The purpose of the present paper is to compare three levels of discourse on the subject of the 21st century family. The macro scale is represented by the ideas of the International Year of the Family + 20, the meso scale – by the postulates of the government of Poland aimed at the implementation of international presumptions in Poland. The reality experienced by single parents and its inherent evaluation of the realization of the government’s postulates constitutes the micro scale. Comparison of the three perspectives allows for a discernment of the shortcomings of the government’s postulates as well as the somewhat superficial character of the undertaken actions.

Dry fiber placement has a large potential for manufacturing preforms for primary-load components at minimum scrap rate and fiber crimp. Yet, challenging impregnation behavior due to low permeability of these preforms during liquid composite molding imposes a need for further research to optimize preform structure for higher permeability. For full understanding of flow behavior within these preforms, flow has to be considered on micro scale (in between single fibers), on meso scale (in between single rovings or strands), and on macro scale (on scale of parts to be manufactured). While macro and meso scale can be measured in experiments or derived from filling times in real processes, micro scale is usually not easily assessable and accessible for standard textile materials. Analytical approaches are limited to regular fiber arrangements (square and hexagonal) that are strongly differing from real arrangements. The present work deals with application of a numerical solver to random fiber arrangements to determine micro permeability transverse to the fiber orientation, for later use in meso- and macro-scaled models. As a premise for reliable calculation, guidelines for boundary conditions as well as size and resolution of the representative volume element are elaborated in the course of this work. Calculated out-of-plane micro permeabilities are subsequently compared to real experiments and show good accordance. The influence of binder particles on micro permeability has not yet been conclusively clarified.

Over the last few years the Australian family has again become a focal point for inquiry and intervention. Scholars and researchers, as well as the government, have suggested there has been a breakdown in Australian family life. This has brought in its wake a concomitant increase in divorce and separation, a surge of single parent families, and a decrease in the marriage rate. A broad range of activities has been initiated to both understand the parameters and substance of the subject, as well as to develop means of supporting and strengthening the family.

We present a method for example-based texturing of triangular 3D meshes. Our algorithm maps a small 2D texture sample onto objects of arbitrary size in a seamless fashion, with no visible repetitions and low overall distortion. It requires minimal user interaction and can be applied to complex, multi-layered input materials that are not required to be tileable. Our framework integrates a patch-based approach with per-pixel compositing. To minimize visual artifacts, we run a three-level optimization that starts with a rigid alignment of texture patches (macro scale), then continues with non-rigid adjustments (meso scale) and finally performs pixel-level texture blending (micro scale). We demonstrate that the relevance of the three levels depends on the texture content and type (stochastic, structured, or anisotropic textures).

The eruption of Mount Sinabung causes damage and loss, especially in education. Education was blocked that caused by the factors of parents and children themselves who are responsible for the development and education of children as a matter of education in the family and also the problem of the continuity of the child's learning. This research was descriptive research that uses the method of field observation, interview, and documentation. The main instrument that uses in the field of collecting the data was a questionnaire. The subject of this research were students and parents at SMA N 1 Simpang Empat. From the research, the presence of children in the family educational issues such as sources of funds (for the continuity of children's learning), and Problems Psychologist Parents (Post-eruption of Mount Sinabung) and also there is that there were some problem that Against Child Survival Learning These include: limited transportation, finance, atmosphere learning and time. As for overcoming this issue either from the government itself as scholarships for school children, as well as from the non-governmental donations from individual or group of people.

An analytical and cartographic method of biomass distribution and plant formations at a multi-scalar level is developed based on bioclimatic variables extracted from the Thornthwaite Water Balance (WB) and the Bioclimatic Balances (BB) of Montero de Burgos & González Rebollar. As a result, a distribution map involving Types of Bioclimatic Regimens (TBR) is obtained leading to the identification of a multi-scale classification at different levels: zonal (macro-scale) with 5 types, regional (meso-scale) with 27 types, and local (micro-scale) with 162 plant formations subtypes, conditioned by lithology-soils, the relief exposure to wind or sunstroke respectively and obtained through the combination of TBR and ombroclimates.

This is the second of a two-paper series describing a multi-scale modeling approach developed to simulate crack sensing in polymer fibrous composites by exploiting interruption of electrically conductive carbon nanotube (CNT) networks. The approach is based on the finite element (FE) method. FE models at three different scales, namely the micro-scale, the meso-scale and the macro-scale, have been developed using the ANSYS PDL environment. In the present paper, the meso- and macro-scale analyses are described. In the meso-scale, a two-dimensional model of the CNT/polymer matrix reinforced by carbon fibers is used to develop a crack sensing methodology from a parametric study which relates the crack position and length with the reduction of current flow. In the meso-model, the effective electrical conductivity of the CNT/polymer computed from the micro-scale is used as input. In the macro-scale, the final implementation of the crack sensing methodology is performed on a CNT/polymer/carbon fiber composite volume using as input the electrical response of the cracked CNT/polymer derived at the micro-scale and the crack sensing methodology. Analyses have been performed for cracks of two different lengths. In both cases, the numerical model predicts with good accuracy both the length and position of the crack. These results highlight the prospect of conductive CNT networks to be used as a localized structural health monitoring technique.

ABSTRACT For preparing the Indonesian students that mastering the 21st century skills, the teachers as the intermediary of the students and the government should be ready to implement each. Meanwhile, from the teachers' readiness, there might be differences between their perception and observed reality. For this reason, the study was to investigate the discrepancy between perceived and observed reality on the implementation of the 21st century skills by the English teachers at primary school. This study is needed to conduct to get real information about the teachers' readiness for implementing 21st century skills. This research had arranged in the Primary School of Tabanan regency during the English teaching and learning. Six English teachers used as the subject related to their perception and reality of the implementation of 21st century skills. A mix-method design used to collect the data with the quantitative way for teachers perceived and descriptively for observed reality. The questionnaire, observation checklist, document, and interview guide were the method for data collection. The result showed that there was a discrepancy between the teachers’ perceived and observed reality about the implementation of 21st century skills at primary school. The discrepancy was the teachers do not ready to implement the 21st century skills, but they perceived the opposed. Keywords: Discrepancy, 21st  Century Skills, Teaching English, Primary School
