Comparative Investigation for Energy Consumption of Different Chipsets Based on Scheduling for Wireless Sensor Networks

Rapid progress in microelectromechanical system (MEMS) and radio frequency (RF) design has enabled the development of low-power, inexpensive, and network-enabled microsensors. These sensor nodes are capable of capturing various physical information, such as temperature, pressure, motion of an object, etc as well as mapping such physical characteristics of the environment to quantitative measurements. A typical wireless sensor network (WSN) consists of hundreds to thousands of such sensor nodes linked by a wireless medium. In this paper, we present a comparative investigation of energy consumption for few commercially available chipsets such as TR1001, CC1000 and CC1010 based on different scheduling methods for two types of deployment strategies. We conducted our experiment within the OMNeT++ simulator.Comment: 17 pages, Based on scheduling for Wireless Sensor Network

PET radiopharmaceuticals for imaging chemotherapy-induced cardiotoxicity

PURPOSE OF REVIEW: Currently, cardiotoxicity is monitored through echocardiography or multigated acquisition scanning and is defined as 10% or higher LVEF reduction. The latter stage may represent irreversible myocardium injury and limits modification of therapeutic paradigms at earliest stages. To stratify patients for anthracycline-related heart failure, highly sensitive and molecularly specific probes capable of interrogating cardiac damage at the subcellular levels have been sought. RECENT FINDINGS: PET tracers may provide noninvasive assessment of earliest changes within myocardium. These tracers are at nascent stages of development and belong primarily to (a) mitochondrial potential-targeted and (b) general ROS (reactive oxygen species)-targeted radiotracers. Given that electrochemical gradient changes at the mitochondrial membrane represent an upstream, and earliest event before triggering the production of the ROS and caspase activity in a biochemical cascade, the former category might offer interrogation of cardiotoxicity at earliest stages exemplified by PET imaging, usin

Post-placental postpartum intrauterine contraceptive devices insertion: our scenario

Background: India is the second most populous country in the world with a population estimate of 1,304,162,999 on 1st January 2016. Population explosion is a great menace for the country and effective population control is the need of the hour. This study was designed to evaluate postpartum intrauterine contraceptive devices (PPIUCD), which is a novel innovation in population control.Methods: This was a prospective study with a sample size of 300 women (150 cesarean and 150 vaginal deliveries). After informed consent and assessing eligibility for PPIUCD, Cu-T 380A was inserted. Post-insertion, the cases were followed up to 12 weeks after delivery with special attention to acceptance and complications like IUCD expulsion, hemorrhage, pelvic pain and infection. The results were compiled and statistically analyzed.Results: Acceptance of PPIUCD was higher in Cesarean deliveries than in vaginal deliveries. Acceptance was also higher in unplanned pregnancies. Presence of prior male child influenced decisions. Minor complications were reported but there were no serious complications. No expulsions were reported in post-cesarean cases.Conclusions: PPIUCD, a long-acting reversible method of contraception, is a safe option with high retention rate and very few expulsions and side effects. There was higher rate of acceptance, no expulsion and high continuation rate in post-cesarean cases as compared to vaginally delivered cases

ATRA Induced Reactive Hemophagocytosis: a Case Report

All trans-retinoic acid (ATRA) is a targeted therapy, used in Acute Promyelcytic leukemia (APL) and causes the abnormal promyelocytes to differentiate in to mature leucocytes, however their clearance in vivo is not known. ATRA has been found to be associated with hemophagocytosis, but sometimes one may find phagocytosis of differentiated cells by histiocytes without the overt manifestations of hemophagocytic syndrome. We report a case of APL showing differentiated cells being phagocytosed by marrow histiocytes while patient was getting ATRA therapy

Common Parasite With Uncommon Associations

Filaariasis a quite common in some parts of the world including India. It has been reported as an incidental finding in cytology smears. Here we report three cases where microfilariae of Wuchereria Bancrofti were detected incidentally in bone marrow smears, in two cases in special stain slides. All these patients were being investigated for other hematological disorders

Engineering Leadership Assessment Tool Profile

Numerous studies have been conducted stressing the importance of developing the professional skillset of engineers. This need has been further highlighted by the Engineering Criteria 2000 and by the National Academy of Engineers (Kumar and Hsiao, 2007, p. 19). Having realised the need to develop the professional skillset of engineers such as leadership, interpersonal skills, teamwork and communication, universities have started incorporating methods to hone these skills in their courses. However in today’s competitive world, every practice needs to be assessed and measured for accountability and effectiveness. Engineering education is no exception to this rule. There needs to be a tool that can assess the leadership abilities of engineering students to see if courses are meeting their desired outcomes. This led to the creation of an assessment tool that can be used by students to self-assess themselves or by faculty to gauge a students’ strengths and weaknesses. The tool reports personalised scores which can be compared with data obtained from a survey completed by 700 students to establish a baseline of leadership skills in camparison to one’s peers. The tool can also guide students in selecting courses that can strengthen areas that they are currently lacking in. The tool, once validated, can be implemented on a larger scale and even be used in other universities

Industry 4.0 technologies for manufacturing sustainability: A systematic review and future research directions

Recent developments in manufacturing processes and automation have led to the new industrial revolution termed “Industry 4.0”. Industry 4.0 can be considered as a broad domain which includes: data management, manufacturing competitiveness, production processes and efficiency. The term Industry 4.0 includes a variety of key enabling technologies i.e., cyber physical systems, Internet of Things, artificial intelligence, big data analytics and digital twins which can be considered as the major contributors to automated and digital manufacturing environments. Sustainability can be considered as the core of business strategy which is highlighted in the United Nations (UN) Sustainability 2030 agenda and includes smart manufacturing, energy efficient buildings and low-impact industrialization. Industry 4.0 technologies help to achieve sustainability in business practices. However, very limited studies reported about the extensive reviews on these two research areas. This study uses a systematic literature review approach to find out the current research progress and future research potential of Industry 4.0 technologies to achieve manufacturing sustainability. The role and impact of different Industry 4.0 technologies for manufacturing sustainability is discussed in detail. The findings of this study provide new research scopes and future research directions in different research areas of Industry 4.0 which will be valuable for industry and academia in order to achieve manufacturing sustainability with Industry 4.0 technologies
