The study was conducted to compare the rate of change of selective climatic variables such as annual maximum and minimum temperature, annual total rainfall and annual average humidity among the three different climatic sub-regions (Western zone, northwestern zone and north-eastern zone) of Bangladesh. Annual averages of climatic parameters were calculated to analyze the trend lines, variation and change rate of climatic parameter during the study period. Five years moving average rainfall and humidity were also determined. It was observed that change rate of annual maximum temperature and annual average maximum temperature both were highest in north-eastern zone at the rate of 0.048 and 0.046°C per year, respectively. Highest annual minimum temperature change rate (0.003°C per year) was also found in the north-eastern zone but highest annual average minimum temperature change rate (0.034°C per year) was found in the north-western zone. Average annual rainfall was decreasing insignificantly in all the three climatic sub-regions whereas the highest change rate (21.50 mm per year) was observed in the north-eastern zone of Bangladesh. Highest annual average humidity change rate (0.113% per year) was found in the north-western zone of Bangladesh and five years moving average of annual average humidity was increasing at the highest rate of 0.132% per year in the north-western zone of Bangladesh.Bangladesh J.

Aims: The aim of the study was to investigate the regeneration status and importance of Hypahene thebaica L. and associated species in Tekeze riparian vegetation of the North western zone of Tigray, Northern Ethiopia.  Study Design: Systematic sampling technique. Place and Duration of Study: The study was carried out along Tekeze riverine vegetation, northern Ethiopia between January 2015 and March 2015. Methodology: Three transects (one and two transects on the right and left side of the Tekeze River, respectively) were laid. The distance between the two transects on the left side of the river was 200 m. Along the transects, 30 plots were established systematically at intervals of 100 m to collect vegetation data. Results:  Eighteen plant species belonging to 12 families were recorded. Fabaceae was found to be the dominant family in the study area and were represented by five species, which contributed to 27.7% of the total species documented, whereas nine families were represented by one species each. The overall density of the study area was 70.97 individuals/ha. Hyphaene thebaica was the second abundant species with 16.13 individuals/ha, and contributed 22.7% to the total density of the riparian vegetation. The total basal area of plants was 1.03 m2 ha-1. Hyphaene thebaica was ranked third and accounts for 12.6% of the total basal area with 0.13 m2 ha-1. The species was the most frequent with 17.02%, followed by Ricinus communis and Balanites aegyptiaca. Balanites aegyptiaca (53.52%), H. thebaica (52.37%) and Ricinus communis (51.76%) were the three most important species. Conclusion: More mature trees were documented than saplings and seedlings, indicating “poor’’ regeneration status for the riparian vegetation. Hyphaene thebaica has shown “fair’’, while most species were found to have “poorly’’ or “no’’ regenerating. Hence a sound management plan is urgently required to sustainably utilize and conserve the riverine vegetation.

In the classification of Romance along a northern–southern continuum the languages which exhibit patterns of active-middle alignment (notably, the HABERE ~ ESSE alternation in the perfect) are also known to have undergone the aoristic drift. This article starts from Smith’s (2016) observation that the north-western oïl varieties have maintained the preterite, while also alternating the two auxiliaries, whereas the north-eastern oïl varieties have lost the HABERE ~ ESSE alternation and undergone the aoristic drift. It is argued that the developments which have occurred in the north-western varieties are not theoretically challenging or unique within the Romània. With respect to the generalization of habere in the north-eastern areas and, less conspicuously, throughout Gallo-Romance, it is claimed that this development was engendered by the rise of a dependent-marking system which follows undifferentiated nominative alignment. It is concluded that the modern Romània exhibits a stronghold of active-middle alignment in a group of central languages, which are essentially head marking.

Two nymphs of the rare Tasmanian grasshopper Schayera baiulus (Erichson), a male and a female, have been discovered in the north-eastern and north-western corners of Tasmania respectively, thus confirming its Tasmanian provenance and suggesting a former wide distribution across the north of the island. The nymphs are described and figured. The female was reared to maturity and the adult genitalia described. The very different environments at the two capture localities are documented. The problems involved in defining the habitat requirements and securing the survival of the species are discussed.

A programme, combining a physical survey, intensive pick-up and geophysics, was carried out over 17 ha around the site of a small late Roman fortification, some 6 km south of ancient Pydna. Although the area is intensively farmed, the pick-up survey proved remarkably successful. Hellenistic occupation was identified and a restricted Roman settlement around the site of the quadriburgium. Surprisingly, a new and large late Roman fortification (c. 3–4 ha), equipped with towers, with a densely occupied interior and ‘extramural’ buildings was also found. The north-eastern curtain was discovered by resistivity surveying, the line of the north-western and south-western sides by intensive survey. Pottery and brick monograms from the new site suggests that it dates to the second half of the sixth or possibly early seventh century. It is argued that the quadriburgium may be the site of ancient Anamon, a station on the coastal road from Thessaloniki to Dion. The newly discovered site, clearly of considerable importance, lay on the north bank of the river Sourvala and probably had direct access to the sea, importing both local pottery and amphorae from the eastern Aegean. Its role may have been to protect the fertile coastline of the Pieria and to provide a secure base for the export of agricultural products to the beleaguered cities and settlements around the Thermaic Gulf.

An evaluation was made of the effectiveness elements of the pig breeding industry in Bulgaria in the period 2001-2016, through cluster analysis. The studied period was divided in 3 subperiods, each one with three similar groups (clusters). Through application of cluster analysis, the proximity of the different administration regions in the country was defined in accordance with certain indicators of the pig breeding effectiveness. It was found that in the first cluster for the period 2001-2006 fall North-Western and South-Western region. The North-Eastern and North-Central region form the second cluster. The South-Eastern and South-Central region fall mainly into the third cluster. In the first cluster for the period 2007-2011, the North-Western, South-Western and South-Central regions have a priority with the lowest number of sold animals. The North-Eastern and the North-Central region, forming a third cluster, remain with the highest effectiveness of the pig farming. After the end of 2013 an aggregation of the sector began. For the period 2012-2016, the second cluster is formed from three regions - North-Western, South-Western, and South-Central in 2013.

Mutual Relations

In phase B1, and very prominently – in phase B2 of the Roman Period, tribal groups of the north-eastern territories of the Przeworsk culture displayed a number of characteristic regional elements. These elements are mostly seen in female outfits that become much richer and more varied than elsewhere within the Przeworsk culture territory. The features specific for the Eastern Przeworsk Zone, like e.g., a very high frequency of dress elements made of copper alloys, would be largely the effect of mutual relations of these people with communities of the Wielbark culture from Eastern Pomerania. Though outwardly only ethnographic, this specificity of the material culture may have deeper underlying causes, since starting with phase B1, there is evidence of two basic types of Eastern Przeworsk cemeteries. In both cases, the women’s grave furnishings display general Eastern Przeworsk characteristics. In cemeteries of the first group weapon graves disappear already in early phase B1. These cemeteries fell out of use before the end of phase B2 and reflect the full, or nearly full withdrawal of the ‘Przeworsk’ community from that area. The second group form Przeworsk cemeteries with ‘standard’ weapon graves. From phase B2/C1 on, the Wielbark culture newcomers continued to use many of these cemeteries. Many of them were then continuously used from phase B2/C1 by the Wielbark culture newcomers. It appears that a part of the Przeworsk population from the Eastern Zone probably joined Gothic (Wielbark) tribes then moving south. Recently many brooches recognized traditionally as definitely ethnographic markers of the Przeworsk culture (types Almgren 43 and Almgren 129) have been registered in the western provinces of nowadays Ukraine. However, these finds are already much more numerous than those from the ‘core’ territory of the Przeworsk culture – for the time being, this phenomenon seems to be inexplicable.

La Functional Urban Area (FUA) di Milano è un’area densamente popolata (2.254.263 abitanti) dove l’approvvigionamento idrico è garantito esclusivamente mediante prelievi idrici sotterranei. Per questa ragione la protezione della qualità delle falde rientra tra le priorità delle politiche ambientali di Regione Lombardia. Recentemente è stato avviato un programma di studi ed interventi aventi lo scopo d’individuare i principali plumes di contaminazione da solventi clorurati distinguendone l’impatto da quello legato all’inquinamento diffuso. In questo articolo si presenta il modello di flusso sviluppato per il settore NE della FUA di Milano, settore utilizzato quale area pilota per sviluppare e testare una nuova metodologia che combina statistica e modellistica al fine di distinguere il contributo delle fonti di contaminazione puntuale rispetto a quelle diffuse.

Indian Scenario

Globally India is the second largest producer of fruits; however the productivity is significantly low as compared to advanced countries. The majority of the temperate fruits and nuts are being cultivated in the north-western Himalayan and small areas are lies in north eastern parts. High altitude and temperate regions are capable to produce good quality fruits. But the foothill where the chilling is insufficient adversely affects the yield and quality. In India, majority of the temperate fruits were introduced from other parts of the world and some are indigenous to India like walnuts and wild apple species. Therefore, the improvement of the temperate fruits and nuts were taken place mainly through introduction of promising cultivars. The exotic cultivars are still the backbone of fruit production in India particularly for apple, pear, peach, plum and cherry. Promising varieties were introduced from USA, UK, Germany, Italy, France, Australia, New Zealand, Hungary and Bulgaria and were evaluated for commercial exploitation. However, in walnutand almonds, production is mainly from Indigenous cultivars/ local land races. These consisted of non-descriptive trees and highly variable in yield and quality traits. Recently, several varieties have been developed in India in apple, peach, plum, apricot, cherry and walnut. The potential of these varieties are immense for commercial exploitation. The paper attempt to document the accomplishment made in temperate fruit and nut improvement in perspective to Indian Scenario. The information is valuable for breeders and academician for further studies.
