Published: July 2023

Heat flow in the Medium Amazon Basin was determined using the thermal resistance method due to Bullard. The thermal conductivity of the lithological section of each well was determined by combining laboratory measurements of representative samples of the well column. Corrections due to porosity, fluid content and temperature have been applied to the measured thermal conductivity. The thermal gradients of the Basin vary from 8.3 to 47.0°C/km. The Basin is characterized by a mean gradient of 21.8°C/km, mean thermal conductivity of 4.72 mcal/cm s °C and a mean heat flow of 1.03 μcal/cm² s. The observed heat flow distribution of the Basin is caused by fluid motion through the main hydrological systems. This conclusion relies on hydrodynamic studies in the Basin, that allowed us to localize potentiometric lows and highs, defining in this way convergent fluid zones. The heat flow and thermal gradient maps, when integrated with the hydrodynamics sections, showed an excellent correlation between the heat flow distribution and the hydrodynamics of the Basin. O fluxo térmico da Bacia do Médio Amazonas foi determinado usando o método de resistência termal proposto por Bullard. A condutividade térmica da seção litológica de cada poço foi determinada combinando medidas de laboratório em amostras representativas da coluna do poço. Correções devido à porosidade, conteúdo de fluido e temperatura foram aplicadas à condutividade térmica medida. Os gradientes térmicos da bacia variam de 8.3 a 47.0°C/km. A bacia é caracterizada por um gradiente médio de 21.8°C/km, condutividade térmica de 4.72 mcal/cm s °C e um fluxo médio de 1.03 μcal/cm2 s. A distribuição de fluxo térmico observada na bacia é causada por movimento de fluido através dos principais sistemas hidrogeológicos. Esta conclusão fundamenta-se em estudos hidrogeológicos na bacia, os quais permitiram localizar baixos e altos potenciométricos, definindo desta forma zonas de fluido convergentes. Os mapas de fluxo térmico e gradiente térmico, quando integrados a seções hidrodinâmicas, mostram uma excelente correlação entre a distribuição de fluxo térmico e a hidrodinâmica da bacia.

Published: July 2023

Nowadays, denim is in trend. To achieve visually appealing results, various washing processes are applied to denim. For washing denim, a variety of methods are available, and they all produce distinct kinds of waste. These methods have various environmental effects. This study aims to examine the environmental impact of various denim washing effluents. Here, six different washes desizing, enzyme, stone, bleach, acid, and random wash are performed. In order to compare how washing affects both the environment and the fabric, effluent tests are carried out. Since enzymes are unique by nature, enzyme wash demonstrated the greatest GSM. They don't affect the fibre composition; they just break down the color that is on the surface of the cellulose. Shrinkage is the cause of the general rise in GSM. However, the thickness, pilling, and elongation % of the cloth were unaffected by the washing. Due to the alkaline nature of the washing procedure, which results in minimal harm to the cloth, the enzyme and desize wash exhibit high strength. The fabric's rigidity decreases when stone, bleach, and acid wash damage it, which raises the angle at which the crease recovers. Due to the use of enzyme and desize wash produces effluent with a reduced TDS. In these procedures, the indigo hue on the denim surface is diminished, which causes the fading to occur. This process results in less polluted water that is simpler for wastewater treatment plants to process.

Fine aggregate plays a key role as a filler material in concrete’s fresh and hardened properties. Generally, in Portland cement concrete aggregate occupies 70-85% by weight and 60-70% by mass. In Pakistan, Lawrence pur the sand as the only sand that meets the ASTM standards. But due to heavy transportation costs, it is not cost-effective to use in most parts of the country. The tests were carried out in accordance with ASTM standards, and the concrete mix designed with three water-cement ratios of 0.40,0.45, and 0.50 called for a mixing procedure. At 28 days of curing, an M30 concrete mix comprising five control mixes including parent concrete was evaluated and compared to parent concrete. This experimental work aimed to enhance the fresh and hardened properties of concrete such as the workability of concrete mix, compressive, and flexural strengths by using locally available Jhelum River sand gradation crushed sand (passing sieve #4, the waste product of Sargodha coarse aggregate), s a fine aggregate material. Using six sigma DMAIC Methodology 9 defects in the Jhelum River sand and control mix have been identified and corrective measures were taken to improve the quality of the concrete mix. The results derived from this experimental work show that adding 50% crushed sand in Jhelum River sand increases compressive strength by 27% and flexural strength by 20% which makes it according to ASTM Standards. The use of crushed sand as an alternative to natural river sand efficient and safe material. This control mix also reduces the construction cost by 10% in comparison to lawerancepur sand.

Published: July 2023

The most influential source of energy in our lives is solar energy. Solar energy reaches the earth in three different forms, i.e., Global, diffused, and Direct Solar Radiation. The Solar flux at the earth's surface depends on the intensity of these radiations and is a function of the values of latitude and longitude. The earth's temperature and hence dewpoint are greatly affected by solar flux. This idea is used for predicting solar radiation with input parameters, temperature, and dewpoint along with day number and month. The method of prediction of solar radiation used in the study is Artificial Neural Network (ANN). ANN has four variables in the input, ten neurons in the hidden layer, and three output parameters GSR. DSR and BSR. Six different types of errors, namely, Root Mean Square error (RMSE), Mean Absolute Error (MABE), Mean percent error (MAPE), Chi-square, Coefficient of Determination, Kolmogorov Smirnov, have been calculated for training, testing, and validation mode to check the accuracy of estimation. The values of all the errors are low, which indicates the prediction of solar radiation is reliable.

Published: July 2023

A new approach was developed to prepare NaZr2(PO4)3 (NZP) powders at low
temperature of 330?C. The effect of different molar ratios of ZrO(NO3)2 ?
xH2O to NaH2PO4 ? 2H2O on the synthesis of NZP powders was systematically
investigated by XRD, FE-SEM, TEM, EDS and Raman spectroscopy. The
mineralizer NaNO3 was formed in situ due to the mechanochemical reaction
between raw materials ZrO(NO3)2 ? xH2O and NaH2PO4 ? 2H2O during the
grinding process. When the optimal molar ratio of Zr:P = 2:6 was used, the
NZP powders with high crystallinity, good dispersity and particle sizes in
the range of 500-700 nm were obtained. The dense NZP ceramics was obtained
by sintering at 1100 ?C for 3 h with 2 wt.% ZnO as the sintering aid. The
relative density and Vickers hardness of the sintered ceramics reached 93.4%
and 704MPa, respectively.

Authors: Yasar Zeynep , DeLucca Vincent , Haber Richard
Published: July 2023

In this research, SiC ceramics were densified via spark plasma sintering
(SPS) with 0.5wt.% B4C and 1.5wt.% C additions at temperatures ranging from
1900 to 2000?C for 5-65min under 10-50MPa applied pressure with an
intermediate dwell at 1400?C, and the effects of applied pressure,
sintering temperature, and dwelling time were examined. The samples sintered
under 50MPa applied pressure had high density (>99%), and showed high
elastic modulus (~420MPa). However, lower applied pressure caused a decrease
in density and elastic properties. The increase of sintering temperature
from 1900 to 2000?C, while sintering time and pressure remained the same,
caused grains coarsening. Increasing the dwelling time for the samples
sintered at 1900 and 2000?C showed that sintering at a relatively lower
temperature for a longer period of time did not increase grain size
significantly. On the other hand, increasing the dwelling time at 2000?C
caused excessive grain growth. The results show that fine-grained highly
dense SiC can be produced by spark plasma sintering at 1900?C for 5min
under 50MPa.

Whole-body glucose homeostasis is coordinated through secretion of glucagon and insulin from pancreatic islets. When glucose is low, glucagon is released from α-cells to stimulate hepatic glucose production. However, the mechanisms that regulate glucagon secretion from pancreatic α-cells remain unclear. Here we show that in α-cells, the interaction between fatty acid oxidation and glucose metabolism controls glucagon secretion. The glucose-dependent inhibition of glucagon secretion relies on pyruvate dehydrogenase and carnitine palmitoyl transferase 1a activity and lowering of mitochondrial fatty acid oxidation by increases in glucose. This results in reduced intracellular ATP and leads to membrane repolarization and inhibition of glucagon secretion. These findings provide a new framework for the metabolic regulation of the α-cell, where regulation of fatty acid oxidation by glucose accounts for the stimulation and inhibition of glucagon secretion.

Article Highlights

It has become clear that dysregulation of glucagon secretion and α-cell function plays an important role in the development of diabetes, but we do not know how glucagon secretion is regulated. Here we asked whether glucose inhibits fatty acid oxidation in α-cells to regulate glucagon secretion. We found that fatty acid oxidation is required for the inhibitory effects of glucose on glucagon secretion through reductions in ATP. These findings provide a new framework for the regulation of glucagon secretion by glucose.

Immunomodulation combined with antigen therapy holds great promise to arrest autoimmune type 1 diabetes, but clinical translation is hampered by a lack of prognostic biomarkers. Low-dose anti-CD3 plus Lactococcus lactis (L. lactis) bacteria secreting proinsulin and IL-10 reversed new-onset disease in non-obese diabetic (NOD) mice, yet some mice were resistant to the therapy. Using microRNA (miRNA) profiling, six miRNAs (i.e., miR-34a-5p, miR-125a-3p, miR-193b-3p, miR-328, miR-365-3p, and miR-671-3p) were identified as differentially expressed in plasma of responder versus non-responder mice before study entry. After validation and stratification in an independent cohort, plasma miR-193b-3p and miR-365-3p combined with age and glycemic status at study entry had the best power to predict with high sensitivity and specificity poor response to the therapy. These miRNAs were highly abundant in pancreas infiltrating neutrophils and basophils with a pro-inflammatory and activated phenotype. Here, a set of miRNAs and disease-associated parameters are presented as predictive signature for the L. lactis-based immunotherapy outcome in new-onset type 1 diabetes, hence allowing targeted recruitment of future trial participants and accelerated trial execution.

Published: July 2023

While many individuals are able to achieve weight loss, maintaining this loss over time is challenging. We aimed to study whether genetic predisposition to general or abdominal obesity predicts weight re-gain after weight loss. We examined the associations between genetic risk scores for higher BMI and higher waist-hip ratio adjusted for BMI (WHRadjBMI) with changes in weight and waist circumference up to 3 years following one year of a weight loss program in participants (822 women, 593 men) from the Look AHEAD study who had lost ≥ 3% of their initial weight. Genetic predisposition to higher BMI or WHRadjBMI was not associated with weight regain after weight loss. However, the WHRadjBMI genetic score did predict an increase in waist circumference, independent of weight change. To conclude, a genetic predisposition to higher WHRadjBMI predicts an increase in abdominal obesity after weight loss, whereas genetic predisposition to higher BMI is not predictive of weight regain. These results suggest that genetic effects on abdominal obesity may be more pronounced than those on general obesity during weight regain.

Published: July 2023

Background and purpose: Most displaced distal radius fractures (DRF) are treated nonoperatively, with reduction and immobilization in a cast. Studies assessing intra- or inter-observer agreement on radiologic measurements of casting position have not been published, which was the aim of our study.Patients and methods: Our study is based on the Kuopio Osteoporosis Risk Factor and Prevention (OSTPRE) study. All detected DRFs during the OSTPRE follow-up were retrieved and based on sample size calculations 50 fractures were randomly selected for the study. 5 independent reviewers measured dislocation parameters and wrist position in a cast from the radiographs. A linear mixed model was used to estimate the concordance correlation coefficient (CCC) and total deviance index (TDI) that were used to evaluate intra- and inter-observer agreement. We used Kappa values to determine intra- and inter-rater agreement on radiographically acceptable reduction of the DRF. Limits of acceptable position were those defined by Finnish Current Care Guidelines.Results: For radial inclination, radial shortening, and dorsal/volar tilt, intra- and inter-observer correlations were high (CCC > 0.76). In addition, measurements of wrist angle in a splint had high correlations (CCC > 0.78), whereas measurement of intra-articular gap and step had poor correlations (CCC < 0.52). The Kappa value for overall agreement on the radiographically acceptable position of the DRF was modest (0.59).Conclusion: Intra- and inter-observer repeatability of casting position of radial inclination, radial shortening, and dorsal/volar tilt were high whereas intra-articular gap and step had poor correlations.

Published: July 2023

Regular weed surveys provide information on changes in weed communities. The composition of weed flora in spring cereal fields was investigated in southern and central Finland during 2020–2022. The survey was conducted in 16 regions, 226 farms and 549 fields. The occurrence of weeds was assessed in the second half of July from 90 organically cropped and 459 conventionally cropped fields. The weed flora was dominated by broad-leaved species, representing 81% of the total number of 138 identified species. The average species number per field was 21 in organic fields and 12 in conventional fields. The most frequent weed species in organic fields were Chenopodium album 99%, Erysimum cheiranthoides 84%, Viola arvensis 83% and Stellaria media 82%. In conventionally cropped fields, the most frequent species were Viola arvensis 83%, Stellaria media 65%, Galeopsis spp. 59% and Galium spurium 59%. The two most common grass species in both production systems were Poa annua and Elymus repens. The frequency and density of Poa annua had increased substantially in conventional cropping since the previous survey in 2007–2009. The average density of weeds was 384 plants m-2 in organic fields and 147 plants m-2 in sprayed conventional fields. The average air-dry biomass of weeds was 678 kg ha-1 and 151 kg ha-1, respectively. Elymus repens produced almost a quarter of the total weed biomass in both production systems. Changes in weed flora were minor in terms of frequency and density of the most common broad-leaved weed species. Increased infestation of Poa annua in conventional cropping calls for special attention. The dominance of Elymus repens decreased in both production systems since the previous survey.

Published: July 2023

Illicit brew consumption is a social challenge in most parts of the world today. Although illicit brew consumption results in psychological, social, physical and health problems, available studies have mostly linked the consumption of illicit brew to criminality in western countries with little evidence from the developing countries especially Kenya. The study sought to investigate the influence of illicit brews on security in Rongai Sub-County, Nakuru County Kenya, an area that has experienced an exponential rise of crime cases. The study had three objectives; to establish public perceptions on the influence of illicit brews on crimes causation, establish the influence of illicit brews use on public violence, and to determine the factors that impinge security management measures against illicit brews on security and safety in Kampi ya Moto in Rongai Sub-County. The study utilized a mixed methods research design. The census and purposive sampling techniques were used to draw a sample of 99 community policing committee members and 15 key informants for interviews respectively. The data collection methods were questionnaire and key informant interviews. Descriptive statistics and thematic analysis were used to analyse quantitative and qualitative data respectively. Statistical Package for Social Sciences was used to generate data analysis tools. The study established that Illicit brew consumption is associated with stealing household wares, property, phones and other items to obtain money to buy the liquor. The study also revealed that the common type of public violence caused by illicit brew consumption is fights in the public due to metal impairment as a result of illicit brew consumption. Lastly, the study established that general lethargy and corruption are the main factors impinge security management measures against illicit brews in the study area. The study concludes that illicit brew consumption is associated with crime since it is behind the stealing incidents. The study also concludes that illicit brew consumption in the study area is associated with fights in the public space due to mental judgement impairment to the extent that they fail to understand themselves and are involved in activities that amount to public violence. Lastly, the study concludes that general lethargy and corruption are the factors that impinge security Management measures against illicit brews. The study recommends economic empowerment programs by the government and other stakeholders in development to minimise poverty that drives some households to engage in making and selling illicit brew. The government should come up with strict regulations for law enforcement officers involved in corruption and support of illicit brew making and sale to help reduce the cases of illicit brew in the study area.

Published: July 2023

The class of materials known as carbon fibre or graphite reinforced polymers is one in which carbon fibre is most frequently employed to strengthen composite materials. The matrix for carbon fibres can also be made of non-polymer materials. Carbon has had very modest success in metal matrix composite applications because of the development of metal carbides and concerns about corrosion. In high-temperature applications, reinforced carbon-carbon (RCC), which is made of graphite reinforced with carbon fibres, is employed structurally.

 

The use of CFRP has grown since its inception because it provides classic metals like cast iron with considerably improved characteristics at a lower weight. Due to its unparalleled potential, this discovery has emerged as the new spearhead of material technology. In this study, the relationship between variations in the fibre mass and CFRP characteristics is examined. The test is conducted using ASTM standard test specimens and software from Ansys 2022 R1. Evaluating equivalent stress, strain, and total deformation of the composite under the same load is the main goal of this research.
Māori Sovereignty or Death
Authors: Rata Arama , Brayne Gabriella , Barber Simon
Published: July 2023

In her 1984 book ‘Māori Sovereignty’, Donna Awatere sustains a blistering polemic on ‘white culture’ that still retains its rhetorical force 40 years later. Her construction of a sharply delineated binary between a monolithic notion of ‘white culture’ as against ‘taha Māori’ can come at the cost of simplification. But this is not at all to say that Awatere is wrong when she says it is ‘Māori Sovereignty or death’. In this paper, we extend Awatere’s work by analysing relationships between colonialism and capital. We begin by situating Awatere’s work in its historical context, outlining major shifts in the global political economy, and drawing on Awatere’s analysis of Fascism to account for contemporary Far Right movements. Building from the inextricability of Fascism from the settler colonial/imperialist economy, we explore Awatere’s framing of whiteness as a system of racial exploitation and violence that enforces the state’s genocidal claims to sovereignty, defined through necropower – capitalism’s consumption of racialised death. We then consider the contradictions between capitalism and constitutional transformation. By scanning revolutionary movements elsewhere (in particular the Chilean movement for plurinationalism), we identify the need for extra-parliamentary, broad-based, popular power and constituent authority from below, as well as Indigenous solidarities and international alliances to circumvent anti-Māori populism and confront capital. In reflecting on the power of death, and the need for counter-hegemonic culture capable of securing the transition out of capitalism, we are drawn to the revolutionary essence of whakapapa as an Indigenous ontology that eternally resists necropower.
A cross-national study of internationalisation barriers with reference to SME value chain
Authors: Urban Wieslaw , Krot Katarzyna , Tomaszuk Anna
Published: July 2023

Research background: The study responses to the internationalisation issue, one of the essential factors of SMEs growth. Particularly to companies' efforts towards setting international cooperation and circumstances obstructing these struggles. The study takes into consideration that internationalisation in specific areas of company's operations differs noticeably. Similarly, different barriers may arise depending on the areas of the company's value chain that are the focus of the enterprises' internationalisation strategies.
Purpose of the article: This study aims to identify barriers to internationalisation regarding various areas of a company's value chain. The study employs the Value Chain Model by Porter.
Methods: The field data was collected using a questionnaire survey on a sample of small and medium enterprises (SMEs) located in countries in the Baltic Sea region (Denmark, Estonia, Finland, Germany, Latvia, Lithuania and Poland). A multiple regression analysis was performed to determine the impact of barriers on internationalisation.
Finding & value added: The study indicates three areas that are most often the subject of internationalisation in SMEs: operations, outbound logistics and marketing and sales. Barriers differ between value chain areas; however, cultural differences and competition are perceived as the most important hindering factors by companies experienced in internationalisation. At the same time, barriers regarding knowledge and finance diminish when companies becoming more experienced in internationalisation in particular value chain areas. This study is one of few employing the value chain framework to examine internationalisation.

Élete során minden harmadik ember megsérül közúti közlekedési balesetben. A baleseti veszteséget nem csak a család és a hozzátartozók szenvedik el, hanem nemzetgazdasági veszteséget is jelent egyben. A balesetek jelentős százalékában a járművezető és/vagy utas nem viselte a biztonsági övet, amellyel a baleset kimenetele és sérülés súlyossága szignifikánsan megnőhet.
Probability on Submetric Spaces
Authors: Jakubowski Adam
Published: July 2023

A submetric space is a topological space with continuous metrics, generating a metric topology weaker than the original one (e.g. a separable Hilbert space with the weak topology).

We demonstrate that on submetric spaces there exists a theory of convergence in probability, in law etc. equally effective as the Probability Theory on metric spaces. In the theory on submetric spaces the central role is played by a version of the Skorokhod almost sure representation, proved by the author some 25 years ago and in 2010 rediscovered by specialists in stochastic partial differential equations in the form of “stochastic compactness method”.

Currently, coccidiostats are the primary and standard method of combating coccidiosis in poultry farms. However, consumer organizations still point to the need to phase out all chemotherapeutic substances from animal nutrition to protect human health. The research material consisted of 720 cocks of the Cobb 500 hybrid, which were divided into three groups (C – coccidiostat/control, V – vaccine, and H – herbals). The following parameters were analyzed: body weight (BW), feed conversion ratio (FCR), mortality, foot pad dermatitis (FPD), European Production Efficiency Factor (EPEF), and the number of oocysts per 1g of feces (OPG). On day 42, the BW of the C group was higher compared with the V and H groups. The C group was also characterized by the best FCR and the highest EPEF. In the V group, oocysts were noted in feces from the 14th day of rearing, and the highest oocysts content was observed on the 21st day of life. In the C and H groups, the highest number of oocysts was recorded in the feces on the 28th day. The investigated alternative methods to coccidiostats showed good antiparasitic potential. Therefore, combining a couple of anticoccidiosis methods in preventive programs may be the best solution in broiler chickens production.

In a healthy physiological state, the mucous membrane of the oral cavity creates a suitable environment for the colonization of Candida spp. yeasts. The aim of the study was to analyze the nanomechanical properties of C. albicans cells derived from the oral cavity of healthy people in a biofilm produced in laboratory conditions. Candida spp. were sampled from the oral cavity of healthy individuals. The process of biofilm formation was analyzed using classic microscopic observation enriched with SEM (scanning electron microscope) and the nanomechanical properties of the cells were assessed with the use of the atomic force microscopy technique (AFM). From all isolated strains in the samples collected of the oral cavity healthy people was detected 79% C. albicans. Other isolated species belonged to the group „non-albicans”. The observations of C. albicans carried out in 24-h cultures revealed a tendency of the cells to form a biofilm structure with multilayer cell systems. The diameter of C. albicans cells in this structure was 5.75 µm, and the length of the pseudohyphae was 17.08 µm. The presence of an extracellular substance surrounding the C. albicans cells was detected. The mean value of the adhesion force determined for C. albicans cells was 4.01 nN. Areas with increased hardness (Force Modulation Mode signal; FMM signal) were found mainly in the zones of cells in contact with the glass substrate. The analysis of Candida cells in liquid samples gives satisfactory results, as it prevents unfavorable changes in the cell surface and thus provides more reliable results. The quality of the biofilm is probably related to the nanomechanical properties of C. albicans cells and may consequently contribute to the stability of the biofilm structures and their susceptibility or resistance to antifungal drugs.

The presence of Candida spp. especially in companion animals (dogs, cats) poses a risk of their transmission to the human organism. For this reason, it is advisable to undertake additional research to analyze the ability of zoonotic-origin Candida spp. to form biofilms with comparison of the biofilm-formation capacity of species isolated from humans.

Published: July 2023

Background

Stereotactic body radiation therapy (SBRT) precisely and non-invasively delivers ablative radiation dose to tumors in early-stage lung cancer patients who are not candidates for surgery or refuse it. The aim of research was to evaluate local control, overall survival (OS), local progression free survival (LPFS), distant metastases free survival (DMFS), disease free survival (DFS) and toxicity in early-stage lung cancer patients treated with SBRT in a single tertiary cancer centre.

Patients and methods

We retrospectively evaluated medical records and radiation treatment plan parameters of 228 tumors irradiated in 206 early-stage lung cancer patients between 2016 and 2021 at the Institute of Oncology Ljubljana.

Results

After 25 months of median follow up, 68 of 206 (33%) patients died. Median OS was 46 months (CI 36–56), 1-year, 2-year and 3-year OS were 87%, 74% and 62% and 5-year OS was 31%. A total of 45 disease progressions have been identified in 41 patients. Local progress only was noticed in 5 (2%) patients, systemic progress in 32 (16%) and combined systemic and local in 4 (2%) patients. Local control rate (LCR) at 1 year was 98%, at 2 and 3 years 96% and 95% at 5 years. The 1-, 2- and 3-year LPFS were 98%, 96% and 94%, respectively and 5-year LPFS was 82%. One, 2-, 3- and 5-year DFS were 89%, 81%, 72% and 49%, respectively. Among 28 toxicities recorded only one was Grade 4 (pneumonitis), all others were Grade 1 or 2. No differences in LCR, LPFS, DFS were found in univariate analysis comparing patient, tumor, and treatment characteristics. For OS the only statistically significant difference was found in patients with more than 3 comorbidities compared to those with less comorbidities.

Conclusions

Early lung cancer treated with SBRT at single tertiary cancer centre showed that LCR, LPFS, DFS, DMFS and OS were comparable to published studies. Patients with many comorbidities had significantly worse overall survival compared to those with less comorbidities. No other significant differences by patient, tumor, or treatment characteristics were found for DMFS, LPFS, and DFS. Toxicity data confirmed that treatment was well tolerated.
