Abstract: In order to explore the change of 50 years’ rainfall trend and abrupt change in WeiHe Basin, we using the annual rainfall data of 21 important control stations in WeiHe basin from 1960 to 2012 to analyze the changes in the time rainfall and the change trend of the annual rainfall anomaly, and using Kendall - Mann method to test the trend of rainfall in WeiHe Basin. It shows that rainfall rate keeps decreasing during the last 50 years, and the change rate of upstream is generally greater than the midstream and downstream. For mutation years, it occurs in 1970s in downstream, in1970s and 1980s in midstream and in 1990s and after 2000 in upstream. It shows that the change of rainfall in different regions have different performance. From the tendency analysis, we can predict that the whole WeiHe basin will keep a decreasing trend of annual rainfall in the future.

Abstract: The station located in Aksu region is distributed under the Tarim Basin oasis which is in arid condition, it is the largest cotton producing area in China, also is has the greatest changes in the Tarim Basin. The study of arid farmland ecosystem water oasis, salinity and nutrient rule change process, water-saving irrigation technology demonstration theory and the ideal place for the sustainable development of agriculture and the oasis are very typical representative. In this paper, we make cotton growing soil water - groundwater changes as the study objection, focusing on the analysis of soil moisture in farmland ecosystem and the correlation between groundwater. The basic data of this paper came from experimental field station in Aksu, such as--soil moisture, groundwater depth, they are segmented by cotton fertility cycle in order to analyze soil moisture trends, combined with the local irrigation analysis of soil moisture under different irrigation curves, finally, we will combine these conclusions with evaporation, temperature and other weather station related data, then make a comprehensive analysis of the relationship between soil water, groundwater depth and amount of irrigation, evaporation. We draw the following conclusions: First, the characteristics of soil moisture conditions analysis can divide the soil into four layers: dramatic changes in the surface layer(0~30cm), water supply layer(30~50cm), graded layer(50~100cm) and are stable layer(100~150cm); Secondly, we found that under different irrigation amount, different evaporation affected by different growth stages of cotton water requirements of different factors; Finally, we fit the trend line chart with two lines means a comprehensive analysis of the soil water - groundwater relationship, while the thesis raised the topic in favor of crop irrigation proposal.

Abstract: Assessment of heavy metal contents in groundwater in vicinities of dumpsites within the Calabar metropolis was carried out. The dumpsites included those located at Akai-Effa, Anantigha, Bogobiri, LEMNA road and Marina beach. The choice of dumpsites was guided by magnitude of operation, history and longevity as related to possible metal speciation, leachate fate and disperssivity. Studied heavy metals included; Fe, Mn, Cu, Zn, Pb, Cd, Cr, Ni, Co and As. Results and interpretation revealed generally the highest concentration of selected metals to be in the vicinities of the Akai-Effa dumpsite (an abandoned and reclaimed automobile repair and scrap metal dumpsite with a long history of operation). This was followed by the Bogobiri dumpsite with a relatively shorter period of operation but a history of frequent incineration of refuse. Hydrochemical modelling indicated the aqueous species of metals to be predominantly free mobile ions, oxides and hydroxides. Other multi-element complexes were also identified at varying degrees of dominance and these were largely hydrated arsenates. Metal speciation in groundwater was adjudged to be controlled by dumpsites longevity, refuse type and associated activities. Current levels and speciation trend create a need for temporal and spatial monitoring for possible hazard prognosis and human health concerns.

Abstract: The Bangangte area belongs to the Cameroon Volcanic Line. The volcanic rocks exposure in the area consist of fine microlitic porphiritic Basalts which still poorly surveyed. Petrographically, the studied rocks are made up of minerals like plagioclase, clinopyroxene, olivine phenocrysts and a lot of opaque minerals within a very fine grained matrice. The Bangangte basalts are quartz normative free and are olivine, Diopside, Hypersthene normative. Alkaline (Na2O + K2O) contents vary from 2.247% to 5.46%. These rocks are low-Mg basalts with the Mg# values vary from 42.86 to 45.95 which are characteristic of primitive mantle source. The studied rocks are alkali to transitional basalts with Nb/Y ratio>1.5. Chondrite normalized spider diagram pattern of REE shows uniform patterns with enrichment in LREE and a relative depletion in HREE. While MORB normalized spider diagram pattern of multi elements reveals a negative anomaly with K2O, with enrichement in LILE and depletion in HREE. The Eu anomalies are positive to nulle and are typical of alkali basalts. The Bangangté transitional alkali basalts were formed in intraplate setting of continental part of the CVL. They are the products of partial melting of about 13% of an asthenosphere made up of garnet peridotite. Geochemically, the studied basalts are similar to alkali basalts from Mount Bamenda.

Abstract: Measurement of soil components such as microbial population, minerals and obviously the content of organic carbon play the important roles for the productivity of crops and plants. The present study was attempted to evaluate the impact of Mr. Trivedi’s biofield energy treatment on soil for its physical (electrical conductivity), chemical (minerals) and microbial flora (bacteria and fungi). A plot of lands was assigned for this study with some already grown plants. This plot was divided into two parts. One part was considered as control, while another part was subjected to Mr. Trivedi’s biofield energy treatment without physically touching and referred as treated. In the treated soil the total bacterial and fungal counts were increased by 546 and 617%, respectively as compared to the untreated soil. Additionally, the conductivity of soil of the treated plot was increased by 79% as compared to the soil of control plot. Apart from microbes, the content of various minerals were also changed in the biofield energy treated soil. The calcium carbonate content showed 2909 ppm in the control, while in the treated soil it was increased to 3943 ppm i.e. 36% increased. Various other minerals such as nitrogen and potassium were increased by 12% and 7%, respectively as compared to the control. Besides, the level of some minerals such as potassium, iron, and chloride were decreased by 9%, 23%, and 41%, respectively as compared to the control. Apart from chemical constituents of soil, the content of organic carbon was also reduced by 8% in the treated soil as compared to the control soil. The overall results envisaged that the biofield energy treatment on the soil showed a significant improvement in the physical, chemical, and microbial functions of soil component. Thus, improved the conductance, supportive microbes, minerals and overall productivity of crops. In conclusion, the biofield energy treatment could be used as an alternative way to increase the yield of quality crops by increasing soil fertility.

Abstract: In this paper, we establish a mixed spin Ising diamond chain model on the basis of the effective-field theory with correlations. The formula of the magnetization and the magnetic susceptibility has been given. Effects of the various parameters such as exchange couplings and the anisotropy on the magnetization and the magnetic susceptibility of Ising diamond chain have been studied using numerical calculation. The results show that magnetization curves appear magnetization plateaus. The numbers of magnetization plateaus change with the exchange couplings and the anisotropy. The magnetic susceptibility changes with the exchange couplings, the anisotropy and the external magnetic field.
