A suggested preschool program for the Woodstown-Pilesgrove Regional School District

The purpose of this study was to suggest a type of preschool curriculum that would be effective for the Woodstown-Pilesgrove School District. This was accomplished in various stages. First, library research was conducted at EIRC and the Rowan University Library to find recent literature on the various types of preschool curriculums. Then, because the needs of the community should be considered when designing a public preschool curriculum, an informal survey was designed to solicit the opinions of present and past kindergarten teachers in the Woodstown-Pilesgrove School District. The results of this narrative survey were used to design the major components of the preschool curriculum. The recommendations for the preschool program, determined through the survey, are the following: a NAEYC accredited preschool, located at the Mary S. Shoemaker School, should be publicly funded focusing on children who are at risk for school failure. Because of limited enrollment children with financial and academic need should receive priority for enrollment in the program. The preschool\u27s curriculum, while focusing on socialization, will also address kindergarten readiness skills. Children with special needs should attend, but training, consultative assistance, and additional teacher assistants should be provided by the district

Das Technology Assessment und die Sozialwissenschaften: eine Replik zur Konzeption von Heft 2/86 von SuB

Der Verfasser setzt sich kritisch mit dem Schwerpunktthema von H. 2/86 von SuB auseinander, das auf das Verhältnis von Technikfolgenabschätzung (TA) und Sozialwissenschaft einging. Die Kritik richtet sich dabei nicht gegen die Autoren der Beiträge, sondern vielmehr gegen die redaktionelle Konzeption des Heftes. Im einzelnen wendet er sich dagegen, daß die Beiträge vor allem den Diskussionsstand um die Institutionalisierung des TA in der BRD dokumentierten anstatt den möglichen Beitrag der sozialwissenschaftlichen in der Forschung zum Thema herauszuarbeiten. Weiterhin vermißte er eine Beschäftigung mit der Frage der demokratischen Legitimation von Entscheidungen in Technologiefragen ebenso wie die Formulierung berufsständischer Interessen, die in einem Fachorgan eines Berufsverbandes zu erwarten sein könnte.

Power‐to‐Gas: CO2 Methanation Concepts for SNG Production at the Engler‐Bunte‐Institut

Power-to-Gas approaches comprise different activities to store electric power in form of gaseous energy carriers like hydrogen or methane. The synthesis of SNG (substitute natural gas) and its injection into the natural gas grid allows the utilization of the well-established infrastructure for natural gas storage, distribution and utilization without the need for further changes to the energy system. At the Engler-Bunte-Institut research focuses on catalytic methanation in catalytically coated metallic honeycomb reactors and in slurry bubble column reactors with the aim of evaluating alternative reactor concepts offering optimized heat transfer characteristics as well as maximizing the possibility of dynamic operation. Both concepts are attractive for small to medium scale power-to-gas applications. Hence, a scale-up was performed for bothreactor concepts with the aim of implementation on commercial scale

Passive Solar Collector Freeze Characteristics

The major challenge for solar water heaters is to provide heat at a cost comparable to or lower than conventional fuels. Since the price of integral-collector-storage solar water heaters (ICS) is about one half to two thirds of that for active systems with freeze protection, they can provide lower-cost energy. However, ICS are subject to freeze damage, as the collector generally has metal tubes carrying pressurized water that can freeze and burst. In order to delineate the geographical areas where ICS can be deployed safely it is necessary to experimentally determine the conditions under which freeze damage occurs, to develop a model relating the freeze behavior to climatic conditions, and to validate that model with the experimental data. Three types of ICS have been subjected to increasingly severe freeze conditions, until freeze damage occurs. Tested units include double and single-glazed conventional units, and an innovative ICS with immersed metallic heat exchanger carrying pressurized water in a plastic box of stagnant, unpressurized water. Existing models for ICS thermal performance were modified to incorporate the freezing process, and have been validated with the experimental data. The validated models will be used to predict regions of the country safe for installing the ICS. Simulations will be done over at least 30 years of weather. Finally maps are created to illustrate the regions of safe installation
