Opis:
Introduction. Tibial plateau fractures are common injuries that require anatomic reduction to obtain the best functional results. Advances in mechanization and the acceleration of travel has been accompanied by an increase in the number and severity of fractures, and those of the tibial plateau are not an exception. This fracture constitutes approximately 1% of all fractures. The primary goal in the management of proximal tibial articular fracture is a stable, congruous, pain-free, mobile joint. Objectives. To study the technique, results, and complications of percutaneous cancellous screw fixation for tibial plateau fractures. Materials and method. 22 patients treated with percutaneous screw fixation were followed-up for a period of 18 months and their functional outcome assessed according to the Modified Delamarter functional scoring system. Results. According to the Modified Delamarter functional scoring system, a 91% – excellent to satisfactory result was achieved, and 9% poor results due to non-union at the fracture site. Conclusions. Closed reduction and percutaneous screw fixation for tibial plateau fractures is minimally invasive. It reduces the length of hospital stay and costs, enables early mobilization with minimal instrumentation, and achieves satisfactory outcomes.

Opis:
Owing to the rising costs of chemical fertilizers and the growing environmental concerns, there is an ever increasing interest in the role of soil microorganisms in crop nutrition and soil fertility restoration. A field study was therefore conducted at Pawe Agricultural Research Center during 2010 main cropping season to determine the influence of Bradyrhizobium japonicum inoculation and N and P fertilizers application on nodulation, yield and yield attributes of soybean. Three levels of N (0, 11.5 and 23 kg N ha-1); three levels of P (0, 23 and 46 kg P2O5 ha-1) with two levels of Rhizobium were arranged in RCBD in factorial combinations with three replications. Nodule number, nodule fresh and dry weights, plant height, number of pods and seeds per plant, 100 seeds weight and grain yield responded significantly to the interaction effects of B. japonicum inoculation and application of N and P fertilizers but nodule volume, seed and biomass yields, and harvest index were significantly affected by the main effects of any one or more of the factors and interaction of any two of the factors. The maximum numbers of nodules of 80.26, fresh and dry weights of 3.77 and 0.99 gm./plant respectively; were measured by combined effect of 11.5 kg N/ha, 46 kg P2O5/ha and B. japonicum. Similarly the highest nodule volume of 3.53 and 3.27 ml/plant were measured after applications of 46 kg P2O5/ha with B. japonicum and with 11.5 kg N/ha respectively. The highest plant heights of 79.26 cm followed by 76.94 cm were measured by application of 46 kg P2O5/ha with B. japonicum and 46 kg P2O5/ha itself respectively. Seed yield significantly increased to 11.91 gm /plant and 15.97 gm /plant following application of B. japonicum alone and 46 kg P2O5/ha with B. japonicum respectively. Applied 23 kg/ha brought the highest plant biomass of 27.25 gm/plant. Inoculation with 46 kg P2O5/ha and the combined effects of 11.5 kg N/ha, 46 kg P2O5/ha and B. japonicum resulted 73.93 and 80.66 number of pods per plant respectively. The maximum 100.60 numbers of seeds per plant were counted during inoculation of B. japonicum with 46 kg P2O5/ha. The maximum 100-seed weight of 16.96 gm and grain yield of 3151.88 kg/ha were produced by combined application of 11.5 kg N/ha, 46 kg P2O5/ha and B. japonicum. Each nodule attributes were significantly and positively correlated each other and with each yield and yield attributes. The results showed that growth and yield potential of soybean and an increase N2 fixing can be achieved by using B. japonicum and P fertilizer with reduced level of N as starter fertilizer.

Pragmatic phraseology has long been perceived as a marginal linguistic object. As a result, moves from total marginality to enlightenment by several more or less recent linguistic theories have occurred. This article proposes an examination of the syntactic, morphological and semantic compositional criteria of pragmatemes used to express an emotion. We also reflect on the interaction between co-text and context in the construction of the meaning of a ‘pragmatème’ of affect. We observe the influence of the elements of textual nature namely the co-text and the environment of the context on the meaning of a ‘pragmatèmes’.

Opis:
The fucosyltransferase NodZ is involved in the biosynthesis of the nodulation factor in nitrogen-fixing symbiotic bacteria. It catalyzes α1,6 transfer of l-fucose from GDP-fucose to the reducing residue of the synthesized Nod oligosaccharide. We present the structure of the NodZ protein from Bradyrhizobium expressed in Escherichia coli and crystallized in the presence of phosphate ions in two crystal forms. The enzyme is arranged into two domains of nearly equal size. Although NodZ falls in one broad class (GT-B) with other two-domain glycosyltransferases, the topology of its domains deviates from the canonical Rossmann fold, with particularly high distortions in the N-terminal domain. Mutational data combined with structural and sequence alignments indicate residues of potential importance in GDP-fucose binding or in the catalytic mechanism. They are all clustered in three conserved sequence motifs located in the C-terminal domain.

Opis:
Testing usability with eye-tracking enables to understand a new dimension of user interaction. We can research areas that are most interesting for users and what behaviour patterns cause it. It is possible to identify page elements that attract attention and to which the user is blind. The eye-tracker device is very accurate, it can measure up to 120 times per second the position of the eye on the screen. Using research data it is possible to draw gaze plots report and heat map chart for further analysis. In my opinion the greatest challenge for performing eye-tracking research is to use appropriate methodology, such as set exposure time, fixation length, recruit representatives group, set up relaxing testing condition for users to react in a natural way.

Opis:
In this paper, the Bayesian model for bimodal sensory information fusion is presented. It is a simple and biological plausible model used to model the sensory fusion in human’s brain. It is adopted into humanoid robot to fuse the spatial information gained from analyzing auditory and visual input, aiming to increase the accuracy of object localization. Bayesian fusion model requires prior knowledge on weights for sensory systems. These weights can be determined based on standard deviation (SD) of unimodal localization error obtained in experiments. The performance of auditory and visual localization was tested under two conditions: fixation and saccade. The experiment result shows that Bayesian model did improve the accuracy of object localization. However, the fused position of the object is not accurate when both of the sensory systems were bias towards the same direction.

Opis:
Two early nodulin 40 (enod40) genes, ENOD40-1, the shortest legume ENOD40 gene, and ENOD40-2, were isolated from Lupinus luteus, a legume with indeterminate nodules. Both genes were expressed at similar levels during symbiosis with nitrogen-fixing bacteria. ENOD40 phylogeny clustered the L. luteus genes with legumes forming determinate nodules and revealed peptide similarities. The ENOD40-1 small ORF A fused to a reporter gene was efficiently expressed in plant cells, indicating that the start codon is recognized for translation. The ENOD40-1 RNA structure predicted based on Pb(II)-induced cleavage and modeling revealed four structurally conserved domains, an absence of domain 4 characteristic for legumes of indeterminate nodules, and interactions between the conserved region I and a region located upstream of domain 6. Domain 2 contains Mg(II) ion binding sites essential for organizing RNA secondary structure. The differences between L. luteus and Glycine max ENOD40 RNA models suggest the possibility of a switch between two structural states of ENOD40 transcript.

Opis:
Pojęcie „utwór naukowy” jest w obowiązującej ustawie o prawie autorskim i prawach pokrewnych wymienione jako jeden z rodzajów przedmiotów ochrony prawa autorskiego. Spełniać on powinien ogólne przesłanki utworu, a mianowicie mieć twórczy i indywidualny charakter. Utwór korzysta z ochrony ze względu na zawarte w nim oryginalne wartości. Stanowi organiczną jedność elementów twórczych i zaczerpniętych z otaczającej twórcę rzeczywistości, w tym z dotychczasowego dorobku twórczego. Utwór naukowy odróżnić należy od ustaleń naukowych, które w utworze naukowym są przedmiotem oryginalnej (twórczej) i indywidualnej pracy, tzn. stanowiącej wynik ujęcia wyrażającego osobistą projekcję wyobraźni twórcy i wskutek tego niepowtarzalną w zakresie dokonanego przez twórcę wyboru oryginalnego ujęcia sposobu przedstawienia i wyrażenia zjawisk, ich cech i zachodzących pomiędzy nimi relacji jako dobra w stosunku do utworu transcendentnego oraz od badań naukowych jako procesu, mającego na celu dokonanie ustalenia naukowego. Udział w dokonaniu ustaleń naukowych stanowi tytuł do ochrony jako dóbr osobistych i nie przesądza autorstwa utworu naukowego, umożliwiającego ich poznanie, w zakresie ich oryginalnego doboru, ujęcia, przedstawienia i wyrażenia. Charakter utworu jako naukowego nie przesądza środków użytych do ustalenia składającego się na ten utwór treści. Pojęcia „utwór naukowy”, „artystyczny”, „popularnonaukowy” nie stanowią pojęć dychotomicznych. O naukowym charakterze decyduje cel poznawczy prezentowania w jakiejkolwiek formie i jakimikolwiek środkami zjawisk ich cech, właściwości oraz występujących pomiędzy nimi zależności.
The term „scientific work” is the term used by the existing Act on copyright and related rights of February 4, 1994 (Law Journal of 2016, item 666 as amended) and it constitutes one among a number of types of works protected by copyright. The existing Copyright Act is not defining the meaning, of „scientific work”. The basic significance has therefore distinguishing scientific work from research in the meaning of process leading to certain findings, based on using specific methodology leading to these findings and scientific findings themselves, as personal rights, constituting in the wide meaning of this word creativity (referred to in art. 23 of the Civil Code) of persons, whose this particular finding is coming from. The basic issue is the necessity to distinguish scientific work as an object of copyright protection, that is an intangible good of a specific characteristics, distinctiveness from specific tangible good, referred to by scientific work, which constitutes transcendental good in relation to the work. Also computer programs can be scientific works. Scientific works do not however encompass inventions, discoveries, researches and scientific projects. The qualification of a work as a scientific work does not justify the limitation to express the work in a certain form as for example literary work. A scientific work can be scientific article or scientific monograph, but also scheme expressed by visual means or photography created on the basis of scenario tending towards disclosing the essence or features of the occurance examined for a certain purpose. The most important is to distinguish the process the research is being conducted by, including its scenario and result, from scientific work, which constitutes the report about the certain occurance, its features or relations, in particular methodological assumptions or results fixed in any manner, subordinated to cognitive function, that is allowing to get acquitained with content and methodology being reported on, which resulted with formulating certain conclusions and meaning evaluated, paying special attention to certain elements. In the consequence, the author of the research and the author of the report thereof, does not necessarily have to be the same person. A separate issue is quite floating border line between artistic, scientific and popular science work. A work is always a relation, expression of individual vision of a certain issue, item, occurance, process, its features and dependences. Formal measures used in the work are only tools to express the projection of authors imagination. The distinguishing feature is the method of expressing of certain transcendental goods within the work, for the purpose of learning, subordinated to this purpose. The discriminant element of scientific work is, within its cognitive purpose, the method of conceptualization, disquisition and maintaining specific level of explicitness and precision in formulating judgments and their justifications. Scientific work is an object of copyright protection, where basing on the method of selection, presentation, expression of specified thesis and their substantations assumed by the author, an original projection of author’s vision as to the existance of specific occurances, goods, their features or reliances, transcendent in relation to the scientific work occures, regardless of means of expression, which have been used.

Jarosite residues, which are generated in a zinc production plant by a hydrometallurgical process, contain a large amount of valuable metal components. In this study, a method was proposed for the recovery of lead, zinc and iron from the residues and simultaneous sulfur fixation through direct reduction followed by magnetic separation. The influences of the roasting temperature, roasting time and the concentration of SO2 gas in the direct reduction process were researched in detail. Results showed that the volatilization rates of lead, zinc and sulfur were 96.97%, 99.89% and 1.09%, respectively, and the iron metallization rate was 91.97% under optimal reduction conditions; roasting temperature 1523 K for 60 min. The magnetic concentrate with the iron content of 90.59% and recovery rate of 50.87% was obtained from the optimal reduction product by grinding and magnetic separation. The optimum fineness for separation 96.56% less than 37 μm accounted with magnetic field strength 24 kA/m. The theoretical analysis was carried out by thermodynamics, X-ray powder diffraction, gas analysis and scanning electron microscopy.

Opis:
Nitrogen is one of the key components of plant production and the nitrogen requirement of the plant supplied either by mineral nitrogen applications or by biological nitrogen fixation. Although the atmosphere contain huge amount of N2, plants are not able to use that as a nitrogen source. Immediately usable forms of nitrogen are nitrate (NO3-) or ammonium (NH4+). The bonds between two nitrogen atoms are quite strong thus, reducing N2 gas to mineral nitrogen forms needs considerable high amount of energy. However, in biological life, microorganisms may convert N2 to mineral nitrogen sources in ambient temperature and pressure; therefore, biological nitrogen fixation is both environmental friendly and sustainable. Industrial nitrogen fixation and mineral fertilization leads both environmental pollution and economic impact. In this research, the effects of humic+fulvic acid (HFA) on nitrogen fixation were evaluated. For this purpose, a pot experiment in controlled environment was carried out. Peanut seeds were sawn in the hole prepared after dual application of HFA doses and rhizobium bacteria. Two times sampling was realized, one in the flowering and the other in harvest time. Results revealed that HFA application was effective on biologic nitrogen fixation; however, increasing HFA doses were adversely influenced determined parameters. Due to the soybean was cultivated as a forecrop at the field where the experimental soil is collected, nodulation was observed even at non-inoculated pots. Nevertheless, the higher values obtained from inoculated plants. Based on the results presented in the paper, HFA was positively effective on a number of parameters evaluated, yet the lower doses should be recommended.

Background. To evaluate the outcomes of transiliac cerclage with Dall-Miles cable in the internal fixation of the posterior complex in unstable pelvic ring fractures between January 1995 and December 2014. Material and methods. A study of 42 men injured at work with an average age of 35.2 years (range, 23 to 61) was conducted. The mechanisms of injury were traffic accidents in 25 cases (59.5%), crushing accidents in 12 cases (28.6%), and fall from height in 5 cases (11.9%). Thirty-six cases were polytraumatized patients (85.7%). The patients were evaluated using Majeed’s functional score and Matta’s radiological criteria. Results. The average follow-up time was 135.8 ± 45.6 months. The clinical outcomes were excellent in 17 cases (40.5%), good in 19 cases (45.2%), fair in 5 cases (11.9%), and poor in 1 case (2.4%). The radiological outcomes were satisfactory in 32 cases (76.2%) and unsatisfactory in 10 cases (23.8%). All fractures were healed. The sequelae were 3 cases (7.2%) of lower limb dysmetria and 3 cases (7.2%) of chronic neuropathic pain. Conclusion. The internal fixation of the sacroiliac complex by Dall-Miles cable cerclage reinforced with small fragment plates should be considered as an alternative method for minimally invasive osteosynthesis in selected cases of unstable pelvic ring fractures.

Opis:
Bacteria belonging to the genus Azotobacter are microorganisms commonly found in various soils all over the world and capable of fixing atmospheric nitrogen. The biological nitrogen fixation (BNF) process annually supplies approximately140–170 million tons of this element to the nitrogen cycle, which is of great importance from an ecological and practical point of view. Although the efficiency of atmospheric nitrogen fixation by Azotobacter spp. is relatively high and amounts to 20 mg N per1 g of glucose used, these bacteria are sensitive to various environmental factors, including soil reaction, contents of organic matter, soil humidity or nutrient content, and their abundance in soils is small. These bacteria secrete numerous biologically active substances into the soil environment, which have a beneficial effect on the development of plants, which from the ecological point of view plays an important role in the functioning of agricultural ecosystems. An additional advantage of bacteria belonging to the genus Azotobacter, which speaks for their use in agriculture, is the ability to produce antifungal and solubilization of insoluble phosphates. Research on Azotobacter spp. proves that the concentration of hydrogen ions (pH) is a significant factor which determines the presence of this group of bacteria in the soil environment. Many other soil properties have a large impact on the presence and development of this important agricultural group of bacteria. The aim of the work was to systematize the knowledge on the known occurrence conditions and ecological relationships and interactions between environmental factors and the presence and abundance of Azotobacter bacteria in soils.
