The focus of this work was on experimental measurements and numerical computations of Pimelic acid solubility in water, ethanol, and their binary combination. At temperatures ranging from (293.15 to 303.15) K, the solubility of Pimelic acid in pure solvents and their binary mixtures was evaluated using the equilibrium measurement method. To evaluate the data quality, the experimental results were correlated to the Apelblat equation. The Apelblat model's solubility correlations were in good accord with experimental data.

A study was conducted to investigate the effect of leaf litterfall of shelterbelt, Azadirachta indica, Ailanthus excels and Prosopis cineraria and control (devoid of trees) on available nutrients and organic carbon pools of soil from 3 distances (2, 5 and 10m) The total litterfall during the study period ranged between 1712 and 4126kg/ha and it was found maximum in the month of January and it was minimum in February in different plantations. Annual litterfall showed considerable variation among different plantations. Litter accumulation under the different plantations canopy was highest in the shelterbelt followed by Prosopis cineraria and lowest in the Azadirachta indica. There was improvement in soil organic carbon, dissolved organic carbon, microbial biomass carbon, available macro (N, P and K) and micronutrients (Zn, Fe, Mn and Cu) tree species when compared to field without trees. Significant improvement in soil organic carbon (0.14 to 0.26 %), available N (55.9 to 116.6kg/ha) P (9.6 to 13.6kg/ha) and K (188.9 to 248.3kg/ha) was observed under these tree species compared to field without trees. The content of Zn, Cu, Fe and Mn and was 15, 25, 40 and 51 percent, respectively higher under these tree species than the control field. The amount of nutrients returned to the soils through litter was significantly highest at 2m distance under different plantations. The present study indicated that these available nutrients and organic carbon pools improved significantly across the different land use system. Due to intensive cultivation and monocropping, the fertility of soil is deteriorating day by day. Simultaneously it is creating a pressure on the natural resources like soil because the population is increasing day by day. Therefore, it is wise to use degraded and problematic soil for cultivation. Agroforestry systems have been recognized as an alternative for the rehabilitation of degraded areas and it provides ecosystem services and reduces human impacts on natural forests (Nair et al., 2009). Tree based land use systems have special role in reclamation of wastelands, use of poor-quality waters, organic carbon build up and moderating climate change related risks. In areas of Haryana and Rajasthan trees like Prosopis cineraria, Azadirachta indica and Ailanthus excels are more beneficial under adverse environments due to their drought hardiness, resistance to inhospitable climate and assured economic returns. These tree species can be grown on soils having poor fertility, moisture deficit and high soil temperature.
在2、5、10m的距离上,研究了不同林分、印度楝、大Ailanthus和无树对照对土壤速效养分和有机碳库的影响。研究期间,不同林分的凋落物总量在1712 ~ 4126kg/ha之间,1月最大,2月最小。不同人工林的年凋落物量差异较大。不同人工林林冠下的凋落物积累量以林带最高,其次是木杉,最低的是印楝。土壤有机碳、溶解有机碳、微生物生物量碳、速效宏量元素(N、P、K)和微量元素(Zn、Fe、Mn、Cu)均有明显改善。土壤有机碳(0.14% ~ 0.26%)、速效氮(55.9 ~ 116.6kg/ hm2)、磷(9.6 ~ 13.6kg/ hm2)和钾(188.9 ~ 248.3kg/ hm2)均显著高于裸地。这些树种的Zn、Cu、Fe和Mn的含量分别比对照地高15%、25%、40%和51%。不同人工林通过凋落物返回土壤的养分量在2m距离处显著最高。研究表明,在不同的土地利用系统中,速效养分和有机碳库均有显著改善。由于精耕细作和单作,土壤肥力日益恶化。同时,由于人口日益增加,它给土壤等自然资源造成了压力。因此,使用退化和有问题的土壤进行种植是明智的。农林复合系统已被认为是恢复退化地区的另一种选择,它提供生态系统服务并减少人类对天然林的影响(Nair等人,2009)。以树木为基础的土地利用系统在荒地复垦、劣质水利用、有机碳积累和减缓气候变化相关风险方面具有特殊作用。在哈里亚纳邦和拉贾斯坦邦地区,像Prosopis cineraria, Azadirachta indica和Ailanthus excels这样的树木在恶劣环境下更有利,因为它们具有抗旱性,对恶劣气候的抵抗力和经济回报的保证。这些树种可以生长在肥力差、水分不足和土壤温度高的土壤上。

The medicinal plants are important source for pharmaceutical manufacturing. Medicinal plants & herbal medicines account for a significant percentage of the pharmaceutical market. There is increasing awareness and general acceptability of the use of herbal drugs in today’s medical practice although most of these applications are not scientific. Herbal medicines are not a simple task since many factors influence the biological efficacy and Reproducible therapeutic effect. So it is necessary to improve safety of herbal drugs by developing certain quality control parameters and by following the WHO guidelines for herbal medicine WHO specific criteria for assessing the safety, efficacy, and quality of herbal medicines are critical for global harmonisation. The term “standardisation” refers to the assurance of a drug’s identification, quality, and purity at all stages of its life cycle. This study examines the need for and breadth of herbal medicine standardisation techniques for optimal quality assurance.To provide a platform for the quality control of traditional herbal medicines and to discover novel therapeutics composed of multiple chemical compounds, it is necessary to combine chemistry, pharmacology, medicine, and even statistics.
药用植物是医药生产的重要原料。药用植物和草药占医药市场的很大比例。在今天的医疗实践中,尽管大多数草药的应用并不科学,但人们对草药的认识和接受程度越来越高。草药治疗不是一项简单的工作,因为许多因素影响着草药的生物功效和可重复性治疗效果。因此,有必要通过制定某些质量控制参数和遵循世卫组织草药指南来提高草药的安全性。世卫组织评估草药安全性、有效性和质量的具体标准对于全球协调至关重要。术语“标准化”是指药品在其生命周期的所有阶段的鉴定、质量和纯度的保证。本研究探讨了草药标准化技术对最佳质量保证的必要性和广度。要为中药的质量控制提供一个平台,发现由多种化合物组成的新疗法,必须将化学、药理学、医学甚至统计学结合起来。

Nursing is dynamic by its own way and this dynamism give rise to various trends. Sound empirical knowledge is the base of nursing as in any other profession. This knowledge is the base for all the innovations which in turn evolve as trends in nursing. The trends in nursing education are the cornerstone for the dynamic nature of nursing profession. The article outlines various trends in nursing education with reference to India. Thus, the software can be seen as part of an abstract rationality, whereas how it is deployed by nurses is based on a practical rationality that places practice and experience first and sees the technology and protocols as tools.

RETT Syndrome: A Case Report RETT综合征1例报告
Pub Date : 2022-08-05 DOI: 10.52711/2349-2988.2022.00026
Minnu Elizabeth Michael, Joslin John
Many childhood diseases are diagnosed a couple of years after birth. This article presents a similar condition resulting in regression and slowing down of brain growth after a normal course of development during neonatal period. Rett syndrome is such a condition that presents itself after some months of apparently normal development. This disease is usually manifested with deceleration of head growth, loss of purposeful hand movements which are replaced by hand wringing or handwashing stereotypes. This is also followed by marked mental retardation with severe impairment in expressive and receptive language skills. The child presented in this case report had a normal development till 18 months of age after which she developed delay in gross motor development and further in other areas of development. The child is now on symptomatic treatment and presents with recurrent respiratory tract infections which require hospitalization.
许多儿童疾病在出生几年后才被诊断出来。这篇文章提出了一个类似的条件,导致回归和缓慢的大脑生长后,在新生儿期正常的发展过程。Rett综合征是一种经过几个月的明显正常发育后才出现的病症。这种疾病通常表现为头部生长减速,失去有目的的手部运动,取而代之的是拧手或洗手的刻板印象。随之而来的是明显的智力迟钝,表达和接受语言技能严重受损。本病例报告中的儿童在18个月前发育正常,但在大肌肉运动发育和其他领域的发育方面出现延迟。该儿童目前正在接受对症治疗,并出现复发性呼吸道感染,需要住院治疗。

Gymnema sylvestre (Gs) is a well proven anti diabetic plant and used in Indian system of medicine for long period. A new variant of Gs was identified having hairy leaf. This Gs hairy variant species was subjected for pharmacognostical studies and screened for phytochemical analysis and correlated with the previous work done normal non hairy species. The leaves were analyzed for macroscopic and microscopic characteristics by taking microtome sectioning and stained for viewing in slides. The dried powdered leaf was subjected to fluorescent study using chemical reagents and viewed under visible and UV light to study the coloring pattern of the powdered particles interacting with the reagents. The powder was subjected for physicochemical studies using Indian Ayurvedic Pharamacopoeia procedure. The different extractions were done by using 100%, 50% ethanol and water. These extracts were subjected for preliminary qualitative analysis, quantitative estimation of terpenoides, alkaloids and marker compound Glycemnic acid.

The establishment and development of new pathogenic races is a constant problem, because chemical pest control is both expensive and ineffectual. Nanomaterials have lately been proposed as a potential alternative for reducing plant diseases and crop protection. Agricultural methods usually include the systematic administration of a variety of active chemicals at varied dosages and frequency, resulting in a variety of selective regimes. Crop protection is critical in the production of food all over the world. Nanotechnologies are being employed more and more to maintain traditional crops and to develop novel crops with superior qualities. Pollen magnetofection and gene nanocarriers are two nanobiotechnologies that are now being used to improve pest, weed, and disease management, as well as agricultural genetic modification. Traditional crop pest, weed, and disease management has been greatly enhanced thanks to a better understanding of the synthesis of nanomaterials with extraordinary capabilities. Plant germination, growth, and crop protection have all been proved to benefit from nanoparticles in agriculture. The enhanced specific surface area of nanomaterials benefits fertilisers and insecticides. Nanomaterials have also been developed for a variety of applications such as medical, medication delivery, electronics, fuel cells, solar cells, food, space, and so on. This chapter outlines recent attempts the use of nanotechnologies in agriculture in novel ways that could assist meet rising food demand while also ensuring environmental sustainability.
建立和发展新的致病小种是一个长期存在的问题,因为化学害虫防治既昂贵又无效。纳米材料最近被提出作为减少植物病害和作物保护的潜在替代方案。农业方法通常包括以不同剂量和频率系统地施用各种活性化学品,从而产生各种选择性制度。作物保护对全世界的粮食生产都至关重要。纳米技术越来越多地应用于维护传统作物和培育具有优良品质的新型作物。花粉磁感染和基因纳米载体是两种纳米生物技术,目前正被用于改善病虫害、杂草和疾病管理,以及农业基因改造。由于对纳米材料的合成有了更好的了解,传统的作物病虫害、杂草和疾病管理得到了极大的加强。植物的发芽、生长和作物保护都已被证明受益于纳米粒子在农业中的应用。纳米材料增强的比表面积有利于肥料和杀虫剂。纳米材料也被开发用于各种应用,如医疗、药物输送、电子、燃料电池、太阳能电池、食品、空间等。本章概述了最近在农业中以新颖的方式使用纳米技术的尝试,这些方法可以帮助满足不断增长的粮食需求,同时确保环境的可持续性。
