Library computerization projects at Nimbe Adedipe library, University of Agriculture, Abeokuta and Keneth- Dike Library, university of Ibadan were evaluated. The total population of the respondents was 331 which include two university librarians, twenty-two library staff and two hundred users. The data collection instruments used for this study were a questionnaire and interview. The instruments were structured to identify important measurable variables associated with the provision and utilization of library computerized services. Out of 200 copies of questionnaire administered to the users, only one hundred and ninety two were completed and used for the study. The data collected was analyzed using descriptive statistics involving tables and simple percentages. Based on the questionnaire survey of the library staff and the interview granted by university librarians, the information technology resources in the university libraries were inadequate for successful implementation of the library computerization project, however, computerized services such as CD-ROM services, internet search online journal subscription proved by the libraries have tremendous impacts on the organization, management and dissemination of information. There was a low number of satisfied users which was an indication that much remain to be done to fully grow the automated information services profiles in the university libraries.

The research aims to highlight the importance of maintenance in general and the maintenance of school buildings, in particular, to identify the problems and constraints of maintenance of school buildings and the extent of follow-up schools and authorities competent departments in the perpetuation of educational facilities to ensure its functionality and maintain the integrity of the building and the level of comfort to the user through an elected sample intentional architectures school implemented by the Ministry of Education or on behalf of, where the research contained the first two parts of data collection and recording observations, as well as data obtained from the survey of school buildings and personal interviews of specialists from the teachers and the administration of Engineers personnel and gentlemen in school buildings department and the second part questionnaire that were distributed to the elected school principals, showed the results of the analysis of data from many weaknesses in practice maintenance system, including administrative and planning and organizational side and the lack of engineering staff with competence and experience and good performance and a lack of honesty in the use of high quality materials.

Bladder cancer is the second urogenital cancer; smoking represents the main risk factor for its occurrence. Urothelial bladder tumors without muscle infiltration are a group of tumors treated with conservative endoscopic resection, often associated with adjuvant instillations of chemotherapy or immunotherapy. The high risk of recurrence leads to a systematic monitoring. Cystoscopy represents the standard of monitoring. Prognosis of this tumor group is heterogeneous. The risk of progression to invasive cancer is highly variable and potentially lethal. Stage and tumor grade are well recognized as prognostic factors. Cystectomy may be considered in high-risk tumors, in case of failure of conservative treatment. The purpose of this article is to analyse through a literature synthesis, prinicipal topics concerning diagnosis, treatment and follow-up of non-infiltrating bladder tumors.

The mastoid region is favourable for sex determination, as it is the most protected region and resistant to damage due to its anatomical position at the base of the skull. The skull is traditionally considered to be the best skeletal indicator of ancestry and the second best indicator of sex next to the pelvis. The objective of this study is to verify the efficacy of a new method for determination of sex of fragmentary human skeletal remains in the native state of U.P., India. Knowledge of sex estimation through mastoid process is important for Anatomist, physical and forensic anthropologists.

Wet Chemical Synthesis method was used to synthesis Ni doped ZnS and undoped ZnS. The as-prepared products were characterized using XRD, FE-SEM, UV-VIS and PL analysis. The crystal structures, morphologies and optical properties of as-prepared samples along with the particle size, micro strain and dislocation density have been investigated. The results exhibit a crystalline hexagonal structure in particles, rod shape size about 2nm and optical bandgap of 5.56 ev.

There has been tremendous growth in wireless technology in the last decade. This advancement has changed people do business in mobile environment (M-Business). This is where M-Commerce or Ubiquitous Commerce (U-Commerce) step in which promises to allow shoppers to purchase goods and have services using mobile phones, wearable PCs and handhelds and in the same way brings challenges for both individuals and society. This paper is intended to bring out the facts about the feasibility of M-Commerce today; the strength and opportunities, the weaknesses and threats lying ahead. The highlight of this paper is to explore the issues that arise from the effects of M- commerce and the challenges lying ahead from which in future, the researchers may spell-out the ways to serve M- commerce as drivers of the growing market demand in the long-term.

Our aim in this paper is to investigate the commuting property of the Traces of a Symmetric Biderivations on prime and semiprime ring R. Furthermore, we look for the commutitivity of a ring R under some suitable conditions.

Let L be a finite lattice. A sublattice K of a lattice L is said to be convex if a,b K; c L, a c b imply that c K. Let CS(L) be the set of convex sublattices of L including the empty set. Then CS(L) partially ordered by inclusion relation, forms an atomic algebric lattice. Let P be a finite graded poset. A finite graded poset P is said to be Eulerian if its M bius function assumes the value (x; y) = (-1)l(x;y) for all x y in P, where l(x, y) = (y)- (x) and is the rank function on P. In this paper, we prove that the lattice of convex sublattices of a Boolean algebra Bn, of rank n, CS(Bn) with respect to the set inclusion relation is a dual simplicial Eulerian lattice. But the structure of the lattice of convex sublattices of a non- Boolean Eulerian lattice with respect to the set inclusion relation is not yet clear.

In this world of technology and scientific development, there has been great need to intensify researches on the development of security alarming systems in our agricultural farms and farmsteads. The pressure mat auto-light (PMAL) security control system is a sensory device consisting of two separate sensory units (Pressure Mat (PM) unit and Auto-Light (AL) unit) integrated into an efficient single sensory security system. It is designed and constructed with mat transmitter (MT) under a foot mat signaler receiver (FMSR) 12V, 223A buzzer, light emitting diode (LED), integrated circuit (IC), transistor (L8050), LM358N op-amp, a 2-1.5V battery, and resistors of 0.5? and 4.5? served as signaler receiver (SR), Light Dependent Resistor (LDR), a relay of 1000mA, 1000W/12V power transformation and power source of 220V to 240V. Efficiency of 70%, 95.8% and 90% for the frequency of loop gain , transmitter ( ) and receiver ( ) circuits respectively showed reliability of the PMAL designed and constructed. From evaluation and testing of the device, the receiver can sense any pressure or weight upon the triggering spring at a distance 150m away from its area of installation, within which the buzzer beeps (sounds out), signaling wave presence in the receiver unit, thereby alerting the presence of intruder(s) in farmstead(s) and thus automatically shut-close the farmstead with the aid of a LDR, so that wild animals such as fox, jackals, wolfs etc will be kept away from fields of forest nursery and confined animals.
