Conservative Treatment of Chronic Mallet Fracture Non-union after Failed Pin Fixation
Authors: A Hara
Published: February 2020

Introduction: Operative treatment of mallet finger fractures is generally recommended for patients in whom more than one-third of the articular surface is involved with volar subluxation. We present a case of conservative treatment with chronic nonunion of a mallet finger fracture after failed mallet finger surgery.

Presentation of Case: A 16-year-old boy presented with a bony fragment (mallet formation) of his left long finger. The fragment occupied 40% of the articular surface, with volar subluxation of the distal phalanx. Percutaneous needle curettage of the fracture site and pinning were performed. Six weeks later, the fragment was displaced and had rotated. Hence, all the pins were removed, and a splint was applied. The fracture displayed nonunion and volar subluxation of the distal phalanx. The patient continued with the splinting, and the fracture finally healed. At 27 months after the surgery, radiological examination showed very good remodeling of the distal interphalangeal joint surface with anatomic joint congruence. Functional results at 27 months were good according to Crawford’s classification.

Conclusion: Chronic nonunion of a mallet finger can be cured conservatively even when a fracture gap is seen along with displacement of the fragment and volar subluxation of the distal phalanx.

Published: February 2020

This paper examines temporal and spatial patterns of annual and seasonal maximum temperatures (Tmax) in Slovenia and their relationship with atmospheric circulation patterns. A significant increase in maximum temperature (Tmax; from 0.3°C to 0.5°C·decade-1) was observed throughout the country at the annual scale in the period 1963–2014. Significant positive trends are observed on all stations in summer (from 0.4°C to 0.7°C·decade-1) and spring (from 0.4°C to 0.6°C·decade-1). The results indicate significant correlations between the mean annual maximum temperature (Tmax) and the East Atlantic Oscillation (EA) (from 0.5 to 0.7), the Arctic Oscillation (AO) (from 0.4 to 0.7) and the Scandinavian Oscillation (SCAND) (from −0.3 to −0.4) throughout the country. A significant EA influence is observed in all seasons, while the AO influence is noticed in winter and spring, SCAND in spring and summer, the North Atlantic Oscillation (NAO) and the Mediterranean Oscillation (MO) in winter, the East Atlantic/Western Russia Oscillation (EA/WR) in summer and the El Nino Southern Oscillation (ENSO) in autumn.
Bio-bibliographic publications on the pages of the «Svoboda» newspaper (1922―1938s)
Authors: Mykhaliuk Malvina
Published: February 2020

Transcarpathian journals of the first half of the XX century are of interest to researchers both as a scientific and periodical heritage as well as an object of bibliographic research. The article deals with the «Svoboda» magazine published in the Transcarpathian terrains, including Uzhgorod in the 1922―1938s. The latter is stored in the holdings of The Vasyl Stefanyk National Scientific Library of Ukraine in Lviv. Based on the combination of logical (analysis, synthesis, generalization) and specific methods (biographical, bibliographic, statistical), the author conducted research on rediscovering little-known ordinary people by retrieving their obituaries in the journal. Subsequently, all issues of the magazine were carefully analyzed. The obituaries were grouped and separated from common prosopography content, names were put alphabetically, and analytical publications published by authors, directly, indirectly or related to research, were established. The rediscovered bio-bibliography material is of great value to researchers and searchers of information about known and forgotten individuals who lived upon the terrains of the Transcarpathia in the 20th century or related directly or indirectly to the territory during the indicated period. The follow-up studies are further research on rediscovering, systematizing and grouping of bio-bibliographic materials in other Transcarpathian journals of the first half of the XX century.

Keywords: «Svoboda» journal, Uzhgorod, obituaries, bio-bibliography.
Batman Rides Again! The Influence of a Superhero Branded Attraction on Visitation to a Casino-integrated Resort in Macao
Authors: McCartney Glenn , Su Man Karen Cheong
Published: February 2020

The global popularity and rise of superhero movies from companies such as Marvel, DC Comics, and Dream Works has led to these superhero icons being increasingly integrated into the event and entertainment industry, through brand alliances at movie theme parks and integrated resort complexes,
or individual attractions such as the Batman Dark Flight (BDF) ride studied in this research. Given the significant costs to license, stage, and maintain superhero branded entertainment zones and rides at integrated resorts (IR), this preliminary study importantly examined the rationale behind
visiting the ride and ultimately the ride's overall influence in IR visitation. Respondents were questioned while queuing for the BDF ride collecting 304 valid responses specifically asked on their level of interest in Batman including the motives for choosing the ride. Notably the study revealed
that the BDF was essentially a peripheral attraction. In the absence of the ride, most respondents would still have visited the IR. Although a preliminary analysis, the findings suggest greater assessment is required on the net economic and competitive worth of event and entertainment hosting
at Macao's IRs and in particular to Chinese audiences who make up most of Macao's visitation and this study sample.

Authors: Bumbac Costel , Manea Elena Elisabeta , Tiron Olga , Badescu Valeriu Robert
Published: February 2020

The balance between biotechnological useful microorganisms species, as well as the aerobic sludge granules morphology influences the treatment plant performance. This paper presents an attempt to correlate the experimental results on wastewater treatment performance with aerobic granular sludge structural community. The experiments were conducted in two lab scale bioreactors operated in parallel at different retention times. Treatment performances achieved in both systems lead to an effluent that complies NTPA001 limits, both systems being able of simultaneous nitrification / denitrification and phosphorus removal. For qualitative and quantitative analysis of aerobic granular sludge specific microorganisms, DNA has been succeesfully isolated and purifyied from sludge samples, thus obtaining bacterial DNA extracts in concentrations of up to 56 ng/mL and 78% purity. The resulted DNA extracts were used for qPCR amplification. Amplification was carried out in the presence of a series of 10 pairs of primers for the detection / quantification of specific bacteria and genes involved in the treatment process: universal bacteria; Micotrix parvicella; Ammonia oxidizing archaea; Ammonium monooxigenase; Nitrobacter Sp.; nitrite reductase; N2O reductase; phosphorus accumulating microorganisms. The experimental results showed a qualitative and quantitative improvement of the sludge quality in terms of species distribution and share of biotechnologically useful bacteria.

Authors: Stefanescu Mihai , Nechifor Gheorghe , Bumbac Costel , Ionescu Ioana , Tiron Olga
Published: February 2020

This paper emphasized the influence of the main operating parameters of ultrasonic biological sludge pretreatment onto disintegration (DD-COD) and solubilizing degree of organic matter content. The optimal ultrasonic reaction time, energy and amplitude of ultrasonic waves and pH of the sludge (non-modified pH and pH 8.5) were established taking into account their influence on the solubility level of COD, an evolution of particles size. Correlations between disintegration degree and dimensional analysis were performed. Ultrasonic reactor operating to 20 kHz ultrasound frequency was a close system having cooling water jacket. Experimental tests in different operating conditions (reaction time 5 � 60 min., ultrasound energy 2000 � 9000 kJ, pH = 6.5/8.5) demonstrated that alkaline ultrasonic treatment (pH = 8.5, initial homogeneous COD = 72600 mg O2/L) at medium - high ultrasound energy levels led to highest disintegration degree � DD 12% (comparing with pH = 6.5 � DD ~ 5%). Still, the process should be managed carefully because of possibility to have important variation of DD during the ultrasonic treatment.

Published: February 2020

This study investigates the synergistic effects of ion exchange and biodegradation methods to remove the Acid Blue 193 also called Gryfalan Navy Blue RL (GNB) dye from wastewater. Ion exchange studies were performed using a strongly basic anion exchange resin Amberlite IRA 400. The equilibrium was characterized by a kinetic and thermodynamic points of view, establishing that the sorption of the GNB dye was subject to the Freundlich isotherm model with R2 = 0.8710. Experimental results showed that the activated resin can removed up to 93.4% when the concentration of dye solution is 5.62�10-2 mM. The biodegradation of the GNB was induced by laccase, an enzyme isolated from white-rot fungus. It was also analyzed the role of pH and dye concentration on GNB biodegradation, so 5�10-2 mM dye had a maximum discoloration efficiency of 82.9% at pH of 4. The laccase showed a very fast and robust activity reaching in a few minutes a Km value of 2.2�10-1mM. In addition, increasing the GNB concentration up to 8�10-1 mM did not triggered a substrat inhibition effect on the laccase activity. Overall, in this study we proposed a mixt physicochemical and biological approach to enhance the GNB removal and biodegradability from the wastewaters and subsequently the environment.

Published: February 2020

A study of precipitation chemistry was conducted from 2006 January to 2016 November in the Ciuc and Giurgeu basin, Eastern Carpathians, Romania. The results show that the natural precipitation in these areas is alkaline, with a volume weighted mean (VWM) of 6.49 and 6.88 in Ciuc and Giurgeu basin, respectively. NH4+ is the most potential species to completely neutralize the rainwater over the Miercurea Ciuc (Ciuc basin) and Toplita (Giurgeu basin) area. However, in the case of Miercurea Ciuc, Ca2+ is also a potential neutralizer. Annual mean percentage concentration of NH4+ within the total principal cations is also proof that ammonium dominates the rainwater chemistry in the atmosphere of the studied basins. A comparison between the annual mean deposition fluxes showed that in the Giurgeu basin concentrations of NH4+ are higher than in the Ciuc basin. Calculations of the neutralization factors (NFs) show that at both sampling sites NH4+ contributed the most to the neutralization process. Ammonium availability index (AAI) has a value of 156.44% and 179.11% for Miercurea Ciuc and Toplia, respectively, indicating excess ammonium over the neutralization value. Fractional acidity (FA) was calculated, indicating that in Miercurea Ciuc 98.74% and in Toplita 99.28% of the rainwater acidity was neutralized. Calculation of the original and measured acidity also showed the neutralization capability of NH4+. Contributions of the marine and non-marine salts and enrichment factors were estimated, helping to identify the possible sources of the major ions in the atmosphere.

Grape skin is considered a valuable by-product for antioxidant and antibacterial agent preparation. The grape skin contains some active compounds, such as, dietary fiber, polyphenols, flavonols, and resveratrol; it is commonly used as a nutritional supplement. The main aim of this study was to establish the optimum dose of grape skin flour, to be used as a functional ingredient in the bakery products industry, from both chemical and rheological point of view. The laboratory experiments evaluated the functional potential of wheat flour enriched with grape skin flour, in different proportions, by examining the chemical composition and rheological behaviour of the doughs. Protein, crude fibre, fat, ash and mineral contents were determined. Using �H-NMR spectral technique, the fatty acids composition was determined, especially the concentrations of short-chain saturated fatty acids (C4-C8), di-unsaturated fatty acids, mono-unsaturated fatty acids and long-chain saturated fatty acids (]C8). 1H-NMR spectra were recorded on a Bruker Ascend 400 MHz spectrometer. The rheological behaviour was analyzed using the predefined Chopin + protocol on Mixolab, an equipment of CHOPIN Technologies. Grape skin flour was incorporated into wheat flour at three different levels, 5, 10 and 15% and it was found that incorporation up to a 15% level into the formulation of wheat flour yielded an acceptable product in terms of rheological parameters, with improved chemical, nutritional and functional properties.

Sweet cherry tree (Prunus avium L., Rosaceae) is a species with high economic efficiency in production and in the last twenty years the scientific interest increased in the North-East region of Romania. In the area of Ia�i in 2014 the combined influence of the fruits position on tree level in different cultivars was recorded in terms of morphological and biochemical characteristics for nine different cultivars ex situ collected. Fruits collected from two different height-levels areas of tree were used for analysis in each cultivar. Fruit pulp and kernel were investigated in terms of biometry, total solids content, vitamin C, total flavonoids (flavones), and polyphenols. Fruit mass and diameter showed higher values in samples collected from the upper side of the tree on Catalina, Scorospelka, Van and Bucium�cultivars, ranging between 5.8 g / fruit to 9.5 g / fruit and 20.6 to 26.3 mm / fruit respectively. Kernel mass was higher on upper side of the tree on Catalina and Marina cultivars, while on Scorospelka, Van, Bucium and Stefan the values were greater on down half of the tree but without statistical signification.

The study investigated the effect of a small alloy addition (1 atomic %) in alloys Fe61Co10Y8Nb1B20, b - Fe61Co10Y8Zr1B20, c - Fe61Co10Y8W1B20, d - Fe61Co10Y8Mo1B20 on the shape of the Mossbauer spectrum and on the distributions of hyperfine field induction on 57Fe obtained from their numerical analysis. The line factor A [2.5] was also determined in the Zemman�s sextet, which is an indirect measure of ordering for the texture of the spins occurring in the volume of alloys. Based on the analysis of the results, it was found that the Mossbauer spectras are typical of amorphous alloys and the hyperfine field distributions are bimodal.

Epinephrine (adrenaline) - C9H13NO3 - was synthesized for the first time by Fredrich Stelz in 1904 from phenylalanine. After a hydrolysis and decarboxylation process, active dopamine is obtained. Following the pathway of other hydroxylation followed by N-methylation, epinephrine synthesis is achieved. Epinephrine has initially been administrated together with procaine in local anesthesia in hand surgery. Epinephrine has been considered to be one of causes of ischemia and necrosis in hand and especially fingers surgery. Over time, studies have shown the efficacy and safety of using lidocaine-associated epinephrine in local hand surgery anesthesia. Numerous advantages regarding the use of lidocaine 1% with epinephrine, solution at a concentration of 1:100,000 have been reported, starting with increasing the duration of anesthesia, avoiding the use of tourniquet, leading to increased patient comfort and to the advantage of a much lower cost in terms of surgery as a whole. Our study group consisted of fifty patients with hand and fingers different patologies. In all cases surgery was performed under local anesthesia using lidocaine 1% with epinephrine, solution at a concentration of 1:100,000. The decrease of doses mentioned in the literature was attempted and in some cases the decrease was up to 30%. There have not been reported any ischemic or necrosis complication in the immediate postoperative period.

The purpose of the work was to perform a numerical analysis, with the FEM method, of anatomical tweezers loaded with the forces of 10 and 50 N. Tweezers consist of two arms connected permanently by welding and are used for holding tissues. ANSYS software was used for the simulation. The force of 10 N expresses the gripping force during correct handling of tweezers, whereas the force of 50 N simulates a very high load on tweezers. Distribution of stresses, deformations and displacements created during tweezers� work was obtained as a result of the simulations conducted.

The dehydration of polysaccharides fraction in the presence of acid catalysts, is a chemical process in which results as secondary product humic matter. In our work, the humic acid mixture was for the first time based on our knowledge extracted from defatted microalgae biomass rich in polysaccharides by standard alkali treatment, followed by precipitation at acidic pH. The dried humic acid mixture has been characterized using infrared spectroscopic measurements (FT-IR). Exfoliated graphite nanoplatelets (xGnP) were used as new adsorbents for this type of humic acids mixture, their adsorption being investigated. The effect of several parameters such as: contact time, concentration of humic acid mixture, concentration of xGnP, temperature and pH of the solutions were studied. The process of adsorption took place with good results, in the following conditions: at a concentration of humic acid mixture of 18.6 mg L-1, an xGnP amount of 0.01 mg in 25 mL of solution, at a temperature of 25 �� and at acidic pH values, in aqueous solution.

The flame propagation in methane-air mixtures diluted by inert additives (He, Ar, N2, CO2) was studied by means of pressure-time records of laminar deflagrations occurring in a spherical vessel with central ignition. Experiments were made using mixtures with various equivalence ratios between 0.610 and 1.310 and various inert concentrations between 5 and 25 vol%, at various initial pressures between 50 and 200 kPa. Examination of pressure-time records in the early stage of explosions delivered the normal burning velocities Su via the coefficients of the cubic law of pressure rise, using a previously described procedure. The propagation velocities (or the flame speed) were calculated from the normal burning velocities using the expansion coefficients of the unburnt gas during the isobaric combustion. The propagation velocities of examined systems obtained from experimental data were examined against the propagation velocities obtained from kinetic modeling of methane-air-inert combustion by means of 1D COSILAB package using the GRI 3.0 mechanism.

Enhancing healthy fatty acids (FA) in lamb tissues is a important research issue in meat science. The present study examined the effects of feeding-protected lipid supplements rich in linoleic acid or linolenic acid on the lipid composition of muscle and adipose tissues of lambs. Thirty, 10-week-old Tsigai breed ram lambs were assigned to one of three experimental diets (forage/concentrate ratio 40:60): no oil Ca soap (C-Control), with 4% sunflower oil Ca soap (SO-high in 18:2n-6), with 4% camelina oil Ca soap (CO-high in 18:3n-3). The diet high in a-linolenic acid (CO diet) produced the highest levels of n-3 FAs: 18:3n-3 (ALA), 20:5n-3 (EPA) and 22:6n-3 (DHA) intramuscular fat. In addition, the animals fed with the diet CO have intramuscular fat the lowest n-6/n-3 ratio, atherogenic (AI) and thrombogenic index (TI). In the intramuscular fat of the animals fed with the diet high in linoleic acid (SO diet), conjugated linoleic acid (CLA) isomers and trans 18:1 reached their highest concentrations. The results of this study indicated that linoleic acid was more effective in enhancing contents of CLA in muscle and adipose tissue than linolenic acid, which contributes to the enrichment of n-3 FA lamb meat. Feeding camelina oil Ca soap has been shown to be the most effective dietary management to improve health lipid indices (n-6/n-3 ratio, AI, TI) in lambs� meat.

Langerhans cells are antigen presenting cells, located in the stratified squamous epithelium of the skin and oral epithelium. A high density of Langerhans cells in gingival epithelium associated with an inflammatory process has been demonstrated in the literature by numerous studies, although the relationship with inflammation was less investigated.The aim of our study was to evaluate the distribution, density, morphology of Langerhans cells in both gingival epithelium and the associated inflammatory infiltrate in the lamina propria of the gingiva. The relationship between Langerhans cells and inflamatory process was also assesed.
The present study included a number of 51 gingival biopsies. 12 of these didn� t show significant changes on routine examination. In all of the other 39 cases the presence of inflammatory lesions was noticed. The inflamatory infiltrate was described by using hematoxylin eosin staining and quantitative score, with values between 0 and 3. Langerhans cells were immunohistochemicaly highlighted by using S100 antibody and quantified with hot spot method.We found an increase of Langerhans cells density in all cases of inflammation as compared with healthy gingival tissue. The highest density was found in the 13 cases with severe inflammation. At these last cases was noticed a migration tendency of Langerhans cells from infiltrate inflamatory area to basal layer of the epithelium. The results of this study indicated that Langerhans cells number is higher in inflamatory gingival tissue comparative with normal tissue, and the density of these cells is in relation with the severity of the inflammatory process.

Dopamine is very important neurotransmitter and the rapid and effective methods for its determination are of great importance in fundamental medical research. A rapid voltammetric assay for dopamine (DA) detection in presence of ascorbic acid (AA) based on an electrochemically pretreated pencil graphite electrode has been investigated. Differential pulse voltammetry results showed two well-distinguished oxidation peaks for DA and AA at 0.369 V and 0.142 V, respectively, and the method was applied for DA determination without previous separation. The obtained detection limit for DA was 5.17 � 10-8 M. The method has been successfully applied for determination of DA in a pharmaceutical sample.

MERCADOS COMO ORDENS SOCIAIS:
Authors: Niederle Paulo Andre
Published: February 2020

A sociologia da agricultura tem presenciado um profícuo debate sobre mercados alimentares. No entanto, este debate ainda é parcialmente obstado por lógicas dualistas que opõem mercados convencionais e alternativos, commodities e singularidades, agronegócio e agricultura familiar. No debate internacional, uma das expressões mais importante deste dualismo revela-se na oposição entre as abordagens dos “regimes alimentares” e “estilos de agricultura”. Após apresentar os limites das mesmas, o artigo propõe um novo diálogo entre a Teoria das Convenções e Teoria das Práticas para introduzir o conceito de mercados como “ordens sociais”. A partir dele, e com base em pesquisas conduzidas desde 2011 sobre a reestruturação dos mercados para alimentos orgânicos, o artigo analisa a configuração de quatro ordens: cívica, estética, industrial e tradicional. Cada ordem comporta nexos específicos de práticas sociais, às quais estão associados dispositivos institucionais e técnicos, bem como múltiplos significados e identidades sociais.
