Boehmite Nanofiber-Reinforced Resorcinol-Formaldehyde Macroporous Monoliths for Heat/Flame Protection
Authors: Hayase Gen
Published: July 2018

By distributing boehmite nanofibers (BNFs) to a resorcinol-formaldehyde (RF) skeletal phase formed by phase separation in an aqueous sol, composite macroporous monoliths have been produced. The nanofiber reinforced monoliths have a skeleton in which BNF is arranged in parallel within the RF structure, and showed high Young's modulus against uniaxial compression for their bulk density. These materials can be expected to be applied to heat/flame protection materials using heat insulating properties and high flame resistance.

Para Argentina se citan tres especies de Ceiba (Malvaceae, Bombacoideae): C. chodatii, C. speciosa y C. pubiflora, diferenciadas por pocos caracteres. Las dos primeras especies se distinguen claramente en etapa de floración, siendo complicada su identificación en otros estadios. El objetivo de esta investigación es revisar comparativamente a C. chodatii y C. speciosa en la búsqueda de mayores caracteres que aporten a su delimitación. Se estudiaron ejemplares nativos de C. chodatii en la Selva pedemontana y en Chaco serrano, también de C. speciosa cultivados en Salta y provenientes de herbarios. Se estudiaron todos los caracteres vegetativos y reproductivos, con lupa binocular y MEB. Se realizó un ensayo de germinación y desarrollo de plántulas. Los resultados muestran que las hojas desde plántula hasta adulto se diferencian en nerviación y aserrado del margen. Los caracteres diferenciales en flor son: el tamaño de los lóbulos en la columna de estaminodios y la pubescencia, el tamaño de las anteras y collar, la concrescencia total o parcial de los filamentos estaminales, la forma, tamaño y pubescencia del estigma y el tipo de pubescencia basal del estilo. Los frutos se diferencian por el espesor de las valvas y las semillas por pubescencia.

Cultural Changes in Neural Structure and Function
Authors: Varnum Michael E. W. , Hampton Ryan Scott
Published: July 2018

Human cultures are not static. An emerging body of research has documented cultural changes in a wide variety of behaviors, psychological tendencies, and cultural products. Increasingly, this field has also begun to test hypothesis regarding the causes of these changes and to create forecasts for future patterns of change. Yet to date, the question of how our brains may change as a function of systematic changes in our environments has received relatively little attention and scant empirical testing. In the present chapter we begin by reviewing the literature on cultural change, including Varnum and Grossmann’s program of research using a behavioral ecology framework to understand patterns of cultural change. Next we offer some initial predictions for changes in neural structure and function that may occur in the coming decades. Finally, we offer some ideas about how empirical research testing these predictions might be conducted and discuss challenges and opportunities for extending the study of cultural change to neuroscience.
The Attentional Template is Shifted and Asymmetrically Sharpened by Distractor Context
Authors: Yu Xinger , Geng Joy
Published: July 2018

Theories of attention hypothesize the existence of an “attentional template” that contains target features in working or long-term memory. It is often assumed that the template contents are veridical, but recent studies have found that this is not true when the distractor set is linearly separable from the target (e.g., all distractors are “yellower” than an orange colored target). In such cases, the target representation in memory shifts away from distractor features (Navalpakkam & Itti, 2007) and develop a sharper boundary with distractors (Geng, DiQuattro & Helm, 2017). These changes in the target template are presumed to increase the target-to-distractor psychological distinctiveness and lead to better attentional selection, but it remains unclear what characteristics of the distractor context produce shifting vs. sharpening. Here, we test the hypothesis that the template representation shifts whenever the distractor set (i.e., all of the distractors) is linearly separable from the target, but that asymmetrical sharpening only occurs when linearly separable distractors are highly target-similar. Our results were consistent, suggesting that template shifting and asymmetrical sharpening are two mechanisms that increase the representational distinctiveness of targets from expected distractors and improve visual search performance.

Russian Abstract: Цель статьи выявление и интерпретация географических особенностей либерально-демократических электоральных предпочтений населения в Республике Армения. Для этого анализировалось структура политического пространства РА в 1998-2008гг. и существование в этом пространстве политических сил разных идеологических ориентаций. Для выявления географических особенностей либерально-демократических электоральных предпочтений населения, анализировалось результаты участия либерально-демократических политических сил (партий и кандидатов) в президентских и парламентских выборах последнего десятилетия. В итоге с помощью сопоставления и пространство-временного анализа итогов парламентских и президентских выборов, автор пришел к выводу, что в РА при голосовании за либерально-демократических политических сил существует раскол 'север-юг' при котором население северных регионов (марзов) голосует преимущественно за либерально-демократических политических сил, а население южных регионов голосует преимущественно за национально-консервативных политических сил.English Abstract: The purpose of this article is to reveal and analyze the general geographical features of liberal-democratic electoral preferences of the population in the Republic of Armenia, therefore, the structure of political landscape of RA for 1998-2008 period and the existence of political forces with different ideological orientation in this landscape has been analyzed. In order to reveal the geographical features of liberal-democratic electoral preferences of the population, the voting for liberal-democratic political forces at presidential and parliamentary elections of the last decade have been analyzed. As a result of the comparative and spatiotemporal analysis, the papers concludes that in RA in the voting for liberal-democratic political forces there is a north-south 'cleavage', namely the population of northern regions votes mainly for liberal-democratic political forces, while the population of the southern regions mainly votes for national-conservative ones.

Recurrent laryngeal nerve identified using methylene blue smear and compared with the conventional visualization techniques exercising different known anatomical landmarks. The duration and ease of identification of the nerve was noted and graded.Results: Total of 39 recurrent laryngeal nerves were identified from 28 females and two males. The duration and the ease of dissection of the nerve was inconstant. Earliest time for recognition of the nerve was one and half minutes while the slowest time was 12 minutes. Conclusion: No matter what techniques are used, visual identification and verification of the recurrent laryngeal nerve is of paramount importance. No techniques demonstrated added advantage to one another.
Popularity and Monarchy:The Hampton Court Conferenceand the Early Jacobean Church
Authors: Morgan John
Published: July 2018

Building on recent reconsiderations of James I's Church policies, this article ties James's performance at the Hampton Court conference to his Scottish experiences, his texts on kingship and what he perceived in the Church of England upon arrival in his new realm. The linking thread is not theology but rather his fervent anti-popularity, bred in his reaction to the Scottish Reformation, rejection of Buchanan's limited monarchy theories and struggles to exert and expand his kingship in Scotland. In England, he found natural allies in a late Elizabethan tradition of anti-popularity. The puritan petitioning campaign for Church reform convinced him that nonconformity equated with popularity and that he had to crush it immediately (as intimated in Basilikon Doron), if he was to be a “free” monarch. At the conference, James made clear that he would have a strong episcopal church as a bulwark protecting his kingship against any popular challenge. The subsequent rigorous conformity campaign and purge of unyielding ministers indicate that far from seeking an irenic compromise, James sought to extirpate any challenge from below to his authority as Supreme Governor.

OBJECTIVE

The role of radiosurgery (RS) in treating superficial cavernous malformations (CMs) is insufficiently studied in part because of the disappointing results of early experimental attempts as compared to the mostly safe and effective microsurgery. Nonetheless, because of lesion- or treatment-specific factors, a therapeutic alternative may be required. In this study, the authors aimed to assess the safety of RS in treating superficial CMs and to analyze its long-term effect on hemorrhage rates and epilepsy control.

METHODS

The authors conducted a retrospective analysis of 96 patients with 109 CMs located in the cerebral or cerebellar hemispheres and treated with RS between 1995 and 2014. A median of 15 Gy (range 10–25 Gy) was given to the 50% prescription isodose level, lesion volume was 604 mm3 (4–8300 mm3), and the prescription isodose volume was 638.5 mm3 (4–9500 mm3). Outcomes were compared to those of 206 deep-seated lesions reported on in another study. Ninety-five patients had available follow-up, which was a median of 7 years (1–21 years). Median patient age was 42 years (0.5–77) at presentation and 45 (3–80) at treatment. Seventy-one CMs presented with symptomatic hemorrhage, and 52 caused seizures.

RESULTS

In the nonhemorrhagic group (37 lesions), one bleed occurred during the follow-up period, for an annual bleed rate of 0.4% per lesion. The lifetime annual bleed rate of CMs having a single hemorrhage prior to treatment was 2.5%. The rebleed rate in the single-bleed group decreased from 1.8% within the first 2 years after RS to 0.7% thereafter. The pretreatment rebleed rate for lesions having multiple bleeds prior to RS was 14.15%, which fell to 3.85% for the first 2 years after RS and declined to 1.3% thereafter. Multivariate analysis showed younger age, deep lesion location, and multiple pretreatment hemorrhages as significant predictors of posttreatment hemorrhage.

Pretreatment hemorrhages led to permanent deficits in 41.4% of the cases with a single bleed and in 46.1% of cases with multiple bleeds. Only mild (modified Rankin Scale score 1) and a low rate of permanent neurological deficits were caused either by posttreatment hemorrhages (4.3%) or by radiation (2%).

The rate of improvement in epilepsy was 84.9% after RS in patients with at least one seizure prior to treatment, not depending on the presence of hemorrhage or the time interval between presentation and treatment. Favorable outcome occurred in 81% of patients whose seizures were not controlled with antiepileptic medication prior to RS.

CONCLUSIONS

Radiosurgery for superficial CMs is safe and appears to be effective, offering a real treatment alternative to surgery for selected patients. Given their relatively benign natural history, superficial CMs require further study to verify the long-term benefit of RS over the lesions’ natural history.

Published: July 2018

OBJECTIVE

The S2-alar-iliac (S2AI) screw is an increasingly popular method for spinopelvic fixation. The technique of freehand S2AI screw placement has been recently described. The purpose of this study was to demonstrate, through a CT imaging study of patients with spinal deformity, that screw trajectories based on the posterior superior iliac spine (PSIS) and sacral laminar slope result in reliable freehand S2AI trajectories that traverse safely above the sciatic notch.

METHODS

Fifty consecutive patients (age ≥ 18 years) who underwent primary spinal deformity surgery were included in the study. Simulated S2AI screw trajectories were analyzed with 3D visualization software. The cephalocaudal coordinate for the starting point was 15 mm cephalad to the PSIS. The mediolateral coordinate for the starting point was in line with the lateral border of the dorsal foramina. The cephalocaudal screw trajectory was perpendicular to the sacral laminar slope. Screw trajectories, lengths, and distance above the sciatic notch were measured.

RESULTS

The mean sagittal screw angle (cephalocaudal angulation) was 44.0° ± 8.4° and the mean transverse angle (mediolateral angulation) was 37.3° ± 4.3°. The mean starting point was 5.9 ± 5.8 mm distal to the caudal border of the S1 foramen. The mean screw length was 99.9 ± 18.6 mm. Screw trajectories were on average 8.5 ± 4.3 mm above the sciatic notch. A total of 97 of 100 screws were placed above the sciatic notch. In patients with transitional lumbosacral anatomy, the starting point on the lumbarized/sacralized side was 3.4 mm higher than on the contralateral unaffected side.

CONCLUSIONS

The PSIS and sacral laminar slope are two important anatomical landmarks for freehand S2AI screw placement.

Вокальные миниатюры Клода Дебюсси 1890-х годов: новый вектор художественных исканий
Authors: Qing Li
Published: July 2018

Камерно-вокальная музыка Дебюсси неизменно привлекает внимание музыковедов.  В этом контексте в числе наиболее актуальных оказываются вопросы периодизации вокальных сочинений. Начало 90-х годов XIX века открывает новый период творчества Клода Дебюсси. Заканчивается «пора ученичества», изменяется жанровая панорама его музыки (на первый план выходят инструментальные сочинения, устанавливается интерес к оперному жанру), но именно вокальные сочинения этих лет позволяют глубже осознать новые векторы художественных исканий композитора. Этот ракурс рассмотрения вокального наследия К. Дебюсси и определил цель данной статьи: выявить изменения творческих принципов композитора в 90-е годы XIX века и уточнить критерии периодизации его камерно-вокальных сочинений.Ключевые слова: Клод Дебюсси, вокальная миниатюра, французская музыка 1890-х годов, Стефан Малларме
