Utilisation of Scrubbing Machines for Hospital Cleanliness in Tertiary Care Medical Institute of North India[]


Hospital cleanliness is very important for any hospital. Whereas, developed countries use automated cleaning equipments, but resource constraint countries struggle to decide whether investment in the automated equipment for cleaning for example scrubbing machines, is worth? This observational and record review study was done to study the impact of automated scrubbing machines on the hospital floor cleanliness and to assess the utilization, maintenance and operational problems of these scrubbing machines. A cross-sectional study of eight automated scrubbing machines was carried out in 979 bedded tertiary care hospital. The machine utilization, breakdown indices were recorded by logbook analysis and observation of floor cleanliness was done using pre-tested score sheet. Health care providers and the patients were interviewed to assess their perceptions about hospital cleanliness.


Comparative Cytogenetic Study of Exfoliative Oral Mucosal cells in Tobacco related Potentially Malignant Disorders in a South[]


Accumulation of genetic alterations induced by the genotoxins by present in betel quid and tobacco leads to oral potentially malignant disorders (PMDs). High levels of malignant transformation of PMDs have been well doc-umented. Micronucleus (MN) assay in exfoliated buccal cells of tobacco related oral PMDs appears to be one of the most suitable tests to assess the toxic effects of various carcinogens in humans. Thus the study was under-taken to observe the cytogenetic damage in the exfoliate buccal cells of tobacco related PMDs and control sub-jects by MN count. The MN count was analyzed in the exfoliate buccal cells of 15 PMDs patients, of which 8 belonged to leukoplakia (LPK) and 7 to Sub Mucosal Fibrosis (SMF) and compared with the 15 healthy con-trols. The Mean MN count was scored to estimate the genotoxic damage. The mean and SD values of the MN count of the PMDs were 113.06 ± 17.44 (3.76% ± 0.58% and in controls it was 13.08 ± 5.27 (0.44% ± 0.17%). The students‘t’ test for the MN count between the cases and the controls showed a significant P value (< 0.001). The elevated MN count indicates thatthe study group belongs to a high risk population for oral cancer. This scientific evidence can be used in support of national campaigns to prevent PMDs from progressing to malignant cancer, by devising intervention strategies and subsequent disease managements to reduce the morbidity and mortality associated with tobacco related oral PMDs.


CHALLENGES FACING LABORATORY PRACTICAL APPROACH IN PHYSICS INSTRUCTION IN KENYAN DISTRICT SECONDARY SCHOOLS[]


Over the years, the Kenya National Examination Council’s (KNEC) secondary school Newsletters have repeatedly pointed out that students need to be exposed to more and more laboratory practical activities in all sciences throughout their secondary school period in order to realize improved performance. As such this study aimed at establishing the challenges facing laboratory practical approach in Physics instruction in the district category of schools in Kenya. KNEC newsletters further show that most schools in this category perform way below average in Physic examination. The study was based on constructivist experiential learning theories which explain learning as being constructed through tangible activities. In secondary school Physics instruction these theories focus on laboratory practical activities. The findings of the study provide a bearing on how best to overcome the challenges.

Conveyor Control Using Programmable Logic Controller[]


A programmable Logic Controller (PLC) is a specialized computer used for the control and operation of manufacturing process and machinery. It uses a programmable memory to store instructions and execute functions including on/off control, timing, counting, sequencing, arithmetic, and data handling. Programmable Logic Controllers (PLC) is used in almost every aspect of industry to expand and enhance production. Where older automated systems would use hundreds or thousands of electromechanical relays, a single PLC can be programmed as an efficient replacement. The functionality of the PLCs has evolved over the years to include capabilities beyond typical relay control. Sophisticated motion control, process control, distributive control systems, and complex networking have now been added to the PLC’s Functions. Therefore, PLCs provide many advantages over conventional relay type of control, including increased reliability, more flexibility, lower cost, communication capability, faster response time and convenience to troubleshoot. The paper is based on systematic conveyor controller programming by programmable logic controller using omron software which is a world smallest plc, offers variety of expansion options and has user-friendly software.

A Survey of Load Balancing Algorithms using VM[]


Cloud Computing is an emerging computing paradigm. It aims to share data, calculations, and service transparently over a scalable network of nodes. Since Cloud computing stores the data and disseminated resources in the open environment. So, the amount of data storage increases quickly. In the cloud storage, load balancing is a key issue. It would consume a lot of cost to maintain load information, since the system is too huge to timely disperse load. Load balancing is one of the main challenges in cloud computing which is required to distribute the dynamic workload across multiple nodes to ensure that no single node is overwhelmed. It helps in optimal utilization of resources and hence in enhancing the performance of the system. A few existing scheduling algorithms can maintain load balancing and provide better strategies through efficient job scheduling and resource allocation techniques as well. In order to gain maximum profits with optimized load balancing algorithms, it is necessary to utilize resources efficiently. The main aim of this paper is to discuss some of the existing load balancing algorithms in cloud computing environment.

CORRUPTION IN INDIA AND FIGHT AGAINST CORRUPTION: LOKPAL BILL[]


All of us are aware of the fact that the country, which we love so much has been in the clutches and the diabolical jaws of the virus, called corruption. Corruption in India is the main cause of its every failure. Every developmental project and the defense requirements are being over shadowed by the corrupt officials. Even the magistrates who are believed to be the axis of the law are corrupted to such an extent that millions of cases are pending for the last few years. Political corruption is the use of powers by government officials for illegitimate private gain. An illegal act by an officeholder constitutes political corruption only if the act is directly related to their official duties, is done under color of law or involves trading in influence. Forms of corruption vary, but include bribery, extortion, cronyism, nepotism, patronage, graft, and embezzlement. Corruption may facilitate criminal enterprise such as drug trafficking, money laundering, and human trafficking. This research paper illustrate about corruption and necessity of lokpal bill against corruption


Effect of admixtures on the physical properties of non-autoclaved light weight blocks using pond ash[]


In the present study effect of activator calcium chloride and superplasticizer on the compressive strength and demoulding time of light weight non-autoclaved blocks has been studied. De-moulding time has been reduced from 48 hrs. to 8-10 hrs. With 1% activator and superplasticizer further reduction in de moulding time by 2 hrs. and increase in compressive strength has been observed. Petrography study of inner surface of block has shown distribution of air entrainment. Overall thermal transmission (U) value of the blocks of different densities has also been determined. It is noticed that U value is increasing with enhancement of densities and vice - versa.


A Winning Governance Structure: Basic components of a corporate governance structure that supports a winning corporate strategy and enterprise value enhancement[]


Corporate governance structure describes the arrogation of rights and responsibilities to key agents in the corporation, as well as the rules and procedures of engagement in corporate affairs. The governance structure also allows for the enactment of code of conduct, strategies and decisions of corporations. Some of the components of a corporate governance structure include shareholders, board of directors, characteristics of the board, board committees, management and the various levels of engagement and interactions amongst them. The size, characteristics, composition and interaction of these corporate ac-tors determine the effectiveness of the overall governance structure and hence firm performance.


The Role of Shareholders in Executive Compensation: Theoretical underpinnings and practical analyses of the Swiss Referendum on the extent of shareholder involvement in executive compensation.[]


Executive compensation is significantly increasing in countries where there is a low level of restriction or regulation on the subject matter. The debate as to whether the owners (shareholders) of the companies should get involved in the determination of compensation for executives is still inconclusive. Some researchers and practitioners are of the view that board members who have oversight responsibility over the corporate governance system must be left to determine the executive compensation and that the State should not interfere in the work of companies. Others however believe that the State has responsibility towards providing a conducive business environment for companies, including shareholders’ rights and assets.

COMPRESSIVE BEHAVIOUR OF SISAL FIBRE REINFORCED TERNARY CONCRETE AT ELEVATED TEMPERATURES[]


The utilization of pozzolanic materials such as fly ash (Fa) and calcined waste crushed clay bricks (CWCCB) as binders in ternary mixtures and the application of sisal fibre as reinforcing agent in ordinary Portland cement (OPC) concrete has received attention in recent years. Little is known about the mechanical behaviour of these new composites when exposed to elevated temperatures. In this study, the compressive performance of four categories of 150mm concrete cube specimens were considered comprising; (1) Control mix consisting of plain OPC concrete of 1:2:4 mix ratio ( one part OPC, two parts fine aggregate and four parts coarse aggregate). (2) Concrete specimens as in (1), but reinforced with 3% volume fraction of 40mm average length sisal fibre. (3) Ternary mixtures of OPC, Fa and CWCCB at ratios of 50%, 30% and 20% of total binders respectively, with same fine, coarse aggregate and sisal fibre content. (4) Ternary mixtures of OPC, Fa and CWCCB at ratios of 50%, 20% and 30% of total binders respectively, also with same fine, coarse aggregate and sisal fibre content. Water/binder ratio for all mixtures was fixed at 0.6. The 150mm concrete cube specimens were cured, dried and subjected to varying elevated temperatures of 100, 150, 200, 300, 400 and 600°C for exposure duration of 2 hours each. The results revealed that between temperatures of 100°C and 600°C, the ternary concrete specimen with 30%Fa and 20%CWCCB showed good thermal stability but recorded a 24% reduction in compressive strength at elevated temperatures of 600°C compared with all the specimens. The ternary concrete with 30%Fa and 20%CWCCB is recommended for structural elements requiring thermal stability.


PERFORMANCE EVALUATION OF SISAL FIBRE AS REINFORCING AGENT IN MEDIUM STRENGTH TERNARY CONCRETE[]


There is growing trend worldwide in the research and development of sustainable low-cost, atoxic, renewable and durable construction materials. Tropical countries like Nigeria are known to be the domain of vegetable fibres and other non-pyroprocessed industrial by-products that possess cementing properties (pozzolanas). Sisal fibre has emerged as reinforcing material in polymers used in civil industries and other products and has the potential to be cultivated in luxurious abundance in Nigeria. This paper reports the experimental study on use of locally sourced and processed sisal fibre as reinforcing agent in ternary of fly ash (Fa) and calcined waste crushed clay bricks (CWCCB), normal strength, OPC concrete. In this work, the physical and chemical characteristics of sisal fibre, Fa and CWCCB are obtained. The amount of OPC in the ternary mixtures was fixed at 50%, while the ratio of fine to coarse aggregate was fixed at 1:2. The mechanical performance of concrete samples in three ternary blends of Fa and CWCCB in the ratios of 20/30, 25/25 and 30/20, incorporating 3% volume fraction of 40mm average length of sisal fibres as reinforcing agent were evaluated. It was shown that concrete samples incorporating 3% volume fraction of sisal fibre and containing 30%Fa + 20%CWCCB(4F30/20), gave the best mechanical performance.

Sharing of knowledge in the construction organisations is become necessary, as it certainly leads to knowledge application, innovation, as well as a competitive advantage for the construction organisations. Thus, technological devices are used for information and knowledge dissemination in the business organisation. Therefore, this paper examines the significant influence of technological device on knowledge sharing practice in the construction organisation. The questionnaire survey approach was adopted, due to the type of data required. A total of 350 questionnaires were distributed to Engineers, Quantity Surveyors, Architect, Foremen and other stakeholders. Analysis of variance (ANOVA) and descriptive analysis were adopted for data analysis. The results show that the followings technological devices have influence on knowledge sharing practice: email, internet, 4D simulation, video conference, online chatting, mobile phone, facebook, desk and laptop, fax machine, electronic billboard and cellular phone. In view of the above, the paper suggests that the management of the construction companies should encourage the use of technological device on knowledge sharing practice in order to have effective dissemination and storage of knowledge.


Realizing the power of Emotional Intelligence by altering the leadership skill[]


Emotional Intelligence is the ability to utilize power, information and energy in our emotions by knowing, choosing, navigating and managing them to lead a more effective life. Each individual possess different leadership skills, but in order for individuals to become effective leaders, they’ll need a high level of emotional intelligence. In today’s workplace, it has become a highly important factor for success, influencing productivity, efficiency and team collaboration. R.Gopinath (2011) argues that work place emotions can play a major role in the leadership success. He opines that “Emotional Intelligence contributes to effective leadership in organization by focusing on five essential elements of leader effectiveness: development of collective goals and objectives; instilling in others an appreciation of the importance of work activities; generating and maintaining enthusiasm, confidence, optimism, cooperation and trust; encouraging flexibility in decision-making and change, and establishing and maintaining a meaningful identity for an organization. Hence the present paper discusses the relevance of emotional intelligence for leadership success by examining the findings of existing literature. Keywords: Emotional Intelligence, Leadership
