Authors: Zhang Yong , Fang Yao , Jin Baosheng , Zhang Youwei , Zhou Chunlei , Sher Farooq 
Published: February 2019

Abstract
Numerical investigations of an anti-corrosion design and the combustion process (original conditions and optimal conditions) were conducted for a 660 MW opposed wall fired boiler. In order to solve high-temperature corrosion of the side wall, a scheme was proposed: slotting in the side wall and introducing air (closing-to-wall air) from the secondary air. The effect of anti-corrosion was disclosed in detail by varying the structures of slotting, gas velocities from nozzles and jet inclination angles. The temperature and NOx distribution in the furnace at optimized conditions were compared with those at the original operating conditions. Simulation results showed that the structures of the slot and gas velocities from the nozzles had a marked effect on anti-corrosion of the side wall. When the gas velocity was 4 m/s, an inclination angle of the gas velocity was not conducive to anti-corrosion of the side wall. When the gas velocity increased at the middle and bottom of the side wall, the anti-corrosion effect increased significantly. When the optimal scheme was adopted, the corrosion area of the side wall decreased obviously, but the furnace temperature and the NOx emission increased slightly. The detailed results of this work promote a full understanding of closing-to-wall air and could help to reduce the corrosive area in pulverized-coal furnaces or boilers.

Published: February 2019

Abstract
Many countries adopted legal regulation of insolvency problems of insurers and rules for bankruptcy proceedings (insolvency) to mitigate and prevent consequences of bankruptcy and preserve the assets of insurance companies. To a certain extent, Ukraine follows the similar track. The authors describe the specifics of bankruptcy proceedings, defined by the laws of Ukraine on bankruptcy, and “complicated” by the legal status of the insurance company. On the basis of the analysis, the authors put forward a proposal to modernize bankruptcy law as part of the legal regulation of bankruptcy of insurers-debtors (bankrupts). It is established that the Law of Ukraine of 1992 provides for the possibility of applying a procedure of sanation to the insurers. The authors state that the specific legal consequences of the liquidation procedure and the recognition of a debtor as a bankrupt include the termination of all insurance contracts and sale of property. It has been established that the incoherence of bankruptcy laws of different countries is explained by different approaches to legal regulation.
A Joint Multicast Optimization Approach for QoS Provisioning in Optical Label Switching (OLS) Networks
Authors: Khlifi Yassine , Alotaibi Majid 
Published: February 2019

Abstract
Optical label switching is introduced for ensuring fast data transfer, quality of service (QoS) support, and better resource management. However, the important issue is how to optimize resource usage and satisfy traffic constraints for improving network performance and design. This paper proposes a dynamic approach that optimizes the resource in terms of link capacity and FDL (fiber delay line) buffering as well as a wavelength converter. The proposed approach decreases the resources usage and guarantees QoS support for various traffic demands. The optimization strategy consists of two stages: path building and traffic management. The path building assures logical topology making using the cumulative cost of available resource and traffic requirements including unicast and multicast. The traffic management solves the resource formulation problem during the traffic transfer by guaranteeing the required loss and blocking delay. Simulation work is conducted for validating the proposed approach and evaluating its performances and effectiveness. Simulation results show that our proposal minimizes effectively the use of link capacity of lightpath and light-tree. Moreover, our approach optimizes the use of buffering capacity and wavelength converter and guarantees QoS support according to traffic requirements.

Published: February 2019

Abstract

Background
There is little information on which to base the prognostic counselling as to whether an antenatally diagnosed fetal abdominal cyst will grow or shrink, or need surgery. This study aims to provide contemporary data on prenatally diagnosed fetal abdominal cysts in relation to their course and postnatal outcomes.

Methods
Fetal abdominal cysts diagnosed over 11 years in a single centre were identified. The gestational age at diagnosis and cyst characteristics at each examination were recorded (size, location, echogenity, septation and vascularity) and follow-up data from postnatal visits were collected.

Results
Eighty abdominal cysts were identified antenatally at 28+4 weeks (range 11+0–38+3). Most (87%) were isolated and the majority were pelvic (52%), simple (87.5%) and avascular (100%). Antenatally, 29% resolved spontaneously; 29% reduced in size; 9% were stable and 33% increased in size. Forty-one percent of cysts under 20 mm diameter increased in size, while only 20% of cysts with a diameter of over 40 mm increased in size. The majority of cysts were ovarian in origin (n=45, 56%), followed by intestinal (n=15, 18%), choledochal (n=3, 4%), liver (n=2, 3%) and renal/adrenal origins (n=2, 3%), respectively. In 16% (n=13), the antenatal diagnosis was not obvious. Seventy-five percent of the cysts that persisted postnatally required surgical intervention.

Conclusion
Most antenatally diagnosed fetal abdominal cysts were ovarian in origin. Though most disappeared antenatally, nearly three quarters required surgical intervention when present after birth. Cysts of intestinal origin are more difficult to diagnose antenatally and often require surgery.

Abstract

Objective
Detection of JAK2 V617F in myeloproliferative neoplasms (MPNs) is very important in both diagnosis and disease progression. In our study, we investigated the frequency of JAK2 V617F mutation in patients with myeloproliferative disorders.

Methods
We retrospectively reviewed the records of 720 patients (174 females and 546 males) who were tested for JAK2 V617F mutation from January 2007 to December 2017.

Results
In our patients were determined 22.6% JAK2 V617F mutation. 33.3% in women, 19.2% in men have been positive for JAK2 V617F mutation. In our study JAK2 V617F present in 48.6% of essential thrombocythemia, 80.5% of polycythemia rubra vera (PV), 47.5% of primary myelofibrosis, 10% of MPNs, unclassifiable, 0.8% of others. We also investigated the difference in hematological parameters [white blood cell, hemoglobin (Hb), hematocrit (HCT), red blood cell distribution widths (RDW) and platelets count (PLT)] between JAK2 V617F positive and JAK2 V617F negative patients.

Conclusions
Investigation of the JAK2 V617F mutation is very important in cases of MPNs. In our study JAK2 V617F mutation was higher in PV, essential thrombocythemia, and primary myelofibrosis patients. However, there were significant differences in Hb, HCT, RDW and PLT levels in mutation-positive patients.
An X-Ray, Raman and IR Study of α-CsReO4, the High-Temperature Modification of Cesium Perrhenate
Authors: Range Klaus-Jürgen , Rögner Peter , Anton M. Heyns , Linda C. Prinsloo 
Published: February 2019

Cesium perrhenate undergoes a reversible phase transition from the orthorhombic room-temperature
phase (β-CsReO4, space group Pnma) to a tetragonal high-temperature phase
(α-CsReO4). The space group of α-CsReO4 was unambiguously confirmed by high-temperature
X-ray diffraction to be I41/amd in contrast to the earlier literature, in which space group
I41/a (and hence, a scheelite type structure) was assumed for α-CsReO4. From a data set obtained
at 468 K the crystal structure of α-CsReO4 (a = 5.9607(4), c = 14.446(1)Å, Z = 4) was
refined to R = 0.032, Rww = 0.029 using anisotropic displacement factors.In the vibrational spectra not all of the predicted com ponents for β-CsReO4 could be confirmed
by the experiments, but for α-CsReO4 very good agreement was obtained between the
predicted and observed bands. The fact that v2 at ~ 300 cm–1 is not observed in the IR spectra
of α-CsReO4 confirms the space group I41/amd, since, under I41/a symmetry, this band is
allowed.The structure of α-CsReO4 consists of isolated ReO4 tetrahedra which are linked together by
cesium atoms. The relationships between the scheelite, α-CsReO4 and β-CsReO4 structural
types are discussed.
A Wood Recovery Assessment Method Comparison between Batch and Cellular Production Systems in the Furniture Industry

Published: February 2019

Abstract
Enhanced wood recovery mirrors a successful wood manufacturing operation. Studies of wood recovery in secondary wood processing, however, are scarce, particularly in furniture manufacturing. Although recovery rates are under the continuous surveillance of sophisticated technology, this attempt to monitor wood recovery would be especially challenging for small- to medium-sized furniture enterprises, as the capital investment in such technology would be substantial. This would hinder the possibility for improvements in production efficiency of the furniture industry. A methodology of wood recovery assessment in the furniture industry has been developed and proposed but has not been validated with a cellular production system, a different layout process and distinctive machinery, species, and other customer requirements. The objective of this study is to assess the wood recovery protocol individually used in batch and cellular production systems, followed by examining the wood recovery of furniture manufacturing in these distinct production systems. Two Indonesian medium-sized furniture companies that individually operate batch and cellular production systems were employed, and two methods, mass and volume, were used to assess wood recovery at each furniture-making station. There was a significant difference in cumulative wood recovery rates between batch and cellular production systems. Based on species and product dimensions, the average individual and cumulative wood recovery rates of furniture manufacturing resulted in a significant difference at the resawing and edging station. Large-dimension product recorded higher wood recovery level than small-dimension product. The wood recovery rates at the resawing and edging, surface planing, thickness planing, and trimming stations were mostly influenced by species, the quality of sawn timber, and cutting bills. Meanwhile, wood recovery at other stations was affected by product dimension and design. The mass method was the most acceptable method according to the measurement systems analysis.

Published: February 2019

El artículo muestra algunos resultados derivados de una investigación acerca de los procesos de formación de educadores en la Fundación Universitaria Monserrate de la ciudad de Bogotá. Estos responden a los siguientes cuestionamientos: cómo las representaciones acerca de la praxis pedagógica de los docentes que participan en los procesos de formación de licenciados, están mediadas por elementos y discursos diversos, referidos a la política educativa colombiana y el marco normativo que se establece para la calidad ofrecida por las instituciones de educación superior en materia de formación docente y, cómo esto se coloca en tensión con elementos que articulan la relación entre práctica, reflexión e investigación como modo de producción de conocimiento pedagógico, aspecto denominado praxis pedagógica.En consecuencia, la investigación se propuso identificar, desde una apuesta metodológica basada en el enfoque cualitativo, los elementos asociados a las representaciones de praxis pedagógica presentes en los procesos de formación docente, empleando una metodología hermenéutica. Los resultados evidencian que la praxis se concibe como un modo de ejercitar el pensamiento y construir saber pedagógico a partir de contextos situados que transforman la práctica educativa, mediada por la reflexión constante acerca de la experiencia educativa.
Lost in Translation: On the Problem of Data Coding in Penalized Whole Genome Regression with Interactions
Authors: Martini Johannes W R , Rosales Francisco , Ha Ngoc-Thuy , Heise Johannes , Wimmer Valentin , Kneib Thomas 
Published: February 2019

Abstract
Mixed models can be considered as a type of penalized regression and are everyday tools in statistical genetics. The standard mixed model for whole genome regression (WGR) is ridge regression best linear unbiased prediction (RRBLUP) which is based on an additive marker effect model. Many publications have extended the additive WGR approach by incorporating interactions between loci or between genes and environment. In this context of penalized regressions with interactions, it has been reported that translating the coding of single nucleotide polymorphisms -for instance from -1,0,1 to 0,1,2- has an impact on the prediction of genetic values and interaction effects. In this work, we identify the reason for the relevance of variable coding in the general context of penalized polynomial regression. We show that in many cases, predictions of the genetic values are not invariant to translations of the variable coding, with an exception when only the sizes of the coefficients of monomials of highest total degree are penalized. The invariance of RRBLUP can be considered as a special case of this setting, with a polynomial of total degree 1, penalizing additive effects (total degree 1) but not the fixed effect (total degree 0). The extended RRBLUP (eRRBLUP), which includes interactions, is not invariant to translations because it does not only penalize interactions (total degree 2), but also additive effects (total degree 1). This observation implies that translation-invariance can be maintained in a pair-wise epistatic WGR if only interaction effects are penalized, but not the additive effects. In this regard, approaches of pre-selecting loci may not only reduce computation time, but can also help to avoid the variable coding issue. To illustrate the practical relevance, we compare different regressions on a publicly available wheat data set. We show that for an eRRBLUP, the relevance of the marker coding for interaction effect estimates increases with the number of variables included in the model. A biological interpretation of estimated interaction effects may therefore become more difficult. Consequently, comparing reproducing kernel Hilbert space (RKHS) approaches to WGR approaches modeling effects explicitly, the supposed advantage of an increased interpretability of the latter may not be real. Our theoretical results are generally valid for penalized regressions, for instance also for the least absolute shrinkage and selection operator (LASSO). Moreover, they apply to any type of interaction modeled by products of predictor variables in a penalized regression approach or by Hadamard products of covariance matrices in a mixed model.

Published: February 2019

La inducción artificial de la poliploidía es una técnica de fitomejoramiento empleado en plantas de interés medicinal. Sin embargo, pocas especies del género Aloe han sido sometidas a este tratamiento. El objetivo de esta investigación fue estandarizar la técnica de inducción de poliploidía en vitroplantas de Aloe vera (L.). Se realizó un diseño experimental con dos grupos (control y experimental) a los cuales se les aplicó un estudio citogenético pre y postratamiento por tres generaciones consecutivas. Se evaluaron tres concentraciones de colchicina (0,05; 0,10 y 0,15%) y dos tiempos de exposición (48 y 72 horas). Las vitroplantas controles mantenidas en agua destilada (sin colchicina) por 48 y 72 (T1 y T2 respectivamente) y las tratadas con solución de colchicina al 0,05% por 48 y 72 horas (T3 y T4 respectivamente), presentaron pocos cambios citogenéticos, siendo la mayoría de sus células diploides. Las plantas tratadas con solución de colchicina a 0,10% por 48 y 72 horas (T5 y T6 respectivamente), lograron la duplicación cromosómica en más del 50% del tejido. Las tratadas con una concentración de 0,15% por 48 horas (T7) mostraron tejido quimérico con un alto predominio de células poliploides y al aumentar el tiempo de exposición a 72 horas (T8), todas las células fueron poliploides, pero el desarrollo de estas plantas in vitro, fue anormal y con tejido necrótico. Las plantas con T5, se desarrollaron mejor que con el T6. Se recomienda el uso de la colchicina a una concentración de 0,10% por 48 horas para obtener vitroplantas poliploides en A. vera

Total Lesion Glycolysis on 18F-FDG PET/CT of Women with Non-Locally Advanced Breast Cancer: Does it Correlate with CT Density of the Lesion?
Authors: COŞAR AYAZ Sevin 
Published: February 2019

Objective:
Breast cancer (BC) is the second most frequent malignancy in women. Fluorine-18-fluorodeoxyglucose
(18F-FDG) positron emission tomography
(PET)/computed tomography (CT)
has become a major diagnostic tool for staging of the disease and
predicting the prognosis. We aimed to
evaluate the correlation between main quantitative 18F-FDG
PET/CT parameters- primarily TLG
(total lesion glycolysis), and CT density measurements as Hounsfield Unit (HU) of the primary BC masses in non-locally advanced BC (non-LABC)
patients. And also we aimed to see whether there is a correlation between the
volume and HU measurements of BC masses in non-LABC patients. Methods:
In this retrospective study, we included 17 women with unilateral non-LABC having
a mean age of 54.1±10.3 years who underwent 18F-FDG PET/CT before any treatment between
2016−2017. The mean volume, HU, maximum standardized uptake value (SUVmax) and
TLG of the primary BC masses with their standard
deviations and 95% confidence intervals (CI)s were calculated. Of the BC masses, the
correlations between their mean TLG and mean HU, their mean SUVmax and mean HU,
their mean volume and mean HU were statistically calculated.Results:
The
mean volume and HU of BC masses were 4.6±3.9 mL
(95% CI: 2.6−6.6) and 42.5±4.1 HU (95% CI: 40.3−44.6), respectively. The
mean SUVmax and TLG of BC masses were 6.4±5.6 g/mL (95%
CI: 3.5−9.3) and 22.1±14.2 g/mLxmL (95% CI:
14.7−29.4), respectively. Of the BC masses, the correlations between
their mean TLG and mean HU (r=-0.443, P=0.075),
besides their mean SUVmax and mean HU (r=-0.368, P=0.146) were not
statistically significant. The correlation between the mean
volume and the mean HU of BC masses was also statistically insignificant (r=-0.214, P=0.410).

Conclusion:
In women with non-LABC, 18F-FDG PET/CT is a useful and reliable tool
for obtaining the TLG of primary BC masses presenting with various CT densities.

ÖZ Postmodernizmin
eleştirel söylemi olan yapıbozum, felsefi bir konum olmaktan ziyade pek çok

Post-yapısalcı düşünür Jacques Derrida'nın geliştirdiği bu yöntem, ikili
karşıtlıklar üzerine kurgulanmış tüm yapılardaki çelişkileri deşifre ederek

Ön-Rönesans Dönemi Resim Sanatının Özellikleri ve Temsile Dönük Çağdaş Resim Sanatı Üzerindeki etkileri

Published: February 2019

Ön-Rönesans
dönemi, Rönesansa giden yolda doğal gerçekliğin akla uygun betimlenmesi
açısından sancılı bir süreçtir. Doğanın perspektif aracılığıyla iki boyutlu
düzleme aktarılmasında yaşanan sıkıntılar, oylumlamada iki boyutluluk hissinin
tam olarak aşılamaması ve hala Ortaçağ sanatının sembolik dilinin varlığını
sürdürüyor olması buna neden olan etmenlerdir. Ama bu ikircikli sonuçlar bu
dönem resimlerinin karakteristik özellikleridir ve güçlerini, samimiyetlerini,
referans olma özelliklerini de bu niteliklerinden alırlar. Rönesans’ın olgun
dönemindeki kazanımlar zamanla akademilerde tartışmasız bir öğreti haline
gelir. Teknik yetkinlikle yapılan mekanik tekrarlar sanatın yüzeyselleşmesine, samimiyetinin ve
yaşamsallığının kaybolmasına neden olur. Akademik sanata gösterilen tepkiler
sonucunda ön-Rönesans resimleri ilgi görmeye başlar ve bu ilgi ilk ortaya
çıktığından çağımıza kadar temsile ve figürasyona yönelen her sanat hareketinde
varlığını ortaya koyar.
