Effects of salt, chili and turmeric powder on the production of high quality dried fish products from Bombay duck (Harpodon nehereus) under open sun drying was investigated. Five different types of dried products (T1-T5) were produced and studied. Moisture content in T3 decreased more rapidly to below 16% within 28 hrs of drying compared to those treated with other treatments (temperature varied from 24.6°C to 34°C and relative humidity varied between  60% and 48%) . Drying process was very slow in control samples where it took 32 hrs for reaching the moisture level to 18.75%. Both turmeric and chili powders had strong repellency effect against insect infestation. Bombay duck treated with salt and herbal products were less infested by the blowfly whereas samples dried under control treatment were severely infested by blowfly.

Studies were conducted to evaluate the drying performance of rotating and solar tunnel dryer for the production of high quality dried fish products. Three marine fish species : Silver jew fish (Johnius argentatus), Bombay duck (Harpodon nehereus) and Ribbon fish (Trichiurus haumela) were used for drying in a rotating dryer and solar tunnel dryer. Temperature and relative humidity were measured at time interval during the whole drying period. During 20 hours of drying in rotating dryer, temperature and humidity varied from 15-20oC and 45 to 72%, respectively. On the other hand, air temperature outside the tunnel dryer varied from 28 to 32.83oC. Temperature inside the tunnel dryer varied from 31.33oC at 3.00 pm to 47.78oC at 12.00 pm. Humidity outside the tunnel dryer ranged from 58.83 to 74% and inside from 33.83% to 68% showing an inverse relationship between temperature and humidity. Moisture content of the fresh Ribbon fish, Silver Jew fish and Bombay duck was in the range of 78.7% to 85.47% with highest value was found in Bombay duck and lowest value in Ribbon fish. After 31 hours of drying in solar tunnel dryer, moisture content decreased in the range of 14.05 to 16.19%. whereas, after 20 hours of drying in rotating dryer final moisture content reached in the range of 16.36 to 19.1%. The present study indicated that drying performance of rotating dryer with low humidity was faster than that of solar tunnel dryer producing quality dried products.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16869 Progress.

Summary This paper examines the horse carvings to be found on Class I and Class II Pictish sculptured stones and considers their reliability as evidence of the sort of horses and ponies that would have existed in the Early Historic Period. An attempt is made to show that the availability in Britain of good sized, high quality riding horses during that period is not inconsistent with what is known of the development and distribution of different types of horses in pre-hislory. The importance of horses and ponies in Early Historic societies is stressed and inferences drawn about the agricultural economy that could support horses and the skilled specialists required to look after them.

Standards have become widespread regulatory tools that promote global trade, innovation, efficiency, and quality. They contribute significantly to the creation of safe, reliable, and high-quality services and technologies to ensure human health, environmental protection, or information security. Yet intentional deviations from standards by organizations are often reported in many sectors, which can either contribute to or challenge the measures of safety and quality they are designed to safeguard. Why then, despite all potential consequences, do organizations choose to deviate from standards in one way or another? This book uses structuration theory—covering aspects of both structure and agency—to explore the organizational conditions and contradictions under which different types of deviance occur. It also provides empirical explanations for deviance in organizations that go beyond an understanding of individual misbehaviour where mainly a single person is held responsible. Case studies of software developing organizations illustrate insightful generalizations on standards as a mechanism of sensemaking, resource allocation, and sanctioning, and provide ground to rethink corporate responsibility when deviating from standards in the ‘audit society’.

Shed Light

This study tends to shed light on early childhood care and education (ECCE) institutions with special reference to kindergartens in Fukuoka, Japan. The choice of the topic for study was derived by the importance of ECCE in children’s life and huge economic growth of Japan after worst effects of world war-II, which are thought to be linked with the education that children receives in Japan. The study is limited to four kindergartens in Fukuoka City and observations made for the study refers to 2018. Herein, different types of institutions providing ECCE, their infrastructural set-up, activities, along with curriculum are discussed. At the end, issues and challenges of ECCE system in Japan are discussed. It has been observed that the infrastructural facility and nature of activities are of high quality. Each and every care is being taken to inculcate habits, as well as to maintain physical and intellectual growth of children. The children seem to be highly happy and enjoy learning via various activities in these schools. It is clear that the devised policies on education and care of children are implemented in full spirit.

Cyprus plans to drastically increase the share of renewable energy sources from 13.9% in 2020 to 22.9% in 2030. Solar energy can play a key role in the effort to fulfil this goal. The potential for production of solar energy over the island is much higher than most of European territory because of the low latitude of the island and the nearly cloudless summers. In this study, high quality and fine resolution satellite retrievals of aerosols and dust, from the newly developed MIDAS climatology, as well as information for clouds from CMSAF are used in order to quantify the effects of aerosols, dust, and clouds on the levels of surface solar radiation (SSR) and the corresponding financial loss for different types of installations for production of solar energy. An SSR climatology has been also developed based on the above information. Ground-based measurements were also incorporated to study the contribution of different species to the aerosol mixture and the effects of day-to-day variability of aerosols on SSR. Aerosols attenuate 5 – 10% of annual GHI and 15 – 35% of annual DNI, while clouds attenuate ~25 – 30% and 35 – 50% respectively. Dust is responsible for 30 – 50% of the overall attenuation by aerosols.

Petroleum-based plastic has been widely used in many industries. However, it takes hundreds of years to degrade and causes widespread pollution to our environment. These problems led to the invention of bioplastics, which were comprised of natural biopolymers made from starch. The production of bioplastics from food-based starches such as tapioca and corn created competition between food and bioplastic production industries. Hence, this research study focuses on producing bioplastic from microalgae residue, which is a non-food based raw material that uses four different types of plasticizers: glycerol, sorbitol, glutaraldehyde and polyethylene glycol (PEG). Microalgae species for identification were obtained from the fish pond at the University Malaysia of Kelantan, before cultivating the species for 14 days. The microalgae residues were extracted through the centrifugation process. Three species were identified under the light microscope, Chlorella sp., Scenedesmus sp. and Monoraphidium sp. The production of bioplastic involved a manual stirring method using a hotplate magnetic stirrer, followed by drying the bioplastic in an oven at 60 oC. Results obtained showed that sorbitol and glycerol from microalgae are suitable to be used as a plasticizer for the production of bioplastic, however glutaraldehyde and PEG are not suitable. Bioplastics that used PEG and glutaraldehyde became cracked and brittle after the drying process. The characterization of bioplastics includes universal tensile testing machines, Fourier-transform infrared analysis and biodegradability tests being processed//undertaken on glycerol-based and sorbitol based bioplastic. Characterization of bioplastics proved that both glycerol and sorbitol have high potential for applications in daily human life. Bioplastics which used sorbitol as a plasticizer could be used in can be applied the production of plastic goods such as toys and household items due to its good resistance toward stress and minimal flexibility. Meanwhile bioplastics which used glycerol as a plasticizer could be applied to the production of plastic bags and plastic food wrap due to its elastic and flexible nature.
