Stem Cutting Growth of Red Dragon Fruit (Hylocereus costaricensis) due to Aplication of Cow Manure and KCl in Andosol

This study aims to obtain the optimum dose of manure for red dragon fruit plant growth on Andosol, optimum K fertilizer dose for red dragon fruit plant growth on Andosol, and the interaction of manure and K fertilizer for red dragon fruit plant growth on Andosol. This research was conducted from August 2018 to November 2018 at the Horticulture Seed Center, Kepahiang Regency, Bengkulu Province. This study used a completely randomized design (CRD) consisting of two factors with three replications. The first factor is cow manure, which is 0 g/polybag, 20 g/polybag, 40 g/ polybag, and 60 g/polybag. The second factor is K fertilizer, which is 0 g/polybag, 1.38 g/polybag, 2.76 g/polybag, and 5.52 g/polybag. The results showed that the application of cow manure with a dose of 60 g/polybag resulted in the best shoot growth time and shoot fresh weight
Punching shear provisions for reinforced and prestressed concrete flat slabs

The validity of the CSA A23.3-94 code provisions for punching shear were compared with the punching shear results of 142 reinforced concrete flat slabs, 16 prestressed concrete flat slabs with unbonded tendons, and 17 flat slabs with unbonded prestressed and supplementary bonded reinforcement. The code prediction equations are not capable of direct verification against experimental results without using a correction factor. Using a justifiable correction factor, the CSA A23.3-94 provisions are appropriately conservative for reinforced concrete slabs but the scatter is large. However, it was concluded that the CSA A23.3-94 provisions are not conservative for prestressed concrete flat slabs. An equation is proposed to calculate the punching shear capacity of reinforced concrete and prestressed concrete slabs, which has a smaller coefficient of variation than the punching shear provisions of CSA A23.3-94, for symmetrically loaded interior columns. The critical section of the proposed method is the perimeter .
Depressive symptom trajectory following romantic relationship breakup and effects of rumination, neuroticism and cognitive control

Abstract Studying individuals who recently experienced a romantic reltionship breakup allows us to investigate mood disturbances in otherwise healthy individuals. In our study, we aimed to identify distinct depressive symptom trajectories following breakup and investigate whether these trajectories relate to personality traits and cognitive control. Subjects (n = 87) filled out questionnaires (RRS‐NL‐EXT trait rumination and NEO‐FFI neuroticism) and performed cognitive tasks (trail making test, Stroop task) during a period of 30 weeks. To identify distinct depressive symptom trajectories (‘trajectory groups’), we performed K‐means clustering on the consecutive (assessed every 2 weeks) Major Depression Inventory scores. This resulted in four trajectory groups; ‘resilience’, ‘fast recovery’, ‘slow recovery’ and ‘chronic distress’. The ‘slow recovery group’ and the ‘chronic distress group’ were found to have higher neuroticism and trait rumination levels compared to the ‘resilience group’, and the ‘chronic distress group’ also had higher neuroticism levels than the ‘fast recovery group’. Moreover, the ‘chronic distress group’ showed worse overall trail making test performance than the ‘resilience group’. Taken together, our findings show that distinct patterns of depressive symptom severity can be observed following breakup and that personality traits and cognitive flexibility seem to play a role in these depressive symptom patterns.
The whipping vibration of large high speed catamarans

This paper reports on a study into the whipping behaviour of large high-speed aluminium catamarans and its influence on fatigue life. Full-scale measurements of slam events and exciter tests have been conducted on two large high-speed catamarans to investigate the modes, frequencies and damping of their vibratory whipping response. A corresponding theoretical modal analysis was also conducted utilising finite element analysis and including fluid-structure interaction. Good correlation between the predicted and measured frequencies and mode shapes was found. The influence of forward speed on the added mass formulation was found to be negligible, while vessel loading conditions were found to have a significant influence on modal frequencies. Results are also presented from a fatigue study which highlight the influence of whipping on fatigue life.
A comparative study of plate fixation versus titanium elastic nail in treatment of displaced midshaft clavicle fractures

Background: In the last few decades, there has been an increasing trend towards operative treatment for displaced midshaft clavicular fractures. These fractures are managed by plate fixation and titanium elastic nailing system, but the optimal fixation method for these types of fractures remains a topic of debate. The aim of this study is to compare functional outcome of displaced midshaft clavicle fractures treated with locking compression plate and titanium elastic nail system and its associated complications. Material and Method: 40 patients treated with plating and titanium elastic nailing system between October 2019 and March 2021 were analyzed. They were randomized in two groups (20 in plate group and 20 in titanium elastic system group). Clinical and radiological assessments were performed at the 6 th week, 3 rd and 6th month postoperatively. The functional outcome was assessed by Constant- Murley score. Both surgical techniques were compared in terms of radiological union, clinical functions and complications associated. Result: Earlier union and functional outcome scores were better for the Titanium elastic nail system group than plating group ( p < 0.01). The rate of complications was higher in the plate group compared with the Titanium elastic nail system group. Conclusion: In treating displaced midshaft clavicle fractures Titanium elastic nailing system is superior to clavicular plating. Titanium elastic nailing system technique is safe, minimally invasive and has better functional outcome, faster union, fewer complication and cosmetically more acceptable than plating.
Long-Term Clinicoradiological Outcomes of Cervical Fusion With Polyether Ether Ketone versus Cervical Disc Arthroplasty in a Double-Blinded Randomized Control Trial

Introduction: In this double-blinded randomized controlled trial, we compare the long-term clinicoradiological effects of anterior cervical discectomy and fusion with polyether ether ketone implant (ACDF with PEEK) versus artificial cervical disc (cervical disc arthroplasty [CDA]) in patients with single and bilevel cervical degenerative disc disease (CDDD). Aims: We aimed to compare the pain scores, cervical kinematics, and radiological outcomes in patients undergoing CDA and ACDF for single and bilevel CDDD over 5 years. Settings and Design: This study was carried out from 2010 to 2019 in the Neurosurgery Department of a Tertiary Care Hospital attached to a Medical College in India. Subjects and Methods: We enrolled 30 patients in each group. Clinical and radiological assessments were carried out for all patients over a period of 5 years. Statistical Analysis Used: Wilcoxon Signed-rank test, Mann–Whitney U-test, and Fischer's exact test were used for comparing the preoperative and follow-uP values. R software version 3.6. 0 was used for statistical analysis. Results: A significant improvement in the cervical range of motion, sagittal range of motion (ROM), and functional spinal unit (FSU) was observed in the CDA group at final follow-up, while the PEEK group reported a significant decrease in the ROM and FSU and the difference between the two groups was also found to be statistically significant. Conclusions: When assessed over 5 years following surgery, we found CDA to be superior with respect to ROM, FSU, overall cervical alignment, and maintenance of disc height when compared to ACDF with PEEK implant.
The Effects of an Eight Week Plyometric-based Program on Motor Performance Skills and Muscular Power in 7–8-Year-Old Primary School Students

Background of Study: Competence in motor performance skills is important in enabling children to be physically literate. Plyometric-based training has been suggested as an effective means to enhance motor performance skills in young athletes. However, no studies have reported the effects of a whole body plyometric-based program integrated into physical education on motor performance skills with young children. Objective: This study aims to examine the effect of a plyometric-based program on primary school students’ motor performance skills, upper and lower body muscular power, and reactive strength index. Method: The sample was composed of 61 primary school students, 29 girls and 32 boys, aged 7–8 years old, from two second-grade Physical Education (PE) classes. Both groups participated in their regular eight-week PE lessons (50-minute classes twice a week). During the study, the plyometric group performed a plyometric-based program in the 15-minute warmup of each class, while the comparison group performed regular warmup activities. Student’s motor performance skill proficiency, reactive strength index, lower and upper body muscular power were assessed before and after the eight weeks of PE lessons. The data were analysed using a two-way analysis of variance, followed by pairwise comparisons with the Bonferroni adjustment. Results: The data analysis indicated significant increases in motor performance skill proficiency, upper and lower body muscular power in the plyometric group vs comparison group (p ≤ 0.05). Conclusion: These results suggest that including a plyometric-based program in the PE warmup phase of the lessons may improve motor performance skills and muscular power in primary school students.
The peculiarities of patients with COVID-19 infection

Background: The surge demand and decreased availability of the health workers determined the designation of the Clinical Municipal Hospital of Phthisiopneumology (CMHP) into a hospital for the case-management of COVID-19 patients during the period of December 2020 – April 2021 for the treatment of the mild cases. The aim of the study was to assess the main peculiarities of the patients with COVID-19 through a cross-sectional study developed during the period February-April 2021 in the CMHP. Material and methods: A cross-sectional, analytical and prospective study was realized, which included 145 patients with COVID-19 hospitalized in the CMHP during February-April 2021. The inclusion criteria were: patient older 18 years, COVID-19 infection diagnosed by the pulmonologist with the positive polymerase chain reaction result for SARS-CoV-2 (COVID-19) and signed informed consent. Results: The peculiarities of patients with COVID-19 were dominated by the female sex, age over 60 years, residence in the urban districts of Chisinau and the infection acquired in the Republic of Moldova. Common clinical manifestations were: high temperature, profuse sweats, asthenia and headaches, productive cough, dyspnea, loss of smell or taste, and sore throat. The typical radiological findings such ground-glass pattern or consolidation with bilateral multifocal involvement were most frequent. Were cured most of the patients and the death rate was low. Conclusions: Peculiarities and clinical manifestations of the patients admitted in CMHP were typical for the COVID-19 infection. These findings did not show the real outcome of the standard case-management of the COVID-19 due to the restricted admission criteria.
Development of antimicrobial resistance due to the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new coronavirus identified in 2019. This disease, which may cause a serious respiratory infection, has been designated an international public health emergency and is being treated with several types of antivirals, antibiotics, and antifungals. While society works hard to combat the coronavirus disease 2019 (COVID-19) pandemic, it is equally vital to be prepared for the outbreak’s notorious effects on the development of antimicrobial resistance (AMR). Antibiotic misuse and overuse are predicted to have serious ramifications for antibiotic stewardship programs and AMR management worldwide. Importantly, the global influence on the creation of novel antimicrobial resistance is uncertain due to a paucity of data on antimicrobial usage during the COVID-19 pandemic. The current pandemic might be a useful tool for depicting the spread of antimicrobial resistance and underlining the difficulties in managing the issue once it has emerged. This review aims to assess available data on bacterial infections in coronavirus-infected patients and to offer insight into the development of AMR in the face of the current public health issue.
A view on limit cycle bifurcations in relay feedback systems

The paper is concerned with the study of oscillations in linear dynamic systems with relay feedback. The specific interest is about the bifurcations of these periodic solutions, with regard to phenomena which also occur in smooth systems and to others due to the relay discontinuity. The followed approach moves from the describing function method, leading to results which are approximate in nature but which express in a simple and correct way the essential mechanisms of the studied phenomena, as shown in the proposed examples.
Effects of Excessive Soil Water Conditions on Sugarcane Yields

ABSTRACT Astress-day-index model was developed to relate sugarcane yield to stresses caused by excessive soil water conditions. Stress was quantified by the sum of excess water above the 45 cm depth, SEW45. Crop susceptibility factors were estimated for three stages of growth from published data from flooding studies. Relative yields from a four-year drainage experiment in Southeastern Louisiana were plotted as a function of calculated stress-day-index values. Additional data were obtained from published results on a controlled flooding experiment in Louisiana. A regression analysis of all the data resulted in YR = 100 - 0.03 SDIW, where YR is the relative yield and SDIW is the stress-day-index due to wet conditions.

In this study a Physica UDS200 plateplate rheometer was used to investigate rheological behavior of table spreads exposed to repeated breaks in the cooling chain. The instrument was utilized as a nondestructive measurement tool giving rheological information when repeating a number of time/temperature cycles.
EVALUATION OF INNOVATIVE TEACHING AND LEARNING STRATEGIES IN SCIENCE EDUCATION: COLLABORATIVE WORK AND PEER ASSESSMENT

This paper presents the design of the curricular unit "Nature Integrated Sciences I” for the Course of Primary School Teachers of the 1st cycle of Higher Education at the University of Aveiro (Portugal). This curricular unit integrates a holistic approach to science based on the STS movement, where the activities promote collaborative work, such as study visits, field trips, laboratory classes, public presentations of works, discussion activities and self-and peer-assessment. It is intended to evaluate innovative teaching and learning strategies by hearing the students’ opinions about the proposed activities, their attitudes towards collaborative work and peer assessment. A questionnaire was applied online during the currilucar unit and the results show that most students felt that the teaching methodology was appropriate, group activities were relevant and assessment strategies contributed to the development of the targeted skills and building of knowledge. Key words: collaborative work, peer assessment, science education.
Neural defensive circuits underlie helping under threat in humans

Empathy for others’ distress has long been considered the driving force of helping. However, when deciding to help others in danger, one must consider not only their distress, but also the risk to oneself. Whereas the role of self-defence in helping has been overlooked in human research, studies in other animals indicate defensive responses are necessary for the protection of conspecifics. In this pre-registered study (N=49), we demonstrate that human defensive neural circuits are implicated in helping others under threat. Participants underwent fMRI scanning while deciding whether to help another participant avoid aversive electrical shocks, at the risk of also being shocked. We found that higher engagement of neural circuits that coordinate fast escape from self-directed danger (including the insula, PAG and ACC) facilitated decisions to help others. Importantly, using Representational Similarity Analysis, we found that the strength with which the amygdala and insula uniquely represented the threat to oneself (and not the other’s distress) predicted helping. Our findings indicate that in humans, as other mammals, defensive mechanisms play a greater role in helping behaviour than previously understood.
Concerted modification of nucleotides at functional centers of the ribosome revealed by single-molecule RNA modification profiling

Nucleotides in RNA and DNA are chemically modified by numerous enzymes that alter their function. Eukaryotic ribosomal RNA (rRNA) is modified at more than 100 locations, particularly at highly conserved and functionally important nucleotides. During ribosome biogenesis, modifications are added at various stages of assembly. The existence of differently modified classes of ribosomes in normal cells is unknown because no method exists to simultaneously evaluate the modification status at all sites within a single rRNA molecule. Using a combination of yeast genetics and nanopore direct RNA sequencing, we developed a reliable method to track the modification status of single rRNA molecules at 37 sites in 18S rRNA and 73 sites in 25S rRNA. We use our method to characterize patterns of modification heterogeneity and identify concerted modification of nucleotides found near functional centers of the ribosome. Distinct, undermodified subpopulations of rRNAs accumulate upon loss of Dbp3 or Prp43 RNA helicases, suggesting overlapping roles in ribosome biogenesis. Modification profiles are surprisingly resistant to change in response to many genetic and acute environmental conditions that affect translation, ribosome biogenesis, and pre-mRNA splicing. The ability to capture single molecule RNA modification profiles provides new insights into the roles of nucleotide modifications in RNA function. Highlights method enabling single-molecule profiling of RNA modifications is developed and reveals heterogeneous classes of modified ribosomes. rRNA 2’O methylation and pseudouridylation modifications are independent of each other. in functional centers of the ribosome are modified in a concerted fashion. of function for RNA helicases Dbp3 and Prp43 produce discrete overlapping subpopulations of incompletely modified ribosomes. modification profiles are resilient to rapidly changing nutrient conditions and perturbation of translation
Compression-Compression Fatigue Performance of a Fire Resistant Eco-Core

Eco-Core, a fire resistant core material for sandwich composite structures developed under the US Navy (ONR) program, was used to study its compression-compression fatigue performance at a sinusoidal cyclic load of frequency 2Hz, load ratio R = 0.1, 0.2 and density range of 0.526 to 0.541 g/cc. Under compression fatigue loading, Eco-core was found to deformed in three stages- onset of failure or formation of crush band depictedly small increase in compliance (Stage-1), crush band growth (Stage-11) and abrupt increase in compliance or the final failure(Stage-111), which was characterizing as the fatigue life of the Eco-core. Fatigue damage, onset and growth that leading to final failure was happened mostly in the middle or edge of the specimens. This failure behavior is same as that of static loading.The fatigue stress-life (S-N) data showed that the endurance limit was 0.7So and 0.8So for panels tested with stress ratio of 0.1 and 0.2. The compliance stress expressed in cyclic stress(Δσ) was about 0.64So, which is independent of R ratio in the test.
On the scalability of private and pooled on-demand services for urban mobility in Amsterdam

ABSTRACT The emergence of on-demand transport services is set to change the mobility landscape in urban areas. This study investigates the potential scalability of an on-demand mobility system to substitute motorised trips performed by private cars and public transport in Amsterdam, The Netherlands. We adopt an agent-based simulation framework and investigate scenarios where either private and pooled on-demand services replace private car trips, public transport trips, or both private car and public transport trips. Service performance in terms of level of service offered and operational efficiency are analysed. Results indicate that pooled on-demand services fare better than private on-demand in terms of veh-km travelled and the empty drive ratio. Private on-demand services generate 43%, 38%, and 44% more veh-km than pooled on-demand services when on-demand services replace car trips, public transport trips, or car and public transport trips, respectively. However, private on-demand services offer shorter total travel times than pooled on-demand for all scenarios.
The Effects of A Short-Term Detraining on Anthropometric, Hormonal and Functional Factors in Male Wrestlers

The aim of this study was to assess Anthropometrical and body composition and functional changes after a short term of detraining. Materials and Methods: 10 wrestlers (weight 57.1±20.72 kg, height 171.4±4.92 cm, age 22.30±1.41yr) which were experienced in national college competitions were selected for this study. Detraining period consisted of sedentary days for 3-week. Assessments for body mass and composition, girth measurements, vertical jump performance, muscle strength, anaerobic power, and resting hormonal concentration were performed in the present study. The values obtained before and after the detraining period were compared using Student"s paired and un-paired t-test. Results: Findings has shown that 3-week detraining period caused significant changes in VO2max and Peak and Mean anaerobic power in wrestlers, while this intervention did not result in significant effect in body composition, anthropometrical, hormonal and performance. Conclusion: present study showed that 21-day of detraining in wrestlers led to decrease aerobic power, Peak and Mean anaerobic power. However, this detraining period could not affect organs circumference, body fat percent, body weight, agility, strength and growth hormone. From the present findings, we can conclude that three weeks of detraining in wrestlers showed significant reduction in aerobic and anaerobic power.
