Preparation of Biofuel Using Acetylatation of Jojoba Fatty Alcohols and Assessment as a Blend Component in Ultralow Sulfur Diesel Fuel

The majority of biodiesel fuels are produced from vegetable oils or animal fats by transesterification of oil with alcohol in the presence of a catalyst. In this study, a new class of biofuel is explored by acetylation of fatty alcohols from Jojoba oil. Jojobyl methyl acetate (JMA) was produced using direct acetylation of purified jojobyl alcohol obtained during preparation of Jojobyl methyl esters (JME). Important fuel properties of JMA, such as kinematic viscosity, cloud point (CP), pour point (PP), cold filter plugging point (CFPP), acid value, oxidative stability, gross heat of combustion, and lubricity were evaluated using standard methods. A comparison was made with previously reported JME and relevant biodiesel fuel standards, such as ASTM D6751 and EN 14214. The CP, CFPP, and PP values of JMA were 2, −10, and −16 °C, respectively. These results were comparable to JME with the exception of a higher CP in the case of JMA. The kinematic viscosity (40 °C) of JMA was 7.64 mm2/s, which was higher than t.
SPACE VECTOR PWM TECHNIQUE FOR THREE- TO SEVEN-PHASE AC-TO-AC POWER CONVERTERS: ANALYSIS AND EXPERIMENTAL VERIFICATIONS

This paper presents Pulse Width Modulation (PWM) control technique for three to seven-phase acto-ac power converters. These proposed PWM techniques are based on Indirect Space Vector Modulation (ISVM), which model the converter as two independent stages perform rectification and inversion stages. Two schemes of ISVM are proposed. The first scheme maximizes the voltage transfer ratio (VTR) of the converter but it produces unwanted low order harmonics. The second scheme generates sinusoidal output voltage waveforms; the cost is a reduction in the VTR of this configuration in linear mode. The viability of the proposed technique is proved using experimental results.

Abstract Alkaptonuria (AKU) is a genetic disorder inherited in accordance with Mendel first law. Mutations in the HGA gene result in the AKU disorder. Three major features of this disorder: arthritis, ochronosis, and the presence of Homogentisic Acid (HGA) in the urine. The author searched the PubMed Databases at National Center for Biotechnology Information (NCBI) for articles on AKU published between 2014 and 2019. All articles were open access and in English. In this systematic review, the author included one’s own references and other relevant publications. Search results showed that detection tools for people with AKU can include x-rays and genetic tests. No adequate treatment is available for AKU at present. However, counselors of genetic counseling may help patients with AKU and give counseling to them and their families. Candidate drugs of AKU are nitisinone and genetic manipulation techniques. Research results on the use of nitisinone on AKU have shown remarkable improvements. In the future, genetic manipulation techniques may be beneficial for treating AKU. These techniques are such as modified CRISPR/Cas9 (FokI-dCas9), End-Joining Homology Techniques (EJHTs) and induced Pluripotent Stem Cells (iPSCs).
Presenting and Evaluating Scaled Extreme Programming Process Model

Extreme programming (XP) is one of the widely used software process model for the development of small scale projects from agile family. XP is widely accepted by software industry due to various features it provides such as: handling frequent changing requirements, customer satisfaction, rapid feedback, iterative structure, team collaboration, and small releases. On the other hand, XP also holds some drawbacks, including: less documentation, less focus on design, and poor architecture. Due to all of these limitations, XP is only suitable for small scale projects and doesn’t work well for medium and large scale projects. To resolve this issue many researchers have proposed its customized versions, particularly for medium and large scale projects. The real issue arises when XP is selected for the development of small scale and low risk project but gradually due to requirement change, the scope of the project changes from small scale to medium or large scale project. At that stage its structure and practices which works well for small project cannot handle the extended scope. To resolve this issue, this paper contributes by proposing a scaled version of XP process model called SXP. The proposed model can effectively handle such situation and can be used for small as well as for medium and large scale project with same efficiency. Furthermore, this paper also evaluates the proposed model empirically in order to reflect its effectiveness and efficiency. A small scale client oriented project is developed by using proposed SXP and empirical results are collected. For an effective evaluation, the collected results are compared with a published case study of XP process model. It is reflected by detailed empirical analysis that the proposed SXP performed well as compared to traditional XP.
Detection of time shift failures in (max, +)-linear systems with time intervals for assembly line

In this paper, we address the problem of failure detection in assembly lines modeled as Timed Event Graphs (TEG). The proposed method represents TEGs as (max,+)-linear systems with time intervals and aims at detecting time shift failures in the underlying assembly lines. To do so, we propose the definition of a set of indicators relying on the residuation theory on (max,+) linear systems that handle certain and uncertain observable outputs
Probiotic and anticancer activity of fermented rice water

Objective: Cancer is a major health concern and it remains one of the main causes of death among human being. Free radicals are known to be the influencing factors for many diseases. The excessive free radical production and low antioxidant defense is caused by oxidative stress, which is harmful and also strongly associated with cancer development. Consuming overnight fermented rice water is a very old practice followed in Tamil Nadu, India. The present study was attempted to investigate the health benefits of Fermented rice water. Methods: The cooked fermented white rice water (0 hour, 24 hours) samples were used in the study. Isolation, identification of organism was done by morphological tests like gram staining, motility, endospore staining and catalase. The antibacterial activities were performed using agar disc diffusion method against Escherichia coli, Salmonella typhi, Staphylococcus aureus, Klebsiella punemoniae. Phenolic compounds were separated using chloroform solvent from fermented white rice water. The separated fractions were used for further studies, and their total phenolic content was determined by qualitative and quantitative methods. The compounds present in the (0 and 24 hours) samples were further analyzed using GC-MS assay. Results: 0 hour fermented cooked rice water contained ten compounds whereas 24 hours fermented rice water contained twenty three compounds. The fermented cooked rice water was capable of inhibiting proliferation of hepato cellular carcinoma cells with IC50 of 125 μg/ml inhibiting 49.41% of liver cancer cells. Conclusion: The study reports the fermented cooked rice water as natural therapeutic agents with antimicrobial, antioxidant and anticancer activities. Daily intake of this fermented rice water in our diet is beneficial in many ways and would be a natural source of phenolics for common man in developing countries.
L-Arginine Protective Effect on Systemic Blood Pressure and Placental Expression of Endoglin, Transforming Growth Factor-β1 in the Preeclampsia Mice Model

Preeclampsia is a significant contributor to maternal morbidity and mortality, especially in developing countries. In general, 10% of pregnancies have complications of preeclampsia (1). Wardhana’s study from one of the tertiary services in eastern Indonesia demonstrated an up to twice prevalence that of 21% (1106 cases) for two years. The high maternal mortality rate in Indonesia (359 in 2012) shows that this condition is still a big problem in developing countries (2). One of the characteristics of preeclampsia is the occurrence of global vasoconstriction, which shows the possibility of a decrease in NO endothelial production. Studies have indicated that a disorder of transforming growth factor beta 1 (TGF-β1) caused by its binding to sEng can interfere with the activation of nitric oxide synthase (NOS) to produce nitric oxide (NO), along with the vessel vasodilation and angiogenesis leading to vasoconstriction and endothelial dysfunction as the characteristics of preeclampsia (3). L-arginine, as a NO precursor, is a semi-essential amino acid in which production is not enough when the NO requirement increases as in some conditions of pregnancy with specific pathologies. The concentration of L-arginine is known to decrease significantly in preeclampsia compared to normal pregnant women who show the potential for NO production disturbances (4). L-arginine has the role of producing NO as a vasodilator to increase placental blood flow so that it can improve the shallow condition of placental implantation, angiogenesis, and vasoconstriction. However, this hypothesis still requires further research to ensure a better pathogenesis pathway. It is fascinating to know the role of L-arginine in the systemic clinical parameters of preeclampsia such as blood pressure and its local pathogenic pathways in the placenta through the examination of Eng and TGF-β1.

Phenolic compounds are classified as hazardous materials that polluted groundwater and surface water resources. The present work have been applied photoFenton process for removal of phenolic wastewater, also it concerned with the optimization of the operating parameters that affect the photo-Fenton process. Using the Response Surface Methodology (RSM) to explore the influence of operational variables such as hydrogen peroxide and the iron ion weight ratio, pH, contact time on the removal of phenol. The predicted removal obtained from the model are in a good agreement within the results of experiments with a high correlation regression of 0.993. The expected maximum removal was to be 80.12 % while the experimental results was 81%. The study estimated the influence of [Fe 2+ /H2O2] weigh ratio from 20-60, contact time from 30-90 min and pH range from 2 to 8, at solution containing of 100ppm phenol. A Box–Behnken design was applied to optimize the operating parameters. The graphical response surface and contour plots were employed to determine the optimum conditions. The results showed that the optimized value of the [H2O2/ Fe 2+ ] = 40.4, contact time= 55 min, and pH=5.2 giving a reduction efficiency of 80.12%.
Working Papers 2020-07 A decade of nudging : What have we learned ?

In the past decade, Nudging as a method to influence behavior has received increased attention both among academics and more generally. Nudges are often low-cost interventions but may nevertheless be surprisingly effective. However, as the research field has matured, it has also become clear that nudges are not always as effective as originally thought. In this paper, I give a selected overview of recent nudging interventions and discuss what we have learned from the past decade of using nudging to affect behavior.
Perception of the hedonic value of residences in the neighborhood of Three Green Urban Parks

The objective of this article was to examine how users and residents of three urban parks in Campo Grande, MS, Brazil, perceive their existence, degree of satisfaction and attitudes in preserving them. A quantitative approach was employed in 412 users of the three Parks. Information on its sociodemographic characteristics, satisfaction with the park and environmental preservation attitude was collected, employing a seven-point Likert scale. The data collected revealed that the general satisfaction with the park contributes to the hedonic perception of the increase in the property value. From the factor variance analysis, overall satisfaction, preservationist attitude and park location showed significant relationships, such as interactions in the increase in the property value. It is noteworthy that there are differences in the perception of the satisfaction of residents close to the three parks. This article presents some interesting relationships under the aspects of theoretical implication, such as the contribution to studies on the City Parks and their relations with users and residents around them.

Diaryldistyrylpyrazines: Solvatochromic and Acidochromic Fluorophores

Diaryldimethylpyrazines are the starting materials for the synthesis of C2-symmetric donor- or acceptor-substituted distyrylpyrazines. The optical properties of these cruciform-shaped dyes are dominated by the distyrylpyrazine units; the photophysics is controlled by the styryl substitution, the diaryl substituents on the central pyrazine only having a small effect. Protonation occurs on the pyrazine and/or lateral amines or azines, thereby altering the absorption and emission properties. Hypso- and bathochromism as well as fluorescence quenching depend on the nature of the terminal substituent. This, and a significant positive solvatochromism of the fluorescence, allow optical sensing of the pH and polarity of the environment.

Examining effects of individual differences in empathy on behavioural and neural processing of music

The pervasive nature of music in human lives, from day to day activities to large scale concerts makes it an important part of human social interactions. From an evolutionary perspective, it has been argued that music has the capacity to evoke shared responses within groups, thereby allowing it to act as a form of social glue increasing group cohesion. One proposed mechanism for these shared responses is empathy. Over the last decade, a great deal of research has sought to identify the behavioural mechanisms underlying the affective capacity that music affords. These studies have put forth various theories that suggest an integral role played by empathy in inducing emotions while listening to music. In this thesis, we try to expand our understanding of empathy in the context of music processing from both behavioural and neural fronts. Through an extensive literature review, we find that previous studies on empathy have sought to examine it in terms of two distinct but related subsystems: The cognitive subsystem, which is concerned with top-down aspects of empathy such as motor-mimicry and the affective subsystem, which primarily deals with bottom-up aspects related to affect processing such as emotional contagion. In the first study, we looked at behavioural differences in self-reported continuous ratings of ”feeling moved” while participants listened to continuous pieces of music. Using a data-driven approach to cluster the ratings, we found significant differences in ”feeling moved” to both sad and joyful music modulated by participants’ affective empathy. Our results provided empirical support to the aforementioned Cognitive vs. Affective framework of empathy from a behavioural standpoint. In the second study, we sought to extend our earlier work by examining how empathy modulated brain responses while listening to music using Functional Magnetic Resonance Imaging (fMRI). Prior to the current study, neuroimaging studies investigating the role of empathy in music processing have been scarce and did not examine functional connectivity in the brain. Our study overcomes this limitation by examining both global and localised processing of music modulated by empathy through graph-theory based methods. Overall, we found differences in global and local connectivity patterns in music processing modulated by participants’ trait empathy. Participants scoring higher on cognitive empathy tended to recruit mechanisms related to motor mimicry, whereas those scoring higher on affective empathy were found to recruit regions related to auditory affect processing. Both of our studies corroborate previous research in the field in addition to providing novel findings and as a result further supporting the existence of two subsystems in Cognitive vs. Affective framework of understanding empathy.
