Descriptive Approach

This study aimed to reveal indicator plant species in the secondary forest by applying a descriptive approach and field observation as well as refer to releve method. Tral vegetation data of vascular plant at seedlings, saplings, poles, and tree stages that analyzed using MVA.4 (TWINSPAN)  software. The analyzed result indicated 12 groups of associations and 1 group of solitary association in which the species were categorized as dominant. The most often appear species in 12 association group based on their growing shapes were Actinodaphne nitida, Celtis latifolia, Hemappasandra sp., Teijmaniodendron sp., Lea acuelata, Spatiostemon jevensis, Koordersiodendron pinnatum, Sisipus sp., Sterculia macrophylla, Litsea timoriana, Macaranga sp., Aglaia sp., Rhus taitensis, Alstonia scholaris, Archidendron parviflorum, Callophylum inophylum and Ficus sp. While the most dominant species in the solitary association were Chisocheton ceremicus, Cryptocarya sp., Canarium hirsutum, Euodia elleryana, Litsea ladermani, and Litsea timoriana. These species arranged and functioned as the dominant tree structure in the secondary forest along the north Manokwari area of Manokwari.

Accurate predictions of winds, waves and currents within extreme tropical cyclones are critical for shipping, offshore oil and gas, ports and harbours, coastal erosion, tourism and fishing. The paper will describe a unique field observation programme intended to gather in situ data about air-sea interactions in tropical cyclones. The site has been established on the Woodside-operated North Rankin Complex, an offshore gas production facility located off the north-west coast of Western Australia. The facility is multi-purpose. It will assist Woodside to manage platform operations during the cyclone season and to make advances in the estimate of extreme wave crest heights for platform loading while enabling academic researchers to measure air-sea interactions. Concurrent measurements are conducted in the atmospheric boundary layer, on the ocean surface and below the surface all the way to the bottom at 120 m depth. The measurements include fluxes of momentum and energy across the air-sea interface, spray production, directional wave spectra up to high wavenumbers, and will allow us to close the balance of the air-sea exchanges for the first time in extreme field conditions.

Phones and other portable technology can be a distraction for pedestrians, affecting their ability to cross a road safely. This study focused on adolescents and investigated whether using a phone distracts attention while crossing the road. A field observation outside a secondary school in the north of England was carried out over a four-week period in 2018 with permission from the school. Observations included recording what accessories the pedestrian was carrying (phone, headphones or another electronic device) and their associated action (whether they were holding the device, speaking into a phone, looking at it, holding it to their ear or interacting with it manually). We observed whether the pedestrian looked (or failed to look) left and right before crossing the road, whether they crossed when the pedestrian light was on green or red, and whether they crossed within the cross-walk. We found that 31.37% of road crossings were made by adolescents with a phone or other device. They looked left and right before crossing less frequently when they had an electronic device with them, when looking at the screen and when texting or swiping. In conclusion, the safety of adolescent pedestrians is affected by mobile phones and music players.

SummaryRecently, there has been a proliferation of international agreements imposing minimum standards on states in respect of their treatment of foreign investors and allowing investors to initiate dispute settlement proceedings where a state violates these standards. Of greatest significance to Canada is Chapter 11 of the North American Free Trade Agreement, which provides both standards for state behaviour and the right to initiate binding arbitration. Since 1996, four cases have been brought under Chapter 11. This note describes the Chapter 11 process and suggests some of the issues that may arise as it is increasingly resorted to by investors.

Cyclic Variations

AbstractLong-term cyclic variations in the distribution of prominences and intensities of green (530.3 nm) and red (637.4 nm) coronal emission lines over solar cycles 18–23 are presented. Polar prominence branches will reach the poles at different epochs in cycle 23: the north branch at the beginning in 2002 and the south branch a year later (2003), respectively. The local maxima of intensities in the green line show both poleward- and equatorward-migrating branches. The poleward branches will reach the poles around cycle maxima like prominences, while the equatorward branches show a duration of 18 years and will end in cycle minima (2007). The red corona shows mostly equatorward branches. The possibility that these branches begin to develop at high latitudes in the preceding cycles cannot be excluded.

We have recently carried out a study of spermiogenic differentiation in two geographically isolated populations of Aphanius dispar (freshwater teleost), with a view to ascertaining variation at the ultrastructural level. The sampling areas were the Jebel Al Akhdar in the north (Group A) and the Dhofar region (Group B) in the south. Specimens from each group were collected, the testes removed, fixed in Karnovsky solution, post fixed in OsO, en bloc stained with uranyl acetate and then routinely processed to Agar 100 resin, semi and ultrathin sections were prepared for study.

Oreochromis mossambicus is currently receiving much attention as a candidater species for aquaculture programs within Southern Africa. This has stimulated interest in its breeding cycle as well as the morphological characteristics of the gonads. Limited information is available on SEM and TEM observations of the male gonads. It is known that the testis of O. mossambicus is a paired, intra-abdominal structure of the lobular type, although further details of its characteristics are not known. Current investigations have shown that spermatids reach full maturity some two months after the female becomes gravid. Throughout the year, the testes contain spermatids at various stages of development although spermiogenesis appears to be maximal during November when spawning occurs. This paper describes the morphological and ultrastructural characteristics of the testes and spermatids.Specimens of this fish were collected at Syferkuil Dam, 8 km north- west of the University of the North over a twelve month period, sacrificed and the testes excised.
