    Fitness exercises with all their components have been widespread in recent years and have become largely practiced in most fitness centres as they aim to develop functional devices abilities and capabilities, which helps to speed performance, movement lightness and body agility. Most of first stage practical materials in order to be practiced demands strength, lightness and agility and since the researchers are working in the educational profession noticed a clear weakness in students’ performance for movements and their inability to perform them properly due to the noticeable increase in weight and the lack of interest in applying modern methods in education or practical application which contributed significantly to the lack of movement and performance ineffectiveness among the students. The researchers used the experimental method with one experimental group with tribal and dimensional tests because it fits the research problem nature, the research community was identified by first stage students from the Faculty of Physical Education and Sports Sciences, Wasit University deliberately, where the number of community members were 48 students, the sample was selected randomly the researchers conducted the exploratory experiment on the group, and conducted a training unit for the Pilates exercise which the researchers prepared in the curriculum for the group on the day of 1/4/2018. The researchers concluded that Pilates-exercises led to the development of body measurements among the research sample also led to a decrease in weight and thus reduced the body circumference measurements. The researchers recommended using divers training equipment and conducting training courses for trainers

Pardee Center for the Study of the Longer-Range Future.On October 27 and 28, 2009, a workshop of experts on higher education in developing countries was convened by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future. The meeting was supported by a grant from the National Academies Keck Futures Initiative with additional support from the Pardee Center and the Office of the Boston University Provost. The meeting brought together experts in economics, public policy, education, development, university management, and quantitative modeling who had rich experiences across the developing world. These experts offered a variety of conceptual tools with which to look at the particular complexities associated with higher education in developing countries. The meeting was convened by the authors of this paper. This policy brief builds upon and reflects on the discussion at this meeting, but is not a meeting report, per se

    A study was conducted to observe the effect of intramuscular injection of ovaprim-C on the number of eggs/kg, fertilization rate and hatching percentage at a private fish hatchery and research center at Faisalabad, Pakistan, during May to June 2008, on Labeo rohita (Rohu). Studied fish specimens were spawned successfully following a single dose of injection of ovaprim-C (LH-RH analogue) with 0.4 ml kg-1 for female and 0.05 ml kg-1 for male brooders. Ova and milt were stripped simultaneously and mixture was stirred for 15 to 30 s during which fertilization occurred. Hatching occurred within 18 to 30 h after fertilization. The experiment was conducted in circular spawning tank with 2 m diameter. If it is impossible to determine the absolute and relative fecundity, then these parameters can be determined from the body weight. Average number of eggs/kg, fertilized eggs/kg and hatchlings/kg was 63574, 49067 and 39952, respectively. Overall fertilization and hatchling %age was 77.50% and 81.39% respectively. Wet body weight was observed to have a positive influence on absolute (r=0.983) and relative fecundity (r = 0.910) in log-log scale.Keywords: Induced spawning, ovaprim-C, fecundity, Labeo rohita.African Journal of Biotechnology Vol. 12(19), pp. 2722-272

    Get PDF
    RFID (Radio Frequency Identification) is one of the most growing technologies among the pervasive systems. Non line of sight capability makes RFID systems much faster than its other contending systems such as barcodes and magnetic taps etc. But there are some allied security apprehensions with RFID systems. RFID security has been acquired a lot of attention in last few years as evinced by the large number of publications (over 3000). In this paper, a brief survey of eminent ultralightweight authentication protocols has been presented & then a four-layer security model, which comprises of various passive and active attacks, has been proposed. Finally, Cryptanalysis of these protocols has also been performed under the implications of the proposed security model

    Pitfalls in Ultralightweight RFID Authentication Protocol

    Radio frequency identification (RFID) is one of the most promising identification schemes in the field of pervasive systems. Non-line of sight capability makes RFID systems more protuberant than its contended systems. Since the RFID systems incorporate wireless medium, so there are some allied security threats and apprehensions from malicious adversaries. In order to make the system reliable and secure, numerous researchers have proposed ultralightweight mutual authentication protocols; which involve only simple bitwise logical operations (AND, XOR & OR etc.) to provide security. In this paper, we have analyzed the security vulnerabilities of state of the art ultralightweight RFID authentication protocol: RAPP. We have proposed three attacks (two DoS and one Desynchronization) in RAPP protocol and challenged its security claims.  Moreover, we have also highlighted some common pitfalls in ultralightweight authentication protocol designs. This will help as a sanity check, improve and longevity of ultralightweight authentication protocol designs

    A Caucasian man in early 80s was seen in Gastroenterology Clinic, following, referral from the Endocrinology Clinic for concerns for CT Abdomen requested for tiredness and weight loss of three kilograms. The patient also had microcytic picture with low MCV and Ferritin and hypomagnesemia. The CT suggested gross circumferential thickening of the wall of stomach with advice for invasive investigations to further characterise the CT findings. The Endoscopy suggested grossly enlarged rugae in the stomach, and enlarged gastric polyps. Patient was assured no new sinister abnormality. Treatment challenges to consider were to stop acid suppression by prescribing Proton Pump Inhibitors (PPIs) which would lead to stomach ulcers, or to continue with PPIs with sequalae of worsening of hypertrophic gastric folds, enlarged gastric polyps and hypomagnesemia. It would be necessary to consider risk versus benefits in either situation to determine an appropriate treatment plan in the long term. With background of Zollinger-Ellison Syndrome and MEN1 with heterozygous mutation with gastrinoma of the duodenum, and frailty he was advised to continue with Proton Pump Inhibitors with twice weekly correction of Magnesium infusions, and Iron tablets following Multi-disciplinary meeting

    Asynchronous Communication under Reliable and Unreliable Network Topologies in Distributed Multiagent Systems: A Robust Technique for Computing Average Consensus

    Get PDF
    Nearly all applications in multiagent systems demand precision, robustness, consistency, and rapid convergence in designing of distributed consensus algorithms. Keeping this thing in our sight, this research suggests a robust consensus protocol for distributed multiagent networks, continuing asynchronous communications, where agent’s states values are updated at diverse interval of time. This paper presents an asynchronous communication for both reliable and unreliable network topologies. The primary goal is to delineate local control inputs to attain time synchronization by processing the update information received by the agents associated in a communication topology. Additionally in order to accomplish the robust convergence, modelling of convergence analysis is conceded by commissioning the basic principles of graph and matrix theory alongside the suitable lemmas. Moreover, statistical examples presenting four diverse scenarios are provided in the end; produced results are the recognisable indicator to authenticate the robust effectiveness of the proposed algorithm. Likewise, a simulation comparison of the projected algorithm with the other existing approaches is conducted, considering different performance parameters are being carried out to support our claim

    Parental Effects on Primary School Enrolment under Different Types of Household Headship: Evidence from Pakistan

    Get PDF
    Previous studies in Pakistan have established the number of pupil, parents, household, and community characteristics as determinants of primary school enrolment. However, treatment of the role of the household power structure in these studies is limited to the inclusion of a single dummy variable for female headship. Present study estimates separate probit regressions for different types of headships, hence allowing for an analysis of the power structure of the household and its impact on other explanatory variables. In addition to confirming the findings of previous studies, this study concludes that mother‘s headship results in greater positive influence of her own education and the economic status of the household on child‘s primary school enrolment. Father‘s headship in this regard has only limited influence. JEL Classification: C25, J16, I21 Keywords: Probit Models, School Enrolment, Gender Issue
