Since the publication of the NCTM Standards in 1989, which was followed by a new generation of curriculum development projects, the field has seen increasing interest in research on curriculum resources, how they are used by teachers and experienced by students, and the outcomes that they produce. Although some studies seek to draw direct lines between particular curriculum materials used and student outcomes, a majority of researchers argue that understanding whether and how teachers are implementing a given written curriculum resource1 with some measure of fidelity is necessary to determining its effects on learning (Stein, Remillard, & Smith, 2007). Over the last 2 decades, research has expanded to consider how teachers interpret, learn from, interact with, and generate curriculum resources. Over a similar timespan, the number and types of curriculum resources available to teachers have also expanded to include print, digital, and blended comprehensive curricula along with a slew of supplemental resources and tools available through the Internet.

he basic ideas about the process of introducing cores into protective barriers and the most common core patterns and their location in conventional and sub-caliber small arms bullets are discussed. The materials used for manufacture of cores are analyzed. It is concluded that for mass bullets of increased armor penetration the most rational choice can be considered the use of high-carbon low-alloy steels of a new generation with a natural composite structure and hardness of up to 70 HRC. For specialized armor-piercing bullets, cores made from promising economically-alloyed high-speed steels characterized by a high complex of «hardness—bending strength» are better alternative than ones made of hard alloys or tungsten alloys.

Development Costs

Complex software systems and the huge amounts of data they produce are becoming an integral part of our organizations. We are also becoming increasingly dependent on high quality software products in our everyday lives. These systems ‘evolve’ as we identify and correct existing defects, provide new functionalities, or increase their nonfunctional qualities - such as security, maintainability, performance, etc. Simultaneously, more software development projects are distributed over multiple locations (often globally) and are often several millions of dollars in development costs. Consequently, as the Internet continually eliminates geographic boundaries, the concept of doing business within a single country has given way to companies focusing on competing in an international marketplace. The digitalization of work and the reorganization of work processes across many organizations have resulted in routine and/or commodity components being outsourced.

Este trabajo aborda, de manera sintética, uno de los problemas más relevantes con los que nos estamos encontrando en el Siglo XXI resultado del fenómeno de Internet, el de las redes sociales que constituyen vías consolidadas de relación e interacción cotidianas, no sólo de las nuevas generaciones de adolescentes y jóvenes, sino también de todo el conjunto de nuestra sociedad. Y pese a que la utilización de las nuevas Tecnologías de la Información y Comunicación ofrece grandes oportunidades y ventajas, no puede obviarse igualmente que éstas nos pueden situar en la sociedad del riesgo, por cuanto que pueden entrañar múltiples peligros, entre los que cobra una especial relevancia la posibilidad de conculcación de los derechos fundamentales a la intimidad, al honor, a la propia imagen y a la protección de datos personales, bien individualmente considerados o, bien de forma conjunta, acrecentándose los citados riesgos entre jóvenes y adolescentes, en cuanto usuarios indiscriminados. Pero, a éstos se añaden además otros riesgos por conductas delictivas, como el denominado Ciberacoso.This research recollects in a synthetic way, one of the most relevant problems the society is facing today, as a consequence of the Internet phenomenon. The routes of social Networks in the daily relations and interactions are consolidating in such a way that is not only affecting the young teenagers and the new generation, but also the whole of our society. In spite of the fact that, the utilization of new Technology of Information and Communication offer great opportunities and have many advantages, however, one should not ignore that this situation is putting the society at risk. This phenomenon contains many dangers, as well as the possibility of violating the fundamental laws to intimacy, to the honor, to one’s own image and to the personal data protection, being individually considered or as a whole form in conjunction of the mentioned risks between the youth and adults users. Moreover, there will be an increase of this risk, because of criminal behaviors as Ciber bullying.

Optimum Sample

With increasing global urbanization and industrialization, many more pipelines for gas, potable water, sewer, oil, and power cables have been installed underground, underwater, in buildings and in factories. Maintenance of such pipelines is crucial. However, it is often difficult and has become a growing problem these days. The PALTEM-HL (Trade mark and stands for Pipeline Automatic Lining SysTEM, Hose Lining Method), a pipeline relining system, was developed as an effective and inexpensive solution for this problem. In this project, we try to develop a new resins and the adhesives system to replace the raw materials used in the PALTEM-HL system. Anionic harder combined two different types of epoxy resins were investigated in this study. After curing, the mechanical properties and glass transition temperature of the mixture were examined and the optimum sample preparation prescription was also found. FTIR (Fourier Transform Infrared Spectroscopy) and DSC (Differential Scanning Calorimeter) were employed to monitor the curing process of the mixtures. The mechanical properties of the mixture were also measured by Instron and micro Vickers.
