The aim of the present study was to examine changes in blood pressure among an adult woman with age. Hypertension is a major contributor to morbidity and mortality worldwide and is widespread in older women. Hypertension is one of the major risk factors associated with cardiovascular disease and is also a component of the metabolic syndrome. A total of 2,000 women classified in four age groups were examined: 20-30, 31-40, 41-50 and 51-60 years. Blood pressure was measured with a sphygmomanometer and a stethoscope (either electronically or directly into the arteries). In this study, we found that hypertension is a more common problem in women with increasing age. It affects all age groups, but the most vulnerable group was between 51 and 60 years old.
本研究的目的是研究成年女性随着年龄的增长血压的变化。高血压是全世界发病率和死亡率的主要原因,在老年妇女中普遍存在。高血压是与心血管疾病相关的主要危险因素之一,也是代谢综合征的一个组成部分。共有2000名女性被分为四个年龄组:20-30岁、31-40岁、41-50岁和51-60岁。用血压计和听诊器(电子或直接插入动脉)测量血压。在这项研究中,我们发现随着年龄的增长,高血压在女性中更为常见。它影响所有年龄组,但最脆弱的群体是51至60岁。

A QoS-Aware Multipath Routing Protocol for Wi-Fi Based Long Distance Mesh Networks 基于Wi-Fi的远距离网状网络的qos感知多路径路由协议

Routing plays a crucial role in provisioning Quality of Service (QoS) over WiFi-based Long Distance (WiLD) mesh networks. Traditional routing protocols normally maintain a single optimal path between each pair of source and destination nodes. In gateway-based mesh networks, the optimal paths between gateway and other nodes often overlap and hence degrades the overall network performance significantly. Multipath routing protocols are widely used in Wireless Mess Networks (WMN) for providing QoS to various network applications. Smooth routing of real time traffic with varying QoS requirements is a challenging task. In this paper, we propose a QoS-aware hybrid multipath routing protocol which can discover multiple maximally disjoint paths between a gateway and any other node. The gateway node selects n-best paths for the source node. Before starting a given real time flow, a path selection scheme chooses the appropriate path or set of paths amongst the available discovered paths. To evenly distribute the traffic among the paths chosen, an admission control mechanism has been proposed. In case of significant change in the quality of any discovered paths, a path maintenance process induces the source node to trigger a route update process. The proposed protocol enhances the performance of real time traffic significantly. The simulation results show that the proposed protocol achieves significant improvement in different QoS parameters. With the increase in number of disjoint paths from source to destination, a substantial improvement in throughput and delay is observed.
路由在提供基于wifi的长距离(WiLD)网状网络的服务质量(QoS)方面起着至关重要的作用。传统的路由协议通常在每对源节点和目的节点之间保持一条最优路径。在基于网关的网状网络中,网关与其他节点之间的最优路径经常重叠,从而严重降低了网络的整体性能。多路径路由协议广泛应用于无线混沌网络(WMN),为各种网络应用提供服务质量(QoS)。具有不同QoS需求的实时流量的平滑路由是一项具有挑战性的任务。在本文中,我们提出了一种qos感知的混合多路径路由协议,该协议可以发现网关和任何其他节点之间的多条最大不相交路径。网关节点为源节点选择n条最优路径。在开始给定的实时流之前,路径选择方案在可用的已发现路径中选择适当的路径或路径集。为了在选择的路径中均匀分配流量,提出了一种允许控制机制。当发现的路径质量发生重大变化时,路径维护过程诱导源节点触发路由更新过程。该协议显著提高了实时流量的性能。仿真结果表明,该协议在不同的QoS参数下都取得了显著的改进。随着从源到目的的不相交路径数量的增加,吞吐量和延迟有了实质性的改善。

In casting industry the selection of mold material and molding method is challenging task. There are several types of molding methods, but over 70% of all metal castings are generally developed by means of sand molding (sand casting). Sand casting has two processes such as, green sand casting and chemically bonded sand casting process. This paper focuses on chemically bonded sand casting i.e. no-bake sand system (self-hardening system), among from all types of no-bake sand system, alkaline phenolic ester cured (ALPHASET) and furan acid cured no-bake system are preferably discussed. Curing mechanism of all type of no-bake systems are shown along with detailing about ALPHASET and furan no-bake sand system.

Glaciers plays a major role in the generation of stream flows in Himalayan region. The Historical studies say that many glaciers in the Himalayan region are retreating due to climate change and global warming. It is important to study of glacier as they are the main source of fresh water. Due to change of climate over different time periods there is a continuous decrease of glacier areas. So it is now a days become very big issue for our future as well as present generation for fluctuation of fresh drinking water storage. The present study focuses to examine the changes in snow-covered area and glacier mass balance of the Bara Shigri glacier of Himalayan region using Remote Sensing and GIS technology. Remote sensing technique can be used without any restrictions of manual approach. The study aim is to show the changes of snow cover area and mass balance of glacier during last 27 years from 1989 to 2016. Snow cover area has been monitored using imageries of Landsat-2 and Landsat-5 multispectral band (1989, 2002, 2008, and 2016) TM and ETM data using NDSI (Normalized Difference Snow Index), NDSI-2(Normalized Difference Snow Index-2), NDGI (Normalized Difference Glacier Index), and Band ratio techniques. WGMS (World Glacier Monitoring Services) data are used for accuracy assessment for the Mass balance, front variation and annual thickness in the glacier for analyzing the surface – atmosphere interaction which contributes to melting of the glacier.
冰川在喜马拉雅地区河流的形成中起着重要作用。历史研究表明,由于气候变化和全球变暖,喜马拉雅地区的许多冰川正在退缩。冰川是淡水的主要来源,对其进行研究具有重要意义。由于不同时期气候的变化,冰川面积不断减少。因此,对于我们的未来以及我们这一代人来说,淡水储存的波动是一个非常大的问题。利用遥感和GIS技术,对喜马拉雅地区原日里冰川的积雪面积和冰川物质平衡变化进行了研究。遥感技术可以不受人工方法的限制而使用。研究目的是展示1989 - 2016年27年间冰川积雪面积和物质平衡的变化。利用Landsat-2和Landsat-5多光谱波段(1989、2002、2008和2016)TM和ETM数据,采用归一化差雪指数(NDSI)、归一化差雪指数-2、归一化差冰川指数(NDGI)和波段比技术对积雪面积进行监测。利用WGMS (World Glacier Monitoring Services)数据对冰川的物质平衡、锋面变化和年厚度进行了精度评估,分析了导致冰川融化的地表-大气相互作用。

The Historical studies say that many glaciers in the Himalayan region are retreating due to climate change and global warming. It is important to study of glacier as they are the main source of fresh water. Due to change of climate over different time periods there is a continuous decrease of glacier areas. So it is now a days become very big issue for our future as well as present generation for fluctuation of fresh drinking water storage. The present study focuses to examine the changes in snow-covered area and glacier mass balance of the Bara Shigri glacier of Himalayan region using Remote Sensing and GIS technology. Remote sensing technique can be used without any restrictions of manual approach.
