Arnavutluk Tavşan Populasyonunda Yerel Farklılaşma

Six measures of body conformation of six rabbit subpopulations were analyzed to determine the quantity of local differentiation of Albanian rabbit population. Data analyses showed that: (i) the local rabbit breed is classified in medium breed group with harmonic body development, (ii) the Albanian local rabbit population is distinguished for considerable level of local differentiation (iii) the main factor of this differentiation is the isolation in distance of rabbit subpopulations (iv) local differentiation can contribute on genetic variability conservation of Albanian local rabbit population that is actually under the pressure of genetic erosion.Arnavutluk tavşan populasyonularındaki yerel faklılaşmaların miktarını belirlemek için altı tavşan alt populasyonunun vücut kon formasyon ölçümleri analiz edilmiştir. Verilerin analizleri aşağıda hususları göstermiştir. (i) Arnavutluk yerel tavşan ırkı harmonik vücut gelişimli orta büyüklükte ırk olarak sınıflandırılmıştır.(ii) Arnavutluk yerel populasyonları önemli ölçüde farklılaşma göstermektedir.(iii) Yerel Populasyonlar farklılaşmasın da en önemli faktör tavşan alt populasyonları arasındaki mesafe izolasyonudur. (iv) Yerel populasyonların farklılığı genetik erozyon baskısı altıdaki Arnavutluk yerel populasyonları korunması sürecindeki genetik çeşitliliğe katkıda bulunmaktadır

Anaerobic digestion process: technological aspects and recent developments

The technology of anaerobic digestion allows the use of biodegradable waste for energy production by breaking down organic matter through a series of biochemical reactions. Such process generates biogas (productivity of 0.45 Nm3/KgSV), which can be used as energy source in industrial activities or as fuel for automotive vehicles. Anaerobic digestion is an economically viable and environmentally friendly process since it makes possible obtaining clean energy at a low cost and without generating greenhouse gases. Searching for clean energy sources has been the target of scientists worldwide, and this technology has excelled on the basis of efficiency in organic matter conversion into biogas (yield in the range of 0.7–2.0 kWh/m3), considered energy carriers for the future. This paper gives an overview of the technology of anaerobic digestion of food waste, describing the metabolism and microorganisms involved in this process, as well as the operational factors that affect it such as temperature, pH, organic loading, moisture, C/N ratio, and co-digestion. The types of reactors that can be used, the methane production, and the most recent developments in this area are also presented and discussed
