A two-dimensional finite-element study of flow in the transition zone between an ice sheet and an ice shelf

A numerical study has been carried out on the flow of ice in the transition zone between an ice sheet and an ice shelf. The study was motivated by the need for global ice-sheet-ice-shelf modelling to determine the characteristics of the transition zone. The problem is dealt with from an academic viewpoint, and the study especially focuses on two-dimensional vertical sharp transition zones. Stokes equations are solved using a finite-element method. Conclusions include: (1) in ice-sheet-ice-shelf modelling, each of the two components can be computed separately then linked by a jump-boundary condition [or the horizontal velocity; (2) as shown by studies on the response of an ice shelf to tidal forcing, the surface elevation/thickness ratio passes through the hydrostatic equilibrium value.
Epidemiology of aspergillosis in mainland China

Objective To understand the epidemiology of aspergillosis and the status of diagnosis and treatment in mainland China.Methods Literatures from January 1991 to October 2009 were collected by CNKI and Pubmed and statistically analyzed.Results A total of 1 447 cases were included in our study,in which 481 cases had microbiological evidences of aspergillus,258 cases did species identification with 153 strains of A.fumigatus. Pulmonary infection was presented in 1 047 cases.Etiological diagonosis depended on direct microspcopy and culture,while species identification relied on morphology except 4 cases with identification of molecular biology.G-test and GM-test were performed in few cases and in vitro susceptibility test was fewer.Only 2 strains of A.flavus were resistant to AMB and 2 strains of A.fumigatus were resistant to multidrugs.Itraconazole pretended to be the first choice for invasive aspergillosis.Corticosteroid alone or combined with itraconazole was applied to allergic bronchopulmonary aspergillosis.Surgical excision was recommended for chronic,saprophytic,nasal and paranasal sinus aspergillosis.Conclusions Trend of aspergillosis in mainland China was in concordance with the world.Mobidity of non-fumigatus aspergillosis increased,especially pulmonary involvements.Morphological and molecular biological identification are important for accurate and prompt diagnosis.In vitro susceptibility test is helpful for clinical treatment.
Coral Calcium: Fact and Conjecture

Substantial interest among both consumers and scientists surrounds coral calcium (1), but much confusion prevails about the characteristics and clinical outcome of the use of this dietary supplement. Emerging brands of coral calcium trumpet their own advantages while arguments prevail about which is the best type of coral calcium material in established brands. Consumer choices of coral calcium supplements are complicated by the availability of more than 150 different, neophytic brands of coral calcium.
A Learning Design: Integrating Tracker in Level of Inquiry to Enhance Seven Grade Student Science Process Skills and Graph Interpretation

Science process skills are important skills that need to be learned so that students can develop scientific concepts of science. However, the results show that science learning in the classroom has not been well facilitated, on the other hand the result of the research shows that the ability of graphic interpretation of SMP/MTs students is still low. Research using Level of Inquiry (LoI) and the use of tracker programs try to make it a solution. Pre experimental research with design one group pretest-posttest was implemented in 28 students obtained by purvosive sampling using instruments used to test students' graphic abilities is by test of Understanding Graph in Kinematics and to test the skill of science process students are by standard TIPS II test (Test of Integrated Process Skills II). The results of this study show that the <n-gain> of the graphic understanding is 0.53 in the average category, and <ngain> of the science process skills is 0.70 in the high category. The application of this learning strategy can significantly improve the skills of the science process and understanding of graphs and based on the results of research indicate that this instructional design can be an alternative in improving students' science process skills and graph interpretation in linear motion learning.
Effects of Exogenous Melatonin on Nitrogen Metabolism in Cucumber Seedlings under High Temperature Stress

Effects of exogenous melatonin(MT) on the nitrogen metabolism under high temperature stress were investigated in cucumber seedlings,including a heat-sensitive cultivar(‘Jinyou No.4’) and a heat-tolerant cultivar(‘American Baoer’). The results showed that under the stress of high temperature,the nitrate content in leaves of both cucumber cultivars increased firstly and then declined later.The total nitrogen or ammonium content in the leaves of ‘Jinyou No.4’ declined firstly but increased constantly in ‘American Baoer’. The activity of nitrate reductase(NR) increased firstly but then decreased later in the leaves of both cucumber cultivars,but the activities of glutamate synthase(GS),glutamine synthetase(GOGAT) and glutamate dehydrogenase(GDH) decreased continually.All of the four enzyme activities in ‘American Baoer’ decreased slower than those in ‘Jinyou No.4’. The exogenous MT could significantly increase the activities of NR,GS,GOGAT and GDH,increased the nitrate content and restrained the accumulation of ammonium content under high temperature stress.These results indicate that exogenous MT could enhance the nitrogen metabolism of cucumber,reduce the damage of high temperature to the plants,and improve the resistance of cucumber seedlings against high temperature stress.
Deep relightable textures

The increasing demand for 3D content in augmented and virtual reality has motivated the development of volumetric performance capture systemsnsuch as the Light Stage. Recent advances are pushing free viewpoint relightable videos of dynamic human performances closer to photorealistic quality. However, despite significant efforts, these sophisticated systems are limited by reconstruction and rendering algorithms which do not fully model complex 3D structures and higher order light transport effects such as global illumination and sub-surface scattering. In this paper, we propose a system that combines traditional geometric pipelines with a neural rendering scheme to generate photorealistic renderings of dynamic performances under desired viewpoint and lighting. Our system leverages deep neural networks that model the classical rendering process to learn implicit features that represent the view-dependent appearance of the subject independent of the geometry layout, allowing for generalization to unseen subject poses and even novel subject identity. Detailed experiments and comparisons demonstrate the efficacy and versatility of our method to generate high-quality results, significantly outperforming the existing state-of-the-art solutions.
Transfer RNA-derived small RNAs: potential applications as novel biomarkers for disease diagnosis and prognosis

Transfer RNA-derived small RNA (tsRNA)s are novel non-coding RNAs, expressed in a variety of tissues and organs. Two subtypes of tsRNAs have been reported: tRNA-derived stress-induced RNA (tiRNA)s and tRNA-derived fragment (tRF)s. tsRNAs have been reported to play essential roles and possess different biological functions in a variety of physiological activities. Recently, tsRNAs have been implicated in a large number of diseases, such as cancers (including breast cancer, ovarian cancer, lung cancer, prostate cancer, colorectal cancer, etc.), neurological disorders, viral infections, metabolic diseases and angiogenesis-related diseases. Although the biological functions of tsRNAs are still poorly understood, correlations between dysregulated tsRNA expression and disease development have been recently reported. Additionally, their capabilities as potential biomarkers for disease diagnosis and prognosis have been revealed in clinical studies. In this review, we summarize the current knowledge of tsRNAs, and discuss their potential clinical applications as biomarkers in different diseases. Although the regulation of tsRNAs is similar to miRNAs in regards to the related physiological and pathological processes, the higher stability and expression levels of tsRNAs place them as ideal biomarkers for the diagnosis and prognosis in cancer and other diseases. Therefore, it is worth to verify the possibility and reliability of these reported tsRNAs as potential biomarkers for clinical applications in disease diagnosis and prognosis.
Analysis Of Wellbore Image Data Applied To Environmental And Geotechnical Case Studies

The application of borehole televiewer (BHTV) data analyses recorded in the shallow crust to environmental and hydrological investigations is fourfold: 1) fracture characterization, 2) in-situ stress measurement, 3) providing site geologic and lithologic constraints, and 4) geotechnical monitoring. One of the primary uses of the borehole televiewer data since the tool became operational in geophysical logging has been measurement of the orientation and distribution of planar features in a drillhole. The resolution of the borehole televiewer is capable of detecting a wide range of fracture sizes and these data can provide a wealth of information pertinent to understanding the mechanical behavior of the Earths crust at a drillsite. Fractures provide permeable pathways for fluids and affect rock properties by chemical alteration of the surrounding rock mass. Fracture geometry is therefore important to fluid flow and permeability in reservoirs and waste disposal sites and to the safety of groundwater aquifers. In situ stresses play a major role in the stability of natural and man made structures. The measurement of stress orientation and magnitude, possible through the analysis of BHTV image data, can provide information about the ambient tectonic stresses and information crucial to the design, construction and monitoring of dams, tunnels or aqueducts. Stress orientation and magnitude also has a major impact on the development of natural fractures and subsequent movement along preexisting fault surfaces. In shallow crustal wells the constraints placed on in-situ stress from the analysis of BHTV data are important to interpreting the interaction between pore pressure and hydrostatic pressure in a well and subsequent wellbore stability. Case studies from wells that exemplify the application of BHTV data analysis to geotechnical and environmental issues are presented. The first study involved in the siting and construction of a major aqueduct/tunnel in central Utah. The objectives of this study were to characterize the natural fractures within the shallow crust at the drillsite and to determine the orientation of in-situ stresses. A second study, conducted in two phases, concerned the analysis of fractures developed in a concrete dam abutment in Colorado. Detailed measurements of the aperture of fractures detected by BHTV imaging were made at a ten month interval to help establish the integrity of the dam. Finally, a study of wellbore image data recorded at county landfill in Oregon was performed to measure the orientation, aperture and depth distribution of fractures at the site. The image data was used in conjunction with geophysical logs to discriminate between bedding plane fractures and through-going fractures in siltstone units and fractures in basalt units.
UCI-TR-2019-07 New Physics in b → s l + l − confronts new data on Lepton Universality

In light of the very recent updates on the RK and RK∗ measurements from the LHCb and Belle collaborations, we systematically explore here imprints of New Physics in b → sl+l− transitions using the language of effective field theories. We focus on effects that violate Lepton Flavour Universality both in the Weak Effective Theory and in the Standard Model Effective Field Theory. In the Weak Effective Theory we find a preference for scenarios with the simultaneous presence of two operators, a left-handed quark current with vector muon coupling and a right-handed quark current with axial muon coupling, irrespective of the treatment of hadronic uncertainties. In the Standard Model Effective Field Theory we select different scenarios according to the treatment of hadronic effects: while an aggressive estimate of hadronic uncertainties points to the simultaneous presence of two operators, one with left-handed quark and muon couplings and one with left-handed quark and right-handed muon couplings, a more conservative treatment of hadronic matrix elements leaves room for a broader set of scenarios, including the one involving only the purely left-handed operator with muon coupling. ar X iv :1 9 0 3 . 0 9 6 3 2 v 1 [h ep -p h ] 2 2 M ar 2 0 1 9

The positive rates of male and female were 5.81% and 7.28%,and there was no significant difference(P0.05). Conclusion The epidemic focus infective of A.cantonensis exists in Yunnan,and Ariophantidae sp.and A.fulica are important intermediate hosts of A.cantonensis,Rattus novegicus and Rattus flavipectus are nature final hosts.Guinea pigs and rabbits are not the proper final hosts of A.cantonensis. Rats can be an ideal model of experimental animal of A.cantonensis.
Clinical Study of Respiratory Distress Syndrome in Al-Kadhimiya Teaching Hospital

Background Respiratory distress syndrome (RDS) or hyaline membrane disease (HMD) is an acute lung disease of the newborn caused by surfactant deficiency. It is Seen primarily in neonates younger than 36-38 weeks of gestational age weighing less than 2500 gram. Objective To find out the incidence, main risk factors of HMD, note the changes in serum calcium, potassium and sodium and to study the outcome of HMD during the period of the illness. Methods A prospective study was performed on one hundred neonate admitted to the neonatal care unit in AlKadhimiya Teaching Hospital. Sex, gestational age, weight, mode of delivery, maternal illnesses were studied as risk factors. Serum calcium, Na and K were measured. Results The incidence of RDS was 0.75% of total live births, 98(98%) of them were below 2.499 kilograms and less than 37 weeks of gestational age. Risk factors of RDS are male sex accounted for 61% of total cases. Cesarean sections were 28% of the total. Maternal diabetes mellitus represented 25%. Perinatal asphyxia was 22%. Familial predisposition had an incidence of 8% and finally prolonged rupture of membranes stood for 5%. Hypocalcaemia and hypokalemia were common with serum sodium was within the lower normal limits. The time of improvement for most babies (about 40%) was by day 4 of life. Mortality was 30% with the major percentage of death (which was 90%) was between day 1 and day 4. Conclusion RDS occurs predominantly in premature babies as a main risk factor with male sex and cesarean sections. In addition to other risk factors such as maternal diabetes mellitus and perinatal asphyxia. Associated changes in serum electrolytes and serum calcium including hypocalcaemia, hypokalemia and lower normal serum sodium are common. The 4th day of life was the time of improvement for most babies while most of them who died did so by the first 4 days of life. Among the admitted babies, about third of them (actually 30%) died because of RDS.
Parental Leave and Women’s Return to Work in Korea

The paper examines the impact of the parental leave on women’s employment in Korea. The paper exploits the natural experiment of the extension of the effective parental leave from 12 months to 15 months. The preliminary results are as follows. First, with the job-protected leave extended, female employees indeed took up the leave more often and for a longer period than before. The impact is found to larger for those with lower income. Second, the rate of return to work did not change significantly after the extension and weak heterogeneous impact regarding income is observed. This suggests that the marginal extension of leave in the vicinity of one year does not lead to a negative consequence in terms of women’s career. Further, the increase in the take-up rate implies that there exists a fixed cost in switching between own and paid child care.
SOFTWARE SIMULATION OF CLARINET REED VIBRATIONS

Electric Circuit Analysis Programs, such as MicroCAP [1] are useful for simulating acoustical and mechanical behaviour of musical instruments. As has been shown in [2], frequency dependent characteristics such as acoustical impedances of wind instruments can be simulated. Also pressure and volume-flow inside a tube can be demonstrated graphically [3]. A so called AC-analysis was used for these tasks. In the present paper first the transient response of a purely mechanical device, the clarinet reed, is studied. MicroCAP offers the possibility to show several parameters on a time scale. For this a different analysis is used, namely TR-analysis (transient analysis). The quasi-static relation between volume flow and pressure difference is the only acoustical-mechanical question that is dealt with in this paper. The paper explains the electro-mechanical-acoustical analogies that are the basis for the simulations. Finally the suitability of the software-model used is demonstrated by checking the results against the literature [4], [5].
Aalborg Universitet Reviewing the challenges of port authority business model innovation

The port industry is in a state of flux and port authorities are increasingly expected to create new avenues of value creation and value capture by managing multiple business models. To explore the challenges accompanying this qualitative shift in competition for port authorities, this paper presents a systematic review of port research in which four business model development challenges are analyzed, including: 1. diversification of port customers, 2. requirements for new value creation, 3. changing possibilities and constraints of value capture and 4. network effects, clusters and strategic partnerships. Based on the four challenges, it is argued that business model innovation by port authorities requires changing the underlying business logic, the activities and resources and the configurational fit with other port actors’ business models. This proposition is based on a discussion on the interplay between the macro level port industry, the meso level rule structures within port systems and the micro level of port authority organizations.

Performance of crop sequences on coarse-textured soil under rainfed condition

An experiment was conducted during 1984-90 to study the performance of different crop sequences on coarse-textured soils of Hoshiarpur under rainfed condition. The crop sequences were greengram (Phaseolus radiatus L.). green-manure sunnhemp (Crotalaria juncea L.) and fallow during the rainy season, and wheat (Triticum aestivum L. emend. Fiori & Paol.), wheat + gram (Cicer arietinumL.)mixture and indian mustard [Brassica juncea (L.) Czernj. & Cosson] during the winter season. In the years of normal distribution of seasonal rainfall, sunnhemp-wheat or wheat + gram gave good yield. Under adequate seeding-zone moisture and well-distributed winter rain, green-manuring with sunnhemp-wheat sequence gave the maximulo yield. However, monetary retum of greengram-indian mustard was the maximum. Among the winter-season crops tried, indian mustard gave maximum economic return, greater stability of yield and less chance of crop failure due to severe drought.
Single differential νμ charged-current cross section with the MicroBooNE detector using the Cosmic

We perform a single differential νμ charged current (CC) inclusive cross section measurement in MicroBooNE using improved detector response simulation, reconstruction, and with improved cosmic ray-induced background rejection using an external Cosmic Ray Tagger (CRT). The measurement uses data recorded from Fermilab’s Booster Neutrino Beamline (BNB) between December 2017 and July 2018, corresponding to an integrated protons on target of 7.6e18). We present the results in a similar manner as our previous νμ charged current (CC) inclusive cross section to allow for direct comparison. The direct comparison highlights two improvements in this measurement over the previous measurement: firstly, the drastically reduced cosmic contamination achieved when using the CRT, and secondly the significantly improved detector modeling, with associated reduced systematic uncertainties. It is shown in this analysis that the outcome is an improved measurement (σ = 0.800± 0.030 (stat) ± 0.101 (sys) · 10−38 cm2) with much smaller uncertainties but a result consistent with that of the previous analysis (σprevious = 0.693± 0.010± 0.165 · 10−38 cm2).
