Nova objetividade e nova subjetividade
Authors: Braga Paula 
Published: September 2017

A obra Tropicália apresentada por Hélio Oiticica na exposição Nova Objetividade Brasileira, bem como o texto escrito pelo artista para o catálogo da mostra anunciam a ênfase no coletivo e na potência da arte como fomentadora de subjetivações que não separam os âmbitos da ética, política e estética. Assim, é possível alinhar as estruturas ambientais de Oiticica a estruturas conceituais de pensadores como Jacques Rancière, Gilles Deleuze e Toni Negri, identificando os labirintos do artista carioca como estruturas emancipadoras, nomádicas e construtoras da multidão.

Published: September 2017

Aggressive open lumbar discectomy is the most commonly performed surgical procedure for patients with persistent low back and leg pain. In this retrospective study, 1,380 patients were evaluated for long-term results of aggressive discectomy for the single level lumbar disk herniation. Demographic data, surgical data, complications and reherniation rate were collected and clinical outcomes were assessed using visual analogue score (VAS), Oswestry disability index (ODI) and modified Mcnab criteria. The mean follow-up period was 28.8 months. According to the modified Mcnab criteria, the long-term results were excellent in 640 cases, good in 445 cases, fair in 255 cases, and poor in 40 cases. The mean VAS scores for back and radicular pains and ODI at the end of 2 years were 1.1 ± 1.0, 1.5 ± 0.5 and 6.6 ± 3.1% respectively. The complications were foot drop (n=7), dural tear (n=14), superficial wound infection (n=17), discitis (n=37) and reherniation (n=64). The dural tear and superficial wound infections resolved after treatment but 28 discitis patients were treated by conservatively and the remaining 9 underwent surgery. Among reherniation patients, 58 underwent revision discectomy and 4 underwent transforaminal lumbar interbody fusion and stabilization. Aggressive discectomy is an effective treatment of lumbar disk herniation and maintains a lower incidence of reherniation but leads to a collapse of disc height and in long run gives rise to intervertebral instability and accelerates spondylosis.
Free Multivariate w*-Semicrossed Products: Reflexivity and the Bicommutant Property
Authors: Bickerton Robert T. , Kakariadis Evgenios T. A. 
Published: September 2017

AbstractWe study w*-semicrossed products over actions of the free semigroup and the free abelian semigroup on (possibly non-selfadjoint) w*-closed algebras. We show that they are reflexive when the dynamics are implemented by uniformly bounded families of invertible row operators. Combining with results of Helmer, we derive that w*-semicrossed products of factors (on a separableHilbert space) are reflexive. Furthermore, we show that w*-semicrossed products of automorphic actions on maximal abelian self adjoint algebras are reflexive. In all cases we prove that the w*-semicrossed products have the bicommutant property if and only if the ambient algebra of the dynamics does also.
Homological Dimensions of Local (Co)homology Over Commutative DG-rings
Authors: Shaul Liran 
Published: September 2017

AbstractLet A be a commutative noetherian ring, let a ⊆ A be an ideal, and let I be an injective A-module. A basic result in the structure theory of injective modules states that the A-module Γa(I) consisting of ɑ-torsion elements is also an injective A-module. Recently, de Jong proved a dual result: If F is a flat A-module, then the ɑ-adic completion of F is also a flat A-module. In this paper we generalize these facts to commutative noetherian DG-rings: let A be a commutative non-positive DG-ring such that H0(A) is a noetherian ring and for each i < 0, the H0(A)-module Hi(A) is finitely generated. Given an ideal ⊆ H0(A), we show that the local cohomology functor R associated with does not increase injective dimension. Dually, the derived -adic completion functor LΛ does not increase flat dimension.
Infinite Powers and Cohen Reals

Published: September 2017

AbstractWe give a consistent example of a zero-dimensional separable metrizable space Z such that every homeomorphism of Zω acts like a permutation of the coordinates almost everywhere. Furthermore, this permutation varies continuously. This shows that a result of Dow and Pearl is sharp, and gives some insight into an open problem of Terada. Our example Z is simply the set of ω1 Cohen reals, viewed as a subspace of 2ω.
A Spectral Identity on Jacobi Polynomials and its Analytic Implications
Authors: Awonusika Richard , Taheri Ali 
Published: September 2017

AbstractThe Jacobi coefficientsare linked to the Maclaurin spectral expansion of the Schwartz kernel of functions of the Laplacian on a compact rank one symmetric space. It is proved that these coefficients can be computed by transforming the even derivatives of the Jacobi polynomialsinto a spectral sum associated with the Jacobi operator. The first few coefficients are explicitly computed, and a direct trace interpretation of the Maclaurin coefficients is presented.

Conservação das espécies vegetais em paleoambientes dunares na APA Dunas e Veredas do Baixo-Médio São Francisco, Bahia, Brasil
Authors: Pacheco Clecia Simone Gonçalves Rosa , Oliveira Niédja Maria Galvão Araújo 
Published: September 2017

Apesar do avanço do conhecimento científico que se tem atualmente, com dados sobre a flora e sua respectiva distribuição, esse ainda não é completo e não permite que se prescinda da experiência de campo, intraduzível em termos de determinação da composição florística e características das plantas e do meio. Mediante tal pressuposto, este artigo objetiva demonstrar o levantamento das espécies vegetais realizado na Área de Proteção Ambiental (APA) Dunas e Veredas do Baixo-Médio São Francisco, e sua relevância para a manutenção do equilíbrio ecológico do paleo-ecossistema dunar. É possível afirmar que a vegetação é o espelho do clima e, sendo o espelho do clima, percebe-se que algumas espécies encontradas representam a fisionomia dos climas atuais, mas podendo indicar resquícios de paleoclimas. Desta maneira, a vegetação é vista coma à chave da manutenção do equilíbrio dinâmico do ecossistema e sua preservação é defendida por esta razão. Trata-se de uma pesquisa qualitativa e de cunho exploratório, onde fundamentou-se a priori em teóricos que abordam sobre tal temática e, em seguida utilizou-se o Método de Caminhamento introduzido por Filgueiras et al., (1994) sendo que, o uso deste, tem se mostrado eficiente para elaborar o levantamento qualitativo de grande parte da variabilidade florística em diferentes fitofisionomias. A pesquisa in loco possibilitou a identificação de várias espécies exóticas, endêmicas e, nativas da região semiárida, além de outras típicas de áreas mais úmidas (Floresta Amazônica, Floresta Atlântica e Áreas de Transições). Portanto, os resultados indicam a urgência da criação de planos estratégicos de conservação da diversidade florística da área dunar, tendo em vista que os vegetais ali presentes, são responsáveis pela estabilização das areias eólicas dos campos, e sem estas, consequentemente ter-se-á o agravamentos dos processos de degradação ambiental já evidente na área.

A presente pesquisa tem como objetivo discutir sobre o papel das mulheres na preservação do ambiente demonstrando o vínculo em que ela desenvolve com a natureza. Neste sentido, o trabalho confirma algumas informações importantes na relação entre mulher e natureza, direitos que garantam a inclusão do gênero em várias questões sociais, culturais e ambientais. Podemos apontar, entretanto, que a relação de proximidade com o tema ambiental, a mulher está, na maioria das vezes, longe do processo de tomada de decisão em relação às políticas ambientais. Sendo assim, este artigo permite uma melhor compreensão das relações que as mulheres estabelecem com a natureza, no material, social e cultural, o que mostra a importância do seu papel na preservação do ambiente.
How long should the fully hillside-closed forest protection be implemented on the Loess Plateau, Shaanxi, China?
Authors: Hou Lin , Hou Sijia 
Published: September 2017

Background
Restoration of degraded forest ecosystem is crucial for regional sustainable development. To protect the country’s fragile and fragmented environment, the Chinese government initiated an ecological engineering project, the Natural Forest Protection Program, in seventeen provinces in China beginning in 1998. Fully hillside-closed forest protection (vegetation restoration naturally without any artificial disturbance) was one of vital measures of the Natural Forest Protection Program applied nation wide. Whether plant diversity, biomass and age structure of dominant tree species and soil nutrients in protected stands may become better with increase of protected period are still open problems.

Methods
We investigated community diversity, biomass of dominant tree species, age structures, and analyzed soil chemical properties of a Pinus tabulaeformis population at protected sites representing different protected ages at Huanglongshan Forest Bureau on the Loess Plateau, Shaanxi, China.

Results
Plant species richness of Pinus tabulaeformis community was significantly affected (p < 0.05) by forest protection and the effect attenuated with protection age. Shannon evenness index of plant species generally increased with protection age. Stands protected for 45 years had the highest tree biomass and considerable natural regeneration capacity. Contents of organic carbon, available phosphorus and available potassium in top soil increased in protected stands less than 45 years, however decreased significantly thereafter. Long-term forest protection also decreased the content of mineral nitrogen in top soil.

Discussion
We found that the richness of shrubs and herbs was significantly affected by forest protection, and evenness indices of tree, shrub and herb increased inconsistently with protected ages. Forest protection created more complex age structures and tree densities with increasing age of protection. Content of soil mineral nitrogen at 0–20 cm soil depth showed a decreasing trend in stands of up to 30 years. Soil available phosphorus and potassium contents were higher in stands with greater proportions of big and medium trees. Long-term protection (>45 years) of Pinus tabulaeformis stands in southeast Loess Plateau, China, may be associated with decreasing plant species richness, proportion of medium to large trees, dominant biomass of Pinus tabulaeformis and soil nutrients.

The El Niño Modoki in 2010 led to historic droughts in Brazil. In order to understand its impact on carbon cycle variability, we derive the 2011–2010 annual carbon flux change (δF↑) globally and specifically to Brazil using the NASA Carbon Monitoring System Flux (CMS‐Flux) framework. Satellite observations of CO2, CO, and solar‐induced fluorescence (SIF) are ingested into a 4D‐variational assimilation system driven by carbon cycle models to infer spatially resolved carbon fluxes including net ecosystem production, biomass burning, and gross primary productivity (GPP). The global 2011–2010 net carbon flux change was estimated to be δF↑=−1.60 PgC, while the Brazilian carbon flux change was −0.24 ± 0.11 PgC. This estimate is broadly within the uncertainty of previous aircraft‐based estimates restricted to the Amazon basin. The 2011–2010 biomass burning change in Brazil was −0.24 ± 0.036 PgC, which implies a near‐zero 2011–2010 change of the net ecosystem production (NEP): The near‐zero NEP change is the result of quantitatively comparable increases GPP (0.31 ± 0.20 PgC) and respiration in 2011. Comparisons between Brazilian and global component carbon flux changes reveal complex interactions between the processes controlling annual land‐atmosphere CO2 exchanges. These results show the potential of multiple satellite observations to help quantify and spatially resolve the response of productivity and respiration fluxes to climate variability.
Statistical Characteristics of Convective Clouds over the Western Ghats Derived from Weather Radar Observations

Published: September 2017

AbstractX‐band radar observations at Mandhardev (18.04°N, 73.85°E) are used to investigate statistics of convective clouds over the Western Ghats during monsoon season (June–September 2014). Convective storms (cells) are identified using an objective‐tracking method to examine their spatiotemporal variability, thus quantifying the time‐continuous aspects of convective cloud population over the region for the first time. An increased frequency of storm location and initiation along the windward mountains compared to coastal and lee side highlights orographic response to southwesterly flow, with superimposed diurnal cycle. An eastward progression of convective activity from upstream the barrier through windward slopes of mountains over to the lee side is observed. Storm area, height, and duration follow lognormal distributions; wherein, small‐sized storms contribute more to total population and unimodal distribution of 35 dBZ top heights (peaking at 5.5 km) depicts the dominance of shallow convection. Storms exhibit a pronounced diurnal cycle with a peak in afternoon hours, while the convective area maximum is delayed by several hours to that of precipitation flux. Cell lifetime and propagation show that cells move with slow speeds and have mean duration of 46 min. They align east‐west nearly parallel to mountain ridges, and their direction of movement is steered mostly by large‐scale winds at lower levels. Based on top heights, convective cells are further classified into cumulus, congestus, and deep clouds. In general, congestus (deep) cells are most abundant in the windward (leeward) side. A lead‐lag relationship between congestus and deep cells indicates midtroposphere moistening by congestus cells prior to deep convection.
Resolving the Model‐Observation Discrepancy in the Mesospheric and Stratospheric HOx Chemistry

Published: September 2017

AbstractWe examine the middle atmospheric odd‐hydrogen (HOx) chemistry by comparing the Aura Microwave Limb Sounder (MLS) OH and HO2 measurements with a photochemical model simulation. The model underestimates mesospheric OH and HO2 concentrations if the standard chemical kinetic rates are used, whether the model H2O and O3 are constrained with observations or not. To resolve the discrepancies, we adjust the kinetic rate coefficients of three key reactions (O + OH → O2 + H, OH + HO2 → H2O + O2, and H + O2 + M → HO2 + M) and the O2 photo absorption cross section at Lyman α (121.57 nm) using the Bayesian optimal estimation. A much better model‐observation agreement can be achieved if the kinetic rate coefficients for H + O2 + M → HO2 + M is increased by 134–310%, and the O2 photo absorption cross section at Lyman α is reduced by 33–54%, while the kinetic rate coefficients for O + OH → O2 + H and OH + HO2 → H2O + O2 remain consistent with the current laboratory values. The kinetic rate coefficient for H + O2 + M → HO2 + M requires a very large adjustment beyond the uncertainty limits recommended in the NASA Data Evaluation, suggesting the need for future laboratory measurements. An alternative explanation is that the radiative association reaction, H + O2 → HO2 + hν, plays a significant role, which has never been measured. Our results demonstrate that high‐quality satellite observations can be used to constrain photochemical parameters and help improve our understanding of atmospheric chemistry.
