Published: August 2018

Abstract
The paper presents a comprehensive study on the causes and effects of landslides occurring in the gmina Milówka (gmina is the administrative district in Poland, similar to a commune or municipality) from 1947 until today. The analysis includes the identification of probable causes of landslides and a discussion of possible remedial methods, including preventive ones. The following were considered: results of laboratory, geophysical and seismic tests; meteorological data; vegetative and transpirational properties of plants and agricultural crops; intensity of farming; forest clearance. Attention was also paid to the tree-ring eccentricity among spruces. Additionally, a numerical analysis of the current landslide stability was carried out in the Z_Soil program. Finally, it was found that determining the exact value of the stability coefficient is not possible due to the numerous assumptions necessary for the numerical analysis. However, it is possible to predict with high probability which of the slopes are threatened with landslides.

Цель работы. Целью работы является выявление основных характеристик и тенденций развития молочной отрасли России в условиях общей экономической стагнации. Метод или методология проведения работы. Исследование основывается на методах факторного анализа и междисциплинарного синтеза, которые предполагают точное разграничение социально-экономических сил, действующих на изучаемый объект. Основой данной работы являются исследования отечественных и зарубежных учёных по проблемам экономики и управления развитием молочной отрасли. Результаты. В условиях экономической стагнации в стране, когда спрос на продукцию молочной отрасли ограничен, государственное участие в развитии данной сферы хозяйства недостаточно. Так, из бюджетных средств на поддержку молочной отрасли более ¼ идёт на субсидирование части процентной ставки банков-кредиторов, что по своей сути – поддержка банковской отрасли, а не молочного производства РФ. Необходимо глубокое частно-государственное партнёрство: повышение стандартов качества сырья и готовой продукции; развитие племенных хозяйств по молочному животноводству; льготные социальные программы по восстановлению поголовья коз в хозяйствах населения; отмена НДС по молочной продукции; введение плавающей процентной ставки по ссудам молочной отрасли в размере не выше 75% от ключевой ставки ЦБ РФ. Нынешние формы государственного участия явно не перебарывают тенденции постепенной деградации молочной отрасли. Область применения результатов. Результаты проведенного исследования могут использоваться органами управления на уровне муниципальных районов и регионов при формировании системы управления инвестиционным развитием молочной отрасли на своей территории. Выводы. Выход из сложившейся ситуации может быть найден в развитии производственно-сбытовой кооперации, в ужесточении квот на ввоз сухого молока, запрете на использование пальмового масла в молочной отрасли, инвестиций в племенное дело, постоянном регулировании и контроле со стороны государства.

The aim of the current study
was to determine common physico-chemical parameters (salinity, temperature,
chlorophyll-a, dissolved oxygen, and
pH) of coastal water of two rocky shores from Buleiji and Paradise Point rocky
shores at Karachi monthly basis, from November 2007 to April 2009. The range of
air and surface water temperature of Buleji varies from 19 ºC to 30 ºC and 21ºC
to 29 ºC, respectively. Almost similar air temperature and seawater temperature
(19º to 29º C) were recorded at Paradise Point. Salinity ranged from 35 to 39 ‰
at Buleji while it ranged between 35 to 40 ‰ at Paradise Point. The lowest
concentrations of dissolved oxygen was recorded in November’07 and November’08
at both sites, at Buleiji which were 1.6 mg/L and 1.7 mg/L while at Paradise
Point it was 1.8 mg/L and 1.7 mg/L, respectively. The pH value ranged from 7.0
to 8.3 at Buleji and from 7.5 to 8.4 at Paradise Point. The concentrations of
chlorophyll-a were between 1.2 and 3.7
µg cm-2 at Buleji while it ranged from 0.9 to 3.3 µg cm-2 at Paradise Point.
Results showed that the obtained values of temperatures, salinity, pH and chlorophyll-a are favorable for the continued
survival of marine biota but the values of dissolved oxygen were found to be
below 4 mg/L which are not suitable for various species. Prolonged periods of
minimal dissolved oxygen directly upset larval stages of numerous marine
organisms. In Karachi coastal areas, seasonal accessibility of surface water is
very responsive to the monsoon climate and physiography of coastal belt. These
concerns were used to inform the common people and decision-makers about the
state of the coastal environments. To protect these dynamic significant
habitats, the government organizations and researchers should work with
appropriate consideration.

Imaging alone versus microelectrode recording–guided targeting of the STN in patients with Parkinson’s disease

Published: August 2018

OBJECTIVEThe clinical results of deep brain stimulation (DBS) of the subthalamic nucleus (STN) are highly dependent on accurate targeting and target implantation. Several targeting tactics are in current use, including image-only and/or electrophysiologically guided approaches using microelectrode recordings (MERs). The purpose of the present study was to make an appraisal of imaging only–based versus imaging with the addition of intraoperative MER-guided STN electrode targeting.METHODSThe authors evaluated 100 consecutive patients undergoing STN DBS. The position of the STN target was estimated from preoperative MR images (direct target) or in relation to the position of the anterior and posterior commissures (indirect target). MERs were obtained for each trajectory. The authors tracked which targets were adjusted intraoperatively as a consequence of MER data. The final placement of 182 total STN electrodes was validated by intraoperative macrostimulation through the implanted DBS electrodes. The authors compared the image-based direct, indirect, MER-guided target adjustments and the final coordinates of the electrodes as seen on postoperative MRI.RESULTSIn approximately 80% of the trajectories, there was a good correspondence between the imaging-based and the MER-guided localization of the STN target. In approximately 20% of image-based targeting trajectories, however, the electrophysiological data revealed that the trajectory was suboptimal, missing the important anatomical structures to a significant extent. The greatest mismatch was in the superior-inferior axis, but this had little impact because it could be corrected without changing trajectories. Of more concern were mismatches of 2 mm or more in the mediolateral (x) or anteroposterior (y) planes, discrepancies that necessitated a new targeting trajectory to correct for the mis-targeting. The incidence of mis-targetting requiring a second MER trajectory on the first and second sides was similar (18% and 22%).CONCLUSIONSAccording to the present analysis, approximately 80% of electrodes were appropriately targeted using imaging alone. In the other 20%, imaging alone led to suboptimal targeting that could be corrected by a trajectory course correction guided by the acquired MER data. The authors’ results suggest that preoperative imaging is insufficient to obtain optimal results in all patients undergoing STN DBS.

OBJECTIVEPrevious work from the authors has shown that hand ergonomics plays an important role in surgical psychomotor performance during virtual reality brain tumor resections. In the current study they propose a hypothetical model that integrates the human and task factors at play during simulated brain tumor resections to better understand the hand ergonomics needed for optimal safety and efficiency. They hypothesize that 1) experts (neurosurgeons), compared to novices (residents and medical students), spend a greater proportion of their time in direct contact with critical tumor areas; 2) hand ergonomic conditions (most favorable to unfavorable) prompt participants to adapt in order to optimize tumor resection; and 3) hand ergonomic adaptation is acquired with increasing expertise.METHODSIn an earlier study, experts (neurosurgeons) and novices (residents and medical students) were instructed to resect simulated brain tumors on the NeuroVR (formerly NeuroTouch) virtual reality neurosurgical simulation platform. For the present study, the simulated tumors were divided into four quadrants (Q1 to Q4) to assess hand ergonomics at various levels of difficulty. The spatial distribution of time expended, force applied, and tumor volume removed was analyzed for each participant group (total of 22 participants).RESULTSNeurosurgeons spent a significantly greater percentage of their time in direct contact with critical tumor areas. Under the favorable hand ergonomic conditions of Q1 and Q3, neurosurgeons and senior residents spent significantly more time in Q1 than in Q3. Although forces applied in these quadrants were similar, neurosurgeons, having spent more time in Q1, removed significantly more tumor in Q1 than in Q3. In a comparison of the most favorable (Q2) to unfavorable (Q4) hand ergonomic conditions, neurosurgeons adapted the forces applied in each quadrant to resect similar tumor volumes. Differences between Q2 and Q4 were emphasized in measures of force applied per second, tumor volume removed per second, and tumor volume removed per unit of force applied. In contrast, the hand ergonomics of medical students did not vary across quadrants, indicating the existence of an “adaptive capacity” in neurosurgeons.CONCLUSIONSThe study results confirm the experts’ (neurosurgeons) greater capacity to adapt their hand ergonomics during simulated neurosurgical tasks. The proposed hypothetical model integrates the study findings with various human and task factors that highlight the importance of learning in the acquisition of hand ergonomic adaptation.

OBJECTThis study proposes a variation of the transorbital endoscopic approach (TOEA) that uses the lateral orbit as the primary surgical corridor, in a minimally invasive fashion, for the posterior fossa (PF) access. The versatility of this technique was quantitatively analyzed in comparison with the anterior transpetrosal approach (ATPA), which is commonly used for managing lesions in the PF.METHODSAnatomical dissections were carried out in 5 latex-injected human cadaveric heads (10 sides). During dissection, the PF was first accessed by TOEAs through the anterior petrosectomy, both with and without lateral orbital rim osteotomies (herein referred as the lateral transorbital approach [LTOA] and the lateral orbital wall approach [LOWA], respectively). ATPAs were performed following the orbital approaches. The stereotactic measurements of the area of exposure, surgical freedom, and angles of attack to 5 anatomical targets were obtained for statistical comparison by the neuronavigator.RESULTSThe LTOA provided the smallest area of exposure (1.51 ± 0.5 cm2, p = 0.07), while areas of exposure were similar between LOWA and ATPA (1.99 ± 0.7 cm2 and 2.01 ± 1.0 cm2, respectively; p = 0.99). ATPA had the largest surgical freedom, whereas that of LTOA was the most restricted. Similarly, for all targets, the vertical and horizontal angles of attack achieved with ATPA were significantly broader than those achieved with LTOA. However, in LOWA, the removal of the lateral orbital rim allowed a broader range of movement in the horizontal plane, thus granting a similar horizontal angle for 3 of the 5 targets in comparison with ATPA.CONCLUSIONSThe TOEAs using the lateral orbital corridor for PF access are feasible techniques that may provide a comparable surgical exposure to the ATPA. Furthermore, the removal of the orbital rim showed an additional benefit in an enhancement of the surgical maneuverability in the PF.

Published: August 2018

OBJECTIVERete middle cerebral artery (MCA) is extremely rare and has not been frequently discussed. Rete MCA is a weblike anomaly of the MCA that does not coalesce and forms a prominent, large single branch from the plexiform vessels in the fetal stage. The purpose of this study was to further elucidate the clinical and radiological characteristics of patients with rete MCA.METHODSA total of 2262 cerebral digital subtraction angiography procedures were performed on 1937 patients at the authors’ institution from February 2013 to May 2017. Data analysis included age, sex, clinical symptoms, underlying diseases, coexisting cerebral arterial anomalies, and operative methods and findings.RESULTSRete MCAs were found in 13 patients, and the incidence of this anomaly was 0.67% (13 of 1937) in this study. Of the 13 patients, 3 had hemorrhagic strokes, 6 had ischemic strokes, and 4 had no symptoms. Eight patients underwent conservative treatment, and 5 patients underwent surgical treatment. Rete MCA is considered a congenital disease of the cerebral vasculature with the possibility of an acquired abnormality, such as an aneurysm, caused by hemodynamic stress. Although an epidemiological survey of rete MCA was not conducted, it is assumed that rete MCA has a high prevalence in Asia. Ischemic and hemorrhagic stroke events are fairly common in rete MCA.CONCLUSIONSClinicians should understand the radiological and clinical features of patients with rete MCA to avoid misdiagnosis and unnecessary treatment. This anomaly should be differentiated from other vascular diseases and patients presenting incidentally should be carefully monitored because of their vulnerability to both hemorrhagic and ischemic strokes.

The explicit formulation of the velocity and acceleration kinematics for the Movemaster RV-M1 robot is presented. The formulae are obtained from the tool position transformation matrix. The derived formulation allowed creating a Matlab graphical user interface for simulation of kinematic tasks and calculation of velocity and acceleration, for both tool and robot joints. A vertical linear weld type kinematic task was simulated and later carried out in the actual robot using programming commands and hardware provided by the manufacturer. An angular velocity DAQ was built to measure the velocities of the joints in the fi xed coordinate system, and used in the experimental stage. From the results, a satisfactory validation of the mathematical formulae was made. The derived formulation for this robot was available had not been presented before.

Published: August 2018

Abstract
We use dense redshift surveys to explore the properties of galaxy clusters selected from the redMaPPer catalog. Our new survey, Hectospec Cluster Survey of red-sequence-selected clusters (HeCS-red), includes 10,589 new or remeasured redshifts from MMT/Hectospec observations of 27 redMaPPer clusters at redshifts z = 0.08–0.25 with large estimated richnesses (richness estimate λ > 64). Our spectra confirm that each candidate cluster corresponds to a large overdensity in redshift space. The redMaPPer photometric redshifts have a slight bias toward higher redshifts. We measure the relation between velocity dispersion σ

p
and λ. The relation shows intrinsic scatter of 24% (and a range of 2x) in velocity dispersion at fixed richness. We extend our analysis to HeCS-red-ext, a sample that includes several clusters selected by X-ray flux or Sunyaev–Zeldovich signal. The heterogeneous sample of 121 clusters in HeCS-red-ext shows similar intrinsic scatter in the σ

p
–λ relation as the HeCS-red sample, but the range of σ

p
at fixed richness increases to 3x. We evaluate the membership probability estimates P
mem for individual galaxies provided by redMaPPer. The spectroscopic membership fraction is larger than P
mem for 0.05 ≤ P
mem ≤ 0.7; conversely, the spectroscopic membership fraction is smaller than P
mem at P
mem ≥ 0.8. We compare spectroscopic richness estimates with redMaPPer richness estimates and find good agreement on average, but a range of a factor of two in spectroscopic richness at fixed redMaPPer richness. Overall, within the high-richness and low-redshift cut of our sample, spectroscopically estimated parameters such as velocity dispersion correlate well with photometric richness estimates, although the relations contain substantial scatter.
