A ESCOLA NORMAL OFICIAL DE PERNAMBUCO: ESTRATÉGIAS E TÁTICAS DE PRODUÇÃO DA “DOCÊNCIA ESCOLARIZADA” ENTRE OS ANOS DE 1864 E 1880
Authors: Lima Dayana Raquel Pereira de 
Published: August 2023

Este texto pretende analisar as estratégias e táticas de formação e certificação docente concedida pela Escola Normal Oficial de Pernambuco (Brasil) entre 1864 e 1880. Por intermédio da transcrição simples, direta e completa (ARÓSTEGUI, 2006) dos registros documentais nos Anais da Assembleia de Pernambuco, nas petições remetidas aos deputados provinciais, nos regulamentos da Escola Normal, nas legislações e relatórios da instrução pública, bem como em algumas revistas, mobilizou-se as categorias “experiência” (THOMPSON, 1981), “táticas” e “estratégias” (DE CERTEAU, 1994), visando tecer as maneiras pelas quais as autoridades governamentais, os alunos e alunas normalistas e os docentes públicos primários pernambucanos, em função de suas posições, construíram significações com relação à produção da “docência escolarizada” – formação de docentes para atuarem no magistério público primário – promovida pela Escola Normal. Conclui-se que, de meados da década de 1860 até os anos 1880, a Escola Normal de Pernambuco passou de alternativa indispensável para uma formação com rigor e qualidade teórico, prático e moral da docência pública primária para um lugar cujas práticas internas e externas eram comandadas por politicagens, ou denunciadas, ou abafadas pelo poder público, professores e professoras, alunos e alunas. Os códigos práticos do ofício, há muito conhecidos e aplicados nas práticas de escolarização da sociedade pernambucana (SILVA, 2007) atravessaram e constituíram a formação institucionalizada da docência pública primária no Pernambuco da segunda metade do século XIX.

Abstract
Objectives
The public health impact of nicotine vaping products (NVPs) is subject to complex transitions between NVP and cigarette use. To circumvent the data limitations and parameter instability challenges in modeling transitions, we indirectly estimate NVPs’ impact on smoking prevalence and resulting smoking-attributable deaths using the SimSmoke simulation model.

Methods
Canada SimSmoke uses age- and sex-specific data on Canadian population, smoking prevalence and tobacco control policies. The model incorporates the impact of cigarette-oriented policies on smoking prevalence but not the explicit contribution of NVPs. The model was calibrated from 1999 to 2012, thereby projecting smoking prevalence before NVPs were widely used in Canada. The NVP impact on smoking prevalence is inferred by comparing projected 2012–2020 smoking trends absent NVPs to corresponding trends from two Canadian national surveys. We further distinguish impacts before and after NVPs became regulated in 2018 and more available.

Results
Comparing 2012–2020 survey data of post-NVP to SimSmoke projected smoking prevalence trends, one survey indicated an NVP-related relative reduction of 15% (15%) for males (females) age 15+, but 32% (52%) for those ages 15–24. The other survey indicated a 14% (19%) NVP-related smoking reduction for ages 18+, but 42% (53%) for persons ages 18–24. Much of the gain occurred since Canada relaxed NVP restrictions. NVP-related 2012–2020 smoking reductions yielded 100,000 smoking-attributable deaths averted from 2012 to 2060.

Conclusion
Smoking prevalence in Canada, especially among younger adults, declined more rapidly once NVPs became readily available. The emergence of NVPs into the Canadian marketplace has not slowed the decline in smoking.

Aquaculture activities with floating net cages are essential to increase fishery production. However, The fish cages in the Jatigede Reservoir are illegal because they are against local government regulations. However, the people affected by the dam's construction still maintain it for economic reasons. Therefore, it is necessary to conduct research to address these problems by determining the carrying capacity of aquaculture and evaluating the trophic status of the waters. Determination of the carrying capacity of fish farming in the Jatigede Reservoir was conducted using the Beveridge method. by calculating the remaining phosphorus still available in the Jatigede Reservoir and evaluating the trophic state index based on three indicators: transparency, total phosphorus, and chlorophyll-a. The sampling was carried out by purposive sampling method. The calculation results show that the condition of the Jatigede Reservoir was eutrophic to hypertrophic with a trophic state index (TSI) value of 66-71.

ABSTRAK

Kegiatan budidaya dengan keramba jaring apung (KJA) sangat penting untuk meningkatkan produksi perikanan. Keberadaan KJA di Waduk Jatigede merupakan kegiatan ilegal karena bertentangan dengan peraturan pemerintah setempat. Namun, masyarakat yang terkena dampak pembangunan waduk tetap mempertahankannya karena alasan ekonomi. Oleh karena itu, perlu dilakukan penelitian untuk mengatasi permasalahan tersebut dengan menentukan daya dukung perikanan budidaya dan mengevaluasi status trofik perairan. Penentuan daya dukung budidaya ikan di Waduk Jatigede dilakukan dengan menggunakan metode Beveridge dengan menghitung sisa fosfor yang masih tersedia di Waduk Jatigede dan mengevaluasi indeks status trofik berdasarkan tiga indikator yaitu transparansi, total fosfor, dan klorofil-a.

Published: August 2023

Ensuring uninterrupted navigation on the Danube River and the shortest exit to the Black Sea is a priority direction for the implementation of the seventh international transport corridor, which unites the countries of Europe and Asia. For this purpose, the protection dam of the Marine channel of the Danube-Black Sea deep-sea passage was built, which was partially destroyed by storm waves and ice load. This made it necessary to carry out scientific researches in order to strengthen the operational stability of the dam and ensure its effective use. The paper presents the results of numerical and physical simulation of the interaction of waves with the protective dam of the Marine channel of the Danube-Black Sea and loads on the dam structure. Mathematical simulation was performed using the SWAN refraction and spectral model, as well as the XBeach model. Experimental research was carried out in laboratory conditions in a wave channel. The estimated distribution of the wave field near the dam under storm surge conditions was obtained and the space-time characteristics of wave pressure fluctuations on the streamlined surface of the protective dam model were determined. Integral and spectral characteristics of the pressure fluctuation field were obtained and a multi-stage form of a dam with two berms was proposed, which significantly reduced the wave load and was resistant to storm waves. The berms performed the functions of underwater breakwaters and significantly reduced the energy of the wave impact on the upper part of the dam. The optimal shape of the dam and the geometric parameters of its frontal surface were determined. It is proposed to build the seaward part of the protective dam under natural conditions with the following parameters: a lower deep-water slope with a slope of 1 : 1,5, then at a depth of 4 m a lower berm with a width of 10 m. Then make a slope with a slope of 1 : 5, and then at a depth of 2 m to install an upper berm with a width of 10 m. It is recommended to finish the protective dam of the Marine channel of the Danube-Black Sea deep-sea passage with a ridge with a slope of 1 : (3 – 3,5). The facing of the frontal part of the dam should be made of stone overburden with stones of fraction 1,2 m.
NUMERICAL SIMULATION OF THE FLOW AROUND AN AIRFOIL TYPE TRANSPORT VEHICLE NEAR THE GROUND
Authors: Sokhatsky Anatoly 
Published: August 2023

The problem of modeling the flow around an airfoil type transport vehicle near the ground is considered. The flow around the vehicle is turbulent. Nowadays, the most advanced mathematical models of aerodynamics are based on the physical properties of a viscous compressible gas and are based on the Reynolds-averaged Navier – Stokes equations. Mathematical modeling of turbulent flows remains one of the most challenging problems. Reliable prediction of the characteristics of turbulent flows is an extremely important scientific problem. This is due to the complexity and insufficient study of turbulence as a physical phenomenon. The aim of this work is to build a mathematical model, a numerical method, an algorithm for solving the problem, and to develop software for studying the aerodynamic characteristics of a vehicle of the airfoil type. To close the Reynolds-averaged Navier –Stokes equations, the one-parameter Spalart – Allmaras turbulence model was used. The initial system of differential equations is written in a curved coordinate system. The initial and boundary conditions for the flow parameters are formulated. The methodology, algorithm for solving the problem, and software are developed. The finite-volume method was used for numerical integration of the system of differential equations. The problem was solved in a multi-block formulation. The developed methodology of algorithms and a set of programs were tested on standard aerodynamic problems: the flow around a transversely placed circular cylinder and a ball. Numerical modeling of the flow of compressed gas around a vehicle moving near the ground was performed. All calculations were carried out for the Reynolds number Re=1,0*10^6 and the Mach number M=0,4. Numerical simulations were performed on a curved multi-block grid. The influence of the ground on the characteristics of the flow around the vehicle was investigated. The studies have shown that the presence of a nearby ground has a significant impact on the flow characteristics around the vehicle. Thus, in order to ensure the required parameters of vehicle dynamics near the ground, it is necessary to take into account the influence of the ground on its aerodynamic characteristics.
Overflush and Hydraulic Fracturing: Playing Poker with Your Completion
Authors: Rylance Martin 
Published: August 2023

Summary
Since the inception of hydraulic fracturing, the industry has wrestled with the concept of over-/underflushing and has always pitched this as a binary philosophy, attempting to determine/define whether this is either a fundamentally good or a bad approach. This schism simply grew with the extensive development of unconventionals; the use of overflush being an inherent and fundamental requirement for an effective and economic unconventional completion sequence. This paper will demonstrate that the true answer, as any engineer would expect, is that a detailed assessment is what is required on a case-by-case basis.
The paper will describe and reference several fracturing case histories in both the conventional and unconventional environments where the application of an overflush, an underflush, or an engineered approach has been assessed or applied. Rather than taking an easy headline grabbing route to perpetuate the myth that the process is a major paradigm or simply either a good or a bad thing, this paper will discuss some of the key aspects that impact the suitability of one approach over another and how engineering the implementation can lead to a broader range of applicability/suitability for the most economically effective outcome. This includes an appreciation of the production/economic profile and exposure to risk, which are hugely different in, say, an ultradeep-water five well offshore development vs. a field development with some 100s to 1,000s of wells in a lower-cost onshore environment.
The paper will describe and demonstrate some of the fundamental variables that need to be considered, attempting to elaborate on a few of the key parameters that can influence the effective outcome. The paper will also indicate that there are several different scenarios whereby any form of overflush can result in a detrimental impact on the production rate and estimated ultimate recovery (EUR) and that these must be fully appreciated. Subtleties, related to reservoir characteristics and fracture geometry, should be examined and appreciated. Additional aspects such as how production, drawdown, and pore pressure will be managed can also have an impact. All these considerations, and more, will be discussed, described, and referenced.
While there is no doubt that the overflush debate will continue unabated, the intent of this paper is to reduce the damage (or uncertainty), one way or the other, that will result. It is an attempt, at a minimum, to ensure that the debate becomes solely a technical one related to the approaches to be taken rather than a black and white one of right or wrong. Ultimately, the paper will advise, and inform, that the approach should be fully considered, engineered in detail and tailored to each, and every application and that as a result is no longer simply considered a binary question.
Multiparameter Inversion of Reservoirs Based on Deep Learning

Published: August 2023

Summary
Reservoir parameter inversion is an important technique in oil and gas exploration and development that can estimate the reservoir physical properties, such as skin factor and permeability, using observed data, such as well test data and production data. In this paper, we propose a physical accelerated neural network with multiple residual blocks (PRNN-Acc) for multiple parameter inversion of the seepage equation with a source term and a sink term. PRNN-Acc is based on the idea of physical residual neural network (PRNN), which uses deep neural networks to approximate the solution and parameter spaces of partial differential equations. PRNN-Acc adds multiple residual blocks to enhance the expression ability and flexibility of the network and avoid gradient explosion or degeneration phenomena. In addition, the input of PRNN-Acc is multiplied by three adaptive parameters, which can adjust the network training process according to the characteristics of the data and loss function and improve the accuracy and stability of the inversion. We use bottomhole pressure (BHP) data before and after shut-in as labels to invert multiple parameters for homogeneous and heterogeneous reservoirs. In this paper, three numerical experiments are designed. For homogeneous and heterogeneous reservoirs, the inversion results of this method are up to 36 times more accurate than those of PRNN. It is fully proven that the inversion effect of this method is better than that of PRNN.
Rapid sea level rise causes loss of seagrass meadows

Published: August 2023

Abstract
As global declines in seagrass populations continue to cause great concern, long-term assessment of seagrass meadows show promise in providing valuable insights into fundamental causes of seagrass loss and drivers of environmental change. Here we report two long-term records of seagrass presence in western Gulf of Mexico coastal waters that provided insight into their rapid decline in a relatively pristine ecosystem. Coincident with unprecedented increases in water depth starting in 2014 (14-25 mm y-1), monthly measurements at a “deep edge” fixed station revealed that two ubiquitous seagrass species (Halodule wrightii and Syringodium filiforme) vanished altogether in just five years; a subsequent basin wide assessment revealed that seagrasses disappeared at 23% of 144 sentinel stations. Models that incorporate differing sea level rise scenarios and water depth thresholds reveal additional global losses of seagrass habitat (14,000 km2), with expansion into newly created shallow habitats further exacerbated by hardened shorelines

Abstract

DNA double-strand breaks (DSBs), such as those produced by radiation and radiomimetics, are amongst the most toxic forms of cellular damage, in part because they involve extensive oxidative modifications at the break termini. Prior to completion of DSB repair, the chemically modified termini must be removed. Various DNA processing enzymes have been implicated in the processing of these ‘dirty ends’, but molecular knowledge of this process is limited. Here, we demonstrate a role for the metallo-β-lactamase fold 5′-3′ exonuclease SNM1A in this vital process. Cells disrupted for SNM1A manifest increased sensitivity to radiation and radiomimetic agents and show defects in DSB damage repair. SNM1A is recruited and is retained at the sites of DSB damage via the concerted action of its three highly conserved PBZ, PIP box and UBZ interaction domains, which mediate interactions with poly-ADP-ribose chains, PCNA and the ubiquitinated form of PCNA, respectively. SNM1A can resect DNA containing oxidative lesions induced by radiation damage at break termini. The combined results reveal a crucial role for SNM1A to digest chemically modified DNA during the repair of DSBs and imply that the catalytic domain of SNM1A is an attractive target for potentiation of radiotherapy.

Abstract

BACKGROUND
Over the years, therapeutic application of plants has been used in folkloric medicine to explore natural alternatives to usage of antibiotic growth promoters due to the development of resistant bacteria strains and presence of drug residues in poultry meat. This study investigated the effects of concentrations and frequencies of administration of Lagenaria breviflora fruit extract (LBFE) on the haematological indices and carcass yield of broiler chickens. 390 birds were randomly distributed into 8 treatments; T1: control, T2: 75 g of LBFE/litre as synthetic antibiotic replacer (SAR) when necessary, T3: 75 g of LBFE/litre for 3days/week, T4: 75 g of LBFE/litre for 5days/week, T5: control, T6: 125 g of LBFE/litre as SAR, T7: 125 g of LBFE/litre for 3days/week and T8: 125 g of LBFE/litre for 5days/week. The experiment was laid out in a 2×4 factorial and data were subjected to Completely Randomized Design. Packed cell volume (PCV), red blood cell count (RBC), white blood cell count (WBC) and haemoglobin (HB) were determined using improved Neubaur Haemycytometer after dilution and Cyanomethamoglobin methods. Dressing percentage for the carcass yield were also obtained.
RESULTS
Eosinophil counts and Uric acid were significantly (p < 0.05) highest in birds administered 75 g of LBFE/ litre of water 5days/week. At the finisher phase, Packed cell volume was significantly (P < 0.05) highest (32.25) in birds administered 75 g of LBFE/ litre of water 5days/week, while birds administered 125 g of LBFE/ litre of water as antibiotic replacement had significantly (P < 0.05) highest (5.00) red blood cell count. The thigh and liver of birds administered LBFE 3 days/week had the highest values (P < 0.5) of 10.79% and 2.84% respectively.
CONCLUSION
The study infers that administration of LBFE to broilers enhances the haematological indices as well as carcass yield which ultimately promotes healthy living of the birds.

Published: August 2023

Abstract
The testing and measurement of dynamic transmission error in cone gears is highly challenging in oil-based environments, where conventional testing methods are often limited in scope. To address this issue, a testing method utilizing strain sensors was proposed to measure dynamic transmission error in cone gears. To verify the feasibility of this testing method, a testing platform was designed and constructed specifically for cone gear transmission error testing. During the testing process, temperature-induced interference was compensated using a quarter-bridge configuration to enhance the reliability of test data. Additionally, a magnetic grid method was used to synchronously measure dynamic transmission error in cone gears. Comparative analysis of test results from the two different testing methods was conducted under various operational conditions of the cone gears. The comparison successfully verified the feasibility of the stress-strain-stiffness method in measuring dynamic transmission error in cone gears. This study provides a new, quick, simple, and practical testing method for measuring dynamic transmission error in cone gears, which can be valuable for academic research and practical applications.
