Complex mineralogical, geochemical, and geological-structural characteristics of a rare collection stone of violet color, phyolithite, in the southwestern part of the Kola Peninsula. This is a metasomatic rock formed under the conditions of brittle deformations on gabbro-anorthosites of the Paleoproterozoic Kolvitskiy rock mass. As a result of potassium metasomatosis, the plagioclase of the initial rocks was replaced by a fine-grained mica aggregate of muscovite-phengite composition with inclusions of Va-aluminoseladonite (up to 20-30 microns). Ba-aluminoseladonite contains 6.6-10.5 % by weight of BaO. Manganese is the only chromophore that accumulates in the rock during metasomatosis. It is manganese that provides the purple-violet color of pseudomorphs of mica according to anorthite. The phyolithites is depleted by REE and has a positive Eu-anomaly. The phyolithites are confined to the areas of fracturing of the north-eastern strike, located in the zone of dynamic influence of the north-western closure of the Onega-Kandalaksha rift of the Riphean age. Other formations (injection conglomerates and lamproites) are also associated with the formation of this structure, which owe their origin to an intense fluid flow.

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.

Late Roman

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.

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.

Mesopelagic Species

The capture of the cornich blackfish, Schedophilus medusophagus, larvae from the Adriatic Sea represents an easterly extension in range of this species, and the first larval record in Adriatic waters.Schedophilus medusophagus Cocco, 1839, is a mesopelagic species from temperate waters of the north-eastern and north-western Atlantic and the western Mediterranean (Bini, 1968; Tortonese, 1975; Haedrich, 1986). The first record of this fish from the Adriatic Sea was reported in 1880 according to Ninni (1912). The second record was during the invasion of medusae Pelagia noctiluca (Malej, 1982; Rottini-Sandrini & Stravisi, 1982; Vučetić, 1982,1983) in Pelješac channel near the town of Korčula-island Koršula (central Adriatic) in 1982 (Onofri, 1986). Ten juvenile specimens, from 10·0 to 20·0cm total length (TL), were collected with medusae at 2m depth. This record Onofri (1986) connected with the ingression of inter-median waters (50–100 m) in the central Adriatic influenced the increase of salinity and temperature in 1982. Jardas (1996) noted that S. medusophagus is a very rare species in the Adriatic Sea.

Charnwood Forest, since 1891, the date of the last paper by Canon E. Hill and myself, has been investigated by the Geological Survey. Though part of their map and the accompanying memoir have not yet been published, the general results of their work have been announced by Professor W. W. Watts, by whom most of it was executed. As we stated at the time, we were far from being satisfied with some important points in our own conclusions; so that since my return to Cambridge I have studied my specimens and slices from the north-western region, which had presented to us the more serious difficulties. In 1891 I had been led to regard the characteristic rocks of Peldar Tor and High Sharpley as lava-flows, but considered the dominant rocks of Bardon Hill to be mainly pyroclastic. Professor Watts, however, maintained the intrusive character of the first and second, while taking the same view as myself about the third. The lava-flow hypothesis had appeared to me the more probable, because I doubted whether a mass so large as the Peldar-Bardon porphyroid, if intrusive, could have maintained throughout a texture so uniformly fine-grained, and I had found in the Bardon quarries fragments of it embedded in rock which I then supposed to be a somewhat altered tuff, closely related to the High Sharpley lava.

Archaeological Excavations

In the course of archaeological investigations of the villa with peristyle in 2010 and 2011, a room of circular plan in the north-western segment of the villa and to the north of room w-24, was discovered. The room had annexes in the east and west and is analogous to the stibadium A discovered in the north-eastern section of the villa. Further investigations of the room called stibadium B revealed that the stibadium walls were decorated with a facing of marble slabs and the floor was covered with exceptionally well preserved high quality mosaic. Archaeological excavations in 2015 defined completely the system of floor and wall heating. The mosaic floors in stibadium B are conserved. The area to the west of the stibadium has also been explored and a channel with the remains of a lead water pipe was discovered there. The terrain to the north of the northern wall of the villa with peristyle was also levelled.
