The Influence of the Hardening Curve Profile on the Drawing Force of a Bar
Authors: Baranov Georgy L.
Published: October 2018

The effect of the hardening curve profile of a workpiece material on the drawing force of the bar under the conditions of planar deformation is studied. Dependencies for determining the stress in the crimping part of the dies were obtained taking into account the profile and parameters of the hardening curve. A comparison of these dependencies with known formulas for the calculation of drawing stresses is provided. It is shown that for the exponent of the hardening curve n ≤1 and taking into account contact friction, the use of the arithmetic mean yield point value leads to a decrease in the calculated drawing stress value. The difference in the results of the calculation increases with a decrease in the exponent n and an increase in the friction coefficient, reaching 20% ​​or more at n≤0.35.

Authors: Kuzeev I.R.
Published: October 2018

High-carbon substances and carbon itself are important structure-forming elements. Of special interest are substances obtained from petroleum feedstock by means of high-temperature treatment. Such substances could include bitumen, pitch, coke, fullerenes, carbon nanotubes and some composition materials. The present article provides a literature review, devoted to structuring in complex multi-component systems, which demonstrated to obtain quasi-crystalline substances in macroscale. In petroleum disperse systems the regulating factor leading to the formation of hierarchy structures is presence in the medium of asphaltenes exerting paramagnetic properties. It was experimentally showed that change of the equivalence ratio of such components as core, salvation shell, and dispersion medium leads to intentional obtainment of various configurations of quasi-crystalline systems. Understanding of macrostructures formation mechanisms under condition of change of medium properties at nanolevel allows constructing new carbon-based constructional materials.

Authors: Kolmachikhina Elvira B. , Ryzhkova E.A. , Dmitrieva D.V.
Published: October 2018

This paper is describing an investigation of surfactants influence on zinc sulfide wetting by non-polar liquids and sphalerite concentrates pressure leaching parameters. Zinc sulfide preferential wettability by oil was tested in presence anionic surfactants with different chemical structures. Interfacial tension was determinated by the maximum liquid drop volume method. It allows to determine surfactant potential effectivity on pressure leaching of sphalerite concentrate. It is found that SDBS decreases zinc sulfide wettability by non-polar liquids in a greater degree than SDS and Ls. Combined addition of Ls and SDBS allowed to receive residues with optimal coarseness, eliminate pellet formation and increase zinc extraction.
Magnetic Petroleum Sorbent Based on Waste Kieselghur Sludge from Oil Extraction Industry for Removing Petroleum Products from Water Surface
Authors: Starostina Irina V. , Nikitina A.E. , Porozhnyuk E.V.
Published: October 2018

The method of obtaining magnetic petroleum sorbent for petroleum products spills cleanup from water surface, based on the mixture of waste kieselghur sludge from oil extraction industry and a ferromagnetic component - the finely-dispersed iron-ore concentrate (magnetite), has been suggested. It has been demonstrated that after the waste kieselghur sludge thermal modification in the temperature interval 430-500°С the burn-out of the organic matter is not complete – there remain the wax fractions of wax-like substances, contained in it. The obtained material becomes hydrophobic and oleophilic. The introduction of magnetite in amount of 10% provides the maximum oil-absorbing capacity of the petroleum sorbent – 3.05 g/g without reducing its hydrophobic properties. The value of the wetting angle amounts to 150°, and the water absorption is very low – no more than 2.1%. The optimal temperature of the magnetic petroleum sorbent production is 450°С. The obtained material in its petroleum-saturated state is highly buoyant within 24-120 hours, which provides enough time to clean up the water surface from petroleum products and to collect the sorbent.

Authors: Yur'ev Boris P. , Dudko Vyacheslav A. , Biakova M.
Published: October 2018

One of the advanced and unconventional forms of energy, i.e. super high frequency field energy, has been studied. Advantages of super high frequency field application have been demonstrated, in comparison with the other forms of energy. It has been found out, that the sources of super high frequency heating (SHF-heating) allow obtaining the concentrate free of combustion products, as well as reducing pollution of the environment. Drying of Olenegorsk fine grinding masterbatch (Olenegorsk Mining and Processing Plant) proves the value of these advantages and makes it feasible to adopt this process during preparation of the iron-ore pellets for metallurgical treatment. It has been shown that the intensity of drying in the SHF-field is vastly superior to the one achieved in conventional convection units, due to volumetric nature of the heating and more favourable conditions for heat-and mass-exchanging processes in the bed. The obtained results may be used for the development of the design of units for drying fine-grained materials in the SHF-fields.
Efficient Assessment of Physico-Chemical Properties of the Cryolite Melts for Research on the Improvement of Low-Temperature Aluminum Electrolysis
Authors: Lebedev V.A. , Shoppert Andrey A.
Published: October 2018

Modern aluminum electrolysis in cryolite-alumina melts is energy-intensive, inefficient and environmentally hazardous production. Addressing these significant shortcomings, the technology of low-temperature electrolyte is directed. The basis of low-temperature electrolysis is potassium cryolite, which results in high magnitude and rate of dissolution of alumina. Additive of sodium and lithium fluorides provide the necessary conductivity. Experimental investigation of these properties is extremely time consuming. In this work, as a parameter, which will allow to characterize effectively and rapidly the complexing ability of cryolite melts, the ratio of cationic ion power of Al3+ to the total power of the other cations of the melt is proposed. Regression analyses of the known experimental data establish the existence with a high level of reliability (R2=0.966-0.995) of a directly proportional dependence of this parameter on solubility of alumina and electrical conductivity of cryolite melts.

Authors: Polygalov S.E. , Mastugin S.A. , Shadrina E.A.
Published: October 2018

The work is devoted to the study of the possibilities of minimizing the release of nitrogen oxides during the dissolution of silver in nitric acid solutions during refining of the gold and silver alloy. Using a rotating disk, the maximum concentration of nitric acid is determined, at which the oxidation potential of the system is insufficient for the oxidation of silver. It has been established that at a temperature of 363 K and a concentration of HNO3 = 50 g/l, the dissolution rate of silver does not exceed 0.00022∙10-5 mol/(cm2∙s), and such conditions can be considered as background for an environmentally friendly process. To initiate dissolution, hydrogen peroxide was used as an alternative oxidizing agent. As a criterion for the rational use of the oxidant and the ecological purity of the process, the excess pressure over the solution was evaluated. The influence of the initial and current composition of the solution, temperature, and conditions of oxidant supply to the reactor on the kinetics of the target process was studied. It is shown that at a silver dissolution rate of 2.7∙10-6 mol/(cm2∙s), no release of nitrogen oxides was observed.

Published: October 2018

The mathematical model of a wood polymeric sand composite has been developed, which allows studying the thermal insulation properties of a composite material, taking into account the ratio of wood filler to the other components, the method for obtaining samples, and the type of wood filler. The technique of modeling and analysis of the obtained results is given. By mathematical modeling it was established that the wood polymeric sand composite has thermal insulation properties 2-3 times better than that of construction materials based on concrete. Construction materials based on the developed composite have a higher heat capacity than pure wood, which allows them to better maintain the constancy of the temperature inside the premises with significant daily fluctuations in the external temperature. A series of practical tests were conducted to evaluate the reliability of the results obtained. The discrepancy between theoretical and practical results does not exceed 5%.

Part II: Examining Stakeholder Perceptions of the Postprofessional Clinical Doctoral Degree in Athletic Training
Authors: Bliven Kellie C. Huxel , Potteiger Kelly , Baker Russell T. , Pitney William A.
Published: October 2018

Context:

As health care education evolves, so do the required educational degree levels. In athletic training, the master's degree has traditionally represented the advanced degree option, but clinical doctoral education is relatively new and not well understood.

Objective:

To explore stakeholders' perceptions of the postprofessional clinical doctorate in athletic training (DAT).

Design:

Population survey.

Patients or Other Participants:

Survey participants included 254 faculty members, 150 administrators, 334 clinicians, and 131 employers.

Intervention(s):

Four surveys designed to gauge perceptions of the DAT.

Main Outcome Measure(s):

Descriptive statistics were calculated to describe perceptions. Qualitative data from open-ended questions were analyzed inductively and organized into themes.

Results:

Faculty and administrators were more familiar with various degrees (71.8%–82.3%), whereas clinicians and employers indicated no or little (52.5%–58.0%) familiarity with clinical doctoral degrees. There was discord between faculty and administrators regarding the viability of the DAT as an alternative to the postprofessional master's degree. Faculty believed the DAT would help advance knowledge and clinical skills among practitioners. Administrators believed in increased education and clinical expertise of faculty, increased productivity, and an alternative avenue for hiring faculty for those with a DAT. Hiring concerns, research productivity, friction among degree holders, program expense, and lack of understanding of the degree were negative implications reported by administrators. Clinician interest in pursuing a DAT was divided (47.5% interested, 52.5% not interested). Reasons for pursuing the DAT included increased clinical ability, desire to transition to a faculty role, and advancement. Employers were divided as to whether they would hire a DAT. Employer concerns included lack of adequate compensation and lack of significant difference in clinician skills.

Conclusions:

Support for the DAT by all stakeholders exists. However, there are concerns and a general lack of understanding about the degree that should be addressed among all stakeholder groups.

Published: October 2018

Abstract. Arsenic (As) has long been recognized as a toxic element of
mainly anthropogenic origins, having adverse effects on human health.
However, there is insufficient understanding regarding As released into
atmosphere from biomass burning (BB). To this end, daily airborne As
concentrations in total particulate matter (TSP) were determined at Mount
Hehuan (24.16∘ N, 121.29∘ E, 3001 m a.s.l.), Taiwan from
September 2011 to September 2012. During the sampling period, As
concentrations varied from 0.02 to 5.9 ng m−3, with a mean value of 0.5±1.0 ng m−3. Significantly seasonal variations of As were found
over the subtropical free troposphere, and higher As concentrations were
observed in the southern (S) and southeastern (SE) Asian BB seasons (from January
to May). Principal component analysis (PCA) results showed that BB activities
seemed to be a major source of As during the S and SE Asian BB periods,
which were very distinct from the major source of coal-fired power plant during the
periods between July and December. Based on backward trajectory analyses and
WRF-Chem model simulations, we found that the high As concentrations during the BB
periods were attributed to the biomass burning activities over S Asia where
groundwater, soil and crops are severely contaminated by arsenic. A strong
correlation (r=0.73 p<0.05) between As and potassium ion
(K+, a chemical tracer of BB activities) in S Asian BB events also
supported this hypothesis. During the S Asian BB events, the high As ∕ Pb
ratios (>0.2) were also observed, indicating that burning crops
contaminated by lead arsenate might be a crucial candidate for high As
concentrations at Mount Hehuan. Nevertheless, the net influence of S Asian BB
activities on airborne As concentrations has been estimated by comparing the
differences of As concentrations on BB and non-BB days. On average, the
difference in As concentrations was 1.0 ng m−3, which accounted for 63 %
of the average As concentration on BB days. Moreover, a ratio of ΔAs∕ΔCO (∼0.00001) in the S Asian BB events was
obtained. Using this value, arsenic emissions from S Asian BB activities were
estimated to be 0.17 tons yr−1, resulting in high airborne As
concentrations over the subtropical free troposphere and impacting As cycles
on a regional scale in the S and SE Asian BB seasons.
SPECIALTY POLYMERS AND DYNAMICALLY VULCANIZED ALLOYS FOR ULTRA LOW AIR PERMEABILITY TIRE INNER LINERS
Authors: Ellul Maria D. , Hara Yuichi
Published: October 2018

Brominated poly(isobutylene-co-p-methylstyrene) specialty elastomers (Exxpro™) or BIMSM (ASTM name) are unique in their low permeability to air combined with a low glass transition temperature, Tg,, and a saturated backbone; making them a choice elastomer for applications requiring air barrier properties. This behavior derives from the geminal dimethyl groups on every other carbon of the polyisobutylene (PIB) backbone causing modification in the bond angles of these chains, allowing them to pack more closely than other saturated hydrocarbons. Dynamically vulcanized alloys (DVAs), also known as thermoplastic vulcanizates (ASTM 5046) of Exxpro™ elastomer and nylon thermoplastic (Exxcore™ DVA), also referred to as BIMSM-Nylon DVA, have much lower permeability to air than BIMSM. The challenge is to maintain the elastomeric nature of the material by having a major volume fraction of BIMSM rubber, while approaching the excellent air barrier characteristics of nylon at a lower volume fraction of the thermoplastic matrix than the dispersed rubber phase. This problem was solved by introducing a functional oligomer that chemically reacts with the nylon. BIMSM-Nylon DVAs consist of submicron sized domains of BIMSM elastomer of tailored molecular structure, in a matrix of nylon and a chemically bound oligomer viscosity modifier. Thus, a reasonable elastomeric modulus is achieved, and the key performance properties of superior air barrier as well as low temperature fatigue resistance are well satisfied. Tire inner liners are the focused end use of BIMSM-Nylon DVA, where the novel material characteristics are targeted to achieve excellent air impermeability, durability, and lightweighting. Optimal combination of these properties is expected to deliver improved performance and sustainable benefits such as fuel economy and lower tire maintenance costs.

Learner corpora—repositories of authentic texts produced by foreign/second language learners (Granger, 2009)—have widely been used in second language (L2) research due to authenticity and practical insight. This study involves a learner corpus of placement test essays to examine L2 students’ use of lexical bundles and explore their linguistic needs so that the learner corpus can be used as potential linguistic resources for L2 students with their perceived needs. 367 placement test essays from Chinese L2 students in a midwestern university were analyzed in the study. The results show the most frequent use of prepositional phrasal lexical bundles, less frequent use of discourse-organizing bundles, and frequent use of ‘I’ in stance bundles. This study revealed L2 students need to be aware of the use of discourse-organizing bundles for cohesion/logic in academic writing and implied the value of L2 students’ lexico-grammatical use as a resource and investment with pedagogical significance.
Probable Pathological Gambling Behaviors in Macau: Social Cognitive Theory Approach
Authors: Chan Sao U. , Dos Santos Luis Miguel
Published: October 2018

Probable pathological gambling is one of the significant social issues after the release of the exclusive and monopoly system of gambling licenses from one owner to three casino operating concessions and eventually six sub-concessions in Macau. As a result, some residents in Macau had addicted to gambling behaviors and eventually became probable pathological gamblers. In fact, why these individuals become probable pathological gamblers and how did they become probable pathological gamblers should be identified to enhance the current social policy and regulations to assist and provide support to these people. This study employed the Social Cognitive Theory to explore the lived experiences and opinions from three ex-probable pathological gambling people in Macau. The result of this study aimed to provide and attract the attention of the social welfare department, policy makers, social workers and counselors in the field of gambling addiction.
Holism, Field Theory, Systems Thinking, and Gestalt Consulting: How Each Informs the Other—Part 2, Practical Application
Authors: Stevenson Herb
Published: October 2018

Part 2 of this bipartite article draws on the theoretical underpinnings of Gestalt Consulting—phenomenology, existentialism, holism, field theory, and systems thinking—discussed in Part 1 to show how they overlap to create an expanded perspective for Gestalt consultants. Building on the concepts of cocreation of the field, the article also explores how the field enables the occurrence of parallel processes such as projective and introjective identification. Further, the article suggests that the integrating dynamics of holism, field theory, and systems thinking can support an identity-creating process that becomes the dyadic dynamic between client and consultant. Finally, Part 2 highlights the Gestalt application of these concepts through numerous examples of how to be a “Gestalt” consultant, and how to intervene within organizations. It provides insights on unconscious and habitualized behavioral patterns that prevent possible (or even necessary) shifts from emerging and reiterates the importance of “presence” as a critical ingredient of emergent change and awareness when consulting from a Gestalt perspective.
A Case of Animal and Domestic Abuse Initially Diagnosed as Legg-Calve-Perthes Disease
Authors: Roth Ira , Martin Janet
Published: October 2018

A 1 yr old castrated male shih tzu was evaluated for an acute right rear limb lameness and hyphema in the anterior chamber of the right eye. On initial examination, the dog was non-weight bearing on his right rear limb. Ophthalmic examination revealed a centrally located, superficial corneal ulcer in the right eye and blood in the anterior chamber. Radiographic findings of the pelvis and right rear were suggestive of avascular necrosis of the right femoral neck with resultant fracture and possible avascular necrosis of the left femoral neck. The dog presented 20 days later for evaluation of an acute left rear limb lameness. A left distal femur Salter-Harris type II fracture; a nondisplaced, healing right pubic fracture; and a healing right zygomatic arch transverse fracture were seen on radiographs. The dog’s initial injuries were attributed to a routine fall at home, and radiographic interpretation suggested that this was plausible. Subsequent patient visits, evaluation of additional injuries, and interviews with the owner indicated that both animal and domestic abuse had occurred. Veterinarians must be alert to recognize signs of animal abuse and must be aware of the connection between animal and domestic abuse.

Published: October 2018

Brachycephalic airway syndrome (BAS) is characterized by increased upper airway resistance due to conformational abnormalities occurring in brachycephalic dogs (BD). In this prospective study, we evaluated pulse oximetry (SpO2) and arterial blood gas values in 18 healthy BD and compared these values with those of 18 healthy mesocephalic and dolichocephalic dogs (MDD). All dogs were assigned a BAS score based on an owner questionnaire. Inclusion criteria included presentation to the hospital for a problem unrelated to the respiratory system and unremarkable blood analyses and physical examination. In awake dogs, SpO2 values were obtained from a minimum of two sites. Dogs were then sedated, and SpO2 values were obtained again concurrently with an arterial blood gas sample. The SpO2 values were significantly lower in BD compared with MDD, but there were no statistically significant differences between BD and MDD for any arterial blood gas parameters. Based on the BAS score, BD who were moderately BAS-affected (n = 5), had significantly lower arterial saturation of hemoglobin with oxygen values on arterial blood gas when compared with MDD (n = 18). Although BD had statistically lower SpO2 values than MDD, the mean SpO2 values for both groups were within the normal range.

Published: October 2018

A 1 yr old intact male miniature dachshund presented for posturing to urinate without voiding and nocturia. Physical examination revealed congenital reproductive abnormalities and a fluid-filled structure caudal to the urinary bladder. The dog was diagnosed with a prostatic cyst and underwent an exploratory laparotomy with an attempt to remove the cyst. Twelve weeks later, the dog returned with recurring clinical signs, and the cyst was found to have returned back to its original size. A second intact male miniature dachshund presented at 7 mo of age for stranguria. Physical examination revealed congenital reproductive abnormalities and a fluid-filled structure on rectal palpation, much like the first dog. The dog was diagnosed with a prostatic cyst and underwent an exploratory laparotomy. An attempt was made to close communication between the prostate and cyst. The dog re-presented 3 wk later for recurrence of clinical signs, and the prostatic cyst was found to have increased in size. Both dogs were euthanized because of recurrence of clinical signs. This report describes the presence of prostatic cysts in two young dogs with congenital abnormalities of the genital and reproductive tracts and the similarities seen in human boys diagnosed with prostatic utricles.

Timely identification of the risks and using appropriate preventive actions to reduce the probability and impact of their occurrence play a significant role in increasing organizational efficiency, improving product quality and satisfying customers. Developing a systematic and efficient mechanism is a prerequisite for properly identifying and assessing the supply chain risks and making correct decision. Failure Modes and Effects Analysis (FMEA) is a known engineering technique and risk assessment tool to define, identify, and eliminate potential failures and errors in the products, processes, projects, and services. In this paper, FMEA approach is combined with multi-criteria decision-making techniques to make a systematic mechanism for assessing supply chain risks and prioritizing candidate flour suppliers in Sahar bread industrial group. In the proposed model, Analytic Hierarchy Process (AHP) is used to determine the risk’s weights and VIKOR method is applied for assessing and ranking the suppliers. Results shew that among the identified risks, “cost risk group” with the weight "0.43" is the most important. Therefor the company officials have to adopt appropriate policies, carefully, to deal with this risk. Moreover, final evaluation of flour suppliers in the company indicates that according to all criteria, the fourth supplier achieves the highest priority and it is selected as the most qualified flour supplier for the company.

In this paper we propose a centralized web firewall system for web application security which will provide a new type of synchronized system, which has the ability to  detect  and prevent a variety of web application attacks for a wide range of hosts at the same time , using an centralized command and control system, the attacked client then sends the information to a centralized command and control server which will distribute the attack information to all of the integrated clients connected to it. The distributed information contains all of the attack information including the type of attack, the IP address of the attacker, and the time of attack. The process of receiving the attacker's information and distributing it through the centralized web firewall is done automatically and immediately at the time of the attack. And all of the receiving clients will take actions against the threat depending on the distributed information such as banning the IP address of the attacker. The main process aims to protect multiple clients from any possible attack from the same attacker or the same type of attack. The system has been implemented to protect a real web application. Experiments showed that the attacks has been successfully prevented on multiple hosts at the time.

This paper came to provide a centralized web firewall system that connect different web firewalls in order to detect and prevent different types of web attacks and work as a fully integrated system with the different clients.

Anàlisi crítica d’aplicacions de lectura per a infants: paràmetres i indicadors
Authors: Peris Bixquert Maria
Published: October 2018

Les aplicacions de lectura digital infantil han evolucionat considerablement al llarg dels últims anys. Tanmateix, segueixen sent les grans oblidades en informes i estadístiques sobre la producció editorial i més encara dins del sector digital, cosa que origina un fenomen d’infoxicació en què el mediador es troba amb pocs criteris que faciliten la selecció d’aquest nou tipus de continguts. Aquesta investigació presenta els resultats de l’anàlisi de tretze aplicacions de lectura en les seues dimensions de forma i contingut. Alhora, s’hi observen trets com ara el mode d’adquisició, la privacitat, l’organització de continguts o la personalització. Finalment, reflexionarem sobre l’adequació dels criteris, atès que l’anàlisi de les tretze aplicacions ha mostrat com els paràmetres no analitzen amb la profunditat exigida el grau de plasticitat que poden arribar a tenir-ne les aplicacions i la facilitat per a esdevenir literatura digital.

La investigació que es presenta és l’estudi de cas d’un alumne intern d’origen marroquí d’un centre penitenciari de l’àrea metropolitana de Barcelona en el marc del projecte europeu KA2 StrategicPartnershipRiUscire. Els primers resultats del projecte evidencien la diversitat cultural i el plurilingüisme presents en el context penitenciari i la necessitat de millorar la competència intercultural i la competència lingüística dels alumnes interns per tal de contribuir a la seva reinserció social i laboral. El present estudi pretén indagar en el repertori i els usos lingüístics del jove i conèixer com valora la seva competència lingüística en les diferents llengües així com les actituds que manifesta entorn a les llengües del seu repertori lingüístic. La recerca adopta una metodologia qualitativa de caràcter exploratori i ha consistit en analitzar una entrevista semiestructurada utilitzant el mètode de l'anàlisi del discurs tenint en compte què diu l'entrevistat i com ho diu.
Essential oil yield and yield components of basil (Ocimum basilicum L.) as affected by genotype and intrarow spacing at Jimma, SW Ethiopia

Basil is an aromatic, medicinal, culinary, and multifunctional herb which is grown in different parts of Ethiopia. Although the oil distilled from the herb, as well as its herbal yields, are a crucial input in the pharmaceutical industry and for culinary purposes, the yield obtained is below its potential due to various challenges. Genotype and plant spacing are two of the factors which contribute to the low production of the crop. A field trial was conducted at Jimma University College of Agriculture and Veterinary Medicine (JUCAVM) in 2016 and 2017 to assess the effect of genotype and plant spacing on essential oil yield and other yield-related traits of this important herb. Four promising genotypes (BO-1, BO-3, BO-4, and BO-5) and three plant spacings (20, 30, and 40 cm) were studied in a 4 × 3 factorial design arranged as randomized complete blocks (RCBD) with three replications. Data on plant height, leaf area, number of primary branches, essential oil content and oil yield were collected and analyzed. The analysis of variance revealed that there were highly significant (p < 0.01) interaction effect of genotype with plant spacing for all parameters tested. The maximum essential oil yield (7.88 kg ha−1) was obtained from genotype BO-5 at 30 cm spacing, whilst the least (2.68 kg ha−1) was recorded from BO-1 at 40 cm spacing. The maximum oil content (101 mL g−1) was gained from BO-1 at 20 cm, but BO-3 at 30 cm spacing recorded the least oil content though there were no significant differences between the three treatment combinations. Further studies at different locations and seasons will be important to for future local recommendations.

The study aimed to determine the genetic variability in pitch pine (Pinus rigida Mill.) growing in the Niepołomice Forest (southern Poland). In the late nineteenth and early twentieth century, Adolf Cieślar of the Department of Forestry Research in Mariabrunn near Vienna, Austria established the experimental crops of pitch pine. During the study, 227 trees that grew in seven subunits were considered; an analysis of genetic polymorphism using the intersimple sequence repeats (ISSR) technique revealed that pitch pine is genetically variable. The average number of alleles at a given locus for all the pine trees was 1.649, while the effective number of alleles at the loci was 1.435. The value of expected heterozygosity was 0.254, while the percentage of polymorphic loci was 75.30%. The average genetic distance between the examined pines was 0.082. Principal coordinate analysis (PCoA) divided the examined pines into three groups, which was also confirmed by the structure-analysis results of the software STRUCTURE. The resulting division was mainly generated by the SR70 primer, which was indicated to be the primer that differentiated the examined populations of pitch pine. Affiliation of particular trees to selected groups was based on their occurrence in individual crops. This suggests a different origin of the seeds used to establish the research plots of pitch pine in the Niepołomice Forest.

Distal biceps tendon injuries are relatively rare. Standard treatment of complete tears and significant partial tears involves surgical anatomical reinsertion of the tendon at the radial tuberosity. Chronic injuries are usually managed with surgical tendon reconstruction using autografts or allografts. Conservative treatment is mostly limited to the elderly, individuals with a very low level of physical activity, patients with evident contraindications to surgical treat­ment, and cases of mild partial tendon tears. The selection of an optimum surgical technique and method of fixation remains controversial. The aim of this paper is to characterize distal biceps tendon injuries, discuss methods of their surgical treatment, and analyze postoperative physiotherapy regimens described in the literature. A literature review did not reveal any relationship between the surgical method and type of fixation used on the one hand and the period of immobilization, type of immobilization, or the postoperative physiotherapy regimen on the other.
