Content of minerals in soybean seeds as influenced by farming system, variety and row spacing

Soybean is a important source of protein and fat in the food and animal feed industries. Moreover, soybean also contains many other compounds, including minerals, which are beneficial for health and reduce the risk of many diseases. This study was conducted at the Czesławice Experimental Farm near Lublin (51°18′23′′N, 22°16′02′′E) in 2016. The soil on which the experiment was set up belongs to typical Luvisols. It was characterized by high phosphorus and potassium availability as well as very high magnesium availability. The aim of the present study was to determine the effect of cultivation (organic and conventional system) and row spacing (22.5 cm and 35 cm) on the level of minerals in seeds of two soybean varieties: Aldana and Merlin. The study was conducted using a split-plot design, in three replicates. Seeds were sown on May 5, whereas harvest was carried out on September 5, 2016. After seeds were harvested, the content of the following major minerals was determined in them: phosphorus, potassium, magnesium, calcium, molybdenum, manganese, copper and nickel. Variety Aldana seeds were characterized by a significantly higher content of potassium and copper, while in var. Merlin seeds the calcium concentration was higher. The contents of phosphorus, potassium, calcium, copper and nickel were found to be significantly higher in conventional system grown soybean seeds. Seeds of soybean grown at a row spacing of 22.5 cm contained more copper and nickel. Row spacing was not found to significantly affect the macronutrient content in the studied material.

Acute Oral Toxicity (LD50) of Crude Exopolysaccharide from Rhodotorula minuta BIOTECH 2178 in ICR Mice

Acute toxicity study on lyophilized exopolysaccharide (EPS) produced from Rhodotorula minuta BIOTECH 2178 EPS was evaluated using laboratory mice. In this study, 20 male ICR mice were divided into four (4) groups: Group I received 0.5 ml saline solution; Group II was treated with 50mg EPS/kg body weight; Group III was treated with 225mg EPS/kg body weight; and Group IV was treated with 400 mg EPS/kg body weight. Blood samples were collected via orbital sinus for hematological analysis. Body weight, feed and water consumption were recorded daily. Liver and kidney were collected for histopathological analysis after 15 days administration of EPS. Blood chemistry analysis showed that mice fed with crude EPS had comparable BUN, creatinine and ALT values with that of the control. Liver histopathological analysis of the control and treated group showed normal hepatic architecture with intact hepatic cells, nucleus, sinusoidal spaces and a central vein. Histopathological analysis of the kidney showed normal renal structure of cortex, indicating a normal architecture of renal glomeruli, proximal convoluted tubule and distal convoluted tubules. Moreover, the tubules showed a relatively regular distinct lumen of both control and treated groups. Thus, crude EPS from R. minuta BIOTECH 2178 is neither hepatotoxic nor nephrotoxic and likely to be safe for human consumption. Moreover, its safety property lays a good foundation for application of EPS in food and pharmaceutical industries.

"Yes we can …": Using benefit transfer to inform environmental policy making

Economic analysis can assist these decisions in three main ways to: 1. provide insights into the reasons why an issue (or problem) may exist at all, helping to identify whether an issue can be categorized as a spillover effect (i.e., externality), underprovided public good, market failure and/or government failure; 2. identify whether a problem is worth fixing by applying cost benefit analysis (CBA) to evaluate whether and how society would be advantaged by a policy change; and, 3. evaluate the impacts of alternative potential policy solutions (such as extension, information and suasion methods, regulations, changing property rights, positive and negative incentives, and market based instruments) to effect the change.
ON THE THREE-DIMENSIONAL STRUCTURE OF THE MASS, METALLICITY, AND STAR FORMATION RATE SPACE FOR STAR-FORMING GALAXIES

We demonstrate that the space formed by the star formation rate (SFR), gas-phase metallicity (Z), and stellar mass (M⋆) can be reduced to a plane, as first proposed by Lara-López et al. We study three different approaches to find the best representation of this 3D space, using a principal component analysis (PCA), a regression fit, and binning of the data. The PCA shows that this 3D space can be adequately represented in only two dimensions, i.e., a plane. We find that the plane that minimizes the χ2 for all variables, and hence provides the best representation of the data, corresponds to a regression fit to the stellar mass as a function of SFR and Z, M⋆= f(Z, SFR). We find that the distribution resulting from the median values in bins for our data gives the highest χ2. We also show that the empirical calibrations to the oxygen abundance used to derive the Fundamental Metallicity Relation have important limitations, which contribute to the apparent inconsistencies. The main problem is that these empirical calibrations do not consider the ionization degree of the gas. Furthermore, the use of the N2 index to estimate oxygen abundances cannot be applied for 12 + log(O/H) ≳ 8.8 because of the saturation of the [N ii] λ6584 line in the high-metallicity regime. Finally, we provide an update of the Fundamental Plane derived by Lara-López et al.
INTEGRATED CROSS LAYER OPTIMIZATION APPROACH FOR QUALITY OF SERVICE ENHANCEMENT IN WIRELESS NETWORK

Abstract Wireless network has emerged as the primary technology for the next generations networks and it adopts various feature such as ease of deployment, low cost, increased coverage which forms the selforganized structure without relying on any fixed network. Wireless network possesses various multimedia transmission application such as real time delivery of audio, video and VOIP; out of these services video transmission is considered as more challenging as it requires high QoS as the QoS are degraded often due to unreliable nature of network, fading radio signals, node’s mobility. Moreover, high quality video transmission requires high QoS such as efficient bandwidth utilization, high throughput, low delay and high PSNR value for video transmission; in order to utilize the network resources, guaranteed QoS is essential requirement which has been researched by several researchers, however main issue of these approaches are missing end-to-end QoS guarantee for video transmission. In this paper we design and develop an ICLO (Integrated Cross Layer optimization) approach which aims to enhance the Quality of Service; considering two major issue i.e. video encoding and packet transmission. Further, these problem are solved through various optimization model such as optimization of channel modelling, obstacle aware interference modelling, queueing model and video distortion model. Further these optimization are integrated to solve the designed problem which enhances the Quality of Service. Further, we evaluate the ICLO considering the performance metrics like bandwidth efficiency, PSNR, Throughput and End-to-End delay.
Effects of nitrogen concentrations on nodulation and nitrogenase activity in dual root systems of soybean plants

ABSTRACT Currently, the mechanisms underlying the effects of nitrogen on nodulation and nitrogen fixation of leguminous plants remain uncertain. To further investigate the relationship between nitrogen with nodulation and nitrogen fixation of soybean plants, a young seedling grafting technique was applied to generate soybean plants with dual root systems. The two root systems were separately cultured in sand medium, with one irrigated with nutrient solution containing or as nitrogen sources (the N+ side) and another irrigated with nitrogen-free nutrient solution (the N− side). Various nitrogen concentrations, 0, 25, 50, 75, and 100 mg/L, were applied to the N+-side root system to determine the effects of nitrogen concentrations on nodulation and nitrogenase activity of soybean plants. The results showed that in the dual root systems constructed by seedling grafting, the number and weight of root nodules at the N+ side both exhibited a single-peak changing trend of first increasing and then decreasing with nitrogen concentrations. Root nodulation was accelerated by low concentrations of nitrogen (<50 mg/L) and significantly suppressed by high concentrations of nitrogen (>50 mg/L). In contrast, the number and weight of root nodules at the N− side showed a constant increasing trend with the increase in nitrogen concentrations. Taken together, these results indicated that high nitrogen concentration exerts a contact-dependent localized inhibitory effect on the formation (number of nodules) and growth of root nodules (weight of nodules). The nitrogenase activities in the root nodules at both the N+ and the N− sides displayed trends of first increasing and then decreasing with nitrogen concentrations, reaching a single peak when the nitrogen concentration was 50 mg/L. In addition, the promotive or inhibitory effects of nitrogen at different concentrations on nitrogenase activity in the root nodules were synchronous between the N+ and the N− sides, suggesting that the effect of nitrogen is systematically regulated via interactions between the aboveground and underground parts of the plants.
Patent licensability and life: A study of U.S. patents registered by South Korean public research institutes

The quality and value of a patent can be represented by several proxies, such as how often the patent is cited in other patents, whether it is licensed, and the age of the patent. The paper uses a binary choice model to investigate factors affecting patent licensing, and it uses double-bounded tobit and duration models to investigate factors affecting patent life. Explanatory variables and dependent variables are extracted from U.S. patent information and related data. Findings suggest research collaboration has a positive effect on both patent licensing and patent life. Other characteristics such as invention size, namely, the scope of the invention measured by number of claims, and organizational technological cumulativeness, measured by self-citation counts, also affect patent life.
Study of curcumin antioxidant activities in robust oil–water nanoemulsions

Oil-in-water (o/w) nanoemulsions of peanut, linseed and mustard oils with sodium dodecyl sulphate (SDS), dodecyltrimethylammonium bromide (DTAB), tween 20 (Tw-20) and tween-40 (Tw-40), were prepared for catalysing the antioxidant activity of curcumin. The peanut oil–Tw-20, linseed oil–DTAB and mustard oil–SDS ranging in size from 488.41 to 1337.09 nm, 446.10 to 1124.00 nm and 27.37 to 62.05 nm, have expressed free radical scavenging activities (FRSA) of 72.38 to 93.13 %DPPH, 65.08 to 85.55 %DPPH and 62.15 to 89.44 %DPPH, respectively. Their surface tensions in the range of 41.68–58.77 mN m−1 and viscosities of 0.8051–1.4059 mPa s infer enhanced curcumin dispersion. FTIR stretching frequencies (SF) of 1500–2000 cm−1 (CO) and 3500 cm−1 (–OH) infer curcumin encapsulation with the disappearance of the oil–curcumin SF (500–1300 cm−1). Friccohesity, a distribution indicator exercised via cohesive forces (CFs) and intermolecular forces (IMFs), has depicted curcumin nanodispersion on weakened oil and curcumin CFs.
A pH-responsive and magnetic Fe3O4@silica@MIL-100(Fe)/β-CD nanocomposite as a drug nanocarrier: loading and release study of cephalexin

In the present work, a novel magnetic and pH-responsive porous nanocomposite was prepared by the surface grafting of β-cyclodextrin onto Fe3O4@silica@MIL-100(Fe). The effect of pH and temperature on the adsorption of cephalexin and release behavior of the developed nanocomposite was studied. It was found that the maximum adsorption occurs at room temperature while fast release occurs at higher temperature. Among different two-parameter isotherm models, the results showed that the adsorption of the drug was well described by the Langmuir isotherm model. Different kinetic models including film-transfer, intra-particle diffusion, and pseudo-second order kinetic models were used to investigate the mechanism of adsorption. Thermodynamic studies indicated that the adsorption of cephalexin onto the nanocomposite was exothermic and spontaneous. In addition, the nanocomposite showed sensitive pH-dependent behavior. Finally, mathematical kinetic models such as zero-order, first-order, Korsmeyer-Peppas and Higuchi were studied to investigate the drug release profile where the kinetics of release were well described by the Higuchi model.
The Quantification of Two Grading Elements in Satisfaction based on ServQual Approach by Using IPA and Kano Method: Automotive Industry

This study highlights the integration of the ServQual model, Importance Performance Analysis (IPA), and the Kano method. Service Quality or ServQual is an approach to manage business processes to ensure full satisfaction of the customers and quality of service provided in preceding customer satisfaction. The 5 elements of ServQual are used to develop the survey questionnaire. At the same time, the IPA model is needed to measure service quality, not only the performance of an item but also the importance of the determining factor in satisfaction to the respondent. The Kano method is employed to identify the quality attributes of products or services based on the functional and dysfunctional attributes. In order to know what the customer perceptions and satisfaction levels of the services are, this study involved respondents from the service center of the automotive industry. Through the survey questionnaires and data analysis, the results showed that in Kano, facilities of the service center while in IPA, the security level of service center itself are the major elements that need to be considered. Both of these elements are the improvement needed by the company to look into details to increase and grab more attention towards customer satisfaction.
Towards identifying the active sites on RuO2(110) in catalyzing oxygen evolution

While the surface atomic structure of RuO2 has been well studied in ultra high vacuum, much less is known about the interaction between water and RuO2 in aqueous solution. In this work, in situ surface X-ray scattering measurements combined with density functional theory (DFT) were used to determine the surface structural changes on single-crystal RuO2(110) as a function of potential in acidic electrolyte. The redox peaks at 0.7, 1.1 and 1.4 V vs. reversible hydrogen electrode (RHE) could be attributed to surface transitions associated with the successive deprotonation of –H2O on the coordinatively unsaturated Ru sites (CUS) and hydrogen adsorbed to the bridging oxygen sites. At potentials relevant to the oxygen evolution reaction (OER), an –OO species on the Ru CUS sites was detected, which was stabilized by a neighboring –OH group on the Ru CUS or bridge site. Combining potential-dependent surface structures with their energetics from DFT led to a new OER pathway, where the deprotonation of the –OH group used to stabilize –OO was found to be rate-limiting.
Endothelial vasodilator angiotensin receptors are changing in mice with ageing

Background: The vascular function of Angiotensin II-type-2 receptors in adults is controversial. We sought their location and function in mouse aortic rings at young and old mice. Materials and Methods: Male C57Bl mice (aged 4 and 14 months) were killed by CO2. The descending thoracic aorta was cleaned and dissected into rings. Aortic rings were mounted in Krebs’ solution at 37 °C and then setup in a multi-myograph. Also segments of aorta were incubated with or without antagonists then TMR-Angiotensin II and/or QAPB were added. Results: At 4 months, angiotensin II, at low concentrations, caused losartan-sensitive contraction higher concentrations (100nmol/L) caused relaxation sensitive to endothelial denudation, L-NAME or PD123319. Angiotensin II-type-1 receptors blockade plus L-NAME revealed PD123319-sensitive contraction. At old mice, aortic relaxation to angiotensin II was lost. At young mice, Losartan and PD123319, together but not separately, abolished binding of fluorescent TMR-angiotensin II, to endothelium and smooth muscle, indicatin Angiotensin II-type-1 and Angiotensin II-type-2 receptors in both cell types. In contrast, at 14 months endothelial fluorescence was eliminated by losartan. Conclusion: Aortic endothelium of young adult mice has Angiotensin II-type-2 receptors that release vasodilator nitric oxide. This is lost in old age, explaining age-related loss of vasodilatation by Angiotensin II. Aortic smooth muscle has pro-contractile Angiotensin II-type-1 and Angiotensin II-type-2 receptors in young and old mice. Reciprocal actions of angiotensin II are, due to Angiotensin II-type-1 and Angiotensin II-type-2 receptors situated on different cell types but only at young ages, Angiotensin II-type-1 receptors of unknown function are present on endothelium.
Highly stable n-type thermoelectric materials fabricated via electron doping into inkjet-printed carbon nanotubes using oxygen-abundant simple polymers

Single-walled carbon nanotubes (SWCNTs) are important candidates for flexible and non-toxic thermoelectric (TE) energy-harvesting devices because they have large Seebeck coefficients, good flexibility, and inkjet printability onto plastic substrates. Here we describe the successful n-type conversion of intrinsic p-type SWCNTs by polymer–dopant charge transfer. The negative Seebeck coefficients of the polymer-doped SWCNTs were strongly related to the highest occupied molecular orbital levels of the polymer, demonstrating that the polymers were electron donors for the nanotubes and that the doping level could be controlled by modifying the functional groups. The n-type SWCNTs obtained using oxygen-abundant polymers, such as poly(vinyl alcohol) and poly(vinyl acetate), exhibited the largest negative Seebeck coefficients and high stability under ambient conditions lasting for at least 3 weeks. Printed and folded p- and n-type SWCNTs on flexible substrates showed efficient TE voltage improvements. Our findings enable the easy, low-cost preparation of air-stable n-type SWCNTs, permitting the exploitation of SWCNTs as flexible and eco-friendly TE materials.
Validated HPTLC method for qualitative and quantitative estimation ofoleanolic acid in roots of Cissampelos pareira Linn. var. hirsuta,Menispermaceae

An approach to develop a high performance thin layer chromatography (HPTLC) method in the present study has been made for quantitative estimation of marker compound oleanolic acid in the roots of Cissampelos pareria Linn. var hirsuta (family Menispermaceae). Oleanolic acid was estimated in saponin rich fraction prepared from the powdered roots of C. pareira. Oleanolic acid was separated using silica gel 60 F254 HPTLC plates using toluene: ethyl acetate: formic acid (7:3:0.3, %v/v) as mobile phase. The determination was carried out using densitometric absorbance-reflection mode at 530 nm for oleanolic acid in visible mode. The concentration of oleanolic acid in the saponin rich fraction was found to be 0.1316 % mg/mg. The method was validated in terms of linearity, accuracy, precision and specificity according to ICH guideline.
Massive Pericardial Effusion as the First Manifestation of Hypothyroidism in a Male Patient

This article intends to report a rare case of massive pericardial effusion as the first manifestation of hypothyroidism. A 45-year-old male patient, accompanied by a cardiology department, suddenly started to present signs of dyspnea and tiredness. He was submitted to an echocardiogram and diagnosed with dilated cardiomyopathy associated with a moderate pericardial effusion and low ejection of fraction. The laboratory tests showed elevated TSH levels (13.20 mIU/L), what leads to the hypothyroidism diagnose and enable to start the treatment with levothyroxine. The patient has not followed correctly the treatment, reason why he has not showed any improves. He was admitted in the hospital to cardiology monitoring and the chest radiography confirmed an intense pericardial effusion. Then, the patient was submitted to the pericardiocentesis procedure, which was capable of remove the pericardial fluid for laboratory analysis and fragment of the pericardial sac for neoplastic cell research. After the hospital discharge, he was maintained in outpatient follow-up, when showed an important improvement in the clinical state.

NEW ADD-IN FOR ENGINEERING SIMULATIONS IN SPREADSHEETS USING HOMOTOPY CONTINUATION METHODS

Solving models represented by non-linear equations is a common situation in engineering and can be a challenging task. Homotopy Continuation Methods have shown globally convergent behavior, capable of finding all the possible roots of algebraic systems. Based on these methods, a new Microsoft Office Excel add-in was developed, SphereSolver , aiming to enhance the ability to use this easily obtainable software as a simulation computing platform for engineering problems. SphereSolver was applied over different types of engineering models and the non-linear equations were solved successfully each time. Selected problems were solved with SphereSolver and compared with other solution tecniques, e.g., classical Newton’s method, Fixed Point homotopy or Affine Homotopy. It was observed that using SphereSolver the solution for selected problems was improved, i.e., the interval of convergence is extended massively and/or additional roots can be found. It can be concluded that SphereSolver is a new and efficient tool that can be used within Microsoft Excel for solving engineering problems where other software or traditional tools could fail or present limitations
