Soil-cement bricks are good examples of environmentally friendly products. This brick is the combination of soil with compacted cement with no combustion in its production. In this work the physical chemical characteristics of the soil from Piaui for producing this material were investigated. Samples of the soil were collected in three potteries from the county of Bom Jesus and pH analysis were carried out, as well as the rate of organic matter, texture, particle density, limits of liquidity and plasticity rates. The results have shown that the soils have acid tones (pH 5,49 a 6,11), which can be neutralized by adding cement, and organic matter percentages up to 1%. The samples have shown predominantly clay-rich textures with adequate plasticity limits, however, values of liquidity limits and particle density above recommended. Altogether, these soils tend to present viability concerning soil-cement brick production, provided that corrections with additives are made in order to minimize this effect.

Over the last few years, the amount of space occupied by bees in the French public debate together with the well-known benefits of the products of their hive has attracted the interest of social scientists. Indeed, bees have become a symbol of the biodiversity crisis. Social scientists, like us, are sometimes invited to join multidisciplinary projects run by biologists specializing in bees. The aim of such involvement is to help the biologists to convince professional beekeepers to make their practices greener, notably with respect to their handling of the Varroa mite. However, the beekeepers we studied in the south of France are not keen to give up their conventional practices. Based on chemical products, these are efficient, simple, and cheap as opposed to environmentally friendly, chemical-free techniques (scraping or removal of the brood), which are seen to be riskier and more complicated to implement. This article describes and analyzes these obstacles and the relationship to scientific and nonscientific knowledge they reveal.

<p><em>Tea leaf plucking is an important activity that can determine the quantity and quality of tea production. Tea plantations characteristically have variations of slopes that affect the performance of the picking process. This study aimed to analyze the performance efficiency of tea plucking activities using plucking machines and scissors. Field data were collected from several blocks in the South Gambung and North Gambung afdeling. Data collected consisted of the elevation of the place, the slope of the land, the plucking area, plucking time, the number of pluckers, the plots length of the plucking activity, the width of the plots, and the harvested tea's weight. The data collected were processed into field capacity and tea plucking performance efficiency, which were then analyzed descriptively. Results showed that the slope of the land has an effect on work efficiency of 3.00%-8.68%. The effective and theoretical field capacity of tea plucking machines is 0.14 hectares per hour and 0.20 hectares per hour, respectively, while the scissors is 0.015 hectares per hour and 0.020 hectares per hour. The quality of tea harvested with machines that meet the requirements is 44.10%, better than scissors harvested, which is only 28.09%.</em></p>

Пчелы и широко известные полезные свойства продуктов пчеловодства, которым в общественных дискуссиях во Франции уделялось и уделяется значительное внимание, в течение нескольких предыдущих лет стали предметом интереса французских социальных исследователей. Пчелы фактически превратились в символ кризиса биоразнообразия в стране. Социальные исследовате-ли, включая авторов данной статьи, иногда участвуют в мультидисциплинарных проектах под ру-ководством биологов с целью помочь убедить профессиональных пчеловодов внедрять более эко-логичные практики пчеловодства, особенно в том, что касается борьбы с клещом Варроа – смер-тоносным вредителем пчел. Однако, как выяснилось в ходе нашего исследования на юге Фран-ции, местные пчеловоды не спешат отказываться от привычных методов своей работы. Они про-должают использовать химикаты, которые просты в обращении, дешевы и эффективны, игнори-руя при этом более экологически безопасные, но, по их мнению, более рискованные и сложные в применении техники, такие, как чистка или удаление части пчелиного расплода. В данной статье нами анализируются препятствия на пути внедрения более экологичного пчеловодства во Фран-ции, и исследуется отношение к научному и ненаучному знанию, которое эти препятствия обна-руживают.

The article considers eco-economic aspects of using the fishing capacity of the basin of South Baikal in the framework of the development of tourism of the coastal territory within Slyudyansky Municipal District of Irkutsk Oblast and within the entire southern Baikal Region. The article proposes to more strongly focus on developing sport and recreational fishing in this most developed area of Lake Baikal. The eco-economic and legal analysis carried out by the authors allows them to conclude that the traditional regulation of the stock of omul in Baikal by determining the total allowable catches and quotas is not effective enough, since it has led to the prohibition of not only industrial but also limitation of sport and recreational fishing for omul. At the same time, there is no reliable data that recreational fishing along the southern coast of Baikal is the reason for the decrease in the total stocks of omul in Baikal. On the contrary, the South Baikal fishing area can become the basis for a more dynamic development of the tourism industry in the region, including such types of it as cognitive tourism, ecological tourism and sports and recreational one. Moreover, it is the South Baikal fishing area and the coastal territory of Slyudyansky Municipal District that can become a testing site for developing more optimal (considering the specifics of various areas of Lake Baikal) ecological approaches to the regulation, rational use and reproduction of the stock of omul in Baikal for the purposes of sport and recreational fishing at Lake Baikal, as well as development of an environmentally friendly tourism industry in the region. The authors propose to review the strategy of fishery development of the stocks of omul at Lake Baikal and remove restrictions on recreational fishing, accompanying this with organizational and legal measures that allow obtaining reliable statistical data on catches. Precisely in this most economically developed area of Lake Baikal it is advisable to practice the organizational and legal mechanisms for the environmentally friendly development of tourist and recreational activities based on the available water bioresources of the unique lake.

One of early childhood education that can help children to convey ideas and imagination is art. Eco-print is atechnique of art that utilizes natural materials as its ingredients. It has the potential to be a teaching materialin early childhood education so children can appreciate and learns environmentally friendly art by harness thenatural material around them. However, an eco-print lesson in early childhood education is still scarce due tothe lack of teaching materials and the lack of the teacher’s knowledge, specifically about eco-print techniquesfor early childhood education. This problem initiates the author to design training and teaching materials abouteco-print techniques for teachers of early childhood education. Before the training conduct, there will beresearch preparation, analysis of participant needs, trial and error design of the eco print. After then, evaluationconduct between trainer and participant. Based on an analysis of participant needs, the best eco-printtechnique for this training is hammering, which is the most straightforward eco-print technique. However, thehammering technique, which usually uses a hammer, is replaced with pestle wood because it is safer forchildren. The implementation of training was carried successfully in the South Jakarta through the POSDAYAcommunity. The result shows that teachers can accept the teaching materials due to the nature of its easyimplementation, easily obtained material, and safety procedures.

Soil-cement bricks are sustainable and economically viable alternatives due to the possibility of residue utilization. CNSL (Cashew nut shell liquid ) is an example of residue from the cashew industry that can be reused in many applications. Therefore, the present work had as its objective to produce soil-cement bricks having CNSL as a constituent of the formulation. The samples were obtained from the mixture of pure CNSL, soil and cement (1:10). The soils used in the research were extracted from the south of the state and the mixture was pressed in a modular manual press. The samples were submitted to resistance and permeability tests and the results related to resistance and compression showed that the bricks presented an average of 2,3 MPa and were in accordance with what is suggested by NBR 8491/12. The presence of CNSL also altered the permeability of the material which was obtained. Hence, one may conclude that the presence of CNSL satisfactorily influences upon the properties of soil-cement bricks.

AbstractLong-term cyclic variations in the distribution of prominences and intensities of green (530.3 nm) and red (637.4 nm) coronal emission lines over solar cycles 18–23 are presented. Polar prominence branches will reach the poles at different epochs in cycle 23: the north branch at the beginning in 2002 and the south branch a year later (2003), respectively. The local maxima of intensities in the green line show both poleward- and equatorward-migrating branches. The poleward branches will reach the poles around cycle maxima like prominences, while the equatorward branches show a duration of 18 years and will end in cycle minima (2007). The red corona shows mostly equatorward branches. The possibility that these branches begin to develop at high latitudes in the preceding cycles cannot be excluded.
