Urban Development in the Heritage Cities, Wadi Mazab

This research paper, which was prepared under the patronage of Prince Sultan Bin Salman’s Chair for Urban Heritage, the problem of housing in heritage cities and how to adopt the urban heritage as a reference for the development of housing models with environmental specifications, Economic and social sustainability basedon the analysis of local traditional architecture and the extraction of principles and characteristics. This character is to be employed and adopted in new urban models. The aim of this paper is to draw on a distinctive architectural philosophy organization and structure of the field and social and social pressures contributing to the needs of the population and the sustainability of the idea of Al-Amrani This is a sample of the housing models for the success factors and the reasons behind the future housing projects. At the beginning of this research, we relied on the diagnosis and development of traditional buildings in the old palaces as housing models which has managed to provide, over a thousand years, adequate accommodation for the desert climate and environment-friendly. The project of the new palace of Tennmeren and Kastravaltal are reviewed, whichare considered the most important models of successful housing in the valley of Mazab which will contribute to the formulation of new concepts to maintain our urban patterns and continuity in light of the changes of the age. In order to avoid the disincentives to the success of these projects, we reviewed the Palace of Hamriyat to identify the most important shortcomings and to identify the most important reasons In conclusion, we concluded with a number of recommendations, based entirely on the need to adopt the principles of conventional housing

Vector spaces as unions of proper subspaces

In this note, we find a sharp bound for the minimal number (or in general, indexing set) of subspaces of a fixed (finite) codimension needed to cover any vector space V over any field. If V is a finite set, this is related to the problem of partitioning V into subspaces.Comment: 8 pages, LaTex; to appear in "Linear Algebra and its Applications

A 3 Points Vision Based Approach for MAV Localization in GPS Denied Environments

International audienceThis paper introduces a new method to localize a micro aerial vehicle (MAV) in GPS denied environments and without the usage of any known pattern. The method exploits the planar ground assumption and only uses the data provided by a monocular camera and an inertial measurement unit. It is based on a closed solution which provides the vehicle pose from a single camera image, once the roll and the pitch angles are obtained by the inertial measurements. Specifically, the vehicle position and attitude can uniquely be determined by having two point features. However, the precision is significantly improved by using three point features. The closed form solution makes the method very simple in terms of computational cost and therefore very suitable for real time implementation. Additionally, because of this closed solution, the method does not need any initialization. Results of experimentation show the effectiveness of the proposed approach

Cycle factorizations of cycle products

AbstractLet n and k1,k2,…,kn be integers with n > 1 and ki ⩾ 2 for 1 ⩽ i ⩽ n. We show that there exists a Cs-factorization of Πi=1n C2ki if and only if s = 2t with 2 ⩽ t ⩽ k1 + ··· + kn. We also settle the problem of cycle factorizations of the d-cube

Decomposing the real line into Borel sets closed under addition

We consider decompositions of the real line into pairwise disjoint Borel pieces so that each piece is closed under addition. How many pieces can there be? We prove among others that the number of pieces is either at most 3 or uncountable, and we show that it is undecidable in $ZFC$ and even in the theory $ZFC + \mathfrak{c} = \omega_2$ if the number of pieces can be uncountable but less than the continuum. We also investigate various versions: what happens if we drop the Borelness requirement, if we replace addition by multiplication, if the pieces are subgroups, if we partition $(0,\infty)$, and so on

Information System for Predicting Fisheries Outcomes Using Regression Algorithm Multiple Linear

Bireuen is one of the regencies in Aceh province which has quite a lot of potential for marine and fishery resources, both capture fisheries and aquaculture, because some areas in this district are coastal areas supported by several fish landing bases (PPI), namely PPI Kuala Jangka, Kuala Jeumpa, Peudada, Jeunip, Pandrah, and Bate Iliek which are supporting sectors of the regional economy. The importance of this research is so that the Department of Food Security, Maritime Affairs and Fisheries can estimate the catch of fish in the coming year so that it can be used in terms of policies to increase the fishery production sector. The method used in information systems research to predict fishery results Multiple Linear Regression Algorithm using two independent variables (X), namely, the number of motorized boats (X1), the number of rainy days (X2) and one dependent variable, namely the number of fish caught (Y). ). The steps taken in this research are data collection, calculation of each variable, completion of the elimination method, substitution to get constant values, coefficients and inserting constants and coefficients into the Multiple Linear Regression equation. Based on data obtained from 2016, 1017, 2018, 2019 and 2020 using the Multiple Linear Regression algorithm, the prediction results of the Tangka fishery in Bireuen Regency in 2021 are 12,813.88 tons

Profile of Cardiovascular Risk Factors and Mortality in Patients with Symptomatic Peripheral Arterial Disease

INTRODUCTION: The present study examines cardiovascular risk factor profiles and 24-month mortality in patients with symptomatic peripheral arterial disease. DESIGN STUDY: Prospective observational study including 75 consecutive patients with PAD (67 ± 9.7 years of age; 52 men and 23 women) hospitalized for planned peripheral vascular reconstruction. Doppler echocardiograms were performed before surgery in 54 cases. Univariate analyses were performed using Student's t-test or Fisher's exact test. Survival analysis at 24-month follow-up was performed using the Cox regression model and Kaplan-Meier method including age and chronic use of aspirin as covariates. Survival curves were compared using the log-rank test. RESULTS: Hypertension and smoking were the most frequent risk factors (52 cases and 51 cases, respectively), followed by diabetes (32 cases). Undertreated dyslipidemia was found in 26 cases. Fasting glycine levels (131 ± 69.1 mg/dl) were elevated in 29 cases. Myocardial hypertrophy was found in 18 out of 54 patients. Thirty-four patients had been treated with aspirin. Overall mortality over 24 months was 24% and was associated with age (HR: 0.064; CI95: 0.014-0.115; p=0.013) and lack of use of aspirin, as no deaths occurred among those using this drug (p<0.001). No association was found between cardiovascular death (11 cases) and the other risk factors. CONCLUSION: There is a high prevalence of uncontrolled (treated or untreated) cardiovascular risk factors in patients undergoing planned peripheral vascular reconstruction, and chronic use of aspirin is associated with reduced all-cause mortality in these patients

Le contrôle de gestion et la performance du secteur public: quelle interdépendance ?

L’amélioration de la performance et la rationalisation des ressources, autant d’objectifs à atteindre pour toute organisation qui cherche à se moderniser et s’adapter aux nouveaux défis de l’environnement (mondialisation, nouvelles technologies …), et aux attentes du citoyen qui est devenu une priorité. Dans ce cadre, différents outils et méthodes de contrôle de gestion ont été adoptée par les responsables des organisations publiques dans le but de renforcer la logique de l’efficacité, de l’efficience et de la performance, ce qui s’inscrit dans le cadre du modèle du "New public management" (NPM). Ce papier porte principalement sur la relation entre la mise en place d’un système de contrôle de gestion et l’amélioration de la performance&nbsp;du secteur public et présente d’une façon globale les différentes théories et études empiriques qui ont démontré le lien entre l’intégration des méthodes et outils du contrôle de gestion au sein des organisations publiques et l’atteinte de la performance de cette dernière, on mettra aussi l’accent sur la particularité du secteur public, les&nbsp; points de convergence et&nbsp;de&nbsp;divergence avec le secteur privé et les spécificités du contrôle de gestion dans les organisations publiques

Epstein-barr Virus Infection And Gastric Carcinoma In São Paulo, Brazil

Epstein-Barr virus (EBV) is a ubiquitous herpesvirus, and most people have serological evidence of previous viral infection at adult age. EBV is associated with infectious mononucleosis and human cancers, including some lymphomas and gastric carcinomas. Although EBV was first reported in lymphoepithelioma-like gastric carcinoma, the virus was also found in conventional adenocarcinomas. In the present study, 53 gastric carcinomas diagnosed in São Paulo State, Brazil, were evaluated for EBV infection by non-isotopic in situ hybridization with a biotinylated probe (Biotin-AGACACCGTCCTCACCACCC GGGACTTGTA) directed to the viral transcript EBER-I, which is actively expressed in EBV latently infected cells. EBV infection was found in 6 of 53 (11.32%) gastric carcinomas, mostly from male patients (66.7%), with a mean age of 59 years old. Most EBV-positive tumors were in gastric antrum. Two EBV-positive tumors (33.3%) were conventional adenocarcinomas, whereas four (66.7%) were classified as lymphoepithelioma-like carcinomas. EBV infection in gastric carcinomas was reported elsewhere in frequencies that range from 5.6% (Korea) up to 18% (Germany). In Brazil, a previous work found EBV infection in 4 of 80 (5%) gastric carcinomas, whereas another study found 4.7 and 11.2% of EBV-positive gastric carcinomas of Brazilians of Japanese origin or not, respectively. In the present study, the frequency of EBV-positive gastric carcinomas is similar to that reported in other series, and the clinicopathologic characteristics of these EBV-positive tumors are in agreement with the data in the literature.371117071712zur Hausen, H., Schulte-Holthausen, H., Klein, G., Henle, W., Henle, G., Clifford, P., Santesson, L., EBV DNA in biopsies of Burkitt tumors and
