Abstract: Mango is a fruit belongs to the genus Mangifera indica, consisting of numerous species of tropical fruiting trees in the flowering plant family Anacardiaceace. Mango (Mangifera indica) is one of the most important tropical fruits in the world and currently ranked 5th in total world production among the major fruit crops (FAO, 2004). Mango fruit is food. It is very rich in vitamin A and C. It also provides a certain amount of other vitamins and minerals such as riboflavin, niacin, Ca, P and Fe (Jiménez, 2004). Mango pickles preserved in oil and a juice of hot spices to overcome the postharvest loses. Ginger is very important spice/preservative used in mango fruit preservation. The pungent taste of ginger is due to the antimicrobial agent named as gingerols in application for the seek of preservation (Curley and Mark, 1990). Mango fruits sometimes may contain some anti nutrients which......

Key word: Mango fruits, hot spices, anti-nutritional contents of mango fruits, Mango fruit preservation, Shelf-life of fruits.

Abstract: The aim of this research is to develop a water quality index (WQI) of drinking water (wells and bore-holes) in the study areas i.e Mubi-north, Girei and Mayo-Belwa local government areas of Adamawa state, Nigeria based on physicochemical parameters. samples were collected in August-October for the rainy season and January-March for dry season. Some of the Physical parameters were measured at the point of collection. These included temperature, specific conductivity, pH, total dissolved solid (TDS) and dissolved oxygen (DO) using a portable dissolved oxygen analyzer for DO. Hanna portable pH/EC/TDS/temperature meter was used for pH conductivity, total dissolved solids and temperature at sample collection point . All data were collected, mean calculated and recorded....

Abstract: Fenton-like processes are applicable to treatments of all organic pollutants, including chlorinated hydrocarbon, BTEX (benzene, toluene, ethylbenzene and xylene), PAHs (polycyclic aromatic hydrocarbons),
phenols, esters, and pesticides. Moreover, Fenton-like processes are moreeffective with low costs and toxicity. This research used chemical reduction methods to prepareand synthesize nano zero-valent iron (nano-ZVI),
while conducting a batch test to examine the pentachlorophenol (PCP) degradation efficiency ofcontaminated soil by adopting Fenton-like processes (which add hydrogen peroxide to nano-ZVI) to treat three
PCP-contaminated soil samples. First, the analyses of the three...

Abstract: the aim of this study was to examinethe effects of house hold toxins such as Allout insect killer and Maxo insect repellent in different environmental condition on the colonization of carrion by invertebrates.
Allout and Maxo were used because of its common house hold use as an insecticide and its ubiquitous use in society. The investigations aimed to examine the possible effects of these toxins in field-based testing for the
estimation of Post-mortem interval. The field-based testing was done using bovine liver with a solution of Allout and Maxo injected into the tissues. The samples were protected from feeding and removal by vertebrate
scavengers. It was found that the presence of Allout and Maxo significantly affected the time taken for Diptera to colonise the biological tissue. The development/completion of life cycle stages of flesh flies in the sample
treated with Allout was found...

Abstract: Out of the four critically endangered speciesof Anisoptera genera, Boilam (Anisopterascaphula Roxb.) is at the highest risk of extinction in the IUCN Red List. It is critically endangered worldwide due to poor
natural regeneration and short viability of seeds. A nursery trial was conducted at National Forest Seed Centre, Seed Orchard Division, Bangladesh Forest Research Institute, Chattogram to examine the scope of seed
longevity in different storage conditions and durations and to evaluate the effect of storage condition and duration on germination of Boilam seed. Seeds were stored at six different storage conditions viz. open air
(control), sand, chalk powder, normal refrigerator (0~40C), saw dust and ash for different storage durations viz. 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36,39 and 42 days. Storage....

Abstract: Background: With the massive development of the construction sector, the demand for timber, as a construction material is projected to increase over the next half century. It has predicted that with the increment of the global population, industrial roundwood consumption, including timber, will be increased by 28% to 61% from 2010 to 2060.The word timber specifies any stage between its harvesting and fitness for utilize as a construction material. Using of immense quantity of artificial timber preservatives, direct and indirect energy usages for timber processing make a contrast with the sustainability of timber as a construction material.The objectives of this research were (a) to analyze the chemical elements and their composition inserted towards Terminalia arjuna through river water bodies in Sri Lanka and (b) to calculate the compression strength and identify the color changes, grain pattern and texture of sunken Terminalia arjuna.....
