Clival fracture is a rare traumatic injury that usually occurs in patients with high-energy trauma to the head and neck. Here, we present and discuss our experience with a patient with a transverse clival fracture associated with a significant vertical displacement.A 52 years-old comatose patient was admitted to our emergency department after a high-energy motor vehicle accident. The physical examination demonstrated a Glasgow coma scale (GCS) of 6 (with the motor scale of 4) associated with a left-sided six cranial nerve palsy, a left-sided fixed and dilated pupil; and quadriparesis that was more severe on the right side. The imaging tests revealed the brain contusions, pneumocephalus, and generalized brain edema without local mass effect and midline shift. Also, it showed TCF with a significant vertical displacement and a signal change within the medulla oblongata. The clival fracture was managed in a mild head flexion position without bracing, a routine ICU exchange body positioning program, and the minimum time of supine positioning. The follow-up imaging three months later showed complete bone fusion without any displacement. After 18 months of follow-up, he ambulated, and cranial nerve deficits improved except for mild diplopia due to a remnant of 6 nerve paresis.Transverse clival fracture, as most of the authors reported, does not need surgical treatment. Bracing can be used in conscious ambulated patients. A mild head-on-neck flexion position associated with suppurative care for bedsores can be a good option for unconscious patients.

Researchers have shown that visual motor skills can be improved by practicing visual skills for optimal motor performance during sport. The aim of this research was to study the effect of 6 visual training on vision functions skilled players in Badminton sport. The participants of this research were skilled badminton players from Esfahan province. 60 persons (range of age: of 25-30) were divided into two group: experimental group and control group randomly. After the presence of the two groups in pre-test, the experimental group participated in visual training and control group in watching badminton match movie, both for six weeks and three sessions per week and in the last session, both groups participated in post-test. These tests included close-far chart test (hart chart), two rows Saccades test, and test of bringing closes a pencil (prism test), coordination of eye-hand test, and the time of vision reaction test. The data was analyzed by ANCOVA analyses test (p≤0.05).The results indicated that in some visual function (included Visual reaction time, Tracking and Visual concentration   in experimental group was better than control group.

In the recent two decades, CdTe thin-film solar cells have been used due to their proper efficiency and low manufacturing cost. The transparent conducting oxide (TCO) applied in front of them has an important role in improving performance both optically and electrically. In this paper, we have used molybdenum trioxide (MoO3) as a TCO layer, and we also have done a comparison between this and other common TCO layers such as tin oxide (SnO2), zinc oxide (ZnO) and titanium dioxide (ZnO) and then examined solar cell parameters in each structure. Numerical simulations of aforesaid CdTe solar cell structures have been done employing SCAPS software. Results indicate the electrical and optical parameters of CdTe/CdS solar cell with a MoO3 TCO layer which has been improved compared with other structures so that the efficiency of it reaches to 14.72% .This value is 0.64%, 0.51%, and 0.1% higher than similar cells with transparent oxide layer SnO2, TiO2, and ZnO, respectively.

Estimating parameters of the circuit model of photovoltaic (PV) cells and modules is one of the most important challenges in solar energy. Today, with the development and proliferation of the application of optimization algorithms, the problem of estimating the parameter of the photovoltaic module can be converted into an optimization problem. In this paper, using the Ant Lion Optimizer (ALO) algorithm, all parameters of the two-diode model of the photovoltaic system are determined. This algorithm is a population-based algorithm that has a fast convergence speed and obtains reliable results. Also, to verify the accuracy of the results, the results of the ALO algorithm were compared with the results of the Gravitational Search Algorithm (GSA), Harmony Search (HS), Pattern Search (PS) and experimental points for the RTC France photovoltaic cell and the photovoltaic module Photowatt-PWP 201. As per the simulation results, the root mean square error (RMSE) given by ALO algorithm is lower than that of other three algorithms, which signifies the more precision provided by ALO in estimating the PV cell / module parameters.

Compared to the individuals with a normal arch structure, those with high or low arch can be at an increased risk of overuse injuries. The risk of overuse injury among athletes is high due, in part, to the repeated loading of the lower extremities. The current study aimed to determine if foot type (high-arched or normal) results in differences in plantar pressure during two badminton-specific movements (right-reverse lunge and right-lateral lunge).
Twenty badminton players (10 with normal feet and 10 with higharched feet) completed five trials in both right-reverse and right-lateral lunge, while in-shoe pressure data were collected at 100 Hz. The peak pressure and mean pressure were analyzed among the subjects for five major anatomical regions of the foot, using the independent t test in SPSS version 20. The foot type was determined by the foot posture index (FPI) (α Results showed that the plantar pressure characteristics of normal and high-arched feet were different; such that in high-arched feet, as compared to normal subjects, there were significantly fewer pressure strikes in the medial (P=0.010) and lateral (P=0.002) mid-foot in right-reverse lunge and this was significantly higher in forefoot (P=0.003) and toes (P=0.010). However, the peak (P=0.157) and mean (P=0.104) pressure in the heel was higher but not significant. In the right- lateral lunge, we found statistically lower peak pressure stroke for the lateral mid-foot (P=0.010) and forefoot (P=0.011); however, the mean pressure was lower in the lateral (P=0.010) and medial (P=0.040) mid-foot and forefoot (P=0.120), although it was not significant in the forefoot.
Results showed that the medial longitudinal arch of the foot might cause pressure differences in the feet among the players with normal and higharched feet. As the results demonstrated, in high-arched feet, there are some regions where plantar pressure is higher and some where it is lower. Therefore, in order to prevent the badminton players from suffering probable foot injuries, attention should be paid to the compatibility of the insole/shoe and the medial longitudinal arch and other areas of the foot that suffer more pressures than normal subjects.

In this paper, the TCO/a-Si:H(n)/c-Si:H(i)/c-Si(p)/c-Si:H(i)/BSF/TCO/Ag Bifacial HIT (Heterojunction with intrinsic thin-layer) solar cells was analyzed and designed by AFORS-HET Software. We consider the emitter and BSF layers thickness is constant, then the influences of wafer and intrinsic layer thickness, Densities of interface defects (Dit), and using three different types BSF layer and compare the output from these three types of structure with structure without the BSF layer, Solar cell efficiency is studied And the best available mode for optimum cell is selected. It is noteworthy that according to the simulation results, use a layer of intrinsic microcrystalline layer of a-Si: H (n) / c-Si (p) and c-Si (p) / a-Si: H (p ) Density of states and combined carriers reduce, Increase the efficiency of silicon solar cells is the numerical value of 28%.

As human sciences has the face of gradually evolution, it has different and various periods. Analytical and historical approach toward science periods, leads to different periods. In some cases in different scientific era, division is based on date. By reviewing lots of them such as philosophy, verbal, tenet and hadith. The terms like The Eternal and The later generations in evaluating hadith in different periods are remarkably important. Debates on origin, history and circumstances of this division help us so much to understand better. Mostly to Sheikh Toosi is called past The Eternal,before that, Imams period ia called ancient.From Sheikh Toosi to Seyed Ibn Tavous and Allameh Helli is called Fetrat and after that is called The later generations. From past to The later generations is so important. In fact these two periods and its criterion and acale play an important role in cceptance or rejecting the Shiahs Hadith.
