Background: This clinical trial aims to evaluate the color changes of direct resin composite veneer (DCV) restorations based on spectrophotometric analysis of 4 different types of resin composites between the baseline immediately after polishing and after one year of follow-up. Materials and methods: 28 patients were assessed for eligibility for participation, aged between 18 and 38 years old, who indicated for DCV restorations in anterior maxillary teeth were considered for participation in this study. In total, 25 patients who met the inclusion criteria were selected (6 males and 19 females, mean age: 20.9 at the time of restoration placement), and 3 patients were excluded. Partic

Background: Although pain after laparoscopic cholecystectomy is less intense than after open Cholecystectomy, some patients still experience considerable discomfort, and use of local anaesthetics irrigation is controversial.

Objectives :to evaluate the effect of intraperitoneal and port site instillation of local anaesthetics on pain relief in the first 6 hours postoperatively.

Patient and Method: Forty patients underwent elective laparoscopic cholecystectomy were included in this study and sample was divided into two equal groups. Group A received 20 ml of 0.9% normal saline instilled in the gallbladder bed, while group B received 20 ml of 0.25% bupivacaine instilled in

Two locally isolated microalgae (Chlorella vulgaris Bejerinck and Nitzschia palea (Kützing) W. Smith) were used in the current study to test their ability to production biodiesel through stimulated in different nitrogen concentration treatments (0, 2, 4, 8 gl ), and effect of nitrogen concentration on the quantity of primary product (carbohydrate, protein ), also the quantity and quality of lipid. The results revealed that starvation of nitrogen led to high lipid yielding, in C. vulgaris and N. palea the lipid content increased from 6.6% to 40% and 40% to 60% of dry weight (DW) respectively.Also in C. vulgaris, the highest carbohydrate was 23% of DW from zero nitrate medium and the highest protein was 50% of DW in the treatment 8gl. Whil

The paper aims at initiating and exploring the concept of extended metric known as the Strong Altering JS-metric, a stronger version of the Altering JS-metric. The interrelation of Strong Altering JS-metric with the b-metric and dislocated metric has been analyzed and some examples have been provided. Certain theorems on fixed points for expansive self-mappings in the setting of complete Strong Altering JS-metric space have also been discussed.

Background: Animal bite is one of the public health problems all over the world, especially in poor countries. Animal bites have an impact on human health due to rabies disease, which is a viral transmitted disease from animal to human with a high mortality rate.
Objective: To determine the epidemiological characteristics of animal bite cases by person, time, and place.
Method: Descriptive cross sectional study was done by reviewing cases caused by animal bites., Data including the demographic characteristics of age, gender, occupation, site of bite, and attending health institutions searching treatment were all included.
Results: There were 11600 animal bite cases. Most of bites caused by stray dogs 11577(99.8%), and the males

This work evaluates the influence of combining twisted fins in a triple-tube heat exchanger utilised for latent heat thermal energy storage (LHTES) in three-dimensional numerical simulation and comparing the outcome with the cases of the straight fins and no fins. The phase change material (PCM) is in the annulus between the inner and the outer tube, these tubes include a cold fluid that flows in the counter current path, to solidify the PCM and release the heat storage energy. The performance of the unit was assessed based on the liquid fraction and temperature profiles as well as solidification and the energy storage rate. This study aims to find suitable and efficient fins number and the optimum values of the Re and the inlet tem

     Twelve cigarette  tobacco samples of various brands and origins   were gathered from local markets of Iraq. . The C_Rn  was determined utilizing CR-39 track detectors which were exposed to the various brands of cigarettes tobacco for 45 days. The  results demonstrated that the highest value of ²²²Rn concentration was )157 Bq/m³( in Macbeth cigarette sample of Brazilian origin and the lowest value of C_Rn was (76.3 Bq/m³ (in Sumer cigarette sample of Iraqi origin,with an average value of (106.53±22.3 Bq/m³). The outcomes have demonstrated that cigarettes of a Brazilian origin contain higher C_Rn tha
