Single-sensor field experiments in the Tarim basin, western China

Field: Earth and Planetary Sciences (Physical Sciences)

Single-sensor seismic acquisition has many benefits in theory and it has been widely used in the Middle East and offshore over the last decade. To determine whether single-sensor seismic acquisition is feasible in the Tarim basin, we have conducted five single-sensor field experiments corresponding to five kinds of terrain in 2015 and 2016. The single-sensor and the conventional geophone array were planted on the same receiver lines and on the same location, and then acquired the seismic data simultaneously. A one-to-one comparison between single-sensor data and geophone array data was conducted for each of the five experiments. The results show that the seismic data acquired by single-sensor are almost the same as that by geophone array in the mountainous areas, but of much lower S/N ratio than that by geophone array on the other four terrains. In order to obtain seismic sections with the same quality as that acquired by geophone array, tens of times higher fold-of-coverage (means tens of times higher shot density) is needed while using single-sensor and it is not economically feasible on the other four terrains where dynamite rather than vibroseis is widely used as source.
From Nativeness to Strangeness and Back: Ascribed Ethnicity, Body Work, and Contextual Insiderness

Field: Social Sciences (Social Sciences)

This article offers a reflection on a certain variant of broadening the position of “being inside” with some “buts,” or through “within but.” Drawing on my field experience in the Ukrainian diaspora in Canada, I discuss the context-dependent, fluid and labile insiderness and the case of using a researcher’s embodied distinctions (senses, ethnicity, class) in the research site created by the fieldwork participants, and not the researcher him/herself. My considerations are embedded with the dialectics (not opposition) of the insider–outsider and point to the contextual “nativeness” and “strangeness” of the researcher. I also discuss the fluidity and contextuality of a researcher’s field familiarity, as well as when s/he conducts research in cooperation with “their own people,” as well as circumstances and factors that transform this familiarity into strangeness. I argue that the latter, instead of being an obstacle or barrier in the research, is a beneficial and mind-opening ethnographic tool.
OPTICAL, MAGNETIC AND ELECTROCHEMICAL PROPERTIES OF SPINEL MN3O4, CO3O4 NANOSTRUCTURES

Field: Materials Science (Physical Sciences)

Manganese oxide (Mn3O4) and Cobalt oxide (Co3O4) nanocrystals were synthesized using a straightforward and cost-effective combustion method. Structural analysis through X-Ray Diffraction, FTIR Spectroscopy, and Raman Spectroscopy confirmed structure to be tetragonal for Mn3O4 with space group of I41/amd (141) and the cubical for Co3O4 with space group Fd3m (227). The usual microscopic crystal sizes were determined using the Debye Scherer formula, resulting in approximately 14 nm & 22 nm for manganese oxide and cobalt oxide respectively. Scanning electron microscopic pictures displayed irregular and uniform spherical grains for Co3O4 and Mn3O4 respectively, with typical grain sizes of 120 nm & 100 nm. EDS and XPS spectra showed clear binding energy peaks for Mn, Co, and O2, confirming the chemical purity of the samples. The optical band gap of the nanocrystal Mn3O4 and Co3O4 were 2.93 eV, 2.50 eV respectively. Magnetic analysis revealed a sturdy ferromagnetic nature at 5 Kelvin temperature for both Mn3O4 and Co3O4 nanocrystals. Electrochemical investigations demonstrated that Mn3O4 nanocrystals exhibited excellent performance as electrodes for electrochemical capacitors. At a current density of 0.5 Ampere/g, they achieved higher specific capacitance of 417 Farad/g, maintaining nearly 100% coloumbic efficiency after 600 cycles and displaying decent cyclical stability for upto ten thousand cycles. Alternatively, Co3O4 showed inferior electrochemical behavior, indicating that Mn3O4 nanocrystals possess superior mass transport of electrolyte ions into the electrode, making them more suitable for electrochemical capacitors.
The Concentration of Prostaglandin E2 in Periradicular Lesions

Field: Medicine (Health Sciences)

Prostaglandins (PG) have been implicated in pathogenesis of periapical lesions. The purpose of this study was to determine the concentrations of PGE2 in human periapical lesions. Periapical specimens from patients with clinical signs and symptoms of chronic and acute apical periodontitis were obtained and immediately frozen in liquid nitrogen. Periradicular tissues from unerupted third molars were frozen and used as controls. The concentration of PGE2 was determined by radioimmunoassay. Low levels of PGE2 were found in the control tissues as compared to those detected in chronic and acute lesions. A significantly higher level of PGE2 was found in acute lesions in comparison to those found in chronic lesions. The results show that acute lesions have higher concentrations of PGE2 than chronic lesions. The findings indicate that this substance participates in pathogenesis of human periapical lesions.
Speed Control of Direct Current Motors

Field: Engineering (Physical Sciences)

Direct current (DC) motors are used in variable-speed drives to produce a high starting torque, and provide speed control over a wide range of speed. Controlled rectifiers are popularly employed in the speed control of DC motors. In this paper, the speed control of separately excited dc motor, using single-phase, full-wave, fully-controlled rectifier was investigated. Controlled rectifiers were used to produce variable DC output voltages from a fixed alternating current (AC) voltage. Since the armature voltage (Va) of a DC motor is the output of a single-phase controlled rectifier, it was varied by varying the delay or firing angle (αa) of the rectifier. The field circuit also requires a rectifier to control the field current (If) or flux by varying the firing angle (αf). In this paper, the motor speed equations were derived. The output equations of the rectifiers were also derived and incorporated into the motor speed equations. The graphs generated from these equations show clearly how the speed of the DC motor varies with the output voltage or current of the controlled rectifiers. Thus, motor speed, being a function of the armature voltage (Va), or the field current (If) was controlled. This paper demonstrates the control strategies of a separately excited dc motor, using single-phase controlled rectifiers.

O Norte do Paraná: do café à cana do açucar

Field: Social Sciences (Social Sciences)

Este artigo aborda o processo de povoamento do norte do Paraná, pilotado pela empresa britânica Paraná Plantation ltd., que, no período de 1930 a 1950 implantou cidades, definiu um modelo de estrutura fundiária de pequenos lotes, motivou a forte cafeicultura do norte do Paraná, mas que não resistiu às crises de mercado, às intempéries do clima e à política brasileira de reordenamento do espaço rural e sucumbiu. Após sucessivas tentativas de sustentar o desenvolvimento regional, a partir do binômio soja-trigo e da policultura se observa, a partir do PROÁLCOOL (1974), a expansão da cana-de-açúcar para produção de etanol. Para diagnosticar as dinâmicas territoriais a partir da implantação da Usina Santa Terezinha no município de Terra Rica/Noroeste do Paraná utilizamos as imagens LANDSAT TM 5 dos anos de 2000, 2005, 2008 e 2011. As imagens foram corrigidas geometricamente e manipuladas no Spring 5.06.
A knowledge-based hybrid modeling approach to planning problems in flexible manufacturing systems.

Field: Decision Sciences (Social Sciences)

Flexible manufacturing systems (FMSs) have the potential to achieve both flexibility and productivity in manufacturing: versatile machines, automatic tool interchange capabilities, and automated material handling equipment allow FMSs to simultaneously manufacture a large variety of parts in small to medium batch sizes without negatively affecting production rates. However, this potential has not been fully exploited because of a failure to completely deal with the increased complexity of FMSs, which involve more constraints and decision alternatives than conventional manufacturing systems. This research proposes a knowledge-based hybrid modeling (HM) approach to solve complex FMS planning problems. Specifically, an HM is developed to effectively consider due date constraints in solving the part type selection and production ratio problems. Although "meeting due dates of customer orders" is an important FMS operation criterion, previous approaches to the problem have not addressed due dates effectively. The HM combines a constraint satisfaction problem (CSP) search, a rule-based simulation model, and heuristic rules. The HM approach is "knowledge-based" in that knowledge-representation methods are employed to build and solve the HM. The problem-solving process of the HM approach consists of following four stages. (1) Generation. A CSP search finds a candidate solution which satisfies a set of constraints. Being formulated as a CSP, the part type selection and mix ratio problems are concerned with assigning production ratios to orders subject to certain heuristic constraints. (2) Evaluation. A rule-based simulation model evaluates the candidate solution in terms of expected tardiness of orders. (3) Choice. A choice rule selects the best solution based on the evaluation results. (4) Learning. A learning rule refines the heuristic constraints based on the evaluation results so as to prune unnecessary CSP searching space more closely. The performance of the HM is compared with that of previous analytic models. The comparisons are made by conducting simulation experiments in a particular FMS context. The comparison results indicate that the hybrid model significantly improves FMS performance in terms of mean tardiness.
Associations between sleep duration, insomnia, depression, anxiety and registry‐based school grades: A longitudinal study among high‐school students

Field: Psychology (Social Sciences)

Summary This study explored the prospective associations between sleep patterns, mental health and registry‐based school grades among older adolescents. In the spring of 2019, 1st year high‐school students in Western Norway were invited to a survey assessing habitual sleep duration, insomnia, depression and anxiety. Sleep patterns, depression and anxiety were assessed using the Munich ChronoType Questionnaire, the Bergen Insomnia Scale, the Patient Health Questionnaire‐9, and the Generalized Anxiety Disorder‐7. Students consenting to data linkage with the county school authorities were re‐invited 2 years later. Registry‐based grade point averages for each of the included school years were accessed through the school authorities. The final longitudinal sample included 1092 students (65.1% girls; initial mean age 16.4 years). Data were analysed using linear mixed models. Longer school night sleep duration and less severe symptoms of insomnia, depression and anxiety were all associated with higher grade point averages at baseline in crude analyses. Shorter school night sleep duration, as well as more severe symptoms of insomnia and depression at baseline, all predicted worse grade point averages at 2‐year follow‐up when controlled for baseline grade point averages. [Correction added on 30 December 2024, after first online publication: In the preceding sentence, the word “better” has been corrected to “worse”.] By contrast, anxiety symptomatology at baseline was unrelated to changes in grade point averages over time. The longitudinal associations between school night sleep duration and insomnia symptoms on grade point averages were significant also when adjusted for sex and baseline symptoms of depression and anxiety. These findings indicate that shorter school night sleep duration and more severe insomnia symptoms predict lower grade point averages development over time, irrespective of co‐existing symptoms of depression and anxiety.
BalticLSC: A low-code HPC platform for small and medium research teams

Field: Computer Science (Physical Sciences)

Research teams often face problems with insufficient resources to develop and execute their computation algorithms. This is due to limited access to professional programmers and High Performance Computing centres. This paper presents a platform that uses a new visual language to solve these problems. It uses high-level abstractions to define the flow of data and the execution of computation modules in a distributed computation environment. The runtime system follows the rules of low-code, where the development is on-line and highly simplifies the deployment of apps. This way, even small research teams can easily gain access to high-end computation resources and develop and share their applications.
Use of pedicled omentum in oesophagogastric anastomosis: analysis of 100 cases.

Field: Medicine (Health Sciences)

According to reports from our country, leakage occurs in about 5% of oesophagogastric anastomoses despite the numerous improvements in operative techniques, including methods of anastomosis in recent years. From October 1979 to May 1984, 128 cases of oesophageal or gastric cardiac cancer were operated on, and pedicled omentum was used to reinforce the oesophagogastric anastomosis in 100 cases, without any postoperative anastomotic leakage.
Dermal Delivery of a SARS-CoV-2 Subunit Vaccine Induces Immunogenicity against Variants of Concern

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

The ongoing coronavirus disease 2019 (COVID-19) pandemic continues to disrupt essential health services in 90 percent of countries today. The spike (S) protein found on the surface of the causative agent, the SARS-CoV-2 virus, has been the prime target for current vaccine research since antibodies directed against the S protein were found to neutralize the virus. However, as new variants emerge, mutations within the spike protein have given rise to potential immune evasion of the response generated by the current generation of SARS-CoV-2 vaccines. In this study, a modified, HexaPro S protein subunit vaccine, delivered using a needle-free high-density microarray patch (HD-MAP), was investigated for its immunogenicity and virus-neutralizing abilities. Mice given two doses of the vaccine candidate generated potent antibody responses capable of neutralizing the parental SARS-CoV-2 virus as well as the variants of concern, Alpha and Delta. These results demonstrate that this alternative vaccination strategy has the potential to mitigate the effect of emerging viral variants.
Hamstring Pain - Football Player

Field: Medicine (Health Sciences)

HISTORY: An 18 year-old high school football player presented with posterior thigh pain after dead-lifting heavy weight. He reported several months of progressive aching pain and tightness in his right hamstring. When standing, he had limited forward flex at the hip without also flexing his knee. He experienced no improvement with conservative treatment. Initial physical therapy focused on hamstring stretching, eccentric hamstring loading, deep tissue massage, and self-massage with a foam roller. PHYSICAL EXAM: There was tenderness to palpation of right hamstring. Pain was also reproduced with passive range of motion of the hamstring. With the knee flexed, the patient could flex, internally rotate, and externally rotate the hip without limitation. Forward flexion of the lumbar spine was limited to 10-15 degrees with reproduction of posterior thigh pain. Also, with attempted straight leg raise, he would lift his hip to prevent flexion at the hip. Manual muscle testing revealed 5/5 strength throughout his L2-S2 myotomes. Muscle stretch reflexes were 2+/4 at the knee, medial hamstring, and ankle bilaterally. DIFFERENTIAL DIAGNOSIS: - Hamstring strain - S1 Radiculopathy - Sacroiliac joint inflammation TESTS AND RESULTS: - Posterior thigh pain was exacerbated by slump sit testing, and cervical extension provided significant symptom reduction. - His popliteal angle measured 70 degrees on the left side and 30 degrees on the right side. The pain in his hamstring worsened with cervical flexion while checking the popliteal angle. - Straight leg raising was painful at the 30 degrees on the right side, made worse with cervical flexion. - There was also tenderness to palpation over the L5-S1 paraspinal musculature. - MRI of the lower limb which was intepreted as normal. - MRI of the lumbar spine noting a disk extrusion at L5-S1 on the right. WORKING DIAGNOSIS: - L5-S1 disk extrusion with S1 radiculopathy TREATMENT AND OUTCOMES: - Right S1 transforaminal epidural steroid injection. - Immediate improvement in symptoms post-injection. - Complete resolution of symptoms when evaluated for clinical follow-up. - Prescribed regimen of physical therapy with focus on centralization (if symptoms were to recur), core stabilization, and lumbar strengthening for return to high level functionality and eventual heavy weight-lifting.
Analysis of a Network of Non-Identical Parallel-Connected Supercapacitors

Field: Engineering (Physical Sciences)

Supercapacitors are widely used in various applications ranging from wind turbine pitch control systems to regenerative braking in electric and hybrid vehicles. This is due to their unique properties including high power density, scalability, high reversibility, and long operational lifetime. Although it is well-known that associating non-identical supercapacitors in parallel increases the equivalent capacitance of the network at a constant voltage, their dynamic behavior in the time domain remains under-explored. However, this cannot be simply done using the models of ideal capacitors, because supercapacitors exhibit a combined resistive-capacitor, dispersive nature. In this work, we analyze the behavior of supercapacitors connected in parallel (two or more different devices) in both the time and frequency domains using the constant phase element (CPE) as the building model. The CPE has a fractional impedance of the form z ( s ) = ( C α s α ) − 1 with C α a positive constant representing a pseudocapacitance, and α a dispersion coefficient that takes values between zero and one. From our theoretical analysis we obtain explicit expressions for the power-law-like voltage response of the supercapacitor network under constant current excitation in terms of the generalized Mittag-Leffler function. The derived formlæ are validated by experimental time and frequency-domain data of real commercially-available devices.
Molecular Characterization and Antimicrobial Resistance Pattern of Escherichia coli Recovered from Wastewater Treatment Plants in Eastern Cape South Africa

Field: Immunology and Microbiology (Life Sciences)

Wastewater treatment plants (WWTPs) are designed to eliminate organic matter and pathogens but most WWTPs discharges antimicrobial resistance pathogens into aquatic milieu. The study aimed to examine the antibiotics resistant patterns and the presence of some resistance genes among E. coli isolates from WWTPs effluents. Water were collected from WWTPs final effluents, filtered through nitrocellulose membrane and the filter papers were placed on chromogenic agar plates, incubated for 24 h at 37 °C. Presumptive E. coli isolates (173) were obtained from the culture method. From the presumptive E. coli isolates screened by polymerase chain reaction (PCR), 111 isolates were positive and the positive isolates were further screened for six diarrheagenic E. coli pathotypes (EPEC, ETEC, EHEC, DAEC, EIEC, and EAEC) and from the pathotypes screened, nine isolates harboured daaE gene. The phenotypic susceptibility patterns of the 111 isolates to 12 antibiotics were determined by Kirby-Bauer disk diffusion technique. All the isolates were resistant to erythromycin and clindamycin. From the resistance genes screened, 31 isolates harboured mcr-1 gene and nine isolates harboured ermA gene. The study reveals that water samples recovered from the final effluents of WWTPs may likely be one of the major sources of antibiotic-resistant in Escherichia coli.
THE IMPLEMENTATION OF TEACHER’S PREPARATIONIN TEACHING ENGLISH AT ANAK SALEH KINDERGARTEN MALANG

Field: Social Sciences (Social Sciences)

To make a successful teaching and learning process, the teacher needs a preparation before teaching in class. It means that teaching preparation has the important role in teaching and learning process. A teaching preparation describes the elements that will be used in teaching a
language course and provides the basis for instructional focus and content. This research intended to investigate the implementation of teacher’s teaching preparation in teaching English at Anak Saleh Kindergarten Malang. More specifically, this research is focused on the
implementation of teacher’s teaching preparation and the problems faced by the teacher in implementing it.
This research used descriptive qualitative design because it was intended to describe the phenomena about the teacher’s teaching preparation at Anak Saleh Kindergarten Malang. The subject of this research was the teacher who teaches English at Anak Saleh Kindergarten Malang. The teacher was chosen because she is the only one teacher who teaches English program there. Besides, the informant was qualified to give information about the teaching
preparation and she also used it in teaching­learning activity. To collect the data, the researcher used observation, interview, and teacher’s document (teacher’s teaching preparation). The data were analyzed by comparing the teachers’ document with the observation done by the researcher. Then to complete the data, the researcher conducted the interview with the teacher. The result of this research showed that the teacher’s teaching preparation in Anak Saleh Kindergarten Malang was implemented well by the teacher. However, in conducting the teaching activities, there were some points that did not implement by the teacher, they were no vocabulary
spelling in the second observation because the vocabularies were written in Indonesian words and in the third observation the teacher did not give the teaching activities like art work, work sheet, game, and song because the students condition was very crowded and the time was limited. In implementing the teacher’s document, the teacher was elaborated it into three teaching phases, they were pre teaching, whilst teaching, and post teaching.
In conclusion, the teachers’ teaching preparation in Anak Saleh Kindergarten Malang is implemented well by the teacher.
