Published: August 2020

Aims The aim of this study was to use diffusion tensor imaging (DTI) to investigate changes in diffusion metrics in patients with cervical spondylotic myelopathy (CSM) up to five years after decompressive surgery. We correlated these changes with clinical outcomes as scored by the Modified Japanese Orthopedic Association (mJOA) method, Neck Disability Index (NDI), and Visual Analogue Scale (VAS). Methods We used multi-shot, high-resolution, diffusion tensor imaging (ms-DTI) in patients with cervical spondylotic myelopathy (CSM) to investigate the change in diffusion metrics and clinical outcomes up to five years after anterior cervical interbody discectomy and fusion (ACDF). High signal intensity was identified on T2-weighted imaging, along with DTI metrics such as fractional anisotropy (FA). MJOA, NDI, and VAS scores were also collected and compared at each follow-up point. Spearman correlations identified correspondence between FA and clinical outcome scores. Results Significant differences in mJOA scores and FA values were found between preoperative and postoperative timepoints up to two years after surgery. FA at the level of maximum cord compression (MCL) preoperatively was significantly correlated with the preoperative mJOA score. FA postoperatively was also significantly correlated with the postoperative mJOA score. There was no statistical relationship between NDI and mJOA or VAS. Conclusion ms-DTI can detect microstructural changes in affected cord segments and reflect functional improvement. Both FA values and mJOA scores showed maximum recovery two years after surgery. The DTI metrics are significantly associated with pre- and postoperative mJOA scores. DTI metrics are a more sensitive, timely, and quantifiable surrogate for evaluating patients with CSM and a potential quantifiable biomarker for spinal cord dysfunction.

YAZLIK MESCİTLERE KAVRAMSAL VE TİPOLOJİK BİR YAKLAŞIM
Authors: ŞANCI Fuat 
Published: August 2020

Bu makalede dini mimari içerisinde ele alınan yazlık mescitler incelenmiş olup, bunların son cemaat mahallerinden tamamen farklı olduğu ve yazlık mekân, yazlık namazgah, namazgah gibi isimlerden de ayrı bir kavramla ifade edilmesi gerektiği düşünülmektedir.
Konumuz olan yazlık mescitler, namazgâhlardan minberlerinin bulunmayışı ve bir cami avlusunda bulunuyor olmaları ile ayrılırlar. Bunlar verdikleri hizmet açısından da farklılık gösterirler. Namazgâhlar şehir dışında yaşayanlara, yolculara hizmet vermek için veya büyük insan kitlelerini bir araya toplamak üzere inşa edilirken, yazlık mescitler şehirde yaşayan insanların bir arada ibadet için toplanmalarına yönelik bir uygulamadır. İşlevsel olarak; namazgahlar cuma mescitlerini, yazlık mescitler ise mescitleri karşılamaktadır. Bu tür yapıların sıcak iklimin hakim olduğu yerleşim yerlerinde yaygın kullanım alanı bulduğu görülmüştür.
A CONCEPTUAL AND TYPOLOGOCAL APPROACH TO SUMMER MASJIDS
Abstract

In this article, ‘summer masjid’ is discussed as part of religious architecture to develop the argument that it is essentially different from the last congregation area (son cemaat yeri), thus deserves a separate name rather than being referred to as a summer venue, summer prayer place, or prayer place (namazgâh).
Summer masjid is distinguished from prayer places called namazgâh in that it does not feature a minbar and is located inside the mosque yard. These also differ in terms of the services they provide. Prayer places called namazgâh serve the residents of suburbs or the countryside, as well as wayfarers, and are made for bigger crowds; whereas the summer masjid is a meeting point for city dwellers who prefer worshipping together as a congregation. In terms of their functions, namazgâh corresponds to the Friday masjid and summer masjid to masjid proper.

A fim de aprimorar o ensino e a aprendizagem dos alunos que participaram do cursinho popular “EduCursinho”, este estudo avaliou a eficiência dos métodos de ensino vivenciados pelos alunos na escola e no projeto, assim como analisou a principal maneira com que eles absorveram os conteúdos. A metodologia aplicada envolveu o uso de questionários, cujas perguntas foram elaboradas de acordo com a teoria de estilo de aprendizagem do método visual, auditivo e cinestésico (VAC). Os resultados mostraram que 43% dos participantes possuíam a aprendizagem beneficiada por meio de recursos visuais e, em parcela igual a 29%, os participantes restantes eram auditivos e cinestésicos. Além disso, as respostas relacionadas à aprendizagem de Química demonstraram que a principal dificuldade em entender os conceitos da disciplina estava relacionada à falta de conexão da matéria com a realidade, sendo necessário maior contextualização do tema com vivências comuns do dia a dia. Portanto, concluiu-se que os resultados foram satisfatórios e serão de grande valia para as próximas edições do projeto, bem como para futuras análises que complementem ainda mais a aprendizagem e o ensino de Química nas escolas e nos cursinhos populares do Brasil.
Maternal Exposure to the Cannabinoid Agonist WIN 55,12,2 during Lactation Induces Lasting Behavioral and Synaptic Alterations in the Rat Adult Offspring of Both Sexes

Published: August 2020

AbstractConsumption of cannabis during pregnancy and the lactation period is a rising public health concern (Scheyer et al., 2019). Exposure to synthetic or plant-derived cannabinoids via lactation disrupts the development of GABAergic neurons in the prefrontal cortex (PFC) and alters early-life behaviors (Scheyer et al., 2020b). Recently, additional data revealed that Δ9-tetrahydrocannabinol (THC) perinatal exposure via lactation causes lasting behavioral and neuronal consequences (Scheyer et al., 2020a). Here, the long-term effects in adult offspring of maternal exposure to the synthetic cannabinoid agonist WIN 55,12,2 are reported. The data demonstrate that rats exposed during lactation to WIN display social and motivational deficits at adulthood. These behavioral changes were paralleled by a specific loss of endocannabinoid-mediated long-term depression (eCB-LTD) in the PFC and nucleus accumbens (NAc), while other forms of synaptic plasticity remained intact. Thus, similarly to THC, perinatal WIN exposure via lactation induces behavioral and synaptic abnormalities lasting into adulthood.
Sinoglobalizáció - Retorika csupán, vagy a jövőt meghatározó valóság?
Authors: Erdősi Ferenc 
Published: August 2020

A globalizáció és az amerikanizáció után a 21. század elején kibontakozóban van a Kína által képviselt sajátos „sinoglobalizáció”. A cikk célja, hogy felhívja az olvasó figyelmét az egész emberiség szempontjából több mint releváns jelenségre. A globalizáció sokféle attribútumai közül e rövid írás a gazdasági vonatkozásokra koncentrál. Arra, hogy az új szereplő globalizációhoz való viszonya hogyan változott gazdasági ereje növekedésének, a szabályozók liberalizálódásának, külpolitikája/külgazdasága nyitottá válásának következtében. A globalizációba megkésetten bekapcsolódó, autokrata ideológia által vezérelt országóriás a klasszikus amerikainál gyorsabb tempóval (rengeteg nem kívánatos kísérőjelenség árán) alkalmazkodó félből a globalizáció tudatos alakítójává lépett elő. Önálló globalizációs stratégiája megalkotásához az alapot különleges erősségű anyagi és szellemi koncentrációja biztosítja.
Kína külkereskedelmi forgalomban, majd 2019-ig ipari teljesítményben, infokommunikációs csúcstechnológiai kutatási eredményekben felzárkózott az USA-hoz. Ezen túlmenően a gazdasági globalizáció olyan kulcsjellemzői is tetten érhetők a kapcsolatrendszerében, mint a nemzetközi összefonódás, egyesülés és uniformizálódás, vagy a kétirányú tőkemozgás. Kína ambíciói „a világ színpadán” több vonatkozásban is meglepőek. A sinoglobalizációban különleges szerepet kaptak a nagyhatalom által létesített gigantikus közlekedési, távközlési és energetikai infrastrukturális hálózatok. A tengeri és transzkontinentális közlekedésfejlesztések, a Délkelet-Ázsiától Nyugat-Európa partjaiig tartó stratégiai fontosságú kikötőláncon történt (változó erősségű) berendezkedés a világhatalmi státusz felé egyengeti az utat, ahogyan a saját műszaki szabványainak érvényesítése is az általa kiszolgált idegen területeken.
A 2020. évi pandémia távlati következményeiről megjelent forgatókönyvek nem sok jót ígérnek Kínának. Meggyőződésünk, hogy Kína a világkatasztrófa által legkevésbé sújtott országok közé tartozik a 2020-as években. Erre biztosítékot látunk gazdasági szerkezetének radikális modernizálásában, exportfüggőségének mérséklődésében, a lakossági fogyasztás korábbi gyors növekedésének folytatódásában és az általa patronált fejlődő országok sokaságából beáramló hatalmas nyereségben.

Objective: to evaluate short-term and long-term outcomes of lymph node dissection in patients with stage III–IV ovarian cancer.Materials and methods. This retrospective study included patients with stage III–IV ovarian cancer who have undergone either complete or optimal cytoreduction. Patients in the experimental group additionally had lymph node dissection, whereas patients in the control group had surgery without lymph node dissection. We evaluated 3‑year relapse-free survival (primary outcome measure), 3‑year overall survival, incidence of intraoperative and postoperative complications, and frequency of lymph node lesions.Results. The study included 272 patients: 43 women in the experimental group and 229 women in the control group. Intraoperative complications were significantly more common in patients who had lymph node dissection compared to those who had cytoreductive surgery alone (37.2 % vs 16.6 % respectively; р = 0.0001). The incidence of postoperative complications did not vary significantly between the groups (27.9 % in the experimental group vs 16.2 % in the control group; р = 0.128). Thirty-three patients (76.7 %) were found to have metastasis in the lymph nodes excised. The three-year overall survival rate was 82.6 % among patients who had lymph node dissection and 75.7 % among patients who had no lymph node dissection (р = 0.306). The three-year relapse-free survival rate was 26.2 % in the experimental group and 38.4 % in the control group (р = 0.858).Conclusions. Systemic lymph node dissection does not improve long-term outcomes and increases the incidence of intraoperative complications in patients with stage III–IV ovarian cancer undergoing complete or optimal cytoreduction.

Permeability Variation and Its Impact on Oil Recovery from Unconsolidated Sand Heavy-Oil Reservoirs during Steamflooding Process
Authors: Zhong Liguo , Han Xiaodong , Yuan Xiaonan , Liu Yigang , Zou Jian , Wang Qiuxia 
Published: August 2020

Summary
In the steam-injection processing of unconsolidated heavy-oil reservoirs, the pore space may change because of the overburden pressure increase and wormhole generation. Meanwhile, injected high-temperature steam can result in mineral dissolution and alteration and consequent diameter change of sand particles and pore space. To obtain a better and more thorough understanding of permeability variation characteristics during the steamflooding process, a series of experiments with sand-packed tubes was designed and conducted. On the basis of quantified experimental data, a numerical model was built by taking various permeability variation mechanisms into consideration. Reservoir simulations were consequently carried out to study the permeability distribution variation on the field scale and its impact on oil recovery. The results showed that with increasing overburden pressure, the permeability and porosity of the sand tube were both decreased. Permeability decrease ranged from 35 to 54%, and porosity decrease was approximately 5%. The partial permeability was increased by more than four times when a wormhole was generated at the outlet. The permeability and porosity of sand-packed tubes were increased because of mineral dissolution in the steamflooding process. Particle migration and mineral dissolution resulted in permeability variation and formation of a high-permeability region in the reservoir, which enhanced the heterogeneity of the reservoir. The high-permeability region mainly formed at the upper layer of the reservoir in the vertical direction and on the line between steam injection and oil production wells in the horizontal direction. Permeability variation exacerbated the steam channeling, which resulted in more remaining oil and a lower oil recovery rate of the reservoir. When permeability variation was considered in a numerical simulation, the cumulative oil production for 4 years was decreased by approximately 7000 m3, and the oil recovery rate was decreased by 4.3%.
Determining Attributes of Finite Fracture Networks in Low-Permeability Carbonate Reservoirs
Authors: Ozkaya Sait I. 
Published: August 2020

SummaryCarbonate reservoirs usually consist of multiple units each with different degrees of layer-bound fracture density, height, length, and angular scatter. Some units may have finite fracture networks (FFNs), and some others may contain only isolated fractures. FFNs are islands of interconnected fractures within a sea of isolated fractures. The fracture volume can be estimated from the initial surge in production if a wellbore intersects only a single FFN. Combining with fracture density and aperture measurements from borehole images, FFN volume, drainage area, and other relevant attributes can be calculated. If, however, a slanted well intersects an unknown number of FFNs each in a different unit, it is not possible to estimate each FFN fracture volume from initial fracture production. Because the connectivity threshold for initiation of FFNs is not known or cannot be calculated, it is not possible to determine how many FFNs the borehole intersects. One way is to set an arbitrary threshold of fracture connectivity, λc.Based on this initial value, a fracture-flow model can be generated and adjusted until the inferred rate time and cumulative time curves converge to observed values. The adjustment is accomplished by changing the number of FFNs using different connectivity threshold λc and estimating their size by modifying unknown or uncertain parameters such as fracture aperture. The final model yields the mostly likely number and size of all FFNs and provides an approximate forecast for future production performance.The ability to match production performance without taking pressure into consideration shows that rate decrease in fractured reservoirs with FFNs is not only related to pressure drawdown but also, perhaps more importantly, to depletion of FFNs starting from the smallest size or the one with highest drainage efficiency.One drawback of the method is that different numbers of FFNs may have similar inferred production performance and cumulative production. This is an inevitable drawback inherent in most models that must rely on multiple uncertain or unknown parameters. The only way to decrease the range of possible solutions is to decrease the uncertainties in the underlying input parameters. In any case, alternative results may be presented as a range of possible solutions.
