Reducing Occupational Noise Propagated from Centrifugal Fan through Dissipative Silencers: A Field Study

Acoustic performance of dissipative silencer was evaluated to determine the effectiveness of perforated duct porosity and absorbent material density in reducing occupational noise exposure propagated from centrifugal fan. Design charts were applied to predict noise reduction and length of a dissipative silencer. Dissipative silencers with various punched duct porosity (14%, 30% and 40%) and sound absorbent density (80 Kg/m, 120 Kg/m, and 140 Kg/m) were designed and fabricated. According to ISO9612 and ISO11820, noise level was measured before and after installing all nine test silencers at fixed workstations around the discharge side of a centrifugal fan in a manufacturing plant. On average, the noise level at the discharge side of a fan without silencer was measured to be 93.6 dBA, whereas it was significantly mitigated by 67.4 dBA to 70.1 dBA after installing all silencers. Dynamic insertion loss for a dissipative silencer with 100 cm length was predicted to be 27.9 dB, which was in agreement with experimental ones. Although, there was no significant differences between insertion loss of silencers, the one with 30% porosity and 120 Kg/m rock wool density had the highest insertion loss of 26.2 dBA. Dissipative silencers noticeably reduced centrifugal fan noise exposures. Increasing sound absorbent density and duct porosity up to a certain limit could probably be effective in noise reduction of dissipative silencers.
Multi-Framework Reliability Approach

Despite advances in making datacenters dependable, failures still happen. This is particularly onerous for long-running “big data” applications, where partial failures can lead to significant losses and lengthy recomputations. Big data processing frameworks like Hadoop MapReduce include fault tolerance (FT) mechanisms, but these are commonly targeted at specific system/failure models, and are often redundant between frameworks. This article proposes the paradigm of dependable resources: big data processing frameworks are typically built on top of resource management systems (RMSs), and proposing FT support at the level of such an RMS yields generic FT mechanisms, which can be provided with low overhead by leveraging constraints on resources. We demonstrate our concepts through Guardian, a robust RMS based on Mesos and YARN. Guardian allows frameworks to run their applications with individually configurable FT granularity and degree, with only minor changes to their implementation. We demonstrate the benefits of our approach by evaluating Hadoop, Tez, Spark and Pig on a prototype of Guardian running on Amazon-EC2, improving completion time by around 68 percent in the presence of failures, while maintaining around 6 percent overhead.
Quantitative Analysis Of Cocaine Using Fourier Transform Infra Red Spectroscopy-Attenuated Total Reflectance: A Preliminary Investigation

In 2005 of twenty eight representative samples of cocaine taken from material seized by law enforcement officials in Trinidad and Tobago and submitted to the Trinidad and Tobago Forensic Science Centre were quantitatively analyzed using the Centre's standard technique of Gas Chromatography/ Flame Ionization Detection (GC/FID) as well as by Fourier Transform Infrared Spectroscopy/Attenuated Total Reflectance (FTIR/ATR). The both techniques used for the quantization of the cocaine content were statistically compared using the Paired t-test. The results indicated that the methods did not produce significantly different results and hence the FTIR-ATR technique was appropriate for the quantitative analysis of cocaine.
Specific Time Determinism: Circadian Rhythm of Microbial Community Assembly Patterns Under Common Light in Feces of Laying Hens

BackgroundAs an important part of biological rhythm, the circadian rhythm of the gut microbiota plays a crucial role in host health. However, few studies have determined the associations between the circadian rhythm and gut microbiota in laying hens. The purpose of this experiment was to investigate the circadian rhythm of the feces microbiota in laying hens.ResultsFeces samples were collected from ten laying hens at nine different time points (06:00-12:00-18:00-00:00-06:00-12:00-18:00-00:00-06:00) to demonstrate the diurnal oscillation of the feces microbiota. We described the phenomenon of circadian rhythmicity of the feces microbiota in laying hens based on 16S rRNA gene sequencing. According to the results, the α and β diversity of the feces microbiota fluctuated significantly at different time points. Beta Nearest Taxon Index analysis suggested that assembly strategies of the abundant and rare amplicon sequence variants (ASVs) sub-communities are different. Abundant ASVs preferred disperal limitation (weak selction), whereas rare ASVs randomly formed due to the “non-dominant” fractions. Highly robust circadian fluctuations were found, for instance, in Firmicutes and Proteobacteria, which fluctuated oppositely, and the total ratio remained in a dynamic balance over 48 h. We found that temporal dynamic changes had a significant effect on the relative abundance of the important bacteria in the feces microbiota community by using the random forest algorithm. Eight bacteria, Ruminococcus gnavus, Faecalibacterium, Ruminococcaceae, Enterococcus cecorum, Lachnospiraceae, Clostridium, Clostridiales, and Megamonas, gained rhythmicity. Interestingly, one unexpected finding was the fact that these eight bacteria all belong to Firmicutes. In particular, the microbiota profile appears to favor butyrate production, a common indicator of gut health, potentially through increases in the members of Lachnospiraceae, Faecalibacterium and Ruminococcaceae. The pathways were the functionalities that gained rhythmicity within the microbiota, which belonged to the most abundant functions, including xenobiotic biodegradation and metabolism, carbohydrate metabolism, and amino acid metabolism, which were consistent with the metabolic functions of amino acids and carbohydrates from feed.ConclusionThis study has shown that the defecation time could be among the important factors influencing the diversity, proportion, and functions of the feces microbiota community. We also note the potential application of beneficial microbial communities in livestock species, especially in the environment of raising antibiotic-free animals. These results provide references for further exploring the circadian rhythm of the gut microbiota in laying hens.
Collectivistic Leadership in Context: An Examination of How and When Collective Charismatic Leadership Relates to Unit Functioning

This research explores the nature of collective leadership by examining the boundary conditions of how and when it relates to unit functioning. Building from a contingency perspective that considers the impact of contextual factors, we propose that collective charismatic leadership will be associated with lowered unit conflict, and this relationship will be strengthened by the contingency elements of individual charismatic leadership, task complexity, and social inclusion. Furthermore, we propose that the interactions of collective charismatic leadership with these contextual factors will relate to performance and satisfaction through conflict. We examine our hypotheses across two unit-level field studies, and the results illustrated that high levels of these contextual factors enhanced the negative relationship between collective charismatic leadership and conflict, which generally mediated the relationships between these interactive effects and performance and satisfaction. The results also highlight the detrimental aspects of collective leadership and how it can relate to reduced unit functioning when it is not aligned with an appropriate context. Overall, these findings begin to provide a more complete picture of collective leadership from a contingency perspective through a greater understanding of when and how it is related to unit functioning.

In the present study, the pyrolysis behaviour of Capsicum Annuum stem Waste (CAW) was studied applying thermogravimetric analysis to evaluate the intrinsic kinetic parameters to develop a pyrolysis reactor for utilizing CAW. The thermal decomposition of CAW was achieved between 373 – 1173 K under inert conditions at different heating rates of 10, 20, and 30 K min. Model-free kinetic methods like KissingerAkahira-Sunose (KAS), Ozawa Flynn Wall (OFW) and Coats Redfern methods were applied to work out the kinetic parameters. To identify the utility of CAW and its biochar, physio-chemical characteristics such as proximate and ultimate analysis, scanning electron microscopy, and Fourier Transform Infrared analysis are reported.
Assessment of suitable seed treatment for improving storage potential of groundnut and sesame seeds

Groundnut and sesame are the economic commercial crops of India and need special attention for extended storage life due to its high demand and lesser multiplication ratio. The storage of oil seed is most critical both due to the presence of glycerides and amenability to fungal infections. The freshly harvested seeds of groundnut cv. TMV 13 obtained from Oilseeds Research Station, Tindivanam formed the base material for the study. The experiment was conducted at Oilseeds Research Station, Tindivanam during 2016-2017. The groundnut pods with initial moisture content of 8.0 per cent were conditioned to various treatments viz., T1- Control; T2 – Seeds treated with Halogen Vapour @3g/kg of seed; T3 – Seeds treated with Halo Polymer @3ml/kg of seed. After treating the seeds, the seeds were dried to the moisture content of eight per cent and packed in Super Grain Bag. Seeds were evaluated at bimonthly interval upto 6 six months of storage and from seventh month onwards it has been evaluated at monthly basis for its quality parameters viz., Germination Percentage, Root length (cm), Shoot length (cm), Dry matter production (g 10 seedling -1), Vigour index, Electrical Conductivity (dsm-1), Oil Content (Per cent) and Field Emergence (%). The groundnut as well as sesame seed treated with Halo polymer @3 ml/kg of seeds stored in super grain bag maintained better vigour and viability upto 10 months compared to other treatments under ambient condition. The groundnut maintained 53% and sesame maintained 85% at the end of ten months of storage.

Does the Order of Information Affect Investors' Investment Decisions? Experimental Investigation

Research aims: This study examines the order of information’s effect according to the Belief Adjustment Model. In particular, this study investigates the effect of the direction of the order and the pattern of presenting information in making investment decisions. Design/Methodology/Approach: The research applied an experimental method with web-based instruments using a 2x2 factorial design between subjects, involving 65 investors. Research findings: The investors’ investment valuation who received negative to positive information sequence direction was higher than the investors who received positive to negative information direction. Furthermore, there was an order effect in the form of recency on investors who received a partial presentation pattern. Meanwhile, investors who received a simultaneous pattern did not show an order effect in their assessment. These findings underline that the simultaneous pattern could reduce the order effect, so that investors need to generalize the information as a whole to avoid this bias. Theoretical contribution/Originality: This study extends the investigation of investment decisions using a long sequence of information perspectives and more varied types of information (e.g., financial information, corporate governance, and industry sectoral information that has an impact on company conditions) in making investment decisions on the belief adjustment model. Practitioner/Policy implication: Companies must maintain the direction of the order and the presentation patterns when issuing company information to maintain the quality of investors' decisions and avoid the risk of volatility in company shares. Research limitation/Implication: Participants who joined this research were active investors but had not yet had a comprehensive experience.
MicroRNA-21 Promotes Allergic Airway Inflammation and AHR and Inhibits Mesenchymal Stem Cell Migration in Cockroach Allergen Induced Asthma Model

BackgroundMesenchymal stem cells (MSCs) have been used to treat asthma in a mouse model. However, the efficacy and mechanism of MSCs are not elucidated. MicroRNAs (miRNAs) play a key rolein asthma and related to the aim of this study was to illustrate the role of miR21 and its influence on MSC migration in asthma model. MethodsA mouse model of asthma was established using cockroach extract (CRE), and miR-21 expression was examined. A miR-21 lentivirus construct was used to investigate the role of miR-21 in vivo and in vitro in mouse bone marrow-derived (BM-) MSCs. A TOPFlash reporter gene assay was used to study the signaling downstream of miR-21. IL-4, IL-5, IL-13, IgE, and IgG1 levels in bronchoalveolar lavage fluids were determined by enzyme-linked immunosorbent assays.ResultsMiR-21 was upregulated in CRE-induced asthmatic mice. MiR-21 promoted allergic airway inflammation and airway hyperreactivity by inhibiting BM-MSC migration. β-Catenin was found to act downstream of miR-21 as a negative regulator of miR-21. Rescue experiments verified that miR-21 inhibited BM-MSC migration by suppressing Wnt/β-catenin signaling.ConclusionMiR-21 promotes allergic airway inflammation and AHR and inhibits BM-MSC migration through Wnt/β-catenin signaling, which may serve as an effective therapeutic target for asthma.
Classification and Quantification of Human Error in Manufacturing: A Case Study in Complex Manual Assembly

Manual assembly operations are sensitive to human errors that can diminish the quality of final products. The paper shows an application of human reliability analysis in a realistic manufacturing context to identify where and why manual assembly errors occur. The techniques SHERPA and HEART were used to perform the analysis of human reliability. Three critical tasks were selected for analysis based on quality records: (1) installation of three types of brackets using fasteners, (2) fixation of a data cable to the assembly structure using cushioned loop clamps and (3) installation of cap covers to protect inlets. The identified error modes with SHERPA were: 36 action errors, nine selection errors, eight information retrieval errors and six checking errors. According to HEART, the highest human error probabilities were associated with assembly parts sensitive to geometry-related errors (brackets and cushioned loop clamps). The study showed that perceptually engaging assembly instructions seem to offer the highest potential for error reduction and performance improvement. Other identified areas of action were the improvement of the inspection process and workers’ provision with better tracking and better feedback. Implementation of assembly guidance systems could potentially benefit worker’s performance and decrease assembly errors.
Effect of integrated nutrient management on growth and yield of Yardlong bean (Vigna unguiculata (L.) Walp. Ssp. Sesquipedalis Verdc.)

The present investigation was carried out during Rabi season of 2018-19 to evaluate the effect of various sources of nutrients including organic, inorganic and biofertilizers on growth and yield of Yardlong bean (Vigna unguiculata ssp. sesquipedalis) cv. Arka Mangala. As regards the Gowth parameters the maximum vine length (2.61m), number of primary branches (7.60), terminal leaf length (16.57 cm), number of nodes per plant (19.37), were reported by application of 75% RDN through inorganic + biofertilizers (Rhizobium + PSB). In respect of yield per hectare and over all yield contributing factors, such as number of cluster per plant (48.30), pods per cluster (3.93), pod length (62.08 cm), pod girth (24.87 cm), pod yield (14.26t/ha) and seeds per pod (15.06) recorded significantly higher in the treatment of 75% RDN through inorganic+25% RDN through vermicompost + biofertilizers (Rhizobium + PSB). Thus growth and yield may be improved by integrated use of organic and inorganic sources of nutrients.
Prevalence of Temporomandibular Disorders and its Correlation with Stress and Salivary Cortisol Levels among Students

Objective: T o evaluate the prevalence of temporomandibular disorders (TMD) in students and to evaluate if any relationship existed between the stress levels, salivary cortisol levels, and TMD . Material and Methods: A total of 348 students, 187 female, and 161 male students, participated in this cross-sectional study. Students were evaluated based on the Research Diagnostic Criteria for TMD. The stress levels were evaluated using the Perceived Stress Scale. The students were divided into the control and TMD groups. Salivary cortisol levels in the salivary samples were analyzed. Results: The prevalence rate of TMDs was 30.7% in the study population. Of the female students, 61% had TMD compared with 46% of male students. Muscle disorders were the most predominant disorder in 14.2% of the students with TMD. The TMD group showed significantly higher salivary cortisol and stress levels than the control group. The TMD group also showed a moderate positive correlation between cortisol and stress levels (p=0.01). Conclusion: The study showed a strong association between salivary cortisol levels, stress, and TMD. Salivary cortisol could be used as a prognostic biomarker for stress while assessing the severity of TMJ problems in stressed individuals.
One-Visit Apexification in Management of Gutta Percha Extrusion and Condensing Osteitis: 4 Years Follow-Up

An overfilled root canal is the most common iatrogenic error in daily endodontic practice, especially on open apex tooth, which leads to chronic periapical inflammation and failure of endodontic therapy. With various materials and techniques available, the clinician must determine the ideal protocol to ensure successful endodontic treatment. This case report evaluates the outcome of the non-surgical, one-visit apexification using Mineral Trioxide Aggregate (MTA) of first maxillary incisor with an overfilled root canal, open apex, and condensing osteitis after four years follow-up. A 27-years-old woman was referred to Universitas Gadjah Mada Dental Hospital Yogyakarta due to biting pain and discoloration on first maxillary incisor with a history of trauma and endodontic treatment over 10 years ago. Periapical radiographs showed an overfilled open apex with condensing osteitis on the surrounding of the apex. Conventional endodontic retreatment was performed, followed by one-visit apexification using MTA. After 6 weeks, the biting pain relieved. Obturation and intracoronal bleaching then proceeded. Class IV composite was completed as a final restoration after 8 weeks of apexification. After 4 years follow-up, there was no sign and symptom and the condensing osteitis diameter reduced which indicated a successful treatment. This case supports the long-term evidence of former findings of the role of case selection, technique, and usage of MTA as one-visit apexification materials after a year follow-up. Furthermore, it provides a new perspective on the effect of MTA in the management of condensing osteitis. One-visit apexification using MTA is considered effective in the management of condensing osteitis due to gutta-percha extrusion in the
