Comparative study between lightweight poliglecaprone meshes versus traditional heavyweight polypropylene meshes for the repair of inguinal hernia
Authors: El-Shafey Mohammad H , Ramadan Muhammad 
Published: October 2019

Introduction
The ideal outcome of inguinal hernia surgery is to provide a repair that is free from recurrence, pain and infection with minimal scarring and with improvement in patient's quality of life.

Aim of the work
Is to compare lightweight poliglecaprone (Ultrapropolypropylene/Monocryl), UltraPro™ mesh with the standard heavyweight polypropylene mesh in tension free Lichtenstein inguinal hernia repair.

Patients and methods
The current study included 200 patients complained of uncomplicated inguinal hernia and they were randomized into two groups according to the type of mesh used in tension free Lichtenstein inguinal hernia repair. Group I, 100 patients received the standard polypropylene mesh. Group II, 100 patients received light weight UltraPro™ mesh, using sutures for their fixation.

Results
The UltraPro™ (LWM) mesh proved to be as safe and effective as the standard (HWM) prolene mesh in repair of uncomplicated inguinal hernia. There was no difference between the two groups as regard to the technical difficulties, operative complications and surgeons were equally satisfied. There was more incidence of chronic pain with prolene mesh (25%) compared to (zero%) with UltraPro™ mesh. The mesh fixation time and the overall operative time were shorter with UltraPro™ mesh.

Conclusion
The shorter operative time and the no-need to use analgesics could partially compensate the higher cost of UltraPro™ mesh in the absence of other economic factors such as the duration of patient improvement and return to work.

Published: October 2019

The main objective of this paper is to provide a theory for computing the Hochschild cohomology of algebras arising from a linear category with finitely many objects and zero compositions. For this purpose, we consider such a category using an ad hoc quiver

Q

, with an algebra associated to each vertex and a bimodule to each arrow. The computation relies on cohomological functors that we introduce, and on the combinatorics of the quiver. One point extensions are occurrences of this situation, and Happel’s long exact sequence is a particular case of the long exact sequence of cohomology that we obtain via the study of trajectories of the quiver. We introduce cohomology along paths, and we compute it under suitable Tor vanishing hypotheses. The cup product on Hochschild cohomology enables us to describe the connecting homomorphism of the long exact sequence.

Algebras arising from a linear category where the quiver is the round trip one, provide square matrix algebras which have two algebras on the diagonal and two bimodules on the corners. If the bimodules are projective, we show that five-terms exact sequences arise. If the bimodules are free of rank one, we provide a complete computation of the Hochschild cohomology. On the other hand, if the corner bimodules are projective without producing new cycles, Hochschild cohomology in large enough degrees is that of the product of the algebras on the diagonal.
As a by-product, we obtain some families of bound quiver algebras which are of infinite global dimension, and have Hochschild cohomology zero in large enough degrees.

Published: October 2019

Abstract. KOERI has a long history of earthquake seismology,
beginning its observations right after the devastating earthquake on 10 July 1894 in Istanbul, by deploying the first seismograph in the region.
Naturally, its seismic network and earthquake catalog evolved since that
time, in harmony with the progress in the science of seismology. Currently,
the seismic network consists of 242 stations that record approximately 1500
earthquakes per month during periods of regular seismicity. Magnitude is one
of the most critical parameters in determining the size of an earthquake,
especially in seismic hazard assessment studies. The objective of this study
is to homogenize the magnitudes of the KOERI catalog between 2008 and 2018.
For this aim, we computed the Magnitude of Completeness (Mc) for two
different time periods between 2008–2011 and 2012–2018 by taking into
account the duration magnitude (Md) and local magnitude (Ml), where these
parameters might not be available jointly for the both time periods
considered. As a result, we present a relationship of Md and Ml magnitudes
derived from and applicable to KOERI's earthquake catalogs.
Inundation analysis of metro systems with the storm water management model incorporated into a geographical information system: a case study in Shanghai
Authors: Lyu Hai-Min , Shen Shui-Long , Yang Jun , Yin Zhen-Yu 
Published: October 2019

Abstract. This study presents an integrated approach to evaluate inundation
risks, in which an algorithm is proposed to integrate the storm water
management model (SWMM) into a geographical information system (GIS). The
proposed algorithm simulates the flood inundation of overland flows and in
metro stations for each designed scenario. It involves the following stages:
(i) determination of the grid location and spreading coefficient and (ii) an
iterative calculation of the spreading process. In addition, an equation is
proposed to calculate the inundation around a metro station and to predict
the potential inundation risks of the metro system. The proposed method is
applied to simulate the inundation risk of the metro system in the urban
centre of Shanghai under 50-year, 100-year, and 500-year rainfall
intensities. Both inundation extent and depth are obtained and the proposed
method is validated with records of historical floods. The results
demonstrate that in the case of a 500-year rainfall intensity, the inundated
area with a water depth excess of 300 mm covers up to 5.16 km2. In
addition, four metro stations are inundated to a depth of over 300 mm.

A arborização urbana é entendida como toda cobertura de vegetação arbórea presente nas cidades, a mesma é uma grande influenciadora na qualidade de vida da população. Porém é necessário um bom planejamento e monitoramento das espécies inseridas no ambiente urbano, de modo que se tenha os benefícios esperados da arborização. O objetivo do trabalho foi identificar as implicações da utilização do Ficus spp. em 4 bairros e 11 praças do município de Santarém, Pará. Foi realizado um inventário total destas áreas, considerando somente os indivíduos com altura igual ou superior a 1,5m. Considerou-se uma espécie exótica por não ser de formação originária do Brasil. Foram calculadas a Frequência absoluta (FA) e Frequência relativa (FR) da espécie Ficus spp. em relação ao número total de indivíduos inventariados. Para esse estudo foram totalizados 1416 indivíduos, dentre eles, 115 são Ficus spp. no momento do levantamento, 93,91% dos indivíduos arbóreos estavam em estado vegetativo. Em relação a sanidade da copa das espécimes encontradas, 79,13% possui copa saudável e sem problemas. Dentre as árvores amostradas, aproximadamente 25% da amostra necessita de algum tipo de manejo, seja poda, substituição ou remoção da árvore. Essa espécie exótica não é indicada para arborização urbana, pois tem causado conflitos com calçadas, tubulações e rede elétrica, devido terem raízes agressivas e crescimento rápido.

Authors: NISSEN Katrine Dueholm , Christiansen Charlotte Dahl , Harder Louis , Jessen Marie , Mackenhauer Julie 
Published: October 2019

Baggrund:
I 2018 blev akutmedicin et selvstændigt speciale (1). Målbeskrivelsen er udarbejdet af sundhedsstyrelsen (SST), Dansk Selskab for Akutmedicin (DASEM) og en række andre specialer. Dernæst er kompetencekortene til de 9 kompetencer udarbejdet af DASEM (2). De uddannelsesansvarlige overlæger har lokalt udarbejdet uddannelsesprogrammer, som definerer hvordan de 9 kompetencer opnås i hver enkelt akutafdeling. Andre specialer har god erfaring med at supplerer med specifikke færdighedskort som fx kan benyttes til at superviser praktiske kliniske procedurer.

Formål:
Yngre Danske Akutmedicinere (YDAM) afviklede i marts 2019 første nationale uddannelsesdag. Formålet med dagen var at erfaringsudveksle på tværs af hospitaler samt samle input til DASEM med henblik på revision af målbeskrivelsen, kompetencekort samt udarbejdelse af nye færdighedskort.

Metode:
Der blev afholdt et endags seminar for alle uddannelseslæger og uddannelsesansvarlige overlæger i akutmedicin. Dagen bestod af gruppearbejde, hvor målbeskrivelsen, kompetencekort og uddannelsesprogrammer blev gennemgået kritisk og der blev opstillet forslag til evt. forbedringstiltag.

Resultat:
Der var 36 deltagere på uddannelsesdagen, heraf 9 overlæger og 27 uddannelseslæger. Der var bred deltagelse på dagen med uddannelseslæger fra alle regioner men ikke alle 21 akutsygehuse. Alle kom med input til forbedring af målbeskrivelse og kompetencekort. Dette blev samlet i et fælles dokument. Der blev opstillet 14 forslag til nye færdighedskort.

Konklusion:
Uddannelsesdagen klarlagde at der blandt yngre læger og uddannelsesansvarlige overlæger er et ønske om at uddannelsesmaterialet opdateres for at forbedre den akutmedicinske introduktionsuddannelse. For at øge det faglige niveau, ønskede deltagerne bl.a opdatering af kompetencekort samt nye færdighedskort. De akutmedicinske læger som har grundlagt DK-AKUT, er allerede i gang med dette arbejde og man bør i samarbejde med dem opdaterer kompetencekort og færdighedskort efter international standard.

Objective: This study aims to estimate the annual doses for personnel categories following their exposure to ionizing radiation during their occupation in the external radiotherapy department of the Center of Oncology and Hematology (COH) at Mohammed VI Hospital in Marrakech.
Materials and Methods: Operational dosimeters PACK MGP DMC 3000 were used to measure the dose rates around the machines operating with ionizing radiation. In order to assess the reliability of the measurements made by these dosimeters, they were checked against measurements made at the same position by the Inspector detector. The annual effective dose was calculated by multiplying the average dose rate measured during a procedure by the overall treatment time throughout a year.
Results: Regarding the reliability check of the measuring instrument, the recorded error is between 2 and 10% with an average of 7%. For personnel category A, the measured dose rate ranges from 0.066 to 0.083 µSv/h, with an average value of 0.075 µSv/h. For category B, it varies between 0.066 and 0.083 µSv, with an average value of 0.092 µSv/h. It is 0.074 µSv/h for category C. The annual dose for category A ranges from 0.089 to 0.113 mSv/year, with an average value of 0.101 mSv/year. For category B, it varies between 0.089 and 0.113 mSv/year, with an average value of 0.100 mSv/year. It is 0.100mSv/year for category C.
Conclusion: The annual effective doses to personnel categories, assessed by this study, are very low compared to the regulatory standards set by the International Commission on Radiological Protection (ICRP). As a result, workers benefit from good radiation protection conditions within the Center of Oncology and Hematology at Mohammed VI Hospital in Marrakech.

Cephalometry deals with the measurement of the head or radiological specimen of the head. Sella turcica is an important anatomical structure located in the middle cranial fossa, housing the pituitary gland. Various shapes and sizes of the sellae turcica have been reported. However, in this study, using computerized tomographic (CT) scans, one hundred and seventy-five (175) scans were analyzed using Radiant version 4.2 for determination of sizes and shapes of the sella. Average dimensions from the study include length (12.4mm), A-P diameter (14.1 m), depth (9.6 mm) and transverse diameter (13.8mm). Shapes were classified as being round (56.6%), oval (32%) and flat (11.4%). Males tend to have higher sella sizes than females and there are statistically significant differences between them especially in respect to A-P diameter and length parameters. Also, there is a statistically significant relationship between age groups in terms of A-P diameter and depth of the sella turcica. However, there is no correlation between age and shapes found in the study.

Published: October 2019

Aims: The objective is to approach the use of the flour of the mesquite grains in restructured hamburger meat product formulations.
Introduction: The mesquite seed is a by product of great nutritional value and little use in large scale for food purposes, being considered, also, discarding raw material in the processing of the mesquite pod. The seeds represent an agroindustrial byproduct with broad technological and nutritional potential, with some applications already tested and widespread in the food and environmental sector. The high sugar content associated with the high levels of nitrogen in the mesquite tree pods favours the biochemical processes and enables the production technology of alcohol, spirits, liquor, wine, honey, enzymes, acids, gums, vinegar, sugars and even a substitute drink for coffee. In some Andean countries, other beverages such as lodge, chicha, etole and algarobina (a type of stomach and aphrodisiac fortifier), flour, biscuit and cookies are made. The physicochemical characteristics of the hamburger should contain a maximum fat content of 23.0%, a minimum of 15% protein, 3% total carbohydrates and calcium content (maximum dry basis) 0,1% in raw hamburger and 0.45% cooked hamburger.
Conclusion: The use of resources to reduce the disadvantages related to the addition of fibre in meat products should be studied in order to obtain the benefits of this addition without compromising the acceptability and quality of the final product, besides allowing a greater addition of mesquite seed in order to achieve the requirements for a functional product.

Adequate staff-students ratio (SSR) is one of the important National Universities Commission (NUC) prescribed criteria to be implemented in manpower planning by Universities in Nigeria. Forecasting manpower requirement has been used for economic planners and even the academic sector. In other to avoid imbalance, the manpower requirement is very vital in determining the desired output in a system. This study is aimed at predicting the adequate manpower required in a unit of an academic institution. Manpower related data of the Mechanical Engineering Department, Federal University of Technology, Akure Nigeria were collected. The data collected includes manpower capacity and students population over a period of thirteen consecutive years. The regression analysis based model was formulated and applied to analyze the collected data. Based on the analyzed data, trends of , , and are obtained respectively for the student's population size, lecturers and technical staff requirements, where and X are economic indicators. The obtained trends equations were then subsequently applied to compute SSRs and recommendations were made. The developed model was implemented in a computer software, using the Visual Basic programming language, in order to facilitate its solution procedure. The outcome of this study will aid the management of the institution in effective manpower determination and students number projection in future years. This will also assist the institution to plan for effective SSR based on the recommendation of NUC.

To ensure the stability of the bottom under the floating bridges according to the worst conditions, our study aims to determine the height and width and bearing the floating bridge to ensure the safety of origin with a high security factor. Our study determines the amount of damage under the floating bridge to be treated by a treatment method. We have used a practical model for a water channel and standard dimensions cut by the floating bridge connecting the two ends of the channel and when studying the erosion under the floating bridges and the possibility of maintaining the floating bridges without damage to the structure and perimeter of the bridge (bridge width, maximum load, bridge height, water depth in the channel with a factor Security This study examines the effect of floating bridges on the bottom by designing a model of a channel with a floating bridge and selecting a variable earth and sand floor. We conducted one hundred and sixty-eight experiments to examine the five variables (water depth in the channel, bridge width, loads on the bridge, soil type) Bottom, flow). We observed the effect of these five variables on topography of the bottom of the floating bridge. Experiments were conducted without a bridge and we observed erosion after laying the bridge, we noticed the erosion and sediment that occurred before and below and after the floating bridge and the effect of the bridge on it. We observed the type of positive and inverse relations between the variables mentioned. We took the loads on the bridge, the width of the bridge, the depth of the water and the drainage with a safety factor, as well as ensuring that the appearance of the channel and maintain the geometry of the channel. We put floating loads on the floating bridge to see a load. We used several models to view the floating bridge and made the water depth in the channel change more than once. We also made three different discharges. Finally, we used two types of soil and we recorded the durability and the worst conditions. The effect discharge, by (100% .64%, 45%) The velocity in the sandy soil changes (100%, 42%,38%) and the velocity in clay soil changes (100%,59%,41%) As well as change the width of the bridge by (100%, 85%,71%)velocity changes by (80%,82%,100%) for sandy soil and the ratio of clay soil to (90%,95%,100%) As well as weight change by (100% ,83%,66%)the rate of velocity in the sandy soil to (100%,78%,61%) also change the velocity in clay soils to (100%,68%,62%) as well as depth change (100%,87%,75%)The speed in the sandy soil changes to (50%,75%,100%) and also changes in clay soils by (71%,78%,100%) Thus, we have a knowledge of the rates of change and the effect of each variable on velocity.
Therefore, we can draw up a plan to address erosion and sedimentation in the watercourse. Moreover, identify the expected challenges of (overload, flooding, deterioration, foot and aging as well as the structural strength of the bridge gradually decreasing with the foot.

AbstractThe Streptophyta include unicellular and multicellular charophyte green algae and land plants. Colonization of the terrestrial habitat by land plants is a major evolutionary event that has transformed the planet. So far, lack of genome information on unicellular charophyte algae hinders the understanding of the origin and the evolution from unicellular to multicellular life in Streptophyta. This work reports the high‐quality reference genome and transcriptome of Mesostigma viride, a single‐celled charophyte alga with a position at the base of Streptophyta. There are abundant segmental duplications and transposable elements in M. viride, which contribute to a relatively large genome with high gene content compared to other algae and early diverging land plants. This work identifies the origin of genetic tools that multicellular Streptophyta have inherited and key genetic innovations required for the evolution of land plants from unicellular aquatic ancestors. The findings shed light on the age‐old questions of the evolution of multicellularity and the origin of land plants.
