Meta study on the optimisation of thermoacoustic cooling systems for efficiency and cooling load

The emerging field of thermoacoustic cooling systems (TACS) has been explored in recent years, combining the disciplines of acoustics and thermodynamics to provide an alternative to mainstream cooling technologies. This hybridised system allows a system of travelling or standing waves to absorb and release thermal energy at different points spatially, which is then harnessed to produce a cooling effect. This meta-analysis will focus on analysing parameters such as stack plate spacing and selection of a working fluid, in order to optimise the system. As this will directly impact the temperature gradient, as the temperature gradient is the core operator in the cooling process. The above parameters were examined with a combination of comparative and normalisation techniques, to synthesise data from varied experimental sources and produce accurate conclusions. The parameters investigated had differing effects on the system with regards to COPR and maximum cooling power, due to cooling power and input acoustic power increasing at different rates. The meta study concluded that a ratio of parallel-plate stack spacing to thermal penetration depth of (equation) was ideal for maximising cooling load, where as a ratio of approximately (equation) was ideal for achieving maximum COPR.
Effect of modified atmosphere package on biochemical properties of pomegranate (Punica granatum L.) fruits

Pomegranate (Punica granatum L.) is an important, as a table and processed fruit, due to its nutritional quality. An experiment was conducted to investigate the effect of different packaging material on chemical compositions of pomegranate fruits during storage. Pomegranate fruits were harvested from field washed with 150 ppm sodium hypochlorite, air dried, and graded based on uniformity (size, color, weight). Graded fruits were subjected to four modified atmospheric packaging treatments: 1) polyethylene; 2) polypropylene; 3) Xtend bag 4) Silver nano bag. Pomegranates fruits without packaging served as controls. All pomegranates were stored at 7 ± 2 °C and 90 ± 5% relative humidity for 100 days. MAP treated pomegranates maintained higher quality measurements compared to unpacked pomegranates. Overall, TSS, sugars and ascorbic acid decreased in all treatment groups with prolonged storage while, anthocyanin and antioxidant activity increased upto 60 days again decreased with prolonged storage, but the rate of decrease was highest in unpacked fruits. Overall, application of MAP maintained quality of pomegranate fruits up to 100 days compared to unpackaged fruits.
Understanding School Competition Under Voucher Regimes

I study how different voucher designs and policies affect school competition in education markets, and their consequences for students’ school choices and welfare. To that end, I build a structural model of demand and supply for primary education in markets that allow the use of vouchers. Unlike previous studies, I not only model schools’ pricing behavior, but also their program participation decisions, a discrete strategy that adds an additional layer of complexity to the solution of the supply side game. I fit my model to rich administrative data from Chile, and leverage its simultaneous implementation of universal (available to all students) and targeted (available only to low-income students) vouchers to estimate my model’s parameters. Counterfactual simulations indicate that universal and targeted vouchers affect school competition differently. On the one hand, a higher targeted voucher attracts more schools to participate in the targeted program. However, high-quality schools join only if the subsidy is sufficiently high. On the other hand, a higher universal voucher induces schools to lower the top-up fees they charge to parents. Specifically, a $1 increase in the subsidy translates into a $0.58 decrease in the average fee. Finally, policies that favor the universal voucher are more mobilityand welfare-enhancing in the aggregate, but increase the welfare gap between lowand high-income students, relative to policies favoring the targeted voucher. ∗Centro de Investigación Económica and Department of Economics, ITAM, e-mail: cristian.sanchez@itam.mx.

Effect of extrusion variables and chickpea flour incorporation on physical properties of Corn- cauliflower waste based extruded snacks

In the present study different levels of chickpea flour (10-40) were added to optimized level (90:10) of Corn and cauliflower waste blend. The independent variables included were composition (10-40), moisture content (9-13%), screw speed (137-387 rpm) and barrel temperature (85-185 C). Response variables were Bulk density, Expansion ratio (ER) and hardness. Response surface models were established to determine the responses as function of process variables. Results indicate that increase in composition leads to increase in bulk density, & hardness. Temperature had negative effect on Bulk Density, and hardness. Moisture had positive effect on Bulk Density and hardness.
PHYSICAL ACTIVITY LOGGER APPLICATIONS AMONG YOUNG ELDERLY

Digital wellness technologies have been proposed as a promising way to promote the levels of physical activity and to solve the prevalent problem of physical inactivity among elderly people. In this study, we propose and test a research model for explaining the acceptance and use of these technologies in the case of the young elderly segment (people aged 60–75 years) and physical activity logger applications. The proposed model is theoretically founded on UTAUT2, and it is empirically tested by using the data collected from 115 Finnish young elderly users of a physical activity logger application and analysed with partial least squares based structural equation modelling (PLS-SEM). We find habit to act as the strongest antecedent of use intention, followed by performance expectancy and hedonic motivation with approximately equally strong effects. In contrast, the effects of effort expectancy and social influence on use intention were found as statistically not significant. 568 33 RD BLED ECONFERENCE ENABLING TECHNOLOGY FOR A SUSTAINABLE SOCIETY
Automated Patch Correctness Assessment: How Far are We?

Test-based automated program repair (APR) has attracted huge attention from both industry and academia. Despite the significant progress made in recent studies, the overfitting problem (i.e., the generated patch is plausible but overfitting) is still a major and long-standing challenge. Therefore, plenty of techniques have been proposed to assess the correctness of patches either in the patch generation phase or in the evaluation of APR techniques. However, the effectiveness of existing techniques has not been systematically compared and little is known to their advantages and disadvantages. To fill this gap, we performed a large-scale empirical study in this paper. Specifically, we systematically investigated the effectiveness of existing automated patch correctness assessment techniques, including both static and dynamic ones, based on 902 patches automatically generated by 21 APR tools from 4 different categories. Our empirical study revealed the following major findings: (1) static code features with respect to patch syntax and semantics are generally effective in differentiating overfitting patches over correct ones; (2) dynamic techniques can generally achieve high precision while heuristics based on static code features are more effective towards recall; (3) existing techniques are more effective towards certain projects and types of APR techniques while less effective to the others; (4) existing techniques are highly complementary to each other. For instance, a single technique can only detect at most 53.5% of the overfitting patches while 93.3% of them can be detected by at least one technique when the oracle information is available. Based on our findings, we designed an integration strategy to first integrate static code features via learning, and then combine with others by the majority voting strategy. Our experiments show that the strategy can enhance the performance of existing patch correctness assessment techniques significantly.
The rice Aux/IAA transcription factor gene OsIAA18 enhances salt and osmotic tolerance in Arabidopsis

In plants, auxin/indoleacetic acid (Aux/IAA) proteins are transcriptional regulators, which regulate developmental process and responses to phytohormones and stress treatments. A previous study has shown that the rice Aux/IAA transcription factor gene OsIAA18 is induced by salt and osmotic stresses. However, little is known about the regulatory functions of this gene. In this study, the OsIAA18 gene was successfully cloned from rice. Subcellular localization analysis in onion epidermal cells indicated that OsIAA18 was localized to the nucleus. Expression analysis in yeast showed that the full length OsIAA18 exhibited transcriptional activation. Heterologous expression of OsIAA18 significantly enhanced salt and osmotic tolerance in transgenic Arabidopsis plants. Real-time quantitative PCR analysis showed that constitutive expression of OsIAA18 up-regulated genes involved in abscisic acid (ABA) biosynthesis, proline biosynthesis, stress responses, and reactive oxygen species scavenging under salt and osmotic stresses. Enzymatic analyses found that the transgenic plants had higher 9-cis-epoxycarotenoid dioxygenase, pyrroline-5-carboxylate synthase, superoxide dismutase, and peroxidase activities than wild-type plants under salt and osmotic stresses. In the transgenic plants, ABA and proline content significantly increased, whereas H2O2 and malondialdehyde content significantly decreased. In addition, the transgenic plants had also a lower electrolyte leakage and water loss rate. These overall results indicate that the OsIAA18 gene is involved in enhancing salt and osmotic tolerance in transgenic Arabidopsis plants. The OsIAA18 gene has a potential to be used to enhance the tolerance to abiotic stresses in other plant species.
The Linguistic Characteristics and Functions of Hashtags: #Is it a New Language?

Defined as a form of tagging that allows social media users to embed metadata in their posts, hashtags initially served to categorize topics and make them searchable online. Originating first on Twitter in 2007, hashtags have spread to other platforms, such as Instagram, Facebook, and Youtube. In addition to functioning as topic markers, hashtags have developed more complex linguistic functions. The ubiquity of this feature in the online medium, which now occupies a significant portion of our everyday communication is thus worthy of investigation. Although this topic has been researched in different disciplines, such as information diffusion, marketing, as well as sociology and public opinion, hashtags have not yet received enough attention from linguistic research. Using a sample of hashtags from a corpus of Instagram posts by Egyptian and Arab participants, this research thus aims to examine the characteristics of hashtags from a linguistic perspective, with particular focus on hashtags in the Arabic language. The study primarily seeks to determine the morpho-syntactic features of these recently emerging linguistic items according to the taxonomy proposed by Caleffi (2015). It also explores the pragmatic functions of hashtags based on Zappavigna’s (2015) view of hashtags as technologically discursive tools. The analysis points out that most of the hashtags in the data serve the experiential function and come as suffixes. The findings reveal both similarities and differences between English and Arabic hashtags.
Pott's Puffy Tumor: Intracranial Extension Not Requiring Neurosurgical Intervention

Pott’s puffy tumor, typified by a subperiosteal abscess underlying the frontal bone, is an uncommonly encountered clinical entity that can occur in the setting of local trauma or secondary to frontal sinusitis. Diagnosis can be challenging, as cultures may be sterile, and the condition must be differentiated from neoplasm and superficial and soft tissue infection. Although more common in the pediatric population, Pott’s puffy tumor must remain on the differential with a high index of suspicion in adult patients who fit the clinical picture. Early diagnosis with CT or MRI and therapeutic medical and surgical intervention are crucial as intracranial complications, such as abscess and empyema can occur and may be fatal. We present an adult patient with a history of inhaled drug abuse who presented with Pott’s puffy tumor with meningitis and bifrontal epidural abscesses at presentation. There is evidence in the literature that management of sinus-related intracranial epidural abscess with antibiotic therapy and adequate surgical or endoscopic surgical drainage may bypass the need for neurosurgical intervention, as was the case here.

Character association and path analysis for fruit yield and it’s contributing traits in cucumber genotypes (Cucumis sativus L.) under naturally ventilated polyhouse during off season

Ten cucumber genotypes were evaluated at B.C.K.V. under naturally ventilated polyhouse during 2016-17. This study was conducted to examine relationship between important traits of cucumber and their direct and indirect effects on yield. The relationships between fruit yield and yield components in cucumber genotypes were investigated as well as how those relationships changed with selection for improved fruit yield. In this study, genotypic correlation was higher than phenotypic correlations indicating the highly heritable nature of the traits. Correlation studies revealed that intermodal length has exhibited highly significant positive association with fruit yield per plant followed by fruit length, fruit weight, number of fruits per plant and vine length. Direct selection based on these traits would improve yield. The path coefficient analysis revealed that the days to fifty percent flowering, number of fruits per vine, internodal length, fruit weight, fruit length, fruit diameter, TSS and moisture percentage have direct positive phenotypic and genotypic effect on yield. Future breeding should focus on selecting the characters having direct effects to improve yield per plot.
Estimation of heterosis for grain yield and its related traits in maize (Zea mays L.)

Heterosis plays an important role in achieving improvement in crop production. 22 F1 hybrids obtained by crossing eleven lines and two testers in a line × tester fashion were used to derive the information on degree of heterosis over mid, better and standard check in maize. Twenty two crosses and their parents including one check Palam Shankar Makka-2 were evaluated in a Randomized Block Design with two replications. Grain yield per plant recorded the standard heterosis ranged from -62.54 (KI-13- 315 x HKI-1040) to 44.40% (KI-13-182 x HKI-1105) and significant positive standard heterosis recorded by five hybrids over the check viz., KI-13-182 x HKI-1105 (44.40%), KI-36 A x HKI-1040 (27.29%), KI-3A x HKI-1040 (19.71%), KI-7C x HKI-1040 (11.86%) and KI-13- 315x HKI-1105 (11.74%) These hybrids also showed high heterosis for many yield contributing traits in desirable directions. Therefore, these hybrids can be utilized in future for developing high yielding hybrids and inbreds having promising performance can be used in future maize breeding programs to exploit hybrid vigour.
Reading Assessment: Higher-Order Thinking Skills (Hots) through ICT

: Assessment in English language learning commonly addresses four broad topics; listening, reading, writing and speaking . Reading assessment in learning is very important because it give us information on how students understand the reading and utilize their ability to use the reading. Assessment includes three level namely: low level, medium level and high level. High level reading encompases higher order thinking skills (HOTS). This article aims to examine the relationship between higher order thinking skills (HOTS) in reading assessment and ICT (Information, Communication and Technology). ICT can be used as the media to develop the skills that students must have in HOTS in reading assessment. 21st-century skills require the learning of HOTS which consists of C4 (analyze), C5 (evaluate) and C6 (create). The C4 and C5 are considered critical thinking while C6 is creative thinking. Beside HOTS, ICT is also required in the era of education 4.0 which includes 21st-century skills. Thus, HOTS in reading assessment can be developed using ICT.
Morphology of Puccinia horiana Henn., the causal agent of chrysanthemum white rust occurred in West Bengal

Chrysanthemum is one of the most important flower crops in India. The chrysanthemum white rust (CWR) disease caused by Puccinia horiana (Henn.) was observed on chrysanthemum (cv. Meri Gold) in West Bengal for the first time. Initial symptoms was appeared light green to yellow, slightly raised spots mostly on the lower surface of leaves, which later, turned into pinkish brown to dark brown necrotic lesion surrounded with light green to yellow hallo. The fungus produced only two spore stages, teliospores and basidiospores. Studies under the microscopes revealed that the telial pustules were found mostly on the lower side of the leaves. The teliospores were thin walled, bicelled, pedicellate, pale yellow, oblong to oblong-clavate. The average size of teliospores was 47. 85μm X 13. 48μm. The teliospores could germinate frequently into a promycelium in situ, from the apical telial cell and were tubular, mostly segmented, club shaped. The basidiospores were oval in shape.

Analgesic Properties of Crude Aqueous Extract of Senna occidentalis Leaves in Wistar Albino Rats by Tail Flick Method

Senna occidentalis leaves were collected at Maiduguri Metropolitan Council (MMC) of Borno State, Nigeria and extracted in water by simple maceration method. The aqueous extract was tested for its analgesic activity in Wistar albino rats by tail flick method, where the result showed significant (P<0.01) increase in reaction time from 6.60±0.20 to 8.00±0.32 compared with the control (5.00±0.00) for the extract graded doses of 200 to 600 mg/kg, at 30 minutes post treatment; 7.20±0.37 to 8.60±0.24 compared with the control (4.60±0.24) for the same graded doses of the extract, 60 minutes post treatment; 5.60±0.24 to 7.60±0.24 compared with the control (4.60±0.24) for the same graded doses of the extract, 90 minutes post treatment; and 5.20±0.20 to 6.40±0.24compared with the control (4.60±0.24) for the same graded doses of the extract, 120 minutes. This study was carried out simultaneously with a standard drug (diclofenac 10mg/Kg) to compare the analgesic potency of Senna occidentalis crude extract, where 9.80±0.20, 11.40±2.04, 9.00±0.32 and 8.60±0.24 were recorded at 30, 60, 90 and 120 minutes respectively. The analgesic potency of Senna occidentalis leaves thus explains the successes seen when local people use it in treating different fever conditions. It was concluded that crude aqueous extract of Senna occidentalis has a good dose dependent analgesic activity in Wistar albino rats. It was recommended that use of Senna occidentalis leaves in the treatment of fever conditions should be encouraged, since the leaves are cheap, readily available and efficacious.
