DESESTABILIZANDO UNA ECONOMÍA INESTABLE: ¿NUEVO PAPEL DE LA BANCA CENTRAL?
Authors: Combita Mora Gonzalo , Ortiz Sierra Gilberto
Published: July 2023

Este trabajo pretende demostrar que la actual crisis bancaria que se ha presentado en Estados Unidos no es un evento aislado ni coyuntural, sino que es el más reciente acontecimiento de una continua serie de ciclos de fragilidad financiera ocasionada por el manejo conservador de la política monetaria de la Reserva Federal desde 1965. Para esto realizamos un análisis teórico y descriptivo crítico que muestra el impacto de la Reserva Federal sobre la valoración cíclica de los portafolios en Estados Unidos y también el efecto adverso en la dinámica macroeconómica de América Latina desde 1980. La conclusión es que la fragilidad financiera creciente de los balances de los agentes durante el auge provoca que las medidas de control inflacionario mediante la tasa de interés tengan un efecto incluso permanente en la economía.
 
DESTABILIZING AN UNSTABLE ECONOMY: A NEW ROLE FOR CENTRAL BANKING?
ABSTRACT
The aim of this paper is to demonstrate that the current banking crisis in the United States is not an isolated or conjunctural event, but rather the most recent event in a continuous series of cycles of financial fragility caused by the conservative management of the Federal Reserve’s monetary policy since 1965. For this purpose, a critical theoretical and descriptive analysis is carried out, showing the impact of the Federal Reserve on the cyclical valuation of portfolios in the United States and also the adverse effect on the macroeconomic dynamics of Latin America since 1980. The conclusion is that the increasing financial fragility of agents’ balance sheets during the boom causes inflationary control measures through the interest rate to have an adverse permanent effect on the economy.

Published: July 2023

Background: The current paradigms in arterial blood gas analysis are based on mathematical or physicochemical models that require complex algorithms for interpretation. This leads to avoidance or dislike from health care professionals.
Purpose: To formulate a new approach to the analysis and classification of acid base disturbances.
Methodology: we conducted a systematic review of the related literature and a paradigm shift for data interpretation.
Results: Acid-base disorders can be grouped and managed according to the underlying biochemical processes.
Conclusions: This proposal represents a new classification, which groups acid base disorders according to the underlying causal biochemical process. Disorders with an elevated anion gap relate to alterations in cellular respiration (energy/ATP production)- All disturbances with  normal anion gap relate to transmembrane ion exchange.
Limitations of the Macaulay matrix approach for using the HHL algorithm to solve multivariate polynomial systems
Authors: Ding Jintai , Gheorghiu Vlad , Gilyén András , Hallgren Sean , Li Jianqiang
Published: July 2023

Recently Chen and Gao \cite{ChenGao2017} proposed a new quantum algorithm for Boolean polynomial system solving, motivated by the cryptanalysis of some post-quantum cryptosystems. The key idea of their approach is to apply a Quantum Linear System (QLS) algorithm to a Macaulay linear system over C, which is derived from the Boolean polynomial system. The efficiency of their algorithm depends on the condition number of the Macaulay matrix. In this paper, we give a strong lower bound on the condition number as a function of the Hamming weight of the Boolean solution, and show that in many (if not all) cases a Grover-based exhaustive search algorithm outperforms their algorithm. Then, we improve upon Chen and Gao's algorithm by introducing the Boolean Macaulay linear system over C by reducing the original Macaulay linear system. This improved algorithm could potentially significantly outperform the brute-force algorithm, when the Hamming weight of the solution is logarithmic in the number of Boolean variables.Furthermore, we provide a simple and more elementary proof of correctness for our improved algorithm using a reduction employing the Valiant-Vazirani affine hashing method, and also extend the result to polynomial systems over Fq improving on subsequent work by Chen, Gao and Yuan \citeChenGao2018. We also suggest a new approach for extracting the solution of the Boolean polynomial system via a generalization of the quantum coupon collector problem \cite{arunachalam2020QuantumCouponCollector}.

Authors: Dvoryantsev D. D. , Sargsyan A. S. , Anisimov A. V. , Lishevich I. V.
Published: July 2023

The method of manufacturing high-strength structural carbon fiber from toupreg based on PPS-214 grade polyphenylene sulfide (Fortron, Germany) and AS4 high-strength carbon fiber (Hexcel, USA) using a promising ATL-technology (Automated Tape Laying) with laser heating is considered. The technology was adapted for the material under study, laboratory models in the form of plates were made, physical and mechanical tests of laboratory samples were carried out. The quality of the binder distribution and the presence of defects were assessed by raster electron microscopy. The influence of the reinforcement, pressing and vacuum heat treatment schemes on improving the mechanical properties of the studied carbon fiber was investigated. It has been found that the samples subjected to vacuum heat treatment have higher mechanical properties due to an increase in the adhesion of the toupreg tapes to each other and the removal of discontinuities formed during the calculation. The value of the ultimate strength at interlayer shear of samples made using a parallel-diagonal scheme increases by 108%, at bending by 370% and by 65% at compression.

By processing the toupregs by the ATL with laser heating and subsequent thermal treatment of the products, it is possible to obtain high-strength structural materials with improved physical and mechanical properties, as well as high repeatability and equality of properties throughout the area of the products, even using complex reinforcement schemes.
On a mathematical model of the cooling and crystallization of metal drops during centrifugal granulation
Authors: Zharov M. V.
Published: July 2023

A mathematical model has been developed for the crystallization of aluminum alloy granules under cooling conditions in an aqueous and water-steam media. The practical significance of the mathematical model lies in predicting the average value of the dendritic parameter of the obtained granules depending on the granulation method, the characteristics of the granulation process and the size of the obtained granules. The average value of the dendritic parameter makes it possible to predict the fineness of the granule structure and, consequently, the mechanical properties of the granular material. The mathematical model makes it possible to determine the speed of a melt drop in an aqueous media and takes into account the presence of a steam jacket effect, i.e., a vapor layer that appears between a crystallizing drop and an aqueous media, which significantly reduces the intensity of heat removal and the rate of crystallization. The application of the mathematical model was tested on the obtaining of granules of high-alloyed aluminum alloys (alloys D1 and D16 of the Al–Cu–Mg system, alloys V95 and V96Ts of the Al–Zn–Mg–Cu system), made by centrifugal spraying of the melt from a perforated rotating crucible and drip method during cooling in an aqueous media. The cooling rate and the crystallization rate of the granules obtained in real experiments were determined by measuring the dendritic parameter of the material structure. The mathematical model showed a high convergence of the simulation results and of real experiments of aluminum alloy granulation.

Authors: Lima Francisco Renato
Published: July 2023

Neste estudo, aborda-se a questão da comunicação em contextos médicos, com a finalidade de situar, como o tema ‘poder ou assimetria na relação médico-pacientes’, vem sendo tratado na literatura, com base em algumas pesquisas no campo teórico e aplicado, como por exemplo, as realizadas por Martine (1989), Magalhães (2000), Albuquerque (2002), Zacariotti (2003), e van Dijk (2010). Consoante aos resultados das pesquisas desses autores, apresenta-se o posicionamento assumido por Lima (2016), no tratamento do tema ao discutir, em seu trabalho, como se dá a compreensão na comunicação entre médicos e pacientes. O autor, na breve exploração que faz desse aspecto dentro da discussão do tema, concorda com os demais autores, corroborando com a ideia de que essa relação não é apenas assimétrica,como pretende Caprara; Rodrigues (2004), mas há, bem marcada, a presença do uso do poder na linguagem durante a comunicação entre médicos e pacientes.

A temática  tem sido discutida desde meados dos anos 80 quando o conceito de alfabetização e alfabetismo passa a dividir espaço e a contrastar com o de letramento tanto nos saberes que circulavam no meio acadêmico, quanto no ensino de língua portuguesa, sobretudo, nos anos iniciais do ensino fundamental. A obra Letramentos, Mídias, Linguagem realiza uma discussão substancialmente fundamentada de todo o processo de mutação sócio histórica no que se refere a linguagem e as práticas sociais, demostrando que através da história, a imagem, o som e o texto vêm se adequando às culturas e às práticas dos sujeitos atendendo assim as demandas sociais.

Biopharmaceuticals, including therapeutic antibodies, are rapidly
growing products in the pharmaceutical market. Mammalian cells, such as
Chinese hamster ovary (CHO) cells, are widely used as production hosts
because recombinant antibodies require complex three-dimensional
structures modified with sugar chains. Recombinant protein production
using mammalian cells is generally performed in conjunction with cell
growth. In this study, we developed a technology that controls cell
growth and recombinant protein production to induce recombinant protein
production with arbitrary timing. Expression of green fluorescent
protein (GFP) gene and a single-chain antibody fused with the Fc-region
of the human IgG1 (scFv-Fc) gene can be induced and mediated by the
estrogen receptor-based artificial transcription factor Gal4-ERT2-VP16
and corresponding inducer drugs. We generated CHO cells using an
artificial gene expression system. The addition of various
concentrations of inducer drugs to the culture medium allowed control of
proliferation and transgene expression of the engineered CHO cells. Use
of 4-hydroxytamoxifen, an antagonist of estrogen, as an inducing agent
yielded high gene expression at a concentration more than 10-fold lower
than that of β-estradiol. When scFv-Fc was continuously produced under
inducing conditions, stable production was possible for more than 2
weeks while maintaining high specific productivity (57 pg
cell day). This artificial gene
expression control system that utilizes the estrogen response of
estrogen receptors can be an effective method for inducible production
of biopharmaceuticals.
Closed Inguinal Castration technique in horses compared with Field Castrations using post-operative Serum Amyloid A analysis.

Introduction: A closed inguinal castration technique was compared with
field castrations based on the post-operative (p.o.) inflammatory marker
Serum Amyloid A (SAA). Third day p.o. SAA, which has been related to
trauma, has been reported after field castrations in four different
studies in literature between 500 mg/l and 700 mg/l. These values were
compared with SAA values measured on day three after routine castration
using a closed inguinal approach applied under general anaesthesia under
strict aseptic conditions. Materials and Methods: 51 Male horses were
presented for routine castration. Serum was collected pre-operatively
and on day 3 post operatively. Castration was performed using a closed
inguinal approach in dorsal recumbence under general anaesthesia. The
vaginal process was retrieved by blunt dissection over an inguinal skin
incision. The closed proximal vaginal process was crushed by a Sand
emasculator and ligated at this site. Vaginal Process with content was
cut off 10 mm distal to the ligated site. Skin incisions were closed
intra cutaneously. Antibiotics or anti-inflammatory drugs were not
applied. Results: 48 horses tested negative (SAA< 3mg/l)
pre-operatively. Two ponies and one standardbred showed pre-operative
5mg/l, 7mg/l and 75mg/l respectively. Mean SAA value of all 51 horses,
three days post operatively, measured 94mg/l. 27 Horses showed no
elevation in SAA (<3mg/l). Only 8 horses showed SAA values
>100mg/l, of which 4 horses > 500mg/l,
(514mg/l, 747mg/l, 1110 mg/l and 1160 mg/l) possibly related to
additional trauma. Excluding these 4 cases results in a mean SAA value
of 27mg/l. Conclusion: Castrations, using a closed inguinal approach, in
which proper surgical standards can be maintained, proved to be far less
traumatic than field castrations.
A Small-Scale the Vertical Earth Heat Exchanger Geothermal Energy System
Authors: Rybach Ladislaous
Published: July 2023

The vertical earth heat exchanger (VHE) is a simple device providing a closed circuit for a fluid to take heat from the first tens/hundreds of meters of ground and to feed the cold side (evaporator) of a heat pump. Different types of VHE have evolved using coaxial tubes or U-tubes inserted into the ground in backfilled drill holes. Tube dimensions up to 10 cm diameter and probe lengths up to 100 m are the most common. Space heating and warm-water supply for a single-family dwelling with 12 KW capacity can be provided by two or three VHE's about 50 m in length. Long-term performance characteristics and the perturbations of the natural temperature field of VHE systems must be known for licensing decisions. Based on the results of field and theoretical studies, key performance parameters like fluid circulation velocity and ground thermal conductivity are identified and the necessary distance between VHE installations is discussed. It is concluded that VHE systems offer an interesting alternative energy source especially if coupled with a simple solar recharge unit.O trocador de calor vertical (VHE) é um dispositivo simples que estabelece um circuito fechado para que um fluido retire calor nas primeiras dezenas/centenas de metros de profundidade e alimente o lado frio (evaporador) de uma bomba de calor. Tipos diferentes de VHE foram desenvolvidos utilizando tubos coaxiais ou em forma de U, que são introduzidos em perfurações no terreno as quais são novamente preenchidas. Dimensões do tubo de até 10 cm de diâmetro e comprimento das sondas de até 100 m são as mais comuns. Calefação e fornecimento de água morna, para uma residência familiar com capacidade de 12 KW, podem ser atendidas com dois ou três trocadores de calor com cerca de 50 m de comprimento. As características de funcionamento a longo prazo e as perturbações do campo natural de temperatura dos sistemas de trocadores de calor, devem ser conhecidas para efeitos de licenciamento. Com base nos resultados dos estudos experimentais e teóricos são identificados neste trabalho, alguns parâmetros importantes, tais como velocidade de circulação dos fluidos e condutividade térmica do terreno. A distância necessária entre os trocadores de calor é discutida. Conclui-se que os sistemas VHE oferecem uma interessante fonte de energia alternativa especialmente se acoplados com uma unidade de recarga solar.

Published: July 2023

The first isotopic and geochemical data on samples of fresh waters, hot waters and vapor condensates from the geothermal system Copahue-Caviahue are presented. 3H, 2H and 18O analyses, suggest that the recharge of meteoric water in the deep seated reservoir occurs at around 2000 m a.s.l. In addition a shallower hot water reservoir shows a recent recharge at the same altitude. δ13C of the CO2 coming with vapor in one of the fumaroles ("Las Maquinitas") -6,80/oo vs PDB and the high gas-vapor ratio account for its magmatic origin and for the existence of a magmatic fed hydrothermally altered pipe. δ18O and δ2H data on vapor of the "Copahue-1", first drilled geothermal well, sampled recently and two years ago, show an evolution in the isotopic content as well as in the gas vapor ratio. This fact along with the geochemical and geophysical evidence allow the establishment of a preliminary model for the geothermal reservoir.
