实有关。文化研究有助于通过图书馆和网络资源来研究艺术、文化、文学和神话制作在创造意义方面的作用,它也是在实地访问报告的基础上准备的,因此本研究采用定性和定量方法。本文的目的是揭示神话中的形象,并以现场为基础的方法分析现实事件,研究人类的情感、感受及其文化习俗。它还以不同的方式调查宗教活动、社会文化习俗和过去现实的文化表现以及目前的变化。本文简要介绍了一种以神话和神秘为神话世界的文化取向的新视角,它反映了过去的活动并创造了现在的意义。文化研究是挖掘帕坦和基尔蒂普尔历史的工具之一,因此在本文中可以应用斯图尔特霍尔的观点。

Generalized Anxiety Disorder Among University Students Due To COVID-19 新冠肺炎导致的大学生广泛性焦虑障碍
Pub Date : 2023-11-02 DOI: 10.3126/pdmdj.v5i2.59600
Pitambar Acharya, Sudip Pokhrel
Generalized Anxiety Disorder (GAD) is a common but urgent mental health problem during disease outbreaks. With the outbreak of COVID-19’s second wave, educational institutions were closed, and the students had to remain confined to online teaching[1]learning, which might create many psychological problems. This study assesses the prevalence of generalized anxiety disorder among university youth students due to COVID-19. A cross-sectional online survey was conducted among 176 (response rate: 76.5%) university students studying at the Central Department of Education. The Generalized Anxiety Disorder scale (GAD-7) questionnaire was used to assess anxiety disorder. Students were selected using a simple random sampling technique and sent the questionnaire link created in the Kobo toolbox to them requesting voluntary participation. The collected responses were analyzed using descriptive statistics and multivariate logistic regression to find the GAD prevalence and associated factors. A study found that 47.7% of university students had generalized anxiety disorder due to COVID-19. Older participants had a lower likelihood of anxiety disorder compared to those under 30 (OR 0.267). Buddhists had higher odds than Hindus (OR 5.237), and students in Bagmati and Lumbini Provinces had higher odds than those in Koshi Province (OR 8.116 and OR 6.086, respectively). Students not infected with COVID-19 had higher odds of anxiety disorder than infected students (OR 7.564), and those not vaccinated had higher odds than those vaccinated (OR 2.883). Taken together, age, religion, province of residence, COVID-19 vaccination status, and perceived risk due to COVID-19 played a role in determining the prevalence of generalized anxiety disorder among students.
广泛性焦虑障碍(GAD)是疾病暴发期间常见但紧迫的心理健康问题。随着第二波疫情的爆发,教育机构关闭,学生只能在网上学习[1],这可能会产生许多心理问题。本研究旨在评估新冠肺炎导致的大学生广泛性焦虑障碍的患病率。对176名在中央教育系就读的大学生进行了横断面在线调查,回复率为76.5%。采用广泛性焦虑障碍量表(GAD-7)对焦虑障碍进行评估。使用简单的随机抽样技术选择学生,并将在Kobo工具箱中创建的问卷链接发送给他们,要求他们自愿参与。使用描述性统计和多元逻辑回归分析收集到的回复,以找出广域网焦虑症的患病率和相关因素。一项研究发现,47.7%的大学生因新冠肺炎而患有广泛性焦虑症。与30岁以下的参与者相比,年龄较大的参与者患焦虑症的可能性较低(OR 0.267)。佛教徒的概率高于印度教徒(OR 5.237),巴格玛提省和蓝毗尼省的学生的概率高于克希省(OR分别为8.116和6.086)。未感染的学生出现焦虑障碍的几率高于感染的学生(OR为7.564),未接种疫苗的学生出现焦虑障碍的几率高于接种疫苗的学生(OR为2.883)。综合考虑,年龄、宗教、居住省份、COVID-19疫苗接种状况以及因COVID-19引起的感知风险在决定学生广泛性焦虑症的患病率方面发挥了作用。

यो लेख बौद्ध परम्परा सम्बन्धि एक कार्यशाला गोष्ठीमा सहभागी हुँदा प्रशिक्षकले प्रस्तुत गरिएका विचार तथा उच्चारित पाण्डुलिपि तथा लेखका आधारमा तयार पारिएको हो। यो लेखको उद्देश्य हामीले पाए र वुझेजति पाठकलाई बुझाउने तथा बुझाइमा फरक परको भए सुझाव तथा सल्लाह लिई परिष्कुत लेख तयार पार्नु नै हो । यसमा बुद्ध धर्मको परिचय, गौतम बुद्धको पवित्र जन्मस्थलः लुम्बिनी, बौद्ध धर्मका सम्प्रदायहरूः हियान/हिनयान वा थेरवाद, महायान वज्रयानमहायानको उपशाखा, नाथ परम्परा अवलोकितेश्वर, थेरवाद र महायानबीचको भिन्नता, चौथो अन्तर्राष्ट्रिय बौद्ध सम्मेलन (१५–२१ नोभेम्बर १९५६) काठमाडा,ैभारतका संविधान निर्माता बाबा साहेव डा. भिमराव अम्बेडकरको नेपाल भ्रमण, नेपालमा थेरवाद र छलफल सहितको निष्कर्श निकालिएको छ । प्राप्त लेख तथा पाण्डुलिपिका अनुसार बुद्ध लुम्बिनिमै जन्मे पनि समग्र नेपालमा यसको प्रभाव पछि मात्र परेको देखिन्छ । नेपालमा सनातनी हिन्दू पछि बुद्ध धर्मको प्रचार बढेसँगै बुद्धको महापरिनिर्माण पछि मात्रै हिन्दूहरुनै महायानी बज्रायानी भएको र प्रवजित भएको देखिन्छ । अहिले पनि अधिकांश नेपाली बौद्धहरु सनातनि तथा प्रकृति पूजा निकट सांसारिक जीवन पद्धति अंगालेको देखिन्छ । यस धर्मका अनुसार जसले ज्ञान प्राप्तिपछि अरूलाई पनि बाँड्छन्, तिनिहरुलाई बुद्ध भनिन्छ, ज्ञान प्राप्त गर्छन् तर अरूलाई बाँडदैनन् भने तिनिहरुलाई प्रत्येकबुद्ध तथा ज्ञान प्राप्त गरेर पूर्णतया उपयोग गर्छन् भने तिनिहरुलाई अर्हत भनिन्छ । यसैका आधारमा पहिलोलाई हिनायान, दोश्रोलाई महायान तथा तेश्रोलाई बज्रयानी भनिएको छ । बज्रयानी भित्रै अवलोकितेश्वर तथा नाथ परम्परा रहेको पनि दाबि गरिन्छ जो शिव भगवानसँग नजिक मानिन्छन् । नेपालमा हिनायान राणाकालको अन्त्यतिर मात्रै चर्चाका आयो । त्यसपछिका सरकार तथा पश्चिमाहरुले हिनायान वा थेरबादलाई प्राथमिकतामा राखेको देखिन्छ । नेपालमा सनातनि पूर्वीय सभ्यतामा दोश्रो शताब्दीतिरबाट थपिएको यो यानी सभ्यतालाई जोगाई नेपाललाई सनातनी हिन्दू तथा बौद्घ सभ्यताको केन्द्र बनाउनु पर्ने देखिन्छ । समग्रमा बुद्धको ज्ञानलाई धर्म, सम्प्रदायमा मात्र सिमित नराखि जिवनपद्धतिमैढाल्न महायानी परम्परालाई अगाडि बढाउनु पर्ने देखिन्छ ।
