The objective of this work was to choose an optimal rate of citric acid and sweeteners for lemon flavoured drops. Two model samples with defined concentrations of citric acid and two commercial samples were evaluated with using instrumental and sensory methods. Concentrations of sweetening agents and citric acid in the samples were determined using HPLC with a RI detector and isotachophoresis, respectively. The general pleasantness of taste and the intensity of acid and sweet tastes of four lemon drops were evaluated using sensory analysis. General pleasantness was evaluated using a ranking te

Abstract:
Abstract Hydrochloric acid (HCl) is an important mineral acid with many uses, including the pickling of steel, acid treatment of oil wells and chemical cleaning and processing. This acid is extremely corrosive and its aggressiveness can change drastically depending on its concentration, the temperature and contamination by oxidizing impurities. One of the most commonly encountered oxidizing impurities is the ferric ion. In general, stainless steels cannot tolerate aggressive HCl solutions, hence the need to use corrosion-resistant nickel-based alloys. A part of this study focused on the role o

Abstract Economic pressures on the refining industry are forcing many refiners to look at lower priced high acid crudes to improve margins. These crudes may be discounted because they are perceived to cause increased corrosion or fouling problems, or simply because they are new or unknown to the market. If these problems are not properly managed or understood, the benefits of lower price may be consumed by higher processing costs or by the deterioration of the assets caused by corrosion. To safely process these high acid crudes, a comprehensive multi-discipline service has been implemented to

The corrosion rate can be calculated considering the hydrofluoric acid concentration, the presence of air and the alloy content of Cr, Ni, Mo and Cu.

Abstract Materials research has led to the selection of alloys and identification of operating conditions that enable substantial increases in steam production and thermal efficiency in the sulfuric acid manufacturing process. Corrosion mechanisms in concentrated (98 to 100%) sulfuric acid change significantly at elevated temperature, and selected stainless steels are found to have unexpected low corrosion rates at temperatures ranging from 120°C to over 200°C. Corrosion resistance can be related to the concentrations of major alloying elements.

Objectives: 1) Clarification of the mode of potentiation of an expressed insect selective neurotoxin (AaIT) by its recombinant baculovirus. 2) In vitro formation and/or modification of neuroactive polypeptides for the design of new improved recombinant baculoviruses. Results: 1) A combined utilization of bioassays, LM-cytochemistry, the highly resolutive EM immunogold and electrical recording from the CNS of baculovirus and AaIT - expressing – recombinant baculovirus infected larvae it has been shown that the recombinant virus potentiates the effect of the toxin. Potentiation is achieved throu

Abstract:
The overall goal of this research work was to identify the main proteolytic activities which take place in the digestive tracts of young bass fish, and use the knowledge acquired in order to improve feed protein utilization in juvenile fish based on their digestive capacity. The results of the work clearly showed that the young fish possess the entire profile of proteolytic enzymes which is found in adult fish. Yet, in the young fish the level of activity is substantially lower per gram tissue (or gram protein) as compared with the activity found in the digestive tracts of the same fish at an

Abstract:
This review is undertaken to answer the following questions: Key Question 1: What is the effectiveness of dental services in improving health outcomes in people with human immunodeficiency virus (HIV) before, during, or after HIV treatment? Key Question 2: What are the clinical practice guidelines or standards for dental care for people with HIV? Key Messages: The body of evidence informing KQ1 is limited to three poor-quality single-arm studies evaluating the impact of non-surgical periodontal treatment (NSPT) in HIV-positive patients with periodontitis. Overall, the available data lack direc

Abstract:
Atmospheric deposition can alter biological communities through a variety of pathways. Atmospheric nitrogen (N) deposition causes some plant and animal species to increase growth and/or abundance. Other species then can be outcompeted and eliminated from the biological community. Deposition of reactive N (Nr) to watersheds can impact both aquatic and terrestrial ecosystem elements and contribute to eutrophication and acidification effects. Atmospheric sulfur (S) deposition has been the primary driver of soil and surface water acidification of acid-sensitive ecosystems, resulting in adverse eff

Abstract:
Steroidal glycoalkaloids (SGAs) are secondary metabolites being part of the plant defense response. The two major SGAs in cultivated potato (Solanum tuberosum) are α-chaconine and α-solanine, which exhibit strong cellular lytic properties and inhibit acetylcholinesterase activity, and are poisonous at high concentrations for humans. As SGAs are not destroyed during cooking and frying commercial cultivars have been bred to contain low levels, and their content in tubers should not exceed 20 mg/100 g fresh weight. However, environmental factors can increase tuber SGA content above the safe level

Abstract:
Leguminous forage crops are high in proteins but deficient in S- amino acids. It has been shown that both wool quality and milk production can be limited by the post-ruminal supply of sulfur-containing amino acids. Efforts to use conventional plant breeding and cell selection techniques to increase the S-amino acid content of alfalfa have met with little success. With the objective to increase the S-amino acid content of forage legumes, the goal of this project was to co- express the methionine rich zein genes from corn along with a gene for a key enzyme in methionine biosynthesis, aspartate k

Abstract:
Hollow microneedles are designed to perform intradermal medical substance delivery or fluid extraction, with polymers standing out as cost-effective materials for mass production via injection molding. However, existing research lacks a comparative analysis of different polymers in terms of processability and performance in skin penetration tests. This study addresses this gap by evaluating hollow microneedles fabricated from five biocompatible thermoplastic materials: polycarbonate (PC), polybutylene terephthalate (PBT), polylactic acid (PLA), polyamide 12 (PA12), and glass-fiber reinforced p
