Objectives: The aim of this study is to describe the demographic and clinicopathological features of parotid tumors (PT) presented at a tertiary health center in Jordan. The study also compares the findings with other studies conducted in different countries.\nMethods: This retrospective study was conducted to review the medical records of all patients who underwent parotidectomy at the University of Jordan Hospital from January 2003 to September 2014. A total of 186 patients underwent parotidectomy in this period; of them, 125 (72 males and 53 females) patients had parotid neoplasms and were included in the study. The data of those patients were analyzed for age, sex, histologic types and complications and were compared with the findings of other studies.\nResults: Benign neoplasms were found in 103 patients (82.4%) while malignant ones were found in 22 patients (17.6%). Pleomorphic adenoma was the most common pathology with 44.8% frequency of occurrence (56/125) while the Warthin Tumor was the second most frequent tumor in 25.5% cases (32/125). Mucoepidermoid carcinoma was the most common malignant tumor with a frequency of around 9% (11/125). This was followed by adenoid cystic carcinoma that accounted for 2.5% cases (3/125). In terms of complication, the most common was Frey’s syndrome reaching up to 15%. \nConclusions: The demographic distribution of PT at the site of the study was different with respect to the incidence of benign tumors, male to female ratio while the incidence of malignant ones was the same as in other parts of the world

Purpose: The objective of the study is to compare the socio-demographical\ncharacteristics of patients with psychotic disorders that engage or do not engage in\nviolent behavior against individuals, and to conduct a research on the degree of affinity\nof the victims of violence with the patient and on factors that could affect violence.\nMethodology: All patients that were treated in the psychiatry clinic during the last year,\ndiagnosed with psychotic disorder, and with a complete file were included in the study.\nThe patients were compared in two groups; these who engaged in violent acts and these\nwho did not. Furthermore, patients in the violent group were separated into two groups;\none consisting of the patients who engaged in violent behavior against immediate\nfamily members, hence the immediate violence group, and the patients who did not\nengage in violence against immediate family members, hence the distant violence\ngroup, and these three groups were compared.\nFindings: A total of 151 patients were included in the study. It was determined that\n56% of the patients with psychotic disorder have attempted violence, out of which 75%\nwere engaged in violent behavior against their immediate relatives and male patients\ndisplayed more violent attempts than females. It was observed that patients that did not\nreceive regular psychiatric therapy and that did not receive inpatient treatment\nattempted in violence more than others. It was determined that existence of positive\nsymptoms, smoking, past violence and suicidal histories increased the risk of violent\nbehavior. It was also determined that alcohol and substance abuse, previous electroconvulsive\ntherapy had no effects on violent behavior.\nResults: Violent behavior by patients with psychotic disorders increase when they are\nnot regularly followed up and they are not in therapy regularly. Especially patients with\nactive psychotic symptoms should be treated in early stages and precautions should be\ntaken against situations that could provide risk factors for violence, to decrease attempts at violence.

The Modified Cam-Clay (MCC) mathematical model is reviewed. Several extensions of the MCC model are reviewed, including kinematic hardening with bounding surface (BS), the general plasticity (GP) model, extension of the MCC model to include finite strain, and different variants of the pressure hardening rule, including bi-modulus extension, hypoplastic, and the hyperelastic potential extension. The associated flow rules coupled with different hardening equations are considered. In the review the main attention is paid to the case of the infinitesimal strains.

Today, environmental protection and sustainable development are two fundamental pillars of human existence. In this process, the major roles are played by governments and international organizations. Adherence to international obligations and peremptory rules is central to determining the role of environmental diplomacy towards sustainable development. There is no doubt that environmental development and protection would not be achieved without serious regional interactions and international cooperation. There will be no sustainable development outside a framework of international interaction and global peace. In this respect, environmental diplomacy is considered an effective approach towards protecting natural resources and ecosystems. In this regard, and in the context of a worldwide understanding, the environment is the most important factor of international convergence. The attitude toward life and life expectancy with having a consideration for human generations’ rights in the light of human rights ideals is one of the most important goals. Therefore, the international community needs a new attitude named convergence in order to act with stability in protecting global environment. Accordingly, relying on international convergence and international laws, the present research intends to clarify the evolution of international environmental law in the light of sustainable development and environmental protection within the framework of environmental diplomacy, as well as the role of governments when confronted with environmental challenges. Environmental threats and hazards, therefore, are signs of unnatural, illogical human behavior for which there is no definite answer as yet; at the present time, however, it is necessary to bolster international convergence in the light of environmental diplomacy toward protecting the environment and achieving global peace.

Over the past two decades, the Intensity-Hue-Saturation (IHS) is still one of the most common image fusion algorithms to take advantage of the complementary nature of multispectral images in the remote sensing community due to its simplicity and capability to fuse the massive volumes of high resolution images such as IKONOS and QuickBird. However, IHS method causes color distortion problem on the fused images due to the saturation changes during the fusion process. In this study, an adaptive IHS approach is proposed respect to spectral properties of the satellite sensor and the landscape features of the study areas to reduce the color distortion. Experimental results shows that the proposed approach reduce the color distortion and provide improved image quality when compared with other current approaches include traditional IHS and Generalized IHS.

In this study, historic houses from seven different localities (in Amasra, Bartin, Eregli, Goynuk, Kastamonu, Mudurnu, Safranbolu) from the Western Black Sea Region in Turkey was chosen as the study areas. In addition to the natural beauty of these historical wooden houses, they have great importance in terms of tourism and authenticity in the region. Interior wooden parts were examined in terms of finishing treatments (paint, varnish, etc.). In this context, primarily the present situations of interior wood surfaces were examined in place and the problems have been identified. Then, measures to be taken against these problems were presented according to nano-technologic application on wood surface studies carried out and finally solutions needed to be taken urgently are presented for sustainability of these structures on behalf of the future generations. Consequently, nano-technologic finishing materials were found superior in terms of; specular gloss, hardness, surface adhesion, surface resistance to cold liquids properties compared to conventional finishing materials. To summarize, by using nano-technological finishing products in renovation works in wooden internal walls, the lifespan of the wood can be extended. And thus, possible economic losses will be prevented.

Doppler ultrasound tests of 93 patients with low-grade and medium-grade carotid stenoses of left and right internal carotid arteries were conducted. The results showed that low-grade stenoses of left internal carotid artery prevail in women as compared to men (p< 0, 05), whereas medium-grade stenoses (50 – 75%) have equal frequency in men and women. Right internal carotid artery stenoses were detected more rarely than those of the left internal carotid artery. Most frequent were the hemodynamically insignificant stenoses, which were distributed with almost equal frequency among the two genders. Moderate stenoses were measured more rarely, mainly in women. Bilateral stenoses were observed in 39 of the patients who underwent the test. Low-grade stenoses again were more frequently detected than those of 50 – 75% and women were more frequently affected.

In this paper, we investigate the multiple attributes group decision making (MAGDM) problems in which attribute values take the form of interval grey uncertain linguistic variables. Firstly, we develop the interval grey uncertain linguistic variables weighted geometric (IGULWG) operator, the interval grey uncertain linguistic variables ordered weighted geometric (IGULOWG) operator and the induced interval grey uncertain linguistic variables ordered weighted geometric (I-IGULOWG) operator and study some desirable properties of the I-IGULOWG operator. Furthermore, we apply the I-IGULOWG operator and the IGULWG operator to the group decision making with interval grey uncertain linguistic information. Finally, an illustrative example for evaluating the technological SMEs\' independent innovation capacity with interval grey uncertain linguistic information is given to verify the developed approach and to demonstrate its practicality and effectiveness.

This paper presents a face detection method based on histograms of oriented gradients(HOG). The face was divided into grid regions and the HOG feature was extracted from every region and merged. To avoid repeated calculation, the integral image of HOG was used to calculate HOG in a region. The support vector machine(SVM) was used to distinguish between face and non-face. An investigation has been made on how the detection results are influenced by the way of division, the number of histograms bins and image resolution. The experimental results indicate that the refinement of division, the increase in the number of histogram bins and the resolution improvement all can improve detection rate and reduce false detection rate in a certain range. The performance of the proposed method have been evaluated on CMU/MIT testing sets and showed sufficient improvements compared to the state-of-the-art.

Building energy consumption has become a strategic issue that cannot be ignored in our social and economic development. So how to choose a reasonable lighting solution, to design an advanced configuration control system and to improve the scientific management level of lighting to reduce energy consumption have great economic and social significance. In this paper, using the Gulf HW-BA5201 direct digital controller（DDC）as the hardware devices and ForceControlV6.0 as the supervisory control and data acquisition (SCADA)we design a lighting control system. This system can accomplish the goal of local/remote, manual/automatic control for each lighting group in the laboratory. This lighting monitoring and control system can achieve the centralized monitoring of the status of the lighting group and achieve the goal of automatic lighting control according to the switch of the indoor light illumination.

We present a novel approach called Quadrilateral Collapse Compositing (QCC) to improve the efficiency of gradient-domain compositing of large image, which could be implemented in significantly reduced time and memory. Firstly, our algorithm divides an original source image into many quadrilateral patches, and collapses all of quadrilateral patches (discarding inner pixels and reserves the border pixels) to constitute two low resolution images (Collapse-images) on which the image compositing operator is implemented. Finally according to the solution of Collapse-images the result image is evaluated by concurrently computing inner pixels of every quadrilateral patch on GPU. The evaluation of these patches is independent to each other so that our algorithm has better parallelism. The reduction of time and memory is achieved by solving Poisson equation on low resolution and inner interpolation on quadrilateral patches. The major merits of our approach are demonstrated by performing large image composite (whose size is about multi-Gigabyte) in significantly reduced time and memory while achieving visually identical results.

The impact of the growing introduction of the wind turbine in Moroccan electrical grid is significant in terms of electrical energy quality. The fluctuation of the wind speed can generate fluctuation of the voltage and power. Another big problem is a disconnection of the wind turbine from the electrical grid caused by voltage dip. In this communication, we describe a solution for wind turbines using Doubly Feed Induction Generator (DFIG) to overcome the disruption caused by Voltage dips. During voltage sag, high current is generated in the rotor and could damage the converter. We present the passive CROWBAR system to show his contribution and limitations face the grid defaults. Simulations results show the rotor and stator current, the torque, active and reactive power before and after the implementation of the solution.
