WEB BASED PRODUCT E-COMMERCE RECOMMENDER SYSTEM USING A KNOWLEDGE CASE BASED ALGORITHM

Understanding customer needs is crucial to gaining and retaining customers in a web store, on online e-commerce applications. In order to ensure a versatile system for e-commerce, the pattern generated by customers when they click icons to select some particular products on an e-commerce website, based on their choice, ought to be studied, recorded and built-up into a database. Data mining techniques can then be applied in mining and analyzing information for this database in order to help wholesaler and retailers, improve sales, marketing strategies and product advertisement. In this paper, a conceptualized a framework for determining customers’ product choice and factors involved in choosing online commodities is proposed. The system is tailored for phone products

Student Web Self-Service Portal for a Tertiary Institution

The optimum condition for students to study is in an environment where they can access virtually all they need to know about courses, lecturers, locate places (for fresh and prospective students), validate staff identity, access past examination questions easily, identify vacant student hostels within and outside the school premises. Some of the reasons for students’ failure can be attributed to finding accommodation within or outside the school premises. Also, fresh students find it difficult to locate specific places in the university environment and some students find it very difficult to interact with staff. This paper presents a student self-service portal to address some of these challenges. Unified Modeling Language (UML) was used to model the system. The model was implemented using Microsoft C#, Microsoft ASP.net, Microsoft SQL Server, and Google Map. The proposed system was tested and the result obtained during the execution shows that the system is capable of addressing some of the challenges confronted by students.Keywords: Web Self-Service, Portal, Students, SQL, Unified Modeling Language (UML)

Covalent modification of reduced graphene oxide with piperazine as a novel nanoadsorbent for removal of H2S gas

In the present research, piperazine grafted-reduced graphene oxide RGO-N-(piperazine) was synthesized through a three-step reaction and employed as a highly efficient nanoadsorbent for H2S gas removal. Temperature optimization within the range of 30–90 °C was set which significantly improved the adsorption capacity of the nanoadsorbent. The operational conditions including the initial concentration of H2S (60,000 ppm) with CH4 (15 vol%), H2O (10 vol%), O2 (3 vol%) and the rest by helium gas and gas hour space velocity (GHSV) 4000–6000 h−1 were examined on adsorption capacity. The results of the removal of H2S after 180 min by RGO-N-(piperazine), reduced graphene oxide (RGO), and graphene oxide (GO) were reported as 99.71, 99.18, and 99.38, respectively. Also, the output concentration of H2S after 180 min by RGO-N-(piperazine), RGO, and GO was found to be 170, 488, and 369 ppm, respectively. Both chemisorption and physisorption are suggested as mechanism in which the chemisorption is based on an acid–base reaction between H2S and amine, epoxy, hydroxyl functional groups on the surface of RGO-N-(piperazine), GO, and RGO. The piperazine augmentation of removal percentage can be attributed to the presence of amine functional groups in the case of RGO-N-(piperazine) versus RGO and GO. Finally, analyses of the equilibrium models used to describe the experimental data showed that the three-parameter isotherm equations Toth and Sips provided slightly better fits compared to the three-parameter isotherms

Telmisartan as Monotherapy or add-on Therapy in African Hypertensive Patients

Background: There is a paucity of information on the effectiveness of angiotensin II-receptor antagonists in lowering blood pressure (BP) in black African hypertensive patients. This study was conducted to evaluate the antihypertensive effect, tolerability and safety profile of telmisartan, an angiotensin II-receptor antagonist, when given alone or as add- on therapy to adult African subjects with mild to moderate essential hypertension for a period of 12- 48 weeks. Methods: This study was part of a multicentre, multinational, open – labeled non-comparative trial of the efficacy and safety of telmisartan in controlling blood pressure of hypertensive patients. 30 adult Black African hypertensive patients were recruited into the study and after a 2 week placebo washout period, were given either 40mg or 80mg telmisartan once daily (OD) for a period of 48 weeks. Subjects whose BP was not controlled on the 80mg dose at 12 weeks were given either 2.5mg bendrofluazide OD or 50mg atenolol twice daily (BID). Primary study end –point was to determine the percentage of controlled responders using trough seated BP after 12 weeks. Systolic B

Clinical Evaluation of Ciprofloxacin Intravenous Preparation

The most common site of bacteria infection in humans is the urinary tract. For nosocomial infections it is the catheterized urinary tract. Compromised immune responses in hospitalized patients contribute to the difficulties encountered in treating their infections. In these patients, administration of intravenous antibiotic is usually the best treatment option available. The use of specific antibiotic therapy, according to sensitivity patterns in the particular environment is the base for cost- effective therapeutic measures used to safely treat moderate to severe infections and simultaneously prevent emergence of resistant strains in that environment. This study aimed at identifying the organisms causing bacterial urinary tract and soft tissue infection in hospitalized patients at the Lagos University Teaching Hospital and assessed the efficacy and tolerability of treatment with intravenous administered ciprofloxacin. 58 Patients (37 males, 21 females aged 19 to 76 years) participated in this open- labeled uncontrolled descriptive trial. The spectrum of organisms identified included an even mixture of gram-positive and gram-negative bacteria with staphylococcus aureus (37.9%) and pseudomonas aeruginosa (27.6%) being the most commonly occurring. 77.5% of the organisms were hospital-acquired with possible multiple drug resistance. Complete eradication of infection was achieved in 72.4% after 5 days of intravenous drug treatment. 14 days post treatment complete eradication rate was the same as success rate at 72.4%. On exclusion of pseudomonas aeruginosa infections, this percentage improved to 100% of treated patients In patients with complicated UTI, significant reduction of colony count occurred in 22.2% and complete eradication in 66.8%. These observations suggest that continuation of drug treatment beyond 5 days is necessary in complicated UTI or where pseudomonas aeruginosa is the infective organism. Adverse events were low at 1.7% indicating a good tolerability profile. We conclude that intravenous ciprofloxacin preparation is still efficacious and safe in the empirical treatment of bacterial urinary tract and soft tissue infections in the hospital setting Keywords: Infection, Urinary tract, Soft tissue, complete eradication, efficacious.NQJHM Vol. 14 (2) 2004: pp. 185-18
