As the Earth continued to cool down, the chemistry of granitic rocks reflect the changing conditions &/or processes of continental crust formation. Compared to the 1.0 Ga charnockites, the 1.0 Ga charnockites in the Eastern Ghats Belt, are more potassium and Rubidium rich, with more negative Eu anomalies and show much less HREE fractionation. Thus the 1.0 Ga charnockites are more evolved in composition and this is consistent with secular evolution of the continental crust throughout the Proterozoic era.
随着地球继续降温，花岗岩的化学性质反映了大陆地壳形成的变化条件和/或过程。与1.0 Ga charnochites相比，东高止带1.0 Ga charnochites富钾、富铷，负Eu异常多，HREE分馏少。因此，1.0 Ga charnochites在成分上更为演化，这与整个元古代大陆地壳的长期演化是一致的。

Soft computing techniques are more and more widely used to solve a variety of practical problems. This paper applied the integration of different soft computing techniques in intrusion detection system(IDS). Due to the increasing incidents of network attacks, building effective intrusion detection system is necessary, but it faces great challenges. Two sorts of soft computing techniques are studied:Artificial Neural Network (ANN) and Support Vector Machines(SVM). Experimental results show that integration of ANN and SVM is superior to individual approaches for intrusion detection in terms of classification accuracy.

Cassava is primarily produced for food in its various forms and Nigeria has been recognized as the largest producer of the crop in the world. Despite the impacts of various weather parameters on crop production, Cassava can still withstand harsh conditions making it a key crop for protecting small holder farming against climate change. This paper therefore examined the relationship between increase in height of Cassava growth rate and agro climatic parameters. The agro climatic indices appraised were Rainfall, Relative humidity, Temperature and wind speed. Interrelationship between these agro climatic variables and increase in the height of growth rate of Cassava was computed using regression analysis. It was discovered that the four agro climatic variables had relationship with one another at either 95% significant level or 99% level. It was also revealed that there is 75% at 95% significant level in the rate of increase in height and yield of Cassava which was accounted for by relative humidity. It was therefore concluded that increase in the height rate and yield of Cassava due to relative humidity was as a result of combined effects of the three other climatic parameters.

A ruthenium complex of the 4-hydroxy- 1,10-phenanthroline ligand was synthesized, and the variation of its absorption and emission intensity and litetime with pH characterized. Excited state lifetime, luminescence intensity, and emission properties were determined. The complex exhibits a maximum at 460nm, and a small red shift at higher pH. The spectra show a well defined isobestic point. Luminescence intensity exhibited a sigmoidal relationship with pH, a behaviour that is similar to those of other ruthenium complexes carrying protonable functional groups. This characteristic is suggestive of the suitability of this complex for pH sensor design for medical practices as well as industrial processes. pH dependence is more evident in the emission than the absorption spectra, a behaviour characteristic of higher pH dependence on the excited than the ground state of the complex. Emission lifetimes of 165.4ns and 3.08ns for the protonated and deprotonated states respectively, were determined and the pK * a value calculated as 3.68.

The subject of the work is 5 goose eggshells. These goose eggshells are chosen with egg-shaped index about 0.69. Counter size of each goose eggshell is measured, including counter shape, major axis and minor axis. Both axial compression testing and external radial pressure testing of each goose eggshell are conducted. Then thickness and density of each goose eggshell are measured carefully with the use of corresponding measuring apparatus. Finally, buckling and strength of each goose eggshell are numerically analyzed with using finite element methods. Results show that strength rather than buckling is the main factor resulting in instability of goose eggshells. The research on goose eggshell could provide efficient bionic information for pressure hulls application in deep-sea manned submersible.

Introduction: Studies from our laboratory have shown that global warming and the low level EMF pollution results in increased endosymbiotic archaeal growth. The archaea can produce methanogenesis from hydrogen and carbon dioxide as well as from acetate. The human body methanogenesis can result in more global warming. Global warming is initially triggered by carbon dioxide and EMF pollution produced by homo sapien industrialization. It is carried forward by human endosymbiotic archaeal overgrowth and methanogenesis. The archaea can induce stem cell conversion and neanderthalisation of the human species. The archaea catabolises cholesterol generating digoxin which can modulate RNA editing and magnesium deficiency resulting in reverse transcriptase inhibition. The archaeal cholesterol catabolism can deplete the membrane rafts of the CD4 cell of cholesterol impeding the entry of the retrovirus into the cell. The archaea can produce permanent immune activation producing resistance to viral and bacterial infection. The archaeal cholesterol catabolism depletes tissue cholesterol producing vitamin D deficiency and immune activation. Thus archaeal overgrowth results in retroviral resistance and generation of the Neanderthal phenotype. The endosymbiotic archaea can secrete virus like RNA and DNA particles. The endosymbiotic archaea can induce uncoupling proteins inhibiting mitochondrial oxidative phosphorylation and generating ROS. The endosymbiotic archaeal magnetite can generate low level of EMF. The low level of EMF and ROS are genotoxic and produce breakages in hotspots of chromosome. It can also trigger rearrangements in hotspots of chromosome inhabited by retroviral and non-retroviral elements producing their expression. The archaeal secreted DNA and RNA viroids can recombine with the expressed retroviral, non-retroviral elements and other genomic segments of the human chromosome generating new RNA and DNA viruses. Thus the neanderthalised humans can serve as an origin for new RNA and DNA viruses as well as mutated retroviruses. The endosymbiotic archaea converts the Neanderthal cells to stem cells. The stem cells are resistant to immune attack. The stem cells can serve as a reservoir for this new RNA and DNA viruses. The stem cells and archaeal cells can also serve as a reservoir for viruses and bacteria belonging to other plants and animals. This helps to generate the species barrier jump in noted in recent emerging viral and bacterial infections. This paper studied the archaeal status in patients with recurrent viral infections and retroviral infections. The generation of RNA and DNA viroids from archaea was also studied. Materials and Methods: Blood samples were drawn from normal population, Neanderthal phenotype, retroviral infection and recurrent viral infection.

Protection of the environment is becoming more important role as pollution and magnetic loads from electronic devices are growing as never before. The radioactive background radiation does not explore explicit increase nevertheless more and more attention is paid to this. An increasing number of countries are paying more attention to measurements of the levels of background radiation from various radioactive sources and to the values of their exposure limits. It is known that the vast majority of background radiation in the enviroment comes from radioactive construction (buildings, roads, etc.) built by humans. It is important to understand its sources, evolution, determining parameters, etc. Radioactivity of the human-built environment is assessed on the basis of building materials, construction techniques, and dose-loading related to building technologies. The Department of General and Environmental Physics in the Juhasz Gyula Teacher Training College at the University of Szeged (Hungary) out radioactive measurements related to background radiation, especially the absorbed dose load from full gamma radiation. Among a wide range of measurements, the most important are: The power of radiation from walls and other parts of buildings. The field, such as radioactivity mapping of the environment. Using maps, we not only have actual data for the radioactivity, but we can follow the impact of the human-built environment (buildings, streets, etc.) on whole background radiation (Koteles, 1994).
