Status of small pelagic fish resources and fisheries in Thai waters

The status of the pelagic fisheries and resources in Thai Waters are provided basing on the Fisheries Statistic of Thailand for 1980 - 1995 period. An attempt is also made to assess the current status found among major small pelagic stocks, namely Indo-Pacific mackerel, Indian mackerel, round scad, small tunas, anchovies and sardines. Other technical reports pertaining to pelagic fisheries and resources are also reviewed. In the Gulf of Thailand, most of small pelagic fish have been over-fished, except hardtail scad and king mackerel. In the Andaman Sea, the stock of Indo-Pacific mackerel, which located in the lower part of the coast, and banded trevally show indication of overfishing. To date the recovery of these stocks seems to have improved. For Indian mackerel, round scad, sardines, small tunas, hardtail scad, and bigeye scad, no drastic changes in their catches imply sustenance these resources

Clinical applications of current biomarkers in canine chronic enteropathies

Chronic enteropathies (CEs) are a group of multifactorial gastrointestinal diseases in dogs, which are defined by chronic persistent or recurrent gastrointestinal symptoms, along with histopathological indications of mucosal inflammation. These disorders have gained significant interest in recent years due to their unclear etiopathogenesis, the severity of symptoms and lack of response to conventional treatments. The diagnosis of canine CEs is challenging because of their non-specific clinical symptoms, which require an extensive diagnostic investigations to exclude alternative causes of chronic gastrointestinal signs. Currently, the gold standard for diagnosing CEs relies on histopathologic evaluation and assessing responses to therapeutic trials. However, these methods have limitations in terms of invasiveness, cost and time consumption. Therefore, biological markers that objectively reflect the severity of gastrointestinal disease, assist in diagnosing clinical practice, predicting treatment response, determining prognosis and monitoring disease progression may offer valuable clinical benefits for dogs with CEs. This article provides an overview of the current biomarkers for canine CEs and discusses their potential clinical applications, as well as their advantages and limitations. Furthermore, this review expects to contribute to the identification of future directions for advancing biomarkers in canine CEs research

Field Screening of Sugarcane (Saccharum spp.) Mutant and Commercial Genotypes for Salt Tolerance

Growth and physiological attributes and sugar quality parameters are considered key criteria for screening sugarcane cultivars for salt tolerance. Maximum cane growth and yield were found in a positive check (‘K88-92’) as well as in cv. ‘(A3)AE1-18’ when subjected to salt affected soil. Percent reduction in Fv/Fm, quantum efficiency of PSII (ΦPSII) and water use efficiency (WUE) due to salt stress was considerably low in ‘K88-92’, ‘(A3)AE1-18’ and ‘KK3’ which was associated with very low salt-induced reduction in net photosynthetic rate and growth characters such as shoot length, number of internodes, and internodal length as well as yield traits. In addition, brix, polarlization, fiber, purity and commercial cane sugar (CCS) in ‘(A18)AE2-15’ and ‘(A3)AE1-18’ were well maintained under saline stress. By subjecting the data for various physiological, growth, yield and sugar quality parameters to the Ward’s cluster analysis ‘K88-92’ (positive check), ‘(A3)AE1-18’ and ‘KK3’ were identified as salt tolerant, whereas ‘(A11)AE1-114’ and ‘K97-32’ as salt sensitive

Work motivation, working atmosphere in the office, officer’s relationship with the organization and officer’s attitude toward the future. 2) To compare factors affecting the influence in the performance of their Provincial Electricity Authority classified by gender, age, marital status, educational level, age, location and income. A study of the general status of the respondents and their opinions about the factors influencing the performance of employees in the Provincial Electricity Authority. The statistics used for the data analysis consisted of Percentage. Mean, Standard Deviation, One-Way ANOVA of variance. Based on the results of this study, there are two main topics can be summarized 1) Personal factors include gender, age, status, education level, income, job position, and working hours. Influence in the performance, There was no different Factors affecting job performance of all 12 different organizations. 2) Employees with higher education and employees with different positions, there were a number of factors that influence the performance of all 12 different organizations. So it was in line with the set assumptions at the level significant of .05

Fin-Solar Collector for Producing Heat in Drying Process

AbstractThe study aims to evaluate the efficiency of 3 designed fin-solar collectors applied for gathering heat for the dryingprocess. The experimental set comprises a flat solar collector plate (0.5 sq.m.), which was made of smooth plywood and painted black. Altogether 68 fin sheets were installed on the absorbing plate, generating 0.9 sq.m. sunbeam absorbing area. The fins were made of zinc-coated iron sheets in black cover. The 3 developed patterns included trapezoid, semicircle on top of trapezoid, and isosceles triangle shapes. The glass drying box was installed with a ventilator and a 600-watt heater intended for additional heat. Hot air obtained through the process was tested in dehydrating wet cotton balls. As results, the efficiency of the fin plate and that of the drying process were significantly consistent. The performance of the designed semi-circle on top of trapezoid plate proved to be better than the trapezoid and isosceles patterns

The chamber and the flat-plate solar collector are connected by a duct. The flat plate solar collector is composed of the sheet which absorbs the heat from the copper plate with a thickness of 2 mm.  This plate was painted black with the approximate area of 0.5 square meters. The one-kilogram squids were experimented during 8.00 - 17.00 hrs.  On average, the radiation intensity was over 661 watts per square meters. The squids, at first, indicated 400 percent moisture content. The results reveal that comparing the squids dried by the sunlight with those dried in the specific oven, the moisture content declined to 170 and 70 percent respectively. The rates of moisture reduction were 23.4 and 35.1 percent per hour respectively. When the squids were further dried in the oven with the heat from gas until they showed the moisture as required, the drying time was lessen. Consequently, the gas consumption was reduced by an average of 22.5 percent. The study of the drying efficiency of the squids on hourly basis, it was found that the drying efficiency decreases as the radiation intensity increases. This indicates that the drying rate is invariant.  Also, the research pointed out the drying efficiency of 31.0 percent.
