“And this is the view from outside my window”: On text and image interplay in university website blogs
Authors: Tomášková Renáta 
Published: January 2018

Abstract
The paper focuses on the institutional website as a complex genre with a relatively discontinuous inner structure, which is, however, coherent and cohesive, and unified by a common communication goal(s). The website is viewed as a discourse colony consisting of independent but related components realized in an array of subgenres, some of which are typical of the academic/institutional environment while others come from different discourse domains and are employed as embedded genres. The paper focuses on the blog as an embedded genre, its forms and functions within university websites, and particularly on its potentially multimodal character, i.e. the interplay of the verbal content of the blog and the non-verbal elements, esp. photographs, which co-create the producer’s message to the addressee. Drawing upon the recently developed field of multimodal discourse analysis within Hallidayan Systemic Functional Linguistics, particularly Martinec and Salway’s model, the paper explores the level to which the modes are integrated and the ways they contribute to meaningmaking in the genre.
Aminkomplexe des Goldes, Teil 9: Gold(I)-halogenid-Komplexe mit primären und azyklischen sekundären Aminen und ihre Oxidation zu Gold(III)-Derivaten
Authors: Döring Cindy , Jones Peter G. 
Published: January 2018

Abstract
The reaction of (tht)AuX (X=Cl or Br; tht=tetrahydrothiophene) with various primary amines L leads to products of the form [L2Au]+X−. Packing diagrams of the corresponding structures are dominated by N–H···X hydrogen bonds and (in some cases) aurophilic contacts. The cyclohexylamine derivative was already known as its dichloromethane ⅔-solvate; we have isolated the solvent-free compound and its pentane ¼-solvate, which all show different packing patterns. With acyclic secondary amines, the products are more varied; LAuX and [L2Au]+[AuX2]− were also found. These gold(I) products were generally formed in satisfactory quantities. The attempted oxidation to Au(III) derivatives with PhICl2 or Br2 proved impossible for the primary amine derivatives [although isopropylamine-trichloridogold(III) was obtained unexpectedly from the corresponding cyanide] and unsatisfactory for the secondary amine derivatives. Products LAuX3 and [L2AuX2]+[AuX4]− were identified but were formed in disappointing yields. In isolated cases protonated products (LH)+[AuCl4]−, (LH+)3[AuCl4]−(Cl−)2 or [(Et2N)2CH]+[AuBr4]− were formed, presumably by involvement of the dichloromethane solvent and/or adventitious water. Here also the yields were poor, and some products arose as mixtures. Direct reaction of amines with AuCl3 or (tht)AuX3 was also unsuccessful. All products were characterized by X-ray structure analysis.

Abstract
We report here on a custom-built time-correlated single photon-counting (TCSPC)-based fluorescence lifetime imaging microscopy (FLIM) setup with a continuously tunable white-light supercontinuum laser combined with acousto-optical tunable filters (AOTF) as an excitation source for simultaneous excitation of multiple spectrally separated fluorophores. We characterized the wavelength dependence of the white-light supercontinuum laser pulse properties and demonstrated the performance of the FLIM setup, aiming to show the experimental setup in depth together with a biomedical application. We herein summarize the physical-technical parameters as well as our approach to map the skin uptake of nanocarriers using FLIM with a resolution compared to spectroscopy. As an example, we focus on the penetration study of indocarbocyanine-labeled dendritic core-multishell nanocarriers (CMS-ICC) into reconstructed human epidermis. Unique fluorescence lifetime signatures of indocarbocyanine-labeled nanocarriers indicate nanocarrier-tissue interactions within reconstructed human epidermis, bringing FLIM close to spectroscopic analysis.
Internal Morphology of Cracking of Two 3-D Pre-Existing Cross-Embedded Flaws under Uniaxial Compression

Abstract
This paper studies the internal morphology of cracking of two 3-D pre-existing cross-embedded flaws in poly(methyl methacrylate) specimens under uniaxial compression. In this study, observable cracking behaviors include the crack initiation, growth, wrapping and coalescence, and the ultimate fracture of the specimen. The experimental results show six modes of crack initiation and two types of crack wrapping. The initiation of silky cracks in 3-D cracking behaviors is reported first, as well as the closed-mode wrapping of petal cracks. Substantial wrapping of petal cracks, which plays an important role in crack coalescence, appears to be the major difference between the 2-D and 3-D cracking behaviors of pre-existing flaws. Moreover, three modes of crack coalescence, which include the coalescence of petal cracks, antiwing cracks, and oblique secondary cracks, are found. Crack coalescence is predominantly created by the linkage of petal cracks, which is further classified into six categories. Note that only limited vertical growth of petal cracks is observed, and the ultimate failure of specimens is induced by the continued growth of the propagated wing crack. It was found that the ultimate fracture face of the specimens consists of continuous wing cracks and fragmented silky cracks. This paper provides the internal morphology basis for the 3-D fracture mechanism of specimens containing two 3-D pre-existing cross-embedded flaws.
Relationship between spousal education gaps and life satisfaction: Evidence from Canada
Authors: Latif Ehsan 
Published: January 2018

This study uses Canadian data from the General Social Survey (Cycle 25:2011) to examine the impact of a spousal education gap on males’ and females’ life satisfaction. The study finds that a spousal education gap, whether positive or negative, does not have any significant impact on males’ and females’ life satisfaction. To further investigate these issues, the study divided the sample into two groups based on age categories: those below age 55 and those at or above age 55. The spousal education gap has an insignificant impact on life satisfaction in both of these groups.

Published: January 2018

Background. Complications after microsurgical toe-to-hand transfer is a problem for which there is no common approach to treatment.
The aim of this study was to analyze the ischemic complications after microsurgical operations in children with pathologies of the hand to improve the quality of surgical treatment.
Materials and methods. From 2007 to 2016, we performed 210 microsurgical toe-to-hand transfers involving 306 transplants, 267 (87.3%) of which were performed in patients with congenital pathologies and 39 (12.7%) in patients with post-traumatic deformities of the hand. In total, 352 fingers were reconstructed.
Results. Blood supply disturbance following toe transplants occurred in 19 (6.2%) of the 306 transplants, most often in the early postoperative period (73.7%). The main cause of microcirculatory disorders was thrombosis of the venous or arterial trunks (8 cases). In 6 patients, the blood supply disturbance occurred because of thrombosis of autovenous grafts. Two patients underwent necrectomy at days 7 and 18 because conservative and operative treatments were not successful.
Conclusion. The treatment method of choice after the first appearance of signs of blood supply disturbance in a transferred toe is conservative therapy, which includes disaggregants, anticoagulants, and hirudotherapy. Conservative therapy should be performed within 3 hours from the beginning of ischemia; if ischemia is absent, the patient must undergo surgery. The operation includes soft tissue decompression, mechanical pumping across vascular anastomoses, and if necessary, excision of the abnormal vessel part with subsequent autoplasty.

Background. Birth head trauma causing intracranial injury is one of the most common causes of neonatal mortality and morbidity. In case of suspected cranial fractures and intracranial hematomas, diagnostic methods involving radiation, such as x-ray radiography and computed tomography, are recommended. Recently, an increasing number of studies have highlighted the risk of cancer complications associated with computed tomography in infants. Therefore, diagnostic methods that reduce radiation exposure in neonates are important. One such method is ultrasonography (US).
Aim. We evaluated US as a non-ionizing radiation method for diagnosis of cranial bone fractures and epidural hematomas in newborns with cephalohematomas or other birth head traumas.
Material and methods. The study group included 449 newborns with the most common variant of birth head trauma: cephalohematomas. All newborns underwent transcranial-transfontanelle US for detection of intracranial changes and cranial US for visualization of bone structure in the cephalohematoma region. Children with ultrasonic signs of cranial fractures and epidural hematomas were further examined at a children’s hospital by x-ray radiography and/or computed tomography.
Results and discussion. We found that cranial US for diagnosis of cranial fractures and transcranial-transfontanelle US for diagnosis of epidural hematomas in newborns were highly effective. In newborns with parietal cephalohematomas (444 children), 17 (3.8%) had US signs of linear fracture of the parietal bone, and 5 (1.1%) had signs of ipsilateral epidural hematoma. Epidural hematomas were visualized only when US was performed through the temporal bone and not by using the transfontanelle approach. Sixteen cases of linear fractures and all epidural hematomas were confirmed by computed tomography.
Conclusion. The use of US diagnostic methods reduced radiation exposure in newborns with birth head trauma. US methods (transcranial-transfontanelle and cranial) can be used in screening for diagnosis and personalized monitoring of changes in birth head trauma as well as to reduce radiation exposure.

Published: January 2018

Introduction. The modern approach to the treatment of unstable fractures of the thoracolumbar and lumbar spine in children is surgical stabilization at the early stages after trauma by using metal structures that quickly restore vertical functionality to the patient and shorten the period of inpatient treatment. However, the issues related to restorative treatment have not been sufficiently addressed.
Aim. To develop an algorithm for restorative treatment of children at the inpatient stage after surgical treatment of unstable uncomplicated fractures of the thoracolumbar and lumbar spine.
Material and methods. Based on the results of treatment of 73 patients aged 9 to 17 years with unstable uncomplicated vertebral fractures, an algorithm of stage-by-stage rehabilitation by means of therapeutic gymnastics depending on the severity of the injury, method of surgical stabilization of the spine, physical condition of the child, and time passed after the operation was developed.
Results and discussion. The use of differentiated groups of respiratory gymnastics and isometric and dynamic exercises for muscle groups restored vertical functionality to patients in 1–3 days after surgery, restored spine and motor functions, and shortened the duration of inpatient treatment to a range of 10–14 days.
Conclusion. The developed algorithm for physical rehabilitation of children after surgical treatment of unstable injuries of the thoracic and lumbar spine by using metal structures at the inpatient stage contributed to the selection of the most rational and effective program of restorative treatment.
Demand Forecast of 700 MHz Frequency Spectrum for LTE Mobile Broadband Services [Prakiraan Kebutuhan Spektrum di Frekuensi 700 MHz untuk Layanan Broadband Mobile LTE]
Authors: Aryaguna Priambada , Iskandar Iskandar 
Published: January 2018

Spektrum frekuensi 700 MHz merupakan salah satu kandidat spektrum untuk layanan LTE di Indonesia. Pada awalnya spektrum ini digunakan untuk siaran televisi analog. Setelah periode peralihan digital, ada potensi 108 MHz bandwith yang dapat digunakan akibat transformasi penyiaran ke TV digital dan kemudian disebut digital dividen. Pada penelitian ini, sebuah model pertumbuhan digunakan untuk memperkirakan kebutuhan spektrum frekuensi untuk LTE. Makalah ini membahas perhitungan kebutuhan spektrum untuk frekuensi untuk layanan LTE dalam parameter seperti kepadatan penduduk, jenis area dimana LTE digunakan, dan penetrasi pelanggan. Kami menggunakan model difusi Bass untuk menghitung kebutuhan spektrum di jaringan LTE. Dalam penelitian ini ada dua kandidat spektrum frekuensi yang dapat digunakan, namun dengan karakteristik dan permasalahannya sendiri. Untuk spektrum di bawah 1 GHz, ada bandwith 25 MHz di kisaran spektrum frekuensi 800 MHz yang masih digunakan untuk layanan CDMA sampai saat ini. Spektrum 900 MHz juga memiliki bandwith 25 MHz, namun tetap digunakan untuk layanan GSM. Spektrum frekuensi lainnya, 1900 MHz dan 2100 MHz masing-masing lebar 26 dan 60 MHz, masih digunakan untuk teknologi WCDMA dan penggunaannya masih sangat tinggi *****Frequency spectrum of 700 MHz is one of many candidates for LTE service establishment in Indonesia. At first, this spectrum is used for analog TV broadcasting. After the digital switchover period, there is 108 MHz bandwidth left because of the digital broadcasting transformation which called by digital dividend. A certain growth model is used to demand forecast the frequency spectrum needed for this digital dividend LTE. This paper aims to calculate the spectrum needs for the LTE services within a certain parameter, such as population density, type of area in which LTE is deployed, and subscriber penetration. We used Bass diffusion model to calculate the spectrum needs in LTE network. There are two frequency spectrum candidates which can be used with its own characteristics and problems. For spectrums below 1 GHz, there is a bandwidth of 25 MHz in the range 800 MHz frequency spectrum that is still used for CDMA services. The 900 MHz spectrum also has a bandwidth of 25 MHz and still used for GSM service. Another spectrum i.e. 1900 MHz and 2100 MHz, each of that have the width of 26 and 60 MHz, and still used for WCDMA technology with high utilization

Objectives: The aim of this study was to examine patterns of troponin testing in the emergency department of a large tertiary care hospital in Oman and to determine its effect on patient management, including length of hospital stay (LOS). Methods: This retrospective study analysed the medical records of all adult patients undergoing troponin testing in the emergency department of the Sultan Qaboos University Hospital, Muscat, Oman, during the month of July 2015. Patients who presented with an ST-elevation myocardial infarction wereexcluded. Results: A total of 4,845 patients attended the emergency department during the study period; of these, troponin tests were ordered for 588 patients. The majority of the patients had negative troponin test results (81.3%). Chest pain, palpitations and breathlessness were the most common presenting complaints for those with positive troponin results. However, 41.8% of patients did not have any cardiac symptoms. Individuals with positive troponin tests had a significantly longer LOS compared to those with negative tests (mean: three versus one day; P = 0.001). In total, only 28.2% of those with positive troponin test results had final diagnoses associated with a cardiac condition, such as heart failure, an acute coronary syndrome (ACS), atrial fibrillation or other types of arrhythmia. Conclusion: A positive troponin test was associated with increased LOS; however, only a small proportion of these patients had a final diagnosis associated with a cardiac condition. Guidelines should be provided to ensure that troponin testing is performed only in cases where an ACS is suspected.

Published: January 2018

Objectives: While several factors have been shown to influence operating room (OR) turnaround times, few comparisons of planned and actual OR turnaround times have been performed. This study aimed to compare planned and actual OR turnaround times at a large rural hospital in Northern Germany. Methods: Thisretrospective study examined the OR turnaround data of 875 elective surgery cases scheduled at the Marienhospital, Vechta, Germany, between July and October 2014. The frequency distributions of planned and actual OR turnaround times were compared and correlations between turnaround times and various factors were established, including the time of day of the procedure, patient age and the planned duration of the surgery. Results: There was a significant difference between mean planned and actual OR turnaround times (0.32 versus 0.64 hours; P <0.001). In addition, significant correlations were noted between actual OR turnaround times and the time of day of the surgery, patient age, actual duration of the procedure and staffing changes affecting the surgeon or the medical specialty of the surgery (P <0.001 each). The quotient of actual/planned OR turnaround times ranged from 1.733–3.000. Conclusion: Significant discrepancies between planned and actual OR turnaround times were noted during the study period. Such findings may be potentially used in future studies to establish a tool to improve OR planning, measure OR management performance and enable benchmarking.
Soft Tissue Rosai-Dorfman Disease: Case report
Authors: Rajib Rubyath C. , Pillai Rajasekharan , Sulaiman Ibrahim A. , Al-Haddabi Ibrahim 
Published: January 2018

Rosai-Dorfman disease (RDD) is a rare benign proliferative histiocytic disorder characterised by massive lymphadenopathy. While extranodal involvement can occur in generalised RDD, isolated soft tissue RDD (STRDD) is extremely rare. We report a 17-year-old male patient who presented to the maxillofacial outpatient department of the Sultan Qaboos Hospital, Salalah, Oman, in 2015 with a painless cheek mass which had been slowly growing over the previous two months. Routine histopathological examinations and immunohistochemistry confirmed a diagnosis of STRDD. Currently, surgical excision is considered to be the most effective curative treatment for STRDD, as the outcomes of other treatment modalities are still unknown. Despite its rarity, STRDD should be considered in the differential diagnosis of histiocytic soft tissue lesions.
Pitting Oedema in a Patient with Lumbar Disc Herniation: Case report of an unusual association
Authors: Sadeghian Homa , Motiei-Langroudi Rouzbeh 
Published: January 2018

Oedema refers to the excessive accumulation of fluid within intercellular tissues as a result of disequilibrium between the capillary hydrostatic and oncotic pressure gradients. Lumbar disc herniation (LDH) commonly causes lower back pain and radicular leg pain. We report a 57-year-old female who presented to the neurosurgery clinic of the Bam University of Medical Sciences, Bam, Iran, in 2015 with pain and pitting oedema in the bilateral lower extremities. Magnetic resonance imaging confirmed a diagnosis of LDH of the L3–L4 and L4–L5 vertebrae. The patient subsequently underwent a bilateral laminotomy and foraminotomy of the involved vertebrae to relieve her pain. Following the surgery, there was a complete resolution of the LDH-related symptoms as well as the oedema. Although LDH has never before been associated with oedema, it may nevertheless cause lower limb oedema in exceptional and rare cases, as highlighted in this patient.

Published: January 2018

Lipoleiomyomas are an extremely rare form of uterine leiomyoma; moreover, the occurrence of this type of tumour on the broad ligament is even rarer. We report two cases of broad ligament lipoleiomyomas in 15- and 38-year-old female patients who presented to the Lok Nayak Jai Prakash Hospital in New Delhi, India, between 2016 and 2017. In both cases, the preoperative diagnosis was of a solid ovarian malignancy. Most broad ligament tumours are mistaken for ovarian masses as they are difficult to diagnose radiologically.
Pragmatismo ético e social: cultura, desenvolvimento e humanismo
Authors: Vogt Carlos 
Published: January 2018

Num mundo de economia globalizada, de um pragmatismo financeiro a toda prova, de um finalismo utilitarista sem precedentes, de uma violência urbana e de uma urbanização da violência incomuns cabe ainda a oposição, presente em várias línguas e que remonta à antiguidade clássica, entre cidade (civitas, polis) e campo (rus, silva) como topônimos analógicos de civilizado, polido em oposição à rústico e inculto? É possível, apesar dos estudos de Walter Benjamin, continuar a crer que a aliança da cultura e da civilização, que os povos latinos batizaram de humanismo, retomará o seu vigor explicativo e a força de seu poder positivo de transformação, de desenvolvimento e de aperfeiçoamento da sociedade? É possivel continuar a conceder este equilibrio harmonioso, caro aos humanistas, entre os elementos da tradição nacional e os da tradição humana, isto é, entre as culturas nacionais e a universalidade da cultura? É em torno dessas e de outras questões correlatas que se constrói o presente texto.
