Negative pressure wound therapy, staged excision and definitive closure with split-thickness skin graft for axillary hidradenitis suppurativa: a retrospective study
Authors: Pearce F.B. , Richardson K.A.
Published: January 2017

Objective:

Bilateral axillary hidradenitis is a chronic, suppurative, and scarring disease that is most effectively treated by complete excision of all hair-bearing tissues. We assessed our staged procedure for excision and placement of a split-thickness skin graft for bilateral axillary hidradenitis in terms of costs, outcomes, and timing of excision.

Method:

An IRB approved retrospective case analysis was performed on patients that underwent bilateral axillary hidradenitis skin excision with eventual placement of split-thickness skin grafting using the current LSUHSC/University Health hidradenitis surgical treatment protocol. Using ICD-9 codes (705.83) and CPT codes (11041, 11042, 11451, 11600, 11601, 11602, 11603, 11604) we reviewed cases performed at our institution from 1 January 2008 to 24 Febuary 2014 and we selected patients based on bilateral axillary involvement (alone) and >1 year history of active disease. Patients were excluded if resection of tissue encompassed regions outside of the immediately adjacent axillary.

Results:

A total of seven patients matching criteria for bilateral axillary hidradenitis were selected for analysis. Clinical course, cost and surgical techniques were assessed. Of the seven patients, six required admission throughout their treatment due to lack of funding making use of negative pressure wound therapy at home not possible. These patients stayed an average of 10 days with a mean hospital charge of $35,178 and a mean hospital provider charge of $10,019. No recurrence was demonstrated. All patients attained full range of motion, post grafting. No patient required a further operation due to graft failure.

Conclusion:

Split-thickness skin grafting without use of bilayer dermal regenerative templates yielded definitive results with acceptable cosmesis and functionality, without the added cost of treatments such as a bilayer dermal regenerative template.
Clinic visit frequency in wound care matters: data from the US wound registry
Authors: Carter M.J. , Fife C.E.
Published: January 2017

Objective:

A previous study suggested that the frequency with which patients visit wound care clinics influences the rate of chronic wound healing but high bias was present with regard to wound care centre selection. The objective of this retrospective cohort study was to confirm this finding by using a very large sample size of diabetic foot ulcers (DFUs) from the US Wound Registry.

Method:

Patients who visited the clinic more than once for a new DFU were eligible for study inclusion. No exclusion was made with regard to Wagner grade, wound severity, or patient comorbidity. A Cox regression was conducted to analyse time to heal within 1 year using covariates known or suspected to influence wound healing, including visit frequency.

Results:

In terms of relative effect size, covariates that impeded wound healing the most were wound age and visit frequency with lower visit frequencies associated with lower probabilities of wound healing. Compared with DFUs (n=39,750) seen at a frequency of 7.5 times or more per 4 weeks, wounds seen at intervals of 2 weeks or less had a hazard ratio of 0.098 [(95% confidence interval: 0.09-0.11]. Using a separate breakpoint of ≥2 versus < 2 per 4 weeks specifically for the estimate of overall effect size, Cohen's w was 0.14—a small-to-medium effect size.

Conclusion:

Our findings confirm previous work and have implications for clinical practice and analysis of uncontrolled studies.

Este artículo explora la construcción de una opinión pública en Costa Rica acerca de la guerra en Nicaragua entre los sandinistas y La Contra en 1986-1987 y sobre la política internacional de Costa Rica frente a ese conflicto y frente a los propósitos de expansión de la guerra del presidente estadounidense Ronald Reagan. Se revisan las opiniones emitidas por varios intelectuales costarricenses acerca del plan de paz de Óscar Arias y la construcción que hicieron de su imagen entre 1986 y 1987. Queda en evidencia que en su afán de producir un total apoyo al plan de paz, los intelectuales costarricenses promovieron acríticamente a Arias como un héroe nacional, regional y casi mundial.

Cytochemical and Ultrastructural Studies on the Cell Walls of Tllrallsfocllyfrillm spp.
Authors: Chamberlain A. H. L.
Published: January 2017

The structure of the wall at various stages in the life cycle of three species of Thraustochytrium. marine coccoid fungi. has been examined. The cell walls are composed of two elements; thin organic Golgi·derived scales and a fibrillar inter-scale matrix. Cytochemical procedures have established the presence of protein and sulphated polysaccharide in the walls together with associated calcium. The presence of sulphur and calcium has been confirmed by energy dispersive E.M. X-ray analysis. These new features have been considered from the taxonomic viewpoint and appear to strengthen the concept that some affinities exist between the Thraustochytriales and the algal protists.
Distribution and Ecology of Marine Fungi in Sierra Leone (Tropical West Africa)
Authors: Aleem A. A.
Published: January 2017

The distribution of marine fungi in Sierra Leone is studied in the light of hydrographic and climatic factors.

Altogether 27 spp. have been identified to species level, comprising 3 Phycomycetes 14 Ascomycetes and 10 Deuteromycetes. All these spp. are considered as new records to the country and about 50 % of them are inhabitants of mangrove swamps under tidal influence.

The climate of Sierra Leone is characterized by two main seasons: a wet season (May - November) and a dry season (December-April).

Mangrove mycota display a seasonal periodicity, increasing in number of spp. and growth intensity in the wet . season. Degradation of wood was also active during this season, apparently more by members of Deuteromycetes such as Cirrenalia spp., Periconia prolifica and Zalerion spp. than by Ascomycetes.

Sea foam was also richer in fungal ascospores (including 6 spp. of Corollospora) and conidia of Deuteromycetes in the wet than in the dry season.

Estuarine foam. however. comprises several Hyphomycetes of freshwater or terrestrial origin brought in by runoff during the rainy season (e.g. Alternaria, Curvularia, Drechslera, A cro sporidium , etc.)

No distinct vertical zonation was displayed by the lignicolous fungi inhabiting the mangrove.

The geographical distribution of the higher marine fungi under consideration has been compared with those on the opposite side of the Atlantic as well as in the Pacific and Indian Oceans. Out of 24 spp. found in Sierra Leone, 21 spp. (88 %) occur on the opposite side of the Atlantic. while an equal number is known in the Pacific. Only 15 spp. (63 %) are recorded in the Indian Ocean. The last figure is due to our limited knowledge of Indian Ocean fungi and is expected to increase in future.

The distribution of mangrove fungi encountered in Sierra Leone is considered as a "community" comprising host specific forms such as Leptosphaeria avicenniae and Cytospora rhizophorae, as well as facultative forms. Out of 14 such spp. in Sierra Leone, 13 (93 %) occur in the Western Atlantic. 12(86 %) in the Pacific and 10(72 %) in the Indian Ocean so far. The close affinities of mangrove fungi in the 3 oceans, paralleled with similar affinities of mangrove floras lend support to the theory of a common center in the West-Indo Pacific for the mangrove flora and associated mycota from which a drift took place in various directions into the 3 oceans in question. The theory was postulated by Ekman (1953) for the distribution of tropical fauna and found support by Macnae (1968) for the distribution of the mangrove flora and fauna. It also allows for an endemic element as the drift deviates from the center.

The closer affinities between Eastern and Western Atlantic mycota could be explained by the current gyres to the north and south of the equator and their role in transporting mangrove seeds. wood and associated fungi between the African arid American coastlines.
Distribution and Seasonality of Macroalgae on Oyster Communities of Central Chesapeake Bay
Authors: Connor Judith L.
Published: January 2017

Field studies of the benthic macroalgae of fifteen selected Chesapeake Bay oyster communities were conducted over a period of a year (March 1977 to February 1978). Algal distribu tion and seasonal occurrence were studied in relation to changes in the physical environment. Salinity, temperature, and light availability were important factors in the spatial and temporal distributions of algae in these subtidal habitats.

Seventeen species of Chlorophyta, Phaeophyta, and Rhodophyta were recorded from the fifteen study sites distributed over 130 kilometers within the Maryland portion of Chesapeake Bay. Species of Chlorophyta were associated with oyster communities throughout the year of study with maximum numbers of species and maximum biomass occurring in spring. Only once was a member of the Phaeophyta encountered; a single filamentous species, Ectocarpus, was collected during winter. Species of Rhodophyta were present throughout the year at the study sites.

Most of the algae collected reproduced asexually by spores and/or vegetative fragments. Sexual reproduction occurred in some of the red algal species. The presence of tetrasporic and cystocarpic plants of Dasya baillouviana and Polysiphonia harveyi var. olneyi may indicate that the usual triphasic Florideophycean life history occurs in this estuary.
Activity of the liver enzyme ornithine carbamoyltransferase (OTC) in blood: LC-MS/MS assay for non-invasive diagnosis of ornithine carbamoyltransferase deficiency
Authors: Krijt Jakub , Sokolová Jitka , Ješina Pavel , Dvořáková Lenka , Řeboun Martin , Brennerová Katarína , Mistrík Martin , Zeman Jiří , Honzík Tomáš , Kožich Viktor
Published: January 2017

Background:

Liver enzymes are released from hepatocytes into circulation and their activity can be measured in the blood. We examined whether the plasma activity of the liver enzyme ornithine carbamoyltransferase, determined by a novel liquid chromatography-mass spectrometry (LC-MS/MS) assay, could be utilized for the detection of OTC deficiency (OTCD), an X-linked inborn error of the urea cycle.

Methods:

The plasma ornithine carbamoyltransferase (OTC) activity was assayed in the reverse reaction using isotopically labeled citrulline-d4 as a substrate and by determination of the product, ornithine-d4, by LC-MS/MS analysis.

Results:

The plasma OTC activity in the controls was in the range of 111–658 pkat/L (n=49, median 272 pkat/L), and the activity increased linearly with serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities in patients with hepatopathy. The OTC activity was subsequently determined in 32 individuals carrying mutations in the OTC gene, and OTC/ALT and OTC/AST ratios were calculated to account for the degree of hepatopathy, which is a common finding in OTCD. The OTC/ALT ratio enabled clear differentiation of OTCD hemizygotes (n=11, range 0–69×10−6) from controls (504–3440×10−6). This ratio also enabled the detection of 11 of 12 symptomatic heterozygotes (range 38–794×10−6), while this marker did not allow for reliable differentiation of asymptomatic heterozygotes (n=9) from controls.

Conclusions:

LC-MS/MS assay of plasma OTC activity enabled the detection of all hemizygous and the majority of symptomatic heterozygous OTCD patients in the tested cohort. This study demonstrates that non-invasive assay of enzymes expressed predominantly in the liver could be used as an alternative approach for diagnosing inborn errors of metabolism.

Background:

α

Methods:

Sixteen buccal swab samples from previously characterized AATD patients were analyzed using an allele-specific genotyping assay and sequencing method. In addition, 19 patients were characterized by quantification, phenotyping and genotyping using only serum samples.

Results:

The 16 buccal swab samples were correctly characterized by genotyping. Definitive results were obtained in the 19 serum samples analyzed by quantification, phenotyping and genotyping, thereby performing the complete AATD diagnostic algorithm.

Conclusions:

Buccal swab samples may be useful to expand AATD screening programs and family studies. Genotyping using DNA from serum samples permits the application of the complete diagnostic algorithm without delay. These two methods will be useful for obtaining more in depth knowledge of the real prevalence of patients with AATD.

Authors: Bisoi Soumendu , Mandal Arun Kumar , Singh Asheesh , Banerjee Susanta
Published: January 2017

A series of new polyamides (PAs) has been prepared from a Troeger base-bridged diamine (TB), 2,8- diamino-4,10-dimethyl-6H,12H-5,11-methanodibenzo[1,5]-diazocine and different commercially available diacid monomers via the conventional polycondensation method. Dense membranes were prepared from the PAs by solution casting and solvent evaporation techniques. The synthesized PAs showed high glass transition temperature (283–290°C), 10% weight loss up to temperature 431°C in air, and tensile strength up to 91 MPa. The PA membranes showed higher permeability than some commercially used glassy polymers (PCO2 up to 109 and PO2 up to 21 Barrer) and permselectivity (PCO2/PCH4 up to 53.7 and PO2/PN2 up to 7.52) in comparison to many other PAs published in the literature.

Published: January 2017

Atmospheric corrosion is one of the main factors leading to performance deterioration of reinforced concrete buildings; and, hence, periodic structural condition monitoring is required to assess and repair the adverse effects of corrosion. However, this can become a cumbersome and expensive task to undertake for large populations of buildings, scattered in large urban areas. To optimize the use of available resources, appropriate tools are required for the assessment of corrosion risk of reinforced concrete construction. This paper proposes a framework for the production of digital corrosion risk maps for urban areas; Cyprus was used as a case study. This framework explored multi-temporal satellite remote sensing data from the Landsat sensors as well as corrosion risk factors derived from the results of a recently completed research project, entitled “STEELCOR”. This framework was used to develop two corrosion risk scenarios within Geographical Information Systems, and to produce corrosion risk maps for three coastal cities of Cyprus. The thematic maps indicated that, for slight corrosion damage, the distance of reinforced concrete buildings from the coast was more influential than the building age. While, for significant corrosion damage, the maps indicated that the age of RC buildings was more influential than the distance from the coast.
Detection of olive oil mill waste (OOMW) disposal areas using high resolution GeoEye’s OrbView-3 and Google Earth images
Authors: Agapiou Athos , Papadopoulos Nikos , Sarris Apostolos
Published: January 2017

The olive oil industry is considered to be as one of the driving sectors of the agricultural economy of the Mediterranean basin. The extraction of olive oil generates huge quantities of wastes that may have a great impact on land and water environments due to high concentrations in phenolic compounds that could cause ophytotoxicity. This paper aims to examine the potential use of freely distributed satellite images for the detection of olive oil mil waste (OOMW) areas in the island of Crete through the use of two cases studies. In the first case study an archive GeoEye OrbView-3 image was used to detect OOMW areas using the Spectral Angle Mapper detection algorithm and other geometric and topographic parameters. In the second case study, Google Earth images were examined through different classification algorithms at different scales. The overall results demonstrate that remote sensing techniques can be used as an alternative to field observations so as to detect and monitor OOMW areas Furthermore, freely distributed RGB images from digital globes (such as Google Earth) can be sufficiently and effectively used for this purpose.

Electron spin resonance signals of quartz in present-day river bed sediments and possible source rocks in the Kizu River basin, Western Japan
Authors: Shimada Aiko , Takada Masashi , Toyoda Shin
Published: January 2017

In this study, measurements of electron spin resonance (ESR) signals from quartz grains from present-day river bed sediments of the Kizu River basin (western Japan) were used to estimate the mixing ratios of the possible source materials of these fluvial deposits. The dose-saturated ESR signal intensities obtained from the Al and Ti-Li centers in quartz grains were close to the range between the maximum and minimum intensities of their potential source rocks, meaning it was possible to estimate the mixing ratios of these sources. The results indicate that the dose-saturated Al and Ti-Li center ESR intensities can be used to quantitatively estimate the provenance of the sediments deposited by the Kizu River.
OSL dating of the late Quaternary slip rate on the Gyaring co Fault in central Tibet
Authors: Wang Duo , Yin Gong-Ming , Wang Xu-Long , Liu Chun-Ru , Han Fei , Du Jin-Hua
Published: January 2017

The Gyaring Co Fault (GCF) is an active right-lateral strike-slip fault in central Tibet that accommodates convergence between India and Asia in the interior of the Tibetan Plateau. The average long-term slip rate of the fault remains controversial, given the absence of absolute age data of faulted geomorphic features. We have applied optically stimulated luminescence (OSL) dating to the northern segment of the GCF, revealing that the GCF has displaced alluvial fans at Aerqingsang by 500 ± 100 m since their deposition at ~109 ka, yielding a slip rate of 4.6 ± 1.0 mm/yr. A slip rate of 3.4 ± 0.4 mm/yr is inferred from analysis of an alluvial fan with an offset of 65 ± 5 m (~19 ka) at Quba site 1. The Holocene slip rate is estimated to be 1.9 ± 0.3 mm/yr, as inferred from the basal age (~8.3 ka) of terrace T1 that has a gully displacement of 16 ± 2 m at Quba site 2. These slip rates are generally lower early estimates (10–20 mm/yr), but are consistent with more recent results (2.2–4.5 mm/yr) and GPS data for other strike-slip faults in this region, indicating that deformation may be distributed across the entire Tibetan Plateau. Moreover, we suggest that the slip rate along the GCF may have decreased slightly during the late Quaternary.

Published: January 2017

The hydrazide 5, that was obtained from 1-(4-fluorophenyl)piperazine (1), was converted to the corresponding carbothioamides 6a–c by the reaction with alkyl(aryl) isothiocyanates. The synthesis of conazole analogs 10a–f was performed via the intermediary of triazoles 7a–c. The condensation of triazoles 7a–c with several heterocyclic amines in the presence of formaldehyde afforded the corresponding N-aminoalkylated triazoles 11–14. The effect of different catalysts and solvents on conventional and microwave (MW)-prompted reactions was examined. The synthesized compounds were screened for their antimicrobial activities.
Characterization of the precipitated lignin from Japanese beech as treated by semi-flow hot-compressed water
Authors: Takada Masatsugu , Minami Eiji , Yamauchi Kazuchika , Kawamoto Haruo , Saka Shiro
Published: January 2017

Japanese beech (Fagus crenata) was decomposed by a semi-flow process in hot-compressed water (HCW) at 150~230°C/10 MPa for 25 min. Mainly hemicelluloses and partly the lignin moiety of the wood was affected and liquefied in water. A part of the liquefied products can be precipitated after 12 h standing at ambient conditions. The precipitates are composed of around 90% of lignin, which was quantified and characterized by various chemical and spectroscopic methods in comparison of milled wood lignin (MWL), which is considered to be a representative compound for the native lignin in wood. The yield of the precipitated lignin (Lprecip) is higher than that of MWL and its syringyl content is also higher as demonstrated by alkaline nitrobenzene oxidation (NBO) giving rise to higher syringaldehyde/vanillin (SA/VA) ratios. Its OHphen group content was also high. The interpretation is that Lprecip is mainly from the secondary wall, and accordingly, the presented semi-flow HCW treatment offers the possibility for an efficient lignin isolation.
A Grain Output Combination Forecast Model Modified by Data Fusion Algorithm
Authors: Wan Xiang , Liu Bing-Xiang , Xu Xing
Published: January 2017

To deal with the lack of accuracy and generalization ability in some single models, grain output models were built with lots of relevant data, based on the powerful non-linear reflection of the back-propagation (BP) neural network. Three kinds of grain output models were built and took advantage of – particle swarm optimization algorithm, mind evolutionary algorithm, and genetic algorithm – to optimize the BP neural network. By the use of data fusion algorithm, the outcomes of different models can be modified and fused together, and the combination-predicted outcome can be obtained finally. Taking advantage of this combination model to predict the total grain output of China, the results showed that the total grain output in 2015 was a bit larger than the actual value of about 0.0115%. It was much more accurate than the three single models. The experimental results verify the feasibility and validity of the combination model.

Published: January 2017

Numerical investigation for the effect of thermal stratification on MHD flow and heat transfer of dusty fluid over a vertical stretching sheet embedded in a thermally stratified porous medium in the presence of uniform heat source and thermal radiation. The governing equations for the problem were reduced in to dimensionless ordinary differential equations using suitable similarity transformations. The transformed nonlinear ordinary differential equations are numerically solved by applying efficient RungeKutta Fehlberg-45 Method with shooting technique. The effects of various flow controlling parameters such as Prandtl number, heat source/sink parameter, fluid particle interaction parameter, heat source parameter, radiation parameter on velocity and temperature distributions of both fluid and dust phases are depicted graphically. Finally, the numerical results are compared and found to be in good agreement with previously published results under special cases. The results indicate that the fluid phase velocity is always greater than that of the particle phase and thermal stratification significantly affects the surface shear stress as well as the surface heat transfer.
FUT8: from biochemistry to synthesis of core-fucosylated N-glycans
Authors: Calderon Angie D. , Li Lei , Wang Peng G.
Published: January 2017

Glycosylation is a major posttranslational modification of proteins. Modification in structure on N-glycans leads to many diseases. One of such modifications is core α-1,6 fucosylation, which is only found in eukaryotes. For this reason, lots of research has been done on approaches to synthesize core-fucosylated N-glycans both chemically and enzymatically, in order to have well defined structures that can be used as probes for glycan analysis and identifying functions of glycan-binding proteins. This review will focus on FUT8, the enzyme responsible for core fucosylation in mammals and the strategies that have been developed for the synthesis of core fucosylated N-glycans have been synthesized so far.
Hybrid nanocomposites made of diol-modified silanes and nanostructured calcium hydroxide. Applications to Alum-treated wood

Published: January 2017

The alum-treated Viking Age archaeological wooden objects from the Oseberg find have undergone extensive chemical deterioration due to the original conservation treatment, based on alum salts (KAl(SO4)2·12H2O), done in the early 1900s. Today, the artifacts are highly acidic (pH≤2) and fragile; in some cases wood has almost completely lost its structural integrity. Research on conservation methods for these finds is currently underway. In the present study, organic/inorganic multi-functional ‘hybrid systems’ – using propylene glycol modified TEOS and alkaline nanoparticles (Ca(OH)2) – have been engineered to deacidify and consolidate alum-treated wood in a single step. The advantage of using silicon monomer and nano-materials as a starting point resides in their ease of penetration into the wood structure, where silicon monomers subsequently undergo polymerization. Treated samples were investigated using thermal analysis (DTG), X-Ray Diffraction (XRD), infrared spectroscopy (ATR-FTIR), SEM/EDX and Gas Chromatography Mass Spectroscopy (GC-MS). Results suggest that in addition to consolidating the wood, alkoxysilanes could act as a bridging agent between remaining lignin and calcium hydroxide nanoparticles.
Spectroscopic ellipsometry characterization of spin-coated Ge25S75 chalcogenide thin films
Authors: Janicek Petr , Slang Stanislav , Palka Karel , Vlcek Miroslav
Published: January 2017

Spectroscopic ellipsometry study on spin-coated non-toxic Ge25S75 thin films annealed at different temperatures were conducted. Multi sample analysis with two sets of samples spin-coated onto soda-lime glass and onto silicon wafers was utilized. Optical constants (refractive index n and extinction coefficient k) of these films were determined from ellipsometric data recorded over a wide spectral range (0.05–6 eV). Different parametrization of Ge25S75 complex dielectric permittivity which consists of a Tauc-Lorentz or Cody-Lorentz oscillator describing the short wavelength absorption edge, a Lorentz or Gauss oscillators describing phonon absorption or optically active absorption of alkyl ammonium germanium salts in the middle infrared part of spectra is discussed. Using a Mott-Davis model, the decrease in local disorder with increasing annealing temperature is quantified from the short wavelength absorption edge onset. Using the Wemple-DiDomenico single oscillator model for the transparent part of the optical constants spectra, a decrease in the centroid distance of the valence and conduction bands with increasing annealing temperature is shown and increase in intensity of the inter-band optical transition due to annealing temperature occurs. Intensity of absorption near 3000 cm−1 could be used as alternative method to evaluation of quality of prepared films.

Structure and phase composition of titania aerogels can be substantially influenced simply by the process of drying their parent water colloid suspensions prepared by the reaction of hydrogen peroxide with suspension of precipitates obtained by neutralization of solution of titanyl sulfate with ammonia. Two methods of drying are compared: (1) lyophilization of fast frozen material immersed in liquid nitrogen, and (2) critical point drying using supercritical CO2 under high pressure. Both methods of drying lead to yellow titanium peroxide aerogels consisting of nanometer-sized blocks. While lyophilization leads to foils consisting of nano-sized crystalline nuclei of peroxo-polytitanic acid dispersed in predominantly amorphous material, the critical point drying provides rather bulk highly porous composite consisting of randomly oriented flat nanoparticles (5–10 nm) composed of crystalline anatase and amorphous peroxo-polytitanic acid.

Published: January 2017

The anisotropic mechanical properties of parts that are fabricated using acrylonitrile butadiene styrene (ABS) polymer relative to part-built orientation employing the fused deposition modelling process are reported in this work. ABSplus-P430 polymer was used to investigate the effects of infill orientation on the parts’ mechanical properties under tensile and compression loading. Results revealed that infill orientation strongly affected the tensile properties of fabricated ABS samples. Specifically, the values for Young’s modulus ranged from ~1.5 to ~2.1 GPa, ultimate tensile strength from ~12.0 to ~22.0 MPa, yield strength from ~1.0 to ~21.0 MPa, and elongation-at-break from ~0.2 to ~4.8% for different infill orientations. Samples with infill orientation aligned to the vertical (i.e. Z-) axis displayed the highest values relative to all other infill orientations investigated. Mechanical properties anisotropy was lower for parts under compressive loading, such that the Young’s modulus, ultimate compressive and yield strength were weakly correlated with infill orientation apart from samples whose built orientation was aligned at 45° to the vertical Z-axis. The latter samples displayed inferior mechanical properties under all compressive tests. The effects of sample gauge thickness on tensile properties and ABS sample micro- and bulk- hardness with respect to infill orientation are also discussed.

Diglycolic acid modified zirconium phosphate (ZrP-DGA) was prepared and studied for the extraction of Am(III) and Eu(III) from dilute nitric acid medium. The distribution coefficient (Kd, mL·g−1) of Am(III) and Eu(III) was measured as a function of time, pH and concentration of Eu(III) ion etc. The Kd of Am(III) and Eu(III) increased with increase of pH, reached a maximum value of distribution coefficient at pH 1.5 – 2, followed by decrease in Kd values. Rapid extraction of Am(III) and Eu(III) in ZrP-DGA was observed followed by the establishment of equilibrium occurred in 100 min. Kinetics of extraction was fitted in to pseudo second order rate equation. The amount of Eu(III) loaded in ZrP-DGA increased with increase in the concentration of Eu(III) ion in aqueous phase and the isotherm was fitted in to Langmuir and Freundlich adsorption models. The extraction of Am(III) in ZrP-DGA was higher as compared to Eu(III) and the interference of Eu(III) on the extraction of Am(III) was studied. The distribution coefficient of some lanthanides in ZrP-DGA was measured and the Kd of lanthanides increased across the lanthanide series. The extracted trivalent metal ions were recovered in three contacts of loaded ZrP-DGA with 0.5 M nitric acid.
Integrating neurobiology of emotion regulation and trauma therapy: reflections on EMDR therapy
Authors: González Anabel , del Río-Casanova Lucía , Justo-Alonso Ania
Published: January 2017

Emotion dysregulation is a frequent feature in trauma-related disorders. Different kinds of emotion dysregulation seem to be linked to particular psychiatric conditions, and there is growing evidence of the association between neurobiological correlates and those dysregulation patterns. Nevertheless, many of the recent findings from the field of the neurobiology have not been translated into clinical practice and are insufficiently contemplated in trauma-oriented therapies. The aim of this article is to review recent developments in the field of emotion regulation connecting these issue with the practical implementation of psychotherapeutic procedures. The evaluation of emotion dysregulation patterns can guide decision making during the therapy independently to the approach, but there are some findings that can be especially useful for some concrete modalities of therapy. In this article we will focus our discussion on how emotion dysregulation may influence eye movement desensitization and reprocessing (EMDR) treatment in trauma-related disorders. EMDR is a well-defined and protocol-based intervention, with a strong empirical support for post-traumatic stress disorder (PTSD). We describe how different patterns of emotion dysregulation may influence EMDR treatment and procedures, and also how the application of EMDR beyond non-dissociative PTSD should take into account the predominant emotion-regulation strategies in specific posttraumatic disorders.

Published: January 2017

Objective

We aimed to investigate the frequency of delayed notifications and probable causes of delays for critical value notification in clinical laboratory of university hospital.

Materials and methods

All data was obtained from critical value reporting forms and laboratory information system. The frequency and location of critical and delayed results, latencies throughout a working day and the professional status who received the critical callbacks were shown as percentages.

Results

A total of 2018 (1.02%) critical values were reported and 13.1% of them were delayed notifications. Most of them were observed in laboratory tests ordered from patients of service and polyclinics compared to ICU and emergency department (26.7%, 26%, 6.2% and 4.9%, respectively, p<0.01). Delayed notifications were significantly higher for biochemical parameters (19.7%, p<0.001) and observed particularly in morning hours (06:00 a.m.–10:00 a.m.), lunch break time (12:00–14:00) and end of the working day (16:00–18:00). Latencies of mild-delayed reporting were 18.5±4.4 min for 62.8% and advanced-delayed reporting were 47.1±11.3 min for 37.2% of total delayed notifications. Most of the critical results were reported to the health care staff other than physician (55.6%).

Conclusion

Laboratory professionals should work in collaboration with responsible clinician and healthcare staff in critical value reporting process.

Published: January 2017

Three new bismuth arylsulfonatocarboxylates [Bi(OH)(SB)] (1), [Bi4(ST)2(HST)O2(H2O)2]·H2O (2) and [Bi4(ST)2O3(H2O)2] (3) were synthesized under solvothermal reaction conditions at 180°C using the potassium or sodium salt of 4-sulfobenzoic acid (H2SB) and 2-sulfoterephthalic acid (H3ST), respectively. The compounds were characterized in detail and the crystal structures were determined from single crystal X-ray diffraction data. Phase purity was confirmed by powder X-ray diffraction and elemental analysis. Structural comparisons to the only three other known bismuth sulfonatocarboxylates are presented. Due to the higher reaction temperatures employed for the synthesis of the title compounds a higher degree of condensation of the BiOx polyhedra (X=7 or 8) to tetrameric units, 1D chains or a 2D layer is observed. Connection through the organic linker molecules leads to the formation of 3D coordination polymers in all three title compounds.

Published: January 2017

In this article, a generalised Whitham–Broer–Kaup–Like (WBKL) equations is investigated, which can describe the bidirectional propagation of long waves in shallow water. The equations can be reduced to the dispersive long wave equations, variant Boussinesq equations, Whitham–Broer–Kaup–Like equations, etc. The Lie symmetry analysis method is used to consider the vector fields and optimal system of the equations. The similarity reductions are given on the basic of the optimal system. Furthermore, the power series solutions are derived by using the power series theory. Finally, based on a new theorem of conservation laws, the conservation laws associated with symmetries of this equations are constructed with a detailed derivation.

Published: January 2017

The investigation of liquid bridge force acting between wet particles has great significance in many fields. In this article, the exact solution of capillary force between two unequal-sized spherical particles is investigated. Firstly, The Young-Laplace equation with moving boundary is converted into a set of ordinary differential equations with two fix point boundary using variable substitution technique, in which the gravity effects have been neglected. The geometry of the liquid bridge between two particles is solved by shooting method. After that, the gorge method is applied to calculate the capillary-bridge force that is consists of contributions from the capillary suction and surface tension. Finally, the effect of various parameters including distance between two spheres, radii of spheres, and contact angles on the capillary force are investigated. It is shown that the presented approach is an efficient and accurate algorithm for capillary force between two particles in complex situations.

Authors: Mukhtar Asma , Zaheer Muhammad , Saeed Muhammad , Voelter Wolfgang
Published: January 2017

Development of catalysts for efficient conversion of lignin polymer to value-added materials requires appropriately-functionalized lignin model compounds. The predominant structural feature of lignin biopolymer is an extensive network of β-O-4 linkages. Access to large amounts of a model compound containing the β-O-4 linkage is crucial for the valorisation of lignin biopolymer to aromatic raw materials. Starting from commercially available vanillin, synthesis of dilignol model compound, containing a β-O-4 linkage, is accomplished in good overall yield.
Theoretical Study of the Ti–Cl Bond Cleavage Reaction in TiCl4
Authors: Nurkowski Daniel , Jasper Ahren W. , Akroyd Jethro , Kraft Markus
Published: January 2017

In this work the kinetics of the TiCl4 ⇌ TiCl3 + Cl reaction is studied theoretically. A variable-reaction coordinate transition-state theory (VRC-TST) is used to calculate the high-pressure limit rate coefficients. The interaction energy surface for the VRC-TST step is sampled directly at the CASPT2(6e,4o)/cc-pVDZ level of theory including an approximate treatment of the spin-orbit coupling. The pressure-dependence of the reaction in an argon bath gas is explored using the master equation in conjunction with the optimised VRC-TST transition-state number of states. The collisional energy transfer parameters for the TiCl4–Ar system are estimated via a “one-dimensional minimisation” method and classical trajectories. The Ti–Cl bond dissociation energy is computed using a complete basis set extrapolation technique with cc-pVQZ and cc-pV5Z basis sets. Good quantitative agreement between the estimated rate constants and available literature data is observed. However, the fall-off behaviour of the model results is not seen in the current experimental data. Sensitivity analysis shows that the fall-off effect is insensitive to the choice of model parameters and methods. More experimental work and development of higher-level theoretical methods are needed to further investigate this discrepancy.
