A generalized patch AMR platform that uses cell centered or cell vertex solvers
No full textA patch adaptive mesh refinement (AMR) platform is presented. Presently two Navier-Stokes solvers are available within this platform : a MUSCL and DG solver (FLUX AMR) and a multi-species MUSCL solver (MAJIC) for reacting flows. The first solver is based on cell centered approaches of finite volume type, the second solver is based on a cell vertex and a time splitting method. The modifications of AMR treatments, especially those concerning the interpolation at fine-coarse boundaries are detailed. This platform is first tested on the subsonic flow over a deep cavity and secondly on the interaction of a steady planar shock with a H2-air circular diffusion flame
Euchondrus adwani Eike Neubert & Zuhair Amr 2016, n. sp.
No full textEuchondrus adwani n. sp. (Figure 1) Material: Holotype NMBE 539263; paratype NMBE 539264 /1. Type locality: Syria, surrounding of the monastery of Deir Moussa, 34.0219°N 36.8423°E, 1300 m a.s.l., 11.iii. 2010, leg. Adwan Shehab. *Corresponding author. Email: [email protected] © 2016 Taylor & Francis Measurements (holotype): Height = 11.04 mm; diameter = 4.13 mm; peristome height = 4.03 mm; peristome diameter = 2.97 mm; number of whorls = 8. Diagnosis. Euchondrus adwani n. sp. differs from the widespread E. septemdentatus by its conical shell (broadly oval in E. septemdentatus), its flat suture and teleoconch whorls (suture deeper, whorls much more rounded in E. septemdentatus), the heavy palatal labial callus (weaker in E. septemdentatus), the bar-like subangularis (weaker in E. septemdentatus), and the keeled last whorl (rounded in E. septemdentatus). Description: Shell solid, dextral, cylindrical, upper part cylindro-conical in outline; shell pale brownish to horny yellow coloured; 8 rather flat-sided teleoconch whorls, suture flat with a distinct white sutural thread; teleoconch smooth, glossy, last whorl with fine, straight and irregularly spaced striae; aperture subtriangular, peristome strongly thickened by a labial callus, moderately reflected, with a rich dentition (description clockwise): palatum with a small suturalis followed by a conical palatalis superior and a broad infrapalatalis with the latter two denticles placed on a thick callus; columellar side with a basalis and a straight columellaris; parietum with a strong and long parietalis, bordered by a small spiralis, subangularis large, bar-like, left side of the parietum with another small denticle at the attachment site of the peristome; last teleoconch whorl dorsally compressed forming a distinct blunt ridge (arrows); umbilicus slit-like open, periomphalum large, dish-like. Remarks: This species shows some superficial similarities with E. desertorum Rochanaburananda in Forcart, 1981 (Figure 2), which is endemic to the Negev Desert (Heller, 2009). Both species have a straight conical shell, but E. desertorum is considerably larger than E. adwani n. sp. and its aperture is rounded and not subtriangular. It also differs in the formation of the dentition: in E. desertorum, the infrapalatalis is bifid (simple in E. adwani), the spiralis is large and connected to the parietalis (small and disconnected in E. adwani), and the subangularis is weaker (very strong in E. adwani). The last whorl of E. adwani displays a distinct keel with an enlarged periomphalum, while in E. desertorum the dorsum is rounded, and the periomphalum is much smaller. Etymology: This species is named in honour of Dr. Adwan Shawabi, who was a keen collector of molluscs from Syria, and a personal friend, and who was killed in February 2015 in the Syrian civil war (Amr, 2015).Published as part of Eike Neubert & Zuhair Amr, 2016, On a new species of Euchondrus Boettger, 1883 from Syria (Pulmonata: Enidae), pp. 58-60 in Zoology in the Middle East 62 on pages 58-60, DOI: 10.1080/09397140.2015.1132564, http://zenodo.org/record/88703
AMR Sign - An Arthroscopic S-shaped Fold Signifying Adequate Medial Meniscus Repair
No full textIntroduction:
The preferred management of medial meniscus tears has notably moved from meniscectomies towards repair. With a higher volume of meniscal repairs being done all across the world with every passing day, the lack of an objective and definitive sign suggesting the adequacy of its repair is daunting. The purpose of our study was to introduce a unique and novel arthroscopic sign formed after adequate repair of the medial meniscus, the AMR (Adequacy of Medial meniscus Repair) sign. We hypothesised that it is not only the objective end point for repair, but can also form the indicator for excellent clinical, functional, and radiological outcome even in the long term.
Materials and methods:
This was a multicentric, prospective study initiated by the corresponding author, and the findings validated subsequently by the other authors. Overall, it included 804 patients of isolated medial meniscus tear operated with arthroscopic all-inside technique between January 2014 and December 2017. Patients were segregated into three groups based on whether an S-shaped curve in the free, inner edge of the medial meniscus sign was formed post-repair, lost after further tightening, or not formed upon subjective completion of repair. All the patients were followed-up and evaluated based of medial joint line tenderness, McMurray’s test for medial meniscus, IKDC score, WOMET score, and radiologically using an MRI at the terminal follow-up.
Results:
The mean terminal follow-up was 42.34±4.54 months. There was significant (p<0.01) improvement in all patients at the terminal follow-up post-surgery, irrespective of the group. The group in which AMR sign was formed and maintained showed a significantly better functional outcome on terminal follow-up as well as lower failure rates compared to the other two groups.
Conclusion:
AMR sign is an S-shaped fold at the inner, free edge of medial meniscus, formed after an adequate repair of isolated medial meniscus tear, as viewed on arthroscopy. It is an objective sign denoting regained integrity of the collagen architecture of the medial meniscus following repair. It is also a reliable indicator of excellent long term functional, clinical, and radiological outcome and also lower failure rates in patients after arthroscopic medial meniscus repair
Penafsiran Ibnu 'Asyur tentang ayat perintah (Amr) pada surat Al-Hajj dalam tafsir At-Tahrir Wa At-Tanwir
No full textThe command word in the Qur'an (amr) is instructive, which contains that the command must be carried out. The thing that needs to be known is that the command word has other meanings than is mandatory, this is also called majazi. to find out, the author uses balaghi-style interpretations, namely at-Tahrir wa at-Tanwir by Thahir Ibnu ‘Asyur which is thick with language discussion. This study only discusses amr in Surah Al-Hajj. Because Surah Al-Hajj has special features such as there are verses about the Hajj as well as the name of the surah. This study aims to determine the form and type of amr contained in Surah Al-Hajj and its implications in the interpretation of Ibn ‘Asyur. Answering the subject matter, researchers used a descriptive qualitative method. To find out the form of amr found in Surah Al-Hajj, the author first collects verses that have command words in tafsir at-Tahrir wa at-Tanwir. Then classify amr based on the form and explain the type of amr and its implications in the interpretation of Ibn ‘Asyur. The results of this study indicate that amr in Surah Al-Hajj has two forms of siya> gh al-amr, namely fi'il amr and la> m al-amr which found 18 verses of command in Surah Al-Hajj these are divided into two types of amr first , that wajib found in QSAl-Hajj [22]: 1, 26, 27,28,29, 30, 34, 36, 37, 49, 67, 77 and 78. And second, majazi is found in QSAl-Hajj [22]: 15, 22, 24, 36 and 73. The meaning of majazi found among others is iha> nah}, irsya> d, ibah} ah, ta'ji> z, and ta'ji> b. And the type of amr implications for the interpretation of Ibn ‘Asyur are the prevailing command wants results shortly, the order applies continuously, the order applies if there are conditions, and the order applies at the right time
ForestClaw: Hybrid forest-of-octrees AMR for hyperbolic conservation laws
No full textWe present a new hybrid paradigm for parallel adaptive mesh refinement (AMR) that combines the scalability and lightweight architecture of tree-based AMR with the computational efficiency of patch-based solvers for hyperbolic conservation laws. The key idea is to interpret each leaf of the AMR hierarchy as one uniform compute patch in Rd with md degrees of freedom, where m is customarily between 8 and 32. Thus, computation on each patch can be optimized for speed, while we inherit the flexibility of adaptive meshes. In our work we choose to integrate with the p4est AMR library since it allows us to compose the mesh from multiple mapped octrees and enables the cubed sphere and other nontrivial multiblock geometries. We describe aspects of the parallel implementation and close with scalings for both MPI-only and OpenMP/MPI hybrid runs, where the largest MPI run executes on 16,384 CPU cores. © 2014 The authors and IOS Press.We would like to thank the Texas Advanced Computing Center (TACC) for access to the Stampede supercomputer under allocations TG-DPP130002 and TG-ASC130001 granted by the NSF XSEDE program.

How is corporate social responsibility adopted by managers? The contribution of ethnography
No full textThis short paper details the ethnographic research processes of access and rapport that are outcomes of PhD research on the topic of corporate social responsibility (CSR). The reason for detailing these processes is twofold. Firstly, I argue that the contribution of ethnography to CSR research is simply the question: how is CSR adopted by managers? Secondly, an ethnographer must convince in their interpretation that the research is valid and useful to the subject of research. In this particular case, that the method of research and how it is communicated are significant for the better understanding of CSR. This paper inductively concludes that one (or the first) contribution of ethnography to CSR is simply that the causes of individual action in the 'institutional and structural order of society' (Webb, 2006 p.4) are over-looked and under-researched
Adapting authoritarianism: institutions and co-optation in Egypt and Syria
No full textThis PhD thesis compares Egypt and Syria’s authoritarian political systems. While the tendency in social science political research treats Egypt and Syria as similarly authoritarian, this research emphasizes differences between the two systems with special reference to institutions and co-optation. Rather than reducibly understanding Egypt and Syria as sharing similar histories, institutional arrangements, or ascribing to the oft-repeated convention that “Syria is Egypt but 10 years behind,” this thesis focuses on how events and individual histories shaped each states current institutional strengthens and weaknesses. Specifically, it explains the how varying institutional politicization or de-politicization affects each state’s capabilities for co-opting elite and non-elite individuals.
Beginning with a theoretical framework that considers the limited utility of democratization and transition theoretical approaches, the work underscores the persistence and durability of authoritarianism. Chapter two details the politicized institutional divergence between Egypt and Syria that began in the 1970s. Chapter three and four examines how institutional politicization or de-politicization affects elite and non-elite individual co-optation in Egypt and Syria. Chapter five discusses the study’s general conclusions and theoretical implications.
This thesis’s argument is that Egypt and Syria co-opt elites and non-elites differently because of the varying degrees of institutional politicization in each governance system. Rather than view one country as more politically developed than the other, this work argues that Syria’s political institutions are more politicized than their Egyptian counterparts. Syria’s political arena is, thus, described as politicized-patrimonialism. Syria’s politicized-patrimonial arena produces uneven co-optation of elites and non-elites as they are diffused through competing institutions. Conversely, the Egyptian political arena remains highly personalized as weak institutions and individuals are manipulated and molded according to the president’s ruling clique. This is referred to as personalized-patrimonialism. As a consequence, Egypt’s political establishment demonstrates more flexibility in ad hoc altering and adapting its arena depending on the emergence of crises.
This study’s theoretical implications suggest that, contrary to modernization and democratization theory’s adage that institutions lead to a political development, politicized institutions within a patrimonial order actually hinder regime adaptation because consensus is harder to achieve and maintain. It is within this context that Egypt’s de-politicized institutional framework advantages its top political elite. In this reading of Egyptian and Syrian politics, Egypt’s personalized political arena is more adaptable than Syria’s. These conclusions do not indicate that political reform is a process underway in either state
Patterns of antimicrobial resistance among enteric bacteria found in multi-site group-level cohorts of humans and swine
No full textThe prevalence of antimicrobial resistance (AMR) phenotypes and genotypic
characteristics (Class 1 integron and AMR gene cassettes) in commensal Escherichia coli
(EC) and vancomycin resistant Enterococcus faecium (EF) isolated from humans and
swine in a semi-closed, integrated farrow-to-fork population were evaluated in a crosssectional
study. Our objective was to establish baseline antimicrobial resistance patterns
and to evaluate the stability of isolate recovery phenotype within multiple grab samples per
collection day and over multiple biweekly samples collected during a period of several
months. This data will serve as a baseline for continuing longitudinal studies within the
population. These continuing studies should produce the first comprehensive
epidemiological data to document the transmission dynamics of antimicrobial resistance in
the farrow-to-fork continuum. Outcome variables assessed included: phenotypic resistance
in EC, pan-susceptibility, multi-resistance and genotypic resistance. Potential predictor
variables included: 1) host species, 2) unit, 3) unit type, 4) housing cohort by species, and
5) time of day. There were significant differences (p<0.05) between host species with
swine at higher odds for both single and multiple resistance. There were also differences
in resistance based on unit location, unit-type, and housing cohort within both humans and
swine. Our study found no significant differences (p>0.05) in resistance between swine
workers and non-swine workers with the sole exception of resistance to cephalothin, with
non-swine workers at 1.89 higher odds for resistance (p=0.02). A total of 17 VRE were
isolated from human wastewater samples, and to the author��s knowledge these represent
the first environmentally isolated VRE in the U.S. Several unique multi-resistance
phenotypes were observed and future evaluation of AMR phenotype in continuing
longitudinal studies provides a unique opportunity to study phenotypic patterns and
dissemination through the study population
