In order to meet with the requirement of the campus shopping, we put forward the design of campus logistics service platform to serve students’ shopping. In the platform the campus service provider put their sale of foods on the system to meet the students and the students can select and buy their foods by the service platform. Meanwhile, the distribution system formed by the provider and the student of the logistics supply chain and can be complemented by campus logistics distribution. By the platform campus logistics service can meet the commercial requirement of students and businesses.

The effects of combined scouring-bleaching and reactive dyeing were investigated by characterizing the functional groups changed of cotton, betel nut, banana and jute fibers using caustic soda, Hydrogen peroxide and reactive dyestuffs. FTIR ATR spectroscopy provided a fast and semi-quantitative assessment of the removal of pectin, lignin, Hemicelluloses, oil, waxes etc on those fibers surface by comparing the changes in intensity of the carbonyl peak induced by Hydrogen peroxide and caustic soda treatments well as bond changing in reactive dyeing around 4000 cm-1. Above all fibers are not reacting identically during changing impurities and covalent bond forming between cellulose and reactive dyes.

The first geometric–arithmetic index is found to be useful in compute the numerical value of certain graphs and chemical graphs, which is defined as ∑ ( ) √ . We denotes d_uthe degree of vertexuinG.In this paper,we present the general formula for the first geometric-Arithmetic Index for certain graphs and k_r-gluing graphs.

This paper study the NOx pollutants emitted from a single cylinder, 4-stroke spark ignition engine type Prodit; fueled with supplementary Natural gas to LPG. The study focused on the impact of equivalence ratio, spark timing, engine speed, and the added NG volumetric ratio on NOx emissions. The results showed that NOx levels depend mainly on the equivalence ratio, as the higher value of NOx concentrations was on the lean side near the stoichiometric equivalence ratio, and it was reduced when getting far from this ratio. It was observed that retarding spark timing reduces the NOx concentrations by a significant percentage. The NOx levels became higher at medium speeds and reduced in higher and low speeds. NOx levels increased with increasing NG volumetric ratio in the mixture.

The six sigma methodology is most powerful quality improvement technique which is used for achieving, maintaining and maximizing the business success. Six sigma is based on understanding the customer needs and expectation. This study mainly focused on six sigma quality philosophy and other related philosophy that is implemented in these studies to identify the rejection problem which are facing by a manufacturing industry. The six sigma philosophy provides a step-wise quality improvement methodology in which statistical techniques is used for check the changes in the process.

Let a simple graph G is a connected graph. The General Randic Index GR(G) of a graph G is defined as GR(G) = ∑ (�u �v )t ; uv E(G) where �u and �v are the degree of vertices u and v. If t = ,then it is called Randic index which is defined as:- uv E(G) R(G) =∑ √ In this paper, we construct the Randic and General Randic Indcies of Alkanes and unicyclic graphs with application to cycloalkanes.

The thermal performance of proposed model deals with combined double bed vapor adsorption refrigeration system and 9MW of Rankine thermal cycle .The provision of evacuated tube type solar collector (ETC) is available with adsorption system to support the system for continuous cooling effect. The energy-exergy analysis refers live operational data of thermal power plant, and proposed cooling system is adopted as per thermal gain from condenser and solar heater for adsorbent-adsorbate pair of adsorption system. Major units of combined plant (boiler, turbines, condenser, pump, solar collector, adsorption bed etc.) have been investigated in thermodynamic analysis. The main objective of energyexergy modeling is to identify the magnitude of process, cause of losses and rectifying the components. The source temperatures available for both beds of Vapor Adsorption Refrigeration systems (VAdRS) from condenser exhaust and ETC solar system. The adsorbent and adsorbate pair for double bed VAdRS has been recommended by activated carbon as adsorbent and methanol and R134a as adsorbate respectively. This analysis shows the combination of adsorbentadsorbate pair is suitable for low grade heat recovery with solar thermal integration for continuous cooling effect generation and applicable for space cooling purpose. The major findings of present work, the maximum irreversibility found in boiler as 47% in thermal power plant and solar generator as 12% of adsorption machine, whereas overall cooling effect from adsorption system is increasing by 15% in double bed combination. EES software is used for all analysis.
