This study is to investigate the status of using rope in purse seine fisheries in Viet Nam based on surveyed data from 13 provinces/cities across country. Statistic data were taken randomly from 30 purse seine samples per each region of North, Middle, and South by pre-designed questionnaire with direct survey method of fishing gears combined with interview with the owners/captains. The results indicated that the initial constructing and annual replacing ropes of purse seine is mainly concentrated in the group of diameters from 10 - 20 mm. Up to 98% of Polypropylene (PP) material is used in Vietnamese purse seine. Float line and lead line are used the most ropes in purse seine. In purse seine fisheries, the annual additional rope is one quarter of the original amount of rope fitted. Purse seine in the Middle and the South is larger than that in the North of Viet Nam. The ratio of lengths between the float line and the lead line among the regions is different. The ratio of the main purse line with the lead line ranges from 1.1 to 1.75. Average life expectancy of main purse line is lowest in rope types of the purse seiners. The characteristics of the fishing grounds are different in these three regions, so the rope of purse seine is also different.

Abstract One of the three Critically Endangered and endemic primate species in Viet Nam, Delacour's langur Trachypithecus delacouri, is restricted to the north of the country. The largest remaining population is in Van Long Nature Reserve, Ninh Binh Province, and the second largest is in nearby Kim Bang Protection Forest, Ha Nam Province, with other populations believed to be too small for recovery. The population in Van Long has been well studied but the status of that of Kim Bang has not previously been adequately evaluated. To address this, a survey was conducted during 10 August–7 October 2018. In total, we recorded 13 groups comprising a total of at least 73 individuals, almost doubling the highest number reported in previous studies. We documented six new groups in Lien Son and Ba Sao communes in Kim Bang. Our findings indicate there is a high likelihood that Delacour's langur population in Kim Bang will recover and could be important for the long-term conservation of this Critically Endangered species. However, immediate and appropriate conservation measures need to be implemented to protect the population from major anthropogenic threats, namely poaching and habitat destruction, detected during our survey.

I.Since the end of World War 11, approximately eighty new states havebeen established. Only two, Pakistan and Cyprus, have undergone theagony of dismemberment when Bangladesh broke off in 1973 and theTurkish Republic of Northern Cyprus was declared in 1983. The worldmay now be witnessing the possible breakup of yet a third state:Lebanon, whose disintegration has been accelerated since the June 1982Israeli invasion.Shortly after the invasion began, Henry Kissinger assessed itsconsequence for Lebanon’s future, concluding, “It is neither desirablenor possible to return to the status quo ante in Lebanon.” One possibleoutcome was that some Syrian and Israeli forces would remain in thenorthern and southern ends, respectively, and the central government’sauthority would ostensibly cover the rest of the country. Implicit in theKissinger diagnosis is the possibility of eventual partition.Though the gloomy assessment by the “wizard” of US. foreign policyshould by no means be construed as a portent of an official shift awayfrom the publicly stated US. support of “Lebanon’s sovereignty andterritorial integrity,” a shadow was cast on the country’s prospects.Subsequent developments have seemed to indicate that Lebanon’sdemise looms larger than at any time since the beginning of the civil warin 1975-76.For over a year and a half national fragmentation has proceededinexorably. What many people once could imagine only with difficulty,they now acknowledge: in reality, Lebanon is facing possible death. TheSouth (35 percent of the land area) is occupied by Israel; the North andthe Biqa’ (45 percent) are controlled by Syria; Kasrawan (15 percent) iscontrolled by the Christian Maronite forces (the Lebanese Front forces),which are not subject to the government’s authority. The rest of thecountry-beleaguered Beirut and environs-was until the February1984 breakdown under the government’s shaky control supported bysymbolic US., French, Italian, and British units. The Multi-NationalForce (MNF) was subject to increasing attacks by Muslim leftist factions,as witnessed in the October 23 bombing of the quarters of U.S.Marines and French troops. Thus, instead of keeping peace, the MNFbecame ,a partisan force trying to protect itself. The US. and Frenchforces in particular seemed to have outlived their usefulness as“peacekeepers.” Recurrent fighting in southern Beirut and in theadjacent Chouf mountains, that pitted Christian Maronites and armyunits against Shi‘ite and Druse Muslims constantly threatened theexistence of President Amin Gemayel’s government and consequently arenewal of the civil war. This situation culminated in February 1984 inthe resignation of the Shafiq al-Wazzan’s cabinet, the loss ofgovernment’s control of West Beirut to Muslim-leftist militias, and theimminent collapse of Amin Gemayel’s presidency ...

Neurodegenerative diseases are sociosanitary challenges of today, as a result of increased average life expectancy, with Alzheimer’s disease being one of the most prevalent. This pathology is characterized by brain impairment linked to a neurodegenerative process culminating in cognitive decline and behavioral disorders. Though the etiology of this pathology is still unknown, it is usually associated with the appearance of senile plaques and neurofibrillary tangles. The most used prophylaxis relies on anticholinesterase drugs and NMDA receptor antagonists, whose main action is to relieve symptoms and not to treat or prevent the disease. Currently, the scientific community is gathering efforts to disclose new natural compounds effective against Alzheimer’s disease and other neurodegenerative pathologies. Marine natural products have been shown to be promising candidates, and some have been proven to exert a high neuroprotection effect, constituting a large reservoir of potential drugs and nutraceutical agents. The present article attempts to describe the processes of extraction and isolation of bioactive compounds derived from sponges, algae, marine bacteria, invertebrates, crustaceans, and tunicates as drug candidates against AD, with a focus on the success of pharmacological activity in the process of finding new and effective drug compounds.

While investigating the biology of the North American species of Hypomolyx, field workers in Manitoba found a vestigial, or short-winged, and a long-winged form under apparently identical conditions in about equal numbers. Although biological differences were nor then apparent, there was doubt as to whether they were dealing with one dimorphic species or with two distinct species, A search for morphological characters brought to light numerous differences between the two forms, supporting the view that two species were present. These differences, a description the previously unrecognized species, and notes concerning the status of the genera Hylobius and Hypomolyx are reported below.

The article presents the relevance of the problem, defines the research purpose: to compare the average life expectancy of the population in the areas of the Tula region with different contents of heavy metals in the class of causes of death “Respiratory diseases ”. The authors used the data of the regional mortality register, the results of analyzes of the content of heavy metals (copper, lead, zinc, nickel) in the soil by atomic absorption spectroscopy, and the calculation of the average life expectancy by the algebraic model of constructive logic. The results indicate a decrease in average life expectancy due to the presence of heavy metals in the soil, but the average life expectancy in both contaminated and non-contaminated areas is gradually increasing.
