The Security Implications of Virtual Local Area Network VLAN Niger Mills Calabar Nigeria

Virtual local area network (VLAN), is a logical grouping of network users and resources connected to administratively define the operation of activated ports on a switch. The creation of VLAN is saddled with the ability to develop smaller broadcast domain within a layer-2 switching router; by assigning different ports on the switch to different sub networks. The application was a re-design project carried out on the Niger-Mills’ network to improve the operational short falls identified b...

Modeling a low potency ipnetwork in Nigeria.

— Investigations have shown that interior places of the nation lacked capacity for high speed Internet usage; except the cosmopolitan sections. This article, therefore, conceptualizes a robust Broadband roadmap that can effectively deliver IP-wholesale and IP-retail services, through traffic convergence. The interconnect platforms are designed to ensure automatic re-routing of broadband traffic during link or node failure. The IP-wholesale services can be delivered to all main citie...

Kinetic studies of the biosorption of lead and zinc using tea leaf

Abstract: In this research work, Low-cost adsorbent was prepared from Camellia sinensis,physicochemical characteristics and the effective removal of Lead and Zinc from an aqueous phase were evaluated.The Camellia sinensis adsorbent precursor was characterized in terms of adsorbent dose, initial concentration and contact time. Aqueous phase adsorption studies were carried out under kinetic studies of pseudo first order, pseudo second order kinetics and the residue concentration of Lead and...

Computational studies of Sulphur trioxide and its protonated analogues

This article reports quantum chemical calculations on sulphur trioxide (SO3) and its protonated analogues (HSO3+and HOSO2+) by employing six different computational methods. This covers the simple Hatree Fock (HF) method, coupled cluster method, the Gaussian-4 (G4) compound method amongst others with two different basis sets (6-311++G** and cc-pVDZ). Optimized geometries, bond distance, rotational spectroscopy, dipole moment, proton affinity, vibrational spectroscopy and vibrational zero-...

Medicinal Chemistry Comparative Phytochemical Screening on Three Growth Stages of Pennisetum Pedicellatum Trin

A comparative preliminary study on the extraction and phytochemical profile of methanolic extracts of the leave, stem and root of pennisetum pedicellatum Trin at three growth stages (i.e stage 1, stage 2, stage 3) was carried out. The extracts were analysed to determine the presence of phytochemicals in the plant. The study revealed the presence of alkaloids, flavonoids, saponins and steroids. Tanins were found only in the stems of the plants and steroids were found only in the leaves....

SYNTHESIS AND PROPERTIES OF COPPER NICKEL SELENIDE (CuNiSe) THIN FILM BY CHEMICAL BATH DEPOSITION METHOD.

Abstract:Thin films of Copper Nickel Selenide (CuNiSe) were synthesized on glass slides at room temperature using chemical bath deposition (CBD) method. The films were deposited from aqueous solution containing copper ion, nickel ion and potassium selenate (K2SeO4) at varying molar concentration of nickel ion with constant time and pH of the reaction bath. The optical absorption data reveals that films of CuNiSe absorbs strongly at the ultraviolet range of 300 nm and has above 60%...

PRODUCTION OF POTASSIUM SALT (K2SO4) FROM AGRICULTURAL WASTE (UNRIPE PLANTAIN PEELS)

ABSTRACT The production of potassium salt K2­SO4 from unripe plantain agricultural waste was carried out. The sample randomly sourced from canteens located in Owerri West, Imo State. From the result of analysis carried out on the peels was found to contain highest level of K 2.55 ± 1.54 mg/g. other mineral component found were Na 159 ± 1.3 mg/g, Ca 101 ± 0.95 mg/g, Mg 75 ± 0.55 mg/g, Fe 5.8 ± 0.06 mg/g, P 36 ± 1.65. The yield of potassium sulphate, the target of this wor...

PROXIMATE AND CHEMICAL CHARACTERIZATION OF AFRICAN ELEMI NUTS

ABSTRACT The proximate compositions of African elemi nut were investigated by analyzing the moisture content, crude fat, ash content, crude fibre, crude protein and total carbohydrates in the nut. The associations of official analytical chemist (AOAC, 2000) methods were used. The values obtained from the proximate analysis were; moisture content (28.79%), ash (3.41%), crude fiber (2.84%), fat (30.42%), protein (8.40%), carbohydrate (26.14%). The GC-MS characterization revealed th...

AN INVESTIGATION INTO THE EFFECT OF FLOOD ON RADIOACTIVITY LEVEL OF WATER SEDIMENT IN MAKURDI RIVER BENUE STATE

In this work, the radiation monitor 4/4EC was used to measure radiations. The radiations in seven different locations were monitored and measured. The mean of all the readings were taken and subtracted from the background radiation and the radiological survey of the Makurdi River at seven different locations showed no gamma, beta and alpha measurements above typical background levels (5 to 25 at random intervals). The expected dose equivalence of the samples are within acceptable dose ...

EXTRACTION AND ISOLATION OF ALKALOIDS FROM ASYSTASIA GANGETICA (CHINESE VIOLET)

ABSTRACT Alkaloids are bioactive material mainly obtained from plant with pharmacological activities of one kind or another. The main aim of the present study was to extract and isolate alkaloid from Asystasia gangetica. The extraction of alkaloids from Asystasia gangetica was carried out with methanol using Soxhlet apparatus. Isolation was then followed by fractionating using acid and base in a separating funnel. The percentage alkaloid was determined and the phytochemicals screening ...

The use of Grimmen clay (TS-136) as a substitute for Geopolymer cement component``(Green Concrete)

AbstractThe term Geopolymer was introduced to represent the mineral polymers resulting from geochemistry. The process involves a chemical reaction under highly alkaline conditions on Si-Al minerals, yielding polymeric Si-O-Al-O bonds in amorphous form. The actual compressive strength of the concrete depends on various parameters such as the ratio of the activator solution to fly ash, molarity of the alkaline solution, ratio of the activator chemicals, curing temperature etc. In recent years, ...

EFFECT OF SWIMMING TRAINING ON COGNITIVE FUNCTION IN SCOPOLAMINE INDUCED DEMENTIA IN MICE.

ABSTRACTThe present study investigated the effects of a 2-week swimming exercise on scopolamine-induced dementia in a mice model. Thirty-two mice, were randomly divided into four groups (8 rats in each). Group A served as control without exercise and received saline only; Group B served as induced control and receive a single dose of scopolamine (1 mg/kg, i.p.) only on the last day; group C mice were subjected to short-term exercise (swimming) + single dose of scopolamine (1 mg/kg, i.p.) on t...
