Background: Diabetes mellitus is a major risk factor for chronic periodontitis (CP) and hyperglycemia has an important role in the enhancement of the severity of the periodontitis. It has been reported that the progression of CP causes shifting of the balance between bone formation and resorption toward osteoclastic resorption, and this will lead to the release of collagenous bone breakdown products into the local tissues and the systemic circulation. Cross-linked N-telopeptide of type I collagen (NTx) is the amino-terminal peptides of type I collagen which is released during the process of bone resorption. This study was conducted to determine the effects of nonsurgical periodontal therapy on serum level of NTx in type 2 diabetic patients with chronic periodontitis (CP) and in systemically healthy patients with CP and to correlate NTx level with the clinical periodontal parameters in the studied groups. Materials and methods: The studied sample consisted of ninety subjects of both genders with an age range (35-55). They were divided into three groups, the first group consisted of 30 subjects with healthy periodontium and systemically healthy (control group), the second group consisted of 30 patients having chronic periodontitis and type 2 diabetes mellitus (CPDM) group, and the third group consisted of 30 patients with chronic periodontitis only and systemically healthy (CP) group. All the subjects enrolled in this study were with normal body mass index. The clinical periodontal parameters measured were plaque index (PLI), gingival index (GI), probing pocket depth (PPD), and relative attachment level (RAL). The blood samples were collected from all individuals and examined to measure the serum level of NTx using enzyme-linked immune sorbent assay (ELISA). Patients with chronic periodontitis were treated with scaling and root planning (SRP) and recalled for further measurements of the clinical periodontal parameters and collection of the blood sample to measure the serum level of NTx after eight weeks. Results: All the clinical periodontal parameters at the baseline were higher than that after treatment. PPD and RAL were highest in CPDM group followed by CP. Regarding the level of NTx at the baseline; it was highest in CPDM group followed by CP group then the control group. After treatment, results revealed a reduction in NTx level for both CPDM and CP groups. Regarding the correlation between the clinical periodontal parameters and NTx level, the results revealed almost a non-significant weak positive correlation. Conclusions: SRP is an impactful procedure and results in the improvement of all the clinical periodontal parameters and reduction in the serum level of cross-linked N-telopeptide of type I collagen which could be considered as a good bone resorption marker in the studied groups.
Various simple and complicated models have been utilized to simulate the stress-strain behavior of the soil. These models are used in Finite Element Modeling (FEM) for geotechnical engineering applications and analysis of dynamic soil-structure interaction problems. These models either can't adequately describe some features, such as the strain-softening of dense sand, or they require several parameters that are difficult to gather by conventional laboratory testing. Furthermore, soils are not completely linearly elastic and perfectly plastic for the whole range of loads. Soil behavior is quite difficult to comprehend and exhibits a variety of behaviors under various circumstances. As a result, a more realistic constitutive model is

Electrical Discharge Machining (EDM) is a widespread Nontraditional Machining (NTM) processes for manufacturing of a complicated geometry or very hard metals parts that are difficult to machine by traditional machining operations. Electrical discharge machining is a material removal (MR) process characterized by using electrical discharge erosion. This paper discusses the optimal parameters of EDM on high-speed steel (HSS) AISI M2 as a workpiece using copper and brass as an electrode. The input parameters used for experimental work are current (10, 24 and 42 A), pulse on time (100, 150 and 200 µs), and pulse off time (4, 12 and 25 µs) that have effect on the material removal rate (MRR), electrode wear rate (EWR) and wear ratio (WR).

The main objective is to explore the challenges and strategies involved in translating this literary work, particularly the difficulties in translating the Baghdadi dialect and the obstacles it poses for non-native speakers. Employing a descriptive research methodology, the study examines the linguistic aspects of the translation, specifically selected conversational texts in the novel. It identifies the difficulties faced by translators in preserving the essence of the original novel and presents instances where errors occurred in translating vocabulary, conversational expressions, proverbs, and idi

Cultural awareness is becoming increasingly important in an effort to reinvigorate local urban heritage into modern production. Considering that, one of the most significant aspects of sustainability is preserving socio-cultural and environmental specificities and restoring local heritage. The aim is influencing the local identity by promoting sustainability through the revival of Islamic geometric patterns (IGP) and their performance as effective components in local urban facades. A set of indicators related to the purposes for reusing IGP in facades within three main performances (decorative, structural, and functional). Their sustainability was studied and extrapolated, and a checklist has developed and tested by Likert scale on

The proposed model allows quick and precise estimation of an adopted weighted objective function for each selected location. In addition to that for each location, a different dam height is used as a nominee for optimum selection. The VBA model includes an optimization model with a weighted objective function that includes beneficiary items (positive) , such as the available storage , the dam height allowed by the site as an indicator for the potential of hydroelectric power generation , the rainfall rate as a source of water .

The study is based on modified Von-Mises yield criterion (for non metallic material). The equations of stress distribution are obtained for the cylinder under general cases of elastic expansion, plastic initiation and elastic-plastic expansion.
A computer program is developed for evaluating the stress distribution. The solution is carried out for worst boundary conditions when the cylinder is subjected to the combination of pressure load, inertia load, and temperature gradient.
The results are presente
