Preparation of insulating concrete and testing its thermal conductivity and porosity and mechanical resistance and modelling the porous medium of it
Majda Barmada, Amer Haj Taleb, Rolly Tawfeek Mardelly
Abstract:
Thermal insulation plays a very important role in the field of energy conservation in buildings and in saving the cost of heating and air – conditioning equipment and the fuel necessary for that.
In the first phase of this research ,three models for concrete insolation were prepared which included in their composition cement and aluminium powder and differ from each other by adding sodium hydroxide, sodium chloride and calcium carbonate to the cement with aluminium powder, which reacts with lime located in the cement and releases hydrogen gas that leaves the dough to be replaced by air to get porous structure. In this phase, the thermal conductivity test is carried out using a thermocouple measurement device, density and porosity measurement using a sensitive balance with immersion of samples in water, and measurement of sound absorption coefficient using receiver and transmitter of vibration waves and finally conducting mechanical resistance test using pressure test application device to obtain samples of insulating concrete with low thermal conductivity and low pores 22.1% and with bulk densities ranging from and absorption of sound coefficient ranges from (0.269- 0.14),and mechanical resistance ranging from (0.9-5.89) Mpa. In the second phase: a model was provided for the study of porous media based on the fractal theory to create a relationship that identifies the effective thermal conductivity (ETC) coefficient of two samples manufactured from the same insulating material, for two different humidity degrees: Sw (0.291-0.313) -the obtained the ETC for the first sample was0.1246, and for the second sample: 0.1309 – and to determine the characteristic dimensions (L, C) of the modeling, the dimension of porous and the iteration number (n).

Abdullah Basheer AL-Anazi, Abdulrahman Riyadh Altujjar, Omar Riyadh Altujjar
Abstract: Aim of the study is to estimate the awareness about glaucoma among the attendees of King Abdul-Aziz University Hospital (which is one of the big hospital in Riyadh).In addition, to assess the relationship between the awareness and knowledge about glaucoma across the socio-demographic characteristics. Which will help to develop educational and screening programs of glaucoma. In turn, patient might come in early stage of the disease therefore minimizing its complication. We Hypotheses that People in the central region of Saudi Arabia are fully aware about glaucoma and its related health issues. Our study is primary care, cross sectional study questioners. A sample of 469 patients attending ophthalmology outpatient clinic took part in filling in the glaucoma awareness questionnaire. Among these participants, 250 (53.3%) and 219 (46.8%) were males and females respectively.in the age, mean ±SD [Range]; 38.6 ±14.5 [14-80] years old. Results: The majority of the interviewed people had secondary or higher school education (86.3%) and were employed (44.3%); two of them refused to give any background about their educational level. Out of the 455 who agreed to respond to the monthly income question, most of them had a monthly income of more than 5000 SR. It is worth noting that most of the interviewed were not suffering from either diabetes or hypertension. Table 1. The question measuring the awareness of glaucoma revealed that approximately 67% had heard of glaucoma through doctors, families, media and friends. Those who managed to answer the questions correctly, and who had already heard of glaucoma, were 312 (66.5%).Conclusions: Assessing the glaucoma knowledge, the scores showed that majority had good knowledge of glaucoma with only a few having excellent knowledge. However, only two (0.6%) of the respondents had very poor knowledge of glaucoma. Table 4.

PHYSIOTHERAPEUTIC REHABILITATIVE APPROACH IN MANDIBULAR CERVICAL SKULL DYSFUNCTION
Eriona Fila, Enzo Ruberti, Stefano Lecora,Gennaro Rocco, Andrea Giacalone
Abstract:
Background: Temporomandibular dysfunctions present a multifactorial etiopathogenesis that require a multidisciplinary approach in which the rehabilitation performed by physiotherapists assumes a role of primary importance. Despite the high number of publications, the studies observed purely in the physiotherapeutic field are in a very low percentage. Methods: To this end, a literature search was conducted on the Pubmed database, using three key words: “Mandibular temporal Joint rehabilitation”, “Physical therapy temporomandibular”, “Rocabado” and “Physical therapy”. The total number of items identified is 1594, of which 40 were deemed relevant to the research through the review process.Results:After examining the selected studies, the most effective management of temporal mandibular dysfunctions appears to be the conservative approach that includes non-thrust joint mobilization and HVLA thrust manipulation to the TMJ and / or upper cervical articulations, and dry needling or acupuncture to the lateral pterygoid muscle and posterior periarticular connective tissue. Conclusion:Through such therapeutic modalities it is possible to have an impact on the anatomical structures directly connected to the etiology of the dysfunction.

KABAT REHABILITATION FOR FACIAL NERVE PARALYSIS: PERSPECTIVE ON NEUROKINETIC RECOVERY AND REVIEW OF CLINICAL EVALUATION TOOLS
Andrea Giacalone , Teresa Sciarrillo,Gennaro Rocco, Enzo Ruberti
Abstract:
Background: Facial nerve paralysis (cranial nerve VII) is one of the most common neurological disorders affecting the cranial nerves. Symptoms of this disorder are not life threatening but can cause worry and discomfort. Peripheral paralysis of the facial nerve is a disabling pathology; it affects the functional, psychological, social and occupational aspects of life. The Kabatre habilitation method for facial paralysis can evoke or restore the neuromuscular circuit through stimulation of the proprioceptors, restoring the normal functionality of nerve endings in the muscles. Objectives: This study intends to demonstrate how patients can benefit, both aesthetically and functionally, from proper clinical evaluation followed by a rehabilitation program based on the Kabat method. Methods :The study is qualitative and has an experimental and multicenter design. Data was collected through a clinical record and using a specific questionnaire for this type of pathology for monitoring the satisfaction and improvements of the patient; Functionality evaluation of the facial nerve was based on the SFG Sand H-B scales.Results:The study has shown that patients, who were treated with steroid-antiviral therapy and PNF rehabilitation method, recovered motor abilities of the paralyzed hemi facial. In addition, patients improved thermal, pain and position sensitivity. Conclusions: It is possible to conclude that a correct and timely diagnosis is very important, as well as using valid evaluation and data collection tools, properly managing the improvement through standardized clinical evaluation scales and a proper medical and physiotherapy treatment plan. Limitations: The limits encountered during the study were: limited number of samples; the short period of observation, not enough to include severe prognosis and full improvement of expressive gestures.

Sjogren’s syndrome presented with sever motor neuron disease
Abdulrahman A. Khormi, Fajer Al Tamimi, Sami Alrasheedi, Talal Al Kuhaimi, Ahmed Al-Shaiklh
Abstract: Sjögren`s syndrome (S.S.) is a chronic, systemic autoimmune disease characterized by lymphocytic infiltration of the exocrine glands. It is an elaborate involvement of the lacrimal and salivary glands, which eventually lead to keratoconjunctivitis sicca and xerostomia. It occurs in two forms, primary or secondary (associated with another autoimmune disease, most commonly rheumatoid arthritis). The American College of Rheumatology (ACR) Board of Directors and the European League Against Rheumatism (EULAR) Executive Committee have approved classification criteria that aids at primary Sjogren`s Syndrome diagnosis. It includes labial
salivary gland biopsy with evidence of lymphocytic infiltrate, positive ant SSA , ocular staining score of 5 or more, Shirmer`s test positivity and unstimulated whole saliva flow less than or equal to 1ml/minute.The application of this criteria requires exclusion of conditions that may mimic S.S. such as hepatitis C infection, AIDS,IgG4 disease
and Sarcoidosis.(1) S.S. has many neurological manifestations .In Sjögren’s syndrome-associated neurological complications, Neurological symptoms often precede the manifestation of sicca symptoms. (2) Motor neuron disease (MND) is a rarely recognized complication in Sjögren’s syndrome. (3) Here in we present a case of lady with primary Sjogren and this rare neurological manifestation.
