The flora of Cameroon is rich and diverse as evidenced by numerous inventories already carried out. Furthermore, the architecture of the species of this flora is known. However, ornamental species have remained the same and sometimes are exogenous to Cameroon. The overall objective of this study, whose purpose is to “contribute to the determination of some herbaceous forest plants with ornamental virtues”, was to enrich the ornamental flora of Cameroon. The study was conducted in 2016 in the locality of SOA-Yaoundé. To achieve this, field visits were conducted during which pictures were taken. During the field trips, plant material was observed and harvested after a selection. The selection was based on the ornamental features of the plant including the growth habit, shape, arrangement and colour of leaves; shape and colour of the flowers as well as the shape and colour of the fruits. The horticultural aptitudes of the selected species were tested in the nursery to find out their temperament and resistance to pest attack. The results reveal six potentially ornamental forest species, namely Culcasia dinklagei; Recktophyllum mirabile (Araceae), Commelina sp., Pollea condensata (Commelinaceae), Bolbitis sp. (Lomariopsidaceae) and Leptaspis cochleata (Poaceae). The development and use of these ornamental forest species would certainly contribute to the reduction of the importation of ornamental plants into our country and to the development of our horticultural sector through further studies on this theme in larger ecosystems in the forest areas of Cameroon.

During survey of hornbills at various places it was found that Indian Grey Hornbill, Ocyceros birostris is found predominantly in Chandigarh. Indian Grey Hornbill is arboreal and commonly sighted in pairs. They have grey feathers all over the body with a dull white brownish belly. Hornbills are farmers of the forest as they disperse the seeds of many tropical trees and keep the forests alive. Besides this, three pairs oriental-Pied Hornbill were found during studies in the months of November and December. These pied Hornbills are bigger in size, sit and feed on lower branches of trees (Plate 1, 2, 3). Indian Grey Hornbill feeds on leaves and fruits of many trees. The bird takes the fruit or leaves in the beak then jerks its head so that it can gulp it inside. During survey it was also observed that the numbers of Indian Grey Hornbill are more in some areas than others. More roosting sites were found in Northern sectors. It was also observed that in certain areas it is present throughout the year. Maximum number was found in February however, from March to June there were more males as the females were incarcerated. The Indian grey hornbill could be seen preening its feathers (Plate 7). The bird uses itsbeak, moves its neck backwards towards the hind end and keeps on touching the bases of the feathers again and again during mating season, male and female preen feathers of each other (Plate 8). Even the younger birds after leaving their nest, preen their feathers and can be seen having puffed body. The aim of this study is to highlight the preening and feeding behavior of the Hornbill.

Assessment of Ground Water Quality Using Water Quality Index and Hydro Chemical Facies around Industrial Areas of Visakhapatnam, Andhra Pradesh, India

The study was assessed out to know the hydro-geochemistry and groundwater quality in the Visakhapatnam City of Andhra Pradesh. The major objective of this study was to assess the groundwater quality for domestic and another purpose in industrial zone Visakhapatnam, Andhra Pradesh. A total number of twenty (20) samples were collected in 2014 covering the pre and post-monsoon seasons. The groundwater quality was examined by water quality index technique by using major physicochemical characteristics and important trace metals such as pH, Electrical conductivity, Chloride, total alkalinity, Total dissolved solids, Calcium, Magnesium, Sodium, Potassium, Sulfate, Nitrate, phosphate, Iron, copper, chromium, Nickel, Lead. The Results were estimated and compared with drinking water standard as prescribed by Bureau of Indian Standards (BIS, 2012) guidelines for drinking water. The results showed that the Concentration of heavy metals Iron (80%), chromium (10%) copper and nickel in some areas shows exceed the permissible limit. Nine suitable parameters were taken for calculating the water quality index (WQI). The WQI during the pre-monsoon season varied from 28 to 88 and in post monsoon 25 to 78. 60% and 48%of water samples show poor water quality in pre and post-monsoonrespectively due to municipal wastewater, inadequate sanitary facilities. Polluted by industrial effluents, lack of proper environmental norms. It revealed that water is not suitable for human consumption. The rock–water interface was the main geochemical method controlling the chemistry of groundwater. The study results revealed that the quality of the groundwater in Visakhapatnam City area was of abundant concern and not right for human consumption without sufficient treatment. Therefore, monitoring should be given the highest priority Indigenous technologies should be adopted to make water fit for domestic use and the purpose of drinking after treatment.

Tidal dancing of hydrological parameters in the lower Gangetic delta region

A study was undertaken during May 2017 to monitor the impact of tidal actions on the hydrological parameters of the Hooghly estuary. The water quality reflects the impact of Bay of Bengal (sea) water almost on all the variables as revealed from the significant difference of parameter values in high and low tides (except surface water temperature and K). The 12 selected stations from the upstream to downstream regions exhibited uniformity with respect to surface water temperature. Significant spatial variations (at 5% level of significance) were observed with respect to parameters like surface water salinity, pH, alkalinity, DO, BOD, COD, NO3, PO4, SiO3, extinction coefficient, SO4, Na, K, Cl and total N. Along with tidal influences, the anthropogenic factors contributed by the adjacent cities and towns exert a regulatory influence on parameters like BOD, COD, NO3, PO4, extinction coefficient, SO4 and total N.

Hyperspectral Estimation of Soil Salt Content Using Partial Least Square Regression Method: A Review

Tejas U. Padghan, Ratnadeep R. Deshmukh, Jaypalsing N. Kayte., Pooja V. Janse.;JECET; March 2018- May 2018; Sec. A; Vol.7. No.2, 156-161.;[DOI: 10.24214/jecet.A.7.2.15661.]


Soil salinization becomes universal problems mostly in arid and semiarid irrigated agriculture areas. Soil salinity is a process which affects the quality of soil and reduces crop yields and agriculture production. The soil salt content adversely affects the soil physical property including soil water content. The Visible and Near-Infrared Reflectance Spectroscopy provides improved estimation of soil salinity as fast approach to the characterization of soil salt content with spectral resolution of 350-2500 nm. The Partial Least Square Regression Method (PLSR) is frequently used to determine Soil Salt Content (SSC) obtains from the spectral data. This reviews on the estimation of salt content (SC) using Vis-NIR spectroscopy.
