The aim of this research is to know the thoughts of Bali bureaucrats and intellectuals of Bali on tourism communication in maintaining the sustainability of Tri Hita Karana (THK) insight. The method used is postpositivism with the applied theory of reality social construction of Berger and Luckmann. The result of the research shows that the thought of Bali bureaucrats and intellectuals toward the phenomenon of Balinese tourism industry, both acknowledge that THK is an element that must be preserved. The reality construction of Balinese bureaucrats and intellectuals towards the phenomenon of Balinese tourism industry is different. Bureaucrats see that THK is not experiencing distortive threats, while intellectuals view that THK is being in a really distorted position. THK by bureaucrats is constructed as a potential commodity, whereas THK by intellectuals is constructed as an identity (cultural) struggle. According to bureaucrats, communicators are tradition leaders, communicants are tourists and the message content is the universal language of THK as harmonization of all circles. Meanwhile, according to intellectuals, communicator is Bali government, communicants are investor and the message is mass tourism threat.

The present study was conducted in Jammu district to assess the existing small ruminants rearing practices followed by the Bakarwal tribe. The data was collected from 120 Bakarwal respondents belonging to Marh, Satwari, Bhalwal and Dansal blocks of Jammu district with the help of structured interview schedule containing selected dependent and independent variables, through personal interview technique. The findings revealed that majority of the respondents were middle aged with poor education. The respondents had medium herd size, marginal land holdings and medium source of information. They were rich in cultural attributes and had good relationship with other communities. However, they belonged to medium income group and the property is inherited to youngest son in the family. Overall existing practices level of the respondents regarding sheep and goat rearing practices was medium with the existing practice's value of 58.72% and mean existing practices score value of 45.68±0.43. Respondents were following low existing practice in breeding (47.64%) as compared to the existing practice of feeding (68%), management (57.63%) and health care (55.67%). Majority (71.1%) of the respondents were following medium level of existing practices (57.90%), whereas, (10.0%) of the respondents had low existing practices (47.44%) and only (8.3%) of the respondents had high existing practices (67.24%). Insignificant positive association of independent variables, age (r=0.052), herd size(r=0.078), cultural attributes and relationship with other community (0.051), total annual income (r=0.178) and indigenous knowledge (r=0.152) was observed with existing practices. On the other hand source of information (r=-0.424**) was negatively and significantly associated with existing practices. Insignificant negative association of education (r=-0.080), landholding (r=-0.150), ownership pattern (r=-0.019) and marketing pattern (r=-0.110) was observed with existing practices of level sheep and goat rearing practices.

The pull out of steel bars bonded-in in structural wood pieces present highly satisfactory performance concerning esthetics, strength and connection stiffness, nevertheless, great concerns arise relating to the bonding quality control, making some authors suggest that the bonding operation must be done in a factory environment with the adequate quality control and by specialized people. Several studies have been published analyzing methods of production control or the effect of common contaminators, present in the bonding area which might affect the global capacity of the connection. In this work, anchorage strength was evaluated under the effects of four superficial treatments on the anchorage area of steel bars and increasing and decreasing moisture variations after bonding. The adhesive used was the epoxy resin Sikadur32 Fluid and the steel bars were perpendicularly fixed to the wood fibers, obtained through a random sample of a lot of sawed Corymbia citriodora wood. In 98.70% of rupture, specimen occurred due to loss of resin adhesion on the bar surface, due to chemical and mechanical loss adhesion.

Over the past decades, various methods have been proposed to evaluate drilling depth and complexity because of the large number of factors and events that affect drilling performance, which makes it difficult to construct predictive models. Quantifying drilling oil well depth and complexity is challenging due to restrictions on data collection and availability, constraints associated with modeling or combinations of these factors. Drill rates are often not documented and constrained by factors that the driller does not control. In large investments, the requirements to drill for oil and gas are made primary by oil companies. Many specialized talents are required to drill an oil well safely and economically. Estimation of the depth of oil well is one of the major concerns of oil companies today. The aim of this paper is to study and analyze the associated depth drilling parameters, and to run a comparative analysis of simulated events and regression model software values by adopting mathematical model of multiple regression that transform into programming technique for predicting total depth of drilling oil well. Visual Basic Net programming language (front-end) and Microsoft Access Database relational database management (back-end) were used in the research work for the experimental study. The implemented software has a performance accuracy of 93.94%. The data series explained that higher the drill depth more is the total cost.

In Brazil, don’t have a standard code which rules the shear connector tests for mixed wood-concrete structures. Due to the excellent connector diversification, regarding shape, stiffness, limit strength and the placement in the structural member; and variables as: spaces between connectors, spaces between connectors and the member ends of wood or concrete, dimension variation and mechanical properties of the materials involved, besides the rate and reinforced grid disposition in the concrete members, several normative documents suggest that wood-concrete specimens represent the real connection behavior. In this work, were used a push-out type specimen to characterize the connectors formed by bonded-in steel bars in “X” type behaviour, with a 45º between steel bars and wood grain. In this work, were used: Corymbia citriodora wood specie, without surface treatment; Threaded surface steel bars (CA-50 steel); and reinforced concrete of medium strength. Steel bars were bonded in the wood with epoxy resin Sikadur32 fluid and anchorage in the concrete by adherence. In each steel bar, in the axial direction and in the shear plan surface, two electric extensometers were fixed in opposed points. Results present the steel bar anchorage behaviour, force distributions in the steel bars, as well as the rupture model and mechanism and the procedures to obtain the connection sliding modulus and limit strength.

It is essential to have full knowledge of wood properties, such as strength and stiffness, for the preparation of reliable structural designs. The Brazilian Code ABNT NBR 7190 (1997) establishes that the modulus of elasticity in compression perpendicular to grain (Ec90) can be obtained in a simplified way, in the absence of experimental determination, by means of a correlation with the modulus of elasticity in the direction parallel to grain (Ec0 = 20 Ec90). In order to verify the adequacy of this expression, the results obtained for five species of wood, covering the strength classes assumed by the mentioned Code were analyzed: Cambará Rosa (Erisma sp.), C20; Cedro Amazonense (Cedrella sp.), C30; Cupiúba (Goupia glabra), C40; Itaúba (Mezilaurus itauba), C50; Roxinho (Peltogyne sp.), C60. For each species, from the tests prescribed by ABNT NBR 7190, the elastic moduli were obtained in the directions parallel and normal to grain. In the evaluation of the precision of the proposed estimation, the least squares method was used to determine the coefficient α of the investigated relation. For the data set involving the five species studied, the coefficient resulted in α = 20.64. This value is compatible with the correlation proposed by the Brazilian standard, evidencing its reliability.

The need for cashless economy in the banking sector has introduced electronic banking popularly called the e-banking system. This system helps to limit the volume of physical cash in circulations. It encourages the use of electronic (computer platform) to perform payment through bank transfer. This kind of system has been seen to be very useful in moving any economy from cash-based economy to a cashless economy with numerous advantages. However, the current security features of this platform that enable the online payment through bank transfer are very weak. This is so because, during the use of the current online payment platform, the user is expected to provide some security digit codes usually four digit number as personal identification number (PIN) used during registration in the platform to authenticate the money transfer. Since people can easily misplace their PIN, there is need to use a more robust method in securing this platform. Hence, this paper has presented the use of more than one human physiological feature in securing this platform. The primary research objective of this paper is to design a better multimodal biometric architecture suitable for securing online payment platform.
