Shared and unique risk factors for depression and diabetes mellitus in a longitudinal study, implications for prevention: an analysis of a longitudinal population sample aged ⩾45 years
Authors: Chireh Batholomew , D’Arcy Carl
Published: July 2019

Objective:

The objective of this study was to examine shared and unique risk factors for incident depression and diabetes mellitus in a national longitudinal population-based survey.

Methods:

Canadian National Population Health Survey (NPHS) longitudinal study was used. A subsample of the initial NPHS sample ( n = 4845), free of depression or diabetes mellitus at baseline was tracked over a 10-year period. Univariate and multivariate modified Poisson regression models were used to estimate the relative risk (RR). Stratified analyses by sex were conducted to measure its moderating role. The goodness-of-fit of the various models was tested.

Results:

The cumulative incidence rate of major depressive disorder and incident diabetes mellitus at 10-year follow-up were 4.1% and 10.1% respectively. Hypertension, daily smoking, physical inactivity and being overweight or obese were shared risk factors for major depressive episode and diabetes mellitus. Being female, family stress, traumatic events, having any chronic disease or heart disease were uniquely associated with depression while increasing age and ethnicity (non-white) were unique risk factors for diabetes mellitus. Also, underweight, family stress, chronic disease, and heart disease were risk factors for major depressive disorder in both sexes. Six risk factors, age, ethnicity (non-white), high blood pressure, daily smoking, physical inactivity, and body mass index were associated with incident diabetes mellitus in both sexes.

Conclusion:

We found common risk behaviors/conditions not specific to either diabetes mellitus or depression. These risks have also been implicated in the development of a variety of chronic diseases. These findings underline the importance of public health prevention programs targeting generic risk behaviors.
Reflecting on the contemporary relevance of the forgotten management pioneers: A creative auto/biography
Authors: Nienaber Hester
Published: July 2019

Management theory and practice are characterised by the ‘theory–practice gap’. A way of addressing this divide is to engage in reflective practice, in this instance, a creative auto/biography. This different way of presenting an old issue demonstrates how the original teachings of the management pioneers remain relevant today. The central issues are the purpose of the organisation and the role of both leadership and employees in unlocking human competence in pursuit of organisational performance. The concepts ‘autonomy’ and ‘control’ transpired as crucial, which could easily be misunderstood or misapplied. This personal reflection presents evidence on which to base change, enhancing the well-being of employees, societies and the profit of organisations. This article contributes to knowledge by making inaccessible knowledge, accessible and inclusive, and the expectation that the meaning emanating from this reflection will result in the management audience to reconsider management, advancing management science and benefitting society at large.

Authors: Cinque Mark E. , DePhillipo Nicholas N. , Moatshe Gilbert , Chahla Jorge , Kennedy Mitchell I. , Dornan Grant J. , LaPrade Robert F.
Published: July 2019

Background:

There is significant discrepancy in the reported vascularity within the meniscus, and a progressively diminishing blood supply may indicate a differential healing capacity of tears that is dependent on the affected meniscal zone.

Purpose:

To examine the outcomes after inside-out meniscal repair in all 3 meniscal vascularity zones.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Patients were included if they underwent inside-out meniscal repair by a single surgeon between 2010 and 2014 and had a minimum 2-year follow-up. Patients were divided into 3 groups based on the meniscal tear location (red-red, red-white, and white-white zones) as determined during an intraoperative assessment. Patient-reported outcome scores were obtained at final follow-up.

Results:

A total of 173 patients (mean age, 33.6 ± 14.3 years) were included, with a mean follow-up of 2.9 ± 0.9 years. All patients demonstrated significant improvements with inside-out meniscal repair from preoperatively to postoperatively, regardless of the meniscal tear location. Patients who underwent meniscal repair in the red-red and red-white zones had significantly increased postoperative Tegner, Lysholm, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores compared with patients who underwent meniscal repair in the white-white zone ( P < .05). Patients who underwent acute repair (≤6 weeks) demonstrated significantly higher improvements on the Tegner activity scale (acute: 5.8 ± 2.2; chronic: 4.6 ± 2.2; P = .001) and Lysholm score (acute: 85.6 ± 13.3; chronic: 80.8 ± 13.5; P = .025) compared with patients treated beyond 6 weeks from injury, regardless of the meniscal tear zone. Patients with grade IV femoral condyle chondral lesions at the time of surgery had significantly inferior outcomes compared with patients with grade I through III chondral lesions, regardless of the meniscal tear zone. Three patients (1.7%) subsequently underwent revision inside-out repair, and 3 (1.7%) underwent partial meniscectomy.

Conclusion:

Patients who underwent inside-out meniscal repair demonstrated significant improvements on subjective outcome measures at a minimum 2-year follow-up, regardless of the meniscal tear zone. Inside-out meniscal repair is recommended for potentially reparable meniscal tears in all 3 vascular zones; however, improved outcomes can be achieved when performed acutely, in the absence of full-thickness femoral condyle chondral injuries, and in the red-red and red-white zones.

Published: July 2019

Objective

A number of in vitro and clinical studies have suggested potential antineoplastic effects of metformin. The impact of this medication on outcomes in head and neck cancer is less clear. Our aim was to determine the effect of metformin on outcomes within our large cohort of head and neck cancer patients with Type II Diabetes (T2DM).

Study design

Retrospective cohort study.

Setting

Tertiary Cancer Centre.

Subjects and methods

A retrospective review of individuals with head and neck squamous carcinoma (HNSCC) and T2DM between January 2005 and December 2011 at Princess Margaret Cancer Centre was conducted. Medication history was obtained from surveys at initial presentation and electronic medical record review. Using Cox regression analyses, the association between metformin use and local, regional and distant failures was explored. Subgroup analyses were conducted for oral cavity, oropharynx and larynx.

Results

A total of 329 HNSCC patients with T2DM were identified, including 195 metformin users and 134 non-metformin users. Patients were well-matched in terms of clinical, pathologic, and treatment factors. No difference in local, regional, or distant failure was observed between diabetic metformin users and diabetic non-metformin users for the entire cohort or within subgroup analysis for subsite. No difference between the two groups was observed for overall survival, recurrence-free survival, and disease-specific survival at 5 years.

Conclusion

No association between metformin use and oncologic outcomes were observed in this large cohort of HNSCC patients. Multicenter, prospective studies may be needed to verify previous studies identifying a potential anti-neoplastic effect of this medication.
Intestinal barrier dysfunction in severe burn injury
Authors: He Wen , Wang Yu , Wang Pei , Wang Fengjun
Published: July 2019

Severe burn injury is often accompanied by intestinal barrier dysfunction, which is closely associated with post-burn shock, bacterial translocation, systemic inflammatory response syndrome, hypercatabolism, sepsis, multiple organ dysfunction syndrome, and other complications. The intestinal epithelium forms a physical barrier that separates the intestinal lumen from the internal milieu, in which the tight junction plays a principal role. It has been well documented that after severe burn injury, many factors such as stress, ischemia/hypoxia, proinflammatory cytokines, and endotoxins can induce intestinal barrier dysfunction via multiple signaling pathways. Recent advances have provided new insights into the mechanisms and the therapeutic strategies of intestinal epithelial barrier dysfunction associated with severe burn injury. In this review, we will describe the current knowledge of the mechanisms involved in intestinal barrier dysfunction in response to severe burn injury and the emerging therapies for treating intestinal barrier dysfunction following severe burn injury.

Published: July 2019

PURPOSE

We investigated the impact of screening rural patients on referral and management of cervical cancer in Tanzania.

METHODS

After reviewing more than 10,000 medical records of patients with cervical cancer who visited Ocean Road Cancer Institute (ORCI) from 2005 to 2014, 108 patients were from the rural communities of Bagamoyo and Chalinze. We abstracted demographic, clinical, and lifestyle factors and linked the data set to databases of all 1,151 patients who visited the Bagamoyo screening clinic from 2011 to 2014 and 1,273 patients who visited the Chalinze screening clinic from 2012 to 2014.

RESULTS

After initiation of the rural screening clinics, difference in duration from diagnosis to prescribed treatment increased from 50.5 to 88 days ( P = .030), and duration from referral to treatment increased from 38.6 to 101.3 days ( P = .041). Proportion of patients who received combination chemoradiotherapy increased from 34.3% to 69% ( P = .001) and completion of treatment decreased from 94.4% to 72.41% ( P = .002) after initiation of the ORCI screening clinic. Patients who visited Muhimbili National Hospital had significantly shorter periods between referral and prescribed treatment than patients who did not use the Muhimbili National Hospital (mean ± standard deviation, 49.4 ± 128.8 and 112.1 ± 195.31 days, respectively; P = .010). Patients who were treated at ORCI had significantly shorter periods between diagnosis and referral to treatment (mean ± standard deviation, 31.4 ± 62.35 and 36.4 ± 121.79 days, respectively; P = .005).

CONCLUSION

Future research should focus on investigating barriers to seeking cancer care, benefits of chemoradiotherapy in this population considering the change in prescribed treatment, and time until diagnosis and treatment. Prescription of complex treatments that require more visits to treatment centers may also contribute to decline in completion of treatment.
Rapid cold hardening protects against sublethal freezing injury in an Antarctic insect

Published: July 2019

Rapid cold hardening (RCH) is a type of beneficial phenotypic plasticity that occurs on extremely short time scales (minutes to hours) to enhance insects’ ability to cope with cold snaps and diurnal temperature fluctuations. RCH has a well-established role in extending lower lethal limits, but its ability to prevent sublethal cold injury has received less attention. The Antarctic midge, Belgica antarctica is Antarctica's only endemic insect and has a well-studied RCH response that extends freeze tolerance in laboratory conditions. However, the discriminating temperatures used in previous studies of RCH are far below those ever experienced in the field. Here, we tested the hypothesis that RCH protects against nonlethal freezing injury. Larvae of B. antarctica were exposed to either control (2°C), direct freezing (-9°C for 24 h), or RCH (-5°C for 2 h followed by -9°C for 24 h). All larvae survived both freezing treatments, but RCH larvae recovered more quickly from freezing stress and had significantly higher metabolic rates during recovery. RCH larvae also sustained less damage to fat body and midgut tissue and had lower expression of two heat shock protein transcripts (hsp60 and hsp90), which is consistent with RCH protecting against protein denaturation. The protection afforded by RCH resulted in energy savings; directly frozen larvae experienced a significant depletion in glycogen energy stores that was not observed in RCH larvae. Together, these results provide strong evidence that RCH protects against a variety of sublethal freezing injuries and allows insects to rapidly fine-tune their performance in thermally variable environments.
The experience of financial burden for patients with multimorbidity: A protocol for a systematic review of qualitative research
Authors: Larkin James , Foley Louise , Smith Susan M. , Harrington Patricia , Clyne Barbara
Published: July 2019

Introduction: Multimorbidity is increasingly important due to its high disease burden, prevalence and related high healthcare utilisation. For patients, there is also a high financial burden due to direct and indirect costs arising from their multimorbidity. It is unclear how this financial burden affects patients. This study aims to synthesise qualitative evidence exploring the experience of financial burden from the perspective of patients with multimorbidity.

Methods: The review will be reported using the ENTREQ guidelines. A systematic search of Lilacs, PubMed, CINAHL, EMBASE, PsycINFO, and Applied Social Sciences Index and Abstracts will be conducted using a predefined search strategy. A search of fourteen pre-specified websites will be conducted for grey literature. Forward and backward citation checking of included studies will be conducted also. Studies will be included if they contain primary qualitative research and reference the experience of financial burden from the perspective of adult (≥ 18 years) community dwelling patients with multimorbidity. Studies from any country and in any language will be included. Titles and abstracts of search results will be screened; if a study appears relevant, then full-texts will be screened for eligibility. Study characteristics of included articles will be extracted. Study quality will be evaluated using the critical appraisal skills programme (CASP) checklist for qualitative research. These three processes will be carried out by two reviewers independently. Thematic-synthesis will be used to analyse data. This will be carried out by one reviewer and cross-checked by a second reviewer. The GRADE CERQual approach will be used to assess the overall confidence in the evidence.

Discussion: This review will identify evidence on the experiences of financial burden for patients with multimorbidity and forms part of a project to support consideration of financial burden for patients in the development of clinical guidelines in Ireland.

Published: July 2019

Background and Aim: A previous study divided Indonesian bovine viral diarrhea virus (BVDV)-1 into subgenotypes BVDV-1a to BVDV-1d based on the partial NS5B gene using strain Bega as reference for BVDV-1a. In fact, it is clustered into BVDV-1c with strain Bega-like Australia. BVDV genotyping has been done on isolates from Jakarta, West and Central Java, but East Java isolates have not been genotyped. This study aimed to analyze genetic variability and amino acid residues in the nucleotide-binding pocket of the NS5B gene from infected cattle. Materials and Methods: Samples were obtained from the Sera Bank originating from active and passive surveillance of cattle that had been tested for BVDV antigen from 2013 to 2017. Detection of the p80 antibody and BVDV genotyping was carried out using ELISA and nested-multiplex-polymerase chain reaction (PCR), respectively. We defined 15 nested PCR products for partial sequencing of NS5B. Those field samples were selected from each location and year using proportional calculation as a representative sample. Homological and phylogenetic analyses of the partial NS5B gene were performed using BLAST and MEGA version 6. Results: Based on the phylogenetic tree analysis using 360 nucleotides as the partial NS5B gene, Indonesian BVDV-1 isolates from Central and East Java were subdivided to BVDV-1a (n=9), BVDV-1b (n=1), and BVDV-1c (n=5). In the present study, the homology of BVDV subgenotype -1a, -1b, and -1c was compared to the BVDV GenBank data and found 90-93%, 93%, and 92-95% respectively with the average pairwise distance of 0.207. A point mutation was shown at R283K of all BVDV isolates based on the sequence of three amino acid residues R283, R285, and I287 in the nucleotide-binding pocket as a part of the encoded RNA-dependent RNA polymerase. Conclusion: This study revealed the genetic variability of BVDV infecting cattle in Central Java and East Java, Indonesia, the subtypes BVDV-1a, BVDV-1b, BVDV-1c, and a point mutation at the R283K residue.
Active Fault Zones of The 2006 Yogyakarta Earthquake Inferred from Tilt Derivative Analysis of Gravity Anomalies
Authors: Handayani Lina
Published: July 2019

The 2006 Yogyakarta Earthquake had caused a disaster in Bantul area. Several institutions had reported different results for the epicenter location. However, aftershocks studies indicated that the rupture area was at about 10 km east of Opak Fault. Analysis of gravity anomaly, including several degrees of residual anomalies and tilt derivative, facilitated this regional tectonic study to determine the structural constraints on the main earthquake and its aftershocks. The Yogyakarta area was primarily characterized by several SW-NE faults; one of them is the Opak Fault. Among those faults,, there are a series of WNW-ESE faults. Several groups of these lineations indicated a presence of some pairs of parallel strike-slips faults that formed pull-a-part basins. The obtained structural pattern has signified the dynamic response of the force from the subduction of the Australian Plate toward Sunda (Eurasia) Plate.  The subduction force produced the strike-slip fault in a parallel direction of subduction, and subsequently, the faults caused the formation of thrust structures that are perpendicular to them.Gempabumi Yogyakarta pada tahun 2006 telah menyebabkan bencana di daerah Bantul dan sekitarnya. Lokasi episenter yang ditentukan oleh beberapa lembaga menunjukkan hasil yang berbeda. Tetapi analisa gempabumi susulan telah menunjukkan daerah pegerakan hingga 10 km ke sebelah timur dari Sesar Opak. Analisa anomali gayaberat yang terdiri dari perhitungan anomali sisa dan turunan kemiringan (tilt derivative) diharapkan dapat membantu studi tektonik regional dalam menentukan batasan struktur yang menyebabkan kejadian gempabumi di daerah Yogyakarta. Daerah ini dicirikan oleh sesar-sesar berarah BD (Barat daya)-TL (Timur laut), yang salah satunya adalah Sesar Opak. Di antara sesar-sesar tersebut, terdapat pula deretan sesar-sesar berarah BBL (Barat barat laut)-TTG (Timur tenggara). Beberapa kelompok kelurusan-kelurusan membentuk kemungkinan adanya cekungan pull-a-part, yang terbentuk karena adanya deretan sesar-sesar strike-slip. Pola struktur yang diperoleh menunjukkan respon dinamik dari subduksi Lempeng Australia terhadap Lempeng Eurasia (Sunda). Tekanan dari gaya subduksi menyebabkan terbentuknya sesar-sesar strike-slip. Kemudian sesar-sesar tersebut menyebabkan adanya struktur sesar naik yang tegak lurus terhadapnya.

Authors: Sari Anggun Mayang , Soebowo Eko , Fakhrurrozi Afnindar , Syahbana Arifan Jaya , Tohari Adrin
Published: July 2019

Bandung Basin consists of Sunda-Tangkuban Perahu volcanic deposit that is made of lake sediment and an alluvial fan with fine to coarse-grained materials such as clay, silt and sand. The area is surrounded by several earthquake sources such as the Lembang, Cimandiri, and Baribis Faults. Therefore, it is important to understand soil dynamic problems with respect to seismic sources and soil properties. This research aims to investigate velocity amplification of the Bandung Basin using microtremor measurements and site classification based on the Standard Penetration Test (SPT) and Cone Penetrometer Test (CPTu). Velocity amplification was analyzed using the horizonal to vertical H/V spectral ratio, and site classification was determined using and  values. Microzonation maps were developed using Geographical Information System (GIS) to determine the correlation between soil velocity amplification and site class. The results revealed that velocity amplification levels in the Bandung Basin vary with a range of 1.3 to 26.5. Site classification ranges from very dense soil and hard rock (class C), stiff soil (class D) to soft clay soil (class E). Site class E dominates the southeast part of the Bandung Basin with a high value of soil amplification. This scientific information is critical for further spatial planning focusing on infrastructure and residential building. Cekungan Bandung berasal dari endapan vulkanik Sunda-Tangkuban Perahu yang terdiri dari sedimen danau dan kipas aluvial dengan material berbutir halus hingga kasar seperti lempung, lanau, dan pasir. Daerah ini juga dikelilingi oleh beberapa sumber gempa yakni sesar Lembang, Cimandiri, dan Baribis. Oleh karena itu masalah dinamika tanah yang dipengaruhi oleh sumber seismik dan sifat tanah perlu menjadi perhatian. Tujuan penelitian ini adalah untuk mengetahui amplifikasi kecepatan tanah di wilayah cekungan Bandung dengan menggunakan alat mikrotremor dan metode site classification berdasarkan uji SPT dan CPTu. Amplifikasi kecepatan dianalisis menggunakan perbandingan rasio spektral H/V dan site classification yang diperoleh dengan menggunakan nilai  dan . Peta mikrozonasi disusun menggunakan teknik Sistem Informasi Geografis (SIG) untuk menentukan korelasi amplifikasi tanah dan site class tanah. Hasil penelitian menunjukkan bahwa tingkat amplifikasi kecepatan di Cekungan Bandung bervariasi, berkisar 1,3 hingga 26,5. Site classification berkisar dari tanah yang sangat padat dan batuan keras (kelas C), tanah kaku (kelas D) hingga tanah lempung lunak (kelas E). Hasil penelitian menunjukkan site class E mendominasi bagian selatan Cekungan Bandung dengan nilai amplifikasi tanah yang tinggi. Informasi ilmiah ini diperlukan untuk perencanaan tata ruang kedepannya, dengan fokus pada infrastruktur dan bangunan tempat tinggal.
ДАРКНЕТ КАК УСКОЛЬЗАЮЩАЯ СФЕРА ПРАВОВОГО РЕГУЛИРОВАНИЯ
Authors: Васильев Антон , Ибрагимов Жамалaден , Васильева Ольга
Published: July 2019

Правовая система России в последние десятилетия очевидно столкнулась с вызовами глобальной электронной сети. Связаны они прежде всего с тем, что многие группы правоотношений, традиционно существовавшие в «материальном» виде, перемещаются в киберпространство. Речь идет не только о масштабной цифровизации сферы купли-продажи, но и о тех областях права, в отношении которых их перемещение в интернет ранее никто не предполагал (сфера государственных услуг, электронное избирательное право и пр.). Еще более угрожающей представляется проблема использования Даркнет в криминальных сферах.

Отсутствие какого бы то ни было системного правового регулирования в этой области и даже минимального набора основных правовых терминов делает отечественное законодательство беззащитным перед стремительно развивающимся Даркнентом. В статье предлагается авторское осмысление основных проблемных вопросов Даркнета как предмета правового регулирования, соотношение идей свободы и анонимности в сети и защиты государственных и частных интересов. Формулирование концепции правового регулирования в отношении Даркнета должно послужить отправной точкой на этом пути.

Published: July 2019

Hamamelidaceae s.l. – семейство, которое служит своеобразным мостом между базальными евдикотами и розидами, поэтому лучшее понимание филогении семейства важно для выявления эволюционных закономерностей в диверсификации евдикот. Межродовые отношения у Hamamelidaceae s.l. являются предметом дискуссий. В ходе работы были реконструированы филогенетические взаимоотношения между 37 видами Hamamelidaceae s.l. и Cercidiphyllum japonicum в качестве внешней группы. Для этого молекулярно-генетические данные (3маркера: matK, trnL-trnF, ITS-5.8S rRNA) были обработаны методом максимального правдоподобия. Полученнаякладограмма показывает, что сем. Hamamelidaceae s.l. полифилетично. Hamamelidaceae s.s. образует монофилетическую группу. На кладограмме выделено пять основных клад: Altingiaceae; Rhodoleioideae sensu Endress вместес Exbucklandioideae sensu Endress (исключая Disanthus и Mytilaria); Mytilaria; Disanthus; Hamamelidoideae sensuEndress. С небольшими изменениями в Hamamelidoideae поддерживается монофилия нескольких ранее признанных групп, в том числе триб: Corylopsideae sensu Endress, Eustigmateae sensu Endress (включая Molinadendron),Fothergilleae (включая Hamamelis, исключая Molinadendron и Matudaea), а также подтриб Dicoryphinae sensu Endress и Loropetalinae sensu Endress (включая Matudaea).

Формирование флористических лесных комплексов юга Сибири
Authors: Харитонцев Б. С.
Published: July 2019

Леса Сибири разнообразны по фитоценотическим признакам и генезисным особенностям. Для каждого типа леса характерны свои доминанты с набором верных видов. Подобные сочетания формировались в течение длительных временных отрезков в лесные комплексы. На юге Сибири от Зауралья до Байкала можно выделить комплексы остепненных сосняков, западносибирских березняков и липняков, южносибирских реликтовыхлипняков, кедрово-пихтовых и лиственично-сосновых лесов. Присутствие в них эндемиков (реже реликтов) игрупп верных видов подчеркивает оригинальность каждого из комплексов. Экологическая специфичность комплексов обуславливает отбор видов, как автохтонных, так и мигрантов при формировании комплекса.

Authors: Холбоева С. А.
Published: July 2019

В работе рассматриваются некоторые особенности флористического и фитоценотического разнообразия сообществ Ulmus pumila L. в пределах Западного Забайкалья. Наибольшие площади занимают коренныесклоновые ильмовники, а также сообщества ильмовников на разновозрастных залежах. Проведен сравнительныйанализ систематической, экологической, биоморфологической структуры ценофлор залежных и коренных сообществ ильмовников. Спектр преобладающих семейств и родов в ценофлорах показывает их высокое сходство.Спектр экологического и биоморфологичесого состава ценофлор подтверждает ее степной характер и высокийуровень адаптации U. pumila к аридным условиям степей региона. Анализ фитоценотического разнообразия позволяет предположить, что восстановительная сукцессия с участием ильма на залежных участках, расположенных в основном на выровненных и пологосклоновых поверхностях днищ котловин, приводит к формированиюильмовников с преобладанием рыхлодерновинных злаков в травянистом ярусе.

THE FATIGUE BEHAVIOUR OF GFRP BARS - EXPERIMENTAL STUDY
Authors: Januš Ondřej , Girgle František , Rozsypalová Iva , Kostiha Vojtěch , Bodnárová Lenka , Štěpánek Petr , Prokeš Jan
Published: July 2019

The paper describes an experimental program for studying the fatigue performance of GFRP bars, which has been initiated by the authors. Two different test configurations were used to assess the fatigue behaviour. The bare specimens were tested within the first series. A modified gripping system was used to reduce eccentricity when the bar was not directly fixed. However, the boundary conditions seem to affect the results. The second series consisted of a set of specimens of bars embedded in concrete. This configuration seems appropriate for determination of fatigue life of GFRP bars. Two S-N curves for bare bars and bars embedded in concrete were created and compared. Significant reduction of interlaminar shear strength at the beginning of fatigue loading proved matrix or fibre/matrix interface damage.

Authors: Prošek Zdeněk , Tesárek Pavel , Trejbal Jan , Horová Tereza
Published: July 2019

This paper deals with the use of high-speed milling process for recycling old concrete and direct determination of the potential of input waste. For this purpose, three different types of waste concrete were used: prefabricated railway sleeper, structural concrete of monolithic pillar and prefabricated drainage gutter. The paper directly examines the chemical and phase composition by XRF, X-Ray Diffraction (XRD), Energy Dispersive X-ray Spectrometry (EDS) and microscopic analysis, particle size distribution and pH of the recycled material. Results of those analysis are used to select suitable recycled material. The suitability of choice is supported by mechanical tests of 28-day old cement pastes, where the compressive strength and dynamic modulus of elasticity are observed properties. Specimens measuring 40 × 40 × 160mm are composed of 70 wt.% Portland cement and rest is micronized concrete. In all cases, the results are compared with the reference material.

Published: July 2019

Em um cenário onde os proprietários do capital estão distantes da gestão das empresas, cresce a busca por melhores práticas de controle gerencial que induzam os executivos a depreenderem mais esforços para alcançar resultados cada vez maiores. Em consonância à Teoria da Agência o presente estudo tem por objetivo verificar a relação entre avaliação de desempenho e remuneração de executivos com o desempenho econômico-financeiro das empresas brasileiras. A amostra não probabilística é formada por 71 empresas de capital aberto com demonstrativos divulgados pela Comissão de Valores Mobiliários (CVM) no período de 2010 a 2016. Com base nos resultados da análise de regressão linear múltipla infere-se a existência de relação entre o uso de indicadores de desempenho, a remuneração recebida pelos diretores estatutários e o desempenho operacional das empresas brasileiras. Principalmente no que se refere aos indicadores não financeiros e remuneração total e variável que se mostrou significativa em relação a margem operacional da empresa. Como implicações práticas, o estudo demonstrou que as empresas brasileiras de capital aberto tendem a utilizar indicadores de avaliação de desempenho dos executivos e também a remuneração total e variável para alinhamento de objetivos operacionais e desempenho não financeiros, objetivando a perpetuidade do negócio no mercado ou inclusive outros fatores como melhor nível de governança corporativa.

The perennial selenium (Se) hyperaccumulator Cardamine hupingshanensis (Brassicaceae) thrives in aquatic and subaquatic Se-rich environments along the Wuling Mountains, China. Using bright-field and epifluorescence microscopy, the present study determined the anatomical structures and histochemical features that allow this species to survive in Se-rich aquatic environments. The roots of C. hupingshanensis have an endodermis with Casparian walls, suberin lamellae, and lignified secondary cell walls; the cortex and hypodermal walls have phi (Φ) thickenings; and the mature taproots have a secondary structure with a periderm. The stems possess a lignified sclerenchymal ring and an endodermis, and the pith and cortex walls have polysaccharide-rich collenchyma. Air spaces are present in the intercellular spaces and aerenchyma in the cortex and pith of the roots and shoots. The dense fine roots with lignified Φ thickenings and polysaccharide-rich collenchyma in the shoots may allow C. hupingshanensis to hyperaccumulate Se. Overall, our study elucidated the anatomical features that permit C. hupingshanensis to thrive in Se-rich aquatic environments.
