The Immediate Effect of Static Hamstring Stretching on Dynamic Balance and Gait Biomechanical Variables in Athletes With Hamstring Tightness: A Preliminary Study
Authors: Salemi Parsa , Shadmehr Azadeh , Fereydounnia Sara
Published: November 2021

Introduction: Flexibility is an essential component of muscle function, and insufficient muscle flexibility may lead to muscle injuries. Decreased hamstring flexibility is one of the frequently reported risk factors for a hamstring strain and diminished athletic performance. Stretching is a commonly used intervention for increasing muscle length. There is a lack of evidence concerning the possible effects of hamstring stretching in balance and gait biomechanics. So, this study was designed to investigate the potential effects of static hamstring stretching on the range of motion (ROM), dynamic balance, and biomechanical variables of gait in athletes with hamstring tightness.
Materials and Methods: This study is a single-group, pretest-posttest clinical trial performed on semi-professional female athletes. Twelve female athletes aged 20 to 35 years with bilateral hamstring tightness received a single session of unilateral static hamstring stretching on their randomly selected side. All subjects were assessed for straight leg raise, popliteal angle (using standard goniometry), perceived hamstring tightness (using a visual analog scale). They completed single-leg standing and 15-m walking and running tasks before and immediately after the intervention. The biomechanical parameters, including gait-line length, swing duration, and stance duration in walking tasks, maximum total force and mean total force in running task, and center of pressure (COP) displacement and standard deviation during balance task were measured using OpenGo sensor insole system. The pre-post values were compared using the paired sample t-test, and the level of significance was 0.05.
Results: The values for straight leg raise and popliteal angle significantly increased (P<0.05) compared with the baseline, while perceived tightness significantly decreased following stretching (P<0.001). The amplitude (P₌0.006) and standard deviation (P₌0.016) of COP displacement in the mediolateral direction during the single leg stance balance task were significantly decreased after the intervention. Stance duration in slow walking (P₌0.004), as well as stance duration (P₌0.012) and swing duration (P<0.001) in fast walking, were significantly decreased (P<0.05) after stretching. No change was observed in gait biomechanical variables during the running test (P>0.05).
Conclusion: The results of this study indicate that static hamstring stretching can be a promising intervention not just for increasing hamstring flexibility but also for improving balance ability.
Comprehension of Complex Structures by Persian-speaking Aphasics: The Role of Cognitive Load
Authors: Azad Omid
Published: November 2021

Introduction: So far, many studies have investigated the extent and nature of the grammatical deficit in aphasia. However, to the best of our knowledge, this research is the first in the Persian language to inspect the comprehension of patients with Broca’s aphasia on diverse syntactically complex structures.
Materials and Methods: To scrutinize the impact of task on aphasics’ performance, four age-, education- and gender-matched Persian-speaking patients with Broca’s aphasia were compared with their healthy matched controls regarding the two different tasks of grammatical judgment and figurine act-out task. The structures used to examine the subjects’ performance included agentive passive, subject cleft, object cleft, object relative clause, and object experiencer psychological verbs.
Results: Our results which supported the trade-off hypothesis, showed that our subjects generally performed better in grammatical judgment task than in figurine act-out task (P≤0.05). Particularly in the second task, as our inner task comparison, the patients’ problems were more severe in object cleft, object experiencer, and object relative clauses: all structures whose interpretations need more cognitive load.
Conclusion: Our findings put more weight on the interactive or constraint-based model of language processing.

Authors: Fereydounnia Sara , Shadmehr Azadeh , Attarbashi Moghadam Behrouz , Talebian Moghadam Saeed , Mir Seyed Mohsen , Salemi Parsa , Pourkazemi Fereshteh
Published: November 2021

Introduction: The present study aimed to investigate the immediate effects of two types of Kinesio taping on the temporal and spatial variables of gait initiation in individuals with and without Functional Ankle Instability (FAI).
Materials and Methods: Thirty semi-professional athletes (15 with and 15 without FAI [control]) were recruited for this study. The gait initiation task was examined before and after the two types of Kinesio taping on a force plate. Temporal (Reaction Phase [RP], Anticipatory Postural Adjustment Phase [APAP]), and spatial variables were recorded and compared between Groups, before and after the tape application.
Results: The results of multiple repeated-measure analyses of variance showed no significant differences for “factor” and “Group by factor” interaction effects for any outcome measure (P>0.05). There were no significant differences for Group effects except for the APAP (F=10.27, P=0.003). The APAA was 71.95 ms longer in the FAI Group (476.95±15.87 ms) compared to the control Group (405.04±15.87 ms).
Conclusion: Kinesio taping application does not influence any of the gait initiation parameters on the force plate. Participants with FAI demonstrated longer APAP which might be due to recurrent injury and instability during sports or physical activity.

Published: November 2021

Introduction: Expressive vocabulary plays a vital role in child language development, and its assessment can be one of the essential indicators to identify language developmental delay, especially in children with Down syndrome. We developed a list of expressive vocabulary and compared the size and class of expressive vocabularies between typically developing and Down syndrome children.
Materials and Methods: Expressive vocabulary of 150 children was examined  in  this study. A total of 120 typically developing Farsi-speaking children (in four age Groups, with   a 6-month interval) and 30 children with Down syndrome (aged 24-48 months) participated in this study. The parents of the children filled out the form that included 636 words from different vocabulary classes. These classes were based on studies that investigated language development in Farsi-speaking children.
Results: The expressive vocabulary size in Farsi-speaking children was significantly higher than in Down syndrome children (P≤0.001). There was no statistically significant difference between boys and girls regarding expressive vocabulary size in two Groups of children. The size of nouns in all age Groups is more than other classes, and the size of conjunctions in all age Groups is less than the other ones. A direct correlation was found between age and the size of expressive vocabulary.
Conclusion: According to the study findings, the list of expressive vocabulary can detect delays in developing expressive vocabulary.

The present study is as an attempt to understand how socio-demographic characteristics (i.e., gender, family socioeconomic status) and school level supports (i.e., school climate, professional guidance at school) influence occupational and educational expectations among rural youth (i.e., aspirations for a meaningful career, future family values, and future employment goals). The findings showed a relationship among the demographic characteristics, school level supports, career aspirations and future family and employment expectations of rural youth. The results of regression analysis indicate that school climate does influence aspirations towards a meaningful career, future family orientation and future employment goals. In addition, aspirations towards a meaningful career are also influenced by gender and professional guidance at school.
Pregled vrednotenj naravoslovnega znanja v prvem vzgojno-izobraževalnem obdobju osnovne šole
Authors: Kožuh Vasja , Plazar Janja
Published: November 2021

This paper presents an overview of Slovenian elementary school evaluation of students’ natural science knowledge in the first three years of elementary school. Science knowledge in Slovenia is not measured regularly; therefore, we have focused primarily on the results of the international TIMSS survey, which measures the mathematical and natural science knowledge of students. The TIMMS survey is performed every four years in various countries, and Slovenia participated from 1995 to 2015. After reviewing and analysing the results of the natural science examinations of Slovenian fourth-graders, we found a steady increase compared to the international average. However, at the same time, the positive attitude towards science lags behind.
Solution of a Linear Nondegenerate Matrix Equation Based on the Zero Divisor
Authors: Zubov N.E. , Ryabchenko V.N.
Published: November 2021

New formulas were obtained to solve the linear non-degenerate matrix equations based on zero divisors of numerical matrices. Two theorems were formulated, and a proof to one of them is provided. It is noted that the proof of the second theorem is similar to the proof of the first one. The proved theorem substantiates new formula in solving the equation equivalent in the sense of the solution uniqueness to the known formulas. Its fundamental difference lies in the following: any explicit matrix inversion or determinant calculation is missing; solution is "based" not on the left, but on the right side of the matrix equation; zero divisor method is used (it was never used in classical formulas for solving a matrix equation); zero divisor calculation is reduced to simple operations of permutating the vector elements on the right-hand side of the matrix equation. Examples are provided of applying the proposed method for solving a nondegenerate matrix equation to the numerical matrix equations. High accuracy of the proposed formulas for solving the matrix equations is demonstrated in comparison with standard solvers used in the MATLAB environment. Similar problems arise in the synthesis of fast and ultrafast iterative solvers of linear matrix equations, as well as in nonparametric identification of abnormal (emergency) modes in complex technical systems, for example, in the power systems
Axisymmetric Turbulent Methane Jet Propagation in a Co-Current Air Flow Under Combustion at a Finite Velocity
Authors: Khujaev I.K. , Hamdamov M.M.
Published: November 2021

The paper introduces a numerical method for solving the problem of the axisymmetric methane jet propagation in an infinite co-current air flow. For modeling, we used the dimensionless equations of the turbulent boundary layer of reacting gases in the Mises coordinates. To close the Reynolds equation, a modified k - ε turbulence model was used. The k - ε model is considered a low Rhine turbulence model. Assuming that the intensities of convective and turbulent transfers of components are the same and using the stoichiometric ratios of the concentrations of components during combustion, we reduced five equations for the transfer and conservation of the mass of components to two equations for the relative excess concentration of the combustible gas. The concentrations of the components were determined from the solutions of these equations. By using relatively excessive velocities and total enthalpy, we reduced the boundary conditions for the three equations to a general form. To solve the problem in the Mises coordinates, we used a two-layer, six-point implicit finite-difference scheme, which provides the second order of accuracy of approximation in coordinates. The equations for the conservation and transfer of substances being non-linear, an iterative process was implemented. The influence of the radius of the fuel nozzle on the indices of the turbulent jet and flame was investigated. Findings of research show that in an endless co-current flow of fuel with a decrease in the radius of the nozzle, the rate of the chemical reaction and the maximum temperature in the calculation area decrease, and the amount of unburned part of the combustible gas increases

Analysis of Allowable Berthing Velocity by Ship Size considering Designed Energy
Authors: Kang Eun-Ji , Lee Hyeong-Tak , Cho Ik-Soon
Published: November 2021

The berthing velocity is the factor that has the greatest influence on the berthing energy. For the vessel to berth safely, it should not exceed the appropriate berthing velocity. In addition, when the vessel is berthing, it should be berthed with berthing energy smaller than the energy absorption of the fender. This study intends to derive the allowable berthing velocity by ship size considering the berthing capacity. When a small vessel berth, the allowable berthing velocity is greater than when a relatively large vessel berths. In this study, the extrapolated velocity is defined as the relative value of the ship’s berthing velocity when considering the ship's size and the berthing capacity. A regression equation for the allowable berthing velocity by ship size was derived by calculating the designed berthing energy for each fender performance. It was also verified whether any ships were exceeding the allowable berthing velocity by comparing it with the measured data for each jetty. In addition, the extrapolated velocity was proposed using the regression equation, and as a result of applying the measured data, 11 ships exceeded the designed velocity in jetty 1, but it was confirmed that all ships were safely berthed in jetty 2,3. Therefore, the target pier of this study was evaluated as a pier where ships can be berthed safely. A safer berthing velocity operation guideline can be suggested if the allowable berthing velocity by ship size is analyzed and utilized at various piers. Extrapolated velocity can also be used for risk analysis of berthing.

Published: November 2021

Dental pulp tissue engineering (TE) quests to regenerate dentin/pulp complex by combining a suitable supporting matrix, stem cells, and biochemical stimuli. Such procedures foresee a matrix that can be easily introduced into the root canal system (RCS) and tightly adhere to dentin walls to assure the dentin surface's proper colonization with progenitor cells capable of restoring the dentin/pulp complex. Herein was investigated an injectable self-setting hyaluronic acid-based (HA) hydrogel system, formed by aldehyde-modified (a-HA) with hydrazide-modified (ADH), enriched with platelet lysate (PL), for endodontic regeneration. The hydrogels' working (wT) and setting (sT) times, the adhesion to the dentine walls, the hydrogel's microstructure, and the delivery of human Dental Pulp Cells (DPCs) were studied in vitro. Hydrogels incorporating PL showed a suitable wT and sT and a porous microstructure. The tensile tests showed that the breaking point occurs after 4.13 mm deformation. While in the indentation test after 1.3 mm deformation. Both breaking points occur in the hydrogel extension. The HA/PL hydrogels exhibited supportive properties and promoted cell migration toward dentin surfaces in vitro. Overall, these results support using PL-laden HA injectable hydrogels (HA/PL) as a biomaterial for DPCs encapsulation, thereby displaying great clinical potential towards endodontic regenerative therapies.
Water Quality of the Seyfe Lake Basin, Turkey
Authors: Kıymaz Sultan , Bleam William
Published: November 2021

Seyfe Lake is an important part of the natural ecosystem of Central Anatolia and lies within a 1487 km2 closed basin. Groundwater withdrawal for irrigation and recent climatic change have caused lake area to decrease for decades and to completely disappear briefly in August 2008. Groundwater quality is crucial for sustainable irrigation in the Seyfe Basin. A key finding of this study is the difference in the Hardie-Eugster alkalinity-to-calcium ratio of the lake water and that of most groundwater wells in the basin. This difference in the chemical signature of Seyfe Lake and basin groundwater means the evaporative salinization pathway of most groundwater discharged into the lake cannot account for the composition of Seyfe Lake. The ratio of actual evapotranspiration to precipitation will increase under current climate change projections. A second finding, with implications for soil salinization, is that most groundwater in Seyfe Basin has a Hardie-Eugster alkalinity-tocalcium ratio greater than unity, meaning soil alkalization will accompany soil salinization.

Central Bureau of Statistics reports that the population in Indonesia continues to increase every 10 years. The more the population swells, the greater the need for food. To meet the community's need for food availability, there are several agricultural obstacles such as growth criteria that are not by the type of commodity. Air temperature, humidity and intensity of water supply are included as criteria for plant growth (Budiman and Saraswati, 2005). Erratic weather changes make farmers unable to guarantee production results with good quality, and quantity. This research is designed using a tool that has been integrated with the Internet of Things system embedded in a raspberry pi as the overall processing core [1]. In addition to the raspberry pi, there are also several sensors as real condition readings, several relays as an electric pump controller and a solenoid valve as an electrical faucet controller, and these components will be connectedwith the ESP8266/NodeMcu module using a wifi connection. The data read by these sensors is displayed on the smartphone screen as a monitoring function in real-time and also the user can directly take action using the remote control, both automatic actions using machine learning or manual action.This sophisticated screenhouse can perform irrigation actions and temperature regulation automatically without having to do direct monitoring every time. The use of this system in agriculture allows the owner to not need to do direct monitoring by coming to the screenhouse, users can simply monitor using a smartphone connected to the Internet network.The application of this system can carry out watering actions and regulate the temperature in the screenhouse room automatically according to the aspects of good growth criteria for plants.

In 2020, the US Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory, provided technical oversight during a navigation study to assist the Galveston District evaluation of different channel widening alternatives for larger ships transiting the Houston Ship Channel (HSC), Texas. The widening proposals encompassed several areas of the HSC including the Bay Section, the Bayport Ship Channel, Barbours Cut Channel, and the Bayou Section. The study was performed at the San Jacinto College Maritime Technology and Training Center (SJCMTTC) Ship/Tug Simulator (STS) Facility in La Porte, TX. The SJCMTTC STS is a real-time simulator; therefore, events on the simulator happen at the same time rate as real life. A variety of environmental forces act upon the ship during the simulation transit. These include currents, wind, waves, bathymetry, and ship-to-ship interaction. Online simulations of the project were conducted at SJCMTTC over a 3-week period – May through June 2020. Several mariners including Houston Pilots and G&H tugboat Captains participated in the testing and validation exercises. ERDC oversight was performed remotely because of the COVID-19 pandemic. Results in the form of engineering observations, track plots, and pilot interviews were reviewed to develop final conclusions and recommendations regarding the final design.

Active compressional tectonics along the outer front of the Apenninic-Maghrebian chain (Italy) is well documented along the northern and central segments and in Sicily. On the other hand, the Southern Apenninic Outer Front (SAOF) orogenic activity is well established only until the Lower-Middle Pleistocene. We address the hypothesis of its subsequent late Quaternary activity in central-southern Italy (Abruzzo and Molise regions). We integrated topographic and fluvial network analyses along with morphotectonic investigation of fluvial terraces to identify evidence of differential rock uplift. We compared the results with the main geolithological units, known structural elements, and long-term deformation history from seismic line interpretation. We found variable evidence suggesting localized rock uplift in the Abruzzo region along the SAOF (Abruzzo Citeriore Basal Thrust segment) and inward structures on its hanging wall (Casoli-Bomba high), as well as along part of the Struttura Costiera thrust. Middle-to-Late Pleistocene deformation is constrained by terrace tilting and disruption along the Pescara river. Localized shortening along segments of the Apenninic Outer Front could explain the observed pattern of anomalies which is difficult to explain with long-wavelength regional uplift alone. Our reconstruction is consistent with the long-term deformation of the area and agrees with its seismotectonic setting. Despite the low deformation rate context and the peculiar geological setting which challenges the interpretation of the topographic and geomorphic signals, this study compels reconsideration, in terms of seismic hazard assessment, of the existence of late Quaternary active thrusting in central-southern Italy.

Background

Red blood cell distribution width (RDW) and the platelet-to-lymphocyte ratio (PLR) are associated with different types of prognoses in critically ill patients. But, the value of RDW and PLR in predicting the occurrence of acute kidney injury (AKI) in critically ill patients are unknown. The purpose of the study was to explore the associations of RDW and PLR with AKI incidence.
Methods

Among 1500 adult patients in the intensive care unit (ICU) between January 2016 and December 2019 were enrolled, we examined the associations of baseline RDW and PLR with the risk of AKI development using logistical analysis. In addition, we explored the value of RDW and PLR in predicting in-hospital mortality.
Results

The study participants included 951 men and 549 women, aged 60.1±16.14 years. The subjects had a mean RDW of 14.65±2.14% and a mean PLR of 188.16±129.2. Overall, 615 (41%) patients were diagnosed with AKI. There were remarkable differences in RDW and the PLR between the AKI and non-AKI groups (P<0.001). After adjustment, the association of RDW with AKI development risk strengthened (OR: 1.28, 95% CI: 1.19-1.36). Moreover, we divided the groups into two subgroups each; the high-RDW (≥14.045%) group had a high risk of developing AKI (OR=5.189, 95% CI: 4.088-6.588), while the high-PLR(≥172.067)group had a risk of developing AKI (OR=9.11,95% CI:7.09-11.71). The areas under the receiver operating characteristic curves (AUCs) for the prediction of AKI incidence based on RDW and PLR were 0.780 (95% CI: 0.755-0.804) and 0.728 (95% CI:0.702-0.754) (all P< 0.001), with cut-off values of 14.045 and 172.067, respectively. Moreover, a higher RDW was associated with a higher rate of hospital mortality (OR: 2.907, 2.190-3.858), and the risk of in-hospital mortality related to PLR was 1.534 (95%CI: 1.179-1.995). The AUC for in-hospital mortality based on RDW was 0.663 (95%CI:0.628-0.698), while the AUC for in-hospital mortality based on the PLR was 0.552 (0.514-0.589).
Conclusions

A higher RDW related to a higher risk of the occurrence of AKI and in-hospital mortality in ICU.The PLR also showed predictive value for the occurrence of AKI but did not show any clear prediction value of in-hospital mortality.

BackgroundSNRPC is cloned on human chromosome 6p21.31, which encodes a special protein component of U1 snRNP granules. Although SNRPC played an important role in the pre-mRNA splicing starting and adjustment, but in the tumor biological function is still unknown.MethodThrough the pan-cancer analysis of SNRPC, and our data sets, phosphorylation and functional network analysis based on TCGA (Cancer Genome Map) and GEO (Integrated Gene Expression Database), also from the western blot, qRT-PCR and CCK-8, cloning-forming experiment, scratch experiment to prove SNRPC biological function.ResultsSNRPC is related to the regulation of RNA, shear, and protease signals and has an important effect on ovarian cancer prognosis. Through a series of biological information data mining and basic experiments, we found that SNRPC plays an important role in the proliferation and migration of ovarian cancer. SNRPC expression is positively correlated with the immersion of CD4+T cells, macrophages, and neutrophils (p< 0.05), as obtained through the TIMER database (Tumor Immunological Assessment Resources) database. ConclusionOur pan-cancer research provides SNRPC in different tumors, especially the relatively comprehensive understanding of the carcinogenic potential of ovarian cancer.

Background: The COVID-19 pandemic presented severe challenges to emergency practice of acute coronary syndrome (ACS). However, poor evidence was shown on ACS in a non-hot-spot region. We sought to clarify the influence of the first-wave COVID-19 pandemic on emergency ACS from a non-epicenter region.Methods: This retrospective multicenter study was conducted in emergency ACS patients during the pandemic (from 2020-01-23 to 2020-03-29) and the ones during the same period in 2019. Clinical characteristics, timeline parameters and treatment strategies were compared between different groups. Association of the pandemic with non-invasive therapy was further assessed.Results: Compared with 2019, ACS had a drop in admission (267 cases vs. 475 cases) and invasive therapy (140 cases vs. 318 cases). Also, process delays were detected including the period from symptom onset to first medical contact (S-to-FMC, 5h vs. 2.5h), the period from FMC to electrocardiogram (ECG) completed (8min vs. 4min) and the period from FMC to dual antiplatelet therapy (FMC-to-DAPT, 25min vs. 19min). Primary percutaneous coronary intervention (PPCI) decreased by 54.9% in STEMI and early invasive therapy decreased by 59.2% in NSTE-ACS. The proportion of invasive therapy in NSTE-ACS decreased more than in STEMI (16.9% vs. 10.1%) with longer process delay. The pandemic was associated with increased non-PPCI in STEMI (OR=1.707, 95%CI 1.082-2.692, P=0.021) and elevated medication in NSTE-ACS (OR=2.029, 95%CI 1.268-3.247, P=0.003), respectively. Conclusion: Even in a non-epicenter region, the first-wave COVID-19 pandemic caused a significant reduction of invasive therapy and evident process delays in emergency ACS.
