Abstract: Climate change has the propensity to alter rainfall and temperature regimes across the world, including Nigeria. This paper investigated the trends of rainfall and temperature in northeastern parts of Nigeria, based on data obtained from Nigeria Meteorological Agency for the period of 66 years (1949-2014). The Statistical techniques used for analysis are Mann-Kendall's test for trend, descriptive statistics, time-series plots and correlation analysis. The analyses performed involve the use of XLSTAT 2016 and Excel 2007. Results show a decreasing trend in annual total rainfall over both a long-term period (1949-2014)..............

Keywords: Trend, Rainfall, Temperature, Climate change, Mann-Kendall test, Nigeria.

Abstract: Plastic is one of the major source of pollutants at present time in the world, regularly used for packaging materials, carry bags, manufacturing of different types of materials etc. So, to reduce the increasing environmental pollution from synthetic plastic an alternative must be developed. This need can be fulfilled by use of bioplastics. Polyhydroxyalkanoates are polymers produced by bacteria among which Polyhydroxybutyrate (PHB) is one major group. Bacterial polyesters have attracted much attention as biodegradable biocompatible polymers. Poly-3-hydroxybutyrate, a microbial produced thermoplastic and gained major importance due to their structural diversity and close analogy to plastics..............

Abstract: Characteristic geomorphological evidences, preserved around the snout of the Bara Shigri Glacier in the district of Lahaul-spiti in the Himachal Himalaya, suggest that this glacier underwent successive stages of fluctuation during its retreat after a considerable surge in the Little Ice Age under climatic deterioration. Three sets of conspicuous retreat moraines with varying sizes and extensions have been identified and interpreted. Fresh lateral and terminal moraines, extending from the snout of the glacier down to the Chandra River bed for a distance of about four kilometres, suggest that the maximum advance during the Little Ice Age took place down to that position and formed a temporary shallow lake..............

Abstract: Research conducted by Akbar et all., (2015) showed that in general the Nypa Palmsap productivity remains low, whereas the required amount of sap relatively enough to produce the amount of brown sugar made many of them to be economical, there is no research about this, so research on productivity was needed. The research object is the population of Nypa Palm trees planted (J1) and a population of Nypa Palm trees that grow naturally (J2). In both populations tree fruit bunches is done wobble technique for tapping sap. The sap generated from both the tree population accommodated...........
