Cassibile revisited: rock-cut monuments and the configuration of Late Bronze Age and Iron Age sites in southeast Sicily
Authors: Leighton Robert
Published: May 2016

Die prähistorische Nekropole von Cassibile im Südosten der Insel Sizilien gilt als bedeutender regionaler Fundort für die späte Bronze- und Eisenzeit Italiens (ca. 1300 bis 700 v. Chr.). Die Region wird allgemein als ein wichtiges Bevölkerungszentrum und Sitz einer Herrschaft angesehen, die noch vor der griechischen Kolonisation im 8. Jh. v. Chr. einen prägenden Einfluss auf umfangreiche Gebiete ausübte. Bekannt ist der Fundplatz vor allem aufgrund der in den Jahren 1898 und 1927 von Paolo Orsi durchgeführten Ausgrabungen und der weit mehr als 1000 in den Fels gehauene Grabkammern, die sich über eine Fläche von etwa 6 km
Twinning in chemical crystallography – a practical guide
Authors: Herbst-Irmer Regine
Published: May 2016

A non-negliglible percentage of crystal structures in chemical crystallography are derived from twinned crystals. The treatment of these data is dependent on the type of twinning. Twins by strict, pseudo or reticular merohedry may hamper space group determination and structure solution, while non-merohedral twins mainly hinder the data integration process. One structure determination of each type is described in detail. CsCp*Py (1) crystallizes in space group P65, mimicking 6/mmm symmetry by merohedral twinning. The data of IPr · AlI3 (2) (IPr=1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) simulate mmm symmetry although the true space group is P21/n. The crystals of K[Au(CN)2] (3) are obverse/reverse twins. [Cu3(dppaO2)2((OSiMe2)2O)2(thf)2] (4) (ddpaO2=bis(diphenylphosphoryl)amine) crystallizes in space group P21/n and is an example of a non-merohedral twin.
The Hygroscopy of Amino Acid Ionic Liquids in Aqueous Solution: a Quantum Chemistry Study
Authors: Zhu Xueying , Ai Hongqi
Published: May 2016

Due to many remarkable advantages, such as biodegradability, low cost, chiral property, no toxicity, and excellent
solution property, amino acid ionic liquids (AAILs) have received more and more attention and recognition in many chemical
and environmental engineering fields. The intervention of water would significantly influence their properties.

To understand this effect, the binary systems of water with amino acid-based anion A (A = glycine (Gly−),
alanine (Ala−), valine (Val−), and leucine (Leu−)),
1-alkyl(C1–4)-3-methyl imidazolium-based cation B (B = [mmim]+, [emim]+, [pmim]+,
and [bmim]+), and [bmim]Gly ion pair were systematically studied using density functional theory. For either
A-water or B-water system, the shorter the alkyl chain is, the stronger the anion-water or cation-water interaction is and
greater the stability of the system is. The anion-water or cation-water system was discussed by infrared spectroscopy and
natural bond orbital analises. In [bmim]Gly-water, both the anion and the cation are important for the stability of
[bmim]Gly-water system, and the former ion is more significant than the latter on the properties of AAIL in aqueous
solution. The effects on the properties of AAIL in aqueous solution were predicted. This work can provide theoretical
basis for improvement of properties, design and application of AAILs.

Published: May 2016

Diverse biological applications of triazole molecules, makes study of these compounds intriguing. Since, the solvent
effect causes different behavior in these compounds, a quantitative study of solvent effects on photo-physical properties
of two triazole compounds, with similar molecular skeleton and various substituent groups on triazole ring were studied,
at room temperature. The solute's photo-physical behavior strongly depends on the solute and solvent's nature, along with
the solvent-solute interactions. In order to understand the effect of intermolecular interactions on spectral behaviors of
these materials, and to conceive the nature and extend of solvent-solute interactions, the spectral variations were
analyzed via the linear solvation energy relationships concept, suggested by Kamlet and Taft. In addition, by means of
solvatochromic method, ground and excited states dipole moments as well as dipole moment variations, from ground to
excited states, were calculated, in different media.

The objectives of this research were to study the effect of glycerol and chitosan addition toward biodegradability of cellulose based rice waste water, the effect of biodegradation time toward mass lost and biodegradability, and determine functional group and crystalinity of the highest biodegradability composite. Bacterial celluloses were prepared from 100 mL rice waste water that fermented by Acetobacter xylinum for 7 days with addition of glycerol (for Cellulose-Glycerol and Cellulose-Glycerol-Chitosan). Then, bacterial celluloses were immersed in chitosan solution (for Cellulose-Chitosan and Cellulose-Glycerol-Chitosan). The water in bacterial cellulose and its composites was removed by heating, then deposited silver nanoparticle  on the bacterial cellulose and its composite. The silver nanoparticles were prepared by chemical reduction with using AgNO3 solution, trisodium citric as reducing agent, and gelatin as stabilizer. The silver nanoparticle was deposited into bacterial cellulose and its composites film by immersing method. After that, the bacterial cellulose and its composites were biodegradated by soil burrial test method for 14 days. Then, cellulose with the highest biodegradability was characterized by ATR-FTIR and XRD. The silver nanoparticle formation was showed by UV-Vis spectrum with peak in the 418.8 nm area. The glycerol addition can increase biodegradability, whereas the chitosan addition can decrease biodegradability. The increasing of biodegradation time, mass lost increased but the biodegradability decreased. After biodegradation, intensity of pyran cyclic in cellulose-glycerol which is deposited Ag (SG + Ag)  decreased, but crystallinity of it increased.

Interstitial Lung Disease in Children Younger Than 2 Years
Authors: Spagnolo Paolo , Bush Andrew
Published: May 2016

Childhood interstitial lung disease (chILD) represents a highly heterogeneous group of rare disorders associated with substantial morbidity and mortality. Although our understanding of chILD remains limited, important advances have recently been made, the most important being probably the appreciation that disorders that present in early life are distinct from those occurring in older children and adults, albeit with some overlap. chILD manifests with diffuse pulmonary infiltrates and nonspecific respiratory signs and symptoms, making exclusion of common conditions presenting in a similar fashion an essential preliminary step. Subsequently, a systematic approach to diagnosis includes a careful history and physical examination, computed tomography of the chest, and some or all of bronchoscopy with bronchoalveolar lavage, genetic testing, and if diagnostic uncertainty persists, lung biopsy. This review focuses on chILD presenting in infants younger than 2 years of age and discusses recent advances in the classification, diagnostic approach, and management of chILD in this age range. We describe novel genetic entities, along with initiatives that aim at collecting clinical data and biologic samples from carefully characterized patients in a prospective and standardized fashion. Early referral to expert centers and timely diagnosis may have important implications for patient management and prognosis, but effective therapies are often lacking. Following massive efforts, international collaborations among the key stakeholders are finally starting to be in place. These have allowed the setting up and conducting of the first randomized controlled trial of therapeutic interventions in patients with chILD.

Quince familias de papa (840 genotipos) provenientes de cruzas inter-específicas entre especies de Solanum stenotomum, S. goniocalyx y S. phureja fueron genotipadas, con el objetivo de asociar  seis marcadores moleculares (GP94, HC, Nl25, Gro 1-4, RYSC3 y CP60) con genes mayores de resistencia para tizón tardío (Phytophthora infestans), verruga (Synchytrium endobioticum), nematodo - quiste (Globodera pallida y G. rostochiensis) y virus PVY y PVX. Los resultados mostraron que cinco de los marcadores aplicados fueron polimórficos y amplificaron en más del 80% de las familias. El marcador RYSC3 que co-localiza con el gen Ry no amplificó en ninguna de las familias evaluadas. La familia 8 amplificó la banda para tres marcadores (CP60, GP94 y NL25) en la totalidad de sus clones. La prueba de χsup2 se utilizó para determinar el ajuste de las proporciones de segregación de cada familia para cada marcador y genotipar los progenitores. Nueve caracteres agronómicos y morfológicos fueron evaluados en la cosecha. Mediante agrupamiento cluster fueron seleccionados 107 clones con resistencia a PVX, P. infestans, G. rostochiensis y S. endobioticum, alto rendimiento y volumen de tubérculos, elevado número de tubérculos y ojos superficiales. Sobre la base de estos resultados, aspectos prácticos para la aplicación eficiente de la selección asistida por marcadores moleculares son discutidos en este artículo.

Primary Cleft Lip and Palate Repair in Assam, India: Does Preoperative Anthropometric Analysis Help Identify Patients with Increased Surgical Risk in a Clinically Prescreened Population?
Authors: Jerome Mairin A. , Gillenwater Justin , Laub Donald R. , Osler Turner , Allan Anna Y. , Restrepo Carolina , Campbell Alex
Published: May 2016

Objective

To compare anthropometric z-scores with incidence of post-operative complications for patients undergoing primary cleft lip or palate repair.

Design

This was a retrospective observational analysis of patients from a surgical center in Assam, India, and includes a cohort from a single surgical mission completed before the opening of the center.

Setting

Patients included in the study underwent surgery during an Operation Smile mission before the opening of Operation Smile's Guwahati Comprehensive Cleft Care Center in Guwahati, India. The remaining cohort received treatment at the center. All patients received preoperative assessment and screening; surgery; and postoperative care, education, and follow-up.

Patients, Participants

Our sample size included 1941 patients and consisted of all patients with complete information in the database who returned for follow-up after receiving primary cleft lip repair or primary cleft palate repair between January 2011 and April 2013.

Interventions

Preoperative anthropometric measurements.

Main Outcome Measure(s)

Postoperative complications.

Results

Anthropometric z-scores were not a significant predictor of adverse surgical outcomes in the group analyzed. Palate surgery had increased risk of complication versus lip repair, with an overall odds ratio of 5.66 ( P < .001) for all patients aged 3 to 228 months.

Conclusions

Anthropometric z-scores were not correlated with increased risk of surgical complications, possibly because patients were well screened for malnutrition before surgery at this center. Primary palate repair is associated with an approximate fivefold increased risk of developing postoperative complication(s) compared with primary lip repair.

Published: May 2016

Van der Woude syndrome (VWS) is a rare autosomal dominant genetic disorder characterized by orofacial clefting and lip pits. Mutations in the transcription factor interferon regulatory factor 6 gene ( IRF6) have been identified in individuals with VWS. We performed direct sequencing of the gene for molecular investigation of a proband with Bangladeshi-Malay ancestry. A novel transition mutation (c.113T>C), which resulted in an amino acid substitution (p.Ile38Thr) in the deoxyribonucleic acid-binding domain was detected. Testing of family members showed that the mutation segregated with the VWS phenotype for members of her immediate family. Although there is some phenotypic variability, all of the affected members are of the female gender.
Meta-Analysis of Crop and Weed Growth Responses to Arbuscular Mycorrhizal Fungi: Implications for Integrated Weed Management
Authors: Li Meng , Jordan Nicholas R. , Koide Roger T. , Yannarell Anthony C. , Davis Adam S.
Published: May 2016

Integrated weed management (IWM) relies upon multiple chemical, physical, or biological weed management techniques to achieve an acceptable level of weed control. Agents that selectively suppress weeds but not crops and that can be manipulated in agriculture will be promising components for inclusion in IWM. We used a meta-analytic approach to investigate the potential of arbuscular mycorrhizal fungi (AMF) to contribute to IWM. We quantified the effect of crop and weed host status (strong and weak AMF hosts are divided in this study by a 10% root length colonization threshold), AMF diversity (single vs. mixed), and soil N and P fertility management on plant mycorrhizal growth responses (MGRs). Our results indicated that weak host weeds had consistently lower MGRs than strong host crops in both controlled and field conditions. Moreover, these differences in MGRs between weak host weeds and strong host crops were more pronounced under mixed AMF inoculum and low N and P nutrient availability. In contrast, MGR of strong host weeds was not different from strong host crops in general. However, we observed a wide range of MGRs among strong host weeds, some of which had much lower MGRs than strong host crops. In addition, in the presence of N and P fertilizers, strong host crops had a stronger positive response to AMF than strong host weeds. Thus, our meta-analysis indicates that AMF have potential to contribute to weed control by direct and indirect pathways: directly suppress weak host weeds, and indirectly suppress some strong host weeds mediating by competitive effects exerted by strong host crops. We suggest that management practices affecting AMF diversity and crop and weed mycorrhizal responses could be chosen to improve the contribution of AMF to IWM. Better understanding is needed of crop–weed–AMF interactions and management practices that enhance this form of weed management.
Quantitative characterisation of absorption capacity and dosage of SAP in cement paste
Authors: Li Ming , Wang Yu-jiang , Wang Wen-bin , Tian Qian , Liu Jia-ping
Published: May 2016

The internal curing effect of superabsorbent polymers (SAPs) on high- and ultra-high-performance concrete has been widely acknowledged. For a certain amount of entrained water needed for internal curing, an accurate assessment of the absorption capacity of SAP in cement paste is necessary rather than other solutions to properly proportion the dosage of SAP in cement-based materials, thus attaining their effectiveness in mitigating autogenous shrinkage with fewer adverse effects. In this paper, early-age performances of cement paste with and without SAP, including rate of heat evolution, capillary pressure and rheological properties, are compared, with simultaneous observation of the particle size of SAP in the cement paste. Results indicate that the absorption capacity of SAP in situ can be quantitatively evaluated through the comparison of the rate of heat evolution and capillary pressure from the addition of water to setting. The ideal dosage can be confirmed based on the theoretical amount of entrained water needed for internal curing.
Scale effect in centrifuge tests of helical anchors in sand
Authors: Schiavon José Antonio , Tsuha Cristina de Hollanda Cavalcanti , Thorel Luc
Published: May 2016

Centrifuge modelling is an advantageous technique to simulate the behaviour of helical anchors in sand. The uplift capacity of a single-helix anchor is the sum of the helix bearing resistance plus the shaft resistance; therefore, recommendations to avoid the grain-size effect of previous model tests on plate anchors and on regular piles appear to be reasonable for helical anchor model tests. However, there are two important differences between centrifuge models of plate anchors and helical anchors: the ratio of the helical plate to the shaft diameter and the plate installation procedure. Consequently, the shaft friction and the plate bearing resistance of helical anchors can be affected by the scaling effect in a different manner. To clarify this uncertainty, this study was proposed to investigate the grain-size effect on the results of uplift capacity of helical anchor models in sand. Anchor models with different scales were tested to simulate the same prototype in very dense dry sand in a centrifuge. These experiments have shown that no scale effect was found for models with the ratio of the effective helical radius to the average grain size >58. The findings obtained here could guide future centrifuge model studies on helical anchors.

Her cardiac enzymes were elevated. A bedside echocardiogram showed revealed, hypercontactile basal segments and apical dyskinesis, a global ejection fraction of 40%. She underwent emergency coronary angiogram (CAG) which revealed normal epicardial coronaries. Left ventriculography revealed systolic apical ballooning and hypercontractile basal segments with impaired LV systolic function (LVSF). With aggressive medical therapy, the patient's symptoms improved. Left ventriculography after 10 days showed normalization of the systolic apical ballooning and the LVSF. When questioned, subsequently, the patient revealed that she had recently experienced severe emotional stress due to financial instability.
Takotsubo Syndrome Therapy: Current Status and Future Directions
Authors: Singh Kuljit , Akashi Yoshihiro J , Horowitz John
Published: May 2016

Tako-Tsubo Cardiomyopathy (TTC), which is now known as Tako-Tsubo Syndrome (TTS) is a transient left ventricular (LV) systolic dysfunction of uncertain pathogenesis, which occurs predominantly in ageing women. There is considerable uncertainty regarding the management of TTS related acute and chronic issues and most of the evidence regarding therapy comes from retrospective data and case studies. In this review we have tried to concise the available information on the TTS therapeutics to help clinicians make treatment decisions in patients diagnosed with TTS. At the same time we have highlighted some of the uncertainties regarding TTS therapy, in particular the inability of b-blocker therapy to improve survival or prevent recurrence. We have also emphasized the issue of incomplete recovery in some cases of TTS where there is ongoing inflammation and evidence of impaired myocardial energetics despite normalization of LV ejection fraction. Although there is no scientific evidence on how to improve or fasten the recovery of TTS, we believe therapy improving energy efficiency may play some role in future. Lastly, we would like to reiterate that in the absence of randomized studies evaluating medical therapy in TTS, the treatment for this syndrome remains entirely empirical and should be individualized according to the patient characteristics at the time of presentation.
Recurrence of Takotsubo Cardiomyopathy
Authors: Kato Ken , Kitahara Hideki , Kobayashi Yoshio
Published: May 2016

Takotsubo cardiomyopathy (TC) is transient systolic dysfunction of the left ventricle (LV) occurring mainly in post-menopausal women after a stressful event. It is associated with characteristic LV contraction patterns. While the prognosis for TC patients is generally favorable, some patients experience recurrence of TC, once or sometimes multiple times. This review summarizes current knowledge of recurrence of TC. Recurrence rate of TC has ranged from 0 to 10%. Although clinical correlates determining recurrence of TC have not been identified, the recurrence rate is higher in patients with severe LV dysfunction during initial TC event or younger female patients. Preventive therapy of recurrent TC has not been established. β-blockers are commonly used in the prevention of TC recurrence but no evidence to date supports their efficacy. Angiotensin converting enzyme inhibitors and angiotensin receptor blockers may have a role to prevent recurrence of TC. In patients with multiple recurrent TC triggered by emotional stress or suffering from anxiety disorder, psychological counseling or antianxiety drugs may be beneficial for preventing recurrence of TC.
Takotsubo Syndrome: A Complex and Varied Clinical Syndrome
Authors: Shewan Louise , Henein Michael , Coats Andrew
Published: May 2016

This special issue includes expert reviews and original research on Takotsubo syndrome (TTS) including the history of its identification and the unravelling of the pathophysiology of the different variants of the syndrome. The role of neurological stress or catecholaminergic overload are reviewed, as is the role of CNS disorders triggering TTS. Clinical presentation patterns of TTS and the most useful diagnostic tests are reviewed, including original research into a novel clinical score the ‘GET QT' score to help in rapid differentiation of TTS from STEMI. There is also a review of TTS in the intensive care unit setting.  The mechanisms of TTS including the role and assessment of the microcirculation in generating the classical myocardial dysfunction are reviewed in detail, as are the pathophysiological pathways of recurrent TTS. Lastly Singh, Akashi and Horowitz review the emerging treatment options for TTS. They issue also includes multiple elegant and fascinating case reports. TTS has come of age and now urgently adequate sized RCT’s.

O Currículo das Licenciaturas em Música: comreendendo o habitus conservatorial como ideologia incorporada
Authors: Pereira Marcus Vinicius
Published: May 2016

Resumo O texto apresenta análises parciais de projetos políticos pedagógicos de cursos de licen- ciatura em música brasileiros ancoradas na teoria crítica do currículo e na sociologia da cultura, especialmente nas proposições de Michael Apple e Pierre Bourdieu. As análises evidenciam uma ideologia musical incorporada na forma de um habitus, aqui chamado de habitus conservatorial que tem a música erudita como conhecimento oficial e como capital legitimado em disputa no campo em questão, determinando o sistema de cotação do que conta como conhecimento musical valorizado. Abstract This text presents partial analysis of some curricular documents of Brazilian music teacher education programs. This analysis is based in the curriculum critical theories and in the sociology of culture, especially in the propositions of Michael Apple and Pierre Bourdieu. The results show a musical ideology incorporated as habitus, which is called here conservatorial habitus that has the classical music as the official knowledge and as a legitimized capital in dispute in the field, classical music that also determines the quotation system of what counts as a valued musical knowledge.

Authors: Baptista Maria , Lamego Vanessa
Published: May 2016

Resumo O presente artigo procura compreender e aprofundar a relação existente entre a festa e o teatro e evidenciar de que modo essa associação pode ser integrada na atividade turística, nomeadamente através do conceito de Turismo de Teatro. Este estudo produz, assim, um levantamento bibliográfico e uma discussão teórica acerca desta temática, onde se concluiu que apesar de não ser evidente a relação entre a festa e o teatro, esta revela-se muito claramente através do ritual e do jogo, dois elementos presentes em ambas as práticas. Com efeito, o sector do turismo não se restringe apenas aos meios de alojamento, transporte e entretenimento, mas também a todas as manifestações culturais que motivam a visita dos turistas. Nestas manifestações podem incluir-se o teatro e a festa, dois elementos que não foram desenhados com o objetivo turístico, mas que possuem grande potencialidade a este nível e que configuram um tipo de turismo cultural que tem vindo a ser designado na literatura da especialidade por Turismo de Teatro. Abstract This article seeks to understand the relationship between the festival and the theatre and show how this relationship can be integrated in tourist activity, namely through the concept of Theatre Tourism. This study results, thus, in a literature review and a theoretical discussion about these issues, in which was concluded that although the relationship between the festival and the theatre it’s not obvious, it is clearly revealed through the ritual and the game, two elements present in both practices. Indeed, the tourism sector is not restricted only to the accommodation, transportation and entertainment segments, but also to the cultural events that motivate tourist’s visits. These manifestations may include the theatre and the festival, two elements that were not designed with a tourist purpose, but have a great potential at this level and form a type of cultural tourism that has been designated in the literature as Theatre Tourism.

Authors: Alvarado Ramírez Karla María , Pumisacho Álvaro Víctor Hipólito
Published: May 2016

El propósito de esta investigación es examinar de manera empírica y cuantitativa el grado de relación existente entre la cultura organizacional y la innovación organizacional. Se realizó un estudio con 260 personas que ocupan cargos operativosy administrativos en las pymes del Distrito Metropolitano de Quito. Se analizó el tipo de cultura organizacional a través de la metodología propuesta por Cameron y Quinn, basada en el modelo Competing Value Framework, que permite identificar y clasificar a las empresas por el tipo de cultura dominante que presentan. Los resultados muestran que los tipos de cultura que inciden de forma favorable en la innovación organizacional son la cultura clan, de mercado y la de tipo adhocrática; sin embargo, una cultura muy jerarquizada presenta una correlación baja. Estos resultados resaltan la importancia que tiene la cultura organizacional, y refuerzan la idea de que el liderazgo genera mejoras en el desempeño e innovación organizacional.
Una aproximación a la relación entre el desarrollo regional y el emprendimiento en Colombia
Authors: Duran Peralta Julian
Published: May 2016

En el presente trabajo se realiza una aproximación a la relación endógena entre el desarrollo económico de los municipios en Colombia y su tasa de emprendimiento. Por lo tanto, se explora un modelo de dos ecuaciones simultáneas donde las variables endógenas son el PIB del municipio como indicador de su nivel de desarrollo y la tasa de empleadores más cuenta propia con alto grado educativo como variable que representa el emprendimiento, y se utiliza la información del Censo de Población 2005. La estimación obtenida muestra que existe una relación positiva y de doble vía entre el PIB municipal y la tasa de emprendimiento local.
