A mild and facile way was used to prepare poly(nitriloethylenenitrilovinylene)-grafted multi-walled carbon nanotubes (MWCNTs-g-PNENV) nanocomposites via the "grafting to" method. The MWCNTs-g-PNENV nanocomposites are well dispersible in polar solvents such as water, tetrahydrofuran and ethanol. Chemical structure of the resulting product was characterized by Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM) and thermal gravimetric analysis (TGA). FTIR showed that the "grafting to" process belonged to covalent attachment mechanisms. TEM observations indicated that the MWCNTs were coated with a uniform PNENV layer, and the MWCNTs existed as a hard backbone. TGA data also showed that the PNENV shell was successfully grafted to the side wall of MWCNTs.


The Indonesian soccer is growing, it can be seen at the outbreak of the football schools. Gendut Doni Training Camp is one of the soccer school that is growing, but the lack of media to introduce the school. Therefore it is necessary to design the video profil as an identity that can represent the foot ball school. Multimedia is one form of visual communication that can provide information. Penilitian method used is cyclic strategy and systems development methods as a prototype, so expect a system designed according to the company's profile to be achieved by the football schools and to provide information to prospective students of the school football.


The identification of hydrocarbons buried on the seafloor is highly dependent on geophysical exploration capabilities. Seismic exploration has been an important tool in providing information on submarine stratigraphy before offshore drilling, but it is a challenge to identify the nature and saturation of the fluid in the structure by seismic exploration. Of all the physical properties, electrical parameters are the most sensitive to the fluids in the reservoir and would be able to be combined with seismic data to improve the identification of hydrocarbons at depth. However, the marine controlled-source electromagnetic method usually only considers the effect of electromagnetic induction and ignores the induced polarization (IP) effects. The IP effects can occur in the stratum where the reservoir is located due to a variety of factors, so considering the IP effects will make the modeling more reasonable and thus give more accurate results when interpreting and processing the data. We have used the integral equation method for modeling, adopted the scattering and superposition methods to calculate the dyadic Green's function required in the study, replaced the real resistivity with a complex resistivity that takes into account the IP effects, investigated the response patterns of different ion polarization models, and analyzed the influence patterns of various model parameters. These investigations will provide important contributions to the study of submarine hydrocarbon detection. The field data also show the amplitude, and phase response results of polarizability show that it gradually increases from the offset.


This paper presents temporal and spatial dynamics of urban expansion and its impact on the land use land cover (LULC) in Guwahati Metropolitan Area, India by using Geographical Information Systems (GIS) and Remote Sensing. The LULC changes were detected through the integration of remotely sensed Landsat imageries and GIS for the year 1991 and 2016. Normalized Difference Built-up Index (NDBI) was implemented for automated extraction of built-up areas and maximum Likelihood Supervised Classification and post-classification techniques were carried out to examine the LULC changes over a period of 25 years. The growth trend of built-up area and the LULC changes show that there are substantial exchanges of areas between vegetation and built up land along with dense forest loss occurring mainly in the hills and foothills in and around Guwahati mainly due to the need for coming up with a substantial increase in population and economic activities. The limited land availability and the confinement of forest areas to the hills have forced the utilization of higher grounds resulting in huge land use transformation from vegetated land and forests to built-up land.


Background The association of the use of sodium-glucose cotransporter 2 (SGLT2) inhibitor and incident dementia remains unclear. This study aimed to evaluate the risk of incident dementia with the use of SGLT2 inhibitor. Methods This is a population-based cohort study utilizing Taiwan's National Health Insurance Research Database. Each patient who took SGLT2 inhibitors was assigned to the SGLT2 inhibitor group, whereas 1:1 propensity score-matched randomly selected patients who were nonusers of SGLT2 inhibitors were assigned to the non-SGLT2 inhibitor group. The study outcome was incident dementia. Results A total of 976,972 patients newly diagnosed with type 2 diabetes mellitus (DM) between 2011 and 2018 were included in this study. After the patients' propensity score matching by age, sex, duration of DM, comorbidities and drug index date of the patients, a total of 103,247 patients in the SGLT2 inhibitor group and 103,247 in the non-SGLT2 inhibitor group were enrolled for analysis. The SGLT2 inhibitor group was associated with a lower risk of incident dementia (adjusted hazard ratio: 0.89, 95% confidence interval: 0.82–0.96; p = .0021). Diabetic complications were significantly lower in the SGLT2 inhibitor group compared with the non-SGLT2 group. Sensitivity analysis was also consistent with the main analysis. Conclusions Patients with type 2 DM who were prescribed SGLT2 inhibitors were associated with a lower risk of incident dementia compared with those not prescribed SGLT2 inhibitors in real-world practice.


There were deep depressions of the skin in the middle third of both 'thighs, extending downwards and inwards as furrows about six inches long. The depth of the indentations was between 34 and 3 inch. The affected skin was thin, relatively hard, wrinkled and darker than the surrounding normal skin. The patient did not complain 'of physical discomfort as a result of the local fat atrophy. Treatment consisted of injections of coconut oil under the atrophic skin. Coconut oil was chosen because it is semisolid at warm room temperature, is a safe edible fat, and boils and cools easily. After boiling, the liquid is allowed 'to cool to skin temperature or slightly above; 'this can be ascettained by testing with the hand the temperature of the syringe filled with the coconut oil. The range of safe temperature difference is quite wide, and the margin of safety is considerable. An injeotion of the liquified coconu't oil under 'the atrophic skin is carried out in the usual manner. The amount 'of oil injected will depend on the degree of the depression. In general, enough oil is injected in the various depressed 'areas 'to make them level with the 'adjacent skin. A 20-gauge needle is quite satisfadtory. After withdrawal of the needle, a collodion dressing is applied over the puncture made by the needle and allowed to remain for a day. The patient did not complain of discomfort immediately after the injection. However, within a day or two, a local reaction, m'anifesting itself 'as a slight discomfort and by redness and heat, ensued, but it did Canad. M. A. J. Nov. 19, 1960, vol. 83


The majority of human diseases are related with the dynamic interaction of many genes and their products as well as environmental constraints. Cancer (and breast cancer in particular) is a paradigmatic example of such complex behavior. Since gene regulation is a nonequilibrium process, the inference and analysis of such phenomena could be done following the tenets of non-equilibrium physics. The traditional programme in statistical mechanics consists in inferring the joint probability distribution for either microscopic states (equilibrium) or mesoscopic-states (non-equilibrium), given a model for the particle interactions (e.g. the potentials). An inverse problem in statistical mechanics, in the other hand, is based on considering a realization of the probability distribution of micro- or meso-states and used it to infer the interaction potentials between particles. This is the approach taken in what follows. We analyzed 261 whole-genome gene expression experiments in breast cancer patients, and by means of an information-theoretical analysis, we deconvolute the associated set of transcriptional interactions, i.e. we discover a set of fundamental biochemical reactions related to this pathology. By doing this, we showed how to apply the tools of non-linear statistical physics to generate hypothesis to be tested on clinical and biochemical settings in relation to cancer phenomenology.


Quantum dots (QDs) of nitride semiconductors have been studied intensively because of their usefulness for device applications. Recently, we have fabricated GaN dots by droplet epitaxy. The droplet epitaxy requires neither any anti-surfactants nor the induction of surface strain for the formation of dot structures, which means the possibility of the QD formation on any substrates. In this study, we investigated fabrication of InN dots by droplet epitaxy with changing substrate temperature. After nitridation of Si(111) substrates, 1 ML of In was deposited on the substrates at 200°C , leading to the formation of In droplets. Then, NH3 gas was irradiated on the In droplets for nitriding. AFM observation showed that the average density of dots of 1.1x10 cm at 450°C decreased as the temperature increased. Then, the density increased again up to 4.0x10 cm at 570°C. However, no InN dot was observed on the sample nitridated at 600 °C . In 3d X P S s p e c t r a i n Fig.1 indicates that In-N component was increased as the t empera tu re inc reased wh i l e In-O component w a s d e c r e a s e d . Almost all In atoms was found to bind to N atoms at 570°C by the formation of InN crystalline.


Brown dwarfs (hereafter BDs) are formed, like stars, by interstellar cloud collapse, but attaining masses of less then 0.075 M⊙ (Baraffe et al. 1998), i.e. too low core temperatures (< 3.5 × 106 K) to stabilize the nuclear burning of the hydrogen PP chain. Therefore, even the most massive BDs begin cooling after some 109 yrs. However, for masses above 0.06 M⊙, core temperatures become hotter than the lithium burning temperature (2.4 x 106 K). All BDs above 0.013 M⊙ (13 MJup) reach core temperatures above the 1.0 x 106 K necessary to burn deuterium from about 107 yrs. The IAU has adopted the definition of the planetary regime as objects having masses below the deuterium burning conditions. But BDs are likely to form well below this limit into the planetary mass regime down to some 5 MJup. It is therefore convenient, in the absence of indices on their formation mechanisms, to call them planetary mass objects or planemos.


Interferons (IFNs) are key regulators of a number of inflammatory conditions in which neutrophils play an important role in pathology, such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), where Type I IFNs are implicated in disease pathology. However, IFNs are usually generated in vivo together with other cytokines that also have immunoregulatory functions but such interactions are poorly-defined experimentally. We measured the effects of Type-I IFN (IFNα), elevated in both RA and SLE, on the functions of healthy neutrophils incubated in vitro in the absence and presence of pro-inflammatory cytokines typically elevated in inflammatory diseases (TNFα, GM-CSF). IFNα alone had no effect on neutrophil apoptosis, however it did abrogate the anti-apoptotic effect of GM-CSF (18h, p< 0.01). The enhanced stabilty of the anti-apoptotic protein Mcl-1 and delayed activation of caspase activation normally regulated by GM-CSF were blocked by IFNα: this effect was mediated, in part, by activation of p38 MAPK, increased turnover of the anti-apoptotic protein Mcl-1 and cleavage of caspases. IFNα alone also primed ROS production alone and maintained the transient priming effect of TNF for up to 4h: it also down-regulated GM-CSF and TNFα-activated expression of CXCL1, CXCL2, CXCL3, CXCL8, CCL3 and CCL4, but in contrast increased the expression of CXCL10. These novel data identify complex regulatory signalling networks in which Type I IFNs profoundly alter the response of neutrophils to inflammatory cytokines. This is likely to have important consequences in vivo and may explain the complexity and heterogeneity of inflammatory diseases such as RA, in which multiple cytokine cascades have been activated.


Different applications of nanostructures are related with fluid flows through these systems. In its turn, experiments show that flows in nanostructures have many specific features, which can't be explained in classical terms only. Particularly, flow through nanotube is extremely fast in comparison with the analogous classical one. We suggest a model based on the possibility of existence of molecular clusters (Frenkel crystallites) in the fluid. There are some experimental evidences of such phenomenon. Under this assumption one needs to take into account quantum effects. Particularly, the boundary condition, which plays the crucial role for the flow in nanostructures, takes the form of sliding condition instead of the adhesion condition for the classical flow. The parameters of the boundary conditions are determined by solving of quantum scattering problem for the particle of the fluid by the wall potential. Main features of the flow are described in the framework of the model. For very narrow nanotubes another phenomena have an influence on the flow- possibility of existence of solitons in nanotube walls. These soliton solutions are similar to Davidov's solitons in molecular chains. This model of flow is also described.


Orthogonal frequency division multiplexing (OFDM) is widely used in wireless communication systems, and it is a candidate for Cognitive Radios (CR). Shaping the spectrum of OFDM-based CR is needed to reduce the out-of-band radiations and reduce the interference delivered to the licensed user (LU). In this paper, shaping the spectrum using windowing and active cancellation carriers is discussed. It is shown that the use of windowing alone for large band is a better choice. The window choice in case of large number of subcarriers spanned by a LU is investigated and it is shown that the Hanning window outperforms the raised cosine window by 7dB. Computational complexity analysis is introduced and it shows a huge advantage by using windowing alone for large frequency bands and multiple bands vis-à-vis cancellation carriers. Simulations show that such technique offers no effect on the bit error rate performance.


What is TV? Or rather, what is the act of watching TV? Is TV still TV if you're watching it on your laptop or your iPhone? One thing for certain is that television, while still a media, is no longer a medium. Although the concept of Internet TV has been around for more than a decade, actual Internet TV is just starting to take shape. Now that more homes are being hooked up with broadband in the United States and connection speeds are getting faster, Americans are quickly changing how they watch TV and realizing that TV isn't what it used to be.


Objective To explore the risk factors in type Ⅱ diabetes with cerebral infarction.Methods A retrospective analysis was conducted in 487 patients with type Ⅱ diabetes in our hospital from January 2003 to June 2010.All the patients were divided into complication group(n=281)and non-complication group(n=206)according to the complication of cerebral infarction.The clinical and laboratory data of two groups were compared.Results Between complication group and non-complication group,there were statistically significant differences in age,diabetic duration,HbA1c,blood pressure,blood triglyceride,blood cholesterol,and insulin sensibility index.The result of logistic regression showed that age,HbA1c,hypertension and hyperlipidemia were related strongly to type Ⅱ diabetes complicated with cerebral infarction.Conclusion Age,HbA1c,hypertension and hyperlipidemia are the major risk factors in type Ⅱ diabetic patients with cerebral infarction.


An attempt was undertaken to evaluate the baking quality of winter triticale cultivars (Dagro, Bolero, Ugo, Malno, Tewo and the strain CZR 103/85) on the basis of identification and characteristics of HMW glutenin subunits. The composition of the glutenin fraction was defined by the method of electrophoresis SDS-PAGE. For electrophoresis of triticale glutenins the wheat cultivars Jubilatka, Eta, Neepawa and Henika were used as models since the composition of their glutenin subunits that are coded on chromosomes 1A, 1B and 1D is known. This made it possible to identify these subunits in the glutenin of the studied triticale cultivars. The studies showed apparent interdependences between glutenin subunits on the one hand and the values of parameters of pharinographic analysis and sedimentation test on the other. Despite this fact, defining the baking qualities on the basis of glutenin composition in the case of triticale is not so unambiguous as in wheats. The glutenin fraction of triticale cultivars may contain subunits that rarely occur and are not typical for wheats. High-molecular secalins coded by the loci of chromosome 1R occurring besides glutenins often overlap on the electrophoretic diagrams and additionally make the quality classification of the cultivars difficult.


Perceived responsiveness of a web page is one of the most important and least understood metrics of web page design, and is critical for attracting and maintaining a large audience. Web pages can be designed to meet performance SLAs early in the product lifecycle if there is a way to predict the apparent responsiveness of a particular page layout. Response time of a web page is largely influenced by page layout and various network characteristics. Since the network characteristics vary widely from country to country, accurately modeling and predicting the perceived responsiveness of a web page from the end user's perspective has traditionally proven very difficult. We propose a model for predicting end user web page response time based on web page, network, browser download and browser rendering characteristics. We start by understanding the key parameters that affect perceived response time. We then model each of these parameters individually using experimental tests and statistical techniques. Finally, we demonstrate the effectiveness of this model by conducting an experimental study with Yahoo! web pages in two countries and compare it with 3rd party measurement application.


The agricultural sector is the basis of livelihood for a large proportion of society in Ethiopia. In the three political regimes in modern Ethiopia, the Imperial, the military and the Ethiopian people revolutionary democratic front (EPRDF), agriculture has been regarded as a critical sector. The Agricultural Development Led Industrialization (ADLI) is the national policy of the country. Regardless of the government policy attention and investment, there is a long way to go for smallholders to ensure food self-sufficiency. Agriculture is the base of our food, transformation to industrialization, climatic change control system. Agriculture is the soul of our sovereignty for development as well as poverty reduction for individuals and country level. In Ethiopia, population density is high and has been increasing and agricultural land has been decreasing because of fragmenting or converting it into residential plots. To meet the domestic food requirements, use of improved production technologies developed by research is come out to be important. Therefore, the goal of this study was to analyze factors that affect the performance of agricultural products in Amahara region national state and to determine the highly significant input factors for producing high and qualified agricultural outputs. Data regarding total agricultural outputs and its input factors in study area of Amahara region from 2010 to 2018 was obtained from Amhara national state branch of the Ethiopian institute of agricultural sector. Correlation analyses were used to examine the strength of the relationship between each of the determinant factors with total agricultural output, while multiple regression analysis was employed to examine the simultaneous effects of several independent variables on the dependent variable, total agricultural outputs. These analyses were employed through the packages R and Stata to achieve the main objectives of the study. All of the independent variables were highly correlated with the total agricultural output. The overall regression model was highly significant (p-value < 0.01) with F = 45.532. The R-squared value implies that 93.8% percent of the changes in average total agricultural outputs are successfully explained by the variables used in the model of this study. If we take model size into account, 91.8% percent of the variation in average total agricultural output was explained by the values of the independent variables. Specifically, among the independent variables irrigated land, fertilizer, improved seed and pesticides are the most significant factors for total products (p-value < 0.05).


Modeling wave energy converters (WECs) to accurately predict their hydrodynamic behavior has been a challenge for the wave energy field. Often, this results in either low-fidelity, linear models that break down in energetic seas, or high-fidelity numerical models that are too computationally expensive for operational use. To bridge this gap, we propose the use of dynamic mode decomposition (DMD) as a purely data-driven technique that generates an accurate and computationally efficient model of an oscillating surge WEC (OSWEC). Our goal is to model and predict the behavior of the OSWEC in monochromatic and polychromatic seas without knowledge of the governing equations or incident wave field. We generate the data for the algorithm using a semi-analytical model and the open-source code WEC-Sim, then evaluate how well DMD can describe past dynamics and predict future state behavior. We consider realistic challenges including noisy sensor measurements, nonlinear WEC dynamics, and irregular wave forcing. In each of these cases, we generate accurate models for past and future OSWEC behavior using DMD, even with limited sensor measurements. These findings provide insight into the use of DMD on systems with limited time-resolved data and present a framework for applying similar analysis to lab- or field-scale experiments.


This thesis is studying on the Design and development of a biomechanical robotize IPC device to accomplish a therapeutic methodology for recovery of cardio-circulatory functions, which may be seriously impaired in paraplegic patients. This impairment is caused by the reduction of venous return, due to the missing muscular contraction in zones without innervations. Intermittent Pneumatic Compression (IPC) is a well-known technique, which can be used for several therapeutic treatments like sports recovery, lymphoedema drainage, and deep vein thrombosis prevention. An IPC device produces a definite massaging action on the limb by inflating and deflating a given number of bladders according to particular time laws. The designed IPC device in this thesis is proposed for the lower limb to recover the venous return and preventing the Deep Vein Thrombosis (DVT) in the patients. The experimental tests on the volunteer persons showed the significant improvements on the important parameters of the cardiovascular, like the stroke volume (SV), the cardiac output (CO), and the end diastolic volume of left ventricle (LVEDV). To understand the dynamic behaviour of the IPC device and to optimize its performances, the device is characterized based on the mechanical and physiological aspects and its mathematical model is simulated in Simulink-Matlab. The validation of the mathematical model is done by comparing results with the experimental one. In addition, to apply the desired pressure pattern on the limb, two control strategies based on the PID algorithm and regulating inflating time are implemented on the model. The results of the controlled model, shows about 60% improving in performances of the device as concerns the bladder pressure control. In this case the experimental test has been done and it verified the control results of the simulation


Zirconium oxide (ZrO 2 ) coatings for 632.8nm center wavelength were deposited on the Ag layer by electron beam evaporation, optical thickness of which varied in the range of 80—480nm. Surface roughness and scattering characteristics of ZrO 2 coatings with different thickness were investigated. It was found that with the gradually increase of the thickness, both roughness and total integrated scattering (TIS) of the samples decreased firstly and then increased. These results indicated that TIS of the samples mainly depended on the surface roughness. According to the uncorrelated surface roughness scattering model, scattering properties of the samples were analyzed theoretically. The calculated TIS values based on this model agreed well with that obtained by TIS measurements.

For an odd prime $p$ and an integer $w\ge 1$, polynomial quotients $q_{p,w}(u)$ are defined by $$ q_{p,w}(u)\equiv \frac{u^w-u^{wp}}{p} \bmod p ~~ \mathrm{with}~~ 0 \le q_{p,w}(u) \le p-1, ~~u\ge 0, $$ which are generalizations of Fermat quotients $q_{p,p-1}(u)$.
First, we estimate the number of elements $1\le u<N\le p$ for which $f(u)\equiv q_{p,w}(u) \bmod p$ for a given polynomial $f(x)$ over the finite field $\mathbb{F}_p$. In particular, for the case $f(x)=x$ we get bounds on the number of fixed points of polynomial quotients.
Second, before we study the problem of estimating the smallest number (called the Waring number) of summands needed to express each element of $\mathbb{F}_p$ as sum of values of polynomial quotients, we prove some lower bounds on the size of their value sets, and then we apply these lower bounds to prove some bounds on the Waring number using results from bounds on additive character sums and additive number theory.


Tissue elasticity is measured by shear wave elasticity imaging methods using acoustic radiation force to create the shear waves. Reliable tissue elasticity measurements are achieved with strong shear waves. Phase aberration and tissue attenuation can hamper the generation of shear waves for in vivo applications. In this study we explored how phase aberration and tissue attenuation affects ultrasound focusing for creating shear waves, the resulting phase screen, acoustic field, shear wave amplitude and the shear wave velocity were measured. A Verasonics ultrasound system equipped with a linear array transducer (L7-4), an excised piece of swine belly tissue consisted of the skin, subcutaneous fat, and muscle and an elastic phantom were used. The ultrasound frequency used to generate shear waves was varied. The acoustic pressure and shear wave amplitude decreased with the introduction of the tissue layers. Decreasing the ultrasound frequency was important for maintaining a focused beam for creation of shear waves in the presence of phase aberration and attenuation. Analysis of shear wave production with a tissue layer (aberration and attenuation case) and measured phase screen (only aberration case) showed that tissue attenuation affects the shear wave generation more than tissue aberration.


One essay was conducted under laboratory conditions, in order to verify the influence of substrate water content on the germination of onion (Allium cepa L.) seeds. The effect of five water levels in the medium soil x sand (3:1) - 20, 40, 60, 80 and 100% retention capacity-were evaluated through the emergence percentage 14 days after seedling and the weight of fresh and dry matters of normal seedlings. For that purpose, 200 treated seeds of Pira Ouro cultivar were sown 1.5 cm deep in four replications of 50, with a constant water content in the medium. The best results showed that the soil moisture levels suggested for the germination of onion seeds were 40% to 60% of the substrate retention capacity, once they provide better emergence, weight of the fresh and dry matters of seedlings.


A number of new acyl derivatives of cytosine and 3-methylcytosines are described. Acylation normally yields N 4 - monoacyl compounds which, in hot 80% acetic acid, yield large amounts of uracil derivatives. Exceptionally, benzoyl chloride can also yield a 1 : N 4 - dibenzoate from 3-methylcytosine and a tribenzoate from cytosine. Similarly, benzoylation of cytidine yields, according to conditions, either a tetrabenzoyl or pentabenzoyl derivative.


The aim of this study was to investigate the cultural representation of deficiency in the media speech built up by the Ministry of Education (MEC) in its Teacher's Web Portal, seeking to identify the stereotypes and possible existing essentialization throughout the production about disabled people. Our analysis was based on Foucault's perspective of archaeological discourse analysis, therefore, we nominated as file a set of documents ranging from lessons elaborated in the section Espaco da Aula (Classroom), publications in Jornal do Professor (Teacher's Journal), in which one can find articles related to disabilities, supported by education professionals and broadcasted in institutional videos, as well as music, magazine articles, comic books, youtube videos, children's literature, among others. The research has showed that despite being an attractive website, due to its many qualities, such as possibilities of intervention and a heterogeneous set of techniques used, the Web Portal, which is subsidized by the Ministry of Education, persists in the production of disability in a pejorative and stereotyped way. Thus, despite the fact that the MEC Teacher´s Web Portal offers the teachers a variety of methodologies, showing desirable procedures and recommending pedagogical practices which meet the educational goals proposed by the Brazilian State to the education of people with disabilities in an inclusive perspective, it may end up producing the opposite effect, noticing that much of what is proposed in this formative website is related to a concept of a regulatory and pathological education, which contradicts the basic assumptions of inclusive education.


Use of a square-wave potential program for time-dependent amperometric detection of analyte zones in capillary electrophoresis (CE) is described. Electrochemical detection for CE requires that the separation field be isolated from that of the electrochemical detection. This is generally done by physically separating the CE separation field from that of the detection. By applying a time variant potential program to the detection electrode, the detector current has a time dependence that can be used to help isolate the electrochemical detection current from that of the separation. When using a 20 μm inner-diameter capillary, we find that a square-wave potential program decreases the RMS baseline current from 4.5×10−10 A, found with a constant potential amperometric detection, to 1.1×10−10 A when using a square-wave potential program. With a 75 μm inner-diameter capillary, the improvement is even more dramatic, from 2.3×10−9 A with amperometric detection to 2.06×10−10 A when using a 1 Hz square-wave potential program. When not using the time-dependent detection with the 75 μm capillary, the analyte zones were beneath the S/N for the system and not detected. With the square-wave potential program and time-dependent detection, however, the analyte zones for an electrokinetic injection of 200 μM solution of 2,3-dihydroxybenzoic acid were observed with the 75 μm inner-diameter capillary. The improvement in the ability to discriminate the analytical signal from the background found experimentally is consistent with modeling studies.


The connexion between pellagra and maize consumption has occupied the interest of many workers for a number of years. It has been suggested that maize owes its pellagragenic property to an imbalance of amino-acids, tryptophan being especially low. This imbalance was said to increase the need for nicotinic acid (Krehl, Henderson, de la Huerga & Elvehjem, 1946; Krehl, 1949). The presence of a 'toxic' factor in maize has also been postulated (Woolley, 1946 ; Borrow, Fowden, Stedman, Waterlow & Webb, 1948). Though this postulate cannot be entirely disregarded, it has not received experimental support in recent years. It is the purpose of this paper to present further evidence for another factor that may contribute to the pellagragenic property of maize, namely the unavailability of the nicotinic acid present in the cereal in 'bound' form. The observation that 'an unknown substance is present in cereals, giving the CNBr-p-aminoacetophenone reaction and which is more strongly bound than free nicotinic acid and liberated only after hydrolysis with NaOH' (Kodicek, 1940) has been confirmed by a number of workers (see review by Kodicek, 195 I a) . This 'bound' form of nicotinic acid is only partly available to Lactobacillus arabinosus and Lactobacillus casei (Krehl & Strong, 1944; Kodicek & Pepper, 1948; Clegg, Kodicek & Mistry, 1952). Microbiological and chemical evidence indicates that almost all the nicotinic acid in cereals, such as maize, wheat, barley, rye and rice, is present in this alkali-labile, 'bound' form, that differs from the known nicotinoyl derivatives (see Kodicek, I 95 I a). This 'bound' form of nicotinic acid does not appear to serve as a source of the vitamin for the nicotinic acid-deficient rat (Chaudhuri & Kodicek, 1950a; Kodicek, 1951b), chick (Krehl, Elvehjem & Strong, 1944; Coates, Ford, Harrison, Kon, Shepheard & Wilby, 1952) and duck (Heuser & Scott, 1953). Experiments with pigs, in which a deficiency of nicotinic acid was produced on diets containing a large proportion of maize (Birch, Chick & Martin, 1937; Chick, Macrae, Martin & Martin, 1938a, b ; Braude, Kon & White, 1946) suggest, by implication, that the 'bound' form is equally unavailable to the pig. On the other hand, dogs seemed to utilize a charcoal adsorbate of a partly purified preparation from wheat bran (Krehl et al. 1944). There is no direct evidence about the availability to man of the 'bound' form. Holman (1954)


Many aspects of the inter‐annual variability of the Indian summer monsoon (ISM) remain unexplained. While boundary forcing like SST, snow cover and land surface processes are known to play significant roles, they cannot explain all of the inter‐annual variability of ISM. We identify and show that nature and organization of dynamics play a critical role in the intensity, and hence the variability of ISM. Investigation using a 55‐year dataset from NCEP at different scales and locations clearly shows a sharp contrast in organized convergence at a scale of 20° between excess and deficit monsoon years; the deficit monsoon years, including 2002, are marked by suppressed organized convergence. The general conclusions are valid even in presence of moist convergence, indicating that it is the efficient organization through convergence that plays a critical role in monsoon intensity. The results thus provide new insight into the dynamics and simulation of monsoon.


The buffer-cache replacement policy of the OS can have a significant impact on the performance of I/O-intensive applications. In this paper, we introduce a simple fingerprinting tool, Dust, which uncovers the replacement policy of the OS. Specifically, we are able to identify how initial access order, recency of access, frequency of access, and long-term history are used to determine which blocks are replaced from the buffer cache. We show that our fingerprinting tool can identify popular replacement policies described in the literature (e.g., FIFO, LRU, LFU, Clock, Random, Segmented FIFO, 2Q, and LRU-K) as well as those found in current systems (e.g., NetBSD, Linux, and Solaris). We demonstrate the usefulness of fingerprinting the cache replacement policy by modifying a web server to use this knowledge; specifically, the web server infers the contents of the OS file cache by modeling the replacement policy under the given set of page requests. We show that by first servicing those web pages that are believed to be resident in the OS buffer cache, we can improve both average response time and throughput.


The discovery that radioactively induced sublimation can drive a layer of frozen tritium to uniform thickness strongly influences the fabrication of targets for inertial confinement fusion (ICF) power reactors. Targets utilizing solid fuel layers, made uniform by this process and incorporating either a foam layer or a vapour barrier, offer clear fabrication advantages over previous, similar designs incorporating liquid fuel.


A mild and efficient method for the synthesis of 3-arylnaphtho[2,3-f]quinoline-1,2-dicarboxylate derivatives via Povarov reaction of aromatic aldehyde, anthracen-2-amine, and but-2-ynedioate is described using Yb(OTf)3 as catalyst. The features of this procedure are mild reaction conditions, good yields, and operational simplicity.


Usual procedures for the recording and analysis of analog data are summarized and a technique
for on-line correlation and spectrum analysis by means of a small digital computer with analog input
and graphic output capability is described. This technique was programmed in FORTRAN II for an
SDS 920, and special emphasis was placed on ease of use by providing a man/ machine dialogue. This program is most suited to the analysis of analog signals in the sub-audio range. It is an example of the use of small digital computers as generallaboratory instruments.


Brigitta Olubas. Shirley Hazzard: Literary Expatriate and Cosmopolitan Humanist. Amherst, New York: Cambria, 2012, 284 pp. $114.99The case of Shirley Hazzard-like that of Christina Stead, with whom she may be compared but from whom she also dramatically differs-tests the limits of 'nation' as a category that can claim, define or in any sense contain her fiction. Even though its trace recurs in the journeys of Hazzard's female protagonists, Australia is thoroughly supplanted by places elsewhere. Yet if the Miles Franklin Literary Award for The Great Fire (2004) is any indication, Australians still want to claim her, against the grain, as our own. And not without reason. In her masterpiece, The Transit of Venus (1980), for example, the harbour environs of Sydney, where 'girls put their smooth faces to gardenias, inhaling December for a lifetime' (Transit 37), provide a sensory undertow that pulls against geographic isolation and cultural marginality. Born in 1931, Hazzard lived for only the first fifteen years of her life in Sydney before moving with her family to Hong Kong, also travelling to and working, for various interludes, in cities around the globe-in Wellington, London, Naples and New York. So it is hardly surprising that Australia, in her writing, seems caught in the aspic of mid-century provincialism. Her own passage through life took her to the great cities of the world, into the heart of global politics of which she was an acute observer. From 1953 she was employed in a clerical role at the United Nations, and in 1963, met her future husband, esteemed translator and biographer Frances Steegmuller, forming a very influential literary couple. New York has been her main city of residence since 1951. Living there still, she is held in high esteem, as most recently seen in a reception held in her honour at the New York Society Library, at which this sympathetic yet incisive study by Brigitta Olubas was also launched.Given Hazzard's international reputation, not to mention the emotional charge, ethical demand and sheer artistry of her fiction, it is hard to believe that Olubas's book is the first full-length critical study of her writings ever published-in the field of Australian literature or anywhere else. Hazzard has not languished alone, of course. There is much work still to be undertaken on many other writers of significance for Australian literature, and Cambria Press's Australian Literature Series (edited by Susan Lever) here continues to play a key role. Another reason for this extraordinary gap in Hazzard's case is suggested by Olubas's carefully considered subtitle. The rubrics of 'literary expatriate' and 'cosmopolitan humanist' cohere with the merest outline, given above, of Hazzard's biography; her 'cosmopolitan mobility' through the cities of the world. Without strong national orientation, at least in Australia, writers can be invisible in terms of the institutional underpinnings of local reception, arguably still a factor in the longevity and renewal of attention to literary work. Yet this may be exactly what makes Hazzard's work so timely for Australians now, given the porosity of national borders in the era of the internet and accelerated globalisation. Though transnational literary connections are not new, global circuits are increasingly embedded in daily life. This is also evident in the global, rather than cultural nationalist, orientation of much recent writing by Australians. Olubas's account is informed by this contemporary perspective, but understands Hazzard's writing in terms of twentieth century's changing global dynamics, highlighting her fiction's engagement with McCarthyist and Cold War eras, and-in The Great Fire-with the reconfigured global system within which Anglo-American cultural coordinates have increasingly been decentred. Hazzard's 'literary expatriate' career therefore illuminates the trajectory that leads to the present moment in which we find ourselves.A complex web of historical and geopolitical tensions, expressed in the conjunction of 'cosmopolitanism' and 'humanism', stands at the heart of this analysis which presents us not only with the first full retrospective of Hazzard's career but also a series of exact and exacting readings highlighting the paradoxes that motivate her writings. …


Cancer is an abnormal manifestation, a pernicious excrescence of life. For its understanding we must call on all biologic sciences. One of the most salutary aspects of cancer research is tha t so many scholars in diverse disciplines are thinking about cancer, pursuing leads with their own technics, and arriving at generalizations often contradictory to those of their peers. So arise one-sided theories: cancer is a virus disease, or an abnormal differentiation, or a somatic mutation, or an immunologic disorder, or a self-perpetuating defect in oxidative metabolism, or an adaptive deletion of a cell component. Any of these theories may appear overwhelmingly true within the horizon of one discipline. But they appear faulty on many scores when considered by scholars of other disciplines as the universal basis of the many diseases named cancer. On the other hand, such theories do elucidate some features of some cancers and thus need not be discourage& Who can claim the wisdom to comprehend fully all disc!plines? I am ever more convinced that, al though human brilliance can be multi-sided, it is more often not and that , outside

The present research study was conducted to explore the relationship between work motivation and organizational commitment in the banking sector of Pakistan. It was hypothesized that there will be a positive relationship between work motivation and organizational commitment. It was also hypothesized that there will be a positive relationship between work motivation and affective commitment, work motivation and continuance commitment and work motivation and normative commitment. Survey research design was used to conduct the study. Work Motivation Questionnaire by K G Agarwal was employed in the study for measuring work motivation of bank employees. The questionnaire was comprised of 18-questions. Organizational Commitment Scale by Allen and Meyers (1996) was used in the study for measuring organizational commitment of bank employees. There were 23-questions. Purposive sampling technique was used. Sample size consisted of 355 employees from different banks of Lahore. Mann-Whitney test, Kruskal-Wallis test, Pearson correlation and regression was used to analyze the data. The findings suggested that there is a strong positive relationship (r = 0.774**, p<0.005) between work motivation and organizational commitment. Implications of the study along with limitations and suggestions of the study are being discussed.

Abstract Rock dragons are medium-sized agamid lizards restricted to arid or semiarid rocky habitats in southern Australia. When eggs from two species (Ctenophorus decresii and Ctenophorus ornatus) were incubated at constant temperatures in the laboratory, temperature affected incubation period, hatchling tail length, and sex determination. At the lowest incubation temperature (25 C), all hatchlings were female; the proportion of males increased at higher incubation temperatures. Rock dragons are fast growing and short-lived lizards; in the field they reproduce for only one or two seasons. Females lay multiple clutches of eggs from spring through to late summer which, in the climatically temperate part of Australia where these species occur, suggests that the date of hatching may be a good predictor of hatchling sex. Any sex differences in hatching date would, in turn, translate into sex differences in body size at the beginning of the next reproductive season. If the relationship between body size and reproductive success differs between the sexes in adult rock dragons, this would provide a plausible basis for the evolution of temperature-dependent sex determination in these species.


We report a training study that assesses whether teaching the pronunciation and meaning of spoken words improves Chinese children's subsequent attempts to learn to read the words. Teaching the pronunciations of words helps children to learn to read those same words, and teaching the pronunciations and meanings improves learning still further. These results provide evidence that both phonological and semantic knowledge are causal influences on learning to read words aloud in Chinese. It appears that learning to read words in Chinese may entail a greater reliance on mappings from orthography to semantics than learning to read words in alphabetic orthographies.

ABSTRACT. Given an affine surjection of polytopes : P ! Q, the Generalized Baues Problem asks whether the poset of all proper polyhedral subdivisions of Q which are induced by the map has the homotopy type of a sphere. We extend earlier work of the last two authors on subdivisions of cyclic polytopes to give an affirmative answer to the problem for the natural surjections between cyclic polytopes : C(n; d 0)! C(n; d) for all 1 d < d 0 < n.

The DOE Knowledge Base is a library of detailed information whose purpose is to support the United States National Data Center (USNDC) in its mission to monitor compliance with the Comprehensive Test Ban Treaty (CTBT). One of the important tasks which the USNDC must accomplish is to periodically perform detailed analysis of events of high interest, so-called "Special Events", to provide the national authority with information needed to make policy decisions. In this paper we investigate some possible uses of the Knowledge Base for Special Event Analysis (SEA), and make recommendations for improving Knowledge Base support for SEA. To analyze an event in detail, there are two basic types of data which must be used sensor-derived data (wave- forms, arrivals, events, etc.) and regiohalized contextual data (known sources, geological characteristics, etc.). Cur- rently there is no single package which can provide full access to both types of data, so for our study we use a separate package for each MatSeis, the Sandia Labs-developed MATLAB-based seismic analysis package, for wave- form data analysis, and ArcView, an ESRI product, for contextual data analysis. Both packages are well-suited to pro- totyping because they provide a rich set of currently available functionality and yet are also flexible and easily extensible, . Using these tools and Phase I Knowledge Base data sets, we show how the Knowledge Base can improve both the speed and the quality of SEA. Empirically-derived interpolated correction information can be accessed to improve both location estimates and associated error estimates. This information can in turn be used to identi~ any known nearby sources (e.g. mines, volcanos), which may then trigger specialized processing of the sensor data. Based on the location estimate, preferred magnitude formulas and discriminants can be retrieved, and any known blockages can be identified to prevent miscalculations. Relevant historic events can be identilled either by spatial proximity searches or through waveform correlation processing. The locations and waveforms of these events can then be made available for side-by-side comparison and processing. If synthetic modeling is thought to be warranted, a wide variety of rele- vant contextu~l information (e.g. crustal thickness and layering, seismic velocities, attenuation factors) can be retrieved and sent to the appropriate applications. Once formedj the synthetics can then be brought in for side-by-side comparison and fhrther processing. Based on our study, we make two general recommendations. First, proper inter-process communication between sensor data analysis software and contextual data analysis sofisvare should be developed. Second, some of the Knowl- edge Base data sets should be prioritized or winnowed to streamline comparison with observed quantities.

The article proposes a study on the financial and accounting implications of tangible assets depreciation. According to national accounting rules and IFRS, depreciation is the equivalent to irreversible impairment of assets. This amend character is given by correcting the fixed assets counting value to obtain the net counting value. The value of depreciation calculated by applying redemption quota to the counting value of the asset is included in operating expenses for the duration of its use until full recovery of input value and affects the outcome of the exercise.


The group generated by the Weierstrass points of a smooth curve in its Jacobian is an intrinsic invariant of the curve. We determine this group for all smooth quartics with eight hyperflexes or more. Since Weierstrass points are closely related to moduli spaces of curves, as an application, we get bounds on both the rank and the torsion part of this group for a generic quartic having a fixed number of hyperflexes in the moduli space M 3 of curves of genus 3.

This work consists of evaluating the tensile and compression static allowable stress of a hybrid (metal-composite) riveted joint. The analyzed joint is composed by two sheets of 2014 – T6 aluminium alloy and a T300/5208 Graphite/Epoxy quasi-isotropic laminate, which were joined by twelve Lockbolt Swaged Collar rivets titanium alloy Ti–6Al–4V annealed. The joint was analyzed through a computational model developed using the Finite Element Method (FEM), with the fasteners modelled through the Multi - Springs technique. This method was widely used to simulate the mechanical behaviour metal-metal and composite-composite parts of the joint. It is validated comparing its results with analytical results of metallic joints available in the literature. Through this model, both the allowable load and its distribution in the fasteners of the joint were determined. Since the evaluated joint is subjected to double shear and, therefore, has no eccentricities, the presence of secondary bending was not observed, the bearing and bypass loads were the most relevant in evaluating the allowable loads of the joint. The load distribution in the joint and its components' safety margin was determined, with the laminate being the limiting component of the allowable load.


A revision of the Jurassic aphid family Genaphididae revealed that the type genus Genaphis did not have the characteristics usually attributed to this family. This discovery led to a series of taxonomic decisions. The diagnosis of the family Genaphididae is emended. The genera Aphaorus, Juraphis and Pterotella are moved to the Juraphididae, fam.n. The new family is included in the superfamily Palaeoaphidoidea. Additionally, two new species, Juraphis karataviensis sp.n. and Pterotella shartegensis sp.n., are described. Phylogenetic relationships among the taxa of Juraphididae, the position of the family, and the distribution and palaeoecology of the taxa are discussed.


An experiment to determine the advantages of diozan, iso-butyl alcohol, tertiary butyl alcohol, and ethyl alcohol as dehydrants and chloroform, toluol, xylene, benzol, methyl benzoate, methyl salicylate, and acetone as clearers is described. Materials fixed in Bouin's fluid, Zenker formol, and 10% neutral formalin were dehydrated, embedded, sectioned, and stained. Bouin's fluid produces less hardening, shrinkage and distortion than the other fixatives employed. Slow dioxan is the best method of dehydration. All the picric acid need not be removed from tissues to be embedded in paraffin. Tissue blocks not more than 4 mm. thick may be dehydrated and impregnated with paraffin by slow dioxan in 13 hours, fast dioxan in 10 hours, iso-butyl alcohol and tertiary butyl alcohol in 14 hours, and ethyl alcohol-chloroform in 17 hours without incurring any distortion due to rapidity of dehydration and infiltration.

To the Editors: A lthough clozapine is standard pharmacotherapy in patients with treatmentresistant schizophrenia, 33% to 71% are nonresponders to clozapine. Clozapineresistant schizophrenia is defined as having Brief Psychotic Rating scale improvement of less than 20% despite a trial of 8 weeks or more and plasma levels greater than 350 μg/L, no period of good social/ occupational functioning for 5 years or more, Global Assessment Functioning of less than or equal to 40, Brief Psychotic Rating Scale total score of greater than or equal to 45, Clinical Global Impressions score of greater than or equal to 4, and a score of greater than or equal to 4 on 2 of 4 positive symptom items.We describe the first case report highlighting the effective switch from clozapine to aripiprazole, resulting in remission of co-occurring schizophrenia and severe alcohol use disorder.


BACKGROUND: Comorbidities are a source of worry in women with pelvic organ prolapse. With increasing age, incidence of other medical conditions tends to increase hence it is not surprising to find comorbidities in women with pelvic organ prolapse.OBJECTIVE: To document the comorbidities among women with pelvic organ prolapse.
METHODS: This retrospective study was conducted at the National Obstetric Fistula Centre, Abakaliki South-East Nigeria. This study involved the review of medical records of women with uterovaginal prolapse between June 2012 and May 2017. The data of 1168 women were available for review.
RESULTS: The mean age was 49.76 ± 13.57 years. Comorbidities occurred in 250 (21.4%) of the cases reviewed. The comorbidities commonly encountered were hypertension in 139 (11.9%), obesity in 56 (4.8%), peptic ulcer disease in 17 (1.5%) and diabetes mellitus in 16 (1.4%). Others were anaemia and human immunodeficiency virus infection. Sixty-three women (5.4%) experienced a delay in surgery as a result of these comorbidities.
CONCLUSION: The comorbidities encountered in this study were obesity, hypertension, diabetes, anaemia, peptic ulcer disease and human immunodeficiency virus infection. There is need to adequately manage these comorbid conditions so as to prevent adverse surgical outcome.


As a special geological phenomenon, detachment fault had been found in many petroliferous basins at home and abroad. By using drilling and regional geological data, this paper studies the genetic mechanism and geological significance of Mazhai detachment fault in Dongpu depression. The result is that, 3 basic conditions of slope, plastic rock and regional tectonic stress field were necessary for forming of detachment fault; oil accumulation was more abundant below the fault surface, and less abundant above. The discovery of Mazhai detachment fault not only enriched geological tectonic theory, but also gave a deeper understanding of petroleum geological rule in Dongpu depression.

During the last quarter of the 20th Century there has been a strong groundswell of feminist critique of the dominant discourses in Leisure Studies. In addition to groundbreaking texts from all parts of the globe (see for example Wimbush & Wbot, 1988;
Henderson et al, 1989; Green et al, 1990; Wearing, 1998; Thompson, 1999), major conferences have been held with a theme of feminist critique. The LSA conference in Leeds, UK in 1998 was run in conjunction with the Second International Women in Leisure Conference and had as its theme, 'The Big Ghetto: Gender, Sexuality and Leisure'. The Third International Women in Leisure Conference will take place in Fremantle, Australia, in 2001, in conjunction with the Australia/New Zealand Leisure Studies Association. A further indication of this groundswell was the granting of full Commission status the WLRA Tasskforce on Women in 1997.
These developments indicate that feminist theorisation of leisure issues has become part of the research repertoire of people working in the field. Thus whilst quantitative studies such as those of Bittman (1991) continue to demonstrate women's disadvantage in access to leisure time, more and more qualitative work has theorised this disadvantage in terms of gender power relationships. This shift from the mere description of disadvantage to the analysis of the relationships which underpin that disadvantage allows the feminist researcher to explore the complexities of dimensions of power such as age, ethnicity, class, sexuality and ability which intersect with gender. In some instances, it also allows research to become a vehicle
for social change.
In this paper, I will use my own research with older people to show how feminist theories are being used in the closing decade of the 20th century to problematise one aspect of Leisure Studies, namely the gendered nature of public and private space.


Atmospheric turbulence accounts for a significant percentage of weather-related aircraft incidents in Norway. A turbulence modelling project is run by SINTEF in cooperation with the Norwegian Meteorological Institute. A nested model system designed for forecasting atmospheric turbulence has been developed. From mid 2007 the system has been operated for seven airports in Norway. Met.no Report No.2 2008 presents the system and gives verification results for the last months of 2007. The present note presents verification results for the first four months of 2008 and includes similar measures and scores as in the previous report. The present type of note will be produced on a routine basis every forth month as a regular part of the ongoing project. It has been decided to do a special studies for Vaernes airport. The airport is chosen as the one of the seven for which there are available AMDAR reports from aircrafts on a regular basis. The models validated includes HIRLAM 10-km (10-km resolution), UM 4-km and UM 1-km (Unified Model, 4-km and 1-km horizontal resolution) and the SIMRA model (approximately 100m resolution). As already mentioned, verification results from the period 1. January to 30. April 2008 are presented.


The past two decade has witnessed a nuanced approach to addressing the institutional and normative responses to Africa's unending security challenges, particularly the African Union's mandate to create the African Standby Force (ASF). The growing infeasibility of operationalising the ASF has thus stimulated the conception of the South African initiated African Capacity for Immediate Response to Crises (ACIRC). This article places the establishment of ACIRC within the theoretical concept of flexible integration, specifically the 'multiple-speed' approach. This approach highlights the willingness of a group of member states to proceed with integrative measures at a much faster and deeper pace. The possibility of developing an AU framework that sets the operational parameters of this idea is at the core of this article.


Some retailers and other firms expecting to improve their operating performance have established Credit Card Banks (CCBs) as a revenue management tool to handle their proprietary credit card receivables, as well as those from Visa and MasterCard. The expected improvement in performance has to come primarily from increasing sales revenue with the retailers' own private-label credit cards, from interest income and from reducing the amount of credit card receivables and the cost of financing them. We test the differences in corporate performance, primarily measured by the Economic Value Added (EVA), and the efficiency of the accounts receivable management, between firms with and without CCBs. We find no significant improvement in their performance. In addition, we document that retailers with CCBs have longer average collection periods and relatively more receivables than those without CCBs, and that there is no difference in the revenue growth rate between the two groups of retailers.


It has been observed that, in pregnant women, intravenous pyelography is more successful than in non-pregnant women and this has proved true in cases in which the two iodine compounds, uroselectan and abrodil, have been used. The success of this method of visualization in pregnant women has been explained by the fact that the fetus makes pressure either on the iliopsoas muscle or on the ureters as they cross the brim of the pelvis, or just before they enter the bladder. This observation incited us to try to imitate fetal pressure. To produce the necessary effect we have to apply pressure either on the bladder or the ureters, as the fetus applies its pressure. In the German literature on this subject, we read that pressure is applied over the abdomen to compress the ureters. This, obviously, is difficult and at times impossible of accomplishment, especially in obese individuals. When we realized the faults of the abdominal pressure method, we began to work out a method of imitating fetal pressure in the mo...


Is it possible to think of the experience of beauty, or aesthetic experience, as an experience within and through which we may process, construct, revisit and problematize meanings? The objective outcome of beauty would thus take on subjective value with which to confer meaning on, and make sense of, our lives. On these and other conceptual grounds, this paper asks whether educating to beauty in museum settings (with reference to one project in particular) can offer a valid form of adult education when delivered via a cultural, self-learning and self-educational dispositive based on a narrative-autobiographical approach, in which a museum mediator who has been duly trained in self-narrative and self-reflective practices plays a key part in facilitating the learning experience. More specifically, it is proposed that educating adults to beauty may lead them to experience growth, for example by increasing their capacity for wonder or helping them to critically decentre, etc., in the encounter between their own perspective and that of others, including the museum mediator. The actors in this journey-process, that is to say, museum mediators and their interlocutors, who include both Italian and international visitors, enjoy the opportunity to experience both self-care and care for others, where care is defined as a taking on of responsibility. Finally, the author examines the equivalence between educating to beauty-educating to narrative-educating to cultural, critical, active and responsible citizenship: the last-mentioned dimension represents an increasingly urgent priority within the education and training practices targeted at adults in the contemporary era, in which territorial barriers are giving rise to a deep and complex state of crisis that may also contribute to a loss of meaning at both the individual and collective levels. The approach discussed here is situated within a broader educational-pedagogical framework and agenda that is "interioristic" and "introspect¬tive" as well as closely related to the perspective of "narrative pedagogy".

1. Tasan(茶山) had continuous interests in the Book of Odes[詩經]. He told his sons, repeatedly in letters for his sons, to write poems of four-character following the spirit of the Book of Odes. Actually he himself also wrote poems of four-character, even though they are not large in numbers. 2. Tasan construed `poong(風)` as a satire, which means "dropping a hint, not talking frankly, to make a person learn a lesson for himself." The object of dropping a hint was a king in the first place, and then `father and son`, `king and subject`, `husband and wife`, and `between-friends` in turns. In brief Tasan thought that the spirit of the Book of Odes was a kind of awakening of king to rule a country well, and then awakening of `father and son`, `king and subject`, `husband and wife`, and `between-friends` to have a moral duty as human-being. 3. Tasan concluded that the writer of Gookpoong(國風) in the Book of Odes was a wise man and a virtuous man. This opinion was opposed to that of Zhuzi(朱子) that Gookpoong was a collection of folk songs. A wise man and a virtuous man referred to a royal subject, a good son, a virtuous wife, and a faithful friend. In other words, Tasan thought that the Book of Odes was a collection of poems on human morality sung by a royal subject, a good son, a virtuous wife, and a faithful friend with a pure heart. 4. Though he layed stress on the Book of Odes, Tasan actually did not write so many poems of four-character, unique style in the Book of Odes. He wanted his sons not necessarily to write poems of four-character, but to write poems of realizing the spirit of the Book of Odes. Through emphasizing the poems of four-character, Tasan seemed to express his thought of the nature and effects of poems in a manifestative form by borrowing the authority of the Book of Odes.


Starting with the generally covariant Dirac equation we give equations showing that the spin of the Dirac particle couples directly with the background gravitational field. By restricting the metric to one describing a general 3‐space metric (no gravitation) we reduce the spin‐covariant Dirac equation to a two‐component theory. Finally, the general form for the Pauli–Schrodinger equation is derived for any 3‐space orthogonal curvilinear system of coordinates.


The chemical modification of titanium gypsum was made by calcium lignosulfonate, naphthalene and polycarboxylate superplasticizer. The effect of different superplasticizer on the physical properties of titanium gypsum was studied. The test results show that the standard consistency water, setting time and mechanical strength of titanium gypsum had changed to different extent with the three types of superplasticizer added. Naphthalene superplasticizer had best modification effect on titanium gypsum and its optimum content was 3%. When the naphthalene superplasticizer dosage was 3%, the 2h flexural strength and the 2h compressive strength of sample were 1.15MPa and 2.37MPa. The micro structure of titanium gypsum hydration products was analysed by SEM and the action mechanism of superplasticizer was analysed.


Enterprises are faced with the dual pressures of reducing costs and saving energy and reducing pollution; yet it is entirely possible that the cost and pollution at the same time are cut down through enterprises' technological innovation and management innovation. Based on this idea, the authors tried to integrate the methods of value stream and material flow, simultaneously identifying and monitoring costs and pollution problems. In the basis of in-depth study up on value stream and material flow, it had been confirmed that the integration of value stream mapping and material flow analysis is necessary and feasible, and the integrated framework of the both had been represented in this paper.

news and update ISSN 1948-6596 commentary Biogeography and complex traits: dispersal syndromes, in the sea How dispersal potential manifests as realized mi- gration (sensu Wright 1931) is a core question that links pattern and process in biogeography, ecology and evolution. It is a question that cannot be an- swered by knowing about dispersal alone; the an- swer requires understanding how traits of organ- isms influence dispersal potential, how abiotic and biotic environments filter dispersers, and how in- teractions between organisms and environments determine dispersal routes (e.g., Johnson and Black 1994, Siegel et al. 2003, Shanks 2009). A new paper by Luiz et al. (2013), investigating de- terminants of range size in reef fishes, emphasizes that understanding the relationship between dis- persal potential and migration also may require understanding the traits of non-dispersive phases. Luiz et al. (2013) report that the characteris- tics of generally non-dispersive adult phases cor- relate strongly with differences in range size, which historically have been considered the con- sequence of differences among dispersive larval phases (e.g., Lester et al. 2007). The significance of this initially counter-intuitive finding is that it greatly enriches recent discussion of dispersal that, after decades focusing on the influence of pelagic larval duration (PLD), has, as the authors put it, "yielded mixed results" (Luiz et al. 2013:16498) By analogy, consider how the state of knowledge about dispersal in terrestrial plants might look if we studied fruits alone and not other diverse aspects of dispersal syndromes, such as the animals involved (e.g., Beaudrot et al. 2013). Luiz et al. (2013:16500) find that the indi- vidual and combined effects of adult body size (independent effect [IE] = 36%), nocturnality (IE = 26%), and schooling behavior (IE = 16%) "are more important in determining the size of geographic ranges than larval dispersal potential" (IE = 13%; Table 1). They suggest that these adult character- istics provide key advantages in terms of in- creased establishment success by decreasing pre- dation risk and reducing Allee effects. The result and inference make sense (Figure 1). Population genetic theory has long recognized the bipartite— dispersal and establishment—nature of migration (e.g., Marshall et al. 2010). Similarly, without dis- persal and establishment, there can be no mean- ingful expansion in range size. The same suite of population theory, how- ever, also highlights a weakness in the inference that correlation with adult traits means the domi- nant effects are in "population establishment af- ter propagule arrival" (Luiz et al. 2013:16499); em- phasis added). For example, adult body size tends to correlate with fecundity and with longevity in many fishes (Beverton 1987, Winemiller and Rose 1992, Hixon et al. 2006:306, Juan-Jorda et al. 2013; see also Figure 1a–d). Thus, although the fecundity advantage of large-bodied species may sometimes be counteracted by greater abundance of small-bodied species, complex relationships between body size and abundance (White et al. 2007) mean that larger fish can be both more fe- cund and equally or more abundant than smaller fish (e.g., Munday and Jones 1998). Thus, the ad- vantage of body size may accrue via post-dispersal processes and/or via increased lifetime output of larvae. The total effect size of dispersal poten- tial—considering lifetime larval production, PLD, and Luiz and colleague's preferred dataset—is therefore greater than 13% and possibly as large as 49% (i.e., 13.3% + 36.0%; Table 1), which could turn their conclusion upside-down. Moreover, if a substantial effect of body size is mediated via lar- val production, their justification for excluding the high-PLD trans-Pacific fishes is limited and the to- tal effect size of dispersal could be as high as 62% (i.e., 24.8% + 37.6%; Table 1), though this would require that other correlated factors, such as young-of-year growth, contribute little. Conse- quently, despite the advances made by Luiz et al. (2013)—a dataset including ~3-5% of marine fishes, an alternative perspective, and application of mixed models—we remain uncertain about the relative importance of factors influencing migra- tion and range size in this dataset and across frontiers of biogeography 6.1, 2014 — © 2014 the authors; journal compilation © 2014 The International Biogeography Society


The results of the investigation show that the primary disturbances of the carbohydrate metabolism, namely – a moderate hyperglycemia as a result of chronic glucose overload led to the complex of proatherogenic disturbances which are typical for an insulin resistance. It was also established the close connection between the syndrome components which is realized through such main mechanisms as hypertriglyceridemia (HTE) systemic inflammation and oxidative stress. These data show the independent significance of hyperglycemia as a factor which initiates the progression of metabolic syndrome.


The physical mechanism for triggering the changing-look phenomenon in active galactic nuclei (AGNs) is still unclear. We explore this issue based on the multi-wavelength spectral and flux variations for a changing-look AGN Mrk 1018 with long-term observations in the X-ray, optical/ultraviolet(UV), and radio bands. Both the optical and the X-ray emission experience rapid decay in changing-look phase during 2010–2015, where a re-flare appears in the optical/UV and X-ray bands. We find a time lag of ∼ 20 days of optical/UV behind X-ray variations in type 1.9 phase. The 5 GHz radio flux decreases by∼ 20% in type 1.9 phase during 2016–2017. We find both X-ray photon index (Γ) and the optical-to-X-ray spectral index (αox ) are anti-correlated with the Eddington scaled 2–10 keVX-ray luminosity (LX/LEdd) in the type 1.9 phase. However, the type 1 phase deviates from these two anti-correlations, which suggests that the change of broad emission lines might be regulated by the evolution of accretion disk (e.g., disappearing of the inner cold disk in the type 1.9 phase).


The flexible heterocyclic thioether ligand bis(pyrimidin-2-ylsulfanyl)methane in the centrosymmetric title compound, [Cu2Cl2(C9H8N4S2)2]n, links Cu2Cl2 dimers into a chain. The chains are linked into a three-dimensional network through C—H⋯Cl hydrogen bonds. The CuI atom is in a slightly distorted tetrahedral coordination environment.


Logistic supply and materiel maneuverability play an important role in modern war.The use of a Palletized Loading System Vehicle(PLSV) could not only promote materiel maneuverability remarkably,but also improve the efficiency of the whole logistic supply system.With more wide use of PLVS,more and more requirements for PLVS come forth along,such as high reliability and adapting various environment conditions.According to these requirements,this paper introduced the design process of a new type of PLSV,carried out simulations and analysis in Ansys,and finally achieved an optimized model.


In "A Response to 'Critique of an Article on Machine Learning in the Detection of Accounting Fraud'" (Bao et al. 2021), the author group chose not to respond to the fundamental issue raised in the critique (Walker 2021), which was: What was the justification for relabeling identifier values used to identify fraud in their sample? The point is critical. A justified reason would mean that the model beats the prior literature by a handsome margin. Without a justified reason, the model fails to improve upon existing logit-based methodologies. The author group did not provide a reason, much less a justified reason. I asked the question directly to the authors prior to the publication of my critique. As I reported in my critique, the authors responded in that initial email inquiry by saying that the relabelings were necessary because a consecutive sample was needed for each fraud case (see Walker 2021, 66). Not only was this requirement undisclosed in their original paper published in the Journal of Accounting Research, but it also made no sense, which provided the motivation for my critique. This issue concerns something called serial fraud, and it was addressed in Section 3.3 in the authors' original publication. Apparently, this issue came up in the review process because the authors wrote, "We thank the anonymous referee for raising this point," in reference to this section (Bao et al. 2020, 212 n.10). What that section says is that, since frauds can span multiple years, it is possible that the same fraud case could exist both in the training set and the test set used in machine learning. In these instances, the model could learn from its own case and, therefore, overstate results. To address this concern, the authors specifically stated that they Discuss this article at Journaltalk: https://journaltalk.net/articles/6037


Abstract Nitrogen and water management are essential factors for achieving adequate crop growth and development in organic production systems. A three-year field study examined effects of different forms of organic N fertilizers applied at side-dress and with different irrigation application rates on leaf, stem, and floret yields, volumetric soil water content (P v), and crop water use efficiency (WUE) in organically-grown broccoli (Brassica oleracea L.) in two regions of California; Santa Cruz (UCSC farm) and Five Points (Harris farm). At preplant, 'compost only' treatment (CO) was applied at 140 kg·ha−1 of N with an additional 112 kg·ha−1 of N applied as side-dress in one of the following forms: (1) fish powder (FP); (2) Phytamin [bloodmeal and feathermeal mix (BF)]; (3) BF mixed with NaNO3 (SN), or (4) seabird guano (SG). Leaf, stem, and floret yields collected from the UCSC farm had a greater response to additional N from side-dressing treatments irrespective of the form than plants at the Harris farm in all years. The interaction of side-dress and irrigation treatment significantly influenced leaf, floret, and stem yields at both locations. A greater Pv was measured from the 0–15, 15–45, and 45–90 cm depths when treated at 150, 100, and 80% crop evapo-transpiration (ETc), respectively, on both farms. Soil samples collected from the 45–90 cm depth had the highest Pv levels at both locations. The Harris farm had higher levels of Pv than the UCSC farm at all depths. The greater WUE was achieved with 80 and 100% ETc at the UCSC farm and with 100% ETc at the Harris farm. Based on the results, it appears that a side-dress application of 112 kg·ha−1 of N in addition to 140 kg·ha−1 of N applied as compost at preplant, and irrigation at either 80 or 100% ETc on the UCSC farm, and at 100% ETc on the Harris farm achieves the highest level of WUE. Organic broccoli growers need to consider fertility status of the site, soil type, seasonal precipitation, and form of side-dress for achieving highest yields in a sustained manner.


Aims. Results of different polarimetric campaigns at Complejo Astronomico El Leoncito (Casleo), San Juan, Argentina are presented. The aim of these campaigns was to search for objects exhibiting anomalous polarimetric properties, similar to those shown by the Ld-class asteroid (234) Barbara, among members of the same or similar taxonomic classes. Methods. The data have been obtained with Torino and CASPROF polarimeters at the 2.15 m telescope. The Torino polarimeter is an instrument that allows simultaneous measurement of polarization in five different bands, and CASPROF polarimeter is a two-hole aperture polarimeter with rapid modulation. Results. The campaigns began in 2005, and we found four new asteroids with Barbara-like polarimetric properties: the L-class objects (172) Baucis, (236) Honoria and (980) Anacostia, and the K-class asteroid (679) Pax. The polarimetric properties of the phase-polarization curves of these objects may be produced by a mixture of high- and low-albedo particles in their regolith as a result of the fragmentation of a substrate that is spectrally analog to the CO3/CV3 chondrites.


The configuration process of the Uruguayan historiographical field was slow. It began to bedefined by the middle of XXth century when education and professionalization centers like theFaculty of Humanities and Sciences of the University of the Republic (1945) and the Institute ofProfessors Artigas (1949) were established. The backgrounds go back to the period ofmodernization and were articulated in a diffuse transnational space, of Rio de la Plata area,conditioned by the guidelines provided by an intense interaction among authors and currentswhich generated founding stories and identity mythemes of nationalist character. The objectivesof this article are to analyze its records, its consolidation process, and to identify its particularcharacteristics.

Aging-related salivary dysfunction commonly induces the poor oral health, including decreased saliva flow and dental caries. Although the clinical significance of the salivary glands is well-known, the complex metabolic pathways contributing to the aging-dysfunction process are only beginning to be uncovered. Here, we provide a comprehensive overview of the metabolic changes in aging-mediated salivary gland dysfunction as a key aspect of oral physiology. Several metabolic neuropeptides or hormones are involved in causing or contributing to salivary gland dysfunction, including hyposalivation and age-related diseases. Thus, aging-related metabolism holds promise for early diagnosis, increased choice of therapy and the identification of new metabolic pathways that could potentially be targeted in salivary gland dysfunction.


An experimental investigation was made of the response time and contrast characteristics of the longitudinal and transverse scattering of light in a transparent ferroelectric lead-lanthanum zirconate-titanate (PLZT) ceramic under switching conditions. These properties were determined as a function of the amplitude and duration of the switching pulses. When the amplitude was increased from 4 to 12 kV/cm, the scattering turn-on time decreased from 1 sec to 100 μsec. The contrast reached its maximum value, equal to 20, when the field was about 7 kV/cm. Depending on the pulse duration, an optical switch using this ceramic could be operated with or without memory.

Besides of conventional CAD systems, new, cloudbased CAD systems have also been available for some years. These CAD systems designed according to the principle of software as a service (SaaS) differ in some important features from the conventional CAD systems. Thus, these CAD systems are operated via a browser and it is not necessary to install the software on a computer. The CAD-data is stored in the cloud and not on a local computer or central server. This new approach should also facilitate the sharing and management of data. Finally, many of these new CAD systems are available as freeware for education purposes, so the universities can save license costs. The chances and risks of cloud-based systems will first be analyzed in this paper. Then two leading cloud-based CAD systems will be researched. During the process, the technical performance range these new systems offer for the product development will be initially checked and reviewed. For this purpose, various criteria are worked out and the CAD software is evaluated using these criteria. In addition, the criteria are weighted by their importance for design education. This allows one to conclude which capabilities the different CAD system offers for use in education.


As characteristic structural elements of several of the non-monomeric pyrrole-imidazole alkaloids, 1,1-bis(imidazolyl)-propenes were assembled in a facile manner by double Grignard reaction of metalated imidazoles with saturated esters, followed by dehydration. The presence of nitrile functions or acryl esters in the electrophile component leads to competing reactions, whereas propargyl esters are tolerated. Introduction of 2-amino groups was possible via the corresponding dimethylsulfamoyl-protected 2-azidoimidazoles, which had to be deprotected prior to hydrogenation. NOESY-based analysis revealed preferred orientation of the imidazole 5-positions towards the propenyl chain.
