1. Antecedents and Consequences of Three Selling Strategies in Social Enterprises
Abstract Purpose This paper analyzed the effect of a long-term strategic orientation and selling capability on three selling strategies, and their effect on the social impact of hybrid social enterprises. Theoretical framework This study relied on the conceptual effect of a long-term orientation and selling capability on selling strategies, as well as the

2. A New Approach to the Splitting Factor Preconditioner Applied to Linear Programming Problems
ABSTRACT In this paper, we present the results of a new approach to the splitting factor preconditioner, which is a preconditioner based on the Incomplete Cholesky factorization and the splitting preconditioner. In previous work for small linear programming problems, the preconditioner was applied in all iterations of the interior point method and compared w

3. Universal Approximators: New Approach for the Curve Fit of the COVID-19 Infected Population
ABSTRACT Fuzzy systems that include Takagi-Sugeno inference method with linear outputs, are widely known to have the ability to uniformly approximate any polynomial with high precision and, as a consequence, any continuous function, by applying the approximation theorem of Weierstrass. There is one more advantage for these methods which is to obtain an expli

4. Three Different Strategies for Repair of Symptomatic or Aneurysmatic Aberrant Right Subclavian Arteries
ABSTRACT Introduction: In this study, we aimed to present three different methods for symptomatic aberrant right subclavian artery (ARSA) surgery. Methods: We identified 11 consecutive adult patients undergoing symptomatic and/or aneurysmal ARSA repair between January 2016 and December 2020. Symptoms were dysphagia (n=8) and dyspnea + dysphagia (n=3). Six

5. An alternative route to extract nickel and cobalt from non-commercial laterite ore
Abstract Laterite ores, which represent around two-thirds of nickel reserves, became an important source of nickel and cobalt metals. The objective of the present study was to investigate the efficiency of a hybrid route to extract nickel and cobalt present in a laterite ore sample which was not commercially attractive to be processed through the current rou

6. Genetic divergence and combined selection for traits that provide high agronomic performance in common bean lines
ABSTRACT The selection of common bean lines with intermediate cycle, upright plant architecture and high grain yield is an important goal of breeding programs. This study proposes to examine the genetic diversity of common bean genotypes for agronomic traits, select superior genotypes for traits that provide high agronomic performance and define promising cr

7. PREPARATION OF HYBRID POLYMERS AND USE AS CONTROLLED RELEASE DELIVERY VEHICLE FOR VOLATILE REPELLENT TO CONTROL Aedes aegypti
The Zika virus is a flavivirus spread by the Aedes aegypti mosquito, which also transmits dengue and chikungunya. Current forms of control include elimination of mosquito breeding sites, use of insecticides, repellents and other means. The present study developed new adsorbent materials based on silica and biomaterials capable of releasing an Aedes aegypti m

8. Inhibition of Acetylcholinesterase by Coumarin-Linked Amino Acids Synthetized via Triazole Associated with Molecule Partition Coefficient
A previous study for the identification of acetylcholinesterase (AChE) inhibitors demonstrated that the hybrid between tyrosol, the 1,2,3-triazole nucleus, and the coumarin group, namely 7-({1-[2-(4-hydroxyphenyl)ethyl]-1H-1,2,3-triazol-4-yl}methoxy)-4-methyl-2H-chromen-2-one (10), has a high enzyme inhibitory activity. Here, we synthesized analogues of 10 v

9. Synthesis of Sparse Arrays Based On CIGA (Convex Improved Genetic Algorithm)
Abstract In this paper, a novel hybrid algorithm on beam pattern synthesis of sparse arrays is proposed, which aims at minimizing the peak sidelobe level (PSLL). Sparse arrays can provide higher spatial resolution and relatively lower sidelobe than general arrays, but it is necessary to solve the multi-constraint problem of nonconvex nonlinear. Thus, we prop

10. Stability Indicating Method for Determination of Benznidazole and Its Degradation Products in Active Pharmaceutical Ingredient
Currently, treatment of Chagas disease is restricted to the use of benznidazole and nifurtimox; however, nifurtimox was temporarily suspended in some countries. Based on the limitations in pharmacological treatments, it is essential to guarantee the quality of benznidazole. Therefore, this work aimed to identify the degradation products of benznidazole and t

11. Surgical Treatment of Atrial Fibrillation: Cutting Through the Edges
Abstract Medical management of atrial fibrillation can be complex, challenging and requiring time to prove its effectiveness; furthermore, the response can be refractory and inconsistent if the underlying pathology is not permanently addressed. Surgical ablation has become a key intervention, and since its first intervention in 1987 (the Cox-maze procedure),

12. PMMA-SiO2 Organic-Inorganic Hybrid Coating Application to Ti-6Al-4V Alloy Prepared through the Sol-Gel Method
Siloxane-poly(methyl methacrylate) (PMMA) hybrid was synthesized based on the sol-gel method and applied to Ti-6Al-4V through dip-coating. The structural feature of the hybrid was subjected to Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TG); its morphological properties were analyzed through scanning electron microscope (SE
