Abstract: the objective of this work was to investigate the effects of shading on the growth and development of the medicinal plant ocimum selloi after 90 days. seedlings were maintained under three different light treatments, namely, full sunlight vs coloured shade treatments provided by red and blue chromatinet? 50% coloured netting. after 90 days of cultivation, height, stem diameter, petiole length, total leaf area (tla), specific leaf area (sla), leaf area ratio (lar) and leaf weight ratio (lwr) of each plant hare measured. microscopic examination of leaf sections were conducted in order to determine the leaf blade thicknesses, together with the size and density of the stomata, the number and area of chloroplasts, and chloroplast starch grains present in the palisade parenchyma cells. although coloured shade-grown plants were taller in comparison with those grown in full sunlight, total dry biomass together with root, stem and leaf tissue biomasses were lower. plants exhibited phenotypic plasticity, as demonstrated by the different tla, sla, lar and lwr values that were recorded under the various light treatments. stomatal density and leaf thickness was increased in plants maintained in full sunlight owing to the expansion of the abaxial epidermis and the spongy parenchyma. chloroplasts were more numerous and larger in plants grown under shading, whilst the accumulation of chloroplastic starch grains was greater in plants grown under red shading or in full sunlight.

Abstract: This study aimed to evaluate the effect of shading on the production of essential oil and biomass in Lippia citriodora (Lam.) – known as cidr o – in the north of Minas Gerais, Brazil. The experimental design was completely randomized, with four treatments and five repetitions. The treatments consisted of four levels of photosynthetically-active radiation (PAR) using “Sombrite” black shade netting of 25, 50, 70% of light and full sunlight as the control. The variables root dryness, shoot dryness, number of flowers, total dry weight, root/shoot ratio, and production and content of essential oil were analyzed. Statistically significant differences were observed for the root and shoot dry masses and total dry mass, number of flowers, total dry weight, root/shoot ratio, oil production and trichome number, but not for the oil content. The results showed that at full sunlight the biomass production and trichome number of cidr o were altered, but that the content of essential oil was unaffected.

Jurnal Teknik Industri , 2010,
Abstract: Indonesia has in the past often been struck by natural disasters. After these disasters, the disaster relief operations turned out to be ineffective in most cases. This study focuses on the main problems in disaster relief operations in Indonesia and tries to deliver a general model to deal with those. Literature studies showed that the main problem occurred in the field of organization, communication and logistical processes. Literature studies on relief operations in other countries showed that cooperation with private parties can be effective in these operations. The result of this study is a model which handles with the main problems and has the potential to create effective disaster relief operations.

Abstract: Knotless polyethylene(PE) netting has been widely used in aquaculture cages and fishing gears, especially in Japan. In this study, the hydrodynamic coefficient of six knotless PE netting panels with different solidity ratios were assessed in a flume tank under various attack angles of netting from 0?(parallel to flow) to 90?(perpendicular to flow) and current speeds from 40 cm s~(-1) to 130 cm s~(-1). It was found that the drag coefficient was related to Reynolds number, solidity ratio and attack angle of netting. The solidity ratio was positively related with drag coefficient for netting panel perpendicular to flow, whereas when setting the netting panel parallel to the flow the opposite result was obtained. For netting panels placed at an angle to the flow, the lift coefficient reached the maximum at an attack angle of 50? and then decreased as the attack angle further increased. The solidity ratio had a dual influence on drag coefficient of inclined netting panels. Compared to result in the literature, the normal drag coefficient of knotless PE netting measured in this study is larger than that of nylon netting or Dyneema netting

Abstract: A quick and simple approach for reactor—emergency relief system design—for runaway chemical reactions is presented. A cookbook for system sizing with all main characteristic dimensions and parameters is shown on one realistic example from process industry. System design was done based on existing theories, standards, and correlations obtained from the literature, which were implemented for presented case. A simple and effective method for emergency relief system is shown, which may serve as an example for similar systems design. Obtained results may contribute to better understanding of blow down system frequently used in industrial plants, for increasing safety, decreasing explosion damage, and alleviating the ecological problems together with environmental pollution in case of industrial accidents. 1. Introduction In process industry, raw materials are converted into various commercial products using different techniques. One frequently used method is their conversion by exothermic chemical reactions which can lead to a reactor thermal runaway if the heat generation rate exceeds the heat removal rate during process [1]. Pressure build-up during the runaway is caused by an increasing vapor pressure of liquid components and by the production of noncondensable gases. Apart from the loss of reactor inventory due to an uncontrolled conversion process, a runaway reaction may lead to severely damaged equipment or even a physical explosion if pressure build-up inside the reactor exceeds the design pressure. The emergency relief system is composed of vent area, vent rupture membrane, safety relief valve, vent pipes, blow down tank, horizontal condenser, scrubber with absorber and vertical condenser, outflow chimney, corresponding pumps, fan, pipes, fitting, and supply system with electricity, cooling water, and neutralization medium. In case of reaction runaway, the vent rupture disc opens and the reactor mixture blows out into the vent pipes and flows into blow down tank. Due to short residence time of reactor mixture in the blow down tank, the volume changes and the pressure decreases at isothermal conditions, which results in the condensation of reaction mixtures. Remained two phases flow instantaneously blows into horizontal condenser, where it cools down, condensates, and flows into absorber with vertical condenser, where it is neutralized [2–4]. In present study, a detailed design of emergency relief system is shown based on Design Method for Emergency Relief Systems (DIERSs). It incorporates the state-of-the-art knowledge obtained from mechanical,

Quantitative Biology , 2011,
Abstract: This paper reports on a simulated evolution project, which had the goal of simulating the refractive components of the PM eye of Australian netting spider diopis subrufus on a desktop computer. The model for the simulation is the anatomy of the eye described by Blest and Land [Ble & Lan 1977]. The evolution simulation was able to produce hundreds of eyes with equivalent optical qualities to the measured eyes for the phenotype of the netting spider. These artificially evolved eyes began to occur in the computer simulation between 8X106 and 35X106 cycles after Demonstration of Darwinian Theory of Evolution; arXiv 1006.0480 simulated the evolution for the ctenid spider PM eye, cupiennius sale. This paper follows the previous paper, but the netting spider eye is more complex than the ctenid PM eye so the simulated evolution equations are more complex.

Abstract: This paper studied the interregional joint allocation and transportation problem of relief materials for major unexpected public emergencies. To enhance the efficiency of large-scale interregional joint allocation and transportation of relief materials, developed a location-allocation model for transshipment nodes of relief materials. And also proposed a matrix-based genetic algorithm to solve the model. In the algorithm design process, in order to solve the defect of poor search ability and bad optimal result precision of the simple genetic algorithm, considered the cost matrix of the optimization-oriented benchmarking information to guide each individual to the fine local search space. Finally, the validity of the model and algorithm is demonstrated by a numerical example.

Abstract: Background and Objectives: Previous randomized trials of the analgesic effects of sucrose, glucose, and a pacifier in term neonates have shown that the pacifier resulted in lower pain scores than glucose or sucrose, but the pacifier with and without sucrose did not differ. The current study was designed to assess the analgesic effect of pharmacologic (sucrose, water) and a non-pharmacologic measures (pacifier) in preterm infants and to find whether there is any synergism between these intervention in relieving pain during painful procedures. Patients and Methods: In this double-blind, randomized, controlled study, 36 preterm infants (mean 31 weeks gestational age, range 27 to 36 weeks) were randomly allocated to six different regimens (0.5 mL sterile water with pacifier, 0.5 mL sterile water without pacifier, 0.5 mL sucrose 24% with pacifier, 0.5 mL sucrose 24% without pacifier, pacifier alone and control group) during a stay in intensive care of up to 15 days. Pain scores were measured with the Premature Infant Pain Profile (PIPP), a validated behavioral acute pain scale. Results: Of all the regimens, the lowest pain scores occurred with the use of 24% sucrose solution combined with pacifier. The mean pain score for the combination of sucrose with pacifier was 0.7 as compared to 1.4 for the sterile water with pacifier group (P< .05). Conclusion: The synergistic effect of the combination of sucrose and non-nutritive sucking was clinically effective and safe in relieving the pain of simple procedures such as venipuncture or heel stick in preterm and term infants, but further research is needed on these interventions alone and in combination with other behav--ioral interventions in neonates.
