Ahmad Nasrat Al-juboori
International Journal of Otolaryngology , 2013, DOI: 10.1155/2013/401289
Abstract: Foreign bodies (FB) in the external auditory canal are relative medical emergency. The objective of this study was to describe the types of FB and their complications and to highlight on new FB not seen before which was the bluetooth devices that were used for cheating during high school examination in Al-Fallujah city. This was a two-year hospital-based descriptive study performed in the Department of Ear, Nose and Throat (ENT), Al-Fallujah General Hospital, from June 2011 to May 2013; during this period, 224 FB had been extracted from 224 patients. Beads were extracted from 68 patients (30.4%), cotton tips were extracted from 50 patients (22.3%), seeds and garlic were extracted from 31 patients (13.8%), papers were extracted from 27 patients (12.1%), insects were extracted from 24 patients (10.7%), button batteries were extracted from 13 patients (5.8%), and bluetooth devices were extracted from 7 patients (3.1%). Most of the cases did not develop complications (87.5%) during extraction. The main complications were canal abrasion (4.5%). Proper instrumentation allows the uncomplicated removal of many FB. The use of general anesthesia is preferred in very young children. Bluetooth device objects should be considered as new aural FB, especially in our territory. 1. Introduction Foreign bodies (FB) in the external auditory meatus are most commonly seen in children who have inserted them into their own ears. Children may present asymptomatically, or with pain or a discharge caused by otitis externa. Adults are often seen with cotton wool or broken matchsticks which have been used to clean or scratch the ear canal [1]. Live insects in the ear, commonly small cockroaches [2], are annoying due to discomfort created by loud noise and movement. FB in the ear is relatively common in emergency medicine. However, attempts of removal made outside the healthcare setting by untrained persons can result in complications of varying degrees [3]. An aural FB can involve damage to tympanic membrane or middle ear by itself or by improper management during removal. The etiology of FB in the ear has been ascribed to general curiosity and a whim to explore orifices in children, playful insertion of FB into others’ body parts, accidental entry of foreign body, preexisting disease in ear causing irritation, and habitual cleaning of ear and nose with objects like ear buds [4, 5]. FB in ear can be classified in many ways like organic-inorganic, animate-inanimate, metallic-nonmetallic, hygroscopic-nonhygroscopic, regular or irregular, soft or hard, and so forth, according to
An Overview of Recently Developed Coupled Simulation Optimization Approaches for Reliability Based Minimum Cost Design of Water Retaining Structures  [PDF]
Muqdad Al-Juboori, Bithin Datta
Open Journal of Optimization (OJOp) , 2018, DOI: 10.4236/ojop.2018.74005
Abstract: This paper reviews several recently-developed techniques for the minimum-cost optimal design of water-retaining structures (WRSs), which integrate the effects of seepage. These include the incorporation of uncertainty in heterogeneous soil parameter estimates and quantification of reliability. This review is limited to methods based on coupled simulation-optimization (S-O) models. In this context, the design of WRSs is mainly affected by hydraulic design variables such as seepage quantities, which are difficult to determine from closed-form solutions or approximation theories. An S-O model is built by integrating numerical seepage modeling responses to an optimization algorithm based on efficient surrogate models. The surrogate models (meta-models) are trained on simulated data obtained from finite element numerical code solutions. The proposed methodology is applied using several machine learning techniques and optimization solvers to optimize the design of WRS by incorporating different design variables and boundary conditions. Additionally, the effects of several scenarios of flow domain hydraulic conductivity are integrated into the S-O model. Also, reliability based optimum design concepts are incorporated in the S-O model to quantify uncertainty in seepage quantities due to uncertainty in hydraulic conductivity estimates. We can conclude that the S-O model can efficiently optimize WRS designs. The ANN, SVM, and GPR machine learning technique-based surrogate models are efficiently and expeditiously incorporated into the S-O models to imitate the numerical responses of simulations of various problems.
Palm Vein Verification Using Gabor Filter
Ali Mohsin Al-Juboori
International Journal of Computer Science Issues , 2013,
Abstract: Palm vein authentication is one of the modern biometric techniques, which employs the vein pattern in the human palm to verify the person. The merits of palm vein on classical biometric (e.g. fingerprint, iris, face) are a low risk of falsification, difficulty of duplicated and stability. In this research, a new method is proposed for personal verification based on palm vein features. In the propose method, the palm vein images are firstly enhanced and then the features are extracted by using bank of Gabor filters. Then Fisher Discriminated Analysis (FDA) is used to reduce the dimension of the features vectors. For vein pattern verification, this work uses Nearest Neighbors method. The EER of the proposed method is 0.2335%.
Zenker’s diverticulum. A rare cause of dysphagia
Ahmed N. Al-Juboori,Salih H. Al-Essawi
Saudi Medical Journal , 2013,
Abstract: Zenker’s diverticulum or pharyngeal pouch is a herniation of pharyngeal mucosa through a defect located on the posterior pharyngeal wall, in an area of natural weakness between the 2 parts of the inferior constrictor muscles. The incidence of presentation of pharyngeal pouch to an ear, nose, throat (ENT) specialist was estimated as 0.47 cases per 100,000 per year. It could be a rare cause of dysphagia in elderly patients, associated with regurgitation, chronic cough, aspiration, and weight loss. The etiology still unknown, but theories focus upon structural or physiological disorders of the cricopharyngeus muscle. Zenker’s diverticulum should be considered as one of the rare causes of dysphagia in elderly patients, and the treatment modalities depend on individual experience and availability of the facilities.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0067626
Abstract: Recently developed optogenetic tools provide powerful approaches to optically excite or inhibit neural activity. In a typical in-vivo experiment, light is delivered to deep nuclei via an implanted optical fiber. Light intensity attenuates with increasing distance from the fiber tip, determining the volume of tissue in which optogenetic proteins can successfully be activated. However, whether and how this volume of effective light intensity varies as a function of brain region or wavelength has not been systematically studied. The goal of this study was to measure and compare how light scatters in different areas of the mouse brain. We delivered different wavelengths of light via optical fibers to acute slices of mouse brainstem, midbrain and forebrain tissue. We measured light intensity as a function of distance from the fiber tip, and used the data to model the spread of light in specific regions of the mouse brain. We found substantial differences in effective attenuation coefficients among different brain areas, which lead to substantial differences in light intensity demands for optogenetic experiments. The use of light of different wavelengths additionally changes how light illuminates a given brain area. We created a brain atlas of effective attenuation coefficients of the adult mouse brain, and integrated our data into an application that can be used to estimate light scattering as well as required light intensity for optogenetic manipulation within a given volume of tissue.
Present Water Crises in Iraq and Its Human and Environmental Implications  [PDF]

Engineering (ENG) , 2018, DOI: 10.4236/eng.2018.106021
Abstract: Iraq is facing a serious water shortage problem now, which has not been experienced before. This is because of the reduction of flow of the Euphrates and Tigris Rivers which is due to the implementation of hydrological projects within the upstream part of the catchment and climate change. Mismanagement of water resources within Iraq made the problem graver. It is believed that serious discussion with all riparian countries to reach an agreement to share the water of the two rivers and their tributaries is desperately needed. In addition, a prudent scientific strategy should be implemented and put into practice to overcome this problem in Iraq. In addition, the key positions within the Iraqi Ministry of Water Resources should be given to people having real experience in the water resources sector to ensure discreet and prudent management of the problem.

Abstract: The current study investigated the effect of natural diosgenin extracted from fenugreek seeds, in comparison with the pure standard diosgenin, plus chromium chloride (CrCl3) supplementation on high-cholesterol fed Japanese quails. Quails were randomly divided into four groups. Group one (n = 25) fed experimental diet only (control; contained basal diet supplemented with 1% cholesterol), group 2 (n = 20) fed experimental diet supplemented with CrCl3 only (400 g kg-1 of body weight), groups 3 and 4 (n = 30 per group) were fed experimental diet supplemented with either 0.5% (w/w) of extracted diosgenin plus CrCl3 or pure standard diosgenin (0.5%) plus CrCl3 respectively, for 12 days. Blood samples were collected at days 0 and 12 for measuring levels of lipid profile. The work was carried out at Applied Science University and Amman University, Amman, Jordan during the period from October 2009 through October 2010. The mean levels of total cholesterol (TC) in control quails at d12 was significantly (p<0.01) increased compare to those at d0. Supplementation of diet with CrCl3 alone or CrCl3 with diosgenin either extracted or pure standard for 12 days showed a significant (p<0.01) decrease in TC and low density lipoprotein cholesterol (LDL-C) levels as compared to those in the control quails. While, high density lipoprotein cholesterol (HDL-C) increased significantly (p<0.01) in quails supplemented with diosgenin and CrCl3. At d12, the mean Superoxide Dismutase (SOD) activities in erythrocytes of quails in all supplemented groups was significantly (p<0.01) increased as compared to those in control group and was more pronounced in erythrocytes of quails supplemented with pure standard diosgenin plus CrCl3. These results indicated that the combined diosgenin and CrCl3 supplementation to high-cholesterol fed quails might induce a protective effect by both regulating lipid and antioxidative damage.
