Active–Sterile Neutrino Oscillations in Neutrino-driven Winds: Implications for Nucleosynthesis
Authors: Xiong Zewei , Wu Meng-Ru , Qian Yong-Zhong
Published: July 2019

A protoneutron star produced in a core-collapse supernova (CCSN) drives a wind by its intense neutrino emission. We implement active–sterile neutrino oscillations in a steady-state model of this neutrino-driven wind to study their effects on the dynamics and nucleosynthesis of the wind in a self-consistent manner. Using vacuum mixing parameters indicated by some experiments for a sterile ν

s
of ∼1 eV in mass, we observe interesting features of oscillations due to various feedback. For the higher ν

s
mass values, we find that oscillations can reduce the mass-loss rate and the wind velocity by a factor of ∼1.6–2.7 and change the electron fraction critical to nucleosynthesis by a significant to large amount. In the most dramatic cases, oscillations shift nucleosynthesis from dominant production of 45Sc to that of 86Kr and 90Zr during the early epochs of the CCSN evolution.

We present deep near-infrared spectroscopy of six quasars at 6.1 ≤ z ≤ 6.7 with Very Large Telescope/X-Shooter and Gemini-N/GNIRS. Our objects, originally discovered through a wide-field optical survey with the Hyper Suprime-Cam (HSC) Subaru Strategic Program (HSC-SSP), have the lowest luminosities (−25.5 mag ≤ M
1450 ≤ −23.1 mag) of the z > 5.8 quasars with measured black hole (BH) masses. From single-epoch mass measurements based on Mg ii

⊙ supermassive black holes (SMBHs) accreting at sub-Eddington rates. The Eddington ratio distribution of the HSC quasars is inclined to lower accretion rates than those of Willott et al., who measured the BH masses for similarly faint z ∼ 6 quasars. This suggests that the global Eddington ratio distribution is wider than has previously been thought. The presence of M

⊙ SMBHs at z ∼ 6 cannot be explained with constant sub-Eddington accretion from stellar remnant seed BHs. Therefore, we may be witnessing the first buildup of the most massive BHs in the first billion years of the universe, the accretion activity of which is transforming from active growth to a quiescent phase. Measurements of a larger complete sample of z ≳ 6 low-luminosity quasars, as well as deeper observations with future facilities, will enable us to better understand the early SMBH growth in the reionization epoch.

Biogeography and Cophylogeny of Paussus favieri(Carabidae, Paussinae) and Pheidole pallidula(Hymenoptera, Myrmicinae)
Authors: Bergamaschi Davide , Moore Wendy , Di Giulio Andrea
Published: July 2019

The myrmecophilous carabid beetle, Paussus favieri, has a circum-Mediterranean distribution and it is completely dependent upon its host ant Pheidole pallidula during all stages of its life history. Using molecular sequence data we inferred the phylogenies of the populations of both the beetle and its ant host to determine if there are signs of co-evolution. A total of 34 P. favieri from France, Spain, Portugal, Morocco and Tunisia and 42 Ph. pallidula workers from the same countries, plus Greece and Italy, were collected and analyzed. Many mitochondrial and nuclear markers were sequenced, but only COI was evolving fast enough to infer the population-level phylogenies of the beetles and the ants. Preliminary analyses suggest that the European populations of P. favieri are derived from a single dispersal event from Africa, while several dispersal events are suggested for Ph. pallidula. We found the topologies of host and parasite trees to be generally congruent, as would be expected if the host and parasite have had a history of co-evolution or co-divergence.

Ice and Alpine Caves in Slovenia in Older Literature (17th to 19th Century)
Authors: Kranjc Andrej
Published: July 2019

Z današnjega slovenskega ozemlja je najstarejša literatura iz 16. stol. (opis Cerkniškega jezera, raziskave podzemeljskih vodnih zvez), toda alpske in ledene jame se v njej ne pojavijo pred 17. stol. Najpomembnejše in najbolj znano je Valvasorjevo delo “Die Ehre des Herzogthums Crain” (1689). Opisuje 3 jame iz Alp, a nobena ni prava jama. Izjema je izvir Savica, za katerega se je 250 let kasneje izkazalo, da je v resnici izvirna jama. Opisuje tudi nekaj ledenih jam in led v njih. Nekatere izmed teh je stoletje kasneje obiskal B. Hacquet, ki v delu “Oryctographia carniolica …” (1778 – 1789) jamski led razlaga pravilneje. Če upoštevamo Schmidlovo delo “Die Grotten und Höhlen von Adelsberg …” (1854), ki velja za prvo sodobno speleološko delo, lahko od srede 19. stol. dalje govorimo o pravi speleološki literaturi. V Gratzyjevem seznamu kranjskih jam s konca 19. stol. je omenjenih 7 alpskih jam in 30 ledenih jam. Zadnje so večinoma izven alpskega prostora, saj so tam ledene jame običajen pojav. Literatura, ki omenja alpske in ledene jame, je zelo različna, vmes so temeljna speleološka dela o ledenih jamah, kot sta Fuggerjevo »Eishöhlen und Windröhren” in Schwalbejevo “Über Eishöhlen”, pa tudi lokalna literatura, ki npr. poroča o pridobivanju ledu iz jam.The first printed literature mentioning caves in a nowadays Slovenia dates to the 16th century already (description of Cerkniško lake, research of underground water connections) but description of alpine and ice caves does not appear before the 17th century. The most important and the best known is Valvasorʼs work “Die Ehre des Herzogthums Crain” (1689). In the Alps he describes 3 caves, but none of them is a real cave. Exception is a spring of Savica which proved 250 years later to be really a spring cave. He described also some ice caves and ice formations in them. B. Hacquet visited some of the same caves a century later and in his work “Oryctographia carniolica …” (1778 – 1789) explained the formation of ice more realistically. In the middle of the 19th century appears a real speleological literature, as Schmidlʼs work “Die Grotten und Höhlen von Adelsberg …” (1854) is regarded as the fi rst “modern speleological work”. At the end of the 19th century the Gratzyʼs list of caves in Carniola (great part of the todayʼs Slovenia) includes 7 caves from the Alps and 30 ice caves. The last are practically all out of the high mountains, where the ice caves are a normal feature. The 19th century literature including alpine and ice caves is very diversifi ed, there are “classical” speleological works on ice caves as Fuggerʼs “Eishöhlen und Windröhren” or Schwalbeʼs “Über Eishöhlen”, and local literature or reports talking about extracting of ice for example.
Drinking Water Supply from Karst Water Resources (The Example of the Kras Plateau, SW Slovenia)
Authors: Ravbar Nataša
Published: July 2019

Na Krasu je bil od nekdaj največji problem oskrba s kakovostno pitno vodo, ki je omejevala poselitev in gospodarski razvoj območja. Sodobna oskrba ne zagotavlja zadostne količine pitne vode za gospodinjstva in gospodarstvo le na Krasu, temveč jo v poletnem času oddaja celo na Obalo. Oskrba s pitno vodo temelji na črpanju kraške podtalnice iz vrtin pri Klaričih in na dveh izvirih pod Nanosom. Pri snovanju vodne oskrbe kaže v prihodnosti vključiti številne lokalne vodne vire v povezavi s tradicionalno obliko vodne oskrbe. Pri tem ni izključena morebitna uporaba kapnice za potrebe namakanja vrtov, pranje avtomobilov, za komunalne dejavnosti (pranje ulic) in v kmetijstvu ter ponovna uporaba odpadnih voda za tehnološko vodo v industriji.In the past the biggest economic problem on the Kras plateau used to be drinking water supply, which has also been one of the reasons for sparsely populated Kras plateau.Today the Water Supply Company provides drinking water to households and industry on the Kras plateau and the quantity is suffi cient to supply the coastal region in the summer months as well. Water supply is founded on effective karst groundwater pumping near Klariči. Some water is captured from karst springs under Nanos Mountain as well.In water supply planning in future, numerous other local water resources linked to traditional ways of water supply need to be considered. Eventual rainwater usage for garden irrigation or car washing, for communal activity (street washing) or for the needs of farming and purifi ed wastewater usage for industry (as technological water) is not excluded.
The Origin of Sediments Inside Collapse Dolines of Postojna Karst (Slovenia)
Authors: Stepišnik Uroš
Published: July 2019

Na kraškem površju Slovenije najdemo več sto večjih udornic. Njihova dna lahko prekrivajo podorni bloki, melišča ali prst. Na ponornem obrobju krasa, kjer voda prenaša večje količine alohtonega materiala, so dna mnogih udornic zapolnjena z ilovnatimi sedimentnimi uravnavami. Podrobneje sem preučil 15 udornic v bližini Postojnskega jamskega sistema. Pokazalo se je, da so ilovnate sedimentne uravnave na istih nadmorskih višinah v večih sosednjih udornicah hkrati. Nivoji sedimentnih uravnav so primerljivi z višinami zapolnitev poplavne ilovice v bližnjih jamskih rovih. Proces sedimentacije in uravnavanja dnov udornic v nivoje je posledica poplav, ki so segale nad dna udornic in so povzročile sedimentacijo ilovnatega materiala in uravnavanje v njihovem dnu. Zato lahko na podlagi nadmorskih višin sedimenta v dneh udornic predvidevamo dinamiko sedimentacije v kraškem podzemlju, hkrati pa lahko na podlagi razvoja jamskega sistema ugotavljamo razvoj udornic.Several hundred collapse dolines are recorded on the Slovenian karst surface. Their fl oors are covered with boulders, scree or a soil layer. In ponor karst areas, where water transports signifi cant amount of allochtonous material, many collapse doline fl oors are made level by deposits of loamy sediment. This discussion relates to a detailed study of 15 collapse dolines near the Postojna cave system. Loamy sediment appears within several neighboring collapse dolines and covers their fl oors at approximately the same altitude. The sediment level preserved in the collapse dolines is commonly at the same elevation as fl ood loam deposits within nearby caves. It transpires that the fl attening of the collapse doline fl oors is a result of fl ooding inside the karst that extended above the original fl oors of the collapse dolines. It is possible to predict some of the sedimentation dynamics inside the karst on the basis of the elevations of the loamy sediments within the collapse dolines. On the other hand, it is also possible to fi nd out about collapse doline development by studying the processes inside cave systems.
Nenavadna poškodba na losovi čeljustnici iz Franc-losovega brezna nad Glažuto pri Ribnici
Authors: Jamnik Pavel
Published: July 2019

Obravnavana je neobičajna poškodba z zaobljenimi robovi na spodnji čeljustnici Evropskega losa, katerega skeletne ostanke so jamarji našli v breznu nad Glažuto. Poškodba se razlikuje od naravno nastalih poškodb kosti, ki nastajajo v jamah in sedimentih. Mali sesalci pri grizenju kosti puščajo drugačne sledi. Morda so poškodbe povzročili polži? Domneva o tem, da polži poškodujejo fosilne kosti, je bila prvič predstavljena na primeru obravnave lukenj v fosilnih nosorogovih kosteh iz Dolarjeve jame pri Logatcu. The article deals with unusual bone damage with rounded edges, found on the lower jawbone of a European moose. The remains of its skeleton were discovered by speleologists in the shaft above Glažuta. This damage differs from those, caused by nature in caves and sediments. Small mammals leave different tooth marks when gnawing bones. Maybe the damage was caused by snails? The assumption that snails damage fossil bones was first presented in case of the holes in fossilized Rhinoceros bones from Dolarjeva jama at Logatec.
An Introduction to Some Cave Fauna of Malaysia and Thailand

V jamah tropske jugovzhodne Azije pogosto prebivajo zelo različni predstavniki jamske favne, od mikroskopskih nevretenčarjev do kač in netopirjev na vrhu prehranjevalne verige. Ta prehranjevalna veriga je odvisna od netopirjev. Večji sesalci, kot so ježevci, koze in sloni tudi občasno iščejo v jamah zatočišče ali hrano. Živali, kot so netopirji, so človeku koristne. Gnezda jamskih hudournikov, ki jih ljudje nabirajo, dosegajo na trgu visoko ceno. S preučevanjem jamskega živalstva so se v Maleziji in na Tajskem pričeli ukvarjati konec 19. stoletja.Tropical caves of southeast Asia are often home to a wide range of cave fauna, ranging from microscopic invertebrates through to snakes and bats at the top of the food chain.. This food chain is dependant on the bats. Larger mammals, such as porcupine, goats and elephants may visit caves for shelter or food. Animals such as bats are useful to man, whilst the nests of cave swiftlets are harvested and fetch high prices on the market. Studies on cave fauna began at the end of the 19th century in Malaysia and Thailand.

Published: July 2019

The composition, thermal stability and phase behavior of tamarind (Tamarindus indica) seed oil were analyzed to contribute to the exploration of their potential uses. The oil was extracted from the kernel of the tamarind seed with hexane, and its main physical, chemical and thermal properties were analyzed by infrared spectrometry, gas chromatography-mass spectrometry, DSC, and TGA. The results showed that the tamarind seed had a 3.76 ± 0.20% oil with a saponification index of 174.80 ± 9.87 mg KOH/g and the major fatty acids were lignoceric (20.15%), oleic (18.99%) and palmitic (11.99%). Stearic, behenic, linoleic, arachidic, and other fatty acids were also present. TGA and DSC showed that in an inert atmosphere, the triacylglycerols of tamarind seed oil (TSO) are decomposed in a single stage that starts at 224.1 °C and in an air atmosphere in three stages, initiating its decomposition at 218 °C. The TSO showed crystallization and fusion curves with a single maximum peak with Tonset and Toffset of 20.16 and ?38.8 °C and ?22.2 and 28.6 °C, respectively. The solid fat profile of the oil showed a semi-solid and liquid consistency in the ambient temperature range. The composition, thermal and phase behavior showed that TSO is potentially useful for alimentary, pharmacological, and cosmetological purposes.

Published: July 2019

In recent years, environments of bearings and polymer materials have been more and more attractive due to several advantages against ordinary metal material. However, there is still room for the further study about strength of polymer bearings. One of questions is the mechanism of fatigue crack propagation, which is the main cause of the damage of polymer bearings under rolling contact with lubricant, like water. In this study, subsurface stress distribution and failure of PPS thrust bearings under rolling contact fatigue in water are discussed to understand the detail of the crack propagation.
Fundamental Research on Gasification Dephosphorization with Coke Powder Reducing Converter Molten Slag
Authors: Li Chen Xiao , Xue Yue Kai , Wang Shu Huan
Published: July 2019

In order to realize the gasification dephosphorization process in converter slag splashing stage for avoiding the P enrichment, and the dephosphorized slag can be left for recycling in subsequent furnaces. The experiment of reduction of converter slag by coke powder in laboratory was carried out, The results show that with the increase of the experimental temperature, the gasification dephosphorization rate of coke powder gradually increases, and the gasification dephosphorization rate reaches up to 82.35% at 1900K. The gasification dephosphorization rate decreases with the increase of slag basicity. When the coke powder is added in a sufficient amount, increasing properly the FeO content of slag is favorable for the gasification dephosphorization reaction; when the coke particle size is between 0.5 and 2.5 mm, the gasification dephosphorization rate changed little, about 58%, but when the coke particle size between 2.5 and 3.5mm, the gasification dephosphorization rate dropped to 52%. The results provide some theoretical guidance for industrial development.
Experiments and Regression Analysis of Grinding Hardened Layer Depth Based on Transverse Feed
Authors: Gao Shun Xing , Liu Ju Dong , Xu Zhi Long , Yang Xiao Fan
Published: July 2019

Based on orthogonal experiments, the influences of grinding process parameters including depth of cut (ap), workpiece infeed velocity (vw) and transverse regrinding value (Cr) on hardened layer depth (HLD) of 40Cr steel are studied in the grind-hardening process. The grind-hardening orthogonal experiments of 3-factors are performed on the 40Cr steel with the L16 (45) orthogonal table and the experimental optimization design theory. To understand quantitatively the effects of three grinding process parameters, the experimental data are modeled by regression. Among three grinding process parameters, the most important parameter is ap, followed by vw and Cr respectively. The experimental results indicate that HLD would increase with the increasing of the depth of cut and the decreasing of the workpiece infeed velocity in grind-hardening process, but HLD would decrease with the increasing of the interaction between the depth of cut and workpiece infeed velocity.

Published: July 2019

Aiming at the damage and failure problem of copper alloy netting structure, the ultimate strength and fatigue performance of the net structure were studied by test method. Based on the research on the ultimate strength of copper wire, through a series of fatigue tests on copper wire and net structure, the fatigue life and failure modes of copper wire and net structure under different loads are analyzed, and their fatigue life curves are also drawn. The results show that the fatigue strength of copper wire and net structure considering corner processing is lower than that of copper wire not considering corner processing, which indicates that corner processing has a great influence on the fatigue strength of actual copper net structure. Compared with the fatigue strength value of 32.8 MPa of the copper net, the fatigue strength value of the net structure decreases to a certain extent (about 14.3%), which indicates that the assembly process of the copper net has certain influence on the fatigue life of the net structure.

Authors: Sivanesan Sivakumar , Loong Teow Hsien , Namasivayam Satesh , Fouladi Mohammad Hosseini
Published: July 2019

Addition of CeO2 into ZTA and its effects on microstructure and mechanical properties were investigated. CeO2 was detected with significant amounts only above 10 wt%. Viscosity was measured for slurry preparartions and characterization of mechanical properties of ZTA. Additions of CeO2 of more than 10 wt% surpassed the solubility limit and formed Ce2Zr3O10. Ce2Zr3O10 increased the tetragonality factor, prevented excessive grain growth through a pinning effect, which is attributed to the segregation of Ce2Zr3O10 to the grain boundaries and showed a peak in fracture toughness with a value of 9.3 MPam1/2 with 10 wt% additions of CeO2. Further additions of CeO2 reduced ZTA’s mechanical strength. Maximum value of Hv was 17700 MPa with 10 wt% CeO2. Porosities have been attributed as the underlying reason as to why theoretical density were always higher than measured densities.
A Model for Bond Strength in Presence of Corrosion in Concrete
Authors: Cesetti Alessandro , Savino Pierclaudio , Tondolo Francesco
Published: July 2019

Corrosion of steel in concrete is the most detrimental source for reinforced concrete structures. Among the other effects, corrosion deteriorates the interface between steel and concrete. An axisyimmetric numerical model able to simulate the structural behaviour of bond between steel and concrete is here presented. The model is based on the thick-walled cylinder theory so that bond performance is a direct consequence of radial pressure acting on the rebar and coming from the surrounding elements and corrosion. Both elastic and inelastic contribution of concrete is also taken into account. The model is used to simulate pull-out tests present in literature. The results show the effectiveness of the model and is also compared with an empirical model already proposed in literature.

Published: July 2019

Microfluidic chip injection photocuring is a new method for microfluidic chip fabrication. The accuracy of microfluidic chip photocuring has an important impact on the reliability of microfluidic chip. The reaction rate of photocuring system directly affects the final quality and efficiency of microfluidic chip. The rapid reaction rate of photocuring system will lead to poor feeding effect of the reaction system. The forming accuracy is affected, and the reaction rate is too slow, which will increase the forming time and affect the forming efficiency. In this paper, the conversion rate and reaction rate of different active monomers and oligomers used in the formulation system of microfluidic chips were measured on-line. The photocuring reaction kinetics of microfluidic chips was studied, and the influence of the formulation system on the photocuring reaction was explored, which laid a foundation for optimizing the formulation of microfluidic chips.
Toughened Poly(Trimethylene Terephthalate) by Melt Compounding with Functionalized Graphene Oxide Nanocomposites
Authors: Wang Kun Yan
Published: July 2019

Functionalized graphene oxide (fGO) nanoplates were added to the Poly (trimethylene terephthalate) (PTT) matrix by melt mixing. The mechanical property and deformation mechanism of PTT/fGO nanocomposites were studied. Addition of a small amount of fGO in PTT improves remarkably tensile properties. The elongation break of PTT/fGO increased with addition of fGO in PTT matrix owing to preferential interaction between groups of fGO and PTT matrix.. The fracture mechanism is identified by scanning electron microscopic (SEM) ananlysis of the fracture surfaces. FGO in PTT/fGO nanocomposites were homogenously dispersed in PTT matrix, indicating that the function of fGO improve the compatibility between PTT and fGO.
Controlled Hydrothermal Synthesis of K2Ti6O13 Nanowires and their Photo-Electronic Response
Authors: Chen Yu Xiong , Ji Mu Wei , Wang Jin
Published: July 2019

A hydrothermal method using tetrabutyl titanate and KOH as reactants for synthesis of K2Ti6O13 nanowires was developed, obtaining nanowires with a uniform diameter around 10nm. It is shown that the hydrothermal temperature and the KOH concentration have little influence in tuning the growth of K2Ti6O13 nanowires. By changing the time for hydrothermal reaction, the length of K2Ti6O13 nanowires can be controlled from several dozen of nanometers to several hundreds of nanometers. The as-prepared K2Ti6O13 nanowires exhibit a wide and strong absorption band in the ultraviolet range (around 200~300 nm), and stable photocurrent of 0.5μA/cm2, which might suggest potential applications in solar cell and water splitting.

Receptor-interacting protein kinase 1 (RIPK1) regulates cell fate and proinflammatory signaling downstream of multiple innate immune pathways, including those initiated by TNF-α, TLR ligands, and IFNs. Genetic ablation of Ripk1 results in perinatal lethality arising from both RIPK3-mediated necroptosis and FADD/caspase-8–driven apoptosis. IFNs are thought to contribute to the lethality of Ripk1-deficient mice by activating inopportune cell death during parturition, but how IFNs activate cell death in the absence of RIPK1 is not understood. In this study, we show that Z-form nucleic acid binding protein 1 (ZBP1; also known as DAI) drives IFN-stimulated cell death in settings of RIPK1 deficiency. IFN-activated Jak/STAT signaling induces robust expression of ZBP1, which complexes with RIPK3 in the absence of RIPK1 to trigger RIPK3-driven pathways of caspase-8–mediated apoptosis and MLKL-driven necroptosis. In vivo, deletion of either Zbp1 or core IFN signaling components prolong viability of Ripk1−/− mice for up to 3 mo beyond parturition. Together, these studies implicate ZBP1 as the dominant activator of IFN-driven RIPK3 activation and perinatal lethality in the absence of RIPK1.

Authors: Park Okhee , Kwon Insoo , Kang Youngsil
Published: July 2019

The purposes of this descriptive study were to identify the prevalence rate of urinary incontinence(UI) and the differences in frequency of incontinent and normal women by general characteristics, obstetrical history, and the conditional events for urinary incontinence of the elderly women in a community. By the results of this study, it is intended to provide nursing practice guidelines for incontinent women. The research design of this study was a preliminary descriptive study. The 173 subjects were 55 years old and over, and resided in a small city area. Data were collected from June 20 to July 20, 2001, by an interview or a self-report with questionaire. The questionaire was composed of items of general characteristics, obstetrical characteristics, and conditions of UI by the modified Henderickon's Stress Incontinence Scale(1981).The results were summariezed as follows: 1. The UI prevalence rate of the sample was 64.2%. Of the incontinent women, 31.5% had experienced UI for a period of three to five years, and 84.7% had never treated or managed their UI. Frequency of UI was once or twice times per month(46.8%).2. The total mean of UI on the scale in the incontinent women was 25.50 of 85, ranging from 18 to 41.3. The most frequent condition of UI was coughing, followed by laughing, sneezing, heavy exercise, and preparation of urination in descending order.4. There were significant differences in age, education, social activity, and urinary difficulty between the incontinent women and the normal women.5. There were significant differences in frequency of spontaneous abortion, age of menopause between the incontinent women and the normal women.6. There were no significant differences in number of delivery, frequency of artificial abortion, age of the last delivery, and postal health management between the incontinent women and the normal women. In conclusion, the incidence of UI in this study was high, but there were no effective treatments or management. It is suggested to provide the adult women with knowledge about UI, and to educate preventive behavior and control skill of urinary incontinence. Also episodes of urinary incontinence were high in the situation of sudden increase of abdominal pressure. This data can be used for the prevention strategy of urinary incontinence, In future research it is recommended to identify comprehensive factors related to urinary incontinence including psychosocial factors, and effective strategies of urinary incontinence.

This research is intended to study the dietary experiences by college women to promote women's health through the proper diet. The approach method was used grounded theory. The participants were selected 3 colleges in Seoul. Inchon, and Cheongju. The selected 15 women were college students who had a history of dietary experiences or who were on the way of diet at the time of the start of his research. The data were collected from August 2001 to October 2001. Data collecting method was a Focus Group Interview. The data were analyzed by the Strauss and Corbin's method(1996). The results were showed that the 236 concepts in the dietary experiences were gathered into 48 sub-categories, eventually being integrated into 17 higher categories. 'Esthetic self-pursuit' is the core phenomenon of the dietary experiences. Such Phenomenon is due to subjects physical problems, sense of comparison and desire of weight-loss. In the circumstantial context, the esthetic self-pursuit phenomenon is enhanced by social opinions, aesthetic senses and the recognition of self-control. The interaction strategy of the esthetic self-pursuit can be intensified and sustained by will power, supporting systems, and accessibility. Through the dietary experiences, the body changed positive or negative figures. Following the sense of success or failure the diet are sustained on abandoned accordingly. therefore, for the application of dietary experience as a available behavior for promoting health, an intervention strategy should be created a collect organized diet program in a social level not a private level.

Published: July 2019

Context

Anatomic differences of the knee in first-time patellar dislocators have not been clearly elucidated.

Objective

To compare structural differences of the knee in those who have sustained an acute first-time patellar dislocation resulting in a medial patellofemoral ligament (MPFL) tear by sex and age (≤17 years old, ≥18 years old).

Design

Case series.

Setting

Retrospective magnetic resonance imaging analysis.

Patients or Other Participants

Thirty-five acute first-time patellar dislocators with an associated MPFL tear.

Main Outcome Measure(s)

Patellar height using 3 methods, patellar alignment using congruency angles, and trochlear morphology using the sulcus angle. We compared the means of these variables by sex and age. The intraclass correlation coefficient was then calculated to assess the agreement of the independent reviewers.

Results

A total of 21 left and 14 right knees were analyzed. The MPFL tear location did not differ by sex (P = .34) or age (P = .43). Patellar height did not differ as measured by the Caton-Deschamps ratio (P = .29 for sex, P = .49 for age), Insall-Salvati index (P = .15 for sex, P = .33 for age), or patellotrochlear index (P = .67 for sex, P = .49 for age). The congruence angle (P = .81 for sex, P = .06 for age) and trochlear morphology as measured by the sulcus angle (P = .64 for sex, P = .45 for age) were similar between groups.

Conclusions

Patellar height and trochlear morphology did not differ by sex or age among patients whose first-time patellar dislocations resulted in an MPFL tear. In addition, the location of the tear did not appear to vary by sex or age.
An analysis of fixed capital formation in South Africa since 1994
Authors: Chetty Sivan
Published: July 2019

Fixed capital formation (investment) is an important but generally volatile component of aggregate spending. It is important in that it adds to the productive capacity of an economy. It is value-adding in the sense that it contributes to the growth potential of an economy, but it tends to be volatile as it entails substantial capital commitments based on uncertain expectations. The article undertakes a comparative analysis of fixed capital expenditure, using 1994 as an important year in which South Africa entered a new political dispensation. The article will attempt to evaluate the extent to which fixed capital decisions responded to a changing economic and political environment in terms of expectations and uncertainty.
Corporate governance practices at higher education institutions in South Africa
Authors: Marx Ben
Published: July 2019

South Africa boasts a vibrant higher education sector, with more than a million students enrolled in its higher education institutions. These institutions constitute highly complex organisations, with many and varied stakeholders and with budgets running into hundreds of millions of rands. Sound management and strict adherence to corporate governance principles and practices are essential to the success of these institutions. This will include the establishment of a well-balanced, independent and diligent council, as well as properly constituted and effective sub-committees of council. Of these sub-committees, the audit and finance committees are sure to play a pivotal part in ensuring financial discipline and adherence to sound corporate governance principles and practices. The principal aim of this paper will be to focus on the basic governance-regulatory requirements of higher education institutions in South Africa, and to benchmark these requirements against the corporate governance principles and practices required by King II.
Debating the methodologies of accounting for financial and non-financial contracts
Authors: Coetsee Daniël
Published: July 2019

This article adds value to the accounting debate on the different methodologies of accounting for financial and non-financial contracts in the current and proposed new accounting pronouncements of the IASB. The paper demonstrates that significant differences exist between the recognition and measurements of non-financial contracts in terms of the traditional accrual basis of accounting and financial contracts in terms of the so-called contractual basis of accounting applied for financial instruments, even though the accounting for financial instruments is seen as an extension of the traditional accrual basis of accounting. The current IASB’s projects on liabilities, revenue recognition and the conceptual framework seem to eliminate certain differences between the two methodologies, but also raise new issues on the debate of the methodologies to account for financial and non-financial contracts.
The changing role of management accounting systems towards value creation
Authors: Gimžauskienė Edita , Valančienė Loreta
Published: July 2019

Value concepts with a multi-stakeholder approach in the management accounting field are the subject of recent interest. The most popular management accounting conceptions, namely, activity-based costing (management) and balanced scorecard, reveal how the changed management accounting role integrates a focus on three key stakeholder groups: employees, customers and shareholders. Built on previous management accounting studies, this article explores when the management accounting system ensures value creation. The relationship between value creation and the management accounting system were disclosed using the multistakeholder theoretical approach. Research methods adopted in this study are empirical survey and empirical field study. The implementation level of modern management accounting conceptions was analysed using quantitative data (survey). Deeper analysis was performed in a Lithuanian organisation disclosing relationships between value creation and the implementation level of management accounting conceptions (case study). The results of the research revealed that modern management accounting conceptions might be a precondition for the changing role of management accounting but it depends on the implementation level and the organisation’s ability to manage all capacities of these conceptions.
