Residual Dentin Thickness in Bifurcated Maxillary Premolars after Cervical Preflaring Preparation: A CBCT Analysis

This study evaluated the residual dentin thickness (RDT) of maxillary premolars after the use of different cervical preflaring (PF) drills by using cone-beam computed tomography (CBCT). Eighty bifurcated maxillary premolars were accessed and randomly divided into 5 groups (n=16). PF was performed with Gates-Glidden #1, #2, and #3 (group 1), Largo #1 and #2 (group 2), and LA Axxess #20/. 06 (group 3), #35/. 06 (group 4), and #45/. 06 (group 5). CBCT images were acquired before (preoperative) and after (postoperative) PF. Initial and final cervical dentin thickness was measured at the buccal, palatal, mesial, and distal aspects, 0.5 mm coronally to the furcation, on both buccal and palatal roots, using CBCT’s image analysis software. The percentage of removed dentin after PF preparation was also calculated. Data were analyzed using ANOVA followed by Tukey’s test at a significance level of P < 0.05. No statistically significant differences were found among the groups for preoperative or postoperative RDT (P > 0.05). LA Axxess #20/. 06 (group 3) removed significantly less cervical dentin at all root canal aspects on both buccal and palatal roots. The mesial aspect of the buccal root and distal aspect of the palatal root were significantly reduced after the use of LA Axxess #45/. 06 (group 5) and Largo #1 and #2 drills (group 2), respectively (P < 0.05). PF in bifurcated maxillary premolars should be performed with LA Axxess instrument #20/. 06. The use of Gates-Glidden #1, #2, and #3, Largo #1 and #2, and LA Axxess #45/. 06 drills should be done with caution.
The Influence of Different Seeding Application Rates and Sowing Time on Maize Hybrids’ Productivity in the Conditions of the Republic of Bashkortostan’s Southern Forest-Steppe Zone

Maize takes the leading place in yield and is one of the most common crops in the world. Selection of the optimal seeding application rate and time is among the central issues in maize cultivation technology and is highly relevant. The research made in 2018–2020 aimed at improving the maize technology block for grain (seeding application rate and sowing time, southern forest-steppe, the Republic of Bashkortostan). For this purpose, a field experiment was launched in a fourfold replication. The experimental design included hybrids: Nur, Mashuk 171, Baikal and Mashuk 220 with a planting density of 60 (control), 70, 80, and 90 thousand pcs/ha. The experiment revealed a high correlation dependence of the yield of green mass and grain on the sowing time (r = 0.876–0.915 and r = 0.951–0.963). In the conditions of the Republic of Bashkortostan’s southern forest-steppe, Baikal and Mashuk 171 hybrids are recommended to be used for animals and poultry diets and the planning of maize cultivation technological schemes at early sowing time (May 10) and a seeding application rate of 80 thousand pcs/ha. The results of the research apply to the formation of agricultural feeding diets.
Integrating Life Skills through Physical Activities Programs

The purpose of this study was to investigate the integration of life skills through physical activities programs on the improvement of student life skills. The population of this study was 64 college students in Indonesia divided into two groups (experimental group n = 34 and control group n = 30). The sampling technique used cluster random sampling. The research method used was a quasi-experiment with a pre-test post-test control group design. The instrument used was the life skills scale for sport adaptation (LSSS) which consists of eight components, namely teamwork, goal setting, time management, emotional skills, communication, social skills, leadership, problem-solving, and decision making. The results showed that the physical activity integrated with the life skill program had a more significant impact on the improvement of the student's life skills than the physical activity without the integration of the life skill program. Further findings revealed that the social skill component was the life skill component that gained the highest increase. It shows that the integration of life skill programs in physical activities provides better results than physical activities without the integration of life skills programs.
PERCUTANEOUS ULTRASOUND GUIDED DRAINAGE COMPARED WITH CONVENTIONAL INCISION AND DRAINAGE

Objectives: The aim of this study was to compare the management of puerperal breast abscess by ultrasound guided percutaneous drainage v/s incision and drainage with special attention to resolution time and complications. Setting: Allied Hospital Faisalabad. Period: Jan 2005June 2007. Patients and Methods: 60 patients with puerperal breast abscess were studied. Patients were divided into two groups randomly after informed consent. In Group A; patients were treated with percutaneous drainage under local anesthesia while Group B patients were treated by conventional incision and drainage, and results were compared with reference to resolution time and complications rate using student’s t-test. Results: By percutaneous method abscess healed in 5-8 days time. Recurrent abscess was found in one case (3%), milk fistula formation in one case (3%) and no residual abscess was found. There was no scar formation, induration or distortion of the breast parenchyma. Breast-feeding was interrupted in four patients (13%) only due to milk fistula (one case), recurrent abscess (one case) and patient’s own preference (two cases). On the other hand by conventional method healing took 15-25 days with pain and discomfort of daily dressings, scarring and cessation of breast feeding in most of the cases. Conclusion: Percutaneous ultrasound guided placement of suction drainage catheter in puerperal breast abscess for 5-8 days is less invasive, high resolution rate, scarless, low complication rate and preserves the function of breast-feeding as compared to conventional incision and drainage.
Influences of True Triaxial Loading-Unloading Stress Paths on Mechanical Properties and Wave Velocity of Coal Samples subject to Risk of Rock Burst

To study fracture evolution and peak stress in burst risk coal samples (BRCSs) under true triaxial loading and unloading conditions, experimental and numerical research was applied to BRCSs under true triaxial stress paths entailing “x-direction displacement fixed, y-direction loading, z-direction unloading. ” Both the experimental and the numerical results demonstrated that the peak stress borne by the BRCSs was not only affected by the initial stress but also had a negative exponential relationship with the ratio of the unloading rate and the loading rate (RURLR); therefore, peak stress equations of BRCSs under true triaxial loading and unloading conditions were established. The triaxial stress-time curves obtained by experiments and simulations exhibited an “elasticity-yield-destruction” phase, and the characteristics of the yield phase were determined by the RURLR. A typical BRCS was selected for velocity tomographic imaging to analyze the fracture evolution characteristics under true triaxial loading and unloading. The results showed that when the BRCS was subjected to a triaxial state of stress, the high- and low-velocity regions existed alternately due to the presence of the crack; during the elastic phase, the crack closed during loading in the previous phase was reopened upon unloading, so that the velocity of the sample decreased and a wide range of low-velocity regions could be formed; when entering the yield phase, the original crack continued to expand into a hole-through crack, leading to wider extreme values and ranges of these low- and high-velocity regions; at the breaking phase, multiple microcracks were generated around the hole-through cracks, decreasing the overall velocity, and showing point distributions characteristics of high- and low-velocity regions. Overall, many low-velocity regions with similar normal directions to the unloading direction were formed; these correlated well with macrofractures (postfailure).
Assessment of Myocardial Salvage Index after Primary Percutaneous Intervention of ST Elevation Myocardial Infarction Patients Using Myocardial Magnetic Resonance Imaging Techniques

Objectives: The aim of this work was assessment of myocardial salvage using various magnetic resonance imaging techniques immediately after primary percutaneous coronary intervention of ST elevation myocardial infarction patients and at midterm follow up. Methods: The current study was conducted on 30 patients referred to Aswan heart center or Cardiology department, Tanta University hospital with a diagnosis of ST elevation myocardial infarction during the period from august2017 to December 2017. All patients were subjected to history taking ,clinical assessment ,12 lead ECG, Laboratory biomarkers including cardiac enzyme biomarkers, complete blood count, liver function test, renal function test and lipid profile primary then primary percutaneous coronary intervention was done then cardiac magnetic resonance imaging within 3 days and after 3 months including the following sequences: Steady-state free precession, T2 weighted triple inversion recovery sequence and Early and late gadolinium enhancement to measure the area at risk and myocardial salvage index. Results: Myocardial salvage index was found to improve with improving thrombolysis in myocardial infarction (TIMI) flow post intervention (p value=0.004), also the presence of microvascular obstruction (p value =0.034) and intramyocardial hemorrhage (p value=0.014) had a negative impact on myocardial salvage index. Peak cardiac enzyme biomarkers (troponin p value=0.001,CK p value=0.005,CKMB p value=0.002) were also associated with increased area at risk however did not affect the myocardial salvage index. Conclusion: Proper management of the occluded coronary artery is a corner stone in improving myocardial salvage index which can be properly assessed with cardiac MRI.
Synthesis and Characterization of Hydroxyapatite- (HAP-) Clay Composites and Adsorption Studies on Methylene Blue for Water Treatment

Dyes used by the textile, tannery, and food industries tend to pollute water bodies and must be removed to get clean water. Hydroxyapatite (HAP) was synthesized from eggshells using the wet precipitation process. The as-synthesized HAP was characterized using Fourier Transform Infrared (FTIR) and X-ray powder diffraction (XRD). The synthesized HAP was mixed with three different clays: halloysite (HNT), kaolinite (KAO), and bentonite (BENT). The removal efficiency values of methylene blue (MB) from the data showed that HAP-BENT adsorbents had higher values, followed by HAP-HNT and then HAP-KAO adsorbents. The combined masses of 24 mg, 34.5 mg, and 33 mg (representing 20%, 15%, and 10% of HAP-BENT mass) had average adsorption capacity values of 20.7 mg/g, 17.2 mg/g, and 17.9 mg/g, respectively. For each mass percentage, the adsorption capacity values were found to decrease with adsorbent dosage. The HAP-BENT composites had removal efficiency values of 98.4, 91.9%, and 91.9%, respectively. Adsorption data for the HAP-BENT adsorbents were found to be well described by the Langmuir isotherm model and pseudo-second-order kinetic model. The effect of temperature on adsorption capacity was evaluated and thermodynamical modeling was undertaken. The thermodynamical modeling predicts that based on the value of the change in enthalpy and Gibbs free energy the process was exothermic and spontaneous. This work confirms the potential of HAP-clay composites in removing MB from water.
Endocrine, energy, and lipid status during parturition and early lactation in indigenous goats native to the Algerian Sahara

Abstract Background and Aim: Goats are widely distributed in southwest Algeria. The Saharan goat is perfectly adapted to the harsh conditions of arid areas, and it is characterized by resistance to long photoperiod and reduced metabolic needs, allowing the survival of its offspring by maintaining lactation. Several studies have demonstrated that parturition and lactation are critical periods that induce hormone, energy, and lipid status changes in mammals. However, the relationship between the blood biochemical parameters of parturition control and lactation functions in the Algerian Saharan goat has not been thoroughly documented. Therefore, this study assesses hormone and metabolite levels during parturition and early lactation in Saharan goats reared in arid areas. Materials and Methods: Experiments were performed on 14 multiparous female goats, and blood samples were collected during parturition, 4 days postpartum (D1PP-D4PP), and during the first 12 weeks of lactation (W1-W12) to analyze prolactin, cortisol, glucose (GLU), total proteins (TP), cholesterol (CHO), triglycerides (TGs), total lipids (TL), low-density lipoproteins (LDLs), high-density lipoproteins (HDLs), and very LDLs (VLDLs). Results: Statistical data analysis revealed a significant (p<0.05) increase in plasma prolactin concentrations at W1 after parturition, reaching maximum values at W3 and W9, and remained high until W12 of lactation. Plasma cortisol levels were high at parturition, reaching two peaks at W3 and W9, and then decreased at W5, W7, and W12 of lactation. No significant changes were found in serum GLU levels during the first 7 weeks of lactation compared with parturition day; then, the levels became significantly (p<0.05) lower at W8, W11, and W12 of lactation. Plasma TP increased significantly (p<0.05) at D3PP, W1, and W4, then decreased significantly (p<0.05) at W8. In addition, this decrease coincided with that of GLU production. Serum CHO, TGs, TL, LDLs, and VLDLs, were low at parturition and high at D4PP and during the first 3 months of lactation. Furthermore, HDL levels were low at D3PP, 1st, and 3rd months and high at the 2nd month of lactation. Conclusion: This study emphasized the impact of parturition and the 1st weeks of lactation on endocrine and metabolic changes in indigenous goats living in the Algerian Sahara Desert. These results can be used to monitor and improve farming management and understand physiological adaptive strategies, mainly lactation function sustainability, of this goat living in marginal zones.
Experimental and Theoretical Analysis of Cracking Moment of Concrete Beams Reinforced with Hybrid Fiber Reinforced Polymer and Steel Rebars

This study aims at experimentally and theoretically investigating the cracking moment (Mcrc) of hybrid Fiber Reinforced Polymer (FRP)/steel Reinforced Concrete (RC) beams. Six hybrid Glass FRP (GFRP)/steel and three GFRP RC beams with various GFRP and steel reinforcement ratios are tested in four-point bending scheme. Experimental results indicate that both GFRP and steel rebars affect Mcrc, but the effect of steel reinforcement is more significant. When the steel reinforcement ratio increases to 1.17%, Mcrc goes up to 15.9%, while the same value for GFRP is only 9.7%. An analytical method is proposed based on the plain section assumption and nonlinear behavior of materials for estimating Mcrc. The proposed model shows a good agreement with the experimental data conducted in this study and collected from the literature. The results of the parametric study give evidence of the positive effects of hybrid reinforcement ratios and elastic modulus of FRP on Mcrc of hybrid RC beams.
Spread beyond the border: Small Scale genetic structure of the introduced Banggai cardinalfish (Pterapogon kauderni) population in the Bali Strait

The living marine aquarium trade has been known to mediate various aquatic invaders to spread and established a new population outside of their natural home range. In most cases, the introduce species cause a cascaded effect which harm the native species and their ecosystem. The successful of the invasion event often related to the genetic properties of the introduced species. Therefore, using a molecular approach based on a mitochondrial DNA marker, the present work aimed to evaluate the population genetic structure of the introduced P. kauderni population in Bali Strait. Samples were collected from four sites in Gilimanuk Bay, Bali Strait. Our results showed a high haplotype diversity and low nucleotide diversity that might be a signal of a bottleneck. Overall, we found five haplotypes comprising two unique haplotypes and three shared haplotypes. Genetic structure was detected in some localities, which indicates Pterapogon kauderni might originated from various genetically distinct populations. However, we could not conclusively determine the observed patterns of the genetic structure within each site. These patterns are likely related to the multiple introduction event of P. kauderni in Bali Strait. Additional samples from both side (introduced and native habitat) combined with more rapidly evolving markers may describe the structure more clearly.

This study was aimed at development of natural polymer-based mucoadhesive bilayer films loaded with moxifloxacin hydrochloride (Mox) and clove essential oil (CEO) to potentially combat bacterial infection associated with periodontitis. Methods: Films were synthesized by double solvent casting technique having an antibiotic in the gellan gum-based primary layer with clove oil in a hydroxyethyl cellulose-based secondary layer. Results: Prepared films were transparent, flexible, and showed high antibacterial response against both gram-positive and gram-negative bacteria. The films showed excellent pharmaceutical attributes in terms of drug content, folding endurance, swelling index, and mucoadhesive strength. Solid state characterization of formulation showed successful incorporation of drug and oil in separate layers of hydrogel structure. An in-vitro release study showed an initial burst release of drug followed by sustained release for up to 48 hours. Conclusion: The prepared mucoadhesive bilayer buccal films could be used as a potential therapeutic option for the management of periodontitis.

Machine learning deployment for arms dynamics pattern recognition in Southeast Asia region

Finding the most significant determinant variable of arms dynamic is highly required due to strategic policies formulations and power mapping for academics and policy makers. Machine learning is still new or underdiscussed among the study of politics and international relations. Existing literature have much focus on using advanced quantitative methods by applying various types of regression analysis. This study analyzed the arms dynamic in Southeast Asia countries along with its some strategic partners such as United States, China, Russia, South Korea, and Japan by using ‘Decision Tree’ of machine learning algorithm. This study conducted a machine learning analysis on 55 variable items which is classified into 8 classes of variables videlicet defense budget, arms trade exports, arms trade imports, political posture, economic posture, security posture and defense priority, national capability, and direct contact,. The results suggest three findings: (1) state who perceives maritime as strategic drivers and forces will seek more power for its maritime defense posture which is translated to defense budget, (2) big size countries tend to be an arms exporter country, and (3) state’s energy dependence often leads to a higher volume of arms transfers between countries.
Addressing up-scaling methodologies for convection-permitting EPSs using statistical and machine learning tools

Abstract. Convection-permitting weather forecasting models allow for prediction of rainfall events with increasing levels of detail. However, the high resolutions used can create problems and introduce the so-called “double penalty” problem when attempting to verify the forecast accuracy. Post-processing within an ensemble prediction system can help to overcome these issues. In this paper, two new up-scaling algorithms based on Machine Learning and Statistical approaches are proposed and tested. The aim of these tools is to enhance the skill and value of the forecasts and to provide a better tool for forecasters to predict severe weather.
Collapse Probability of Immediate and Special Moment Frames in Tehran under MCE

Residential buildings in most cities, which make up the most significant percentage of buildings, generally contain the most financial and human losses in the face of strong earthquakes. The purpose of this study is to investigate the possibility of the collapse of intermediate and unique steel moment frames against maximum ground excitations. In this study, through the first two steps of PEER methodology, using four steel structural frames with intermediate and unique moment frames, after designing according to the codes of national building regulations of Iran and standard 2800, this probabilistic evaluation was used to ensure their safety against collapse. In the next step, to deepen the results, 7 other sites from Tehran were selected. Their hazard spectrum was used to calculate the probability of collapse. In the end, it was observed that, with the reduction of the number of structural floors, the IDA curves at the lower IM level become horizontal in this project. The results showed that some of the 5-story steel structures under study in some parts of Tehran have a higher probability of collapse than acceptable.
