The weather and climate have been changing continuously due to a wide range of human factors.
The greenhouse gas emission will affect the rainfall also in turn the agricultural is also got affected.
Ice sheets on Greenland and in Antarctica have lost mass, which is very likely to have contributed to sea level rise, another author Baron talks about the rigorous analysis of the business cycle properties of CO2 emissions within and across countries and proposes four salient facts regarding their cyclicality and volatility.
John Rajan, Professor and Head Mechanical and production department of, Sathyabama university, for his valuable guidance and consistent encouragement.

Introduction Processing of PP and Polyamide（PA66） incompatible polymer pair in which PA66 forms microfibrils is a preferable way to achieve higher mechanical properties of PP.
There have been many researchers focusing on these topics, but these composites possessed not excellent mechanical properties [1-6].
In order to develop PP/PA66 in-situ microfibrillar composite that possess comprehensive excellent mechanical properties, the macroscopic fiber reinforced composites with good mechanical properties were learned from, which exhibited the structure characteristics of strong interfacial adhesion and moderate flexible interface[7], profiled microfibrils[8, 9]; Meanwhile consideration based on feature of PA66 microfibrils generated in situ.
The title PP/ modified PA66 (m-PA66) in-situ microfibrillar composite with excellent mechanical properties was prepared by thermal mechanical blending of PP and m-PA66 prepared by reaction blending of PA66 and RIC through a “post-compatibilization” technique.
The crosslinked copolymer content (G) was mainly affected A, D and F.

Metal Doped Titanium Dioxide: Synthesis and Effect of Metal ions on Physico-chemical and Photocatalytic properties Sajid I.
Modifying a material never means the change in base properties entirely but to improve material’s properties for various applications.
The methods of metal doping in titanium dioxide, nature, size, concentration of dopant, etc. are the major factors influencing the characteristics (particle size, surface area, thermal property, band gap, etc.) and the photocatalytic properties of doped titanium dioxide.
Effect of metal doping in TiO2 on physico-chemical properties The characterization of metal doped titanium dioxide involves mainly the examination of textural, structural and catalytic properties.

The segment number of zigzag slot affects collision times between the anchor and zigzag slot.
The overlap ratio between anchor and zigzag slot affects the location relationship between the anchor and zigzag slot, and then affects the latter collision.
The friction coefficient can be affected by many factors, such as contact material, surface roughness, property of contact and so on.

Hence, it is necessary to understand the creep properties of Zr alloys to predict the life of reactor claddings.
Principal factors contributing to the stresses comprise of external pressures from the coolant, pressure generated by fission products inside and pellet-cladding interaction (PCI) [1].
This texture strongly influences mechanical properties, creep, stress corrosion resistance characteristics and various other phenomena.
Textural Characteristics Texture may be influenced by a host of factors that can be divided into two main groups, material and process variables [2].
Hence, in the composite model, the texture effect is first considered by the CODF-Creep model, and the hoop strain rates are modified by the stress enhancement factors.

Introduction Thermoelectric power generation modules have been used as a lightweight means of power generation, especially when power generation per unit weight is an important factor.
Conceptual Design The design is based off 4 concepts: the high solubility of ammonia gas in water, the temperature dependence of solubility for a gas in a liquid, insolubility of polar chemicals in organic solvents, and the scalar property of vapour pressure.
All of these properties were utilized in the Einstein/Szilard design.
Factors Affecting Cooling Rate The final cooling rate which occurs in the condenser is affected by several factors: enthalpy change of the solution as a result of ammonia absorption, rate of ammonia absorption in water for varying concentrations and rate of ammonia transfer from evaporator to condenser.
The pressure of ammonia in the condenser is affected by the rate of ammonia absorption by water.

Introduction The technique of using cement to improve soft soil properties has been widely applied to the treatment of soft soil foundations [1].
The strength and mechanical properties of cement-soil directly relate to effect of foundation solidification [3].
There are many factors affect the mechanical properties of cement-stabilized soil, such as the cement type, cement grade, cement-mixing ratio, curing time and so on [4-8].
The physical and mechanical properties of coastal soil were presented in Table 1.

The research based on the properties of the occurrence of marine gas hydrate, used the principle of gas hydrate decomposition caused by vibration, by adjusting the excitation intensity, frequency, and amplitude.
Its frequency, amplitude, speed changes have the roles on hydrate reservoir and the overlying sediments, the roles including mechanical vibration, cavitation, shock, vibration acoustics, thermal effects and the formation compaction and many other factors, making pressure - temperature conditions in the hydrate reservoir change.
It based on the characteristics of gas hydrate reservoir, saturation and other factors.
This method integrates technologies such as vacuum and heating, the mechanism is simple, but it has many effecting factors.
It needs to further improve the experimental data in the experimental phase, and quantify the reservoir porous media, pore fluid physical- chemical properties accurately, which affect the decomposition of gas hydrate.

To solve these problems, surface treatments are widely used to improve properties of titanium alloy [3, 4].
Physical, chemical and mechanical properties of material surface are important components of the whole performance, especially on special occasion and therefore surface properties play an important role.
Material properties like mechanical strength, hardness and corrosion resistance depend on the microstructure (i.e.
Generally speaking, material properties mainly depend on a number of factors like grain size, phase composition and residual stress.
HCPEB can change these factors to a great extent.
