Water assisted atmospheric CVD super growth of vertically aligned CNT forest for supercapacitor application

We report a high growth rate (37 μm/min) synthesis of vertically aligned carbon nanotube (VACNT) forest, achieving remarkable height exceeding a millimetre with good crystallinity. VACNTs with few numbers of walls have been grown over Fe–Co/Al2O3/SiO2 coated Si wafer using the water assisted atmospheric pressure chemical vapour deposition (WACVD) method. The key to this success lies in the synergistic combination of a bimetallic catalyst (Fe-Co) with buffer Al2O3 layer and the WACVD method. Notably, the VACNT forest, synthesised at optimized conditions can be directly used without the need for additional post-growth purification processes, eliminating the risk of potential damage to the CNTs. Finally, the VACNT forest exhibits excellent areal capacitance of 133.33 mF/cm2 at a current density of 1 mA/cm2 with outstanding cyclic stability of 130 % @ 3000 cycles.

Analysis of super Cr13 stainless-steel internal fracture growth effects during skew mill piercing process

The seamless tube piercing process of super Cr13 martensitic stainless steel is addressed in this paper by comparing industrial piercing tests, laboratory hot tensile tests for material behavior characterization, and finite element simulations. Particular focus is given to the effect of process parameters on internal fracture growth and geometrical homogeneity of the tube. The geometrical non-homogeneities found on industrial pierced tubes are closely related to the change of flow stress of super Cr13 stainless steel during the piercing process. This way, the non-uniform strain rate along the tube's cross-section during piercing affects the fracture growth and, consequently, the thickness homogeneity of the tube, which varies from tip to tail. Due to obtained results, the mean value of pierced tube perimeter is 660 mm, while the mean value of the tube perimeter in the FEM simulation was predicted to be 2 % more (675 mm). The contact temperature of the plug and piercing tube was predicted at 1100 °C, and the mean value of pierced tube diameter in the simulation (210 mm) was 1.5 % more than the mean value of the actual tube (207 mm). The morphology of δ-ferrite affects the origin of primary crack initiation during the piercing process. Short and thick grains of δ-ferrite created at low strain rates that lengthen with increasing strain rate affect fracture sensitivity at the tip of the plug, favoring the non-homogeneity of the material.

Physiological quality of soybean seeds produced under different spatial arrangements of plants

The present study aimed to evaluate the physiological effect of seeds on soybean genotypes in the southern region of Rio Grande do Sul. The test was developed in the field, in two agricultural crops, on a farm located in the District of Monte Bonito - Pelotas (RS, Brazil), in eutrophic haplic planosol soil, with geographic coordinates 31° 40' 27"S and 52°23' 28 "W. The experiment consisted of twelve treatments involving two factors: factor A - 3 soybean genotypes (NA 5909 RR (super early, growth indeterminate and maturation group A), NS 6006 IPRO (high grain weight, growth indeterminate and maturation group B 5.9), and NS 5959 IPRO (precocity, indeterminate growth and maturation group C) and factor B - 4 line spacing (0.17; 0.30; 0.45 and 0.60 meters). The experimental design used was randomized blocks in a factorial scheme (3x4) with four blocks. The plant population used was 330.000 plants ha-1. The evaluations of the physiological performance of seeds were germination, first germination count, length and dry matter of aerial part, root, and a total of seedlings, accelerated aging, and emergence in the field. Soybean plants better distributed in the cultivation area, in spacings of 0.17 and 0.30 meters, present greater plant height, stem diameter, and productive performance.the only genotype that presented a reduction in germination as the row spacing increased was 'NS 6006 IPRO', resulting in seeds with lower germination in the spacings of 0.45 and 0.60 m compared to the other genotypes under study. The reduction in the spacings, 0.17 and 0.30 meters, produced seeds with better physiological quality, evidenced in years with rain preceding the harvest.

PRIMITIVE SEGMENTATION OF DOUGONG COMPONENTS BASED ON REGIONAL CLUSTERING

Abstract. As one of the most characteristic components of ancient Chinese architecture, Dougong has an important significance in the history of ancient Chinese architecture, but with the passage of time, wooden building components are prone to decay and missing, so it is particularly important to digitally retain the Dougong. In order to realize the Dougong component segmentation, this paper proposes a super voxel-based Dougong component primitive segmentation method, which is divided into two parts: firstly, super voxelizing the Dougong point cloud data, and secondly, realizing the Dougong component primitive segmentation by using multi-geometric constrained region growth algorithm. In order to verify the effectiveness of the method, this paper selects three main Dougong types of the Qing Dynasty, including pingshenke, jiaoke, zhutouke, for experimental validation, and the results show that the combination of super voxel and regional growth algorithm can effectively extract the geometric primitive surface of the Dougong components with high extraction efficiency and good adaptability, which can be prepared for the subsequent knowledge of Dougong construction method to achieve component segmentation.

The productive performance of soybean genotypes depends on the distribution of plants in the field

This study aims to evaluate the effect of the distribution of plants in the field on the productive performance of soybean genotypes. The test was developed in the field, in two agricultural crops, on a farm located in the District of Monte Bonito - Pelotas (RS, Brazil), in eutrophic haplic planosol soil, with geographic coordinates 31° 40' 27"S and 52°23' 28 "W. The experiment consisted of twelve treatments involving two factors: factor A - 3 soybean genotypes (NA 5909 RR (super early, growth indeterminate and maturation group A), NS 6006 IPRO (high grain weight, growth indeterminate and maturation group B 5.9), and NS 5959 IPRO (precocity, indeterminate growth and maturation group C) and factor B - 4 line spacing (0.17; 0.30; 0.45 and 0.60 meters). The experimental design used was randomized blocks in a factorial scheme (3x4) with four blocks. The plant population used was 330.000 plants ha-1. Five random plants plot, except for grain yield, were evaluated per plot. To evaluate the productive performance the main stem diameter, final plant height, number of branches per plant, number of pods per plant, number of seeds per pod, the weight of a thousand seeds, and yield were measured. Soybean plants better distributed in the cultivation area, in the spacing of 0,17 and 0,30 meters, have higher plant height, stem diameter, and productive performance. The genotypes of soybean performance are influenced by the distribution of plants, and this response depends on the genotype and the production environment

Infinitely Many Sign-Changing Solutions for the Nonlinear Schrödinger-Poisson System with Super 2-linear Growth at Infinity

In this paper, we investigate the sign-changing solutions to the following Schrödinger-Poisson system $$\begin{aligned} \qquad \left\{ \begin{array}{ll} -\Delta u+V(x)u+\lambda \phi (x) u =f(u),\ \ \ &{}\ x \in {\mathbb {R}}^{3},\\ -\Delta \phi =u^2, \ \ \ &{}\ x \in {\mathbb {R}}^{3}, \\ \end{array} \right. \end{aligned}$$ where $$\lambda >0$$ is a parameter and f is super 2-linear at infinity. By using the method of invariant sets of descending flow and a multiple critical points theorem, we prove that this system possesses infinitely many sign-changing solutions for any $$\lambda >0$$ .

Drug super spender tsunami: An integrated medical and pharmacy benefits assessment.

BACKGROUND: As new rare-disease drug therapy, gene therapies, and high-priced cancer drugs receive US Food and Drug Administration approval, there is an increasing potential for drug super spender individuals with more than $250,000 annual drug cost. OBJECTIVE: To categorize all members in a large, commercially insured population by their total annual combined drug costs from both medical and pharmacy benefits and to determine the trend in drug super spender prevalence. METHODS: Using a commercially insured population with integrated medical and pharmacy benefits, all unique members with any enrollment between January 2016 and December 2019 were identified. The sum of total cost for all pharmacy claims plus all medical benefit claim lines for drugs was determined for each member, for each calendar year. Cost was defined as the plan plus member liability at network-discounted price, with no further adjustment for any coupons or rebates. Descriptive statistics were used to describe the drug super spender growth. RESULTS: There was an average of 17.9 million members per year with at least 1 month of eligibility through the 4-year study period. In 2016, a total of 2,994 members with more than $250,000 drug cost per member accounted for $1,324 million drug spend. In 2019, there were 5,894 super spender members (97% increase), accounting for $2,579 million drug cost (95% increase), which was 9.6% of $26,618 million total drug spend. CONCLUSIONS: In this large, commercially insured population, a small (32 per 100,000) number of drug super spender members comprise a disproportionate portion of the total drug expenditures, at $1 of every $10 dollars of total drug expenditures. Health plans need to understand the drug super spender trend and develop strategies to maintain health care affordability. DISCLOSURES: This study was funded internally by Prime Therapeutics LLC. Drs Starner and Gleason are employees of Prime Therapeutics LLC, a pharmacy benefits management company. Dr Bowen is a former employee of Prime Therapeutics LLC.

Super Liquid-repellent Surfaces and 3D Spheroids Growth.

Substrates composition and surface features of materials rule adhesion control of cells to surfaces. As a result, most of the aspects of cell functions, such as spreading, migration, proliferation, and differentiation, can be significantly influenced in biomedical applications. Cell cultures make possible to understand cell biology, tissue morphology, mechanisms of diseases, drug action, and tissue engineering development, among others. Recent techniques related to culturing 3D cell aggregates in the presence of very low wettable surfaces represent an innovative field for in vitro experimentation aimed at more reliable conditions to investigate both tumor and non-tumor cell lines. Matching in particular cell biology to innovative materials, this work reviews the recent literature available on promoting cell aggregates formation strongly influenced by the high surface hydrophobicity. In particular, for spheroid formation, the highest water repellent coatings seem to be required for the significant effectiveness of the process. In this way, 3D cell culture has become a reliable method for reproducing in vitro cellular growth in more realistic physiological conditions.

Highly-porous Super-Growth carbon nanotube sheet cathode develops high-power Lithium-Air Batteries

Lithium-Air Battery (LAB) is expected to develop ultra-high energy density batteries, but the low rate performance and poor cycle life of present LAB cells hinder practical development. Here we report that a highly porous carbon nanotube (CNT) cathode dramatically enhances the rate capability of LAB. Single-walled CNTs (SWCNTs) with wavy patterns prepared from the Super-Growth (SG) method successfully provided CNT sheets with high porosity of up to 94%. The pore structure was characterized by two distinct pores in size, namely, highly extended mesoscale (approximately 5–200 nm) pores formed inside CNT bundles that provide large surface area for oxygen reduction reaction (ORR) and inter-bundle gaps in a micrometer scale that works for oxygen diffusion path. This porous CNT sheet cathode significantly increased the discharge rate of LAB cells, specifically enabling a high discharge current density of 3.0 mA/cm2 securing practical cell capacity of 3.3 mAh/cm2, which is comparable to the current LiB technology that provides ∼3 mAh/cm2 cell capacity at ∼1C rate (∼3 mA/cm2) discharge. Furthermore, this highly porous cathode was also effective for extending the cycle life of LAB cells. Such bimodal pore architecture of the CNT sheet cathode paves the new strategy for developing high-power energy-dense LAB.

Media Tanam Kultur Jaringan yang Tepat untuk Perbanyakan Tanaman Pisang Cavendish (Musa acuminata L.)

There are many types of media used in tissue culture, one of which is Murashige and Skoog (MS). Growth regulators commonly used in tissue culture include Indol Acetic Acid (IAA), Naphthalene Acetic Acid (NAA), Benzyl Amino Purine (BAP), and Indole 3-Butyric Acid (IBA). The aim was to examine the effect of various types of media treatment on the growth of Cavendish banana plants. This research method was carried out by reviewing relevant articles using google until mid-2020. Based on the results of the discussion, it was shown that the most appropriate media for the process of propagation of the Cavendish banana plant was media combined with BAP and IAA hormones, because the concentrations of BAP and IAA hormones could be used. Spur the process of organogenesis in banana plantlets. In addition, giving Super Growth foliar fertilizer 1 ml / l can also stimulate root growth at the rooting stage, so that giving Super Growth is sufficient to induce the formation of shoots and plant roots. Giving coconut water concentration of 7.5% and 15% into the planting medium can produce the best shoot initiation and the number of banana shoots.

Effects of rhizosphere soil nitrification on the compensatory growth of Italian ryegrass (Lolium multiflorum Lam) based on root‐produced cytokinin

AbstractCompensatory growth of forage grass can determine its optimal biomass, which is beneficial for increasing its production. The effect of rhizosphere soil nitrification on Italian ryegrass (Lolium multiflorum Lam) regrowth was investigated on the basis of root‐produced cytokinin concentration in leaves to reveal the forage grass compensatory growth mechanism. The nitrification inhibitor 3,4‐dimethylpyrazole phosphate was added to inhibit soil nitrification. Without soil nitrification being inhibited, compared with no clipping one defoliation cycle increased the leaf photosynthetic rate by 43.82%–53.79%, increased the leaf cytokinin content by 33.48%–34.73%, and increased the cytokinin transport from roots to leaves by 28.88%–39.47%. Nitrification inhibitor decreased soil nitrification rates by 23.33%–84.17% in the rhizosphere and by 42.71%–68.29% in the bulk soil during regrowth. In the rhizosphere micro‐environment, nitrification increased soil nitrate concentration that played an important role in the transport of cytokinin from roots to leaves during regrowth, increasing the leaf cytokinin concentration. However, bulk soil nitrification rate and nitrate content had little influence on leaf cytokinin concentration during regrowth. An increase in leaf cytokinin improved the photosynthesis and the regrowth. Without soil nitrification being inhibited, total biomass at the end of regrowth period was 1.09 times higher in plants that were defoliated once than in non‐clipped plants. However, soil nitrification inhibitor and two defoliation cycles decreased Italian ryegrass regrowth. Super compensatory growth occurred in the one defoliation cycle Italian ryegrasses without adding soil nitrification inhibitor. Compensatory growth occurred in once‐defoliated Italian ryegrass with adding soil nitrification inhibitor and in twice‐defoliated Italian ryegrass without adding soil nitrification inhibitor. In conclusion, rhizosphere soil nitrification is the key factor that regulates the compensatory growth of Italian ryegrass.

Combination of nanoparticles and carbon nanotubes for organic hybrid thermoelectrics

Abstract Carbon nanotubes (CNTs) are usually very expensive, but inexpensive CNTs have been mass-produced by a super-growth (SG) method. The SG-CNTs, however, have many defects resulting in a low conductivity, which is a disadvantage of the SG-CNTs. We discovered that even the defective SG-CNTs can provide a good thermoelectric performance by forming ternary hybrid films made of the SG-CNTs, nanoparticles (NPs) of a conducting polymer complex, poly(nickel 1,1,2,2-ethenetetrathiolate) (PETT) and poly(vinyl chloride) (PVC). The good thermoelectric performance of the ternary film (PETT-NP/SG-CNT/PVC) was possibly attributed to the defect repair effect in addition to the bridging effect of the PETT-NPs among the CNTs. In order to confirm this new concept, we attempted the deposition of metal NPs at the defects of the SG-CNTs. We initially made a physical mixture of palladium (Pd) NPs and the SG-CNTs in dispersions to cover the SG-CNT defects with the Pd-NPs. The obtained films showed only a slight improvement in electrical conductivity. Chemical reduction of the Pd ions in the dispersion of the SG-CNTs, on the other hand, provided hybrids with an enhanced electrical conductivity, thus, use as thermoelectric materials. The thermoelectric figure-of-merit was estimated to be ∼0.3, which is a relatively high value for organic hybrid materials.

Validation of Selection Techniques of Mutual Fund Schemes In India

Investment is necessary for saving and mutual fund can be treated as a vehicle of investment which is liked by all the ages of investors who want to take a ride on it. For doing so, they contribute in this vehicle depending on their risk and return appetite. The fund are invested in the vehicle is driven, controlled and managed by a fund manager. This investment fund uses capital market, money market and debt market to park its funds and get a return on the same. This investment opportunity is best suited for the investor’s class who wants a more diversified investment portfolio. In the modern times mutual fund is a big industry in which many private players are coming and trying to capture the growth. There are many schemes launched by the private players which are creating super normal growth for its investors. The various options in the mutual funds schemes have increased their acceptance to a large investor base. Therefore it is imperative to identify and select those schemes of mutual fund which are best in the lot and can offer better returns to the investors. This research paper has put an effort on validating the selection techniques of mutual fund in India on the basis of return and risk frontier. Paper discussed the basis of selection of all mutual fund schemes based upon highest net asset and ranking. The ranking of these mutual fund schemes are validated by calculating the monthly returns of the funds. Researchers considered data from different sources like yahoo finance, value research online, RBI, NSE etc for this study. After this study, researchers will try to help the investors to identify and select the mutual fund schemes carefully in their portfolio as all the mutual fund schemes even if they are on higher ranking may not perform well in the short run. This will help the investors in maximizing their returns.

Development of life cycle assessment of an emerging technology at research and development stage: A case study on single-wall carbon nanotube produced by super growth method

The frontier of lifecycle assessment (LCA) case studies has moved from understanding conventional technologies to analyzing emerging technologies at the research and development (R&D) phase. One new challenge in LCA that aims to deal with this phenomenon is the development of methods to estimate the environmental impacts of emerging technologies in the R&D phase while considering manufacturing at scale. This study proposes a simple and feasible method that allows LCA practitioners to consider scaling effects of energy consumption during production in a case study of the super growth method of producing carbon nanotubes. In this case, the greenhouse gas (GHG) impact of producing 1 kg of carbon nanotubes decreases from 47.05 t-CO2eq to 21.33 t-CO2eq by scaling up the process. Although the total GHG impacts at the commercial scale estimated from the lab scale inventory are similar to those estimated from the pilot scale inventory, the share of GHG emissions of materials are different because of a change in substrate and a change from batch processing to continuous processing. Carbon nanotube production by the super growth method is competitive with those made by other processes from the viewpoint of GHG impact and product quality.

Mass Equidistribution for Random Polynomials

The purpose of this note is to study asymptotic zero distribution of multivariate random polynomials as their degrees grow. For a smooth weight function with super logarithmic growth at infinity, we consider random linear combinations of associated orthogonal polynomials with subgaussian coefficients. This class of probability distributions contains a wide range of random variables including standard Gaussian and all bounded random variables. We prove that for almost every sequence of random polynomials their normalized zero currents become equidistributed with respect to a deterministic extremal current. The main ingredients of the proof are Bergman kernel asymptotics, mass equidistribution of random polynomials and concentration inequalities for subgaussian quadratic forms.

Herbal Alternative for Kidney Stone Diseases

Kidney stone disease is an increasing disorder of humans. It affects about 12% of the world population. Epidemiological data have shown that calcium oxalate is the predominant mineral in a majority of kidney stones. [1] It has been associated with an increased risk of end-stage renal failure. Kidney stones result from a succession of several physicochemical events including super saturation, nucleation, growth, aggregation, and retention within the kidneys. Kidney stones may cause extreme pain and blockage of urine flow .The average life time risk of stone formation has been reported in the range of 5-10 %.Recurrent stone formation is a common part of the medical care of patients with stone disease.[2] Kidney stone disease is usually treated with medications that may cause a number of side-effects. Even improved and besides the high cost that imposes, compelling data now suggest that exposure to shock waves in therapeutic doses may cause acute renal injury, decrease in renal function and an increase in stone recurrence. Data from in vitro, in vivo and clinical trials reveal that phytotherapeutic agents could be useful as either an alternative therapy in the management of urolithiasis. The present review therefore critically explains the potential usefulness of herbal medicines in the management of urolithiasis.

Effects of crown height on the compensatory growth of Italian ryegrass based on combined effects of stored organic matter and cytokinin

AbstractThe interaction between stored organic matters in crowns and leaf cytokinin induced by roots was determined to investigate the compensatory growth of Italian ryegrass (Lolium multiflorum. Lam). The experiment comprised five treatments: (a) clipping once with 5 cm crown height, (b) clipping once with 2 cm crown height, (c) clipping twice with 5 cm crown height, (d) clipping twice with 2 cm crown height and (e) no clipping. Results showed that low crowns and single clipping promoted regrowth and the sum total of all previously clipping and final harvest of Italian ryegrass. Super compensatory growth and compensatory growth, which were assessed based in total biomasses, respectively, occurred in Italian ryegrasses with high crowns and single defoliation and those with high crowns only. Increased leaf net photosynthetic rates in Italian ryegrasses with high crown were promoted by stored organic matter in crown and leaf cytokinin in the first and later 7‐day regrowth periods, respectively. Compared with single clipping, frequent clipping decreased the stored organic matter in roots; causing decreases in leaf cytokinin concentration and photosynthetic rate. The delivery rate of cytokinin from the roots to the leaves determined the leaf cytokinin concentration in Italian ryegrass during the regrowth period. Thus, organic matters from crowns and leaf cytokinin induced by roots played a combined effect on aboveground compensatory growth in the Italian ryegrasses.

Practical Applications of “Super Growth” Stocks

Practical Applications Summary In “Super Growth” Stocks, from the Summer 2018 issue of the Journal of Investing, Wai Mun Fong of RCF Capital presents a strategy for building a portfolio of stocks of extremely profitable companies, with relatively low book-to-market (BM) ratios. Guided by the clean surplus accounting model of stock pricing, the author derives a “super growth” (SG) portfolio as the foundation of his strategy. Using quintile arrangement as a sorting mechanism, the author classifies companies by their gross profitability and stocks by their BM ratios, and then builds his portfolio using stocks of the most profitable companies (measured by the ratio of gross profits to the book value of assets) that also have low, but not extreme, BM ratios. The author then compares his SG stock portfolio with other embodiments of the growth stock paradigm such as a traditional “growth” portfolio (stocks of companies with extremely low BM ratios) and the Russell 1000 Growth Index. He finds that the SG has generally (and sometimes dramatically) outperformed these other yardsticks over the past several decades, across a variety of performance measures such as mean annual return and Sortino and Sharpe ratios. The author advises investors seeking to improve their overall and risk-adjusted returns to focus on less-extreme growth stocks of highly profitable companies.
