Optimal Method for Production of Amorphous Cellulose with Increased Enzymatic Digestibility

In this paper, a simple and cheap method for producing of amorphous cellulose was studied by treating the initial cellulosic material (MCC and waste paper) with a cold solvent, such as aqueous solution of 7% NaOH/12% Urea, at the various ratios of the solvent to cellulose (v/w) (R). If was found that after treatment of cellulose materials with the solvent at R ≥5, a completely amorphous cellulose (AC) is formed. Due to high digestibility, the AC with concentration of 50 g/L is converted to glucose almost completely for 48 h under the action of cellulolytic enzyme CTec-3 with a dose of 30 mg/g solid sample. Such sample can be used as an amorphous standard in the study of crystallinity degree and enzymatic hydrolysis of various types of cellulose and lignocellulose. It was found that enzymatic saccharification is most advantageous to carry out at elevated concentrations of AC, 150 g /L. Due to high cost of MCC, it is preferable to use a cheap cellulose raw material, such as mixed waste paper (MWP), for the commercial production of AC and glucose. The resulting glucose can find application in biotechnology as a promising nutrient for various microorganisms.

Mafic to ultramafic intrusions of the Qullinaaraaluk suite (Q-suite) were emplaced into the Ungava craton of the Northeastern Superior Province during an episode of intense igneous activity and crustal reworking from c. 2 74 to 2 70 Ga. Orthopyroxene-rich Q-suite intrusions from the Hudson Bay Terrane and southwestern Rivie' re ArnaudTerrane, and orthopyroxene-poor Q-suite intrusions from the north^central Rivie' re Arnaud Terrane indicate the existence of at least two Q-suite magma types: a subalkaline magma parental to the orthopyroxene-rich intrusions and a transitional magma parental to the orthopyroxene-poor intrusions. Both types of intrusions are characterized by light rare earth element (LREE)-enriched, high field strength element (HFSE)depleted trace element profiles that reflect, in large part, contamination by the tonalite^trondhjemite^granodiorite-dominated crust. Near-chondritic to strongly sub-chondritic initial eNd(2 72 Ga) values (þ2 to ^10) of the Q-suite intrusions reflect the combined effects of both the amount of crustal contamination and the agedependent isotopic composition of the contaminant. The inferred trace element profiles of the uncontaminated Q-suite magmas were probably flat to LREE-depleted. The transitional magmas that produced the least evolved dunitic cumulates of the Q-suite were ferropicrites (MgO 14 wt %, FeOTOT 17 wt %). In contrast, the magmas parental to the primitive Q-suite harzburgites were Fe-rich, high-Mg basalts (MgO 11wt %; FeO 14 wt %). The high Fe contents of the Q-suite magmas are incompatible with derivation from a pyrolitic mantle [Mg-number 0 90, Mg/ (MgþFeTOT)] and require sources significantly enriched in iron (Mg-number 0 79). Both magma types are also characterized by relatively low Ni contents suggesting derivation from source regions depleted in Ni relative to pyrolitic mantle peridotite. Differences in the major element compositions of the subalkaline and transitional parental magmas may reflect compositional diversity among the Fe-rich mantle sources. Comparisons with melting experiments on compositions analogous to the Martian mantle suggest that the Q-suite magmas may rather be generated by different degrees of melting of a common source with an Fe content slightly lower than that of the Homestead L5 ordinary chondrite (Mg-number1⁄4 0 77). The Fe-rich picritic to high-Mg basaltic magmas last equilibrated with garnet-free harzburgitic to lherzolitic residues at upper mantle pressures ( 5 GPa). The craton-wide occurrence of c. 2 72^2 70 Ga Q-suite mafic to ultramafic plutons suggests that underplating by Fe-rich mantle melts may have had a key role in the c. 2 74^2 70 Ga cratonization of the Northeastern Superior Province.
Investigating the effect of governance on unemployment: a case of South Asian countries

Abstract This study aims to investigate the short-run and long-run relationship between economic variables and the unemployment rate in South Asian countries. A panel vector error correction model is used to establish the long-run and the short-run relationship between the unemployment rate and the selected economic variables. Data were collected from WDI, WGI, and FDSD for the years 1994–2016. In order to determine the direction of the relationship, the Granger causality test was used. Impulse response functions (IRFs) and forecast error variance decomposition were used to assess the stability of the relationship between the unemployment rate and economic variables over time. The finding of the study showed a negative and significant relationship at the 5% level of significance between governance, internet users, mobile cellular subscriptions, fixed broadband subscriptions, and human capital and the unemployment rate of South Asian economies. On the other hand, financial activity (credit) and population growth had a positive and significant relationship with the unemployment rate. Finally, the Granger causality test showed bidirectional causality between governance and unemployment rate, while internet users and fixed broadband subscriptions showed unidirectional causality with the unemployment rate; furthermore, population growth, financial activity (credit), mobile cellular subscriptions, and human capital showed no causality in the short run.
Heart rate variability for assessing stress in cows.

Measurement of heart rate variability (HRV) is a non-invasive technique that can be used to investigate the functioning of autonomic nervous system, especially the balance between sympathetic and vagal activity. HRV is measured by determining the constantly changing temporal distance between succeeding heartbeats (R-R intervals). Five lacting cows, well trained to blood sampling were challenged with an intramuscular single dose (0.5 μg/kg) of ACTH (Synacthen Depot). HRV was measured for each cow for 5 min, at 0 h (before treatment) and every 30 min for 2 h. HRV parameters were analysed in the time domain, frequency domain and nonlinear components. Blood samples (10 mL) were collected from the coccygeal vein of all cows at 0, 30, 60, 90 and 120 min, after the measurement of HRV, for serum cortisol. The heart rate of cows increased significantly (P<0.05) under the influence of Synacthen administration. All computed time domain parameters declined significantly after ACTH administration. The decline of root mean square of successive interbeat interval differences (RMSSD) was more pronounced than that for standard deviation of all interbeat interval (SDNN), after ACTH administration. The power of lowfrequency component divided by power of the high-frequency band (LF/HF) increased also within 30 min of administration of ACTH. All nonlinear parameters (%DET and %REC) exhibited a significant rise 30 min after ACTH administration. Serum cortisol concentration also increased (P < 0.05) within 30 min of administration in cows. The nonlinear parameters were most important to indicate the level of stress in cows. HRV is a valuable physiological indicator for stress in cows.
Pragmatic functions of repetitions in spontaneous spoken dialect discourse

Abstract Repetition is a natural phenomenon employed to perform a variety of cognitive, psychological, interactional, stylistic, didactic and pragmatic functions in spoken and written discourse. Adopting the method of discourse analysis, the study attempts to explore the pragmatic functions of repetitions as used in spoken dialect narrative discourse. On a propositional level, only those repetitions which establish and maintain co-reference are necessary, all other forms seem to be redundant. However, if we take into account their pragmatic functions, they are not, as the data gathered in the study show. In fact, speakers use them, deliberately or not, as an effective communication strategy in the following functions: to extend the planning time to find a suitable lexeme, to enhance the importance of a lexeme, to emphasize the length of an event, after an interruption, to eliminate uncertainty and to confirm the correctness of the co-speaker’s statement. They also reveal the speakers emotions, like his/her emotional shock, and are used as a part of the so-called conversational duet. The data include the transcripts of the interviews with 6 dialect speakers in the Brda/Collio region, western Slovenia.
A new method for graph stream summarization based on both the structure and concepts

Abstract Graph datasets are common in many application domains and for which their graphs are usually massive. One solution to process such massive graphs is summarization. There are two kinds of graphs, stationary and stream. For stationary graphs, a number of summarization algorithms are available while for graph stream there is no a comprehensive summarization method that summarizes a graph stream based on the structure, vertex attributes or both with varying contributions. This is because of challenges of graph stream, which are volume of data and changing of data over time. In this paper, we propose a method based on sliding-window model for which summarizes a graph stream based on a combination of the structure and vertex attributes. We proposed a new structure for summary graphs and also proposed new methods for comparing two summary graphs. To the best of our knowledge, this is the first method that summarizes a graph stream based on both the structure and vertex attributes with varying contributions. Through extensive experiments on real dataset of Amazon co-purchasing products, we have demonstrated the performance of the proposed method.
Probabilistic Vehicle Reconstruction Using a Multi-Task CNN

The retrieval of the 3D pose and shape of objects from images is an ill-posed problem. A common way to object reconstruction is to match entities such as keypoints, edges, or contours of a deformable 3D model, used as shape prior, to their corresponding entities inferred from the image. However, such approaches are highly sensitive to model initialisation, imprecise keypoint localisations and/or illumination conditions. In this paper, we present a probabilistic approach for shape-aware 3D vehicle reconstruction from stereo images that leverages the outputs of a novel multi-task CNN. Specifically, we train a CNN that outputs probability distributions for the vehicle's orientation and for both, vehicle keypoints and wireframe edges. Together with 3D stereo information we integrate the predicted distributions into a common probabilistic framework. We believe that the CNN-based detection of wireframe edges reduces the sensitivity to illumination conditions and object contrast and that using the raw probability maps instead of inferring keypoint positions reduces the sensitivity to keypoint localisation errors. We show that our method achieves state-of-the-art results, evaluating our method on the challenging KITTI benchmark and on our own new 'Stereo-Vehicle' dataset.
Prevalencia de hipovitaminosis D y factores asociados en adolescentes de una ciudad capital del noroeste de Brasil

Background: Hypovitaminosis D is a frequent problem in the world and can be influenced by several factors. Objective: To estimate the prevalence of hypovitaminosis D and associated factors in adolescent students of a capital city of northeastern Brazil. Methods: Cross-sectional epidemiological study assessing 220 school adolescents of both sexes aged 15 to 19 years. A questionnaire was applied to assess sociodemographic (skin color, mother's education and receiving social benefits) and behavioral data (number of hours of sleep per day, sun exposure, physical activity and dietary vitamin D intake). Anthropometric nutritional status was assessed by BMI (body mass index) for age. Serum 25 (OH) D concentrations, PTH and serum calcium were measured by blood samples. We identified individuals with hypovitaminosis D as those with 25 (OH) D < 30 ng/dL. The analysis of factors associated with hypovitaminosis D was performed by simple and multivariate Poisson Regression. Results: The prevalence of hypovitaminosis D was 57.3%. The female population had a significantly higher prevalence than the male. In the final adjusted model, the variable independently associated with hypovitaminosis D in females was the lowest serum calcium concentrations, and for males it was BMI, in which adolescents who had overweight/obesity were 2.4 times more likely to have hypovitaminosis D than the eutrophic ones. Conclusions: The present study found a high prevalence of hypovitaminosis D in the analyzed population, especially in female adolescents. In addition, the factors independently associated with hypovitaminosis D were found to be overweight/obese in boys and low calcium concentrations in girls.
CFD parametric study of the influence of number and arrangement of meat carcasses in the thermal performance of refrigeration rooms

This paper describes the numerical results of a CFD parametric studies of the influence on the thermal performance of a cold room by (1) the number and arrangement (n = 6, 9, 18, 30 and 40) of meat carcasses hanging in an airway; (2) the air temperature in the antechamber (T = 5oC; 14oC and 22oC); and of (3) opening the door of the cold room. The case studies were tested in a real facility. A steady state 3D CFD model of the cold room is developed, allowing the detailed evaluation of the airflow and heat transfer for each case study. The thermal conduction within the meat carcasses is also predicted. The numerical predictions show that the average air temperature inside the cold room as well as the average carcass temperatures increase with the number of products and depend on the arrangement of the carcasses in the airway. A minimum space between carcasses is required to improve the refrigeration process. Similarly, the heat load of the cold room increases with the air temperature of the antechamber and when the door of the cold room is opened. The carcasses temperature profile becomes less uniform when the door is opened, being the temperature of carcasses located near the door strongly affected. These parametric studies allow to evaluate details of the air flow and heat transfer by convection and conduction inside goods that can contribute to the design of cold rooms in order to focus on the improvement of thermal performance and consequently of food safety and energy efficiency.

Climate Variability at Ludhiana

Annual, seasonal, monthly and weekly variabilities in temperature and rainfall were analyzed from daily meteorological data of the past 30 years (1970–99) for Ludhiana located in the central plain agroclimatic zone of Punjab. Two distinct crop growth seasons of kharif (1 May to 31. October) and rabi (1 November to 30 April) were characterized for seasonal trends. The data were analyzed for normals, standard deviation (s.d.), coefficient of variation (c.v.), extreme values and five yearly moving averages. The analysis of the data revealed that the climate has changed slightly over the past 30 years. The minimum temperature has increased at the rate of 0.07°C per year during the past 30 years. However, the maximum temperature shows a slight decrease (at the rate of 0.02°C per year) during the same period. An increasing trend is also apparent in the annual as well as kharif Veason rainfall over the past 30 years.
Roust Power System Stabilizer Design Using Kharitonov’s Theorem: A Case Study

This paper proposes a robust power system stabilizer(PSS) for a steam synchronous generator in Barka II power station. The PSS should be capable of damping small-disturbance oscillations (inherently existing in power systems due to e.g. load changes, lines switching.etc.) within a certain settling time for different load conditions. Also, the proposed PSS must have the conventional structure and its parameters must not be violated. To achieve this goal, robust control provides many advantages. The suggested controller is tuned by the Kharitonov’s theorem and uses the standard structure employed in industry. The problem is cast into a nonlinear constrained optimization problem to achieve the desired settling time without violating the practical values of the controller parameters. Performance of the robust PSS is evaluated by several simulations in the presence of system uncertainty due to load changes.
LARGE-EDDY SIMULATION OF ACCELERATING BOUNDARY LAYERS OVER ROUGH SURFACES

Large-eddy simulations (LES) are carried out to study the combined effects of roughness and pressure gradient in boundary layer flows, where the high acceleration facilitates flow reversion to the quasi-laminar state. First, validations of the immersed-boundary scheme and the LES resolution are carried out on rough-wall open-channel flows. Then the roughness model is applied to boundary layers subject to strong acceleration, leading to relaminarization and retransition. The roughness (represented by the roughness Reynolds number k+) counteracts with the favourable pressure gradients (FPGs): while flow acceleration tends to stabilize the flow by significantly damping turbulent motions in the vertical and spanwise directions and produces one-dimensional turbulence after the high-acceleration region, the roughness elements increase the turbulent mixing in the wall layer, reducing the stability of the low-speed streaks, and leading to earlier retransition to turbulence.
Guidelines for the prevention, diagnosis and management of cryptococcal meningitis and disseminated cryptococcosis in HIV-infected patients : guideline

While the developed world has seen a substantial decline in incidence rates of CC after the advent of highly active antiretroviral treatment (HAART), the enormity of the burden of AIDS on the African sub-continent and the anticipated delays in achieving full coverage of antiretroviral therapy (ART) programmes imply that CC will continue to cause mortality among our population for years to come. The prognosis of patients with cryptococcal meningitis was very poor prior to the availability of ART, but present survival rates in the context of ART co-administration are much improved. Consequently it has become essential to improve the initial acute management of CC in order to maximise the patient's chances of initial survival and subsequent entry into the ART treatment programme. Existing international guidelines for the management of cryptococcosis are written for different geographical and clinical contexts and may be impracticable for implementation in sub-Saharan Africa given limited availability of drugs and other resources.

Unconventional Photolithography with Self-Assembled Plasmonic Nanostructures

To overcome the diffraction limit of conventional optical photolithography the electromagnetic design of a novel plasmonic bow-tie nanostructure is presented. The proposed structure can be fabricated by self-assembling dielectric spheres on a layer of photoresist, followed by metal deposition and removal of the spheres. The metallic bow-tie nanostructure can focus light to expose the photoresist. The intensity distribution in the photoresist is calculated by solving Maxwell’s equations, to predict the clearance profile after development. The simulations provide the size of the nanospheres, the optimum thickness of the metallic bow-tie antennas and the photoresist, the optimum wavelength of the illumination and the development conditions, in order to obtain the desired pattern of holes arranged in honeycomb lattice.
