Prospects of Hyperloop Transportation Technology: A Case of China

Hyperloop transportation technology is amongst the most promising sustainable and climate-friendly transportation systems of the modern era. Now China has taken steps to build this transportation system in Tongren city, which located on Guizhou's eastern part [8]. So far, not much work has been conducted on the prospects of this technology, especially for China. In this paper based on extensive literature review, we have analyzed the prospects of this technology in China. Furthermore, this article also discusses the possible hurdles and proposes some suggestions for overcoming the problems in the adoption of this climate-friendly technology

Performance of Tomato (Lysopersicon Esculentum) Germplasms Grown in Bangladesh for Salinity Tolerance Mplasm

A solution culture experiment was conducted to screen out a number of Bangladeshi tomato germplasms for salinity tolerance by exposed to control, 8, 12 dS/m NaCl (salt stress). Salinity tolerance of tomato germplasms were evaluated with respect to salinity tolerance index, shoot and root dry matter production, shoot Na+, K+, Ca2+ accumulation and their respective ratios. A tolerance index was calculated for every single germplasm in root, stem and leaf dry weights and in the K/Na and Ca/Na parameters of these organs. Tomato germplasms responded differently to salt tolerance. Based on the salinity tolerance index caused by the NaCl treatment “BT14 (BARI Tomato 14)” and “BHT5 (BARI Hybrid Tomato 5)” were found to be most tolerant germplasms to salinity with highest salinity tolerance index, root-shoot dry matter production, accumulation of K and Ca and exclusion of Na. Thus, “BT14” and “BHT5” can be regarded as a breeding material for development of new tomato varieties for tolerance to salinity

Activity-Based Protein Profiling in Methicillin-Resistant Staphylococcus aureus Reveals the Broad Reactivity of a Carmofur-Derived Probe

Activity-based protein profiling is a powerful chemoproteomic technique to detect active enzymes and identify targets and off-targets of drugs. Here, we report the use of carmofur- and activity-based probes to identify biologically relevant enzymes in the bacterial pathogen Staphylococcus aureus. Carmofur is an anti-neoplastic prodrug of 5-fluorouracil and also has antimicrobial and anti-biofilm activity. Carmofur probes were originally designed to target human acid ceramidase, a member of the NTN hydrolase family with an active-site cysteine nucleophile. Here, we first profiled the targets of a fluorescent carmofur probe in live S. aureus under biofilm-promoting conditions and in liquid culture, before proceeding to target identification by liquid chromatography/mass spectrometry. Treatment with a carmofur-biotin probe led to enrichment of 20 enzymes from diverse families awaiting further characterization, including the NTN hydrolase-related IMP cyclohydrolase PurH. However, the probe preferentially labeled serine hydrolases, thus displaying a reactivity profile similar to that of carbamates. Our results suggest that the electrophilic N-carbamoyl-5-fluorouracil scaffold could potentially be optimized to achieve selectivity towards diverse enzyme families. The observed promiscuous reactivity profile suggests that the clinical use of carmofur presumably leads to inactivation of a number human and microbial enzymes, which could lead to side effects and/or contribute to therapeutic efficac

Mid storage seed hardening: a mechanical method to maintain seed viability during long term jute seed preservation

Seed plays an important role in agricultural sector for both production and consumption purpose. Availability of vigour seed is one of the major constraints for maximizing crop production. However, healthy seed can also lose its viability during seed storage by changing different physio-chemical properties. Influence of environmental factors and seed containers during storage leading to seed deterioration. In this research, mid storage seed hardening treatment was applied in different aged seeds of jute species (C. Capsularis & C. olitorius) with two types of storage bags. Seed hardening treatment showed the less moisture content with better germination percentage compared to the untreated species of jute seeds. Seed packing in polythene bags during both short and long term seed storages had higher viable seeds compared to the cloth packing seeds. The effect of seed hardening treatment on seed oil content and pattern of oil degradation is distinct in early period of storage. The faster rate of oil degradation, soluble protein and free amino acids was found in seeds of un-treated stored seeds in cloth bag. Contrary, very slow rate of oil degradation was observed in harden seed and stored in polythene bag which indicated better storability of harden seeds

Paclobutrazol and bulb size effect on onion seed production

Field experimentation was done at Bangladesh Agricultural University, Mymensingh during, 2005-2006 to evaluate doses of paclobutrazol (PBZ) and bulb size of onion for their effect on growth and seed production of onion. Onion variety "Taherpuri" with three-bulb sizes viz., small, medium and large was used. Doses of PBZ were 20, 40, 80 ppm and no PBZ was used as control. A two-factor experiment was laid out in a randomized complete block design with three replications. PBZ application significantly reduced plant height, number of tillers per bulb, number of leaves per plant and length of scape. Number of flowers, umbels per bulb, umbel diameter, 1000-seed weight and seed yield were not influenced by PBZ concentrations used. Plant height, number of leaves per plant, length of scape, effective fruits per umbel, percentage of fruit set and seed yield were positively influenced by bulb size of onion. Variable interactive effects of PBZ dose and bulb size for different traits were recorded

An Approach of Automated Electronic Voting Management System for Bangladesh Using Biometric Fingerprint

The existing system of election is running manually and the piloted electronic voting using electronic voting machine (EVM) has many limitations in its mechanism. In this paper we have proposed an automated biometric electronic voting system, where a four layered network system has been used for sending the votes from client to the main database, and there exist three application servers and a client. That means, the proposed systems starts with automated registration system that would provide the secured database of the votersrsquo; information, and voter details will be stored against their finger prints in the main database. Finally, at the end of the day, casted votes will be counted automatically which would take lesser time than the manual system and the result would be accurate, faster and reliable, and thus minimize the corruption
