Epoxidation of methyl esters derived from Jatropha oil: An optimization study

The optimization of the epoxidation reaction of methyl esters obtained from Jatropha oil was appraised. Response surface methodology (RSM) based on a central composite rotatable design (CCRD) was employed for the experimental design. Four reaction variables namely hydrogen peroxide/ C=C mole ratio, formic acid/C=C mole ratio, reaction temperature and reaction time were evaluated. The optimum epoxidation conditions calculated by the quadratic model were 3.12 moles of hydrogen peroxide/C=C moles, 0.96 moles of formic acid/C=C moles, a reaction temperature of 70.0 °C and a reaction time of 277 minutes. A reaction optimized by the proposed process parameters provided a yield of 92.89 ± 1.29 wt. % with relatively improved reaction time. Hydrogen peroxide concentration and reaction temperature were found to be the most significant variables while reaction temperature and hydrogen peroxide showed strong interactions. The epoxidized methyl esters were analyzed using FT-IR, 1 H NMR and 13 C NMR techniques. This study suggested relatively higher molar ratio of formic acid required than was proposed in the literature.

Digestion and nitrogen utilization by sheep fed diets supplemented with processed broiler litter

In vivo digestion and metabolism trials were conducted with 10 wethers equipped with ruminal, abomasal, and ileal cannulae to evaluate digestion of ensiled broiler litter (EBL), deepstacked broiler litter (DBL), and composted broiler litter (CBL). Wethers were fed a low protein (6.3% CP) basal diet alone or supplemented to 10.3% CP with EBL, DBL, CBL or soybean meal (SBM). All diets were formulated to be isoenergetic (56% TDN, DM basis). Apparent digestibilities of DM, OM, and ADF were not affected (p<0.05) by diet, but digestibility of CP was improved (p<0.05) by N supplementation. Apparent digestibility of CP was lower (p<0.05) for diets supplemented with CBL and DBL than for diets supplemented with SBM and EBL. Ruminal NH3 concentration was 20 to 24 mg/dl at 2 h after feeding litter-supplemented diets compared with 13 mg/dl for SBM. Abomasal N, NH3 N, and nonammonia N flows were increased (p<0.05) by N supplementation, whereas microbial N flow was not influenced (p<0.05) by diet. Compared with SBM and EBL, undegraded dietary CP flow to the abomasum tended to be greater (p<0.1) when wethers were fed DBL and CBL- supplemented diets. Retention of N (g/d) also was greater (p<0.05) due to greater (p<0.05) N intake and lower (p<0.05) urinary N excretion when wethers were fed diets supplemented with litter (especially EBL) vs. SBM. Overall, characteristics of ruminal fermentation and digestion indicated that broiler litter N was utilized efficiently by wethers, but ensiling may be preferable to deepstacking or composting.

Cold tongue/Warm pool and ENSO dynamics in the Pliocene

Abstract. It has been suggested that a "permanent" El Nino climate state has existed in the warm Pliocene. One of the main pieces of evidence of such conditions is the small east-west sea surface temperature (SST) difference that is found in proxy temperature records of the equatorial Pacific. Using a coupled version of the Zebiak-Cane model of intermediate complexity for the tropical Pacific, we study the sensitivity of the time-mean Pacific background state and El Nino/Southern Oscillation (ENSO) variability to Pliocene climate changes. The parameters varied in this sensitivity study include changes in the trade wind strength due to a reduced equator-to-pole temperature gradient, higher global mean temperatures and an open Panama gateway. All these changes lead to a westward shift of the position of the cold tongue along the equator by up to 2000 km. This result is consistent with data from the PRISM3D Pliocene SST reconstruction. Our model further suggests that ENSO variability is present in the Pliocene climate with only slight changes as compared to today. A background climate that would resemble a "permanent" El Nino with weak to no east-west temperature difference along the equator is only found for very weak trade winds which seem unrealistic for the Pliocene climate.
The SME Co-operation Framework: a Multi-method Secondary Research Approach to SME Collaboration

This work presents the SME co-operation framework, a model created to analyse the field of SME collaboration and to understand how small businesses co- operate. The constructs of this study are based on previous research on interfirm co-operation, which permits to cross- validate results from different studies, combine their findings and to create the framework to obtain a global idea of SME co- operation. The SME cooperation framework combines in a unique model the three main dimensions involved in SME cooperation (strategic, management and social) with the internal and external factors influencing business collaboration. Using the developed framework, the author summarizes why SMEs should co-operate, the problems SMEs face adopting collaborative approaches and the factors influencing interfirm collaboration effectiveness. The findings of this work provide some important implications for managers concerned with adopting collaborative approaches. From a managerial perspective, it shows that co-operation between SMEs is a valid approach for improving their performance as long as the success factors are considered, which in turn, reduces the risk of alliance failure.
How Can We Improve the Balanced Scorecard?

Balanced Scorecard (BSC) is one of the most popular performance measurement tools of the past two decades. However, many current and potential adopters of the BSC are not convinced that the technique is able to present a comprehensive picture of organizations’ performance. This commentary paper is aiming to address some of the shortcomings of the BSC in practice and provide some suggestions for its improvement. The BSC links non-financial measures with financial measures in four areas of performance concerned with financials, internal process, customers and innovation and learning [1,2]. The literature on the BSC has noticeably highlighted its effectiveness and its usefulness as performance measurement systems for the businesses [3-13]. The overall assessment is that the BSC can contribute to organizations’ performance if fully implemented. It enables organizations to clarify their visions and strategies and translate them into actions. It provides feedback around both the internal business processes and external outcomes to (continuously) improve strategic performance and results. When fully deployed, the BSC transforms strategic planning from an academic exercise into the nerve centre of an enterprise [1,14,15]. Nonetheless, despite its suggested merits, research on the diffusion of the BSC indicates that its adoption rate is lower than those of other managerial tools such ABC [16,17]. So, it is unclear if the BSC suffer from any shortcoming/s that might have contributed to its slow adoption in the current ever-changing environment of the 21st century. To learn more about the issues related to the adoption and the implementation of BSC in practice, we have surveyed more 1000 practitioners in different studies in Australia, New Zealand and the UK over the past 10 years. In these studies, we have investigated the impact of a variety of contextual factors such as attributes of the BSC, characteristics of adopters, characteristics of society, etc. on the adoption of the BSC. We have also explored practitioners’ views on the shortcomings of the BSC. While we have found many contextual factors are influencing managers’ decisions regarding the adoption of the BSC in practice, according to our findings, ignoring the risks, environmental and sustainability factors as well as neglecting the concerns/rights of other relevant stakeholders (besides customers) are the key shortcomings of the BSC, which could undermine its diffusion in practice. Further studies are recommended to explore how we can develop a comprehensive BSC to incorporate additional parameters such as sustainability, risk and environment factors into four classic perspectives of the BSC to address its short comings.
The work engagement and job performance relationship: Exploring the mediating effect of trait emotional intelligence

THE WORK ENGAGEMENT AND JOB PERFORMANCE RELATIONSHIP: EXPLORING THE MEDIATING EFFECT OF TRAIT EMOTIONAL INTELLIGENCE By Lisa Jackson This cross-sectional study examined the mediating effect of affect-related traits on the relationship between work engagement and job performance. Specifically, a sample of 225 students from a large state university was used to examine the effect of trait emotional intelligence (EI) on work engagement and both in-role and extra-role performance. It was found that work engagement directly impacted both in-role and extra-role performance, indicating that engaged workers are more likely to perform well both on job-related tasks (in-role performance) and also on going above and beyond what was expected of them in their job role (extra-role performance). In addition, work engagement was predictive of trait EI, indicating that engaged workers were more likely to use affect-related traits in the workplace than those less engaged. Further, trait EI was predictive of both in-role and extra-role performance, suggesting that effectively managing one’s emotions, exhibiting strong social skills, demonstrating self-control, and displaying a general sense of well-being (i.e., trait EI) can lead to improved performance on the job. Lastly, work engagement and both in-role and extra-role performance were partially mediated by trait EI. This study provides new information about trait EI and its effect on job-related behaviors in an applied setting.
The influence of religious/spiritual exercises on well-being and quality of life in dermatological patients: A quasi-experimental study

Abstract Interventional studies in the recent past have shown that an individual’s religious-spiritual (R/S) well-being helps in coping with chronic disease. In this quasi-experimental study, we performed two different interventions in 24 patients with systemic sclerosis, lupus erythematosus, and melanoma. One group of patients performed R/S exercises or attended a disease-specific lecture, and were compared to another group of patients who underwent no intervention. The R/S exercises produced a significant increase in Hope Transcendent (0.001) with the Multidimensional Inventory of Religious/Spiritual Well-Being compared to the lecture. Quality of life (QoL) improved significantly, specifically for the Mental Component Score of the Medical Outcomes Study 36-Item Short Form Health Survey, after the R/S exercises (p = 0.033) as well as the lecture (p = 0.011). This pilot study provided interesting insights on the impact of spiritual exercises in regard to Hope Transcendent, which was uniquely associated with the intervention. The study provided empirical evidence of the importance of the intervention, which would be valuable for the management of specific diseases in the clinical setting. This dimension of spirituality may help to overcome anxiety and fear of the inevitability of death while enabling patients to cope with chronic disease.
Finite element thermal analysis of the fusion welding of a P92 steel pipe

Abstract. Fusion welding is common in steel pipeline construction in fossil-fuel power generation plants. Steel pipes in service carry steam at high temperature and pressure, undergoing creep during years of service; their integrity is critical for the safe operation of a plant. The high-grade martensitic P92 steel is suitable for plant pipes for its enhanced creep strength. P92 steel pipes are usually joined together with a similar weld metal. Martensitic pipes are sometimes joined to austenitic steel pipes using nickel based weld consumables. Welding involves severe thermal cycles, inducing residual stresses in the welded structure, which, without post weld heat treatment (PWHT), can be detrimental to the integrity of the pipes. Welding residual stresses can be numerically simulated by applying the finite element (FE) method in Abaqus. The simulation consists of a thermal analysis, determining the temperature history of the FE model, followed by a sequentially-coupled structural analysis, predicting residual stresses from the temperature history. In this paper, the FE thermal analysis of the arc welding of a typical P92 pipe is presented. The two parts of the P92 steel pipe are joined together using a dissimilar material, made of Inconel weld consumables, producing a multi-pass butt weld from 36 circumferential weld beads. Following the generation of the FE model, the FE mesh is controlled using Model Change in Abaqus to activate the weld elements for each bead at a time corresponding to weld deposition. The thermal analysis is simulated by applying a distributed heat flux to the model, the accuracy of which is judged by considering the fusion zones in both the parent pipe as well as the deposited weld metal. For realistic fusion zones, the heat flux must be prescribed in the deposited weld pass and also the adjacent pipe elements. The FE thermal results are validated by comparing experimental temperatures measured by five thermocouples on the pipe outside surface with the FE temperature history at corresponding nodal points.
Diel and depth profiles of DNA photodamage in bacterioplankton exposed to ambient solar ultraviolet radiation

Bacteria play a central role in the cycling of nutrients and energy flow to higher trophic levels, yet the effects of ultraviolet-B (UV-B) radiation upon bacterioplankton have been largely overlooked. Using a highly specific radloimmunoassay, measurements of solar-induced DNA photodamage (cyclobutane pyriinldine dimers) were taken in planktonic samples collected from the northern Gulf of Ilcxico. Diel patterns of dimer accumulation and repair were observed in both the bacterloplankton ~ 1 7 1 ' fraction ( 0.8 pm < 120 pm), although damacje induction was approximately twice as much in the bacterioplankton fraction. Depth profiles of Dii \ damage in the bacterioplankton size fraction during cdlnl and moderate seas demonstrated the infl~iencc ot mixlng on t h e distribution of W radiation effects. During calm seas, damage was greatest in surface waters, decreased with depth, and could be detected to 10 m. In moderate seas, however, no net accumulation of damage was observed, even at the surface. The results demonstrate that bacteria are more susceptible to UV-B damage and may wrve as a more sensitive indicator of UV stress than other microorganisms. Wave action and mixing strongly influence the effects of UV-B in surface waters, demonstl-ating that UV-B effects may not always be predictable from measures of UV radiat io~ attenuation.
On SU(3) Effective Models and Chiral Phase Transition

Sensitivity of Polyakov Nambu-Jona-Lasinio (PNJL) model and Polyakov linear sigma-model (PLSM) has been utilized in studying QCD phase-diagram. From quasi-particle model (QPM) a gluonic sector is integrated into LSM. The hadron resonance gas (HRG) model is used in calculating the thermal and dense dependence of quark-antiquark condensate. We review these four models with respect to their descriptions for the chiral phase transition. We analyze the chiral order parameter, normalized net-strange condensate, and chiral phase-diagram and compare the results with recent lattice calculations. We find that PLSM chiral boundary is located in upper band of the lattice QCD calculations and agree well with the freeze-out results deduced from various high-energy experiments and thermal models. Also, we find that the chiral temperature calculated from HRG is larger than that from PLSM. This is also larger than the freeze-out temperatures calculated in lattice QCD and deduced from experiments and thermal models. The corresponding temperature and chemical potential are very similar to that of PLSM. Although the results from PNJL and QLSM keep the same behavior, their chiral temperature is higher than that of PLSM and HRG. This might be interpreted due the very heavy quark masses implemented in both models.
Treatment of swine wastewater with subsurface-flow constructed wetlands in Yucatán, Mexico: Influence of plant species and contact time

This study evaluates the capability of horizontal subsurface-flow constructed wetlands (SSF CWs) for treating pretreated swine wastewater as a function of contact time (CT) and type of macrophyte under the local conditions of Yucatan, Mexico. Experiments were conducted from July 2004 to November 2005 on a swine-fattening farm. The study had three stages: first, macrophytes were located and collected; second, plants were acclimatised; and third, a pilot plant with 6 wetlands was set up, operated and evaluated. The effectiveness of the wetlands was intensively tested over 2 periods (April and November 2005). The results indicate that treatment efficiency significantly improved with increased CT for most of the analysed contaminants. The highest removal rates were recorded at a CT of 3 d and ranged between 64 and 78% for total suspended solids, 52 and 78% for COD, 57 and 74% for BOD5, 57 and 79% for total nitrogen, 63 and 75% for ammonium nitrogen, 70 and 81% for nitrate, 0 and 28% for total phosphorus and 3.3 and 4.2 log-units for total coliforms. Results also suggest that the macrophyte species used did not significantly differ on their contribution to overall treatment efficiency. However, vegetated beds slightly improved water quality when compared to unplanted systems. Horizontal SSF CWs are a suitable technology for treating swine wastewater under the local conditions of Yucatan. Contact time should be given special attention in the design of future full-scale facilities.
MODELLING CHANGES IN THE GLOBAL METHANE HYDRATE INVENTORY

We present results from a study designed to investigate how the global methane hydrate reservoir has changed through the last glacial-interglacial cycle. Bottom water conditions are derived from a series of long-integration snapshot-type HadCM3 GCM experiments that cover the last 120 kyr. We use this dataset to drive a 1D transient hydrate model. We first evaluate the model using sensitivity experiments against a number of hydrate bearing ODP/DSDP sites. We then explore potential initial and final steady-state inventories using Pliocene and modern boundary conditions and compare to previous studies. We then investigate how the potential volume of submarine hydrate has evolved from initial Pliocene conditions through a series of pseudo glacial cycle. We find that the potential volume increases from 7.3 × 10 6 km 3 during the Pliocene to between 7.95 and 8.10 × 10 6 km 3 during the last glacial cycle. Finally, we use our transient hydrate model, within a series of sensitivity studies, to investigate how the evolution of this potential volume is occupied by hydrate.
Presage Biology: Lessons from nature in weather forecasting

The method used by local and indigenous peoples for predicting rainfall and other weather conditions solely on the basis of bio-indicators – the phenology of plants and behavior of animals – is coined as a new term: Presage Biology. Some of these activities of floral and faunal diversity are described in their application to predict oncoming rain, based a literature review as well as personal observations of present author as well as other reference sources pertaining to India and different parts of the world.
Knowledge Management as a Strategic Tool to Foster Innovativeness of Smes

This study examines the relationship between knowledge management (KM) (in terms of external acquisition and internal sharing) and innovation behavior. The concept of absorptive capacity and assumptions from the dynamic capabilities view underlie the proposed framework and hypotheses. The framework is empirically tested using a random sample of 649 Dutch small to medium sized enterprises (SMEs). Our empricial results indicate that external acquisition practices play a key role in fostering SMEs’ innovativeness while internal sharing practices do not appear to have a significant influence. External acquisition activity enhances a firm’s awareness of available knowledge opportunities. Firms which actively acquire external knowledge (regardless of the type of knowledge) may build a greater competitive dynamic capability to sense and seize business opportunities which in turn may lead to new or improved products or processes. We suggest that owners/entrepreneurs of SMEs and their firms will benefit in the long term if they strategically manage knowledge, especially using external acquisition practices.
