We assessed the influence of vase solution pH and preservative substances on cut flower quality of (Rosa hybrida cvs. Avalanche and Black Magic), gerbera (Gerbera jamesonii cv. Beaudine) and lily (Lilium × elegans cv. Fangio) under room (20±2 °C) and cold storage (4±1 °C) conditions. Cut flowers were placed in four different acidic (pH, 3.5 – 4) or basic (pH, 7.0 – 7.5) preservative solutions containing water, sugar 5% (flower food), 100 mg/L silver nitrate (AgNO3, bactericide), or a commercial product (2% sugar + bactericide and fungicide). Acidic solutions had higher or similar (never lower) vase life at both room and cold storage conditions and across species. In addition, vase life was 3-4 times longer in cold storage when compared to room conditions. Leaf chlorophyll concentration for rose and lily were inconsistent or not significant across the species at both conditions (room and cold storage). The commercial preservative solution consistently and significantly had higher vase life than water for all tested cut flower species and under both room and cold storage environment. AgNO3 ranked second in terms of vase life enhancement. Overall, the use of only flower food (sugar) or bactericide (AgNO3) had a positive impact on vase life but only the combined use of preservative substance (specifically at pH, 3.5 – 4.0) consistently guaranteed a high cut flower quality across flower species.

Wheat is a significant source of carbohydrates and proteins and needs large amounts of fertilizers for high yield. Every year we have to apply tons of nitrogen fertilizer, which increases the cost of wheat production. To reduce the requirement of fertilizer, nitrogen-efficient varieties can play a crucial role. To achieve these targets, thirteen wheat varieties were grown under low and high nitrogen levels. Data was collected from both treatments on various morpho-agronomic traits, i.e., plant height, leaf area number of days to 50% heading, number of grains per spike, thousand-grain weight, dry straw matter maturity, leaf senescence, grain yield, and harvest index. The nitrogen contents of the soil, stem, leaves, and grains were determined and utilized to assess nitrogen uptake efficiency, nitrogen utilization efficiency, nitrogen use efficiency, and nitrogen harvest index. The analyzed data showed that Sahar 2006 and Faisalabad 2008 outperformed for yield, and most of the agro-morphological outcomes contributing traits under low nitrogen level. The varieties Chakwal 86, Faisalabad 2008, and Sahar 2006 showed good performance for most of the nitrogen use efficiency-related parameters, as well as these varieties are the most nitrogen use efficient varieties.

The increase in life expectancy and elderly global population are making the interest on anti-aging products become more expressive. It is well known that an important skin aging mechanism, intrinsic or extrinsic, is oxidative stress. Reactive oxygen species (ROS) in excess damage cell structures leading to integrity loss and visible changes. Antioxidants are molecules able to prevent or eliminate ROS damage, so their oral or topical supplementation is important to slow down the aging process. In this work, we evaluated Vitis vinifera L. extract antioxidant potential. The sample thin-layer chromatography (TLC) profile obtained demonstrated Rf values comparable to the standard phenolic compounds rutin and quercetin. Total phenolic content found using Folin-Denis assay was 3.02 mg of pyrogallol.g-1. Antioxidant potential was performed by DPPH•, ABTS•+ and AAPH• methods and the results indicated a good antioxidant activity with IC50 (mg.mL-1) values of 0.071, 0.101, 0.001 found from each method, respectively. In addition, the extract was incorporated (1%) into the formulations studied, in which sensory ingredients were varied. Accelerated stability study was conducted with the emulsion that presented best sensory characteristics. The organoleptic parameters appearance, color and odor were evaluated, as well the physicochemical parameters, pH (6.43-7.05) and density (0.7875-0.9297 g/cm3), and the microbiological parameters through microbial count. The tested formulation was found to be in compliance with current standards and has the potential to be further studied and used as an anti-aging cosmetic.

A pecuária representa na Amazônia uma atividade de grande valor histórico, onde o estado de Rondônia possui grande dependência da pecuária como geração de renda, entretanto o modo inadequado de produção extensiva tem acarretado a degradação das pastagens devido a perda de qualidade física e química do solo. Diante da problemática encontrada no manejo do solo em áreas de pastagens, o presente trabalho teve como objetivo avaliar os efeitos da compactação e calagem sobre os atributos químicos do solo e a produção forrageira do capim-braquiária em um Latossolo Vermelho-Amarelo distrófico na Amazônia Ocidental. O experimento foi instalado no Campus experimental da UNIR em Rolim de Moura – RO com delineamento experimental em blocos ao acaso, em esquema de parcelas subdivididas, com três repetições. As parcelas consistiam nos estados de compactação, sendo eles zero, uma, duas e seis passadas do trator, e nas subparcelas doses de calcário, sendo zero, três, seis e doze toneladas ha-1. Os dados obtidos foram submetidos à análise de variância e, quando significativa foi aplicado o teste de Tukey para os tratamentos qualitativos e de regressão para os tratamentos quantitativos. Foram analisados os atributos químicos do solo: pH, H+Al, Al, Ca, Mg, K e P e a matéria seca da forragem. Quanto a compactação do solo não interferiu nos atributos químicos do solo, onde somente a calagem interferiu nesse aspecto, As doses de 3 mil e 6 mil kg ha-1 apresentaram melhores resultados para os aspectos químicos do solo, o excesso de calagem prejudicou a disponibilidade de magnésio e fósforo e a relação Ca:Mg, para a matéria seca apresentou interação entre os tratamentos, onde compactação apresentou influência na produção da fitomassa na dose de 12 t. ha-1 que representou uma redução de 30%.

K-C-Means clustering algorithms are known effective within the image segmentation. They can be easy to use as compared to some other methods just like Segmentation approach using Massive Training Artificial Neural Network (MTANN) in existence. Moment, accuracy, and iterations are already the major focus. But there are even now limitations about MTANN using predetermined number of groupings which generates overlapping effects and not being capable to segment colored pictures until they are transformed into grey scale. The proposed method will provide best results with Fuzzy K-C-means Segmentation with respect to Carcinoma and Cirrhosis. Object Delineation Time varies at its minimum is 17.9856 with proposed method.

Inter-firm relation complexity has been an interesting research area for academics and businesses practices due to its relevance in determining the best practices and impacts to the encourage a sustainability supply network. The contribution of this research extend to the literature and put forward solutions for the industry since previous studies are neglecting whole network relations, which is highlighted as source of supply network complexity (SNC). Specifically, this research extends to enriching the literature and recommending solutions to the industry players since previous studies are neglecting important Inter Firm Relation (IFR) elements i.e. formal inter-firm relation (FIFR) and informal inter-firm relations (IIFR), which are highlighted as a pertinent factor in this research towards encouraging a sustainable supply network. In this study, the Social Network Analysis (SNA) method was adopted to develop valid attribute for the measurement process and the embeddedness theory was used to evaluate the IFR among the proposed attributes. This study found that FIFR and IIFR have different effects towards the formation of Sustainable Supply Network Structure (SSNS). Finally, theoretical and industrial implications are also discussed.
