Propagation Media

Guava (Psidium guajava L.) is a tropical fruit rich in vitamins and beneficial phytochemicals and thus often referred to as a super fruit. Despite the potential nutritional benefits of guava fruit, it has received little research to facilitate its wide-scale production in the Kingdom of Eswatini. This study was conducted with the aim of determining the effects of media and branch orientation on rooting of guava branches propagated by air layering. Media treatments used included vermiculite, compost, top soil, and media mix which was a mixture of top soil, pine sawdust and sand. Branches that were oriented towards the North East to South East and South West to North West directions in relation to the sun were selected for air layering. The experiment was a factorial arrangement laid out in a split plot design where there were 5 replications per treatment. Vermiculite wrapped branches showed the best adventitious root formation in relation to root length, root volume, root mass, rooting percentage and root number in comparison to other media treatments. North East to South East oriented branches produced superior adventitious root development than North West to South West orientated branches. Wrapping branches with vermiculite in combination with the selection of North East to South East oriented branches enhanced adventitious root development in air layered guava branches. It is recommended that farmers who wish to produce guavas of desired quality by air layering may select branches with the greatest exposure to the sun in the North East to South East directions using vermiculite or alternatively compost in the absence of vermiculite as propagation media.

The Cyclopean Terrace Building lies to the north-west of the Lion Gate on the northern end of the Panagia Ridge and faces almost due west across the valley of the Kephissos and modern main road from Corinth to Argos. It lies just below the 200 m. contour line, and one terrace below the houses excavated in 1950–51 by Dr. Papadimitriou and Mr. Petsas to the east at the same end of the ridge. The area contains a complex of buildings, both successive and contemporary, and in view of the discovery of structures both to the south-west and, by the Greek Archaeological Service, to the north-east it is likely that this whole slope was covered by a portion of the outer town of Mycenae. This report will deal only with the structure to which the name Cyclopean Terrace Building was originally given, the so-called ‘North Megaron’, supported by the heavy main terrace wall.The excavation of this structure was begun in 1923. The main terrace wall was cleared and two L.H. IIIC burials discovered in the top of the fill in the south room. In 1950 it was decided to attempt to clear this building entirely in an endeavour to find out its date and purpose. The clearing was not, however, substantially completed until the close of the 1953 excavation season, and this report presents the available evidence for the date as determined by the pottery found beneath the building; the purpose is still a matter for study, though various tentative conclusions can be put forward.

ABSTRACT Multiband observations on the Type Ia supernova remnant SN 1006 indicate peculiar properties in its morphologies of emission in the radio, optical, and X-ray bands. In the hard X-rays, the remnant is bilateral with two opposite bright limbs with prominent protrusions. Moreover, a filament has been detected at the radio, optical, and soft X-ray wavelengths. The reason for these peculiar features in the morphologies of the remnant is investigated using 3D HD simulations. With the assumption that the supernova ejecta are evolved in the ambient medium with a density discontinuity, the radius of the remnant’s boundary is smaller in the tenuous medium, and the shell consists of two hemispheres with different radii. Along particular line of sights, protrusions appear on the periphery of the remnants since the emission from the edge of the hemisphere with a larger radius is located outside that from the shell of the small hemisphere. Furthermore, the north-west filament of SN 1006 arises as a result of the intersection of the line of sight and the shocked material near the edges of the two hemispheres. It can be concluded that the protrusions on the north-east and south-west limbs and the north-west filament in the morphologies of SN 1006 can be reproduced as the remnants interacting with the medium with a density discontinuity.

A further 69 recaptures are reported from a tagging study of pelagic sharks initiated in 1970 in the north-east Atlantic. Galeorhinus galeus tagged in England were recaptured in the eastern Atlantic from southern Spain to north-west of Iceland. Among the 42 G. galeus recaptured the longest time at liberty was about 12 years and the greatest distance travelled was 2461 km. Among the 21 Prionace glauca recaptured the l ongest time at liberty was 10.7 years, and seven sharks moved distances between 4362 and 7176 km. One shark tagged in south-west England was recaptured in the South Atlantic off South America. An Isurus oxyrinchus was at liberty for 4–6 years and a Lamna nasus for up to about 13 years. Lamna nasus were recaptured from northern Norway to northern Spain. The growth rates of the tagged sharks were close to the predicted values for G. galeus, were slower for P. glauca and faster for L. nasus.

Halangy Down (fig. 1) is the lower precipitous slope of the decline from Telegraph Hill (Ordnance Survey B.M. 166. 3 ft.) to the sea at Halangy Porth and Point. Halangy Down and the earlier chambered tomb upon the crest are often referred to locally as ‘Bants Carn’. The true ‘Bants Carn’ is a considerable rock outcrop dominating Halangy Point. This escarpment faces Crow Sound, which separates the north-west part of St. Mary's from the neighbouring island of Tresco. The hill-side is sheltered by the mass of Telegraph Hill from inclement weather from the north-east and east, but is fully exposed to the south-west and west.The existence of an ancient village site here has long been known in the islands. At the close of the last century, the late Alexander Gibson cleared away the underbrush from one of the more prominent huts and made a photographic record of its construction. Shortly after, the late G. Bonsor, of Mairena del Alcor, near Seville, in addition to excavating the chambered tomb, noted a considerable midden together with traces, of prehistoric occupation exposed in the cliffs of Halangy Porth just below the village site. Dr. H. O'Neill Hencken noted Bonsor's description of the midden, and, as nothing was known at the time of the material culture of the ‘village’, he associated the two.

During a visit to the limestone quarries at Caldon Low last September we had the good fortune to discover an interesting exposure of a quartzose conglomerate containing numerous fossils. The bed was exposed in a strong joint-face running approximately N.N.W. to S.S.E., at the northern extension of the quarry on the north-west flank of the Low, just beyond the mineral line of the North Staffordshire Railway. The altitude is about 900 feet O.D. The conglomerate apparently extended some little distance to the south-west before the opening of the quarry, as we ascertained that some 20 or 30 yards had been removed in gaining access to the limestone behind. It appears to extend for some distance round the flank of the Low towards the north-east.

Proactive Measures

With the growing insecurity in the country, many commentators are beginning to question the provision of the 1999 Nigerian constitution, Chapter 2, Section 14 (2)(b), which stipulates that “the security and welfare of the people shall be the primary purpose of government”. In Nigeria today, virtually 50 percent of headline news relates to some form of insecurity affecting almost every part of the country. From the Boko Haram insurgencies in the North East, to Herdsmen – Farmers crisis in the middle belt, to banditry and kidnapping in the North West. From South-South region battling militant agitation, to South-East security menace of separatist agitation, kidnapping and armed robbery. Of recent is the issues of kidnapping and banditry surfacing on highways within the South West region, one would rightly say that the centralized form of Policing structure being operated in Nigeria has completely failed. Hence, agitation for institutionalising the concept of Community Policing in Nigeria. Community Policing is a concept that emphasises proactive measures – preventing the act of crime through intelligence and community participation, rather than reactive policing. It is also principled on partnership and decentralisation of powers for effective crime fighting.

Rainsborough is 1 mile South of Charlton village, in the parish of Newbottle, S. Northants, 20 miles North of Oxford, (SP 526348). The camp lies atc. 480′ OD, and the area enclosed isc. 6·25 acres.It lies on the edge of a plateau: the approaches to it are flat on the north-east, east, south and south-west, but a gentle slope to the north, north-west and west gives it a wide view across the Cherwell valley, towards Madmarston and Tadmarton (see map, fig. 1 and also pl. XXV). The defences are bivallate: the inner bank stands to 10 feet above the interior, and there is a drop of about 15 feet from the crest into the inner ditch; the second bank is very much lowered by ploughing, but still reaches a height of about 4 feet on the south side, where a hedge line has protected it; the outer ditch is nowhere visible on the surface, except on the west, when it carries a higher growth of weeds. The defences are covered with turf: the inner bank has also trees, bushes and the stumps of large beeches felledc. 1950. The bank is riddled with tree roots, and the sandy character of the core has attracted rabbits: recent attempts to dig and smoke out the warrens have slightly damaged the profile of the bank. A small dry stone wall is visible part way up the outer slope of the inner bank in several places.

The Village

From the modern town of Kos, on the site of the ancient capital at the north-east extremity of the island, to the village of Kephalos at the southwest end is a ride of eight hours.The village stands on a chalky plateau which beyond the isthmus marks the beginning of the mountain district of south-west Kos. This in turn is a repetition on a smaller scale of the mountain region, at the other end of the island, which forms the lofty termination to the long central tableland. The highest points of the mountain district are towards the south-east where the fall to the sea is very rapid. The highest neighbouring peak, Mount Ziní, is about an hour distant from the village in a south-easterly direction, while all that lies to the north-west of the main range is high pastoral country with many torrent beds.
