African ecosystems comprise a wealthy repository of biodiversity with a high proportion of native and endemic plant species, which makes them biologically unique and providers of a wide range of ecosystem services. A large part of African populations, in both rural and urban areas, depends on plants for their survival and welfare, but many ecosystems are being degraded, mostly due to the growing impacts of climate change and other anthropogenic actions and environmental problems. Loss of habitat and biodiversity affects livelihoods, water supply and food security, and reduces the resilience of ecosystems in the African continent. Knowledge of the huge African plant and ecosystem diversity, and on the structure, composition and processes involved in vegetation dynamics, is crucial to promote their sustainable use and to preserve one of the most understudied regions in the world. This Special Issue aimed to gather contributions that update and improve such knowledge.

Open University of Palangka Raya (UPBJJ-UT of Palangka Raya) has acknowledged the education-attainment gap between rural and urban areas, and officials have determined ways to connect with students in the far corners of Central Kalimantan. UPBJJ-UT of Palangka Raya has set up study groups (PokJar) through which non urban students acquire university education. Due to its wide range of locations and heterogeneous student populations, PokJar is established through management partnership that constitutes a governing body that oversees the district-wide operation and the delivery of the continuing education programs. On this optimistic basis, the service provided by PokJar administrators becomes central to optimizing quality education in a learning environment where the administrators and students are physically separated. However, the complexity of PokJar service and administrator performance may link to negative perceptions among students. Recognizing the nature of challenges facing PokJar management is expected to usher in the planning of improvement crucial to organizational development that is effective, efficient, accountable, responsive and transparent. This study taps into the quality service, the competence and performance of PokJar administrators of UPBJJ-UT of Palangka Raya in terms of student-perceived values using PLS-SEM method. The overall results address favorable responses, strongly suggesting a good measure of how PokJar administrators� service, competence and performance meet student expectation.

The following studies are all based on the registers of land, population, and revenue contained in the Ottoman archives in Istanbul. They will be limited to the Arabic-speaking provinces of the Ottoman Empire, and to the first century of Ottoman rule. It is not my purpose to attempt a general study of the history of these areas in this period, nor to correlate the information derived from the archives with that obtained from other sources in a comprehensive historical monograph. My aim is rather to offer a series of studies in detail in a certain class of documents and on a few special topics; that is, to make a number of soundings in depth at selected points, rather than a surface survey of this material. The topics have, as far as possible, been chosen so as to give a wide range of variety, dealing with town and country, inland and coastal areas, mountain and plain. The first two studies deal with Palestine, which of all the countries under consideration has by far the richest documentation in outside.sources, and therefore offered the most promising field for a first experimental study. This study presents in outline the picture of Palestine in the early Ottoman period that emerges from the registers, and is intended as an introduction to the material as a whole. It will be followed by a documentary study of the quarters, population, and taxation of the towns of Palestine, and then by further studies on selected rural and urban areas in Syria and Iraq.1

The pomegranate was found very profitable crop as compared to others traditional food and oilseeds crops. Laying the route map to double the farmer’s income has decided to double farmers’ income by 2022 by improving technology and policy, increasing milk production and high value crops production like; fruits and vegetable. It will require annual growth rate 10.4 per cent (Ramesh Chand, 2017). The area and production of the pomegranate was recorded 124 thousand hectares, 884 thousand tons and productivity 71.3 quintals, respectively during 2007-08. There was seen quantum jump in both area and production from 113 to 216 thousand hectares about twice and 745 to 2613 thousand tons almost 3.5 times, respectively, during 2012-13 to 2016-17. The highest share of major importing countries like; United Arab Emirates 42.82 per cent, Bangladesh 24.49 per cent, Nepal 8.03 per cent, Saudi Arabia 5.87, Kuwait 2.57 per cent, Netherland 2.53 and the other like Sri Lanka, Thailand, Bahrain and Malaysia below 2 per cent during (TE) 2016-17. A basket of the pomegranate has embedded in human history and its utilization was associated with several ancient cultures for its fruit, nutritional and medicinal value of pharmaceutical industries. In the recent past, its wide range of significance in human health, malnutrition and provide better livelihood security in rural and urban areas. Therefore, production of pomegranate not only will boost the income of the farmers but also ensure the social security in India.

Endotoxin is a bioaerosol component that is known to cause respiratory effects in exposed populations. To date, most research focused on occupational exposure, whilst much less is known about the impact of emissions from industrial operations on downwind endotoxin concentrations. A review of the literature was undertaken, identifying studies that reported endotoxin concentrations in both ambient environments and around sources with high endotoxin emissions. Ambient endotoxin concentrations in both rural and urban areas are generally below 10 endotoxin units (EU) m−3; however, around significant sources such as compost facilities, farms, and wastewater treatment plants, endotoxin concentrations regularly exceeded 100 EU m−3. However, this is affected by a range of factors including sampling approach, equipment, and duration. Reported downwind measurements of endotoxin demonstrate that endotoxin concentrations can remain above upwind concentrations. The evaluation of reported data is complicated due to a wide range of different parameters including sampling approaches, temperature, and site activity, demonstrating the need for a standardised methodology and improved guidance. Thorough characterisation of ambient endotoxin levels and modelling of endotoxin from pollution sources is needed to help inform future policy and support a robust health-based risk assessment process.

This paper aims to reflect an effort to identify the problems associated with the educational learning process, as well as its function to express some inherent considerations to the most effective forms of the classroom management. Mentioned in this discussion are ways of management for various categories of students, not only from an intellectual level, but also by their behavior. Also, in the elaboration of this theme I was considering that in addition to other development directions of the country, an important place is occupied by the education of the younger generation in our school environments and especially in adopting the methods of teaching and learning management with a view to enable this generation to be competitive in the European labor market. This, of course, can be achieved by giving this generation the best values of behavior, cultural level, professional level and ethics one of an European family which we belong to, not just geographically. On such foundations, we have tried to develop this study, always improving the reality of the prolonged transition in the field of children’s education. Likewise, we have considered the factors that have left their mark on the structure, cultural level and general education level of children, such as high demographic turnover associated with migration from rural and urban areas, in the capacity of our educational institutions to cope with new situations etc. In the conclusions of this study is shown that there is required a substantial reform even in the pro-university educational system to ensure a significant improvement in the behavior of children, relations between them and the sound quality of their preparation. Used literature for this purpose has not been lacking, due to the fact that such problems are usually treated by different scholars. Likewise, we found it appropriate to use the ideas and issues discussed by the foreign literature that deals directly with classroom management problems. All the following treatise is intended to reflect the way of an effective classroom management.
