A transient kinetics study of char gasification in carbon dioxide and oxygen

Transient (unsteady-state) kinetics, a relatively new technique for studying noncatalytic gas/solid reactions, has been used successfully to further our understanding of char (carbon) gasification. It provides the unique capability of separately determining the reaction rate constant (site reactivity or turnover frequency) and the number of active sites participating in the reaction (reactive surface area). Its application to the uncatalyzed gasification of coal-derived chars and polymer-derived carbons is illustrated. In particular, the heretofore elusive quantitative understantding of their reactivity variations with conversion has been achieved for gasification in both carbon dioxide and oxygen
Double perovskites containing hexavalent molybdenum and tungsten: synthesis, structural investigation and proposal of a fitness factor to discriminate the crystal symmetry

Double perovskites A II 2 B II B VI O 6 (A II =Ba, Sr, Ca; B II =Mg, Ni, Co, Cd, Ca; B VI =W, Mo, W 0.5 Mo 0.5 ) have been synthesized and their crystal structures investigated by powder X-ray diffraction measurements. In order to discriminate the crystal systems of the double perovskites, a fitness factor is proposed which corresponds to the size matching between the A cation and the cubo-octahedral cavity formed by eight BO 6 octahedrons. The fitness factor can discriminate the crystal systems of obtained compounds more exactly than the well known tolerance factor.
Butterfly pea flower extract as an alternative dye in cytological canine mast cell tumor staining

Mast cell tumors (MCTs) are the most common skin tumors in dogs. Laboratory diagnosis of MCTs has been established by many techniques. The dyes generally used for tissue staining, including MCTs, are synthetic dyes, however, the global interest in using eco-friendly natural dye has become a significant matter. We focused on the butterfly pea (Clitoria ternatea L.) which is locally available. Limited studies are known about their efficacy as a tissue stain. The aim of this study was to investigate the staining ability of butterfly pea flower extract in cytological canine MCTs. The dried petals were ground into powder and dissolved in acidified ethanol to obtain the crude extraction. After filtration, this was added with mordant, 2.5% aluminium chloride, before staining. The methanol-fixed cytological samples of diagnosed MCTs were stained with the dye extract for 30 minutes, washed with distilled water and observed under light microscope initially, and after the counterstaining, with hematoxylin. The slides were stained with Giemsa, Toluidine blue and Diff-Quick stains to compare with the dye extract. The other round cell tumors including canine transmissible venereal tumor (TVT) and melanoma were also stained with the dye extract to compare with the MCTs. The results revealed a bright pink color specifically stained in the MCT granules. However, Giemsa, Toluidine blue and Diff-Quick staining shown their specific stain colors in the granules in larger numbers. The dye extract staining was not detected in either TVT or melanoma. Improvement of the dye extraction and staining conditions may provide additional staining outcomes, thus it may be possible to serve as an alternative natural dye for future application in cytological canine MCT diagnostics.
Exchange Rate Volatility and Foreign Direct Investment in Nigeria: An E-Garch Approach

Article History Received: 22.07. 2018 Accepted: 06.08. 2018 Published: 30.08. 2018 Abstract: This study seeks to examine the relationship between Foreign Direct Investment (FDI) and Real Effective Exchange Rate (REER) volatility in Nigeria. Using annual time series data from 1980 to 2016, the study adopted the Exponential GARCH model, Ordinary Least Squares (OLS) estimation technique and the Error Correction Mechanism. The major findings of the study reveal that there is a negative correlation between Nigeria’s past and future REER, which further implies that negative shock has less effects on exchange rate volatility when compared with a positive shock. It also found that exchange rate has a very significant effect on FDI in Nigeria while there also exists a long-run relationship between them. The study therefore advocates for a strong foreign exchange policies by the CBN to attract FDI. It also suggests that CBN should be keen on monitoring the financial news in the economy as it could heighten exchange rate and financial market volatilities; which may not be good for the economy’s overall growth and development in the long-run.
Differential effects of press vs. pulse seawater intrusion on microbial communities of a tidal freshwater marsh

Tidal freshwater marshes (TFMs) are threatened by seawater intrusion, which can affect microbial communities and alter biogeochemical processes. Here, we report on a long‐term, large‐scale manipulative field experiment that investigated continuous (press) and episodic (pulse, 2 months/yr) inputs of brackish water on microbial communities in a TFM. After 2.5 yr, microbial diversity was lower in press treatments than in control (untreated) plots whereas diversity in pulse plots was unaffected by brackish water additions. Sulfate reducer abundance increased in response to both press and pulse treatments whereas methanogens did not differ among treatments. Our results, along with other lab and field measurements that show reduced soil respiration and extracellular enzyme activity suggest that continuous seawater intrusion will decrease macrophyte C inputs that reduce bacterial diversity in ways that also diminish ecosystem carbon cycling.
Associating Features by Common Space Embedding via Non-negative Tri-factorization

: In this paper, we consider the problem of associating features from diﬀerent datasets with a small set of hints. That is, given two object sets with their own feature sets, the learning task is to (cid:12)nd associations between features, where part of associations is already presented as hints. The proposed method is based on an idea: With the given associations, all the objects can be clustered into object clusters. By representing features with the object clusters, some new associations between remaining features can be determined. By repeating this process, we are able to get all the feature associations. We formalized this problem with laplacian constrainted Non-negative Matrix Tri-factorization (NMF). We embedded the features into a common space, where if two features are near to hints, they will also be near to each other.

Explaining the Mediating Role of Knowledge Management between Organisation’s Characteristics and Employee’s Performance: A Public Sector Perspective

This paper aims to investigate the mediating role of knowledge management between organizational culture, structure, strategy, and employee and organisational performance. There is a significant research work on Knowledge Management (KM) globally; however, there is a dearth of research in contextualizing the concept in the Middle East. Therefore, adopting a multiple case-based approach, this paper conducted 478 surveys in five public organizations in Kuwait. The results suggested that KM could mediate the impact of organizational strategy and HRD structure. Surprisingly, organizational culture emerged as the only construct that remained uninfluenced by knowledge management practices. This research makes a vital contribution to the under-researched knowledge management concept in the region and the relevant cognitive understanding of social practice in relation to the HRD. It, therefore, proposes an integrative framework which specifies the conceptual linkages between organization characteristics and potential performance.
Free Choice Intake, Growth and Digestibility Responses by West African Dwarf Does Fed Pulverised Maize-Cob Based Diets

In an effort to mitigate the effect of dry season on ruminant feeding, the use of alternative feed resources such as maizecob, cassava peel and brewers’ grain was investigated. Using twelve West African Dwarf (WAD) goats of average weight 9.05 ± 0.5 kg, the free choice intake, growth and digestibility were used as response criteria to pulverized maize-cob based diets {pulverized maize-cob/cassava peel (PMC/CsP), pulverized maize-cob/brewers’grain (PMC/BG) and pulverized maize-cob/brewers’grain/cassava peel (PMC/BG/CsP)}. Free choice intake was determined by cafeteria method using two indices; Coefficient of Preference (CoP) and Percentage preference (Pp) while for the growth study, animals were randomly allotted to the three dietary treatments, having four animals per treatment and digestibility of the diets was also evaluated. Results revealed crude protein and neutral detergent fibre contents range of 14.66 – 21.18% and 40.0151. 14% respectively among the diets. Free choice intake of diets was significantly (P<0.05) affected by the dietary treatments. The PMC/CsP diet was inferred acceptable as the CoP was above unity (2.30), with the highest preference value (38.47%) and was ranked 1. Intake, weight gain and feed/gain ratio were significantly (P<0.05) influenced by the dietary treatments. Animals fed PMC/CsP recorded the highest dry matter intake (309.45g/day) and lowest intake (290.27g/day) was obtained by animals on PMC/BG. Weight gain and feed/gain ratio ranged from 20.55-25.11g/day and 12.32–14.25 respectively. Digestibility of nutrients was significantly (P<0.05) different across the treatments with diet PMC/BG having the highest dry matter (50.26%), crude protein (58.41%) and neutral detergent fibre (43.48%). It was concluded that pulverized maizecob based diets have the potential to sustain goat production during the period of forage scarcity.
Molecular systematics and evolutionary relationships of some inland gilled basidiomycetes from the Himalayan moist temperate forests of Pakistan based on rDNA marker

Molecular systematics based on molecular markers has revolutionized traditional taxonomy because of its comprehensive identification, precise methodology and reliable evolutionary affinities. In this study, the phylogeographical history data based on DNA analysis of eleven (11) basidiomycetous fungal species belonging to four different genera of four families from Pakistani Himalayan forests has been presented. In the phylogenetic analysis based on ITS-rDNA marker, five species of Lepiota (Agaricaceae), L. acutesquamosa, L. cristata, L. brunneoincarnata L. subincarnata and L. himalayensis, two species of Hebeloma (Hymenogasteraceae), H. mesophaeum and H. theobrominum showed genetic similarity and evolutionary affinities with European species while two (2) Inocybe (Inocybaceae), Inocybe sp. SR19 and I. cf. rimosa and two (2) species of Gymnopus (Marasmiaceae), Gymnopus sp. 1and Gymnopus sp. 2 showed more symplesiomorphic characters with western and Australian species. Close affinities of Pakistani species (endemic and non-endemic) with European and American species can be related with common evolutionary history in Eurasia and African continents. The sympatric and allopatric isolations due to continental drift and climate change, generated genetic differences among local mycoflora from the western hemisphere and therefore the Pakistani species mostly showed close affinities with western species as both have common origin.

AIFM: High-Performance, Application-Integrated Far Memory

Memory is the most contended and least elastic resource in datacenter servers today. Applications can use only local memory—which may be scarce—even though memory might be readily available on another server. This leads to unnecessary killings of workloads under memory pressure and reduces effective server utilization. We present application-integrated far memory (AIFM), which makes remote, “far” memory available to applications through a simple API and with high performance. AIFM achieves the same common-case access latency for far memory as for local RAM; it avoids read and write amplification that paging-based approaches suffer; it allows data structure engineers to build remoteable, hybrid near/far memory data structures; and it makes far memory transparent and easy to use for application developers. Our key insight is that exposing application-level semantics to a high-performance runtime makes efficient remoteable memory possible. Developers use AIFM’s APIs to make allocations remoteable, and AIFM’s runtime handles swapping objects in and out, prefetching, and memory evacuation. We evaluate AIFM with a prototypical web application frontend, a NYC taxi data analytics workload, a memcachedlike key-value cache, and Snappy compression. Adding AIFM remoteable memory to these applications increases their available memory without performance penalty. AIFM outperforms Fastswap, a state-of-the-art kernel-integrated, pagingbased far memory system [6] by up to 61×.
DETERMINATION OF HEAVY METAL IN SAMPLES OF TIRMANIA NIVEA FUNGI IN DIFFERENT SOILS

Tirmania nivea (Desf.) Trappe,1971 has high commercial value. This study was aimed to assess the quality and suitability of Tirmania nivea for human use by determining their heavy metals content and susceptibility to heavy metals accumulation. Concentrations of lead (Pb), Cadmium (Cd), Chromium (Cr) and Nickel (Ni) were tested in different fungus samples grown in different soils of the semi-arid regions of Iraq. Heavy metals concentrations were found in range of level ordered from high to low Cr < Ni < Cd < Pd. The soil contents of cadmium were about five times and the firm was about one and a half times above the global scale (0.1 to 1) mg/kg, while Cr, Ni and Pb concentrations were lower than the reference ranges in the United States and Chinese soil (70, 20, 300) mg/kg respectively. Transfer factor from soil to the fruits was more than one except for Cr. The high transport rate of this mineral in the buds of Tirmania nivea makes it suitable to extract the mineral from the soil. There was a significant linear correlation between the concentration of heavy metals in the fruit of T. nivea and those in the study soil except for Cr. This finding suggests that T. nivea can be considered a biological indicator of soil heavy metal contamination. Concentrations of heavy metals in the current study below the danger state of human health that makes Tirmania nivea (Al Kamah) suitable for use as a food.
Functionalization of Graphene Oxide and its Biomedical Applications

Graphene oxide (GO) offers interesting physicochemical and biological properties for biomedicine due to its versatility, biocompatibility, small size, large surface area, and its ability to interact with biological cells and tissues. GO is a two-dimensional material of exceptional strength, unique optical, physical, mechanical, and electronic properties. Ease of functionalization and high antibacterial activity are two major properties identified with GO. Due to its excellent aqueous processability, amphiphilicity, surface functionalization capability, surface enhanced Raman scattering (SERS), and fluorescence quenching ability, GO chemically exfoliated from oxidized graphite is considered a promising material for biological applications. In addition, due to π-π* transitions, a low energy is required for electron movement, a property important in Biosensor and Bioimaging applications of GO. In this article, we present an overview of current advances in GO applications in biomedicine and discuss future perspectives. We conclude that GO is going to play a vital role in Biomedical applications in the near future.
A Hierarchical Routing Method based on Fog Technology using the Grey system Theory in Internet of Things

Considering the great growth of IoT networks and the need for highly reliable networks and also considering the manufacturing divides of IoT equipment which are highly limited by their memory, processing power and battery; we need a highly efficient routing for guaranteeing our network's high life span. So, this paper has suggested an efficient energy routing method based on the overlapping clustering method which is inspired from the Grey theory. The Overlap clustering method means that some Things collect data that must be sent to two or more Fog nodes for processing. In the suggested method the best node is selected as the cluster head based on factors such as remaining energy, distance, link expiration time, signal power for receiving data from things by the Fog nodes. In the next step the Fog node's data are sent in a hierarchical method using a symmetrical tree of processed data to the server. Thus, the main issue here is making using a proper routing method for data sending to the Cloud that doesn't just focus on energy, but also considers other factors such as delay and network life span. The simulation results show that the HR-IoT reduces the average end to end delay more than 17.2% and 23.1%, decreases the response time more than 20.1% and 25.78% and increase packet delivery rate more than 23.1% and 28.78% and lifetime more than 25.1% and 28.78% compared to EECRP and ERGID approaches.
INHIBITORY EFFECTS OF EMULSIFYING SALTS STPP AND NACL ON KLEBSIELLA PNEUMONIAE CONTAMINATION SOFT CHEESE COW'S SAMPLES COLLECTED FROM VENDED IN BABYLON GOVERNORATE, IRAQ

Milk and milk products are highly vulnerable to numerous food borne chains pathogens such as Klebsiella pneumoniae, which make these products as possible vehicle to transfers these bacteria, so this study was carried out to detect the level of contamination of cattle product as a measurement for the exposure of consumers in one of the most common food chains in Babylon province, during the period from March to June 2019. Klebsiella pneumoniae . were isolated from locally cattle milk and soft cheese. A total of 81(18.7%) out of 15 of locally cattle milk and soft cheese gave positive results for Klebsiella pneumoniae Results of susceptibility test revealed high prevalence of resistance in MRSA isolates to four or more antimicrobial agents with which eight antibiotic resistance profiles (ARPs) were presented by these isolates. Our study has shown that locally milk and soft cheese in several markets in the province of Babylon has been highly tainted by Klebsiella pneumoniae throughout the period of the study and when take into consideration that the existence of multiple drug-resistant Klebsiella pneumoniae in milk product may constitute a serious danger for the health of the consumers, consequently these outcomes are very important from the public health viewpoint.
Evaluation of Reference-Crop Evapotranspiration Models, Crop Evapotranspiration Methods and Water Supply Methods for the Determination of Crop Coefficient of Kenaf

Field and pot experiment were conducted in University of Agriculture, Abeokuta, to develop crop coefficients (Kc) for kenaf. Efficiency of lysimeters and Time Domain Reflectometery (TDR) in the measurement of Crop evapotranspiration (ETc) and the Cropwat and Instat+ models in estimating reference evapotranspiration (ETo) were evaluated. The experiment involved three varieties of Kenaf (Ifeken 100, Cuba 108 and Tainung 2) and two water supply methods (rain-fed and irrigation). Physiological parameters and Kc estimated during the different phenological stages of kenaf grown were analyzed with respect to treatments using inferential statistics. The result showed that Cropwat and Instat+ were related (P < 0.05) in their estimation of ETo. A strong positive linear relation (R2= 0.72, p < 0.05) was recorded between lysimeters and TDR measured crop evapotranspiration both on the field and in the container experiment irrespective of variety and water supply method. The Kc from this study were highest in mid-season (0.9 1.2), followed by crop development period (0.5 0.8), then late period (0.3 – 0.7) and finally the initial stage (0.2 0.4) for all varieties of crop shown irrespective of water supply methods. The Kc for the total growth period is estimated to ranged between 0.6 0.7. The Kc determined by lysimeter were about 10% higher than the TDR during the late mid period and the late period. The field determined Kc were slightly higher than those in the container grown crop due to container surface area lower than the ground area for planting of crop. The study further confirmed that variety selection of kenaf, water supply method and their interaction does not significantly (p> 0.05) influenced crop coefficient during the trial. It could be concluded that investigating Kc provides a scientific basis for determining the extent to which the water availability will satisfy water requirement of kenaf during the different phenological stages.
A New Soil Sampling Design in Coastal Saline Region Using EM38 and VQT Method

Spatial sampling design based on the variability and distribution of soil properties is an important issue with the progress in precision agriculture and soil ecology. Electromagnetic induction (type EM38) and variance quad-tree (VQT) method were both applied to optimize the sampling scheme of soil salinity in a coastal reclamation field in north Jiangsu Province, China. Apparent soil electrical conductivity (ECa) measured with EM38 was used as an ancillary variable and the spatial distribution of ECa was used as priori information. The process and result of VQT algorithm analysis was illustrated and the obtained sampling strategy was validated using observed soil salinity. Then the spatial precision and sampling efficiency were evaluated. The result indicated that the spatial distribution of soil salinity produced with the VQT scheme was quite similar to that produced with total sampling sites, while sampling quantity of the former was reduced to approximately 1/2 of the latter. The spatial precision of VQT scheme was considerably higher than that of traditional grid method with respect to the same sampling number, and fewer samples were required for VQT scheme to obtain the same precision level. A 17.3% increase in sampling efficiency was achieved by VQT over grid method at the precision level of 90%. The VQT method was proved to be more efficient and economical because it can sample intensively or sparsely according to variation status in local areas. The associated application of EM38 and VQT method provides efficient tools and theoretical basis for saving sampling cost and improving sampling efficiency in coastal saline region and enriching soil ecology.
