Abstract The mud crab (Scylla olivacea) is the brackish water resource with the most potential in Bangladesh after shrimp. It is widely distributed in coastal waters, including mangroves, tidal rivers and estuaries, and vast areas of traditional tide-fed shrimp ponds. The mud crab fishery is entirely capture-based and export-oriented with more than 50,000 persons involved in fishing, transportation, trading and export. The species is harvested from wild sources and black tiger shrimp ponds throughout coastal areas of Bangladesh using traditional craft and gear. Due to good price and high demand on the international market and absence of alternate income options for coastal communities, increased fishing intensity has already resulted in severe decline in natural stocks of mud crab over the last decade. Consequently, the catch per unit effort (CPUE) production and export earnings have also declined significantly over the past few years. To increase the natural stock of the resource, it is urgent to introduce both stock enhancement and aquaculture of mud crab in Bangladesh. Post harvest transportation and marketing also need to be improved to reduce high handling and transportation mortality (>30%) of harvested crabs.

The mud crab business is being considered by most marketing operators to be a profitable and sustainable business due to the high demand in the international market. This study aims to determine value addition at different actors-based steps; primary data was collected from 100 respondents (40 collectors, 10 fatteners, 20 depot owners, 20 suppliers and 10 exporters) who were selected randomly from Khulna, Satkhira and Dhaka district. The mud crab analysis reveals that the value addition of the fatteners was the highest among all other intermediaries which was Tk. 11525 and Tk. 10665 per 100 kg of crab for the grade XXLPD in Khulna and Satkhira district respectively, whereas the lowest value addition was Tk. 1450 and Tk. 1090 per 100 kg of crab for grade KS3. The mentioned districts’ highest value addition by depot owners were Tk. 1191 and Tk. 1200 per 100 kg of crab for the grade FF1 respectively, while lowest value addition was Tk. 691 and Tk.750 per 100 kg of crab for the grade L and M, and by suppliers it was Tk. 2918 and 2758 per 100 kg of crab for the grade FF1. The range of value addition by exporters for Hong-Kong and Taiwan market was Tk. 260.25 to Tk. 13825 per 100 kg of crab. Value addition for exporting female crab to Taiwan market was greater than Hong-Kong market.

This article provides a brief overview of novel drugs approved by the U.S. FDA in 2016.  It also focuses on the emerging boom in the development of neurodrugs for central nervous system (CNS) disorders. These new drugs are innovative products that often help advance clinical care worldwide, and in 2016, twenty-two such drugs were approved by the FDA. The list includes the first new drug for disorders such as spinal muscular atrophy, Duchenne muscular dystrophy or hallucinations and delusions of Parkinson’s disease, among several others. Notably, nine of twenty-two (40%) were novel CNS drugs, indicating the industry shifting to neurodrugs. Neurodrugs are the top selling pharmaceuticals worldwide, especially in America and Europe. Therapeutic neurodrugs have proven their significance many times in the past few decades, and the CNS drug portfolio represents some of the most valuable agents in the current pipeline. Many neuroproducts are vital or essential medicines in the current therapeutic armamentarium, including dozens of “blockbuster drugs” (drugs with $1 billion sales potential).  These drugs include antidepressants, antimigraine medications, and anti-epilepsy medications. The rise in neurodrugs’ sales is predominantly due to increased diagnoses of CNS conditions. The boom for neuromedicines is evident from the recent rise in investment, production, and introduction of new CNS drugs.  There are many promising neurodrugs still in the pipeline, which are developed based on the validated “mechanism-based” strategy. Overall, disease-modifying neurodrugs that can prevent or cure serious diseases, such as multiple sclerosis, epilepsy, and Alzheimer’s disease, are in high demand.

Collision Models

Navigational safety is an important issue in maritime transportation. The most frequent type of maritime accident in the port and coastal waters is the ship collision. Although some ship collision models have been developed in the past, few have taken account of wind and sea current effects. However, wind and sea current are critical factors in ship maneuvering. Therefore, based on the previous collision model without wind and sea current effects, this study further develops a ship collision model with wind and sea current effects. Finally, a comparison of the results for the proposed collision model in this study and the ship maneuvering simulator is shown to illustrate the effectiveness of the proposed mathematical model in this paper, followed by the conclusions and suggestions given to navigators, port managers, and governmental maritime departments to improve navigational safety in port and coastal waters.

In the Chinese technological tradition, no sector, apart from that of agriculture, is as rich in original ideas as naval architecture. Over the past three millennia, hundreds of different types of craft have been developed for use on China's shallow lakes, on its fast flowing rivers and along its often stormy coastal waters. Each type was developed for specific use as a means of transportation, and would seem to represent the ultimate answer to the challenges posed by local conditions. Ultimate answer, that is, within the limitations of the traditional building materials with which these boats were constructed and fitted out. Nor was ingenuity confined to construction techniques.

The adoption of digital communications, facilitated by Internet technology, has been among the most significant international business developments of the past 25 years. This article investigates the effect of these new technologies and the changing global business environment to understand how relational approaches to international market entry (IME) are changing in light of macro developments. Despite substantial resources in business practice dedicated to combining relational strategies in digital settings, this analysis of extant literature reveals that fewer than 3% of peer-reviewed research articles in the international marketing domain examine digital contexts. To address this gap, the authors assess 25 years of literature to provide (1) a description of the evolution of IME research; (2) a review and synthesis of pertinent literature that adopts relational, digital, and hybrid approaches to IME; (3) a taxonomy of IME strategies; and (4) directions for further research.

In Canada the hockey arena has served as a place where individuals would not only gather to play hockey but a place for socializing on and off the ice. With today’s high pace, high demand life styles and with the shift in individual’s needs and desires, the arena has lost all of its interactive and engaging traits with the user and observer. The arena offers nothing besides hockey. This thesis will examine the reconsideration of hockey arena design for a sustainable future. Through literatures on past and present arenas designs, sustainability in sports designs and designing sports facilities for communities as a designer we are able to generate new and innovative design responses. Commencing with case studies on sustainable sports design projects, lessons can be learnt to help gather successful design traits, in addition to learning from mistakes of the past. Through a design proposal which implements a new and innovative scheme, and by challenging design through the three issues of sustainability, will aid in demonstrating how by expanding the role of the arena will provide beneficiary needs and desires for a community. This would potentially add to longevity of the infrastructure while increasing its overall building usage. By addressing these problems as a designer we can recreate the arena back into a destination point in which it once was, but now with new flexible, interactive and engaging community and public spaces.

Sabah has extensive mangrove forests surrounded by oceanic waters which provide suitable habitat for many species of animals including mud crabs (Scylla spp.). This study was conducted to obtain information on the species composition, distribution and catch per unit effort in Marudu Bay, Sabah. Samplings were done monthly in five mangrove areas along the river channels in Marudu Bay (06°33’N; 114°44’E) from October 2012 to September 2013 using collapsible baited crab traps. From a total of 1859 mud crab specimens caught in Marudu Bay, three species were identified. Scylla tranquebarica was the dominant species forming 78% of the total followed by S. paramamosain 13% and S. olivacea 8%. The number of males (n=1224) was higher compared to females (n=635) with an average sex ratio male : female of 1.0:0.5. The catch per unit effort (CPUE) showed an average value of 0.55 trap-1 day-1 and revealed a declining trend throughout the sampling. S. tranquebarica was widely distributed in all the rivers surveyed, however, it mostly occurred in near the lower reaches of the river near the areas open to the sea where average water salinity ranged from 12.98 to 14.28 ppt and the environment favoured the growth of Rhizophora sp. Other species, S. paramamosain and S. olivacea, were mostly found in upstream areas covered generally by Nypa sp. and where average water salinity varied from 6.93 to 7.50 ppt. The information on the species composition, distribution and CPUE of the mud crabs in Marudu Bay can be useful for mud crab fisheries resources management in Sabah.

The purpose of this study is to determine the effect of the escape gap of cylinder folding trap on catch per unit effort (CPUE), trap rate, composition, and size of fish caught in the coastal waters of Tuban Regency. The research was conducted in November 2019 by deploying 60 units in ten experimental fishing trips at different locations. The traps were 20 units without escape gap, 20 units with an escape gap of 3 cm x 6 cm, and 20 units with an escape gap of 4 cm x 7 cm. Overall, the experiments resulted in a collection of 22 species of marine organisms, such as swimming crabs (33% of total weight), snails, shrimps, crabs, fishes (55% of total weight), and cuttlefish. The highest CPUE was found for the traps with escape gaps of 4 cm x 7 cm, i.e., 9.18 gr/trap/trip. There was no significant difference in the total catch, the weight of catches, trap rate, and catch per unit effort (CPUE) among the three types of traps.
