Objectives The present study describes a novel technique for revitalising allogenic intrasynovial tendons by combining cell-based therapy and mechanical stimulation in an ex vivo canine model. Methods Specifically, canine flexor digitorum profundus tendons were used for this study and were divided into the following groups: (1) untreated, unprocessed normal tendon; (2) decellularised tendon; (3) bone marrow stromal cell (BMSC)-seeded tendon; and (4) BMSC-seeded and cyclically stretched tendon. Lateral slits were introduced on the tendon to facilitate cell seeding. Tendons from all four study groups were distracted by a servohydraulic testing machine. Tensile force and displacement data were continuously recorded at a sample rate of 20 Hz until 200 Newton of force was reached. Before testing, the cross-sectional dimensions of each tendon were measured with a digital caliper. Young’s modulus was calculated from the slope of the linear region of the stress-strain curve. The BMSCs were labeled for histological and cell viability evaluation on the decellularized tendon scaffold under a confocal microscope. Gene expression levels of selected extracellular matrix tendon growth factor genes were measured. Results were reported as mean ± SD and data was analyzed with one-way ANOVAs followed by Tukey’s post hoc multiple-comparison test. Results We observed no significant difference in cross-sectional area or in Young’s modulus among the four study groups. In addition, histological sections showed that the BMSCs were aligned well and viable on the tendon slices after two-week culture in groups three and four. Expression levels of several extracellular matrix tendon growth factors, including collagen type I, collagen type III, and matrix metalloproteinase were significantly higher in group four than in group three (p < 0.05). Conclusion Lateral slits introduced into de-cellularised tendon is a promising method of delivery of BMSCs without compromising cell viability and tendon mechanical properties. In addition, mechanical stimulation of a cell-seeded tendon can promote cell proliferation and enhance expression of collagen types I and III in vitro. Cite this article: J. H. Wu, A. R. Thoreson, A.

Abstract
The aim of this study was to evaluate the dynamic changes of serum lipid and lipoprotein profiles in 6 newborn calves during the first five days of life. From each calve blood sampling was performed daily starting from day 1 (after colostrum intake) until day 5 of life. Blood samples collected from each animal were tested for serum total lipids, phospholipids, non-esterified fatty acids (NEFAs), triglycerides, very low density lipoproteins (VLDLs), total cholesterol (Total-Chol), high density lipoproteins (HDLs) and low density lipoproteins (LDLs). One-way repeated measures analysis of variance (ANOVA) was applied to determine the effect of days of life on the studied parameters in calves. A statistically significant effect of days of life was found on all serum lipid and lipoprotein indices measured in calves with the exception of NEFAs that showed unchanged values throughout the monitoring period. The changes observed in calves during the early postnatal period are most likely due to the transition in energy sources, from a maternal nutrient supply comprising mainly carbohydrates and amino acids to the colostrum and milk diet rich in fat.

AbstractThe aim of this study was to assess the genetic variations and relationships across evolutionary related cervid species in order to estimate the genetic diversity of the Red deer population that inhabits the forest area in the south-western part of Slovakia. The study was based on the application of cross-species SNP genotyping. The genomic data were obtained from a total of 86 individuals representing six genera (Axis,Dama,Cervus,Alces,Rangifer, andOdocoileus) using Illumina BovineSNP50 BeadChip. From 38.85% of successfully genotyped loci up to 1,532 SNPs showed polymorphism and were informative for subsequent analyses of the diversity and interspecific genetic relationships. Generally, a good level of observed heterozygosity was found across all species. The value of FIS(0.23±0.13) signalised the increase of a homozygous proportion within them. The application of molecular variance analysis to the hierarchical population structure showed that most of the variation was conserved within separate species (96%). The performed diversity analysis of Slovak Red deer population and comparative analysis of their phylogenic relationships among subspecies from genusCervusdid not identify a remarkable loss of genetic variability. Also, were not identified any degree of admixture that could be due to the historical background of deer farming in Slovakia or reintroduction and hybridisation by other species from genusCervus(C. canadensis, andC. nippon) which are the major risk of loss of autochthonous Red deer populations in many areas of Central Europe. The analysis of individual’s ancestry showed consistent results with patterns of evaluated group differentiations which means low migration rates among all species.

Abstract
Insulin resistance is a phenomenon which accompanies the ongoing metabolic adaptation in cows during early lactation. The aim of our study was to determine the linear correlations of HOMA (Homeostatic Model Assessment), QUICKI (Quantitative Insulin Sensitivity Check Index) and RQUICKI (Revised Quantitative Insulin Sensitivity Check Index) indexes of insulin resistance with the metabolic status of cows (concentration of hormones, metabolites and body condition score). The experiment included 40 Holstein-Frisian cows in the first week after calving. Indexes of insulin resistance valued: 18.68±5.43 (HOMA), 0.39±0.06 (QUICKI) and 0.45±0.06 (RQUICKI). Linear correlations were examined by testing the coefficient of correlation (r), determination (r2,%) and regression parameter beta (b) in linear equation. A negative correlation was found between HOMA and IGF-I (insulin growth factor I) (r=−0.51, r2=25.0, b=−1.1257, p<0.01). HOMA showed a positive correlation with BHB (betahidroxybutyrate) (r=0.48, r2=23.2, b=0.0234, p<0.01). A positive correlation was found between QUICKI and IGF-I (r=0.30, r2=10.0 b=46.7900, p<0.05) and cholesterol (r=0.44, r2=18.3, b=1.9021, p<0.01). In contrast, QUICKI and BHB (r=0.51, r2=27.1, b=−1.7241, p<0.01), just like QUICKI and BCS (r=0.46, r2=20.9, b=−2.424, p<0.01), showed a negative correlation. RQUICKI showed positive correlations with IGF-I (r=0.48, r2=22.8, b=28.1230, p<0.01), T4 (r=0.47, r2=22.1, b=87.142, p<0.01) and triglycerides (r=0.36, r2=13, b=0.0407, p<0.05) but negative correlations with cortisol (r=−0.36, r2=13.0, b=−9.0332, p<0.05), STH (somatotropic hormone) (r=−0.42, r2=17.3, b=−5.4976, p<0.01), BHB (r=−0.62, r2=38.3, b=−1.1872, p<0.01), total bilirubin (r=−0.58, r2=33.7, b=−7.131, p<0.01) and BCS (body condition score) (r=−0.6, r2=36.4, b=−1.8347, p<0.01). In conclusion, indexes of insulin resistance may be used to evaluate the metabolic status of cows in early lactation. RQUICKI might be the most appropriate predictor of metabolic status due to its linear relationship with most of the parameters included in homeorhetic process.
Emergency Braking of a Mine Hoist in the Context of the Braking System Selection
Authors: Wolny Stanisław 
Published: March 2017

Abstract
The paper addresses the selected aspects of the dynamic behaviour of mine hoists during the emergency braking phase. Basing on the model of the hoist and supported by theoretical backgrounds provided by the author (Wolny, 2016), analytical formulas are derived to determine the parameters of the braking system such that during an emergency braking it should guarantee that:

–the maximal loading of the hoisting ropes should not exceed the rope breaking force,
–deceleration of the conveyances being stopped should not exceed the admissible levels
Results of the dynamic analysis of the mine hoist behaviour during an emergency braking phase summarised in this study can be utilised to support the design of conveyance and rope attachments by the fatigue endurance methods, with an aim to adapt it to the specified operational parameters of the hoisting installation (Eurokod 3).

Abstract
Rate of penetration (ROP) is one of the key indicators of drilling operation performance. The estimation of ROP in drilling engineering is very important in terms of more accurate assessment of drilling time which affects operation costs. Hence, estimation of a ROP model using operational and environmental parameters is crucial. For this purpose, firstly physical and mechanical properties of rock were derived from well logs. Correlation between the pair data were determined to find influential parameters on ROP. A new ROP model has been developed in one of the Azadegan oil field wells in southwest of Iran. The model has been simulated using Multiple Nonlinear Regression (MNR) and Artificial Neural Network (ANN). By adding the rock properties, the estimation of the models were precisely improved. The results of simulation using MNR and ANN methods showed correlation coefficients of 0.62 and 0.87, respectively. It was concluded that the performance of ANN model in ROP prediction is fairly better than MNR method.

Published: March 2017

Abstract
The problem of cooperation of powered roof support with the floor in the aspect of shaping its design is presented. From the analysis of the simplifying assumptions considered so far in the methods for determination of roof support’s base pressure on the floor, it results that they are not satisfied in the case of bases of the catamaran type, commonly used in currently manufactured roof supports. Model of cooperation of the base lying on the floor, prepared by the finite elements method is described and the results of computer simulation of the base action on the floor are given. Considering the results of numerical analyses, the factors influencing the pressure distribution of the base on the floor as well as its maximal value, have been identified.

Abstract
All around the globe suicide is an increasing health problem because of the devastating effects that the loss of lives it leaves behind. There are instances when a suicide attempt is but a warning signal, a kind of cry for help, but in some cases its drastic character excludes any doubt about its annihilative aim. There are such situations in which the individuals opting for suicide try to limit the risk of failing in such act to the minimum.
This article presents three suicide cases autopsied at the Bistrita-Nasaud County Forensic Division tht share the fact that they use multiple, converging methods of self-destruction: the first case is that of an elderly man who, after ingesting a significant amount of thiocarbamide pesticides, hangs himself, the second case is that of a policeman in the rural area who, upon an acute alcohol intoxication, shoots himself six bullets in the stomach with the pistol provided, and the third case is of an unknown male citizen who, after sheltering under a bridge, drinks about 600 ml of petrol, then splashed himself with petrol and sets himself on fire.

Abstract
The study was aimed to identify the role of surgical treatment of tibial plateau fractures, its functional outcome and complications. Demographic data for the patients and details of current clinical and radiological follow-up findings were obtained to assess range of motion, clinical stability, alignment of the knee, and posttraumatic arthrosis (Kellgren/Lawrence score). 64 cases of tibial plateau fractures treated by different surgical methods and variuos implants type were studied from 2013 to 2015 and followed-up for minimum period of 6 months. The systematisation of the casuitry was made using Schatzker and AO classifications. The treatment methods consist of: percutaneous cannulated cancellous screws, ORIF with buttress plate with or without bone grafting, locking or nonlocking plates, external fixator. As complications we found: redepression 4 case, malunion 2 cases, knee stiffness 9, wound dehiscence in 1 cases and non-union or infection in none of our cases. The average flexion of the injured knee was significantly lower in comparison with the contralateral side (124.9°/135.2°). Knee stability did not differ statistically significantly. There were no signs of posttraumatic arthrosis in 45% of cases, mild signs in 30%, clear signs in 18%, and severe signs in 7%. As conclusion we found that surgical management of tibial plateau fractures will give excellent anatomical reduction and rigid fixation to restore articular congruity, facilitate early motion and reduce arthrosis risk and hence to achieve optimal knee function. The choice of optimal surgical methods, proper approach and implant is made in relation to fracture type according Schatzker and AO classification.

Abstract
The rapid implementation of stents in standard practice and expansion of the indication for their utilization also introduced a new problem: in-stent restenosis. Management of patients with restenosis after stent implantation is still considered an important clinical problem. Although balloon angioplasty is still one of the prefered strategies that provide satisfactory results and a low incidence of complication, repeat stenting with “drug eluting” stents or “drug balloon” angioplasty become a very atractive methods of treatment for selected lesions and patients.
Interactions of daylength, temperature and nutrients affect thresholds for life stage transitions in the kelp Laminaria digitata (Phaeophyceae)

Published: March 2017

AbstractKelp beds worldwide are under pressure from ongoing climate and environmental change. Along European coastlines increases in seawater temperature and changes in nutrient conditions occur where upwelling events are disrupted and also along eutrophicated coasts. In addition, seaweed responses to change may interact with seasonal daylength cycles. We performed a factorial experiment to examine the combined effects of seawater temperatures, nutrient regimes and photoperiod (long and short days) in order to better understand how latitudinal or seasonal differences in daylengths affect the sensitivity of transient microscopic kelp stages of
Community livelihood activities as key determinants for community based conservation of wetlands in Uganda
Authors: Barakagira Alex , de Wit Anton H. 
Published: March 2017

Abstract
Community-based Conservation (CBC) has been regarded as one of the most appropriate approaches to the sustainable utilization and conservation of natural resources. Wetlands are believed to provide attributes, functions, and services that positively affect the daily livelihoods of members of the local community. Bearing in mind the incentives wetlands provide, if community members are not involved in the activities aimed at the management and conservation of wetlands then they result in being degraded. This study was initiated to explore how community livelihood activities influence CBC of wetlands in Uganda. A cross-sectional research design was used to collect qualitative and quantitative data. A questionnaire survey was conducted among four hundred households to collect information concerning community livelihood activities taking place in wetlands. Additionally, more information was obtained from National Environment Management Authority, and Wetlands Management Department staff using another non-structured questionnaire. Key informant interviews and direct observations were also used to collect data. Overall, the gathering of materials for building and crafts, fuel wood collection, clay and sand mining and practicing agriculture in wetlands are some of the reasons that have caused wetland degradation. Low levels of awareness, unclear ownership of wetlands and inadequate funding has not enabled Agencies responsible for implementing the Policies and Laws aimed for protecting and conserving wetlands from being degraded. Therefore, these above mentioned problems must be addressed in order for wetland resources to be sustainably utilized and conserved by members of the local community.
Is China’s target of a 40-45% reduction in carbon dioxide emission plausible?
Authors: Bosupeng Mpho 
Published: March 2017

Abstract
In the early days of industrialisation, economists believed that the ramifications of economic growth will far outweigh the potential damage to the environment. Today the concern is the rising magnitude of emissions. Many economies are under immense pressure to reduce carbon dioxide emissions. Carbon taxation and absorption technologies seem to be the main mechanisms controlling emissions in different nations. China proposed her target of reducing carbon dioxide emissions by 40-45% by 2025. The purpose of this study is to determine if China’s ambition of reducing its carbon dioxide emissions is feasible. This investigation also examines the potential effects of China's emissions on the economic growth of other countries. The study demonstrates that China’s target may not only reduce her output, but may also adversely affect the economic growth of others. This article further reveals that unemployment in China is likely to soar during the reduction in emissions and energy consumption. Additionally, this paper evaluates the effects of green taxation on carbon dioxide emissions. In conclusion, there is a possibility that China may reach her emissions target by 2025. However, the country faces a dilemma between economic growth and environmental preservation. It is recommended that China should explore techniques which will reduce emissions but not impinge negatively on economic growth.

Published: March 2017

Abstract
Thermal instability in a horizontal layer of Couple-stress nanofluid in a porous medium is investigated. Darcy model is used for porous medium. The model used for nanofluid incorporates the effect of Brownian diffusion and thermophoresis. The flux of volume fraction of nanoparticle is taken to be zero on the isothermal boundaries. Normal mode analysis and perturbation method is employed to solve the eigenvalue problem with the Rayleigh number as eigenvalue. Oscillatory convection cannot occur for the problem. The effects of Couple-stress parameter, Lewis number, modified diffusivity ratio, concentration Rayleigh number and porosity on stationary convection are shown both analytically and graphically.
Inductor Machines with Longitudinally-Transversal Comb-Wise Tooth Zone
Authors: Serebryakov A. , Levin N. , Kamolins E. , Mileiko M. 
Published: March 2017

Abstract
The method considered in the present paper concerns the operational efficiency of the inductor electric machine, which can be improved by placing on the stator and rotor teeth the combs combined from differently shaped teeth and slots. The use on the inductor electric machine stator and rotor teeth of combs as a combination of differently shaped hills (teeth) and valleys (slots) allows raising the specific power of the machine. This effect is determined by the chosen type of a comb element as well as by technological possibilities of the manufacturer. The proposed method could be used moderately in the inductor machines with longitudinally-transversal combing.
The Analysis of Non-Newtonian Vibro-Impact Processes in Tube Constructions and Systems with Parallel Impact Pairs
Authors: Krupenin V. L. , Viba J. 
Published: March 2017

Abstract
The present paper studies the problems of creation of techniques for the analysis of vibro-impact processes in systems with a large number of impact pairs. The used method of singularisation allows refusing from the ideas of the momentary impact and considering interaction hypotheses, which are more realistic than Newtonian ones. We consider the features of synchronous modes of movements of the clap type in systems with parallel impact elements as well as in tubes colliding with intermediate supports. Such modes are most dangerous in terms of the vibration wear of structural elements. The examples of calculation are given for specific designs.
