A dimeric precursor, [Cu(dmae)(OCOCH3)(H2O)]2 for the CVD of copper metal films, (dmaeH = N,N-dimethylaminoethanol) was synthesized by the reaction of copper(II) acetate monohydrate (Cu(OCOCH3)2H2O) and dmaeH in toluene. The product was characterized by m.p. determination, elemental analysis and X-ray crystallography. Molecular structure of [Cu(dmae)(OCOCH3)(H2O)]2 shows that a dimeric unit [Cu(dmae)(OCOCH3)(H2O)]2 is linked to another through hydrogen bond and it undergoes facile decomposition at 300 C to deposit granular copper metal film under nitrogen atmosphere. The decomposition temperature, thermal behaviour, kinetic parameters, evolved gas pattern of the complex, morphology, and the composition of the film were also investigated.

To find out the responses of soybean genotypes in terms of different levels of irrigation with the aim of evaluating the growth, yield, and its optimum levels of irrigation, an experiment was conducted at the Field of Crop Botany Department, Bangladesh Agricultural University, Mymensingh during the period from November 2000 to February 2001. Five levels of irrigation viz. ~textrmI0 : no irrigation, ~textrmI1 : one time irrigation at 20 days after sowing (DAS), ~textrmI2 :two times irrigation at 20 and 40 DAS, ~textrmI3 : three times irrigation at 20, 40, and 60 DAS, and ~textrmI4 : four times irrigation at 20, 40, 60, and 80 DAS and three genotypes of soybean viz. BS-3, BS-16, and BS-60 were used in this experiment. The crop was grown in a split plot design having three replications. The plant height, leaf area index, crop growth rate, shoot dry weight, branches ~textrmplantI-1 , filled pods ~textrmplantI-1 , seeds ~textrmplantI-1 , seed yield, and harvest index were influenced significantly by irrigation and these were found to be highest at three times irrigation except branches ~textrmplantI-1 . The chlorophyll content increased but empty pods ~textrmplantI-1 decreased with increase in irrigation levels. Genotypes of soybean varied significantly in terms of growth attributes at various growth stages except shoot dry weight at 90 DAS. The genotype BS-3 performed better compared to other genotypes and gave maximum seed yield.

Rabbani M. G.,Solaiman A. R. M.,Hossain K. M.,Hossain T. The Korean Society of Crop Science 2005 Korean journal of crop science Vol.50 No.2

The effects of Rhizobium inoculant, nitrogen, phosphorus, and molybdenum on nodulation, dry matter production, yield attributes, pod and seed yields, protein and phosphorus contents in seed of pea (pisum sativum) var. IPSA Motorshuti-3 were assessed by a field experiment. Among the treatments Rhizobium inoculant in combination with 25kg P and 1.5kg Mo/ha performed best in recording number of nodules/plant, total dry matter yield, number of pods/plant, number of seeds/pod, 1000-seed weight, green pod yield, green and mature seed yields of pea. The highest green pod yield of 15.37 t/ha ($97.05\%$ increase over control) and green seed yield of 9.6t/ha ($69.31\%$ increase over control) were obtained by inoculating pea with Rhizobium inoculant in association with 25kg P and 1.5 Mo/ha. The effects of 60 or 120kg N/ha were comparable to Rhizobium inoculant in most cases. There were positive correlations among yield attributes, yield, protein and phosphorus contents in seeds of pea. From the viewpoint of yield attributes, yield, and seed quality, application of Rhizobium inoculant along with 25kg P and 1.5kg Mo/ha was considered to be the balanced combination of nutrients for achieving the maximum output from cultivation of pea in Shallow-Red Brown Terrace Soil of Bangladesh.

Erucic acid (EA) is one of the key fatty acids usually found in canola oil, mustard oil and rapeseed oil. Consumption of EA in primates was found to cause myocardial lipidosis and cardiac steatosis. To have an insight of the effect of EA in humans, we performed in vitro interaction studies of EA with the primary plasma protein, human serum albumin (HSA). Spectroscopic (UV-vis and fluorescence) analysis of the HSA-EA interaction revealed a static mode of quenching with binding constant K<SUB>b</SUB> ~10<SUP>4</SUP> reflecting high affinity of EA for HSA. The negative value of ΔG<SUP>o</SUP> for binding of EA to HSA in the fluorescence studies indicates the process to be spontaneous. Thermodynamic signatures of the HSA-EA interaction in the complex reflect dominance of hydrogen bonds. Despite predominance of hydrogen bonds, hydrophobic interactions in the HSA-EA complex were found acting as a contributing factor in the binding of EA to HSA, observed as structural change in the far-UV CD spectra. Forster's resonance energy transfer of the EA-HSA complex revealed a distance of 3.2nm between acceptor molecules (EA) and the donor Trp residue of HSA. To have a deeper insight of the structural dependence of the HSA-EA interaction in the complex, thermodynamic study was supplemented with molecular docking. The molecular docking analysis further highlighted the EA binding in the subdomain IIIA (Sudlow site II) of HSA. The information generated in the study reflects greater pharmacological significance of EA and highlights its importance in the clinical medicine.

Modeling Differential Global Positioning System Pseudorange Correction

This paper focuses on modeling and predicting differential GPS corrections transmitted by marine radio-beacon systems using artificial neural networks. Various neural network structures with various training algorithms were examined, including Linear, Radial Biases, and Feedforward. Matlab Neural Network toolbox is used for this purpose. Data sets used in building the model are the transmitted pseudorange corrections and broadcast navigation message. Model design is passed through several stages, namely data collection, preprocessing, model building, and finally model validation. It is found that feedforward neural network with automated regularization is the most suitable for our data. In training the neural network, different approaches are used to take advantage of the pseudorange corrections history while taking into account the required time for prediction and storage limitations. Three data structures are considered in training the neural network, namely all round, compound, and average. Of the various data structures examined, it is found that the average data structure is the most suitable. It is shown that the developed model is capable of predicting the differential correction with an accuracy level comparable to that of beacon-transmitted real-time DGPS correction.

Dyeing of electrospun nylon 6 nanofibers with reactive dyes using electron beam irradiation

Park, M.,Rabbani, M.M.,Shin, H.K.,Park, S.J.,Kim, H.Y. THE KOREAN SOCIETY OF INDUSTRIAL AND ENGINEERING 2016 JOURNAL OF INDUSTRIAL AND ENGINEERING CHEMISTRY -S Vol.39 No.-

<P>Nylon 6 nanofibers were prepared by using an electrospinning technique. The dyeing behavior of nylon 6 nanofibers which were dyed with reactive dyes, vinylsulphone type-Remazol Red RR, by electron beam irradiation (EBI) has been investigated. Electrospun nylon 6 nanofibers were irradiated varying EBI doses of 10, 20, 30, 40, 50, 100 kGy and their K/S values, Lab values and dyeing equilibrium were observed. No additives and toxic reagents were used for dyeing nylon 6 nanofibers with reactive dyes using radiation. Compared with conventional dyeing method, it is found that irradiated dyeing of nylon 6 nanofibers with reactive dyes has improved not only the color strength and fiber-shrink phenomenon but also the scission reactions of functional groups of Remazol Red RR at EBI dose greater than 10 kGy. This finding suggests that the dyeing by EBI significantly influence the waste-water treatment in a green way. The resulting dyed nylon 6 nanofibers were characterized using scanning electron microscopy (SEM) and UV-Visible spectroscopy.
