    Environmental Aid and Economic Development in the Third World

    Climate change has a profound impact on the planet, especially on developing countries – as highlighted by the Stern Report to the British government in 2006. One solution to mitigating environmental degradation and achieving better outcomes appears to be through the provision of aid to poor countries. Using newly available data from the PLAID (Project-Level Aid) database project, we ask what determines the level of environmental aid to developing countries – and in particular whether such aid is affected by the level of economic development of the recipient country. At the same time, we investigate whether economic development is affected by the receipt of environmental aid. Implicit in the second question, of course, is the notion that, besides addressing the ecological outcomes, environmental aid may have the potential to enhance the economic prosperity of poor countries.Economic Development; Aid; Developing Countries

    The aim of research was to produce valid, practical and had potential-effect to mathematic literacy ability in PISA like mathematics problem in using row sports context at Asian Games 2018. The research method used development research with development studies type. The subjects of the research were the students with 15 years old of class X SMAN 10 Palembang. The techniques of collecting data were used documentation, walkthrough, test, and interview. This research produced the problem about how the students determined how many benches could be made by only knowing length and width of the boats. The results showed that the problem developed (1) valid from the suitability with the framework PISA regarding content, context, literacy process and level of questions that was connected problems with daily life accordance experts review and one to one stage (2) practical because the problem could be understood by students accordance small group stage, and (3) had a potential effect from the result of analyze the student's answer in mathematical literacy ability with representation and reasoning ability as dominant accordance field test stage

    A Study of Corrosion Behaviour for Steels Precipitated with Paraffin Wax Precipitation

    Paraffin wax and CO2 corrosion have caused many problems in oil and gas industry. These problems mainly caused in the transportation and utilities where the pipelines are severely corroded. Adding to this situation paraffin wax deposition causing blockage which results flow assurance. Many experiments have been conducted individually on finding the factors that cause corrosion and factors causing wax precipitation. Only a few research relating both the problems together. In this research, the objective is to design and develop apparatus to produce wax onto a steel surface in laboratory environment and to determine the effect of paraffin wax precipitation on the corrosion of steel. In order to complete these objective, wax appearance temperature (WAT) was determine in order to precipitate 1.5mm thick 10% and 30% paraffin wax on the APL 5L X65 steel. Modified cold spot test was designed in order to precipitate paraffin wax on 24oC X65 steel for 24 hours. Before conducting the Linear Polarization Resistance (LPR) experiment for the precipitated samples, a baseline test was conducted using three electrode system in a glass cell to identify the corrosion rate of X65 carbon steel in the 3% NaCl purged with CO2 under room temperature without any precipitation

    Roles of estrogen receptor-alpha in mediating life span: the hypothalamic deregulation hypothesis.

    In several species caloric restriction (CR) extends life span. In this paper we integrate data from studies on CR and other sources to articulate the hypothalamic deregulation hypothesis by which estrogen receptor-alpha (ER-α) signaling in the hypothalamus and limbic system affects life span under the stress of CR in mammals. ER-α is one of two principal estrogen-binding receptors differentially expressed in the amygdala, hippocampus, and several key hypothalamic nuclei: the arcuate nucleus (ARN), preoptic area (POA), ventromedial nucleus (VMN), antero ventral periventricular nucleus (AVPV), paraventricular nucleus (PVN), supraoptic nucleus (SON), and suprachiasmatic nucleus (SCN). Estradiol signaling via ER-α is essential in basal level functioning of reproductive cycle, sexually receptive behaviors, physiological stress responses, as well as sleep cycle, and other nonsexual behaviors. When an organism is placed under long-term CR, which introduces an external stress to this ER-α signaling, the reduction of ER-α expression is attenuated over time in the hypothalamus. This review paper seeks to characterize the downstream effects of ER-α in the hypothalamus and limbic system that affect normal endocrine functioning

    Autonomous mobile robot teams

    Get PDF
    This paper describes autonomous mobile robot teams performing tasks in unstructured environments. The behavior and the intelligence of the group is distributed, and the system does not include a central command base or leader. The novel concept of the Tropism-Based Cognitive Architecture is introduced, which is used by the robots in order to produce behavior transforming their sensory information to proper action. The results of a number of simulation experiments are presented. These experiments include worlds where the robot teams must locate, decompose, and gather objects, and defend themselves against hostile predators, while navigating around stationary and mobile obstacles

    The Inter-Mammary Sticky Roll: A Novel Technique for Securing a Doppler Ultrasonic Probe to the Precordium for Venous Air Embolism Detection.

    Get PDF
    Venous air embolism is a devastating and potentially life-threatening complication that can occur during neurosurgical procedures. We report the development and use of the "inter-mammary sticky roll," a technique to reliably secure a precordial Doppler ultrasonic probe to the chest wall during neurosurgical cases that require lateral decubitus positioning. We have found that this noninvasive technique is safe, and effectively facilitates a constant Doppler signal with no additional risk to the patient

    Fruit and Vegetable Bucks: Adams County Grocery Store Snap Incentive Program

    Full text link
    Veggie Bucks provides a 50% discount on all fresh fruits and vegetables sold through Kennie’s Market produce department at the point of sale for the 5 highest cost items. The incentive period ran January - April, 2017. Intended outcomes include an increase in the number of fresh fruits and vegetables purchased by SNAP recipients at Kennie’s Market locations in Biglerville and Gettysburg by 10% in January-April 2017 compared to baseline figures obtained in 2016, and to familiarize SNAP recipients with fresh fruits and vegetables and to provide information about the ACFMA markets’ Double Dollars program. SNAP recipients were invited to sign up for the program upon showing their ID and EBT card and were provided a Kennie\u27s Frequent Shopper card if they did not have one already
