Published: October 2023

O orçamento público é norteado por projeto de lei e constituído pelo Poder Executivo. O orçamento público é regido por alguns princípios que servem para garantir que os recursos arrecadados sejam aplicados de forma correta. A elaboração de planejamentos em desalinho com as reais necessidades da comunidade favorece o surgimento de créditos extraordinários que em sua maioria não atende a urgência preconizada na Constituição Federal de 1988 (CF de 1988). Quando surgem despesas que não foram previstas e que são urgentes tais como as provenientes de guerra, comoção interna ou calamidade pública o Poder Executivo através de Medidas Provisórias lança mão dos créditos extraordinários. O artigo procurou responder ao seguinte questionamento: Qual a relação existente entre planejamento orçamentário e créditos extraordinários no Brasil? Teve como objetivo geral norteador da pesquisa analisar a relação existente entre planejamento orçamentário e créditos extraordinários no Brasil, utilizando como base à literatura sobre a temática. A metodologia empregada foi bibliográfica, documental e descritiva. Buscou através da literatura abordar assuntos tais como: orçamento público, planejamento, princípios e créditos orçamentários. Teve como autores para o embasamento teórico Paludo (2017), Albuquerque (2022) e a Constituição Federal de 1988. Por fim, conclui que o processo de abertura de crédito extraordinários de maneira geral, poderá ser aperfeiçoado, observando a reflexão realizada acerca do objetivo final, bem como, da cerne do controle da execução do orçamento, de maneira a se tornar menos propenso à influência de interesses políticos ou ocorrências de possíveis fraudes, buscando-se elaborar planejamento orçamentários eficazes.

The present investigation was carried out to evaluate the extent of genetic diversity and variability existing among the twenty two fine grain rice genotypes under study for eight significant yield attributes. Genetic diversity analysis based on D2 values suggested the grouping of 22 genotypes into eight clusters with genotypes in varying numbers. The biggest cluster, Cluster I, consisted eight genotypes succeeded by cluster II with 5 and cluster III with 3 genotypes. Distance within cluster was maximum in cluster V followed by the clusters II, III and I. Cluster III showed highest inter-cluster distance with cluster VII and cluster VIII. The traits single plant yield, grains per panicle, plant height and spikelet fertility contributed 94.8 per cent towards total divergence. Hence, these characters warrant maximum attention in hybridization programme and also during selection in the segregating generations. Simple selection procedures may be employed for characters viz., single plant yield, productive tillers per plant, filled grains per panicle and hundred seed weight with high and moderate extent of PCV and GCV. The characters single plant yield, filled grain per panicle and hundred seed weight showing the prevalence of high heritability along with high genetic advance as per cent of mean which reveals the presence of additive genetic effect.
Improved Range of Motion and Decreased Complications After Total Knee Arthroplasty with Use of Plethy Recupe Remote Patient Monitoring: A Retrospective Study
Authors: Hui Timothy , Greene Hunter , Sasaura Paul , Subramanian Subu , Sharew Bereket Ayalneh , Woldebirhan Yordanos 
Published: October 2023

Background: Home exercise plans (HEP) are key to recovery from surgeries, but poor compliance limits benefits. Digital health shows promise in improving compliance. This retrospective study compared pain, range of motion (ROM), and manipulation under anesthesia (MUA) complications after a total knee arthroplasty (TKA) from one clinic where one group used digital health and another did not.
Methods: Patient population was all TKA patients from 9/1/21 to 4/30/22. For rehabilitation, 41 patients used Recupe, a digital app that instructs and monitors home exercises along with live coaching. 95 patients did not. Age, gender, and BMI between both groups were very similar.
Results: ROM improved significantly with the use of Recupe, improving to 120 degrees after 1 month – a key ROM for function. The non-Recupe group improved to 112 degrees in the same timeframe.
The need for MUA was significantly better for the Recupe group, where 2% required MUA versus 5% for the other group, indicating a lower risk of major complications.
Pain averaged 2.34/10 for the Recupe group after 1 month versus 2.86/10 for the non-Recupe group, though not statistically significant.
The Recupe group performed their exercises an average of 5.1 times per week.
Conclusions: The Recupe group and the Non-Recupe group both attended medical and physical therapy visits, so the significant differences in results are likely due to non-adherence of HEP by the Non-Recupe group. This suggests that lengthened musculoskeletal recovery amongst workers may be due to non-adherence to prescribed care plans, and that digital health may improve their compliance.
Use of Recupe during rehabilitation after a Total Knee Arthroplasty results in significantly faster ROM improvement and significantly decreased risk of Manipulation Under Anesthesia. Pain was also decreased though not to statistical significance.

Published: October 2023

AbstractOxide solid electrolytes are attractive for the implementation of solid‐state Li‐ion batteries. However, constrained by the large ion‐transport hindrance inside the densely packed lattice, their Li‐ion conductivity can hardly reach the level of liquid electrolytes. A strategy of introducing confined water into the lattice paves a new way for enhancing the Li‐ion transport, which has been reported in the previous studies. To further verify the universality of this strategy and unravel the facilitation mechanism, here this work establishes an ideal model using Li‐H‐Cl‐O quaternary compounds with a wide electrochemical stability window. As a major kind of confined water, the content and type of ─OH groups are crucial parameters affecting the Li‐ion conductivity. Through a controllable dehydration technique, the hydrogen‐bonded ─OH groups can be mostly removed, leaving the free ─OH groups in lattice, which is beneficial to the increase of free volume and acceleration of rotation response. The 1–2 orders of magnitude enhancement of Li‐ion conductivity ensures full cells good rate and cycling performance. This work not only addresses the controversy in Li‐H‐Cl‐O about the hydrogen effect on Li‐ion transport, but also provides detailed theoretical insights for the rational design of solid electrolytes.

Published: October 2023

AbstractFlexible sensors, as a significant component of flexible electronics, have attracted great interest the realms of human–computer interaction and health monitoring due to their high conformability, adjustable sensitivity, and excellent durability. In comparison to wearable sensor‐based in vitro health monitoring, the use of implantable flexible sensors (IFSs) for in vivo health monitoring offers more accurate and reliable vital sign information due to their ability to adapt and directly integrate with human tissue. IFSs show tremendous promise in the field of health monitoring, with unique advantages such as robust signal reading capabilities, lightweight design, flexibility, and biocompatibility. Herein, a review of IFSs for vital signs monitoring is detailly provided, highlighting the essential conditions for in vivo applications. As the prerequisites of IFSs, the stretchability and wireless self‐powered properties of the sensor are discussed, with a special attention paid to the sensing materials which can maintain prominent biosafety (i.e., biocompatibility, biodegradability, bioresorbability). Furthermore, the applications of IFSs monitoring various parts of the body are described in detail, with a summary in brain monitoring, eye monitoring, and blood monitoring. Finally, the challenges as well as opportunities in the development of next‐generation IFSs are presented.

Published: October 2023

AbstractTitanium dioxide (TiO2) stands out as a versatile transition‐metal oxide with applications ranging from energy conversion/storage and environmental remediation to sensors and optoelectronics. While extensively researched for these emerging applications, TiO2 has also achieved commercial success in various fields including paints, inks, pharmaceuticals, food additives, and advanced medicine. Thanks to the tunability of their structural, morphological, optical, and electronic characteristics, TiO2 nanomaterials are among the most researched engineering materials. Besides these inherent advantages, the low cost, low toxicity, and biocompatibility of TiO2 nanomaterials position them as a sustainable choice of functional materials for energy conversion. Although TiO2 is a classical photocatalyst well‐known for its structural stability and high surface activity, TiO2‐based photocatalysis is still an active area of research particularly in the context of catalyzing artificial photosynthesis. This review provides a comprehensive overview of the latest developments and emerging trends in TiO2 heterostructures and hybrids for artificial photosynthesis. It begins by discussing the common synthesis methods for TiO2 nanomaterials, including hydrothermal synthesis and sol–gel synthesis. It then delves into TiO2 nanomaterials and their photocatalytic mechanisms, highlighting the key advancements that have been made in recent years. The strategies to enhance the photocatalytic efficiency of TiO2, including surface modification, doping modulation, heterojunction construction, and synergy of composite materials, with a specific emphasis on their applications in artificial photosynthesis, are discussed. TiO2‐based heterostructures and hybrids present exciting opportunities for catalyzing solar fuel production, organic degradation, and CO2 reduction via artificial photosynthesis. This review offers an overview of the latest trends and advancements, while also highlighting the ongoing challenges and prospects for future developments in this classical yet rapidly evolving field.

Published: October 2023

AbstractThe ternary cathode material LiNi0.8Co0.1Mn0.1O2 is widely used in lithium batteries, and the sintering process plays a crucial role in its production. Proper configuration of sintering kiln parameters directly affects the quality of LiNi0.8Co0.1Mn0.1O2. However, determining optimal working conditions through onsite trials is time‐consuming and expensive. A predictive model for the sintering furnace of ternary cathode material is developed. The predictive model incorporates chemical reactions, thermal conduction inside the saggars, and convective and radiative heat transfer within the furnace. It comprehensively analyzes the relationship between furnace temperature and material temperature. Radiative heat transfer within the furnace is calculated using the Monte Carlo method, and convective heat transfer properties on the surface of the saggars are obtained through computational fluid dynamics simulations. Heat transfer inside the saggars is resolved using the finite difference method. The model accounts for the effects of operational and structural parameters. Onsite experiments validate the accuracy of the model, with a simulation error of <±10% under typical working conditions. Leveraging this model, the effects of loading quantity, moving velocity, and saggar size on the sintering of ternary cathode materials are compared. Optimization recommendations are proposed to enhance production capacity.
The impact of old‐age pension on nutritional outcomes: Evidence from Kyrgyzstan

Published: October 2023

AbstractExtensive studies have discussed the economic and welfare effects of social pensions worldwide, while scant attention has been paid to their nutritional effects, especially in emerging economies. Using multitopic longitudinal survey data of households and individuals in Kyrgyzstan covering four waves of 2012, 2013, 2016, and 2019, this study aims to examine the impact of an old‐age pension on the nutritional outcomes of the elderly and shed light on their underlying mechanisms. Our empirical identification rests on a propensity score matching with difference‐in‐differences estimation design to address the endogeneity problem of receiving an old‐age pension. Overall, the results indicate that receiving an old‐age pension has a significant and negative impact on body mass index and the probability of being overweight for males, while no significant impact of the old‐age pension has been observed for females. Receiving an old‐age pension has no significant effect on expenditure of food consumption, calorie intake, and macronutrient intake, while it significantly reduces the ratio of protein intake to total calorie intake. We also observe significant heterogeneity in the nutritional effect of an old‐age pension across various education levels and income levels; the negative nutritional effect is more salient for elderly individuals who are relatively poor or who have lower education. Our findings provide profound implications for policies targeting improving the nutritional status of rural residents in emerging economies through the implementation of the old‐age pension [EconLit Citations: H55, I15, I38].

Published: October 2023

AbstractA copper‐catalyzed dearomative alkynylation of pyridines is reported with excellent regio‐ and enantioselectivities. The synthetically valuable enantioenriched 2‐alkynyl‐1,2‐dihydropyridine products afforded are generated from the readily available feedstock, pyridine, and commercially available terminal alkynes. The three‐component reaction between a pyridine, a terminal alkyne, and methyl chloroformate employs copper chloride and StackPhos, a chiral biaryl P,N‐ ligand, as the catalytic system. Under mild reaction conditions, the desired 1,2‐addition products are delivered in up to 99 % yield with regioselectivity ratios up to 25 : 1 and enantioselectivities values of up to 99 % ee. Activated and non‐activated terminal alkynes containing a wide range of functional groups are well tolerated. Even acetylene gas delivered mono‐alkynylated products in high yield and ee. Application of the methodology in an efficient enantioselective synthesis of the chiral piperidine indolizidine, coniceine, is reported.

Published: October 2023

AbstractHerein, we report an unprecedented copper‐catalyzed highly enantio‐ and diastereoselective radical oxyboration of β‐substituted styrenes. The lynchpin of success is ascribed to the development of a late‐stage stereomutation strategy, which enables enantioenriched cis‐isomers among a couple of early‐generated diastereomers to be converted into trans‐isomer counterparts, thus fulfilling high diastereocontrol; while the degree of enantio‐differentiation is determined by the borocupration process of the C=C bond. This reaction provides an efficient protocol to access enantioenriched trans‐1,2‐ dioxygenation products. The value of this method has further been highlighted in a diversity of follow‐up stereospecific transformations and further modifying complex molecules.

AbstractCreation of intrapenetrated mesopores with open highway from external surface into the interior of zeolite crystals are highly desirable that can significantly improve the molecular transport and active sites accessibility of microporous zeolites to afford enhanced catalytic properties. Here, different from traditional zeolite‐seeded methods that generally produced isolated mesopores in zeolites, nanosized amorphous protozeolites with embryo structure of zeolites were used as seeds for the construction of single‐crystalline hierarchical ZSM‐5 zeolites with intrapenetrated mesopores (mesopore volume of 0.51 cm3 g−1) and highly complete framework. In this strategy, in contrast to the conventional synthesis, only a small amount of organic structure directing agents and a low crystallization temperature were adopted to promise the protozeolites as the dominant growth directing sites to induce crystallization. The protozeolite nanoseeds provided abundant nucleation sites for surrounding precursors to be crystallized, followed by oriented coalescence of crystallites resulting in the formation of intrapenetrated mesopores. The as‐prepared hierarchical ZSM‐5 zeolites exhibited ultra‐long lifetime of 443.9 hours and a high propylene selectivity of 47.92 % at a WHSV of 2 h−1 in the methanol‐to‐propylene reaction. This work provides a facile protozeolite‐seeded strategy for the synthesis of intrapenetrated hierarchical zeolites that are highly effective for catalytic applications.

Published: October 2023

AbstractA series of [2]catenanes has been prepared from di‐NHC building blocks by utilizing solvophobic effects and/or π⋅⋅⋅π stacking interactions. The dinickel naphthobiscarbene complex syn‐[1] and the kinked biphenyl‐bridged bipyridyl ligand L2 yield the [2]catenane [2‐IL](OTf)4 by self‐assembly. Solvophobic effects are pivotal for the formation of the interlocked species. Substitution of the biphenyl‐linker in L2 for a pyromellitic diimide group gave ligand L3, which yielded in combination with syn‐[1] the [2]catenane [3‐IL](OTf)4. This assembly exhibits enhanced stability in diluted solution, aided by additional π⋅⋅⋅π stacking interactions. The π⋅⋅⋅π stacking was augmented by the introduction of a pyrene bridge between two NHC donors in ligand L4. Di‐NHC precursor H2‐L4(PF6)2 reacts with Ag2O to give the [Ag2L42]2 [2]catenane [4‐IL](PF6)4, which shows strong π⋅⋅⋅π stacking interactions between the pyrene groups. This assembly was readily converted into the [Au2L42]2 gold species [5‐IL](PF6)4, which exhibits exceptional stability based on the strong π⋅⋅⋅π stacking interactions and the enhanced stability of the Au‐CNHC bonds.

Published: October 2023

AbstractInformation security has gained increasing attention in the past decade, leading to the development of advanced materials for anti‐counterfeiting, encryption and instantaneous information display. However, it remains challenging to achieve high information security with simple encryption procedures and low‐energy stimuli. Herein, a series of strain/temperature‐responsive liquid crystal elastomers (LCEs) are developed to achieve dual‐modal, multi‐level information encryption and real‐time, rewritable transient information display. The as‐prepared polydomain LCEs can change from an opaque state to a transparent state under strain or temperature stimuli, with the transition strains or temperatures highly dependent on the concentration of long‐chain flexible spacers. Information encrypted by different LCE inks can be decrypted under specific strains or temperatures, leading to multi‐level protection of information security. Furthermore, with the combination of the phase transition of polydomain LCEs and the photothermal effect of multi‐walled carbon nanotubes (MWCNTs), we achieved a repeatable transient information display by using near‐infrared (NIR) light as a pen for writing. This study provides new insight into the development of advanced encryption materials with versatility and high security for broad applications.
Über die Detonationsgeschwindigkeit des Methans und Dizyans im Gemisch mit Sauerstoff und Stickstoff
Authors: Döring W. , Schön G. 
Published: October 2023

AbstractDie Detonationsgeschwindigkeiten einiger Gemische des Methans und Dizyans mit Sauerstoff und Stickstoff, welche von Dixon gemessen wurden, werden unter Berücksichtigung der Dissoziation der Gase in den Schwaden berechnet. Es wird gezeigt, daß die beobachtete Abnahme der Detonationsgeschwindigkeit mit wachsendem Sauerstoffgehalt und ihre geringe Änderung beim Ersetzen eines Teiles des Sauerstoffes durch Stickstoff nicht von der unvollständigen Erreichung des chemischen Gleichgewichtes in der Reaktionszone herrührt, sondern auf die verschiedenartigen Einflüsse der Dissoziation des Kohlendioxyds, des Sauerstoffes und des Stickstoffes zurückzuführen ist. An Hand eines ins einzelne gehenden Bildes von der Struktur der Reaktionszone werden die Abweichungen zwischen den theoretischen und experimentellen Ergebnissen qualitativ gedeutet.
Über den Reaktionsmechanismus der Kohleverbrennung bei Atmosphärendruck
Authors: Baetke F. W. 
Published: October 2023

AbstractBei hoher Strömungsgeschwindigkeit (30–100 m/sec) lieferten Verbrennungsversuche mit trockner, durch Kohlekanäle gesaugter Luft im Abgas hauptsächlich CO neben unverbrauchtem Sauerstoff. Verminderter Gesamtdruck oder Halogenzusatz ergaben Abgase mit relativen CO‐Ausbeuten pCO/ (PCO+PCO2) von 0,9 bis 0,95.Es wird daher angenommen, daß bei Atmosphärendruck primär Kohlenoxyd gebildet wird. Dieses kann unter bestimmten Versuchsbedingungen auch bei geringeren Strömungsgeschwindigkeiten unverbrannt im Abgas erhalten werden.
