Comparison on Accuracy of Logistic, Gompertz and Von Bertalanffy Models in Predicting Growth of New Born Calf Until First Mating of Holstein Friesian Heifers

The body weight records of 1221 heifers were used in this study collected from PT Taurus DairyFarm Sukabumi from year 2001 until 2011. The records that could be used for analysis were 373 out of1221 heifers, having completed data from birth to first mating period. Three different models i.e,Logistic, Gompertz, and von Bertalanffy were performed to analyze the growth rate of heifers. Theresults showed that the three models had different accuracy and heavily depend on age, environment andduration of recording. The body weights of sexual maturity and on certain ages were affected by theduration of recording. The Gompertz model was performed as the simpliest model in form ofcalculation. On the other hand, the Logistic was more difficult to calculate. All models indicated highaccuracy with the determination coefficient (R2) more than 90%. Based on the comparison, theGompertz and Logistic model are recommended for predicting the growth rate of heifers from birth tosexual maturity

Studies of monomer impregnation and polymerised in situ in wood using dynamic mechanical thermal analyser.

Ten tropical hardwoods are impregnated with methyl methacrylate and polymerised in‐situ by use of catalysts and heat techniques. Treatability of the wood, as determined from the fractional volumetric retentions of monomers that are a fraction of voids filled by the impregnant, showed that the mean retention range from 15·03% (Acacia Mangium) to 56·59% (Cratoxylum Arborescens). The penetration of the monomer evaluated using ultrasonic waves showed that the treated wood had higher velocities which indicated significant increase in density. The present paper deals with the viscoelastic relaxation of polymerised treated wood. The efficiency of the monomer as a plasticiser is studied through the temperature dependence of the storage modulus (E′) and loss tangent (tan δ) of treated and untreated wood by dynamic mechanical thermal analysis (DMTA) over a temperature in the range from −100 to 200°C. The storage modulus E′ decreased with temperature and as the maximum mechanical damping developed, the glass transition temperature (T g) of the plasticised wood decreased with the plasticiser content

Developmental research of sustainable technologies to minimise problematic road embankment settlements

Challenging, problematic and non-uniform ground conditions are a night mare to geotechnical engineers tasked with the design and construction of buildings and transport infrastructure. These often suffer undesirable structural settlements. Designing within the current understanding of geotechnics; settlement in peat and organic soils need to be recognised to include the known “primary and secondary consolidation characteristics” and the lesser known “tertiary consolidation phase”. These eventually contribute cumulatively to the consequential uneven and hazardous “bumpy road” surfaces. Undulating flexible road pavements result primarily from the transference of the heavy self-weight of the embankment fill to yielding and non-uniform subgrade. The adoption of conventional design/repair methods such as pile, vertical drain, soil replacement and soil stabilisation are expensive and inappropriate in very soft ground conditions. These then lead to unjustifiably high and repetitive maintenance costs. There being no one quick fix solution for all; pragmatic research must necessarily identify the best/progressively improved practical and sustainable solution. A viable solution is to develop criteria and explore the concept of a “masonry arch bridge structure/lintel-column structure” and adopting sustainable materials through pragmatic searching for appropriate recyclable waste materials. This will lead to the basis for a sustainable, innovative, strong, stiff, permeable composite mat structure that can be used on soft and/or yielding ground conditions. Conceptual lightweight fill technology including the popularly used expanded polystyrene (EPS) and the innovative composite mats recently being developed by the research team are outlined

The design of dust barriers to reduce collector mirror soiling in CSP plants

In this work we investigate, design, and evaluate a number of dust barrier designs that would be appropriate to reduce soiling of glass mirror solar collectors in the solar field of an existing CSP plant. The principal objective was to reduce the amount of soiling (and hence the amount of cleaning water consumed) by 50% in comparison with current cleaning procedures (considering particles of size >25 µm). “Fluent” CFD software was used to model of a range of potential dust barrier shapes, sizes, and porosities. Airflows and wind loadings were analyzed in this way. A number of potential designs were then taken forward for experimental validation. Initial validation involved wind tunnel evaluation of a small number of potential designs, using a new wind tunnel specifically designed and built for this project. Larger-scale outdoor validation was carried out both at Cranfield University in the UK and at CIEMAT-PSA (Plataforma Solar de Almeria) in Spain. Initial results were independent of location and barrier shape and showed that the percentage of particles that were stopped completely or travelled less than 1m beyond the barrier was in the range 45.8 ± 5%

Size reduction of selected spices using knife mill: Experimental investigation and model fitting.

The process of size reduction is significant in numerous industries to improve performance and meet specification. This research is undertaken to study the size reduction of three spices, namely cinnamon, coriander and star anise as influenced by loading weight and grinding time. Grinding was conducted in a knife mill. The dependent variables used for assessing performance were grinding efficiency, size reduction ratio and grinding rate. Simple experimental model was built using Microsoft Excel for showing the relationship between cumulative size reduction function (Bij) and selectivity function (Si) with the physical properties like density, moisture content and hardness of spices used. It was observed that there was a gradual decrease in size of spices up to grinding of 1 min and then became constant. Among the three spices, cinnamon achieved the highest size reduction as evaluated by efficiency, size reduction rate and size reduction ratio. The optimum loading weight for grinding was found 30 g irrespective of the type of spices. The data of cumulative size reduction function, selectivity and particle size fitted to second-order polynomial equation with the highest goodness of fit. This study indicated that the size reduction/grinding using knife mill was greatly influenced by physical properties of spices among the factors studied

Managing Chronic Pain in an Opioid Crisis: What is the Role of Shared Decision-Making?

Shared decision-making (SDM) is a widely-advocated practice that has been linked to improved patient adherence, satisfaction, and clinical outcomes. SDM is a process in which patients and providers share information, express opinions, and build consensus toward a treatment decision. Chronic pain and its treatment present unique challenges for SDM, especially in the current environment in which opioids are viewed as harmful and a national opioid crisis has been declared. The purpose of this qualitative study is to understand treatment decision-making with patients taking opioids for chronic pain. Ninety-five clinic visits and 31 interviews with patients and primary care providers (PCPs) were analyzed using the constant comparison method. Results revealed that 1) PCPs desire patient participation in treatment decisions, but with caveats where opioids are concerned; 2) Disagreements about opioids, including perceptions of lack of listening, presented challenges to SDM; and 3) PCPs described engaging in persuasion or negotiation to convince patients to try alternatives to opioids, or appeasing patients requesting opioids with very small amounts in an effort to maintain the patient-provider relationship. Results are discussed through the lens of Charles, Gafni, and Whelan’s SDM model, and implications of the role of the patient-provider relationship in SDM and chronic pain treatment are discussed
