Authors: Savescu Petre
Published: February 2020

Both green and black tea are known by the consumers for their chemical composition rich in polyphenols � substances with an important antioxidant effect, proofing the capacity to fight against free radicals and to strengthen the immunity system. In order to improve the sensorial characteristics of green and black tea, the main food additives used are natural and synthetic sweeteners. Knowing how to choose the best sweetener for organic green and black tea is a duty of any specialist in this field, in order to improve the capacity to make nutritional recommendations � taking into consideration the different health level of the consumers (especially the ones with diabetes or cardiovascular symptoms or diseases, digestive or hormonal problems or allergies).
The present paper shows a personal method for finding of the best synthetic or natural sweeteners that can be used for sweetening the organic green or black tea coming from areas without any contamination. This method allows the selection of optimal sweetener by monitoring the oxidative status of internal and external environment for green and black tea.

Authors: Carac Andreea , Boscencu Rica , Dediu Andreea Veronica , Bungau Simona Gabriela , Dinica Rodica Mihaela
Published: February 2020

The physicochemical properties and the redox potential of two pyridinium compounds, a diquaternary salt of 4,4�-bipyridinium (BP) and one of 1,2-bis(4-pyridyl)ethane (BPE) were studied. Cyclic voltammetry on platinum electrode was used to evaluate the solvent influence on the redox properties of the pyridinium compounds. Electrochemical measurements were performed in aqueous media, ethanol and aprotic solvent. The solvent variation causes changes in the electro-oxidation processes of the heterogeneous electron transfer at the applied potential. The presence of the ethylenic group in the structure of BPE presents slightly different electrochemical behaviour compared to BP. The corroboration of the electrochemical data with absorption spectral results attests that it�s more likely that the ECE sequence is responsible for the reduction mechanism of pyridinium compounds.

Authors: Kong Song Il , Borcea Anca , Matei Vasile , Ciuparu Dragos
Published: February 2020

The gas-phase etherification reaction of ethanol with tert-butyl alcohol (TBA) was investigated for the production of an oxygenated fuel additive. The reaction was carried out in a continuous flow reactor, in the presence of 12-tungstophosphoric acid (HPW) dispersed on MCM-41 as catalyst. We have studied the influence of temperature, ethanol:TBA mole ratio, and weight hourly space velocity (WHSV) on the TBA conversion and ETBE selectivity. The optimum operating conditions were found at 110oC temperature, 8:1 ethanol:TBA mole ratio in the feed, and 30% HPW loading on the catalyst. The highest ETBE yield values were obtained at 110 �C and WHSV of 46 h-1 and 42 h-1. The HPW/MCM-41 catalyst showed good activity and on-stream stability for the gas-phase synthesis of ETBE at 110oC, thus it is a promising catalyst for etherification reactions and, potentially, for other gas phase acid-catalyzed reactions.

Authors: Craciun Viorel , Voinitchi Dorinel , Badanoiu Alina , Voinitchi Radu
Published: February 2020

The paper presents results regarding the mechanical properties of concretes prepared with various amounts of recycled concrete aggregate (RCA). RCA was obtained by the crushing of concrete rubble resulted during the demolition of a block of flats. The concretes with RCA were prepared using three different mixing approaches: one stage mixing (1SM), two stages mixing (2SM) and two stages mixing with polyvinyl acetate addition (2SM PA). Two stages mixing method in the presence of polyvinyl acetate addition, leads to an improvement of the mechanical strengths (compressive and splitting tensile strength due to a better bonding between the binding matrix formed in the new concrete and the old mortar adhered at the surface of RCA grains.

Published: February 2020

Although the relation between periodontitis (PD) and systemic disorders (e.g. cardiovascular diseases, diabetes and rheumatoid arthritis) is widely accepted, the association with ankylosing spondylitis (AS) is inconsistently mentioned. We prospectively examined the relationship between periodontal disease and AS, focusing on the rate and course of PD, factors associated with severity and the impact of anti-TNF-a treatment on inflammatory status. Standard assessments performed twice (week 0, week 24) included an extensive dental evaluation (plaque index, gingival index, bleeding on probing, periodontal pocket depth, clinical attachment loss), inflammatory parameters and AS activity scores (BASDAI, ASDAS-CRP). More than half of AS presented with impaired periodontal health at baseline (mild to moderate PD) meaning increased sites with dental plaque, abnormal bleeding, increased periodontal pocket depth and clinical attachment loss. Significant positive correlation between presence and severity of PD, AS activity and systemic inflammation (CRP) was reported at baseline (p[0.05). A final analysis performed at 24 weeks revealed significant improvement in periodontal status, inflammatory parameters and AS activity, suggesting efficacy of TNF inhibitors directed not only against systemic, but also on local (articular, periodontal) inflammation (p[0.05). Patients with AS are at risk to develop periodontal disease, particularly those with high levels of systemic inflammation. Benefits of anti-TNFa therapy in the particular settings of AS patient and concomitant periodontal disease should be validated through further studies in larger cohorts.

Published: February 2020

There are numerous phytochemicals (isoflavones, flavonoids, catechins, anthocyanins, carotenoids, polyphenols, phenolic acids), which are largely used in the pharmaceutical industry. This research describes the process through which, one can obtain medicinal extracts from mistletoe (Viscum album L.) and garlic (Allium sativum L.) while giving an exact characterisation of the two extracts. The HPLC/MS analysis was employed in order to identify and evaluate the presence of phenolic acids (gentisic acid, chlorogenic acid, p-coumaric acid, ferulic acid and sinapic acid) and of flavonoids (hyperoside, isoquercitrin, rutin and luteolin). The results suggest that these medicinal extracts could replace the chemical compounds used in various therapies and which unfortunately have side effects on patients.

Published: February 2020

Squalene is natural occurring polyprenyl compound with a linear triterpene chemical structure commonly found in animal and vegetal sources such as skin lipids from human body, liver of certain species of fish, especially sharks, crude vegetable oils (e.g olive, amaranth, palm oil etc.). Recently there has been an increasing interest in studying polymers that can be used as promising emulsions for drug delivery and vaccine applications. Recent studies proved that squalene has several beneficial and unique properties such as natural antioxidant, ensure skin hydration, biocompatibility. This can be used as such or for preparing stable and non-toxic emulsions. Herein we present the preparation and characterization of squalene oil-in-water emulsions stabilized by different non-ionic emulsifiers. Emulsion stability is a primary concern, therefore physical stability of squalene emulsions was also investigated. The major aim of the study was to find the optimal preparation conditions and assessing emulsion stability correlated with their viscosity and composition. In order to establish the connection between their physical stability and viscosity were performed rheological studies.

Authors: Vasile Andrei , Danciulescu Valeriu , Gheorghita Tanase , Kim Lidia , Dediu Violeta
Published: February 2020

Urbanization and the rise in the standard of living generated both a higher quantity of waste and the expansion of cities with the incorporation of solid waste landfills located originally outside. In many cities across Romania, landfills are placed very close to settlements, and in some cases even inside cities. Beside landfill activities, other companies that deal with waste sorting, recycling and treatment operates nearby. All these activities generate odorous compounds that create odour nuisance. The current study was conducted in order to evaluate the impact of a landfill located in a highly urbanized area using dynamic olfactometry with the main objective to assess the level of odour concentration and the impact on the population. Samples were taken around the landfill always from a point opposite to the wind direction. Also, in parallel with odour sampling it was determined the concentration of two main chemical specific compounds, NH3 and H2S, in order to verify the compliance with environmental legislation, and the level of VOC to establish a correlation with the odour level. Measurement results indicate a high level of odour concentration in most of the samples, a good correlation with VOC and frequent exceeded values for the specific chemical compounds. Annoyance level was also high and it was evaluated using FIDOL factors, which are Frequency, Intensity, Duration, Offensiveness and Location.

Published: February 2020

In this work, a synthetic effluent containing Methylene blue dye has been treated by novel membrane enriched with commercial gooseberry buds extract using a mini-laboratory electrodialysis cell. The electrodialysis system was operated at various time and constant voltage applied at electrodes. Methylene blue removal percentage (CR %) and energy consumption (E.C.) were calculated. The obtained results showed that pH increase in solution and lead to an increase of deprotonated methylene groups, which may favor methylene dichloride complex formation. The values of CR % and E.C. increased with time. The high value of CR % was obtained at 60 min(CR] 89 %). The membranes were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and Environmental Scanning Electron Microscopy (ESEM).

Published: February 2020

The marigold extracts are used in traditional medicine for its anti-inflammatory, decongestive, antiseptic, antifungal, antimicrobial and immunostimulating properties. Existing studies have partially proved these properties, but are incomplete with regard to the possibility of standardizing the extract using the best working conditions so as it to be included in dietary supplements. The purpose of this study is to investigate the chemical composition of the marigold extracts, their contents in flavonoids and polyphenolic compounds, as well as to determine the contents in oligoelements of the plant material through the ICP-OES method. Based on the results of this study we conclude that a complete extraction may be accomplished after lyophilizing the solution of hydroalcoholic extract, followed by extraction in acid medium so as to permit a better assessment of the bioactive compounds.

Published: February 2020

Matrix metalloproteinases (MMPs) are a group of endopeptidases with the role of reorganizing the extracellular matrix of cells through the body. In aqueous humor MMPs have an important role in turnover regulation by acting on the constant remodeling of the trabecular mesh keeping at a constant level the trabecular resistance for a good aqueous humor outflow and consequently of the intraocular pressure.In this paper, we aimed to assess the levels of MMP-2/TIMP-1 and MMP-9/TIMP-2 ratio in aqueous humor samples and in the plasma of patients with open angle glaucoma and cataract patients that serves as control, and to evaluate the gelatinolytic activity MMP-2 and MMP-9 in aqueous humor samples. Aqueous humor and plasma samples were collected from 30 patients, 14 from open angle glaucoma and 16 from cataract patients. Levels of MMP-2, -9 and TIMP -1 and -2 were determined by zymography and immunoassays, using specific kits. The data obtained suggest the presence of a direct correlation between the levels and activity of MMP influencing the accumulation of abnormal matrix and may have an impact on the pathogenesis of open angle glaucoma.\

Published: February 2020

An important aspect of orthodontic microimplants is represented by biocompatibility and avoidance of infection development at living tissue surrounding it. Therefore, nanotechnology has the ability to improve this issue by coating microimplants with metal oxides type nanomaterials possessing antimicrobial effect. Some features of advanced nanostructured materials used as implant coatings, such as composition, structure, specific surface area, porosity, shape and size are factors that make them suitable as antimicrobial agents. The present work deals with the structural and morphological studies of ZnO and TiO2 nanoparticles used to combat oral diseases. Coating microimplants with nanosized titanium oxide (TiO2) and zinc oxide (ZnO) may improve conditions for osseointegration in accordance with preventing oral infection. These metal oxides nanopowders were synthesized using sol-gel method. Structural and morphological investigation were carried out by XRD and FTIR spectra, SEM-EDX and TEM images respectively. XRD and FTIR analyses confirmed metal oxides crystallization and metal oxide bonds. SEM-EDX and TEM features confirmed elemental composition of these nanoparticles and their textural characteristics such as shape, size, porosity and agglomeration degree.

Published: February 2020

Boron is a member of the metaloid group of elements and is an important essential microelement needed for normal crop growth and development. This research was conducted in 2015 in Hatay (Mediterranean region of Turkey) to determine foliar application of Boron effect on protein ratio, starch ratio and oil yield and oil components of corn. To evaluate the response of foliar application of boron to corn, four boron doses (control, 4, 6 and 8 mg/m2) were applied at the three growing stages (V2; 2 leaves with visible collars, V4; 4 leaves with visible collars,V2V4; half dosage was applied V2 and half dosage was applied V4). The experiment was carried out in a split plot design with three replicates using cultivar 82 May 70. Ears were harvested and randomly selected for analysis of protein ratio, starch ratio, oil yield and fatty acid composition. Even though there was no significant difference in Boron treatments in terms of protein and starch, significant difference was determined in oil yield and fatty acid composition. In general, foliar application of higher Boron doses (6, 8 mg /m2) increased oleic acid, palmitic acid, stearic acid. In the early development period (V2), foliar application of boron caused an increase in the content of linoleic acid and linolenic acid of corn.

Published: February 2020

Preeclampsia is a syndrome that affects approximately 2-8% of all pregnancies [1] and is closely linked to a particularly elevated inflammatory response, its presence resulting in high maternal and neonatal mortality. Several adipokins have been found to be involved in this process. Visfatin is a cytokine that exerts its effects especially on metabolism and immunity. In this study we determined the serum profile of Visfatin using the ELISA technique, to the 40 patients diagnosed with preeclampsia and we compared it to 16 pregnant patients without complications. Patients with preeclampsia had lower, but statistically not significant plasma levels compared to those in the control group, 11.04 � 7.14 (3.57-17.97) vs 8.88 � 7.91 (1.37-17.85). The lowest Visfatin levels have been recorded in the most severe form of preeclampsia. Visfatin does not significantly influence the birth weight of the foetuses (p = 0.08).
A Computational Study of a Prebiotic Synthesis of the Steroid Progesterone (C and D Rings)
Authors: Aylward Nigel
Published: February 2020

The magnesium ion metalloporphyrin complex is shown to bind the ligands propyne (p) and ethyne (e) on the metal or nitrogen pyrrole sites as a two site catalyst in their copolymerization. The order of addition of the monomers is (pepee). The steroid ring D (pep) is formed first from the propyne adduct bound to the metal site and the but-diene adduct bound to the N-site. The optimal orientation of these adducts determines the β-orientation of the 17-substituent. Further reaction with hydroxyl radicals allows this to be a 17 β- acetyl substituent. Further addition of two ethyne monomers forms an N-diene cyclopentene derivative able to cyclise to form the steroid ring C (pee) with a trans conformation and a 13-β methyl substituent. The reactions have been shown to be feasible from the overall enthalpy changes in the ZKE approximation at the HF and MP2 /6-31G* level, and with acceptable activation energies.

Semiotic Machine
Authors: Nadin Mihai
Published: February 2020

A semiotic machine, no matter how it is embodied or expressed, has to reflect the various understandings of what the knowledge domain of semiotics is. It also has to reflect what methods and means support further acquiring knowledge of semiotics. Moreover, it has to express ways in which knowledge of semiotics is tested, improved, and evaluated. Given the scope of the endeavor of defining the semiotic machine, the methodological approach must be anchored in the living experience of semiotics. Accordingly, the cultural-historic perspective, which is the backbone of any encyclopedic endeavor, is very much like a geological survey for a foundation conceived from a dynamic perspective. The various layers could shed light on a simple aspect of the subject: At which moment in the evolution of semiotics does it make sense to make the association (in whatever form) to tools and to what would become the notion of a machine? Reciprocally, we would have to explain how the various understandings of the notions tool and machine are pertinent to whatever was the practice of semiotics at a certain juncture. Yet another reference cannot be ignored: The reductionist-deterministic view, celebrated in what is known as the Cartesian Revolution. Since that particular junction in our understanding of the world, the reduction of semiotic processes to machine descriptions is no longer a matter of associations (literal or figurative), but a normative dimension implicitly or explicitly expressed in semiotic theories. Given this very intricate relation, we will have to systematize the variety of angles from which various understandings of the compound expression semiotic machine can be defined.In our days, such understandings cover a multitude of aspects, ranging from the desire to build machines that can perform particular semiotic operations to a new understanding of the living, in view of our acquired knowledge of genetics, molecular biology, and information biology. That the computer—a particular form of machine—as an underlying element of a civilization defined primarily as one of information processing, could be and has been considered a semiotic machine deserves further consideration.
A-signifying Semiotics
Authors: Genosko Gary
Published: February 2020

This paper offers an interpretation of the theory of a-signifying semiotics developed by French intellectual-activist Félix Guattari in the 1970s. The argument is that these types of part-signs are perfectly adapted to the quasiautomated networks of contemporary infocapitalism, and their characteristics are studied with regard to the magnetic stripe on a plastic bank or credit card. Although these part-signs are akin to signals since they do not have a semantic dimension, they do have a political materiality in the technologies, that is, the information strands of the machinic phylum, in which they are found. This technomaterialist semiotics of infocapital places Guattari at the forefront of innovative semiotic theory.
Conceptual blending and sign formation
Authors: Kowalewski Hubert
Published: February 2020

In this article I will investigate the process of conceptual blending involved in sign formation. The main objective of this article is to demonstrate that conceptual blending theory is capable of accounting for the creation of both linguistic and non-linguistic signs from pre-existing semiotic inventory. Moreover, like in the case of logos and names of certain products, the conceptual mechanism behind the formation of linguistic and non-linguistic signs is similar not only in general aspects, but also in fine-grained details. This statement is by no means paradoxical. The theory of conceptual blending strives to describe the basic conceptual mechanism responsible for the semiotic capabilities of the human mind and is not intrinsically connected with any specific type of signs; thus, cognitive strategies which prove to be effective for the creation of, for instance, graphic signs may be reused for the creation of linguistic signs.
The spatial dimension of history: propagation of historical knowledge via open-air museums, leisure parks and motion pictures
Authors: Ickerodt Ulf
Published: February 2020

Man's environment is full of references to history. Archaeological sites and cultural landscapes are examples. History is a constituent of our social identity. In this sense, on a social level, it has an integrating function and helps to structure and canalize social behaviour. In this paper we shall examine, taking archaeological sites, open-air museums, leisure parks and motion pictures as examples, how this form of promotion of history works and what effect it has on society.
A Peircean approach to pictorial documents
Authors: Jappy Tony
Published: February 2020

The paper summarizes six chapters of a book introducing Peircean visual semiotics to non-specialists. The book has an epistemological bent, and is intended as an empiricist response to Saussurean rationalism, locked away as it is in the universe of Thirdness. Inevitably, in reducing two hundred and thirty pages to twenty-four, the paper has been shorn of the majority of the original examples, quotations and summaries, the relations between the various chapters (here sections) are not developed in detail and the general presentation is perforce allusive: for example, the dynamic object, surely one of Peirce’s most potent yet least understood concepts, has been simplified in what is, after all, an introductory text; similarly, acquaintance with his system of categories has largely been taken for granted. Finally, Simonides of Ceos’ epigram stating that a poem is a talking painting and a painting a mute poem gives the book its title and a major leitmotiv, namely the way we obtain information from pictorial documents.
