Smart Farming Platform Using IoT and UAVs

With the advancement of communication technology, many innovative applications have developed in agriculture as a result of the integration of the Internet of Things (IoT) with unmanned aerial vehicles (UAVs), leading to the modernization of agriculture. This study seeks to propose an effective and low-cost platform for comprehensive monitoring of environmental parameters using IoT and drones.The preparation of this paper was based on a platform that was tested in a realistic environment on a farm near the city of Al-Median in Tunisia, where the platform was built to suit the realistic environment of a farm in Baghdad, through the use of sensors above and below the ground, which meets the experimental work and standards for automated and real-time monitoring. For environmental standards, the unified theory of acceptance and use of technology model was used, which is a model based on four basic elements: 1) expected performance, 2) expected effort, 3) social impact, and 4) facilitating conditions for obtaining results. The unique integration of IoT sensors with drones has shown impressive experimental results, indicating the possibility of performing both automatic and manual actions by humans. These smart moves contribute significantly to promoting precision agriculture, leading to a significant increase in agricultural production and conservation of natural resources

Non-Aggressive Treatment in Knee Osteoarthritis Patients: A Literature Review

Introduction: High prevalence of knee osteoarthritis (OA) in Iran and the subsequent disability have resulted in representing multifarious non-aggressive interventions with distinct influences on the disease. The aim of this study was to review previous domestic studies about the effects of conservative therapeutic options on patients with knee OA. Materials and Methods: Using search engines involving IranMedex, MedLib, ISC, Google Scholar, Magiran, SID, rehabilitation, and medical journals based on defined keywords, 98 Persian language articles were found, and 37 studies were finally included in our study after applying the exclusion criteria. The type of study, the pattern of choosing subjects, patient information, the measurements, interventions, and the results were exploited from each article, and the physiotherapy evidence database (PEDro) scale was administrated to evaluate the studies. Results: Based on analysis of PEDro scale results (Mean±SD for articles score: 5.89±1.29), the quality of most articles was as fair and good. The focus of conservative treatments was on exercise therapy methods, assistive devices, and physical therapy management. From a clinical perspective, the evidence indicates the appropriate effects of such treatment choices on alleviating pain, enhancing function, and improving quality of life in individuals with knee OA. Conclusion: Most conservative methods can reduce pain, and improve quality of life and physical performance in patients with knee OA. However, further high-quality studies with larger sample sizes and long-term follow-ups are required to determine whether knee OA can be managed by conservative methods

New 5-bromo-2-hydroxybenzaldehyde S-ethylisothiosemicarbazone and its mixed-ligand Cu(II) complex with imidazole: synthesis, characterization and DFT calculation

Abstract A new Schiff base ligand of 5-bromo-2-hydroxybenzaldehyde S-ethyl-isothiosemicarbazone (H2L) was synthesized and its mixed-ligand Cu(II) complex was also prepared by reaction of Cu(NO3)2·3H2O with H2L and imidazole. Their structures were fully characterized by elemental analysis, FT-IR, molar conductivity and UV-Vis methods. The analytical data suggest that the metal, H2L and imidazole ratios in the Schiff base complex are 1:1:1. Single crystal diffraction was also used to better understand the molecular structure of the Cu(II) complex. The results of physico-chemical analyses of the Schiff base complex reveal the coordination geometry around the central atom is square planar. The H2L ligand (NNO donor) is coordinated to the metal center as a tridentate bionegatively agent. Another position of the square planar geometry is occupied by the imidazole ligand. Furthermore, computational studies of the new complex were performed by carrying out DFT calculations. Geometry optimization and natural band analysis of the complex is discussed in further detail

Case report: A boy with previous history of NS was admitted with headache and decrease of level of consciousness and his brain images were revealed hemorrhagic thrombosis Conclusions: Cerebral vein thrombosis must be considered in patients with history of NS (especially in new cases and during of relapses) and prevention of hemoconcentration is very important to decrease thrombosis risk

A Novel Scalable Reconfiguration Model for the Postdisaster Network Connectivity of Resilient Power Distribution Systems

The resilient operation of power distribution networks requires efficient optimization models to enable situational awareness. One of the pivotal tools to enhance resilience is a network reconfiguration to ensure secure and reliable energy delivery while minimizing the number of disconnected loads in outage conditions. Power outages are caused by natural hazards, e.g., hurricanes, or system malfunction, e.g., line failure due to aging. In this paper, we first propose a distribution-network optimal power flow formulation (DOPF) and define a new resilience evaluation indicator, the demand satisfaction rate (DSR). DSR is the rate of satisfied load demand in the reconfigured network over the load demand satisfied in the DOPF. Then, we propose a novel model to efficiently find the optimal network reconfiguration by deploying sectionalizing switches during line outages that maximize resilience indicators. Moreover, we analyze a multiobjective scenario to maximize the DSR and minimize the number of utilized sectionalizing switches, which provides an efficient reconfiguration model preventing additional costs associated with closing unutilized sectionalizing switches. We tested our model on a virtually generated 33-bus distribution network and a real 234-bus power distribution network, demonstrating how using the sectionalizing switches can increase power accessibility in outage conditions

Accuracy of Cone-Beam Computed Tomography in Determining the Root Canal Morphology of Mandibular First Molars

Introduction: The aim of the present in vitro study was to compare the accuracy of cone-beam computed tomography (CBCT) in determining root canal morphology of mandibular first molars in comparison with staining and clearing technique. Methods and Materials: CBCT images were taken from 96 extracted human mandibular first molars and the teeth were then evaluated based on Vertucci’s classification to determine the root canal morphology. Afterwards, access cavities were prepared and India ink was injected into the canals with an insulin syringe. The teeth were demineralized with 5% nitric acid. Finally, the cleared teeth were evaluated under a magnifying glass at 5× magnification to determine the root canal morphology. Data were analyzed using the SPSS software. The Fisher’s exact test assessed the differences between the mesial and distal canals and the Cohen’s kappa test was used to assess the level of agreement between the methods. Statistical significance was defined at 0.05. Results: The Kappa coefficient for agreement between the two methods evaluating canal types was 0.346 (95% CI: 0.247-0.445), which is considered a fair level of agreement based on classification of Koch and Landis. The agreement between CBCT and Vertucci’s classification was 52.6% (95% CI: 45.54-59.66%), with a significantly higher agreement rate in the mesial canals (28.1%) compared to the distal canals (77.1%) (P<0.001). Conclusion: Under the limitations of this study, clearing technique was more accurate than CBCT in providing accurate picture of the root canal anatomy of mandibular first molars.Keywords: Cone-Beam Computed Tomography; Root Canal Morphology; Root Clearin

Effect of the FIFA 11+ Programme on Vertical Jump Performance in Elite Male Youth Soccer Players

Despite the success of the FIFA 11+ programme in preventing injury, convincing coaches and players to do these exercises is diffi cult only in order to prevent injury, unless the programme can be shown to have a positive and direct impact on the performance. Th is study aims to investigate the eff ect of the FIFA 11+ programme on vertical jump performance in male elite-youth soccer players. Twenty-four male soccer players (mean ± SD: age = 16.79 ± 1.18 years, height = 174.17 ± 8.12 cm, mass = 62.45 ± 10.01 kg, experience = 6.96 ± 1.26 years) participated in this study and were randomly divided equally into two groups, FIFA 11+ and control. Th e experimental group performed the FIFA 11+ programme three times per week for eight weeks whereas the control group just performed their regular warm-up programme. Th e mixed-repeated measures ANOVA showed that there was a signifi cant improvement in the vertical jump performance between groups in post-test (P=0.002) while no signifi cant improvement was found between groups aft er 1-month of stopping the FIFA 11+ programme (P=0.076). It can be concluded that performing the eight-week FIFA 11+ programme can enhance the jump height in male elite youth soccer players. It seems that the FIFA 11+ programme could be incorporated into regular soccer practice as a warm-up programme instead of a conventional warm-up programme. However, due to the failure to maintain the long-term eff ectiveness of the FIFA 11+ programme on the jump height of soccer players, the continuation of performing this programme is necessar
