Plant dispersal by Indian flying fox Pteropus giganteus in Madurai region, India
Pteropus giganteus is a largest fruit bat in India, belongs to the order suborder Megachiroptera and it is widely distributed in Indian subcontinent. Four different day roost sites of P. giganteus were surveyed in Madurai district. One single tree roost camp and three multiple trees roost camps were observed in the surveyed roost sites. Among the four roost sites, totally 21 species of plant saplings were identified under the day roost camps. Seed dispersal by this fruit bat shows that they disperse variety of seeds of different plants species in the vicinity of the roosting trees apart from the foraging trees. Borassus flabellifer, Anacardium occidentale, Nerium indicum, Phoenix dactylifera, Prosopis juliflora and Madhuca indica were dominated in the surveyed roost sites and that species saplings were recorded as maximum in the roosting vicinity confirming that P. giganteus indeed helps in seed dispersal to maintain the heterogeneity in the Madurai region.

Polar and ecliptic solar wind during solar maximum.
In this paper we would like to explore observations of solar wind in both the polar and equatorial regions simultaneously at the same time during 23rd solar maximum, in order to compare the similarities and differences in solar wind between two regions. The observed period roughly coincides with polarity reversal phase. The comparative study relates polar and equatorial solar wind using observed data. The polar wind has been extensively investigated by Ulysses, the first spacecraft to perform in-situ measurements in the high-latitude heliosphere and ecliptic solar wind was observed by ACE were used to examine solar wind parameters. The solar wind parameters – temperature, density, speed and solar magnetic field are taken for evaluation. This study elucidates the solar wind variations in equatorial, southern and northern hemisphere in maximum phase. Both slow and fast solar winds are characterized in southern polar hemisphere but fast wind is prevails in northern polar hemisphere. Key words: Solar wind parameters, solar maximum code: EIJAPX 2017

Potential of Consortium of Banana, Orange and Potato Peels as Bio-sorbents in the Purification of Paint Industrial Wastewater
The research aimed at evaluating the potentials of consortium of banana, orange and potato peels as bio-sorbents in the purification of paint industrial wastewater, using column adsorption technique. The experimental conditions observed were pH 4 and 8 and adsorbent doses 1 g and 2 g. Atomic Adsorption Spectrophotometric method was adopted to evaluate the physicochemical properties of the wastewater samples. Results showed that the consortium were effective in the removal of COD, BOD, total solid, colour, turbidity, nitrate, chloride, copper and cadmium while the values of lead, sulphate and phosphate was observed a noticeable increase on the treated wastewater samples. The best experimental conditions according to the adsorption capacity were pH 4 and 1g adsorbent dose. The efficacy of the percentage removal for heavy metal and inorganic anions in the wastewater samples after treatment were in this order: Cl- ? Cd? NO3– ? Cu. It can be deduced that all models can be used reasonably well to describe the behaviour of the adsorption of cadmium, copper, chloride and nitrate. The best model for the column adsorption process was observed to be Yoon – Nelson isotherm model which have the highest correlation coefficient values of the study. The results of this study showed that the agrowastes consortium has the potentials in the treatment of industrial wastewater, which is cost effective, economical and eco-friendly.

Prediction of risk of thoracic outlet syndrome based on x-ray imaging in subjects with transversomegaly in Owerri, Nigeria
Compression of the neurovascular structures crossing the thoracic outlet usually causes severe pain at the neck and this is called thoracic outlet syndrome (TOS). Elongated transverse process (ETP) of the 7th cervical spine (C7) (transversomegaly) is one of the risk factors of TOS. The aim of this study was to measure the length of transverse process (TP) of C7 on plain x-ray of AP cervical spine in order to determine and predict risk of TOS. A cross sectional study carried out on 126 subjects with neck pain referred to the radiology department, Federal Medical Centre, Owerri, Nigeria. Stratified technique was used. Prominent TP rating scale was taken as > 4.12 cm on x-ray cervical spine AP view. Data was subjected to descriptive statistics and relative risk was determined.Mean age of subjects was 54.5 + 2.1 years. Subjects with normal right TP (< 4.12cm) was 105 (83.3%) {males = 48.6% (51) and females = 51.4% (54)}. Prevalence of left transversomegaly (> 4.12 cm) was 7.9% (10). The relative risk patient with transversomegaly is 3.0 times more likely to develop TOS Transversomegaly is 3.0 times more likely to develop TOS compared with a patient whose TP is not enlarged. Male subjects are at more risk than females (p < 0.05). The prevalence of transversomegaly is 12.3 % in the studied population. True AP cervical X-ray projection is implied to patients suspected of having TOS.

Psychological Disclosure Through Jung's Archetypal Images
“Psychological Disclosure Through Jung’s Archetypal Images” explores the archetypal images found in the selected animal poems of Ted Hughes, in order to draw the psyche of the creatures in contrast to the human world. The latent archetypal images of the poems are brought to light by making avail of Jung’s archetypal theory and each image is defined to sketch the psyche of the creatures of the poem with comparison to the human world. “Hawk Roosting,” “Thrushes,” “Pike,” Crow’s Nerve Fails,” “Crow’s Fall”, “Crowcolour,” “Crow’s Theology” and “Crowego” are the poems, and hero, trickster, clown and shadow are the archetypal images applied to analyse the selected poems of Hughes in a psychological perspective.

Radon concentration in water sources in Pwalugu in the Upper East Region of Ghana
Radon is a naturally occurring colourless, odourless, water-soluble gas produced by the radioactive decay of radium. Chronic exposure to radon is recognized as a health risk. Ingested water with elevated levels of radon can present a risk for developing internal organ cancers. Thirty (30) water samples collected from four different water sources (borehole, pond, hand – dug well and river) in Pwalugu and their environments were analysed using the Gamma Spectrometry System. The radon concentration varied from 29 ± 1.1 to 40 ± 2.1 µBq/L. These values fall below the maximum concentration level, of 0.148 Bq/L proposed by the US EPA. The highest concentration was recorded in borehole samples because of the nature of the geology and because no radon was lost due to aeration. The calculated annual effective dose by ingestion varied between 2.920 × 10-7 and 2.117 × 10-7 Sv/y which is below the recommended value of 1mSv/y.

Re-visiting in search of excellence a portfolio management prospective
An investor considering securities investments faces the challenge of deciding which securities to invest in from a vast number of options and allocating his cash among them. The investor is once again faced with the decision of which assets to hold and how much to invest in each security. The two most significant qualities of a portfolio are risk and return. The investor seeks to select the best portfolio by weighing the risk and return characteristics of all available options. Individual stocks and portfolio characteristics alter over time. This necessitates an investor's investment portfolio to be reviewed and revised on a regular basis. An investor always puts his money into a portfolio in the hopes of getting a decent return that is proportional to the risk he is willing to take. The portfolio's return on investment must be quantified, and the portfolio's performance must be assessed.
