Shear Behavior of Steel I-Beams Strengthened With CFRP Strips

This paper studies the behavior of simply supported steel I-beams strengthened with carbon fiber reinforced polymers (CFRP) strips on the web as shear reinforcement. The experimental program contains seven simply supported steel beams. One of them was considered as a control beam and the other specimens were strengthened with different schemes; varying the position of CFRP strips to the web, its number of layers and its angle of orientation. The results show that applying CFRP strips on the web of the steel I-beams was an effective strengthening method for increasing the load bearing capacity and decreasing the deformations. Using two layers of diagonal CFRP strips on both sides of the web realized the highest increasing in the load capacity. Moreover, finite element analysis method has been utilized to analyze the tested specimens using ANSYS. A great convergence between the experimental results and the corresponding ones obtained from finite element simulation

Treatment results and prognostic factors of pediatric neuroblastoma: a retrospective study

<p>Abstract</p> <p>Background</p> <p>We conducted a retrospective analysis to investigate treatment results and prognostic factors of pediatric neuroblastoma patients.</p> <p>Methods</p> <p>This retrospective study was carried out analyzing the medical records of patients with the pathological diagnosis of neuroblastoma seen at South Egypt Cancer Institute, Assiut University during the period from January 2001 and January 2010. After induction chemotherapy, response according to international neuoblastoma response criteria was assessed. Radiotherapy to patients with residual primary tumor was applied. Overall and event free survival (OAS and EFS) rates were estimated using Graphed prism program. The Log-rank test was used to examine differences in OAS and EFS rates. Cox-regression multivariate analysis was done to determine the independent prognostic factors affecting survival rates.</p> <p>Results</p> <p>Fifty three cases were analyzed. The median follow-up duration was 32 months and ranged from 2 to 84 months. The 3-year OAS and EFS rates were 39.4% and 29.3% respectively. Poor prognostic factors included age >1 year of age, N-MYC amplification, and high risk group. The majority of patients (68%) presented in high risk group, where treatment outcome was poor, as only 21% of patients survived for 3 year.</p> <p>Conclusion</p> <p>Multivariate analysis confirmed only the association between survival and risk group. However, in univariate analysis, local radiation therapy resulted in significant survival improvement. Therefore, radiotherapy should be given to patients with residual tumor evident after induction chemotherapy and surgery. Future attempts to improve OAS in high risk group patients with aggressive chemotherapy and bone marrow transplantation should be considered.</p

On modeling two immune effectors two strain antigen interaction

In this paper we consider the fractional order model with two immune effectors interacting with two strain antigen. The systems may explain the recurrence of some diseases e.g. tuberculosis (TB). The stability of equilibrium points are studied. Numerical solutions of this model are given. Using integer order system the system oscillates. Using fractional order system the system converges to a stable internal equilibrium. Ulam-Hyers stability of the system has been studied

Symptoms-Related Distress among Patients Receiving Adjuvant Therapy: Radical Mastectomy versus Lumpectomy

Background: Breast cancer is the most common cancer in women worldwide. Although adjuvant therapy after breast-conserving surgery or mastectomy reduces the risk of breast cancer coming back but it induces many of physiological and psychological effects. The aim of the current study was to compare the Symptoms-related distress among patients receiving adjuvant therapy: Radical Mastectomy versus Lumpectomy at a University Hospital. Research Questions: Q1: What are the symptoms related distresses among radical mastectomy and lumpectomy patients receiving adjuvant therapy? Q2: Is there a difference in symptoms related distress between radical mastectomy and lumpectomy patients receiving adjuvant therapy? Design: A comparative descriptive -non-experimental design was utilized to achieve the aim of the current study. Tools: I) Socio-demographic and medical data sheet: It included data related to the studied subjects such as age, gender, marital status, types of received chemotherapy,…..etc. Tool II: Rotterdam Symptom Checklist (RSCL); it is useful in measuring the symptoms reported by cancer patients. It aims to enhance the insight into the consequences of the disease and its treatment. Setting: The study was conducted at the Nuclear Medicine Unit at Kasr Al-Aini Educational Hospital; affiliated to Cairo-University-Egypt. Subjects: A convenient sample of 60 adult female patients divided into two equal groups, patients with radical mastectomy (n=30) and patients with lumpectomy (n=30) both groups received chemotherapy after surgery. Results: 80% of mastectomy and lumpectomy cases overall their age was between 40 and less than 60 years old. 33.3% of the study sample can read and write. The study pointed out that 48.3% of the sample had breast cancer between 2 and less than 6 months. While 50% of them between 6 to less than 12 months with Mean+SD= 5.65+2.There was a perfect correlation between total score of RSCL and physical total score =0.826, 0.829 &amp; 0.828 for patients overall cases, mastectomy cases only &amp; lumpectomy cases only respectively. Also there was a strong correlation between the RSCL total score and psychological total score=0.705, 0.747 &amp; 0.668 for the patients overall cases, mastectomy cases only &amp; lumpectomy cases only respectively. Conclusion: The lumpectomy cases scored generally their physical, psychological &amp; activity level impairment status much better than the mastectomy cases. Also lumpectomy cases their general QOl was better than the mastectomy cases. Recommendation of the study: 1-More close physical, psychological support must endorse in nursing care for patients with mastectomy. 2-QOL advanced tool is recommended on survey scale to evaluate patients' condition with mastectomy &amp; lumpectomy. 3-All patients with breast cancer must join a rehabilitation program before &amp; after proceed in either mastectomy or lumpectomy surgical management.

On the Consistency of the Solutions of the Space Fractional Schr\"odinger Equation

Recently it was pointed out that the solutions found in literature for the space fractional Schr\"odinger equation in a piecewise manner are wrong, except the case with the delta potential. We reanalyze this problem and show that an exact and a proper treatment of the relevant integral proves otherwise. We also discuss effective potential approach and present a free particle solution for the space and time fractional Schr\"odinger equation in general coordinates in terms of Fox's H-functions

Local Entropy and Standard Deviation for Facial Expressions Recognition in Thermal Imaging

Emotional reactions are the best way to express human attitude and thermal imaging mainly used to utilize detection of temperature variations as in detecting spatial and temporal variation in the water status of grapevine. By merging the two facts this paper presents the Discrete Cosine Transform (DCT) with Local Entropy (LE) and Local Standard Deviation (LSD) features as an efficient filters for investigating human emotional state in thermal images. Two well known classifiers, K-Nearest Neighbor (KNN) and Support Vector Machine (SVM) were combined with the earlier features and applied over a database with variant illumination, as well as occlusion by glasses and poses to generate a recognition model of facial expressions in thermal images. KNN based on DCT and LE gives the best accuracy compared with other classifier and features results

Coyote multi-objective optimization algorithm for optimal location and sizing of renewable distributed generators

Research on the integration of renewable distributed generators (RDGs) in radial distribution systems (RDS) is increased to satisfy the growing load demand, reducing power losses, enhancing voltage profile, and voltage stability index (VSI) of distribution network. This paper presents the application of a new algorithm called ‘coyote optimization algorithm (COA)’ to obtain the optimal location and size of RDGs in RDS at different power factors. The objectives are minimization of power losses, enhancement of voltage stability index, and reduction total operation cost. A detailed performance analysis is implemented on IEEE 33 bus and IEEE 69 bus to demonstrate the effectiveness of the proposed algorithm. The results are found to be in a very good agreement

On the solvability of a nonlinear functional integral equations via measure of noncompactness in

Using the technique of a suitable measure of non-compactness and the Darbo fixed point theorem, we investigate the existence of a nonlinear functional integral equation of Urysohn type in the space of Lebesgue integrable functions Lp(RN). In this space, we show that our functional-integral equation has at least one solution. Finally, an example is also discussed to indicate the natural realizations of our abstract result
