1. QUALITY STANDARDS: PANACEA FOR A SUSTAINABLE DEVELOPMENT OF SMALL HYDROPOWER PROJECTS IN NIGERIA
by A.A Yekinni, G.G Bajela & S.K Bello
Abstract

Sustainably developed and managed small hydropower has enormous potential to contribute to sustainability energy goals. To achieve this, the International Hydropower Association (IHA) has developed Sustainability Guidelines, and an associated Compliance Protocol that provides a clear framework for good practice. Also, quality standards for small hydropower have been developed for countries like India, Sweden, Brazil, USA, Canada etc taking into consideration there local environments. Since prospects for Small Hydro Power (SHP) in Nigeria have led to increase in number of SHP local consultants and SHP equipment manufacturers, the need to defining quality standards for hydro power development in Nigeria is inevitable.  Therefore the Small hydropower quality standards has been suggested in this paper to define the quality requirements of SHP projects in the areas of planning, design, supply and installation works in Nigeria. This is to ensure competitive bidding of SHP projects that will guarantee quality finish and performance. For a speedy and successful development of small hydropower, use of standards and guidelines in planning, designing and execution is necessary. A general awareness of the codes, standards and guidelines, especially for small hydropower projects is also emphasized.  For quality assurance of the small hydropower stations, establishment of a special hydropower research institute in Nigeria has been suggested to initiate performance testing of any hydropower project.

3. ROUTE OPTIMIZATION OF STACKER IN AUTOMATED STORAGE AND RETRIEVAL SYSTEM BASED ON HYBRID ALGORITHM
by YANG Jin,MA Bin-liang & Ma Liang
Abstract

 

This paper try to solve the route optimization of stacker in automated storage and retrieval system with the hybrid algorithm which based on the combination of genetic algorithm and particle swarm optimization. First the algorithm generates the initial population by using particle swarm algorithm. And then the population undertakes assorted crossover and mutation in the iterative process by using genetic algorithm. In the end the algorithm can achieve very good results by testing the example.

4. HYDROCHEMICAL COMPOSITION AND IRRIGATION WATER QUALITY OF LERMA-CHAPALA RIVER SYSTEM, MÉXICO

by José Pedro Pérez Díaz, Héctor Manuel Ortega Escobar, Álvaro Can Chulim, Edgar Iván Sánchez Bernal, Carlos Ramírez Ayala & Ebandro Uscanga Mortera

Abstract

The Lerma River originates in the Almoloya lagoon, in Mexico State. It is 750 km. long and belongs to the Lerma-Santiago-Pacífico basin, one of the most important in Mexico due to its intense agricultural and industrial activity. To carry out this research, during the summer and autumn of 2013, water samples were collected and analyzed from 39 sampling stations the Lerma-Chapala river system. The objective was to know the hydrochemical composition and agronomic quality of the water in the Lerma river and lake Chapala through the determination of variables: Ca2+, Mg2+, Na+, K+, CO32-, HCO3-, Cl-, SO42-, total dissolved solids (TDS), hydrogen potential (pH), electrical conductivity (EC) and sodium adsorption ratio (SAR). The results indicated that the type of water is sodic-bicarbonated and mixed-bicarbonated, which was attributed to the discharges of wastewater and the water supply from tributary rivers in the Lerma-Chapala Basin. The concentration of TDS was low (< 674 mg L-1). The EC displayed values between 0.307 and 1.129 dS m-1, which is why, in 66.6% of the sampling stations, water has no use restriction for agricultural irrigation. SAR average was 2.2 meq L-1; the joint EC-SAR values suggested the classification of water as C2-S1 (74.4%) and C3-S1 (25.6%), indicating its suitability for agricultural irrigation.

5. CLASSIFICATION OF FULLERENES WITH HEPTAGONAL RINGS ACCORDING TO BOUNDARY FACES
by F.J. Sánchez-Bernabe & Javier Salcedo
Abstract

According to Fowler and Manolopoulos [1], classical fullerenes are those carbon cage molecules with exactly 12 pentagons and n/2 - 10 hexagons. All classical fullerenes satisfy the so called isolated pentagon rule IPR, Kroto [2]. On the other hand, nonclassical fullerenes are those carbon cage molecules, such that one or more squares or heptagons, appears. In this last case, sometimes pentagon-pentagon adjacencies are observed, and the most stable structure are related with the least pentagon-pentagon adjacencies, which is known as the pentagon adjacency penalty rule PAPR, Campbell et al [3]. Work has been done to study nonclassical fullerenes; for example, Ayuela et al [4] show theoretical evidence for the existence of a nonclassical fullerene C62 with one heptagonal, 13 pentagonal and 19 hexagonal rings. Jie An et al [5] studied the isomers of fullerene C26  composed of square, pentagonal, hexagonal, and heptagonal faces. Also, Tchoffo et al [6] present fullerenes with square and octagonal faces. Furthermore, Li-Hua Gan et al [7] study fullerenes C46, C48, C50, and C52, some of them composed of one heptagonal ring. Finally, D.-L. Chen et al [8] study fullerene C58.
