Bacteria are capable of colonizing industrial processing surfaces creating biofilms on them which may adversely affect the quality and safety of products. Traditional cleaning-in-place (CIP) treatments using caustic and nitric acid solutions have been known to exhibit variable efficiency in eliminating biofilm bacteria. Here, we introduce enzymes as an alternative to traditional CIP treatments and discuss their mechanism of action against bacterial biofilms in cheese manufacturing. In addition, we discuss research gaps namely thermal stability, substrate specificity and residual activity of enzymes that may play a vital role in the selection of enzymes with optimal effectiveness against multi species biofilms. The outcome of this mini review will aid in the development of a novel and sustainable enzyme-based CIP treatment during cheese manufacturing in the future.

In the current scenario of Wireless Sensor Network (WSN), power consumption is the major issue associated with nodes in WSN. LEACH technique plays a vital role of clustering in WSN and reduces the energy usage effectively. But LEACH has its own limitation in order to search cluster head nodes which are randomly distributed over the network. In this paper, ERA-NFL- BA algorithm is being proposed for selects the cluster heads in WSN. This algorithm help in selection of cluster heads can freely transform from global search to local search. At the end, a comparison has been done with earlier researcher using protocol ERA-NFL, which clearly shown that proposed Algorithm is best suited and from comparison results that ERA-NFL-BA has given better performance.

Aim/Purpose: This paper presents a study of Virtual Communities of Practice (VCoP) evaluation methods that aims to identify their current status and impact on knowledge sharing. The purposes of the study are as follows: (i) to identify trends and research gaps in VCoP evaluation methods; and, (ii) to assist researchers to position new research activities in this domain. Background: VCoP have become a popular knowledge sharing mechanism for both individuals and organizations. Their evaluation process is complex; however, it is recognized as an essential means to provide evidences of community effectiveness. Moreover, VCoP have introduced additional features to face to face Communities of Practice (CoP) that need to be taken into account in evaluation processes, such as geographical dispersion. The fact that VCoP rely on Information and Communication Technologies (ICT) to execute their practices as well as storing artifacts virtually makes more consistent data analysis possible; thus, the evaluation process can apply automatic data gathering and analysis. Methodology: A systematic mapping study, based on five research questions, was carried out in order to analyze existing studies about VCoP evaluation methods and frameworks. The mapping included searching five research databases resulting in the selection of 1,417 papers over which a formal analysis process was applied. This process led to the preliminary selection of 39 primary studies for complete reading. After reading them, we select 28 relevant primary studies from which data was extracted and synthesized to answer the proposed research questions. Contribution: The authors of the primary studies analyzed along this systematic mapping propose a set of methods and strategies for evaluating VCoP, such as frameworks, processes and maturity models. Our main contribution is the identification of some research gaps present in the body of studies, in order to stimulate projects that can improve VCoP evaluation methods and support its important role in social learning. Findings: The systematic mapping led to the conclusion that most of the approaches for VCoP evaluation do not consider the combination of data structured and unstructured metrics. In addition, there is a lack of guidelines to support community operators’ actions based on evaluation metrics.

Four starch-encapsulated formulations of EPTC(S-ethyl dipropylthiocarbamate) and of butylate(S-ethyl diisobutylthiocarbamate) were prepared and evaluated by comparison with their respective emulsifiable concentrate formulations for their slow-release capabilities and efficacies. Chemical and biological evaluation indicated that difference in controlled-release could be achieved by the selection of the starch xanthate and oxidant used in the formualtion process. EPTC and butylate released slower when formulated as starch-encapsulated granules than when formulated as emulsifiable concentrates under soil conditions that favored rapid release. The initial release was adequate for weed control and slow enough for desired residual activity. Repeated seeding and harvesting the treated soils and bioassays of treated soils generally produced release rate anticipated from short term dry and wet chemical tests.

In a democratic process voting plays a vital role in selection of policy as well as candidates. Voting though gives the freedom to voter to cast his opinion it is not free fraudulent. In order to have secure voting and convey the opinion of authorized voter in this paper we have presented a java based framework for fraud proof electronic voting system. In this framework we ensure that only the authorized voter is permitted to cast his vote and mitigate illegal voters cast votes on faking or pretending to be someone else. Proposed FPF provides a multi-level of authentication mechanism to validate the voter. The proposed system is tested for efficiency and robustness in comparing it with the existing system and is found to be efficient through comparative analysis. At present FPF is successful in mitigating the unauthorized voting further enhancement in the electronic voting system is being carried out as future work.

This descriptive study explores the impact of washback on ESL students’ performance at secondary level. In this study, the term “washback” refers to the test effect on content of curriculum, learning English, teaching and the activities conducted in classroom. The factors other than the test itself may affect positive washback; lack of positive washback does not make test invalid whereas the negative washback effect occurs when there is lack of construct validity of test. Test design and validity plays vital role in achieving positive washback (Messick, 1996). The study aims to investigate the effects of positive washback and benefits in learning and teaching processes in ESL classrooms, while negative washback effects are destructive and can be a hindrance in achieving the goals in ESL classrooms. Recent research is descriptive in nature and survey based method was adopted for this study. 50 teachers were selected by using purposive sampling technique and 100 students were selected by using simple random sampling technique. Three tools were used for this study including: Questionnaire, Test and Observation checklist. The findings of the study exhibit that negative washback effect has its influence on tests, learning and teaching. The study concludes with a realization of the fact that language pedagogy is affected by washback. However, it is claimed by majority of the teachers that washback affects the selection of teaching methods because exams stress brings pressure and it becomes necessary for English teachers to develop linguistic competence in their students. For future researches it is recommended that other studies should be made in order to find out the impact of washback on the strategies adopted by learners while learning second language.

AbstractIn the recent years, awareness has risen by an increasing number of researchers that we need studies that appropriately model the complexity of school improvement if we want to increase our knowledge about school improvement substantially and to close the identified research gaps within this field (Feldhoff T, Radisch F, Klieme E, J Educ Admin 52(5):565–736, 2014; Hallinger P, Heck RH, School Effect School Improv 22(2):149–173, 2011; Sammons P, Davis S, Day C, Gu Q, J Educ Admin 52(5):565–589, 2014). So far, respective quantitative studies, that appropriately consider those complexities, have hardly been realized because of the high efforts of current methods and costs involved (Feldhoff T, Radisch F, Bischof LM, J Educ Admin 2(54):209–240, 2016). It is, therefore, apparent to look for new, innovative methods that can adequately take into account the complexity of school improvement. For a reasonable search and selection of innovative methods, it is necessary to describe the systematic complexity of school improvement and the resulting requirements for the methods in more detail. This is a central goal in this chapter. For this reason, we present our framework of complexity. We then formulate questions that will prompt the reader to reflect critically upon the methods in general and especially in this volume.
