Approaches to teaching: Current opinions and related research

Three approaches to teaching and learning are introduced. Each approach has its relative merits and disadvantages. Ideally, each approach should not be used in isolation. The use of facilitatory approaches to teaching and learning should be encouraged to assist the development of problem solving, decision making skills and creative and critical thinking in nurses, particularly those studying on competency-based education and training courses and programme

Self-machinery?: steel trusses and the management of ruptures in eighteenth-century Europe

Abstract: Effectiveness Of Rice Husk Ash And Poly Aluminum Chloride In Reducing Exposure Colour Liquid Waste Industry Sasirangan. Sasirangan fabric industry is the textile of industry in Kalimantan Selatan produce wastewater of dyeing cloth sasirangan process that uses water as a primary adjuvant in stage process.The study aims to determine the effectiveness of rice husk ash and Poly Aluminium Chloridereduce levels of dyes in wastewater sasirangan "Oriens Handycraft". This study tested a laboratory scale with dose variation of rice husk ash and Poly Aluminium Chloride for reduced levels of dyes in wastewater sasirangan. The study design is a randomized pretest - posttest control group design. The population of the waste liquid fabric manufacturesasirangan results and samples are the waste from the manufacture of cloth sasirangan which represents the population. This study conduct statistical tests usingKruskal Wallis and Mann-Whitney Test.Theresultsofthestudyof color levels priorto treatment equal to 2,712 PtCo and after treatment ranges from 676.3 to 978.7 PtCo at a dose of 58 grams of rice husk ash; 59 g; 60 g; 61 g; 62 gr and Poly Aluminium Chloride 0.5 gr. For a dose of 58 grams of rice husk ash; 59 g; 60 g; 61 g; 62 gr and Poly Aluminium Chloride 1 g of color levels before treatment and after PtCo 1775 amounted to 227.7 PtCo ranges up to 240 PtCo. Rice husk ash and Poly Aluminium Chloride effective at pH 6.5 - 7. Results of normality test showed abnormal data. Kruskal Wallis test probability value 0.002 <0.05, there is a difference between the average dosing in the control group and the treatment group and the Mann-Whitney Test probability value of 0.009 (0.018 <0.05), the rice husk ash dosing and Poly Aluminium Chloride 1 g more effective than rice husk ash dosing and Poly Aluminium Chloride 0.5 g.Efforts government can do is provide the appropriate policy on effluent quality standards and attention to industrial waste disposal sasirangan. For the industry can manage its waste before waste into the environment. Keywords: SasiranganWaste; Materials coagulant; pH; Dye

The feasibility and effectiveness of a web-based personalised feedback and social norms alcohol intervention in UK university students: A randomised control trial

OBJECTIVE Alcohol misuse amongst University students is a serious concern, and research has started to investigate the feasibility of using e-health interventions. This study aimed to establish the effectiveness of an electronic web-based personalised feedback intervention through the use of a randomised control trial (RCT). METHODS 506 participants were stratified by gender, age group, year of study, self-reported weekly consumption of alcohol and randomly assigned to either a control or intervention condition. Intervention participants received electronic personalised feedback and social norms information on their drinking behaviour which they could access by logging onto the website at any time during the 12-week period. CAGE score, average number of alcoholic drinks consumed per drinking occasion, and alcohol consumption over the last week were collected from participants at pre- and post-survey. RESULTS A significant difference in pre- to post-survey mean difference of alcohol consumed per occasion was found, with those in the intervention condition displaying a larger mean decrease when compared to controls. No intervention effect was found for units of alcohol consumed per week or for CAGE scores. Sixty-three percent of intervention participants agreed that the feedback provided was useful. Those intervention participants who were above the CAGE cut off were more likely to report that the website would make them think more about the amount they drank. CONCLUSIONS Delivering an electronic personalised feedback intervention to students via the World Wide Web is a feasible and potentially effective method of reducing student alcohol intake. Further research is needed to replicate this outcome, evaluate maintenance of any changes, and investigate the process of interaction with web-based interventions

Complete Genome Sequences of Mycobacterium smegmatis Phages Chewbacca, Reptar3000, and Riparian, Isolated in Las Vegas, Nevada

Here, we present the complete genome sequences of Mycobacterium smegmatis phages Chewbacca, Reptar3000, and Riparian, isolated from soil in Las Vegas, NV. The phages were isolated and annotated by undergraduate students enrolled in the Phage Discovery course offered by the School of Life Sciences at the University of Nevada, Las Vega

Structure and diversity of fish communities in man-made ponds of the Niger Delta (southern Nigeria)

1. A survey of eight local earthen hand-dug ponds located within the freshwater swamps of a Niger Delta area&nbsp;(southern Nigeria) was conducted over a period of 3 months. A total of 4,313 fishes representing 19 species&nbsp;from 12 families were recorded.2. The most abundant species was Xenomystus nigri (905 individuals), whereas the least common was Protopterus&nbsp;annectens (13). Cichlidae and Clariidae counted three species each, whereas Anabantidae, Hepsetidae,&nbsp;Mochokidae, Protopteridae, Phractolaemidae, Malapteruridae and Gymnarchidae were represented by a single&nbsp;species each.3. A lotic species, Synodontis sp., was recorded possibly as a result of the episodic flood of 2012.4. The Engenni swamps harbour a moderately diverse ichthyofauna. Regulations should be put in place to further&nbsp;enhance the fisheries potential of these local ponds

A Determination of Interface Free Energies

We determine the interface free energy $F_{o.d.}$ between disordered and ordered phases in the q=10 and q=20 2-d Potts models using the results of multicanonical Monte Carlo simulations on $L^2$ lattices, and suitable finite volume estimators. Our results, when extrapolated to the infinite volume limit, agree to high precision with recent analytical calculations. At the transition point $\beta_t$ the probability distribution function of the energy exhibits two maxima. Their locations have $1/L^2$ corrections, in contradiction with claims of $1/L$ behavior made in the literature. Our data show a flat region inbetween the two maxima which characterizes two domain configurations.Comment: Submited to Nuclear Physics B (FS) Latex file, 24 pages, 11 PostScript figures.
