Published: September 2018

Abstract
The East Tianshan Mountain is one of the most important gold ore forming zones in northwestern China and central Asia. The Chinese GaoFen-1 (GF-1), the first Chinese high resolution satellite, is characterized by its 2-m resolution PAN data. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), the well-known earth observation satellite, is advanced by its finer spectral resolution owing 9 bands in the visible and near infrared (VNIR) to the short-wave infrared (SWIR) region. In this study, we fused the GF-1 PAN and the ASTER multispectral data using the well-known Gram-Schmidt Pan Sharpening (G-S) method to produce a new data with both high spatial and spectral resolution. Then different lithological units were mapped respectively using the fusion data, the ASTER data and the WorldView-3 data by support vector machine (SVM) method. In order to assess this fusion data, a comparison work was executed among the three mapping results. The comparison work indicated that lithological classification using the new fusion data is an efficient, robust and low cost method, and it could replace the WV-3 data in some large sale geological work.

Published: September 2018

Abstract
The AISI 1518 steel was pack-borided in the temperature range 1123–1273 K for a treatment ranging from 2 to 8 h. A compact single boride layer (Fe2B) was formed at the surface of the AISI 1518 steel using the mixture of powders composed of 20 % B4C, 10 % KBF4 and 70 % SiC. The following experimental techniques such as scanning electron microscopy coupled with EDS analysis and X-ray diffraction analysis were employed to characterize the pack-borided AISI 1518 steel. An alternative model, based on the integral mass balance equation, was used to estimate the boron diffusion coefficients in the Fe2B layers in the temperature range 1123–1273 K. Finally, the value of activation energy for boron diffusion in the AISI 1518 steel was estimated and compared with the literature data. Furthermore, the present model was validated by comparing the experimental value of Fe2B layer thickness, obtained at 1253 K for 2 h of treatment, with the predicted value.

Authors: Carvalho Pinto Eduardo , Petit Christophe 
Published: September 2018

Abstract
We provide a new heuristic polynomial time algorithm that computes short paths between arbitrary pairs of vertices in Lubotzky–Philipps–Sarnak’s Ramanujan graphs.
The paths returned by our algorithm are shorter by a factor approximately 16/7 compared to previous work, and they are close to optimal for vertices corresponding to diagonal matrices.
Our results also lead to an improved cryptanalysis of the Charles–Goren–Lauter hash function.

Authors: Sun Tao , Li Qingguo , Fan Nianbai 
Published: September 2018

AbstractIn this paper, we first introduce the notion of 𝓜𝓝-convergence in posets as an unified form ofO-convergence andO2-convergence. Then, by studying the fundamental properties of 𝓜𝓝-topology which is determined by 𝓜𝓝-convergence according to the standard topological approach, an equivalent characterization to the 𝓜𝓝-convergence being topological is established. Finally, the lim-inf𝓜-convergence in posets is further investigated, and a sufficient and necessary condition for lim-inf𝓜-convergence to be topological is obtained.

Authors: Ige S.A. , Bello O.B. , Alake O. 
Published: September 2018

Abstract
Low soil nitrogen is one of the principal abiotic stresses affecting maize productivity in Sub-saharan Africa. Field studies were conducted at the International Institute of Tropical Agriculture (IITA), Ibadan during the cropping seasons for three years, from 2010 to 2012, with ten open pollinated maize varieties (OPVs) derived from two breeding eras (1 and 2). The ten OPVs and their crosses were evaluated under high-N and low-N conditions. The aim was to identify superior populations that may be useful sources genes for inbred line extraction and hybrid development for grain yield. Under low-N condition, mid and high parent heterosis for grain yield were low indicating the suitability of the hybrids for cultivation only in environments with high productivity index. Hybrid DMR-LSR-W (Era 1) × TZSR-Y-I (Era 2) had greatest mid and high-parent heterosis for grain yield under high-N and across the other four test environments. Parent AMATZBR-WC2B with higher general combining ability effects and mean values for grain yield, and cross combinations DMR-LSR-W (Era 1) x BR9928DMRSR (Era 2) and BR9922DMRSR (Era 2) x TZBRELD-4C0W (Era 2) with higher specific combining ability for grain yield under low-N environment are promising candidates for the development of nitrogen use efficient varieties for cultivation in low-N environments.

Published: September 2018

Abstract
The Raman effect is at the basis of Raman scattering and microspectrometry: in the first part of the chapter, it is very shortly exposed together with differences with infrared (IR) spectroscopy, and advantages and drawbacks of the technique. The importance of the choice of the excitation wavelength, of the spectrometer (fixed, portable and handheld) and of the optics is underlined, while the information provided by the technique for inorganic and organic materials is considered. The surface-enhanced Raman spectroscopy (SERS) theory and principle applications are also taken into account. In the second part of the chapter, all the different applications of Raman and SERS to cultural heritage materials are contemplated: minerals, gemstones, rocks, patinas and corrosion products, glass, pottery, mortars, dyes, binders, resins, paper, parchment, inks and human remains. For each category of objects, the answers that Raman microspectrometry and SERS can give to the archaeometric and conservation-related questions, the in situ investigations, the search of specific spectral parameters and the use of chemometrics are shown, together with the most recent advances in the field.
Feeling spirits: sharing subjective paranormal experience through embodied talk and action
Authors: Ironside Rachael 
Published: September 2018

Abstract
This article examines how subjective paranormal experiences are shared and understood through embodied talk and action. Paranormal experiences often possess subjective qualities, regularly experienced as “senses” or “feelings”; however, the ability to share these experiences collectively provides the opportunity to validate such events. Drawing upon video data selected from over 100 hours of recorded footage during UK-based paranormal investigations, this study uses conversation analysis to examine how individuals communicate their experiences to others and through this evoke a way of understanding their experience as potentially paranormal. It is argued that embodied talk and action invite others to not only see the subjective paranormal experiences of others, but to understand and become co-experiencers in these events.
Distortion-Free Heat Treatment of Thin Rods in Magnetic Field
Authors: Pustovoit Viktor Nikolaevich , Dolgachev Yuri Vychislavovich 
Published: September 2018

Abstract
The problem of distortion during the quenching of thin rods (shafts, rollers, sewing needles, etc.) is serious, making vital the need for straightening (often by hand). The device for the heat treatment of thin rods was developed. The use of the device avoids distortion of the rods and improves their structural characteristics. A distinctive feature of the device is the use of a constant magnetic field (intensity up to 800 kA/m). The magnetic field performs an orienting function. When the part is immersed in the hardening liquid, the magnetic field of the solenoid orients the rod vertically. This ensures the magnetic fixation of the part. In addition, the magnetic field controls the heating temperature for quenching. The device was used for heat treatment of sewing needles made of U10A (UNS T72301) steel. The needles are held vertically in the upper part of the tube furnace by means of a magnetic field. When heated to a temperature of 740°C–750°C, the steel parts lose their ferromagnetic properties and fall vertically downwards. During the fall, they are further heated to a quenching temperature of 780°C. For this purpose, the height of the furnace (in this case 1,000 mm) is specially calculated. In the quench tank, the needles are in a strictly vertical position. In addition, the effect of the magnetic field on quenching leads to an enhancement of the martensitic transformation. The dispersity of individual crystals and laths of martensite increases. The volume fraction of lath martensite in alloys with a mixed morphology is increasing. The degree of self-tempering increases. The preferential arrangement of martensite crystals in the direction of the magnetic field lines is present. Thus, the device improves the structural characteristics of thin rods and excludes their distortion.

The study objective is to analyze the results of combined (direct and indirect) brain revascularization in adult patients with moyamoya disease. Materials and methods. From February 2015 to August 2016, 12 operations were performed on 12 hemispheres in 7 patients (2 men, 5 women) with moyamoya disease. Six patients had bilateral disease, 1 – unilateral. The age of patients ranged from 25 to 60 year old, the average – 41 year old. Multislice computed tomography (MSCT) perfusion imaging of the brain with a stress test was made in every patient, MSCT angiography of the extraand intracranial arteries was perfomed. Stages of the disease were determined according to the Suzuki–Takaku classification: stage III was revealed in 5 patients, stage IV – in 2. To evaluate the clinical course of the disease the Matsushima classification was used: type VI – in 2 cases, type III – in 2, type IV – in 1, type V – in 1. In 1 case, the pathological vascular network of 1 hemisphere was detected by accident. Extracranial-intracranial (EC–IC) bypass and encephaloduromyosynangiosis (EDMS) was used in 3 cases; a double-barreled EC–IC bypass and EDMS – in 3; a double-barreled EC–IC bypass and encephaloduroperiosteomyosynangiosis – in 1; EC–IC bypass and encephaloduroarteriomyosynangiosis (EDAMS) – in 3. In 1 case was perfomed EC–IC bypass and encephaloduroperiosteosynangiosis. Only indirect revascularization was performed in 1 case – EDAMS. We assessed the neurological status in the follow-up period (5–11 months); MSCT angiography and MSCT perfusion imaging of the brain were performed. Results. All patients in follow-up period demonstrated the increase of cerebrovascular reserve according to MSCT perfusion imaging of the brain with stress tests. Stroke, epilepsy, surgical complications were not detected in the postoperative period. In 1 case, the left-hand monoparesis regressed.Conclusion. The combined (direct and indirect) revascularization may be effective in adult patients with moyamoya disease. To obtain more objective conclusions it is necessary to analyze the long-term results of interventions.

Published: September 2018

The study objective is to analyze the results of using adenosine-induced cardioplegia during cerebral aneurysms clipping.Materials and methods. The study included 15 patients who underwent microsurgical aneurysm clipping during period from 2016 to 2017. Results. In all cases it was possible to completely isolate the aneurysm from the circulation. No complications associated with the administration of adenosine were observed. It was shown that adenosine-induced cardioplegia can be used when temporary clipping is impossible because of changing in the parent vessel. Also, the using of adenosine is useful for “simple” aneurysms, which leads to a softening of the sack without additional injuries.Conclusion. The combination of adenosine-induced cardioplegia and temporary clipping allows to provide better control over possible intraoperative bleeding and more comfortable positioning of the permanent clip on the aneurysm neck.

The study objective is analyze the modern ideas about the influence of time factor on the treatment outcome of patients with spinal cord injury. Results. Experimental studies clearly demonstrate the effectiveness of early decompression. According to the results of meta-analyses, in patients who underwent early decompression of the cervical segment of spinal canal, the outcomes of treatment may be better compared with the treatment outcomes of patients who underwent delayed intervention. The benefit of early decompression of the thoracic and lumbar spinal cord is not statistically significant. The difference in the rate of intraand postoperative complications and lethality between early and late decompression groups is also statistically insignificant.Conclusion. Early decompression of the spinal canal and spinal stabilization (≤24 h) should be performed in a specialized hospital as fully as possible and as early as the severity of the patient condition allows.

Authors: Nikitin A. S. , Grin A. A. 
Published: September 2018

The study objective is to analyze currently available publications on spinal deformity in patients with degenerative lumbar spinal stenosis.Materials and methods. We analyzed 90 manuscripts published between 1980 and 2017.Results. We describe the parameters used to assess spinal deformity and evaluate their role for predicting the course of degenerative spinal disease. We provide the results of latest studies assessing the impact of spinal deformity on the outcome of surgical treatment in patients with degenerative lumbar spinal stenosis. We identified the following risk factors for scoliosis progression: wedge-shaped intervertebral disc in the frontal projection, low middle sacral axis, lateral spondylolisthesis, small L vertebral body, vertebral rotation, Cobb angle >20°, and sagittal imbalance.Conclusion. We recommend decompressive interventions with facet joint preservation in patients with spinal deformity and degenerative lumbar spinal stenosis with no risk factors for scoliosis progression and radicular symptoms only (without pronounced low back pain). In patients with no risk factors for scoliosis progression, radicular symptoms, and low back pain, it is advisable to combine decompression with short fixation. For individuals at risk of scoliosis progression, we recommend supplementing decompression with long fixation exceeding scoliosis curve.

Published: September 2018

Biological invasions of exotic plants can seriously contribute to ecological imbalances within areas to which they have been introduced, affecting, in addition to native plants, cultivated species. Consequently, the objective of the current study was to evaluate effects of allelopathic extracts of three exotic species on
the physiological quality of crambe seeds. Aqueous extracts of Prosopis juliflora (Sw.) DC (algaroba) were formulated; Azadirachta indica A. Juss (Nim) and Cryptostegia madagascariensis Bojer ex Decne (viuvinha) at 20% (200 g of dried leaves per liter of distilled water) placed in B.O.D at 25 ° C for 24 h. Petri dishes, lined with germitest paper sheets, were moistened with aqueous extracts at 2,5 times de paper weight.
In the experimental trial, we used the completely randomized, with four treatments (three extracts + control treatment) and four replicates of 25 seeds. The first and second germination counts were evaluated in the fourth and tenth days respectively; germination rate index (GRI), allelopathic effect index (AEI), seedling length and dry mass. P. juliflora and C. madagascariensis reduced germination by 84 and 91%, respectively, in the first count. The GRI was affected by the three species, while the AEI showed greater allelopathy for C. madagascariensis, reaching -0.90. Seedlings lengths were reduced in the presence of P. juliflora and C. madagascariensis. For crambe seeds, all extracts negatively affected their physiological potential.

The efficient use of genetic resources- stored in germplasm collections can be maximized if morphoagronomic and molecular information on the accessions is made available. To achieve this, a collection that is well-structured, well-curated and easily accessible (the core collection) is required. Consequently, the objective of the current study was to characterize 80 landrace accessions from the maize core collection of the Federal University of Viçosa (UFV), and assay thenngenetic diversity of the various landraces, considering
grain type and ecogeographic origin. For this, AFLP analysis was performed using 12 primer combinations. Genetic diversity of the collection was quantified with the UPGMA method, using the Jaccard Index to quantify dissimilarity. The core collection was divided into four sub-populations by grain type, and into six sub-populations based on ecogeographic origin. Genetic diversity analysis was performed both within and between sub-populations. A high level of genetic variability was found among the landrace accessions of UFV Core Collection, principally among those accessions with dentate type grains.Classification by grain type and ecogeographic origin allowed genetically divergent groups to be distinguished.

Understanding secondary forest structure and functioning is essential for future planning of effective use and/or recompositioning of such areas. The secondary succession process is influenced by the characteristics of componente species, their interaction with other species and with abiotic components.
Thus, the objective of the current study was to evaluate the vegetation structure, dispersion syndromes and pollination of a secondary forest fragment with 5 years of regeneration in the Atlantic Forest landscape of Pernambuco, northern Brazil. A total of 30 permanent 10 x 10 m plots with 10 m separations were used
for canopy sampling (i.e., all woody individuals with stem diameter at 1.30 m (DBH) greater than 5 cm. Floristic composition analysis recorded 32 species from 21 families. Absolute density was 150 individuals with basal area of 4.787 m² ha-1, and the Shannon-Weaver index (H ‘) was 2.960. The family with the highest number of species was Melastomataceae, while those with greatest abundance were Malpighiaceae (26) and Cecropiaceae (14). Species with the highest Importance Values included Byrsonima sericea (49.28%), Cecropia pachystachya (38.49%) and Bowdichia virgilioides (37.19%). The predominant tree species dispersal syndrome was zoochory (72 species), and the predominant pollination syndrome was melitophilia. Arboreal individuals were mostly recorded in the initial diameter and height classes, indicating that the study area is in the initial stage of succession.
