Medical science says that ischemia is a common complication in Diabetes, especially in the lower limb but this is a case presenting ischemic changes in upper limb which is unique and also in such type of acute ischemia amputation is the only choice of treatment to save the life of patient from septicaemia. Such a rare and interesting case was taken at Sri Sri Ayurveda Hospital and handled by proper Ayurvedic line of treatment by which circulation is re-established which saved both limb and life of patient. A patient by name Sundaramma, 62yr Female, visited Sri Sri Ayurveda Hospital on 29/2/2016 with a diagnosis of Right upper limb Ischemia with Diabetes Mellitus and Active TB. The main symptoms were severe pain and burning sensation in Right hand and forearm, discolouration of fingers with ulcers, Bluish black discolouration over right thumb, necrosis, pus dischargeand stiffness, associated with difficulty in movement of right arm, shoulder joint, elbow joint, palm and fingers. Diagnosed as Right Upper Limb Ischemia with Diabetes Mellitus and active TB. Therapeutic interventions like Right upper limb Doppler and CT angiogram were done. Such a complicated case was taken at Sri Sri Ayurveda Hospital, and carefully handled by Ayurvedic methods of management, which was ended up by preventing amputation of the limb and also achieving the re-establishment of arterial circulation.

Authors: Reis Arthur Ferreira
Published: July 2017

Os estudos sobre independência revelam a importância da imprensa no processo de formação do Estado nacional. Através de jornais e panfletos diversos autores se pronunciaram sobre um período de intenso debate político e exaltação dos ânimos. Entretanto, a imprensa foi constantemente perseguida e reprimida pelas autoridades imperiais, seja no Primeiro Reinado, seja na Regência. Temos como objetivo tratar das consequências que a repressão à imprensa teve para os debates ocorridos no período, expondo algumas vertentes de compreensão da opinião pública no Brasil. A seguir, procuramos relacionar tais vertentes com os autores excluídos dos debates graças à repressão a imprensa. Por fim, apontamos as formas legais utilizadas pelo governo na repressão de jornalistas considerados radicais.
Almas ousadas, naturezas impetuosas: crime e degenerescência na literatura de Bram Stoker (1847-1912)
Authors: Silva Evander Ruthieri da
Published: July 2017

Na segunda metade do século XIX, letrados, médicos e juristas fizeram amplo uso da cultura escrita e literária para problematizar as dimensões sociais e biológicas do crime, em narrativas sintomáticas de suas preocupações a respeito dos problemas urbanos. Este estudo detém-se sobre dois textos literários do anglo-irlandês Bram Stoker (1847-1912), The Primrose Path (1875) e The Secret of the Growing Gold (1892), ambos publicados na imprensa periódica, os quais evidenciam as interpretações do literato a respeito da figura social do criminoso a partir de apropriações de teses degeneracionistas e de preocupações de âmbito racial.
Escrita biográfica e escrita da história no pensamento de Wilhelm Dilthey
Authors: Avelar Alexandre De Sá
Published: July 2017

A obra de Wilhelm Dilthey é associada, frequentemente, ao seu projeto de fundação das ciências humanas, tarefa à qual dedicou toda a sua vida intelectual. O caráter inconclusivo e fragmentário de sua obra tornou difícil a compreensão de outros aspectos relevantes do seu pensamento. Este artigo tem como objetivo principal se debruçar sobre um destes aspectos, a saber, as relações que o filósofo estabelece entre biografia e escrita da história a partir, sobretudo, de dois caminhos: a conexão com a concepção de Dilthey sobre as ciências humanas e o exame de alguns de seus textos propriamente biográficos.
Homenagem a Oliveira Lima na Revista de História (1912-1928), uma publicação periódica portuguesa, dirigida por Fidelino de Figueiredo
Authors: Moreira Nuno Bessa
Published: July 2017

No seu volume final, que condensa a atividade de dois anos num, correspondente a 1927-28, a Revista de História dedica alguns artigos a Oliveira Lima, falecido em Março do derradeiro ano citado. O exemplar em análise condensa algumas novidades. Desde logo, procura resgatar e edificar a memória histórica dessa personalidade, com vários discursos historiográficos que oscilam entre o testemunho pessoal e a apologia discreta e documentada. Estes relatos são extremamente fecundos porque nos revelam pormenores sobre a personalidade homenageada, mas, sobretudo, por paradoxal que pareça, acerca dos colaboradores do periódico responsáveis pelos elogios, permitindo perceber as orientações ideológicas conservadoras da publicação e o seu recorte epistemológico.

Published: July 2017

Esse artigo analisa as representações das travestis e transexuais nos discursos do jornal Lampião da Esquina entre 1978 a 1981, período de circulação do periódico. O Lampião foi um marco na defesa da diversidade sexual e de gênero durante a ditadura militar, por sua influência na construção e lutas do movimento homossexual no Brasil. O estudo dessa fonte permite, por um lado, conhecer a resistência às ações violentas do regime autoritário contra travestis/transexuais. Por outro lado, possibilita compreender como a travestilidade e a transexualidade estavam sendo representadas no imaginário de um jornal homossexual em pleno Estado de exceção no Brasil.
Um nazista na Volkswagen do Brasil: Franz Stangl e a cooperação entre militares e industriais durante a ditadura militar brasileira
Authors: Abal Felipe Cittolin
Published: July 2017

A existência de apoio ao golpe civil-militar de 1964 no Brasil por parte das elites econômicas é um fato bem explorado pela historiografia brasileira. O objetivo deste artigo é trazer à luz a existência de um esquema de vigilância dentro da fábrica da Volkswagen de São Bernardo do Campo voltada para a colaboração com o regime ditatorial militar e, especialmente, o papel de Franz Stangl, um criminoso nazista, na formatação do sistema de controle dos trabalhadores e sua execução. Stangl não se tratava meramente de um membro do partido nazista, mas sim de um ex-Comandante de dois campos de extermínio durante a Segunda Guerra Mundial, sendo responsável, direta ou indiretamente, pelo assassinato de milhares de pessoas. O aproveitamento da experiência anterior do nazista pela Volkswagen foi de utilidade para o esquema de vigilância e colaboração montado dentro da fábrica.
A Control Strategy for Combined Series-Parallel Active Filter System under Non-Periodic Conditions
Authors: M. Ucar  , S. Ozdemir  , E. Ozdemir
Published: July 2017

In this study, generalized non-active power theory based control strategy is proposed for a 3-phase 4-wire Combined Series-Parallel Active Filter (CSPAF) system using a Three-Dimensional (3D) Space Vector Pulse Width Modulation (SVPWM). The CSPAF system consists of a Series Active Filter (SAF) and a Parallel Active Filter (PAF) combination connected a common Direct Current (DC) link for simultaneous compensating the source voltage and the load current. The generalized non-active power theory was applied in previous studies for the PAF control, in this study the theory is used for the CSPAF system control under non-sinusoidal and nonperiodic current and voltage conditions. The closed loop control algorithm for the proposed CSPAF system has been described to direct control of filtering performance by measuring source currents and load voltages for the PAF and the SAF, respectively. The proposed control strategy has been verified by simulating the CSPAF system in Matlab/Simulink environment.

Published: July 2017

Hydrogen  production  is  the  main  obstacle  today to  develop  a  real  future  hydrogen  economy.  Research  has focused many efforts in extracting it from clean and renewable sources.     Different     processes     are     analysed:     photolysis, thermochemical  cycles,  algae,  etc;  these  processes  are  still  far from practical use. Electrolysis has represented the most studied and    experimented    area    for    obtaining    hydrogen    without employing fuel cracking. Nevertheless, for its practical storage, the    hydrogen    produced    at    low    pressure    needs    to    be mechanically  compressed,  with  a  high  consumption  of  electric power.   Advanced   materials   and   improved   design   allow   to obtain   hydrogen   from   electrolysis   directly   at   medium-high pressure  (70  bar)  with  no  need  of  mechanical  compression stages.  This  single-step  process  is  more  efficient  than  the  two-step  electrolysis  +  mechanical  compression  process.  In  this paper the authors display the experimental results obtained with a prototype of high pressure PEM electrolyzer manufactured by Giner  Electrochemical  Systems  LLC,  including  the  description of  the  test  bench  for  the  experimental  characterization.  The experimental    design,    based    on    Design    of    Experiments techniques,  studied  the  effect  of  the  main  operation  factors (temperature, pressure, water  flow)  at different levels of power load,  presenting  a  regression  model  of  the  electrolyzer  voltage as a  function of the operating factors, at different values of the electric load.

La evaluación del impacto potencial del CC en la AS de Aguascalientes se basa en el análisis de características edáficas y topográficas en las cuales se practica esta actividad y se complementa con el análisis de la PMA para el futuro cercano, apoyados con imágenes satelitales tipo SPOT. Los resultados indican incrementos probables en la PMA del 20 %, lo cual no necesariamente garantiza un impacto positivo en la productividad del cultivo de maíz, ya que hay factores asociados a las condiciones edáficas, topográficas y de las políticas de uso de la tierra que determinan el éxito del mismo.
How kilometric sandy shoreline undulations correlate with wave and morphology characteristics: preliminary analysis on the Atlantic coast of Africa
Authors: Idier D. , Falqués A.
Published: July 2017

Abstract. Sandy coasts are characterized by a number of rhythmic patterns like, amongst others, shoreline undulations or sandwaves at a kilometric scale. One hypothesis for their formation is that high angle waves (large incidence angle with respect to shore normal) could induce an instability of the shoreline (Ashton et al., 2001). More recently, a scaling for their wavelength has also been proposed (van den Berg et al., 2014). The existing studies rely mainly on modelling but quantitative field tests are lacking. We aim at investigating how both the formation hypothesis of these shoreline undulations and the theoretical scaling do fit with nature at a global scale. The first step, which is the goal of this paper, is to set up the methodology by analyzing the Atlantic African coast as test site. First, based on global databases, shoreline wavelength LS, wave characteristics (obliquity θW and wavelength λW) and mean shoreface slope β are determined. Then the wave obliquity is confronted with the presence of shoreline undulations. Finally the values of the ratio β LS / λW are estimated and discussed in comparison with the estimate of van den Berg et al. (2014). It is found that the correlation between shoreline sandwave occurrence and wave obliquity is very good, allowing the identification of 5 new potential unstable shoreline stretches, whereas the results on the scaling are not conclusive and deserve further investigations.

Faricimab, 6 mg (0.05 mL of a 120-mg/mL solution), administrated for neovascular age-related macular degeneration or diabetic macular edema.

Main Outcomes and Measures

The systemic and ocular histories and imaging data available were reviewed. The following were evaluated: visual acuity measured with habitual correction using the Early Treatment of Diabetic Retinopathy Study charts before and after the event; intraocular pressure; patient symptoms; anterior, intermediate, or posterior location of the intraocular inflammation; and the presence of retinal vasculitis. Multimodal imaging including color fundus photographs, fluorescein angiograms, indocyanine green angiograms, and optical coherence tomography were reviewed.

Results

A total of 12 eyes from 7 patients (mean [SD] age, 73.3 [16.7] years; 4 female [57.1%]) over 22 months were identified as having noninfectious intraocular inflammation after intravitreal faricimab injections. Among these cases, in 2 eyes, retinal vasculitis was present together with anterior and posterior inflammation. One of the 2 eyes had an occlusive form of vasculitis of the arteries and veins, leading to subsequent macular capillary nonperfusion and clinically relevant irreversible vision deterioration from 20/80 to 20/2000. The remaining eyes were characterized by moderate anterior segment inflammation without substantial vision changes. The intraocular inflammation event occurred after a median (IQR) of 3.5 (2.0-4.3) faricimab injections. The median (IQR) interval between the last faricimab injection and the diagnosis of inflammation was 28 (24-38) days. Increased intraocular pressure of 30 mm Hg or higher was found in 3 eyes.

Conclusions and Relevance

This case series highlights the occurrence of rare, but potentially severe, intraocular inflammation associated with faricimab therapy. Although these findings do not prove causality and can only generate hypotheses for future investigations, these results suggest the importance of continuous surveillance and monitoring for patients undergoing faricimab therapy to promptly identify and manage potential adverse events.

The preparation of coatings by atmospheric plasma spraying gives rise to complex physical processes, which present challenges to the study of plasma jet characteristics and particle in‐flight behavior. Herein, a 3D numerical model that integrates multiple physical phenomena, including electromagnetism and thermal and gas dynamics, to simulate the heating, acceleration, and melting of particles under the thermal–mechanical effect, is developed. Meanwhile, yttria‐stabilized zirconia (YSZ) coatings are prepared under varying process parameters. The DPV‐2000 system is employed for the diagnosis of particle velocity, surface temperature, and diameter. Following comparison, the simulation exhibits errors of 4.5% and 14.8% for the maximum temperature and velocity, respectively. An increase in current intensity from 500 to 600 A results in a rise in the proportion of particles exhibiting temperatures above the melting point (2963 K), from 75.1 to 93.4%, accompanied by an increase in average velocity of ≈16.6%. As the spraying distance increases from 60 to 100 mm, the proportion of particles melting decreases from 93.5 to 66.3%, and the average velocity decreases by ≈9.2%. This work will provide a theoretical foundation for the optimization of process parameters to adjust particle behavior and melting state, thus achieving an optimal spraying effect.

Additive manufacturing permits the precision design and meticulous fabrication of lattice structures, thereby unlocking their potential performance capabilities. Herein, to enhance the specific strength of the cubic lattice structure, three design strategies are applied: substituting solid struts with hollow ones, increasing the material proportion of vertical struts, and introducing cross plates into the hollow struts. The results demonstrate that the strategy of substituting solid struts with hollow ones effectively contributes to a substantial enhancement of 113% in the compressive yield strength of lattice structures. Furthermore, increasing the vertical material proportion from 70% to 85% while maintaining a constant relative density of 0.30, a significant enhancement is observed in both yield and ultimate strength. Additionally, introducing cross plates into the hollow struts at a vertical material proportion of 90% results in a remarkable enhancement of the specific yield strength to 230 MPa cm3 g−1, significantly surpassing that of the TC4 matrix. The optimized lattice structures exhibit exceptional uniaxial strength, tremendously exceeding the predicted limits of the Gibson–Ashby model. Thus, the Gibson–Ashby model is modified by considering the vertical material proportion Cv. These findings are expected to establish a foundational framework for the optimizing of anisotropic lattice structures by remarkably enhancing their specific strength.

Node reinforcement represents an effective strategy for enhancing the mechanical properties of lattice structures. Herein, four types of body‐centered‐cubic with Z‐strut (BCCZ) lattice structures with different node arrangements are fabricated using laser powder bed fusion (LPBF) technology. The surface morphology of four node‐reinforced BCCZ lattice structures fabricated by LPBF is examined using scanning electron microscopy. Quasistatic compression tests are conducted on these four types of node‐reinforced lattice structures. The experimental results show that the mechanical properties of all samples with node‐reinforced BCCZ lattice structures are superior to those of the traditional BCCZ lattice structure. Furthermore, the mechanical properties of the lattice structure improve in proportion to the density of the reinforced node sphere arrangement. Concurrently, an analysis of the deformation behavior of the BCCZ lattice structure with node reinforcement reveals that the TFB‐3 exhibits shear band formation at a strain level of 6.2%, which is the highest strain among all the tested structures. The results indicate that the diagonal reinforcement strategy can significantly minimize the formation of shear bands and enhance the mechanical properties of BCCZ lattice structure.

The precise manipulation of microdroplets on solid surfaces is crucial for the practical application and future development of microfluidic control technology. Traditionally, methods to achieve precise control over microdroplets often involve complex fabrication processes. Herein, the control of surface wettability is achieved based on the light‐ and heat‐responsive shape memory effect of the microstructure. An innovative superhydrophobic shape‐memory material with a simplified and efficient manufacturing process is proposed to precisely control microdroplets through surface wettability switching. Firstly, microplates with shape‐memory effects are manufactured using 4D printing technology and polylactic acid as the base material. Then, a mixture of carbon black and epoxy resin is sprayed onto the surface for superhydrophobic modification, resulting in a contact angle of up to 165°. The addition of carbon black endows the surface with excellent photothermal conversion effects. Anisotropy and photothermal response studies are incorporated. Through periodic heating, pressing, and deformation, the microplate array exhibits controllable wettability switching. Based on the shape‐memory effect of polylactic acid, the superhydrophobic surface has adjustable adhesion and is successfully applied to microfluidic platforms and microdroplet size screening. This innovative material and process offer significant potential for advancing the field of microfluidic control technology.

Rapid advancements in nano‐exfoliation and dissolution strategies have effectively disassembled hierarchical biomass materials into nanosheets, nanofibers, and even atomic‐scale molecular chains, making them highly applicable in osmotic energy harvesting. However, sub‐nanosheets, situated between molecular chains and nanofibers, remain unexplored due to the demanding nature of their preparation methods. Herein, a pseudosolvent‐driven programmable ion intercalation‐exfoliation strategy is developed that triggers exfoliation along the lowest energy crystal plane (010), as simulations confirm. This method allows for the controlled exfoliation of chitin assemblies ranging from nanofibers to sub‐nanometer sheets and molecular chains. Specifically, compared to nanofibrils, sub‐nanometer sheet interfacial assembly exhibits higher surface charge density and interplanar spacing, leading to a 2.3‐fold increase in ion transport flux while maintaining high‐performance selective ion behavior, as confirmed by both experiments and molecular scale simulations, respectively. These enhancements result in superior ionic conductivity and power conversion performance (8.45 W m−2) under a 50‐fold salinity gradient, surpassing commercial standards (5.0 W m−2) and other all‐biomass membrane systems (Max. 2.87 W m−2). This work provides insights into the controlled exfoliation of biomass at the sub‐nanometer scale and enhancing osmotic energy harvesting.

Published: October 2024

Rechargeable aqueous Zn metal batteries (RAZMBs) are considered as a competitive alternative to the next generation of energy storage system. However, the Zn stripping/plating reversibility is greatly limited by the dendrite growth and the side reactions on Zn anode. In virtue of the excellent protection and ion migration regulation effects, porous organic polymer artificial solid electrolyte interphases (POPASEIs) have attracted widespread attention in stabilizing Zn anode. This article summarizes the progress of Zn anode POPASEIs in recent years, divided into two categories according to the polymer matrix: porous polymer‐based POPASEIs and nonporous polymer‐based POPASEIs. The porous polymer‐based POPASEIs can be divided into porous coordination organic polymer (PCOOP)‐based and porous covalent organic polymers (PCVOP)‐based ASEIs according to the chemical structure, while nonporous polymer‐based POPASEIs can be divided into four types according to the pore‐forming strategies, including phase separation‐induced POPASEIs, template‐assisted POPASEIs, fiber‐formed POPASEIs, porous filler‐modified POPASEIs. In addition, the structural advantages, challenges, and perspectives of POPASEIs for Zn anode are also discussed to provide guidance for the further research and development of Zn anode ASEIs.

Orofacial clefts are the most common congenital craniofacial anomaly. Adverse healing following cleft palate repair can lead to oronasal fistula (ONF), a persistent connection between the oral and nasal cavities. Although human allograft tissues are currently the gold standard for ONF repair, these methods carry risks of infection and rejection, often requiring surgical revision. Immunoregenerative therapies present a novel alternative approach to harness the body's immune response and enhance the wound healing environment. An FDA‐approved immunomodulatory drug, FTY720, is repurposed to reduce lymphocyte egress and induce immune cell fate switching toward pro‐regenerative phenotypes. In this study, a bilayer biomaterial system is engineered using Tegaderm to secure and control the delivery of FTY720‐nanofiber scaffolds (FTY720‐NF). The release kinetics of the bilayer FTY720‐NF is optimized to maintain drug release for up to 7 days, ensuring safe transdermal absorption and tissue biodistribution. The comprehensive immunophenotyping results demonstrate a regenerative state transition in hybrid immune cells recruited to the wound site. Further, histological evaluations reveal a significant ONF closure in mice by day 7 following bilayer FTY720‐NF implantation. These findings demonstrate the utility of immunomodulatory strategies for oral wound healing, better positing the field to develop more efficacious treatment options in pediatric patients.
