Mesopore-modified mordenites as catalysts for catalytic pyrolysis of biomass and cracking of vacuum gasoil processes

Mesopore-modified mordenite zeolitic materials with different Si/Al ratios have been prepared and tested in the biomass pyrolysis and catalytic cracking of vacuum gasoil. Alkaline treatment was carried out to generate mesoporosity. Severity of alkaline treatment was found to be of paramount importance to tune the generated mesoporosity, while it significantly affected the crystallinity of treated mordenites. It was moreover observed that the alkaline treatment selectively extracted Si decreasing the Si/Al ratio of treated samples. Catalytic activity of parent and alkaline treated mordenites was studied in the pyrolysis of biomass. All zeolitic based materials produced less amounts of bio-oil but of better quality (lowering the oxygen content from ∼40% to as much as 21%) as compared to the non-catalytic pyrolysis experiments. On the other hand, it was found that the combination of mesopore formation and high surface area after alkaline treatment of the mordenite with a high Si/Al ratio resulted in the enhancement of its catalytic activity, despite the reduction of its acidity. The increment of the decarboxylation and dehydration reactions, combined with a reduction of carbon deposition on the catalyst, resulted in a remarkable decrease in the oxygen content in the organic fraction and therefore, resulted in a superior quality liquid product. Alkaline treated mordenites were additionally acid treated targeting dealumination and removal of the extra framework debris, thus generating mesopore-modified mordenite samples with stronger acid sites and higher total acidity, as candidate catalysts for catalytic cracking of vacuum gasoil. Desilicated and especially desilicated and dealuminated mordenites exhibited the highest activity and selectivity towards LCO with the best olefinicity in gases and higher bottoms conversion. Therefore, an optimized desilicated–dealuminated mordenite additive could be an interesting candidate as a component of the FCC catalyst for a high LCO yield.
Evaluation of antioxidant profile in subclinical mastitis in dairy buffaloes

The present research investigation was taken up to find out level of oxidative stress in dairy buffaloes suffering from subclinical mastitis with emphasis on Staphylococcus aureus infection at Pantnagar, Uttarakhand, India. Buffaloes were screened for subclinical mastitis (SCM) based on physical examination of udder, California mastitis test (CMT), Somatic cell count (SCC) and Differential cell count (DCC) on quarter’s milk samples. Intramammary infection (IMI) was confirmed by cultural examination of milk. A total of 30 buffaloes were included in the study and divided randomly in 3 groups consisting of healthy control, buffaloes affected with subclinical mastitis with IMI caused by S. aureus and ten buffaloes infected with pathogens other than S. aureus. There was significant increase in levels of Lipid peroxidation (LPO), superoxide dismutase (SOD), catalase (CAT), lactate dehydrogenase (LDH) and Alkaline phosphatase (ALP) while significant reduction in reduced glutathione (GSH) was observed in buffaloes with SCM. No significant difference was observed in blood urea nitrogen (BUN) concentration in buffaloes with SCM. Micromineral estimation revealed higher serum zinc and iron in buffaloes with subclinical mastitis than that of healthy control.
Potential of indigenous vegetable-fortified food products for improved human nutrition and health in West Africa

The indigenous vegetables project (MicroVeg), implemented in Nigeria and Benin Republic, focused on the development of innovative systems of production, utilization and value addition options to enhance nutrition and economic empowerment of resource-poor rural populations, especially women, at 41 selected locations. This paper reports the results of work done on value additions in Nigeria. We developed and tested the acceptability of key innovative value-added products, including vegetable-fortified bread and pastry products (cookies and chinchin), using three indigenous vegetables, namely Telfairia occidentalis f. Hooke (fluted pumpkin) Amaranthus virdis L. (local amaranth), and Solanum macrocarpon L. (eggplant). The project also developed protocol for the optimization of extraction of polyphenol from the vegetables leaves for use in fortifying a local weaning food (a maize porridge, locally called Ogi). We carried out sensory evaluation of the new products at 41 locations in southwest Nigeria with 10,250 panelists. Results from the MicroVeg project showed that bread fortified with 3% (w/w) dried vegetable leaf powders had higher nutritional properties, especially radical scavenging ability and blood pressure reductions than the regular white bread. Pastry formulations that included 3% dried vegetable leaf powders had slightly lower consumer acceptability in terms of taste and colour; however, due to the associated potential health benefits, consumers were willing to buy the vegetable-fortified products as replacements for the regular products. In order to enhance local adoption of the vegetable-fortified products, a total of 5466 persons (68% women) at 25 rural locations and 100 bakery owners were trained on these value addition innovations in 2016-2017.
Enrichment of Heavy Water in Flat-Plate Thermal Diffusion Columns of the Frazier Scheme Inclined for Improved Performance

A separation theory for the enrichment of heavy water in flat-plate thermal diffusion columns of the Frazier scheme inclined for improved performance has been developed. Equations for the best angle of inclination and maximum separation have been derived. Considerable improvement in separation is obtainable if the columns are inclined at the best angle, so that the convective strength can be properly reduced and controlled, resulting in suppression of the undesirable remixing effect while still preserving the desirable cascading effect.
AC-SUM-GAN: Connecting Actor-Critic and Generative Adversarial Networks for Unsupervised Video Summarization

This paper presents a new method for unsupervised video summarization. The proposed architecture embeds an Actor-Critic model into a Generative Adversarial Network and formulates the selection of important video fragments (that will be used to form the summary) as a sequence generation task. The Actor and the Critic take part in a game that incrementally leads to the selection of the video key-fragments, and their choices at each step of the game result in a set of rewards from the Discriminator. The designed training workflow allows the Actor and Critic to discover a space of actions and automatically learn a policy for key-fragment selection. Moreover, the introduced criterion for choosing the best model after the training ends, enables the automatic selection of proper values for parameters of the training process that are not learned from the data (such as the regularization factor $\sigma $ ). Experimental evaluation on two benchmark datasets (SumMe and TVSum) demonstrates that the proposed AC-SUM-GAN model performs consistently well and gives SoA results in comparison to unsupervised methods, that are also competitive with respect to supervised methods.
A Universal Lookup Table-Based Direct Torque Control for OW-PMSM Drives

For open-winding permanent magnet synchronous motor (OW-PMSM) system with two isolated dc voltage sources, the distribution of voltage vectors (VVs) is different under different dc-link voltage ratios. In this letter, a universal lookup table (LUT) based direct torque control (DTC) strategy is proposed for OW-PMSM drives under different conditions of the dc-link voltage ratio. The distribution criterion of VVs under various dc-link voltage ratios is analyzed and the VVs are assigned to different regions by designing a generalized region division scheme. A universal LUT is established to realize the selection of required VV in the DTC strategy. Experimental results validate the effectiveness of the proposed universal LUT-based DTC strategy for the OW-PMSM system with different voltage ratios.

Source of material 3,5-Diiodosalicylaldehyde (0.1 mmol, 36.9 mg) and 2-hydroxybenzoic acid hydrazide (0.1 mmol, 15.2 mg) were dissolved in methanol (10 ml). The mixture was stirred at room temperature for 10 min to give a clear yellow solution. Crystals were formed by gradual evaporation of the solvent over a week at room temperature (yield 71.2 %). Elemental analysis – found: C, 33.32 %; H, 2.07 %; N, 5.62 %; calculated forC14H10I2N2O3:C, 33.10%;H, 1.98%;N, 5.51%. Experimental details Atoms H2N and H4N were located in a Fourier difference map and refined isotropically, with the N—H distance restrained to 0.90(1) A and Uiso = 0.08 A. Other H atoms were positioned geometrically (d(C—H) = 0.93A, d(O—H) = 0.82A) and refined as riding, with Uiso(H) values set at 1.2Ueq(C) and 1.5Ueq(O). Discussion Schiff bases derived from the condensation reaction of aromatic carbaldehydes with primary amines are very important in coordination chemistry and biological chemistry [1-3]. The asymmetric unit of the title crystal structure comprises two Schiff base molecules. All the bond lengths are comparable to those observed for similar compounds [4-6]. The bond lengths of C7/N1 (1.276(7) A) and C21/N3 (1.278(8) A) are conform to the values for double bonds and comparable to those in other Schiff bases. The bond lengths of C8—N2 (1.359(7) A) and C22—N4 (1.361(8)A) are intermediate between those typical for the corresponding single and double bonds, suggesting some degree of delocalization in the acetohydrazide systems. The molecules display trans configurations about the C/N and C—N bonds. The dihedral angles between the two benzene rings are 21.1(5)° for molecule I and 4.7(5)° for II.Themolecules are interlinked through N–H···O, O–H···O, O–H···N and C–H···O intermolecular hydrogen bonds, forming chains running along [010].

Low-temperature (below Tg) thermal bonding of COC microfluidic devices using UV photografted HEMA-modified substrates: high strength, stable hydrophilic, biocompatible surfaces

Cyclic olefin copolymer (COC) based microfluidic devices offer unique opportunities in developing high quality chips for a variety of applications but critical issues such as the bonding strength, biocompatibility and flow need to be addressed before this can be realized. In this study, we introduce a simple microfluidic device fabricated on COC (Topas) substrates that were modified by ultraviolet (UV) photo-grafting of a hydrophilic monomer 2-hydroxyethyl methacrylate (HEMA). This water soluble acrylic monomer was used to increase the bond strength, surface wettability and hemocompatibility. Thermal bonding of the microfluidic chips was accomplished at temperatures well below the glass transition temperature (Tg) of the COC polymer. Moreover, this process produced COC microchannels with modified surfaces that had stable permanent hydrophilic properties. Therefore, it can be used for Bio-MEMS applications in electrophoretic analysis where stable electro-osmotic flow (EOF) is important. The bond strength and burst pressure of the HEMA modified chips increased significantly to 1.70 MPa and 4.20 MPa for bonding at 10 °C below Tg. The COC surfaces were characterized using contact angle, EOF measurements, and Fourier transform infrared spectroscopy. The hydrophilicities of the substrates improved significantly with increase in degree of poly-HEMA immobilization and a maximum grafting yield of about 0.13% was obtained for a short irradiation time of 12 min with 25% of HEMA monomer. In vitrofibrinogen and fluorescent labeled bovine serum albumin adsorption results indicated that the COC surface can easily be tuned against protein adsorption by controlling the grafting yield. The in vitroplatelet adhesion tests confirmed that the hydroxyl functionality greatly improved the surface hemocompatibility of COC by reducing the number and the degree of activation of the adherent platelets.
Crystallization kinetics of water below 150 K

Metastable liquid water, obtained by heating its hyperquenched glassy state above its glass→liquid transition temperature, crystallizes to cubic ice. Kinetics of this crystallization has been studied by Fourier transform infrared spectroscopy by determining the change in the spectra of stretching vibrations of the decoupled OD oscillator in 3.6 mole % HOD in H2O. The crystallization kinetics follows the equation x=[1−exp(−ktn)] and is diffusion controlled. Annealing at a temperature below its glass→liquid transition temperature alters this kinetics as the grain–growth process begins to control the early stages of crystallization.
COPROLOGICAL STUDY OF GASTROINTESTINAL PARASITES IN DAIRY CATTLE IN SULAYMANIYAH PROVINCE, KURDISTAN REGION, IRAQ

Gastrointestinal (GI) parasitic diseases are a serious problem in cattle management, and one of the most significant reasons for economic losses incattle for developing countries. This study aimed to assessthe prevalence of helminth and protozoan infection of gastrointestinal tract in local dairy cattle in Sulaymaniyah province of Iraq.A total of 1,376rectal fecal specimens of local dairy cattle were randomly collected in different regions of Sulaymaniya province. Direct fecal smear, saturated sugar flotation technique, and simple sedimentation method, were used to detect the parasitic stages in the coprological specimens.The overall prevalence rate was 60.46%. The single and mixed parasite infection rates were 37.21% and 23.25%, respectively. The infection rates of protozoa, nematodes, trematodes, and cestodes were 58.14%, 18.60%, 15.11%, and 3.48%, respectively. Among all parasites, Eimeria spp. (29.07%) was the most abundant one, followed by Buxtonella sulcata (18.60%) and Strongyle nematodes (17.44%). There was significant variation in the prevalence rates of nematodes and protozoa between various age categories and distributional regions. The results indicated that improved management system and proper anthelmintic treatment strategies should be applied in the regions to diminish the high incidence of GI parasitismin local dairy cattle.
Effect of Service Quality Toward Student Satisfaction and Loyalty in Higher Education

This study analyzes the effect of quality of services provided to the students’ in relation to their satisfaction and loyalty. Respondents in this study were seventh semester students of Universitas Muslim Nusantara Al-Washliyah, the total number of students was 312. Data analysis techniques in this study used was SEM (Structural Equation Modeling) using the SmartPLS program. The results showed that students’ satisfaction significantly mediated the correlation between academics and students’ loyalty, between non-academic and students’ loyalty, between reputation and students’ loyalty, and between campus access and students’ loyalty; on the other hand, students’ satisfaction was not significant in mediating the correlation between program issues and students’ loyalty. The findings suggest that it is necessary to improve the quality of lecturers to improve students’ academic abilities and communication skills. As far as non-academic aspects are concerned, conducting training and development efforts and increasing awareness programs for administrative staff is important. For the reputation aspect, to carry out several marketing campaigns which predict to have an effect upon students in building positive perceptions of campus has to be executed as well. Meanwhile for access aspect, it should be made certain that every student can have direct access to staff employees, and it is necessary to improve dimensions which can increase students’ satisfaction so that students are convinced of their choice of campus and then they are likely to recommend their chosen university and spread positive things about their institutions.
The Lexicogrammatical Performance by Female Legislative (DPRD) Members of West Sumatra in Communicating Via Social Media

This paper is one of the outputs of research on the Performance of Grammatically and Communication Politeness Politicians of Indonesian Women on Social Media. Political figures discussed specifically are only for women members of the legislature (DPRD). For this paper, it is limited to discuss only the performance of the lexicon (choice of words) and sentence structures used by DPRD members (district, city and province levels) throughout West Sumatra when communicating on social media (Facebook, Twitter or Instagram). This research is qualitative in nature. The data source is the social media accounts of women-only members of the West Sumatra legislature. The data was collected by print-screen from Facebook, Twitter and Instagram and converted into picture format (jpg). The print screen results are then copied into the prepared formats. Furthermore, the data were analyzed qualitatively with the content analysis method with semantic, syntactic and pragmatic theory. The results obtained show that the lexicon (diction) and structure (pattern) of sentences used vary. The choice of lexicons consists of lexicons derived from foreign languages and regional languages, in addition to Indonesian lexicons. What is interesting in the selection of this lexicon is the unusual use of words, abbreviations and acronyms. Furthermore, the sentence structure (pattern) used is minor and inversion sentence structure.
An Extended Two Step Approach to High-Resolution Airborne and Spaceborne SAR Full-Aperture Processing

The processing of synthetic aperture radar (SAR) echoes collected during radar antenna beam steering, such as in the staring spotlight, sliding spotlight, and TOPS operating modes, requires additional efforts due to the limited pulse repetition frequency (PRF). Subaperture processing is mostly used in these cases, but the complexity arising from subaperture dividing and recombination is preferably avoided. The two-step approach (TSA) is an elegant solution to full-aperture processing. Nevertheless, for high-resolution airborne and spaceborne SAR processing, the TSA is still faced with a number of difficulties, which does not occur, however, in subaperture processing. For instance, the high range bandwidth induces Doppler spectrum aliasing during the spectral analysis (SPECAN) stage of the original TSA. Moreover, the Doppler spectrum obtained in TSA, when inverse Fourier transformed back to the slow time domain, might also suffer from aliasing, which precludes the estimation and correction of the unknown residual motion error or tropospheric disturbance. In this article, we extend the TSA to address these problems and present a full-aperture processing framework to precisely focus the high-resolution airborne and spaceborne SAR data. Simulation of X-band spaceborne SAR echoes with transmission signal bandwidth of 3.6 GHz and coherent integration angle of 12.5° has validated the extended TSA (ETSA). Meanwhile, experimental X-band airborne SAR data with the same range and azimuth resolution are also processed using the ETSA, where the conventional autofocusing techniques have been smoothly incorporated.
40 nm 1T–1MTJ 128 Mb STT-MRAM With Novel Averaged Reference Voltage Generator Based on Detailed Analysis of Scaled-Down Memory Cell Array Design

The development of STT-MRAM technology is currently in progress and has been successively disclosed by major LSI vendors recently. In order to advance STT-MRAM technology and expand its areas of application, challenges relative to further device scaling need to be addressed. In this study, an increased wiring resistance in a deep sub-100 nm process by which the read operation yield is degraded was analyzed. The yield degradation was quantified by analyzing the conventional cell array using Monte-Carlo SPICE simulations. A new circuit was proposed to decrease the fail bit rate by an averaged reference voltage (<inline-formula> <tex-math notation="LaTeX">$V_{\mathrm {ref}}$ </tex-math></inline-formula>) generator. The simulated results indicated that the new <inline-formula> <tex-math notation="LaTeX">$V_{\mathrm {ref}}$ </tex-math></inline-formula> generator improved the fail bit rate by 1 order of magnitude compared to the conventional array. To demonstrate the circuit operation, a 128 Mb STT-MRAM chip was designed and fabricated using 40 nm CMOS and 37 nm MTJ technologies. For the first time, the chip measurements successfully demonstrated the operation of the proposed device-variation tolerant array architecture with the averaged <inline-formula> <tex-math notation="LaTeX">$V_{\mathrm {ref}}$ </tex-math></inline-formula> generator, presenting a 30 ns read access time.
Accounting Information System, Internal Control System, Human Resource Competency and Quality of Local Government Financial Statements in Indonesia

This study seeks to determine the effect of the application of accounting information system (AIS), internal control system, and human resource (HR) competency on the quality of local government financial statements (FS). This study uses agency theory and compliance theory. Agency theory is used to explain that there is a link between the society as the principal and the government as the agent. Compliance theory is a theory, which states that every agency is obliged to comply with regulations because the law-drafting authority has the right to dictate behavior. The population in this study were employees of the financial division of local government organizations in one of the districts in Central Java, Indonesia. The total samples in this study was 106 respondents. The data used are primary data taken from distributing questionnaires to respondents. The method of analysis used to test the hypothesis was multiple linear regression analysis. The results of hypothesis testing indicate that HR competency has an effect on the quality of FS; however, the application of AIS and internal control system has no effect on the quality of FS. The implication of this research underlines the importance of HR competency to improve the quality of local government FS.
