Authors: Do Thanh Dung , Le Manh Cuong , Nguyen Tuan Anh , Le Thai Hung
Published: August 2022

Fused Deposition Modeling (FDM) 3D printing is one of the most popular 3D printing technology today and its products is always interested to improving their mechanical properties by printed engineering parameters. In this study, the influences of infill density and printing pattern on mechanical properties of FDM 3D printing structure have been studied on some common printing materials including Acrylonitrile Butadiene Styrene (ABS), Polylactic Acid (PLA), carbon fibre reinforced PLA composites (PLA-CF). Each material is printed with different patterns such as hexagonal, square, triangular, zigzag structures at 15% infill. Particularly for the triangle printed structure of ABS, there are three infill densities at 15 %, 25 % and 40 %. The experimental process has evaluated the strength and deformation of the printing patterns. The results have shown that the influence of printing patterns on compressive strength are significant because of the relationship between printing patterns and sample weight. Besides, infill density also have a great influence on the compressive strength of 3D printed products.

Published: August 2022

The improper management of plastic waste has become a silent killer in the marine ecosystem. The scientific evidence of plastic accumulated in marine biota and entering the food web have urged quick actions against the plastic pollution. The plastic detection algorithms developed using satellite images can proclaim emission, transportation, weathering and accumulation of plastic that is vital in eliminating them. This study developed an index to find floating marine harvested macro plastic within Sentinel 2 ACOLITE and Sen2Cor images. This index preserved the plastic information protected the plastic information and maximized the separation of them from the surrounding objects. The identified plastic pixels were analysed using scatter plots to discriminate plastic from non-plastic objects and to observe the characteristics. The index and the scatter plot analysis detected the plastic pixels with bottle percentages more than or equal to 14%. The plastic bags and the fishing nets required around 50% pixel percentage to be detected. The plastic pixels with 100% plastic coverage were located as a separate cluster in the scatter plots. Therefore, the accurate detection of plastic pixels using ACOLITE and Sen2Cor images depends on the pixel plastic percentage and plastic coverage. The Sen2cor images classified plastic pixels according to their pixel plastic percentage for two dates. However, this classification was not successful for other dates with aerosol, clouds and smooth sea surface conditions which made the plastic signal weak. The ACOLITE and Sen2Cor atmospheric corrections are not suitable for plastic detection when the plastic signal is weak.

Published: August 2022

Context: Athletic trainers (ATs) are comparatively underpaid relative to peer healthcare professionals. While many factors contribute to salary and benefits of a given employment position, negotiation is a factor of the final salary and benefits package that is achieved. It is unclear to what extent ATs negotiate salary or other terms of employment during the hiring process. Objective: To explore the negotiation practices of ATs during the hiring process. Design: Cross-sectional. Setting: Web-based survey. Patients or Other Participants: 587 ATs employed in the clinical setting that previously held at least one full-time employment position. Main Outcome Measures: Independent variables included several demographic factors as well as current salary range. Dependent variables were participants' responses to various survey items focused on experiences with salary and terms of employment negotiation. Summary statistics were used to characterize all variables and multiple chi-square analyses (p<.05) were performed to determine significant influences of independent variables on negotiation practices. Results: More than half of ATs did not attempt to negotiate their salary (57.6%), and almost three-quarters of ATs did not negotiate terms of employment (70.5%) during the hiring process. The most successfully negotiated terms were moving expenses (72.3%) and continuing education funding/reimbursement (62.7%). The influence of demographic factors on negotiation and negotiation success varied with significant findings for: number of previous full-time employment positions, gender, marital status, salary range, and number of dependents. Conclusions: It is alarming that more than half of ATs do not negotiate salary or terms of employment during the hiring process. While widespread training on negotiation practices is warranted, our findings suggest it would be most beneficial for early-career and women ATs. ATs must become comfortable with negotiating salary and terms of employment in order to effect change on the average salary and employment status of those in the profession.

Authors: Jain Anshul , Mittal Ashok , Sharma Sanjya , Deep Akash
Published: August 2022

Background:

Combined spinal–epidural technique is a widely accepted and popular modality for labor analgesia. Opioids are being used as adjuvants since long time. Dexmedetomidine is a new drug that is being used as an intrathecal adjuvant.

Aim:

The study aims to compare the safety and efficacy of fentanyl and dexmedetomidine as intrathecal adjuvants in labor analgesia.

Settings and Design:

This was a continuous, prospective, randomized controlled trial with 120 parturients.

Materials and Methods:

After ethical approval and written consent, participants were divided randomly into two groups: Group A – bupivacaine 2.5 mg (0.5 mL diluted to 2 mL) + 20 μg of dexmedetomidine in 1 mL saline intrathecally (total volume: 3 mL) and Group B – bupivacaine 2.5 mg (0.5 mL diluted to 2 mL) + 15 μg of fentanyl in 1 mL saline intrathecally (total volume: 3 mL). Primary outcomes were satisfactory analgesia, mode of delivery, and neonatal outcome. Participants were monitored for the onset and duration of analgesia, degree of motor block, and maternal and fetal side effects.

Results:

A total of 108 parturients reported sufficient analgesia (Group A: 57; Group B: 51), and 74 patients delivered vaginally (Group A: 41; Group B: 44). The rates of normal vaginal delivery were higher in Group B. Group A reported earlier onset of analgesia (61.26 ± 18.23 s) that lasted for longer duration (124.16 ± 26.23 min) than in Group B. There were no serious side effects in any of the groups. Fetal ultrasound revealed attenuation of fetal heart rate variability. The heart rate of newborns was also found to be low in Group A.

Conclusion:

Chances of vaginal delivery are higher with intrathecal fentanyl as an adjuvant. Intensity and duration of analgesia are better with intrathecal dexmedetomidine.

Authors: Kumar L. Mano , George Rinu J. , Mohanan Manikantan
Published: August 2022

Background and Objectives:

Globally, suicide is a pertinent public health crisis that affects almost all nations cross-culturally. Suicide is one of the leading causes of death in many countries, even before the COVID-19 pandemic hit worldwide. India, a nation developing rapidly, is also not free from the leashes of suicide deaths. COVID-19 augmented the rate of suicide due to multifaceted determinants. Adequate empirical evidence about data on suicide is also scarce.

Materials and Methods

This review synthesizes determinants, available demographic correlates, and reported rates of suicide published in the Indian context. The authors conducted a thorough literature search to find published English free full-text scientific articles related to suicide during the COVID-19 pandemic in the Indian context. Databases relied on for literature were PubMed, Google scholar, and PLOS one databases using comprehensive search strategies to avail the maximum number of studies.

Results

Ten out of 76 studies available in the initial search were analyzed thoroughly for ruling out determinants, rates, and sociodemographic correlates of suicide. Fear of COVID-19 infection, financial crisis, mental breakdown, and job loss are cardinal reasons attributed for suicide, and male suicides are more prevalent in this arena.

Interpretation and Conclusions

Findings portray factors such as fear of COVID-19 diagnosis, apprehension to become infected, financial crisis, loss of job, and isolation are some of the significant determinants quoted out. The study points out the need for multifaceted policies in preventing this public health crisis.

Published: August 2022

Background:

The uncontrolled spread of the COVID-19 disease in India's second wave post-February 2021, put to task the public health system across the nation. This, in turn, exhausted our health-care workforce both physically and mentally. To establish the prevalence of psychological symptoms and guide the action plan in place, the present study was undertaken among COVID-19 health-care workers (HCWs) at tertiary-care public hospital, Mumbai.

Materials and Methods

The present cross-sectional study was conducted after due institutional ethical clearance among 212 HCWs engaged in the management of COVID-19 patients during the second wave. A Google Form® was created in English, Hindi, and Marathi languages for self-administration. Data were collected under three domains; informed consent, sociodemographic and workplace-related details, and DASS-21 Questionnaire scores. This was further subjected to statistical analysis using SPSS® software.

Results

This study included 90 (42.5%) doctors, 91 (42.9%) nurses, and 31 (14.6%) other categories of HCWs. Depression was prevalent in 44.3% HCWs, while 43.9% and 36.3% of the HCWs were affected by anxiety and stress, respectively. Younger population, female gender, and doctors were associated (P < 0.05) with an increased likelihood of either of the prevalent psychological symptoms. Other significantly associated (P < 0.05) factors included COVID-19 vaccination status of the HCW, history of COVID-19 infection, infected colleague at workplace, workplace housing facilities and commute, number of dependents on the HCW and hospitalized family member or close friend.

Conclusion

The COVID-19 HCWs were found to be under considerable psychological strain. In essence, screening, identifying, and effectively targeting HCWs for psychological interventions is needed to protect and strengthen the health-care system.

Authors: Verma Lavkush , Agarwal Vivek , Arya Amit , Gupta Pawan Kumar , Mahour Pooja
Published: August 2022

Context:

There is a dearth of studies on the risk of gaming addiction (GA) in children and adolescents with disruptive behavior disorders (DBDs) and its comorbidity with attention-deficit hyperactivity disorder (ADHD).

Methods

Seventy participants aged 6–16 years diagnosed with ADHD and DBD were included in this cross-sectional, observational study and compared with 40 healthy controls. They were assessed for clinical details of gadget type, duration of use, and purpose on a semi-structured questionnaire. The intensity of video gaming was assessed using Game Addiction Scale (GAS). Behavioral symptoms were assessed on Child Behavior Checklist (CBCL). Descriptive statistics with t-test, analysis of variance, and Pearson's correlational analysis were used as applicable.

Results

Use of gadgets for video games for ≥ 4 hours was found to be significantly higher (P = 0.001) in cases (61.5%) than in controls (10%). Most of the cases used Internet for communication (69.4%) and entertainment (58.3%). A significantly higher number of cases (37.1%) fulfilled criteria for video game addiction and the numbers were significantly higher in ADHD + DBD groups as compared to only ADHD or only DBD group. Children with GA had significantly higher scores in all domains of CBCL as compared to those without GA. The GAS score had a significant positive correlation with aggressive behavior, social problems, rule breaking, and attention problem domains of CBCL.

Conclusions

GA was significantly higher in ADHD and/or DBD than normal children and adolescents. Comorbidity of ADHD and DBD further increases the risk of GA. Therefore, children with these disorders should be screened routinely for GA.

Published: August 2022

Introduction:

Irony comprehension (IC) has been described as a schizophrenia (SCZ) disease marker. High variability exists in the measurement of IC. We aimed to assess content and “known-groups” validity of an Indian, comic-based, computerized-IC task.

Methods

A 15-story IC task was prepared. Content validity of the IC task stimuli was assessed by experts in mental health. Performance on the IC task was compared between 15 SCZ patients and 15 healthy controls (HC). Known-groups validity was assessed using discriminant function analysis.

Results

Content validity of the IC task was optimum. Lower number of correct responses and longer reaction times for irony stimuli were seen in SCZ patients, compared to HC. Both these measures showed 100% accuracy in discriminating SCZ from HC, therefore, implying excellent “known-groups” validity.

Conclusion

The newly designed IC task has good psychometric properties, in terms of content and “known-groups” validity.

Authors: Pendharkar Shreyas Shrikant , Telgote Shilpa Avinash
Published: August 2022

Lurasidone is a novel atypical antipsychotic with additional antidepressant and pro-cognitive properties. The drug has shown good efficacy in treatment of schizophrenia as well as bipolar disorder. It is currently used as monotherapy as well as adjunctive therapy with Lithium or valproate, due to its lower propensity of cardiometabolic side effects and endocrinological adverse effects. Extra pyramidal side effects and akathisia with lurasidone therapy are reported in a minority of patients, but very few instances of tardive dyskinesia with lurasidone therapy are reported so far.

Published: August 2022

Clozapine, a second-generation antipsychotic, is known to have a significant effect on the cardiovascular system, especially on blood pressure. Previous reports show about 4% incidence of clozapine-induced hypertension. However, there are very few cases reported in females. We report a case of clozapine-induced hypertension in a 30-year-old female diagnosed with schizophrenia. When she showed no response to two antipsychotics, clozapine was started. Within a few days, she developed hypertension, not manageable with simultaneous use of antihypertensive medication. Her blood pressure returned to normal after stopping clozapine. Hence, it is important to take appropriate measures to check for rare side effects like hypertension in patients receiving clozapine and to evaluate for all other possible causes.

Published: August 2022

Timor deer (Rusa timorensis) is native species in Indonesia that faces many threatening issues. Studies related to the health aspects of Timor deer are considered essential to provide some information related to deer health management in captivity. Deer handling procedures in captivity in Indonesia are commonly carried out with physical restraint. Physical restraint in animals is known to cause various changes in animals’ clinical and hematological values. This study aimed to determine the clinical and hematological parameters of Timor deer under physical restraint in captivity. This study used ten Timor deer that consisted of five stags and five hinds. The deer was positioned in a chute, then continued with the physical examination and blood sampling. Parameters observed in this study are clinical and hematological parameters. This study showed that clinical parameters of Timor deer under physical restraint have significant differences between sex groups, except for respiration rate parameters. Hematological parameters of physically restrained Timor deer did not show significant differences between sex groups, except for basophil parameters. This study concluded that physical restraint could affect the clinical and hematological parameters of Timor deer.

Published: August 2022

Three species of groupers, including tiger grouper (Epinephelus fuscoguttatus), humpback grouper (Cromileptes altivelis), and leopard coral grouper (Plectropomus leopardus), have been successfully cultivated. However, the constraints on larviculture that have been described still arise in the hatchery. This study compares several hatchery parameters in these three grouper species representing three different genera (Epinephelus, Cromileptes, and Plectropomus). The egg incubation and larval rearing were carried out in a concrete tank (3 x 3 x 1.2 m3) filled with 6-7 m3 seawater. Eggs were stocked with a density of 100,000 eggs/tank. The grouper larvae were reared until they became juvenile. The eggs were incubated until they were hatched in the same container and media as larval rearing. Larvae were reared until 60 dah (days after hatching), and data were taken from the rearing for three cycle's larval culture. Management of grouper larval rearing follows the Good Fish Hatchery Method (Cara Pembenihan Ikan yang Baik/CPIB) based on Indonesian National Standard (Standar Nasional Indonesia/SNI). The experimental parameters were egg diameter, hatching rate, larvae mouth opening width, survival activity index (SAI), larvae development, and total body length growth. The several hatchery parameters in three grouper fish species are significantly different. The tiger grouper has the best larval performance.

Published: August 2022

Previous research showed that Stichopus hermannii and Spirulina platensis had an antioxidant activity. It is indicated by the reduced malondialdehyde (MDA) level in the liver of the diabetic rats. However, the STZ administration did not significantly increase MDA concentration of diabetic rats' blood serum for 14 days. This research aimed to determine in vitro and in vivo MDA inhibition of S. hermanii and S. platensis. The in vitro antioxidant activity test was conducted using the MDA-TBA method, and a positive control used α-tocopherol. For in vivo experiment, diabetic rats (DM) were induced by streptozotocin for 21 days. Twenty-five rats which were divided into five groups: normal rat group (NA), diabetic rat group (DA), diabetic rat group + glibenclamide (DG), diabetic rats + Stichopus hermanii (SH), and diabetic rats + Spirulina platensis (SP). The in vitro results showed that the antioxidant activity of 25 ppm Spirulina platensis had the same MDA inhibitory activity as 200 ppm α-tocopherol, but 200 ppm Stichopus hermanii had lower inhibition than 200 ppm α-tocopherol. The in vivo result showed that Stichopus hermanii treatment was more effective in suppressing blood serum MDA concentration, but Spirulina platensis was more effective in suppressing liver MDA concentration.

Protease contributes significantly to various industrial sectors, as shown by its increasing demand. An indigenous previously isolated bacteria, Bacillus halodurans CM1, is a wild-type bacterium whose ability to produce alkalotermophilic protease. In this study, the transformation of methylated pBBRE194 plasmid containing alkaline protease gene from this strain (PBBRE194-prot-CM1) into itself using a conjugation approach was conducted, and the measurement of the alkaline protease activity of the recombinant bacterium was carried out. The recombinant B. halodurans CM1 has been verified to carry the methylated pBBRE194 prot-CM1 by examining its ability to degrade protein in media containing skim milk and tetracycline, but also by amplifying tetracycline resistance gene sequence with 1,024 bp length of plasmid pBBRE194 prot-CM1 by PCR method from the recombinant bacterium. The results confirmed that recombinant B. halodurans CM1 was positively harboring plasmid pBBRE194 prot-CM1. Alkaline protease produced by recombinant CM1 reached higher activity than wild type between 18-36 h of cultivation. The alkalotermophilic wild type B. halodurans could accept the recombinant plasmid into their cells via conjugational transformation is firstly reported to our further knowledge.

Published: August 2022

Epstein-Barr Virus can cause various diseases, from acute inflammatory diseases such as fatal or chronic EBV infection, infectious mononucleosis as well as lymphoid and epithelial cancer, various autoimmune diseases, and also could interact with malaria. As EBV infects 95% of the world population, and more than 30% are infected with the protozoan parasite, with more than 500,000 deaths due to malaria cases. It is important to understand how EBV dysregulates the immune system, especially when the virus is interacting with other pathogens such as malaria parasites, causing more severe conditions in certain people like Burkitt Lymphoma. This review will be informative about the mechanism of how EBV interacts with malaria parasites and how it affects the immune system. Knowledge of various cytokines triggering the immune system which may provide links to control/minimize malaria disease severity.

Transient gene expression is an important technique in gene functional analysis, protein production and in plants. However, traditional transient expression methods using Agrobacterium are time-consuming with low efficiency. In this study, we demonstrated the use of a single-walled carbon nanotube (SWCNT) to deliver 35S:mCherry:pCXSN plasmid into rice calli. This transient expression protocol used a plastic medical syringe to create the physical pressure to help the delivery of plasmid DNA into plant cells. This protocol is relatively easy to perform and low cost. The transient expression was observed under fluorescence microscopy, and the mCherry fluorescence signal was quantified. The plasmid DNA was delivered into the rice cell using a 3:1 ratio (plasmid: carbon nanotube). The result showed that the mCherry signal of carbon nanotube + plasmid DNA treatment was the highest signal at 3 days post-transformation and decreased to a lower signal at 6 days post-transformation. Moreover, the quantitative analysis of mCherry mean intensity revealed that the signal intensity of carbon nanotube + plasmid DNA treatment was the highest level, and significantly higher than the control treatments at 3 days post-transformation. Plasmid DNA can be transported easily into plant calli using this carbon nanotube transient  expression protocol.

Published: August 2022

Soil temperature measurements from a Soil Climate Analysis Network (SCAN) monitoring site in the Ozark Highlands Major Land Resource Area (MLRA 116A) were evaluated on landscapes comprising Typic Fragiudults (Scholten series) and Typic Paleudults (Poynor series). The five soil forming factors were similarfor both soils, with the major difference between the adjacent soils being a fragipan in the Scholten series. Air and soil temperatures were collected from a weather station of the USDA-Natural Resources Conservation Service near the border of the mesic soil temperature regime and udic soil moisture regime zone. The mean annual soil temperature observed in the Scholten soil (13.5° C) was0.5° C cooler than the mean annual soil temperature in the Poynor soil (14.0° C). This study showed little difference in mean soil temperatures between soiltypes from January to April and from August to December. During the months of May, June and July, the Poynor mean soil temperature was higher (by 1.1° C, 1.4° C and 1.2° C, respectively) than the Scholten mean soil temperature.According to this study, it is possible that the mean annual soil temperature of fragipan soils is cooler than adjacent soils with no fragipan properties. Thegreatest differences between mean soil temperature and mean air temperature were observed during the months of November (5.1° C for Scholten soil and 5.3°C for Poynor soil); December (5.0° C for Scholten soil and 4.9° C for Poynor soil); and January (4.5° C for Scholten soil and 4.4° C for Poynor soil). The smallestdifference was during the month of March (0° C for Scholten soil and 0.3° C for Poynor soil). This study also indicated that the mean annual soil temperature in the Ozark Highlands can vary by soil series depending on soil properties affecting heat transfer within pedons.

Published: August 2022

Drought mortality of juvenile trees is a major cause for failure ofreforestation projects. Portable devices such as passive radiative dew condensers can often provide 0.15 L/day of water in situ, possibly sufficient for tree survival until roots can access groundwater, allowingself-sustainability. To evaluate growth and survivability of juvenile trees of Tabebuia heterophylla Britton and Swietenia macrophylla King under suchlow water amounts, juvenile trees received approximately 0.033, 0.067, 0.134, 0.201 and 0.268 L/tree/day, representing fractions (relative evapotranspirationor RET) of 0.125, 0.25, 0.50, 0.75 and 1.00 of the evapotranspiration demand (ETo). The experiment lasted 60 days for S. macrophylla and 90 days for T. heterophylla. All T. heterophylla juvenile trees survived even at the lowestirrigation rate. However, S. macrophylla juvenile trees began dying at RET < 0.5, with only 60 percent surviving at RET = 0.25 (0.067 L/day) and 100 percentmortality occurring at RET = 0.125 (0.033 L/day). Water requirements of 0.134 L/day, necessary for full survival of both species, were within the typical production capacity of 1-m2 dew condensers. However, a greater safetyfactor is obtained using drought tolerant species such as T. heterophylla, which can survive under water application rates as low as 0.03 L/day.

Published: August 2022

In Puerto Rico, the most commonly planted citrus crops are oranges, mandarins and limes. Farmers still have an interest in citrus production despite the detrimental effect of the Huanglongbing (HLB) disease on island orchards. Vector control and use of slow-release fertilizers (SRF) and soluble fertilizer (SF) applications to the soil are among the recommended management practices to increase citrus production. In 2009, the Department of Agriculture of Puerto Rico (DAPR) appointed the fruit tree specialist from the University of Puerto Rico and a DAPR staff member to evaluate the condition of citrus production in Puerto Rico. Based on that evaluation, DAPR developed an initiative to increase the number of marketable fruits of oranges, mandarins, and limes from trees between five and 12 years of age by promoting the use of SRF in combination with SF applications to the soil. An experiment was established during 2011 in a seven-year-old ‘Tahiti’ limeorchard in Ciales, Puerto Rico, to compare fertilization methods promoted by the DAPR with conventional methods, estimating the profitability of each method. The DAPR fertilizer recommendations were developed specifically for situations where HBL is present. In the orchards under study, HBL was not observed and therefore not tested. This does not mean that trees were not infected because symptoms may take months or years to become visible. The fertilization methods evaluated were: (1) granular fertilizers applied every four months (conventional fertilization), (2) manual application of SRF twice a year plus the application of SF to the soil with a backpack sprayer four times a year (SRF+SF/backpack), (3) manual application of SRF twice a year plus the application of SF to the soil with a motorized sprayer four times a year (SRF+SF/motorized), and (4) manual application of SRF twice a year. Total fruit number, total fruit weight, and average fruit weight were measured. Harvests were carried out monthly for 15 months. In the first seven harvests, the performance of trees submitted to the combination of SRF and SF was more efficient than was conventional fertilization or SRF alone, since the same production was maintained using a considerably lower amount of nutrients. At 14 months, the application twice a year of SRF alone almost doubled yield although the effect of this treatment was inconsistent during the year. We estimate that the combination of SRF and SF applications to the soil will result in the highest profitability with an income of $27 per tree per year and a profitability of $8.05 per dollar spent.

Experimental and Analytical Study of Silica Particles on Self-Healing Concrete
Authors: Reddy Kamasani Chandrasekhar , Kumar Krishnaiah gari Hemanth
Published: August 2022

This study aims to investigate the properties of green concrete made with ground granulated blast-furnace slag (GGBS), Robo sand (RS), and coconut shell (CS). GGBS is the mineral admixture used to replace cement. Nano-silica particles (NSPs) and CS are used as coarse aggregates, and RS is the fine aggregate used to replace river sand. The workability, mechanical properties, and durability properties of green concrete are investigated and compared with those of conventional concrete (CC). Test results show that the cement replaced with 30% GGBS and 3% NSPs exhibits superior strength. The compressive and splitting tensile strengths are increased by 24.03% and 42.32% after 28 days of curing, respectively. The workability is improved by 12.22% (slump) and 13.25% (compaction factor) after 28 days of curing. The sorptivity of HM3 (3.26%) is lower than that of CC due to the uniform distribution between particles. Microstructure evolution is carried out to identify concrete mix behavior.
