Application of Artificial Neural Networks and Adaptive Neuro-Fuzzy Inference Systems to Predict Activated Carbon Properties for Methane Storage

BET surface area and micropore volume are important factors for improving methane storage in activated carbons (ACs). Specification and optimization of carbon structures are vastly examined by different researchers. However, because of complex relations between independent and dependent variables, the proposed statistical and mathematical models are not satisfactory. In this paper, the specifications of some ACs synthesized by chemical activation methods are predicted. The effects of parameters such as agent type, activation time, activation temperature, impregnation ratio and heating rate on the BET surface areas and micropore volumes of ACs are also analyzed. Two models of artificial neural networks and adaptive neuro-fuzzy interference systems are used. Later on, a number of data on other ACs reported by several researchers are used for the model validation. The obtained results from these two models are found to be satisfactory. The coefficients of determination for these models were 0.982 and 0.984, respectively. Through this modelling of AC production process, which was the main purpose of this study, the specifications of ACs may be obtained without spending extra time and expenses.
The Impact of Skill Endowments and Collective Bargaining on Knowledge-Intensive Greenfield FDI

This paper assesses the contribution of skilled employment and labour market conditions to the ability of attracting knowledge intensive and manufacturing greenfield FDI. We carry out our analysis by controlling for a wide range of labour market features, such as the collective bargaining coverage rate, the non-wage labour costs, and the occupational skills of employment. It departs from the existing literature in two respects. First, it deepens the analysis on the effect of labour market regulations and skills endowments on greenfield FDI inflows. Second, it investigates the extent to which labour market characteristics matter for discriminating among ‘resource-seeking’ and ‘efficiency/strategic asset-seeking’ greenfield FDI activities (e.g. manufacturing versus knowledge-intensive foreign investments, respectively). Our empirical analysis suggests that the quality of employment and the technological knowledge base have different impact on the location of knowledge-intensive and on low-cost labour-intensive manufacturing foreign investments. Further, associating the collective bargaining coverage of unions with the level of regulation in the labour market, our results can provide insights into the effectiveness of labour market policies that aim at attracting knowledge-intensive investments.

The Effects of Coexistent Psychiatric Disorders in Patients Operated on for Acute Aortic Dissection on Postoperative Mental Health Status and on Mid-Term Time Period

Background and aims of the study: Although relationships between ischemic heart disease and psychiatric disorders (PD) have been highlighted, a link between PD and acute aortic dissection (AAD) has not been shown. Aim of this study was to define the psychological profile of patients treated for AAD and analyze the impact of PD postoperatively and at 5-year follow-up period. Methods: Two-hundred and twelve patients underwent surgery for AAD during a 9-year period, and operative mortality was 26% (n = 55/212). Of 157 survived patients, 53 (34%) (mean age 59 ± 13 years; 40 males- 75.5%), underwent psychiatric consultation postoperatively. Ascending aorta +/- arch replacement was performed in 37 patients, Bentall +/- arch replacement in 16. Data were retrospectively analyzed. Mean duration of follow-up was 32 ± 25 months. Results: In 31 patients psychiatric changes were present in their medical history. Postoperatively in 25 of them a definitive diagnosis of PD (Group PD) was made in agreement of DSM-IV criteria as: major depression (n = 10), anxious-depressive syndrome (n = 5), bipolar disorder type 2 (n = 5), panic attacks (n = 2), paranoid schizophrenia (n = 1), anxiety (n = 2). Patients without a definitive psychiatric diagnosis were classified as Group non-PD (n = 28). In the postoperative period clinical manifestations of PD including delirium, persistent spatiotemporal disorientation, psychomotor agitation were evident in 20 patients (80%) in Group PD vs. 4 patients (14.8%) in Group non-PD (P < .0001). During follow-up neither deaths nor suicide attempts occurred; only 6 patients of Group PD required PD treatment (P < .0001 vs. early postoperative findings); 2 patients in Group non-PD required psychiatric medical treatment. Conclusion: Our findings suggest that the incidence of postoperative psychiatric complications is higher in patients affected by preoperative PD. During follow-up freedom from PD is lower in patients who experienced postoperative PD-related complications. Since the psychiatric conditions appeared to be comfortably stable during follow-up, treatment of AAD for patients affected by PD seemed to represent the first step to detect their psychiatric disorder and to start correct medical therapy.
Genetic Association Analysis and Selection Indices for Yield Attributing Traits in Available Chilli ( Capsicum annuum L.) Genotypes

The present investigation was conducted with 30 chilli genotypes at the experimental field of Regional Spices Research Centre, BARI, Gazipur to assess the genetic association and selection indices among yield and important yield attributing traits. Fruit length, fruit weight, 100 seed weight and fruits/plant showed significant and positive correlation with yield/plant both at genotypic and phenotypic level. Path coefficient analysis revealed that fruits/plant had maximum positive direct effect on yield. Besides fruits/plant; fruit weight, fruit length and number of primary branches/plant also contributed positive direct effect to yield. Selection indices were constructed through the discriminate functions using five characters. Highest relative efficiency was found for fruit weight +fruits/plant +yield/plant comparable to other combinations of characters. This research indicated that the selection of high yielding chilli genotypes based on these three characters might be more efficient. Biplot analysis was also performed to find out superior genotypes.
Factors Influencing Meat Buying Behaviour among Rural , Semi-Urban and Urban Households

The worldwide meat consumption has attracted much attention not only for nutritionists but also agricultural and food economists in recent years. Studies showed that urbanization has been carrying a rise in demand for meat products. In India, cultural differences are also accountable for variations in meat consumption patterns. A study was performed to ascertain the preferences of consumers towards meat consumption among the rural, semi-urban and urban households of Karnataka with sample size of 90 meat eating respondents and 30 non-meat eating respondents. The results showed that ‘flavour’ and ‘taste’ of the meat had a very good influence on meat consumption among all the locations.
Responsible estuarine finfish stock enhancement: an Australian perspective

The responsible approach to marine stock enhancement is a set of principles aimed at maximising the success and benefits of artificially re-stocking depleted fisheries. The benefits of such an approach are evident in the 400% increase in survival of stocked striped mullet in Hawaii through refinement of release techniques, however financially or temporally constrained stocking programs in Australia have not adhered to all principles. A pragmatic approach to address these principles is proposed, using international examples and Australian marine finfish pilot stockings of barramundi, mulloway, sand whiting, dusky flathead and black bream. Biological ranking of candidate species by estuarine residency, a low natural-mortality to growth ratio, a large L∞ and comparison by recreational value and available rearing technologies, show that mulloway, barramundi and sea mullet are ideal species for stocking in Australia. Australian intermittently closed opening landlocked lagoons and recreational fishing havens, especially near cities, provide experimental opportunities to apply this approach and stock suitable species through small-scale pilot experiments. This would allow evaluation of production and carrying capacity, and density dependent processes with respect to optimal stocking strategies unconfounded by emigration and commercial fishing practices. Twenty per cent of Australians fish each year, and harvest approximately 27 000 t of finfish. Stocking recreationally important species in Australia should give a greater financial benefit, which is spread across a larger cross-section of the community, compared to stocking to enhance commercial fisheries. The pragmatic application of the responsible approach, and stocking of fast growing estuarine residents into recreational fishing havens would enhance the benefit from marine stocking.
Ba-rich adularia from the Ouachita Mountains, Arkansas: Implications for a postcollisional hydrothermal system

Jet-black Ba-rich adularia occurs as twinned, euhedral crystals within the Womble Shale (Lower Ordovician) on the shore of Lake Ouachita, Arkansas, in the area of the Benton uplift. The adularia crystals are localized along organic-rich seams in silty micrite, in intimate association with postfolding quartz veinlets. They display two distinct habits. Earlier adularia of the Felsdbanya habit are Ba zoned with typical core compositions near Ite.r6qBqo. rsoy{11r. ,u,1Si1, ,oqO, and edges near Ilo rroBqo.oroy{llr orn;Si1, nssyOs. Later, blocky adularia crystals are not Ba zoned and have compositions similar to those in the edges of crystals with the earlier habit. X-ray diffraction analysis indicates that both adularia habits are dominantly monoclinic with a low degree of triclinicity. K-Ar analysis yields a date of 262 + l0 Ma, consistent with a Permian age for adularia mineralization. Fluid-inclusion 6[1a srrggest that adularia was deposited from a hydrothermal fluid with a salinity of 3 wto/o NaCl equivalent at a maximum temperature of 300{ and a maximum p;essure of 1.9 kbar. This pressure corresponds to a maximum lithostatic depthof 7.6 km, considerably less than that postulated for rocks overlying the Womble Shale (> 15 km). The age, composition, and depth of formation of the Ba-rich adularia place severe constraints on the postcollisional evolution of the Ouachita Mountains and may suggest a genetic tie to the formation of Mississippi Valley-type Pb-7-n-Ba deposits. INrnooucrroN Jet-black, Ba-rich adularia occurs as twinned, euhedral crystals within thinly bedded micrite of the lowest member of the Womble Shale (Lower Ordovician), in outcrop on the shore of Lake Ouachita, Arkansas, in the area of the Benton uplift. The Womble Shale is a black, carbonaceous, graptolitic, illitic shale, intercalated with silty micrite, silty sandstone, and phosphatic conglomerate beds (Sterling et al., 1966). The adularia crystals appear to be localized along organic-rich seams in the micrite, frequently in intimate association with postfolding quartz veinlets. Adularia is frequently the only mineral that can be used to date events within the Ouachita Mountains. Thus, detailed geochemical studies were undertaken to determine the composition and age of the adularia, and their relationship to the structural evolution of the Ouachita Mountains. AouI,. cnrA.

Land Cover Classification from Satellite Imagery with U-Net and Lovász-Softmax Loss

The land cover classification task of the DeepGlobe Challenge presents significant obstacles even to state of the art segmentation models due to a small amount of data, incomplete and sometimes incorrect labeling, and highly imbalanced classes. In this work, we show an approach based on the U-Net architecture with the Lov´asz-Softmax loss that successfully alleviates these problems; we compare several different convolutional architectures for U-Net encoders.
Stability condition for discrete systems with multiple state delays

many natural systems have intrinsic delays, caused by input, output or state variables. In an open-loop system, input delay doesn't affect the stability but if feedback of the state is utilized for controlling the systems, the delay is transferred to closed-loop state and would affect the stability of the system. It is important to evaluate/examine the stability of continuous and discrete delayed-systems. In continuous systems existence of delay increases system dimension to infinity (number of poles is infinite). In discrete systems, number of poles increases but it is finite. Due to the lack of proper and powerful tools in discrete systems, the evaluations of stability in these systems are very important. In this paper, an approach has been proposed based on Lyapunov equation and frequency domain stability analysis for systems which have delay in their states. In this approach, stability conditions have been obtained for discrete systems with delay in a specific interval. All previous works on discrete systems are often for single-delay in state. The purpose of this paper is to extend the existence approaches for systems that have multiple delays in their states. Performance of the proposed method has been studied in several examples.
Economic impacts of cassava research and extension in Malawi and Zambia

This paper estimates the economic impacts of cassava research and extension in Malawi and Zambia over the period 1990-2008. The data come from sample household surveys, planting material production records, and a series of cassava improvement experiments conducted in the two countries. Past investments in cassava improvement have led to the development and release of a good number of high-yielding and cassava mosaic virus disease (CMD)-tolerant cassava varieties. The results show relatively higher adoption rates for the CMD-free local varieties compared to CMD-tolerant varieties that have been released in the two countries. The adoption of new varieties has been low and slow largely due to the fact that most of these varieties lacked the consumption attributes highly valued by farmers. The multiplication and distribution of CMD-free planting materials of the recommended local varieties led to greater adoption, but infection with CMD three to four years after adoption meant that the yield gains and economic benefits could not be sustained. Nevertheless, the multiplication and distribution of clean cassava planting materials generated a modest rate of return of 24%, which is actually consistent with an earlier rate of return estimate of 9 to 22% for cassava improvement in developing countries. Analysis of the ex ante impacts of current and future investments in cassava improvement shows that cassava improvement research that focuses on the development and dissemination of varieties with highly preferred consumption and industrial attributes would yield a greater rate of return of 40%.
On the coefficient problem for bounded univalent functions

In this paper we shall develop a technique for estimating the coefficients bv (v > 1) of the power series (1) of the class S(bj) which is particularly efficient in the case where b1 is close to' 1. The method is based on a generalization of an inequality, due to Nehari, which represents a necessary and sufficient condition for a function (1) to belong to the class S(bl) [4], [10]. Nehari's inequality is a counterpart of Grunsky's necessary and sufficient condition for an analytic function to be univalent [2]. It is of methodological interest to derive the generalized Nehari inequality in a manner which shows its close relation to the original Grunsky inequality. We will prove it in two different ways. In ? 2 we will establish it by the variational method, while in ? 3 we shall obtain it by the Grunsky method, using Faber polynomials and their generalizations. In ? 4 the results proved will then be applied to the coefficient problem for the class S(b,). We shall treat, in particular, the cases of the coefficients bv with v = 3 and 5. The extension of the considerations for higher indices can be achieved by analogous arguments. To define the terms of our inequality, consider the power series
Momentum Profits in Australian Listed Property Trusts

Abstract This paper examines the profitability of momentum trading strategies in Australian listed property trusts (LPTs). Monthly value-weighted momentum portfolios are formed using the monthly excess returns of LPTs for the period from 1990 to 2005. Overall the findings confirm that a momentum trading strategy in Australian LPTs is a profitable strategy. More specifically, momentum strategies are profitable after adjusting for variance and downside risk where the momentum returns substantially outperform the benchmark. An analysis using different study periods confirm the findings about momentum. The practical implication from this study is that investors can generate substantial abnormal returns by adopting a momentum trading strategy, particularly with a long strategy (i.e. winner portfolios).
Micronekton diel migration , community composition and trophic position within two biogeochemical provinces of the South West Indian Ocean : Insight from acoustics and stable isotopes

Spatial distribution, community composition and trophic roles of micronekton (crustaceans, fishes and squids) were investigated in the Indian South Subtropical Gyre (ISSG) province and the East African Coastal province (EAFR), by combining acoustic surveys, mid-water trawls and stable isotope analyses from scientific cruises conducted in 2009 and 2010. Mesopelagic micronekton performed diel vertical migrations in both provinces, from deep (400–740m) to surface (0–200m) layers at dusk and in the opposite direction at dawn, with some species migrating below 740m. The EAFR province was more dynamic than the oligotrophic ISSG province, with enhanced eddy activity and enhanced yearly productivity. The active enrichment mechanisms in the EAFR, in terms of available primary production, led to high micronekton acoustic density (as a proxy of micronekton abundance) and large micronekton weight and abundance estimates from trawl data. Particulate organic matter in the EAFR exhibited greater enrichment in C and N compared to the ISSG and, consequently, tissues of selected micronekton organisms in the EAFR were more enriched in N (higher δN values). In both provinces, micronekton encompassed a wide range of isotopic niches, with large overlaps between species. Micronekton and swordfish in the EAFR had an overlapping range of δN values, contrasting with the ISSG province where swordfish were two trophic levels higher than the sampled micronekton. Our results provide some evidence that the combined action of riverine input and the dynamics of eddies might influence productivity in the EAFR, and hence the abundance of micronekton and the enrichment of tissues in N, compared to the oligotrophic ISSG
Ciprofloxacin residues in chicken and turkey carcasses

Ciprofloxacin residues were detected in chicken and turkey tissues "thigh, breast, liver and kidney" by using HPLC. Results reflected a significant difference variation among kidney, liver, breast and thigh in examined chicken and turkey samples as p values <0.05 indicating that kidney and liver are the site of accumulation of ciprofloxacin residues The highest residual level of ciprofloxacin found in kidney then liver Whereas the lowest concentrations were found in breast then thigh muscles. The means average of ciprofloxacin residues in examined chicken samples in kidney , liver , breast and thigh respectively, were 316+/-26.4 μg/kg , 211.1+/-20.6 μg/kg, 131.7+/-25.2 μg/kg and 92.11+/-30.1 μg/kg ; on the other side the means for turkey samples were 291.9+/-29.9 μg/kg , 205.7+/-23 μg/kg , 119.2+/-12.5 μg/kg and 83.2+/19.6 μg/kg respectively; By Using of different heat treatment processes, Ciprofloxacin residues are heat stable compounds as they couldn’t be degraded by any cooking methods except microwaving at 800 W with one spoonful of sunflower oil for 15-20 minutes for muscles and 3-5 minutes for liver and kidney, Also freezing for 1 month at -20co could degrade ciprofloxacin to its metabolites at levels lower than permissible limits but not to Un detectable levels. key words: Residues -Ciprofloxacin -PoultryTurkeys –HPLC.

Preparation of activated charcoal adsorbent from waste tire

Activated carbons were prepared from waste tire in two different routes. Some physical properties of thus prepared activated carbons were measured and the characterization of their phases was done by XRD measurement. The adsorption isotherms of methylene blue were simulated by the Langmuir and Freundlich isotherms. The Langmuir isotherms were found to have better fitting with Q max values 0.227, 0.255 and 0.256 mmol/g for the activated carbons prepared in air, nitrogen, nitrogen and steam respectively while it was 0.275 mmol/g for activated carbon impregnated with H 3 PO 4 . The overall reaction was found to be pseudo-second order with the rate constant of 8.314 × 10 -4 Lg/(mmolmin). The surface area of the best prepared activated carbon was 334.2 m 2 /g.

Nanobelt and nanosaw structures of II-VI semiconductors

The II-VI semiconductors are important optoelectronic, luminescent, and lasing materials. This paper presents a review on synthesis, structure, and growth mechanisms of one-dimensional nanostructures of ZnS, CdSe, ZnSe, CdS and CdO. The two most frequently received wurtzite structures of these materials are "nanobelts" and "nanosaws". The nanosaws are suggested to be a result of atomic-termination induced asymmetric growth due to the cation-terminated, catalytically active (0001) surface, while the anion-terminated (000 ī) is chemically inactive. It has also been shown that the phase transformation from wurtzite to zinc blend could also be a factor in initiating the growth of the saw teeth. The applications and nanodevices that have been built using nanobelts are also presented.
