Effect of Slot Wall Jet on Combustion Process in a 660 MW Opposed Wall Fired Pulverized Coal Boiler
Authors: Zhang Yong , Fang Yao , Jin Baosheng , Zhang Youwei , Zhou Chunlei , Sher Farooq
Published: February 2019

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

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

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

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.

Published: February 2019

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
Authors: Prasetyo Vendy E. , Belleville Benoit , Ozarska Barbara , Mo John P. T.
Published: February 2019

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.

Participatory Modeling (PM) is becoming increasingly common in environmental planning and conservation, due in part to advances in cyberinfrastructure as well as to greater recognition of the importance of engaging a diverse array of stakeholders in decision making. We provide lessons learned, based on over 200 years of the authors’ cumulative and diverse experience, about PM processes. These include successful and, perhaps more importantly, not-so-successful trials. Our collective interdisciplinary background has supported the development, testing, and evaluation of a rich range of collaborative modeling approaches. We share here what we have learned as a community of participatory modelers, within three categories of reflection: a) lessons learned about participatory modelers; b) lessons learned about the context of collaboration; and c) lessons learned about the PM process. First, successful PM teams encompass a variety of skills beyond modeling expertise. Skills include: effective relationship-building, openness to learn from local experts, awareness of personal motivations and biases, and ability to translate discussions into models and to assess success. Second, the context for collaboration necessitates a culturally appropriate process for knowledge generation and use, for involvement of community co-leads, and for understanding group power dynamics that might influence how people from different backgrounds interact. Finally, knowing when to use PM and when not to, managing expectations, and effectively and equitably addressing conflicts is essential. Managing the participation process in PM is as important as managing the model building process. We recommend that PM teams consider what skills are present within a team, while ensuring inclusive creative space for collaborative exploration and learning supported by simple yet relevant models. With a realistic view of what it entails, PM can be a powerful approach that builds collective knowledge and social capital, thus helping communities to take charge of their future and address complex social and environmental problems.
II. From Following in Padres’ Footsteps to Confronting Sugar Cubes
Authors: Casey Mary
Published: February 2019

Mary Casey's essay on mission history traces the tendency of early SCQ articles, in parallel with contemporaneous educational standards and cultural productions, to idealize the padres' work and romanticize the mission era, a trend that persisted into the late 1960s. It was only at that point that a more critical appraisal emerged. Critical analysis and new methodologies revealed the padres' ill treatment of Indigenous peoples, the mission system's role in imperial conquest, and the mission plants as instruments of control. The multiple perspectives and interactions of multiple groups of historical actors placed in the context of a wider borderlands in the recent articles in the Southern California Quarterly extend California history from a California-exceptionist mold into a richer understanding of continental history.

Representaciones de praxis pedagógica en el marco de los procesos de formación docente. Caso Unimonserrate-Colombia
Authors: González Riveros Ada Marcela , Pinzón González Diego Andrés , Cruz Cesar Augusto
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

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.
Assessment of the Depression-Level Effectiveness of the Curse Words in Young Adults in Private Co-Educational Pharmaceutical Institutions in Pune University Pharmaceutical Institutions Living With Poor Sanitation, India: A Pre-planned, Causal-Pathway-Based Analysis
Authors: Hajare Rahul
Published: February 2019

Depression and substance abuse is on the increase all over the world. The poor and the rich are also involved in this dangerous habit that has impact not only on reproductive health but also has an impact on family, society, increase in health care expense and increased criminal activity. Health care providers are more concerned with treating the victims and less concerned on its prevention. Pregnant women bear greater brunt and there is adverse pregnancy outcome. Low birth weight, preterm labour, increased in miscarriage and raised perinatal mortality is some of the adverse effects. Children of such parents are more likely to inherit this bad trait. Children living in abusive homes where drugs and alcohol abuse occur simultaneously are often deprived of more than just the basics of food and shelter. Depression is defined as, “Any act on the part of the husband, partner or family which causes physical, mental, social or psychological trauma to the woman and prevent sher from developing her personality.” Reason for the increase in depression violence are; urbanization, industrialization, growth of urban slums, co-education and co - working in offices and factories, modern movies, television, obscene and pornographic literature and decreasing religious restrictions.

Authors: Bucar Jimmy , Magallen Jerome
Published: February 2019

Religiosity in this study pertains to five dimensions, namely: public practice, private practice, religious experience, ideology, and intellectual dimensions. Service quality is defined as an overall judgment similar to attitude towards the service and is generally accepted as an antecedent of overall customer satisfaction. This study aimed to ascertain if religiosity, spirituality, and life satisfaction are predictors of service quality among 15 faculty members in Cawayanan National High School, Tubigon East District, Division of Bohol, Philippines, who held permanent teaching positions as of S.Y. 2015 – 2016. It utilized a descriptive-correlational research design through the survey method. The results of the findings revealed that the respondents were highly religious in four areas of religiosity: ideology, public practice, private practice, and religious experience as measured through CRS-15. They possessed High Spirituality levels and felt that they were "Very Close" to God. They also obtained Average Satisfaction in life as measured in the SWLS. The respondents showed a satisfactory level of service quality in the five areas of service quality (Reliability, Assurance, Tangibles, Empathy, and Responsiveness). Recommendations were proposed to translate the respondents’ high religiosity and spirituality levels into selfless service and commitment.
RESP: Relay Suitability-based Routing Protocol for Video Streaming in Vehicular Ad Hoc Networks
Authors: Hammood Omar A. , Nizam Mohd , Nafaa Muamer , Hammood Waleed A.
Published: February 2019

Video streaming in Vehicular Ad Hoc Networks (VANETs) is a fundamental requirement for a roadside emergency and smart video surveillance services. However, vehicles moving at a high speed usually create unstable wireless links that drop video frames qualities. In a high-density network, network collision between vehicles is another obstacle in improving the scalability of unicast routing protocols. In this paper, the RElay Suitability-based Routing Protocol (RESP) which makes a routing decision based on the link stability measurement was proposed for an uninterrupted video streaming. The RESP estimates the geographic advancement and link stability of a vehicle towards its destination only in the small region. To ensure the reliability while extending the scalability of routing, the relay suitability metric integrates the packet delay, collision dropping, link stability, and the Expected Transmission Count (ETX) in the weighted division algorithm, and selects a high-quality forwarding node for video streaming. The experimental results demonstrated that the proposed RESP outperformed the link Lifetime-aware Beacon-less Routing Protocol (LBRP) and other traditional geographical streaming protocols in providing a high packet delivery ratio and less packet delay with various network densities, and proved the scalability support of RESP for video streaming.
A Prediction Algorithm based on Markov Chains for finding the Minimum Cost Path in a Mobile WSNs
Authors: Montoya Germán A. , Donoso Yezid
Published: February 2019

In this paper we propose the usage of a prediction technique based on Markov Chains to predict nodes positions with the aim of obtain short paths at minimum energy consumption. Specifically, the valuable information from the mobility prediction method is provided to our distributed routing algorithm in order to take the best network decisions considering future states of network resources. In this sense, in each network node, the mobility method employed is based on a Markov model to forecast future RSSI states of neighboring nodes for determining if they will be farther or closer within the next steps. The approach is evaluated considering different algorithms such as: Distance algorithm, Distance Away algorithm and Random algorithm. In addition, with the aim of performing comparisons against optimal values, we present a mathematical optimization model for finding the minimum cost path between a source and a destination node considering all network nodes are mobile. This paper is an extended variant of [8].
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.

On the Generalized Baskakov Durrmeyer Operators
Authors: ULUSOY Gülsüm
Published: February 2019

The main object of this paper is to construct Baskakov Durrmeyer type operators such that their construction depends on a function ρ. Using the weighted modulus of continuity, we show the uniform convergence of the operators. Moreover we obtain pointwise convergence of B_{n}^{ρ} by obtaining Voronovskaya type theorem. All results show that our new operators are sensitive to the rate of convergence to f, depending on our selection of ρ.
Media, tegniek, en die vraag na menslike afstomping
Authors: Olivier B
Published: February 2019

Dit is geen oordrywing om te praat van die tyd waarin ons leef as een van media-oorheersing nie. Die blote feit dat die Amerikaanse president die samelewing op hol kan jaag deur middel van sy tydige en ontydige "tweets" is simptomaties hiervan, asook uitdrukking van wat Manuel Castells die "netwerk-samelewing" noem. Laasgenoemde is moontlik gemaak deur die tegnologiese rewolusie wat terugstrek tot by die uitvinding van die radio, en wat in die konstruksie van die internet gekulmineer het. Wat minder bekend is, is dat hierdie globale rewolusie 'n fundamentele verandering in mense se ervaring van tyd en ruimte meegebring het - wat Castells die "ruimte van vloei" en "tydlose tyd" noem. Kortweg: die menslike lewensfeer is deurgrondelik omvorm deur tegnologiese ontwikkelinge. Die vraag is egter - in die lig van sekere verskynsels waarop iemand soos onder andere Sherry Turkle wys - of hierdie toedrag van sake, wat vereis dat mense wat in die mediasfeer tuis wil wees tot die status van "digitale boorlinge" moet aspireer, nie onvermydelik gepaardgaan met 'n sekere affektiewe en intellektuele afstomping nie; waarop sy bevestigend antwoord. Hierdie vraag sou maklik as uitdrukking van tegnofobie gelees kon word, maar, soos Bernard Stiegler aantoon, is dit nie die geval nie. Enersyds, so meen Stiegler, lei die huidige tegniek, in die gewaad van mnemo-tegniese apparate soos slimfone, tablette en skootrekenaars (waardeur jy toegang verkry tot onder andere sosiale media), na wat hy "ver-idiotisering" noem. Andersyds kan - en moet - 'n mens leer hoe om hierdie "uitwendige memoriseringsapparate" vir wat hy "kritiese intensivering" noem aan te wend, ten einde die stryd teen die gevangeneming van mense (veral kinders) se "aandag" te kan wen. Per slot van sake, volgens Stiegler is skole (en mens sou sosiale media kon byvoeg) vandag die arena waar die stryd gevoer word vir die aandag van skoliere en studente deur die siniese gebruik van tegniek en media deur neoliberale kapitalisme, uitsluitlik met die oog op bemarking. Vervolgens word gepoog om hierdie problematiek in perspektief te stel.
