Authors: Ravindra Vijay M. , Kralik Stephen F. , Griauzde Julius , Gadgil Nisha , LoPresti Melissa A. , Lam Sandi
Published: March 2020

OBJECTIVE

Moyamoya disease is a progressive occlusive arteriopathy for which surgical revascularization is indicated. In this retrospective study, the authors investigated the use of preoperative CT perfusion with the aim of establishing pathological data references.

METHODS

The authors reviewed the medical records of children with moyamoya disease treated surgically at one institution between 2016 and 2019. Preoperative CT perfusion studies were used to quantify mean transit time (MTT), cerebral blood volume (CBV), cerebral blood flow (CBF), and time to peak (TTP) for the anterior, middle, and posterior cerebral artery vascular territories for each patient. CT perfusion parameter ratios (diseased/healthy hemispheres) and absolute differences were compared between diseased and normal vascular territories (defined by catheter angiography studies). Sensitivity, specificity, and positive (PPV) and negative (NPV) predictive values for CT perfusion parameters for severe angiographic moyamoya were calculated.

RESULTS

Nine children (89% female) had preoperative CT perfusion data; 5 of them had evidence of unilateral hemispheric disease and 4 had bilateral disease. The mean age at revascularization was 77 months (range 40–144 months). The etiology of disease was neurofibromatosis type 1 (3 patients), Down syndrome (2), primary moyamoya disease (2), cerebral proliferative angiopathy (1), and sickle cell disease (1). Five patients had undergone unilateral revascularization. Among these patients, pathological vascular territories demonstrated increased MTT in 66% of samples, increased TTP in 66%, decreased CBF in 47%, and increased CBV in 87%. Severe moyamoya (Suzuki stage ≥ 4) had diseased/healthy ratios ≥ 1 for MTT in 78% of cases, for TTP in 89%, for CBF in 67%, and for CBV in 89%. The MTT and TTP region of interest ratio ≥ 1 demonstrated 89% sensitivity, 67% specificity, 80% PPV, and 80% NPV for the prediction of severe angiographic moyamoya disease.

CONCLUSIONS

Pathological hemispheres in these children with moyamoya disease demonstrated increased MTT, TTP, and CBV and decreased CBF. The authors’ results suggest that preoperative CT perfusion may, with high sensitivity, be useful in deciphering perfusion mismatch in brain tissue in children with moyamoya disease. More severe angiographic disease displays a more distinct correlation, allowing surgeons to recognize when to intervene in these patients.

Published: March 2020

Global neurosurgery is the practice of neurosurgery with the primary purpose of delivering timely, safe, and affordable neurosurgical care to all who need it. This field is led by neurosurgeons, and global neurosurgery sessions are now part of every major international neurosurgical meeting. The World Federation of Neurosurgical Societies (WFNS) is working to coordinate activities and align all related activities for greater impact. This report updates the contributions made by the WFNS-WHO Liaison Committee at the most recent World Health Assembly (WHA) in 2019. The WHA is a decision-making body of the World Health Organization (WHO), attended by its 194 Member States. The WFNS has maintained official relations as a nongovernmental organization with the WHO for over 30 years, and this year 15 neurosurgical delegates attended events during the WHA. Participation by neurosurgeons continues to grow as many WHA events focused on global surgery have intrinsically involved neurosurgical leadership and participation. This year, resolution WHA72.31, entitled “Emergency and trauma care, Emergency care systems for universal health coverage: ensuring timely care for the acutely ill and injured,” was passed. This resolution provides further opportunities for neurosurgical advocacy as the landscape of global surgery gains recognition and momentum.
Growing Coconut Palms in the Pacific Islands: Colliding Knowledge and Values
Authors: Bennett Judith A.
Published: March 2020

Coconuts provided commodities for the West in the form of coconut oil and copra. Once colonial governments established control of the tropical Pacific Islands, they needed revenue so urged European settlers to establish coconut plantations. For some decades most copra came from Indigenous growers. Administrations constantly urged the people to thin old groves and plant new ones like plantations, in grid patterns, regularly spaced and weeded. Local growers were instructed to collect all fallen coconuts for copra from their groves. For half a century, the administrations' requirements met with Indigenous passive resistance. This paper examines the underlying reasons for this, elucidating Indigenous ecological and social values, based on experiential knowledge, knowledge that clashed with Western scientific values.

The efficiency of air cooling at the inlet of the main low-speed engine turbocharger of a transport vessel during operation in tropical climatic conditions on the Shanghai-Singapore-Shanghai route was analyzed. A feature of the tropical climate is the high relative humidity, respectively, moisture content at its simultaneously high temperatures. The cooling of the air at the inlet of a low-speed engine with an ejector chiller by transforming the waste heat of exhaust gases into cold was studied. The ejector chiller is used as the most simple and reliable in operation. However, the efficiency of the transformation of heat into cold by ejector chillers is low - low thermal coefficients.A design solution of the system for cooling air at the inlet of the ship's main engine using the heat of the exhaust gases by an ejector chiller is proposed and analyzed. The effect of using the heat of the exhaust gases to cool the air at the engine inlet is analyzed taking into account the variable climatic conditions during the voyage of the vessel. It is shown that because of the insufficiently high efficiency of transforming the waste heat of the exhaust gases by an ejector chiller (low thermal coefficients), the obtained cooling capacity is not sufficient for cooling the air at the inlet of the turbocompressor during operation of a marine engine in tropical climatic conditions. Therefore, the possibility of use in the ejector chiller of additional heat of charge air, which is removed by cooling water, is also considered. It is shown that the use of the heat of exhaust gases and charge air for cooling the air at the engine inlet in an ejector chiller makes it possible to double decrease the air temperature at the inlet of the main engine by 20-30 °C when the vessel operates in tropical climatic conditions on a voyage lines Shanghai-Singapore-Shanghai. This, in turn, provides an almost twice fuel consumption reduction in compared with its reduction in the case when the ejector chiller uses only the heat of the exhaust gases.
ANALYSIS OF TWO-STEP APPROACH FOR COMPRESSING TEXTURE IMAGES WITH DESIRED QUALITY

considered. Quality is mainly characterized by the peak signal-to-noise ratio (PSNR) but visual quality metrics are briefly studied as well. Potentially, a two-step approach can be used to carry out a compression with providing the desired quality in a quite simple way and with a reduced compression time. However, the two-step approach can run into problems for PSNR metric under conditions that a required PSNR is quite small (about 30 dB). These problems mainly deal with the accuracy of providing a desired quality at the second step. The paper analyzes the reasons why this happens. For this purpose, a set of nine test images of different complexity is analyzed first. Then, the use of the two-step approach is studied for a wide set of complex structure texture test images. The corresponding test experiments are carried out for several values of the desired PSNR. The obtained results show that the two-step approach has limitations in the cases when complex texture images have to be compressed with providing relatively low values of the desired PSNR. The main reason is that the rate-distortion dependence is nonlinear while linear approximation is applied at the second step. To get around the aforementioned shortcomings, a simple but efficient solution is proposed based on the performed analysis. It is shown that, due to the proposed modification, the application range of the two-step method of lossy compression has become considerably wider and it covers PSNR values that are commonly required in practice. The experiments are performed for a typical image encoder AGU based on discrete cosine transform (DCT) but it can be expected that the proposed approach is applicable for other DCT-based image compression techniques.

Air pollution occurs when harmful or excessive quantities of substances including gases, particles, and biological molecules are introduced into Earth's atmosphere. It may cause diseases, allergies and even death to humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment. Both human activity and natural processes can generate air pollution. Indoor air pollution and poor urban air quality are listed as two of the world’s worst toxic pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places report. Outdoor air pollution alone causes 2. 1 to 4. 21 million premature deaths annually. According to the 2014 World Health Organization report, air pollution in 2012 caused the deaths of around 7 million people worldwide, an estimate roughly echoed by the International Energy Agency. Though government is taking several measures to control air pollution it is rising rapidly due to urbanization, excessive usage of automobiles, factories, construction works. , etc. , As we cannot deny the fact that development without transport, infrastructure and factories is not possible. We have to search for alternate means of air pollution reduction. However air purification / filtration requires lot of energy to drive induced air fans it is better to use solar energy rather than going for conventional thermal energy. As a part of our project dissertation we are planning to fabricate a solar air purification system for reduction of air pollution.

Authors: Kovács György , Benotsmane Rabab , Dudás László
Published: March 2020

Recent tendencies – such as the life-cycles of products are shorter while consumers require more complex and more unique final products – poses many challenges to the production. The industrial sector is going through a paradigm shift. The traditional centrally controlled production processes will be replaced by decentralized control, which is built on the self-regulating ability of intelligent machines, products and workpieces that communicate with each other continuously. This new paradigm known as Industry 4.0. This conception is the introduction of digital network-linked intelligent systems, in which machines and products will communicate to one another in order to establish smart factories in which self-regulating production will be established. In this article, at first the essence, main goals and basic elements of Industry 4.0 conception is described. After it the autonomous systems are introduced which are based on multi agent systems. These systems include the collaborating robots via artificial intelligence which is an essential element of Industry 4.0.
MONITORING OF OPERATIONAL LOGISTIC PROCESSES IN GENERAL CARGO WAREHOUSES USING PREDICTIVE ANALYSIS
Authors: Neubert Andreas
Published: March 2020

Due to the different characteristics of the piece goods (e.g. size and weight), they are transported in general cargo warehouses by manually-operated industrial trucks such as forklifts and pallet trucks. Since manual activities are susceptible to possible human error, errors occur in logistical processes in general cargo warehouses. This leads to incorrect loading, stacking and damage to storage equipment and general cargo. It would be possible to reduce costs arising from errors in logistical processes if these errors could be remedied in advance. This paper presents a monitoring procedure for logistical processes in manually-operated general cargo warehouses. This is where predictive analysis is applied. Seven steps are introduced with a view to integrating predictive analysis into the IT infrastructure of general cargo warehouses. These steps are described in detail. The CRISP4BigData model, the SVM data mining algorithm, the data mining tool R, the programming language C++ for the scoring in general cargo warehouses represent the results of this paper. After having created the system and installed it in general cargo warehouses, initial results obtained with this method over a certain time span will be compared with results obtained without this method through manual recording over the same period.

Disordered motility is one of the most important pathogenic characteristics of unctional dyspepsia (FD), although the underlying mechanisms remain unclear. Since the sympathetic system is important to the regulation of gastrointestinal motility, the present study aimed to investigate the role of norepinephrine (NE) and adrenoceptors in disordered gastric motility in a rat model with FD. The effect of exogenous NE on gastric motility in control and FD rats was measured through an organ bath study. The expression and distribution of β-adrenoceptors were examined by real-time PCR, Western blotting and immunofluorescence. The results showed that endogenous gastric NE was elevated in FD rats, and hyperreactivity of gastric smooth muscle to NE and delayed gastric emptying were observed in the rat model of FD. The mRNA levels of β1-adrenoceptor and norepinephrine transporter (NET) and the protein levels of β2-adrenoceptor and NET were increased significantly in the gastric corpus of FD rats. All three subtypes of β-adrenoceptors were abundantly distributed in the gastric corpus of rats. In conclusion, the enhanced NE and β-adrenoceptors and NETs may be contributed to the disordered gastric motility in FD rats.

Este artículo derivado de la investigación para acceder al título de Magister del Centro de Estudios Superiores del Noroeste S.C- Universidad Cesun de México-Ciudad de Tijuana- Baja California, y titulado “Los nuevos políticos:  el papel de los personeros por fuera y dentro de la escuela” intenta poner de manifiesto la importancia de la formación democrática y participativa en la escuela como una de las bases del desarrollo personal y político de los sujetos que participan en el gobierno escolar, y que a futuro podrán ser los gobernantes de una nación. En primer lugar, se establecen los mecanismos legales de la participación ciudadana desde los estamentos escolares y cómo se fomenta ciudadanía a partir de la figura de gobierno escolar; seguidamente se intenta definir el papel que debe jugar la educación en la formación política desde la escuela. Por último, las posturas que tienen los filósofos de la escuela clásica de Frankfurt frente al papel que debe asumir cada ciudadano como participe de una sociedad, que continua el legado de las revoluciones en busca de la libertad, la igualdad y la justicia.  Esta reflexión permite una autocrítica al sistema educativo colombiano y al papel del maestro, quien debe ser el ejemplo de sujeto crítico, reflexivo y político, un sujeto participe de la construcción de una ciudadanía democrática enfocado en el desarrollo humano a partir de los procesos educativos.

Estimation of Evapotranspiration of a Jujube/Cotton Intercropping System in an Arid Area Based on the Dual Crop Coefficient Method
Authors: Ai Pengrui , Ma Yingjie
Published: March 2020

An accurate estimation of crop evapotranspiration (ETc) in intercropping is critical for a theoretical basis for formulating an intercropping irrigation system of fruit trees and improving the soil moisture condition of orchards in arid regions of Southern Xinjiang. Herein, observational data such as soil moisture and plant physiological indicators were measured in jujube/cotton intercropping in the Aksu region from 2015 to 2017. The evapotranspiration of single-crop jujube and cotton was estimated using the modified dual crop coefficient method. Then, based on the proportion of intercropping crops, the soil water stress coefficient was introduced to estimate the evapotranspiration of the jujube/cotton intercropping. The results show that the model has good applicability to simulate single-crop jujube and cotton, and jujube/cotton intercropping. However, compared with single cropping, the accuracy of simulated daily evapotranspiration was decreased. In addition, adjusting the cotton irrigation amount caused the simulation accuracy to further decrease. From the perspective of interspecies complementarity and competition, cotton dominated the intercropping system and had better tolerance to external environmental changes than jujube trees. Intercropping had negative effects on jujube trees in general, and very obvious positive effects on cotton. Based on the 3-year crop yield, 5-year-old jujube trees are recommended for intercropping. During this time, the yield of cotton under the effect of interspecific complementation increased by 26.47%, and the yield of intercropping jujube was similar to that of single crop. As the jujube tree age increases, the effect of increasing cotton production gradually diminishes. The jujube trees also had a significant reduction in yield due to interspecific competition. Our research supports the dual crop coefficient method as appropriate to estimate crop ETc in intercropping and may be further used to improve irrigation scheduling for jujube/cotton intercropping.
