This paper presents the results of research in pure mature stands of sessile oak about 130 years old (100–120 years, VII age class), in the western part of the Republic of Srpska. On the basis of the data obtained from the research, models of growth in height of sessile oak trees were constructed. The research was carried out in acidophilic forests of sessile oak at three sites (Kozara - III site index, Motajica - II / III site index and Crni Vrh - IV site index). Three trees from the dominant tree category in each locality were selected for the construction of the model tree growth and for the analysis of height tree growth. The growth of the tree was reconstructed by the standard method of dendrometric analysis. For the approximation of height growth, the Prodan function was chosen from the analyzed functions. After regeneration in stands, the start time and the frequency of the thinning can be planned based on the constructed growth models in height. This will positively affect the vitality, stability and level of the production of stands.

Indium nitride (InN) is a highly promising material for high frequency electronics given itslow band gap and high electron mobility. The development of InN-based devices is hamperedby the limitations in depositing very thin InN films of high quality. We demonstrate growth ofhigh-structural-quality nanometer thin InN films on 4H-SiC by atomic layer deposition (ALD).High resolution X-ray diffraction and transmission electron microscopy show epitaxial growthand an atomically sharp interface between InN and 4H-SiC. The InN film is fully relaxed already after a few atomic layers and shows a very smooth morphology where the low surfaceroughness (0.14 nm) is found to reproduced sub-nanometer surface features of the substrate. Raman measurements show an asymmetric broadening caused by grains in the InN film. Our results show the potential of ALD to prepare high quality nanometer-thin InN films for subsequent formation of heterojunctions.

In this paper, we investigate the impact of air pollution on the content of photosintetic pigments, and the number, and the sizes of stoma’s cells for Tilia cordata Mill. and Tilia platyphyllos Scop., on three localities in the area of Banja Luka (Borik, Obilicevo i Paprikovac). The obtained results show that the number of stomas of Tilia platyphyllos in average is greater than that of Tilia cordata, particularly in leaves taken from the outer part of treetop comparing to that of the inner part. The dimensions of stomas are greater, in everege, of Tilia cordata than that of Tilia platyphyllos, due to the genetic’s conditions. Total content of the chlorophyll was varied from 1.656 to 5.616 mg/g, and the greater content during the season is established for Tilia cordata than for Tilia platyphyllos. The largest reduction of the number of stomas and photosynthetic pigments is established on the locality of Borik, where the highest concentration of ear pollution is noted. Our results show that changes in the number, the sizes of cells of stomas, and the content of photosynthetic pigments may serve as indicators of the resistance of the chosen species by ear pollution.

Background Mammograms contain information that predicts breast cancer risk. We recently discovered two novel mammogram-based breast cancer risk measures based on image brightness (Cirrocumulus) and texture (Cirrus). It is not known whether these measures improve risk prediction when fitted together, and with an established measure of mammographic density (Cumulus). Methods We used three studies consisting of: 168 interval cases and 498 matched controls; 422 screen-detected cases and 1,197 matched controls; and 354 younger-diagnosis cases and 944 frequency-matched controls. We conducted conditional and unconditional logistic regression analyses of individually- and frequency-matched studies, respectively. We reported risk gradients as change in odds ratio per standard deviation of controls after adjusting for age and body mass index (OPERA). For models involving multiple measures, we calculated the OPERA equivalent to the area under the receiver operating characteristic curve. Results For interval, screen-detected and younger-diagnosis cancer, the best fitting models (OPERAs [95% confidence intervals]) were: Cumulus (1.81 [1.41 to 2.31]) and Cirrus (1.7 [1.38 to 2.14]); Cirrus (1.49 [1.32 to 1.67]) and Cirrocumulus (1.16 [1.03 to 1.31]); and Cirrus (1.70 [1.48 to 1.94]) and Cirrocumulus (1.46 [1.27 to 1.68]), respectively. Their OPERA equivalents were: 2.35, 1.58, and 2.28, respectively. Conclusions Our mammogram-based measures improved risk prediction beyond and, except for interval cancers, negated the influence of conventional mammographic density. Combined, these new mammogram-based risk measures are at least as accurate as the current polygenetic risk scores (OPERA ~ 1.6) in predicting, on a population basis, women who will be diagnosed with breast cancer.

Received March 1, 2020 Revised May 10, 2020 Accepted May 25, 2020 In recent decades, due to the rapid consumption of natural resources and the need for environmental protection, sustainability in supply chain management has emerged as an increasingly important issue. Therefore, in this study, supplier selection has been performed in order to achieve sustainability, taking into account all aspects: economic, social and environmental criteria. For this purpose, combined FUCOM Rough SAW approach has been used. The evaluation of criteria grouped at two levels has been carried out by decision makers according to the needs of the company whose main activity is lime production. To obtain the criterion weight values, the FUCOM (FUll COnsistency Method) has been used.. In order to avoid uncertainty and imprecision in the supplier evaluation process, combination with the Rough SAW method, which is used for ranking and supplier selection, has been performed. In order to control the stability of the used model, a sensitivity analysis has been performed. The first phase involves changing the weights of the criteria, while the second phase involves a comparative analysis using other MCDM methods.

Purpose Ipilimumab, a monoclonal antibody inhibiting CLTA-4, is an established treatment in metastatic melanoma, either alone or in combination with nivolumab, and results in immune mediated adverse events, including endocrinopathy. Hypophysitis is one of the most common endocrine abnormalities. An early recognition of hypophysitis may prevent life threatening consequences of hypopituitarism; therefore, biomarkers to predict which patients will develop hypophysitis would have clinical utility. Recent studies suggested that a decline in TSH may serve as an early marker of IH. This study was aimed at assessing the utility of thyroid function tests in predicting development of hypophysitis. Methods A retrospective cohort study was performed for all patients ( n  = 308) treated with ipilimumab either as a monotherapy or in combination with nivolumab for advanced melanoma at the Royal Marsden Hospital from 2010 to 2016. Thyroid function tests, other pituitary function tests and Pituitary MRIs were used to identify those with hypophysitis. Results and conclusions Ipilimumab-induced hypophysitis (IH) was diagnosed in 25 patients (8.15%). A decline in TSH was observed in hypophysitis cohort during the first three cycles but it did not reach statistical significance ( P  = 0.053). A significant fall in FT4 ( P  < 0.001), TSH index ( P  < 0.001) and standardised TSH index ( P  < 0.001) prior to cycles 3 and 4 in hypophysitis cohort was observed. TSH is not useful in predicting development of IH. FT4, TSH index and standardised TSH index may be valuable but a high index of clinical suspicion remains paramount in early detection of hypophysitis.

Abstract Dumbbell schwannoma of the cervical spine is a known entity,1-5 and should be radically resected with the preservation or improvement of neurological function. However, to our knowledge, an operative video of a C1-C2 cervical dumbbell schwannoma with ventral extension and dorsal spinal cord compression has not been reported previously. This tumor resection video performed by the senior author (KIA) includes details of dural opening, and techniques for microsurgical resection and for postoperative closure to avoid cerebrospinal fluid (CSF) leak and pseudomeningocele formation. Fat grafting was performed through a small paraumbilical incision. The patient was prone in MAYFIELD 3-point pin fixation (Integra LifeSciences, Plainsboro Township, New Jersey). Intraoperative neurophysiological electrodes were placed for somatosensory evoked potential (SSEP) and motor evoked potential (MEP) monitoring. Stealth neuronavigation was used to aid in tumor localization. A small suboccipital craniectomy and C1 laminectomy were performed before opening the dura. Using a microsurgical technique, the dura was opened in the form of the letter “Y.” The right-sided dentate ligament was cut to aid in the mobilization of the tumor away from the spinal cord. After dividing the tumor at the dumbbell isthmus, the ventral tumor component was removed, with attention paid to the division of a perforator coming from the vertebral artery. Intraforaminal tumor debulking was performed with a cavitron ultrasonic surgical aspirator (CUSA) and resected. High cervical dumbbell schwannoma should be radically resected while preserving and improving preoperative neurological function. Avoidance of CSF leak and formation of pseudomeningocele should be planned at the beginning, utilizing fascia and fat graft to avoid this feared complication. The patient provided written consent and permission to publish her image.
