Literatures indicate that service management has become a strategic issue for companies in the new millennium. By improving logistics service quality (LSQ), logistics companies can increase customer satisfaction (CS) and gain market shares. This study aims to establish a logistics service attributes analysis model to extract customer knowledge for logistics service quality improvement based on ...

This research describes photo degradation of direct red 81(5-solamin) in the presence of zinc oxide nano-sized catalyst supported on granule glass under UV light irradiation. The effects of some parameters such as various pH and different atmosphere on photo degradation efficiency were studied. After various experiments it was revealed that among various atmospheres, at neutural medium, oxygen ...

Given a weighted graph, let W 1 ; W 2 ; W 3 ; : : : denote the increasing sequence of all possible distinct spanning tree weights. Settling a conjecture due to Kano, we prove that every spanning tree of weight W 1 is at most k ? 1 edge swaps away from some spanning tree of weight W k. Three other conjectures posed by Kano are proven for two special classes of graphs. Finally, we consider the al...

BACKGROUND Lymphadenopathy is a common clinical problem here in Kano, Northern Nigeria but there has been no formal study. We therefore undertook this review to evaluate the pattern in our locality. METHOD This is a seven-year (1998-2004) retrospective review of all histologically diagnosed lymph node biopsies received at Aminu Kano Teaching Hospital, Kano. RESULTS Cervical, axillary and in...

Milk is a very important component of human diet. The presence of toxic element in milk may create significant health problems. In this study, metal levels of fresh cow milk were determined. Fresh milk samples were collected from 17 cows grazed around challawa industrial estate, Kano and 9 cows grazed on open fields in Zaria, Kaduna state. Metal levels were determined using Atomic Absorption Sp...

Background and Purpose: Aspergillosis is one of the most common opportunistic fungal infections in immunocompromised and neutropenic patients. Aspergillus fumigatus (A. fumigatus) is the most common causative agent of this infection. Due to variable CO2 concentrations that pathogens are exposed to during the infection process and to understand the role of CO2, we examined the effects of various...
