One of the biotechnology reproductive used is estrus synchronization. This study determined the body’s physiological, estradiol level, and ovarian and follicle diameter in Peranakan Ongole (PO) cow estrus synchronization using modified progesterone-PGF2α and double injection of PGF2α. This study used 10 PO cows which were divided into two groups. Group 1, cows were given a modified intravaginal sponge containing 250 mg progesterone/sponge for 6 days, followed by intramuscularly injection of PGF2ɑ 25 mg/cow on day sixth. Appearance of estrus was observed on day 7th -9th. Group 2, cows were given a double injection 25 mg/cow of PGF2ɑ intramuscularly at 14-day intervals, then estrus was observed on day 15th -17th. The vaginal temperature was checked using a thermometer, the respiratory frequency was checked by inspection of thorax movements, and the pulse rate was checked by palpation of the coccygeal artery. Ovarian and Graafian follicle diameters were examined using ultrasonography. The data were analyzed using either T-Test or descriptive test. The results showed that in cows that were synchronized to estrus using combination of modified progesterone-PGF2ɑ and double injection of PGF2ɑ, the vaginal temperature, pulse rate, and respiration frequency were 36.9±0.98 and 37.34±0.83, 57.60±12.52 and 74.80±26.59, 30.40±10.43 and 20.00±2.83 respectively. There was no significant difference in ovarian and follicle diameter (P>0.05). The conclusion was the results of body physiology were in normal conditions but still below the average of cows undergoing estrus, and there were no significant differences in ovarian and Graafian follicle diameters.

Exploitation of powered roof support in variable mining and geological conditions
Authors: Borska Beata
Published: June 2023

The powered roof support is one of the essential elements of the technical equipment of the longwall. It is responsible for the safety of machines and workers. In addition, its function is to move the entire wall complex along the operational progress of the combine. Choosing the proper powered roof support per the conditions prevailing in the wall is an important factor for safe and effective operation. The aim of the study was to assess the mining and geological conditions in Polish hard coal mines in terms of the operation of powered roof support. The author focused mainly on analysing the risk of rock mass shocks, which significantly impact the work of the powered roof support. The work describes the development of the risk of tremors in recent years. The analysis showed an intense increase in this threat. We present an analysis of rock mass shocks registered in Polska Grupa Górnicza S.A. (Polish Mining Group), the main producer of hard coal in Europe. The results presented in this paper illustrate the scale of the risk of rock mass shocks. The current state of the tremor hazard presented in the paper may be helpful information in determining the directions of development and optimisation of the powered roof support.

Authors: Dabek Przemyslaw , Krot Pavlo , Wodecki Jacek , Zimroz Pawel , Szrek Jaroslaw , Zimroz Radoslaw
Published: June 2023

Monitoring and diagnostics of elements of the belt conveyor is a challenging task. One of the hardest aspects is dealing with objects such as rolling idlers that support the belt. They are distributed along the entire length of a conveyor, and their amount can easily reach thousands. In the ideal case, every idler should undergo in-situ monitoring, however, this is impractical. Hence, it is proposed to use remote sensing to acquire knowledge about some aspects of their condition. In particular, the authors propose to measure the rotational speed of the idler based on short video recordings. This data could be captured by mobile inspection robots, such as UAVs or UGVs, or even manually. Detecting the fact that the idler rotates with improper speed (lower than nominal), could indicate a developing fault of the internal bearing. An idler that rotates slower than it should also create additional friction between itself and the belt. This friction can increase the overall operational resistances, and even cause fire due to increased temperature. In this paper, the authors present a simple method for establishing the rotational speed of the idler based on video data analysis.
Robust switching Kalman filter for diagnostics of long-term condition monitoring data in the presence of non-Gaussian noise
Authors: Shiri Hamid , Wodecki Jacek , Zimroz Radosław
Published: June 2023

Machinery condition prognosis system uses long-term historical data to predict remaining useful life (RUL). One of the critical steps to reach this purpose is to segment long-term data into two or several degradation stages (Healthy, Unhealthy, and Critic stage). Finding changing points between regimes may be a crucial preliminary task for further predicting the degradation process. However, finding the accurate partition into two or more regimes is a challenging task in the actual application when the noise inherent in the observed process is non-Gaussian. Therefore, this paper introduced a robust methodology based on switching Kalman filters to address the problems mentioned. This approach uses multiple dynamic system models to explain different degradation stages, utilizing robust Bayesian estimation. Also, based on this fact, this approach works based on dynamic behavior; a threshold for diagnostics is no longer needed. Ultimately, the proposed approach is applied for the online diagnosis of simulated data sets in the presence of Gaussian and non-Gaussian noise. The result of the applied methodology on simulated data sets proves the method’s efficacy.

Published: June 2023

Underground mining of deposits is strongly dependent on several key processes enabling its safe operation. One of these processes is mine ventilation aimed at supplying an appropriate amount of air with a specific chemical composition, diluting harmful gases generated in technological processes and emitted from the rock mass, and ensuring appropriate climatic conditions at workplaces. For all that mine ventilation has strategic importance and is responsible for 30-40 % of overall mine operation costs. A very important task is to conduct calculations and simulations to determine the airflow in ventilation networks, both existing and planned in the future, along with the progress of the mine operation. In the era of the development of modern technologies, new perspectives for changing the current approach to the design and optimization of ventilation networks are available. Their utilization may contribute to accuracy improvement, which can drive safety increases and process optimization. In this article, the authors evaluate the possibilities of using laser scanning data, collected with LiDAR / Terrestrial Laser Scanner, to generate 3D models of underground structures geometry, and its further utilization to conduct numerical simulations of airflow in mining excavations with Computational Fluid Dynamics. The performed analysis shows that the proposed approach may be a useful instrument for analyzing local airflow phenomena, particularly in complex ventilation networks, where disturbances in air velocity vectors are caused by sudden changes in geometry.

Authors: Maciejewski P
Published: June 2023

According to the hypothesis of radiation hormesis, in appropriate doses, radon may have a positive effect on the human body, but it’s too high concentration becomes harmful. According to the applicable provisions of law, some employers are obliged to measure the concentration of radon activity in the air. The article presents the results of long-term measurements (with CR-39 detectors) and the results of short-term measurements made by the author (using the AlphaGuard device) in a public utility facility - a kindergarten in Bolesławów. It is located in an area with moderate radon potential. The article presents the results for two rooms. In one of them, construction works took place before the measurements, during which the floor was protected with a foil, on which a screed was made. In the second, this procedure is only planned. Based on the results, it was found that the floor insulation can reduce the concentration of radon activity in indoor air even three times. Short-term measurements also showed a significant influence of air exchange on the concentration of radon activity. Thanks to airing the room, the concentration of radon activity can be reduced two or even three times.

Vertical Extension of Soil Moisture Data in Hungarian Soil Types with Different Interpolation Methods
Authors: Deák T , Dobos E , Kovács Z K
Published: June 2023

An important step in today’s modern precision crop production systems is the development of an irrigation system for arable lands. Most of these systems only examine the top, 10 cm layer of the soil. The problem is that the root system of the crops also penetrates and grows into the deeper layers while absorbing water. For this reason, there is a need for a cost-effective solution to quantify the amount of water up to 1 meter depth. Sentek EnviroSCAN sensors were used to measure soil moisture (SM) values of different soil types located in Hungary having different soil mechanical and chemical attributes. SM values were only measured at certain depths. The missing depths are supplemented with estimated data done by interpolation. However, these estimations are not enough, as these sensors were located on different soil types, i.e. one kind of interpolation method may not be suitable to all sensors without significant statistical error.

Several soil moisture sensors were deployed. Each of them is placed on a specific soil type. The measured SM depth values were then used to produce estimated SM values lasting from 10 to 100 cm by using 8 types of interpolation methods. The interpolation was performed using a Python framework called Scipy. The final result of the research is the evaluation of the model performance of the soil moisture data estimated by 8 types of interpolation methods for different soil types in Hungary.
Drought and flood hazards management for agricultural water users in Central Java, Indonesia
Authors: Mawardhi AD , Linga SN
Published: June 2023

Central Java has a huge population and is the food production area for Indonesia. Due to its geographical complexity and the human factor, it is very vulnerable to drought and flood hazards. This study aimed to analyse drought and flood events in Central Java and their impact on economic, environmental, and social aspects, as well as to evaluate the multi-hazard management in Central Java related to agriculture. Drought and flood monitoring were conducted by SPI and SPEI. Those hazard forecasting were done by correlating the selected drought index to MEI. The drought vulnerability of five municipalities in Central Java was evaluated by DVI. Proposed mitigation strategies were offered after evaluating the results and current disaster management. This study showed that SPEI-3 was the best method to determine dry and wet periods in Central Java during 1980-2010, and its correlation to MEI was relatively higher than other indices (R2=0.3612). Karanganyar is the least vulnerable region to drought (DVI=0.36) and Rembang has the highest DVI (0.59). Since numerous stakeholders are responsible for managing water availability for different sectors, then proposed improvements for current agricultural mitigation strategies are focused on government, farmers, public water supplier, and coastal residents and their particular measures.
Analysing regional development in Indonesia based on GDP and cement consumption from 2010 to 2020
Authors: Siringo R , Suwardi E , Haryono E , Kurniawan A
Published: June 2023

This article analyses regional development in Indonesia from 2010-2020, based on its cement consumption. It investigates the relationship between cement demand, GDP, population, and urbanization by using Ordinary Least Square regression. In this period, Java known as the central cement producer and intake most of the product from the market. However, cement consumption per capita (CCP) in Kalimantan was the highest during 2010-2015 and in Sulawesi during 2016-2020. Meanwhile, high distribution cost has caused Eastern Indonesia consumed cement the least. The regression analysis shows that nationally and in four regions, variables GDP and population have positively influence while urbanization has negative influence on the cement demand. This relationship, however, do not exist in Sulawesi and Maluku-Papua. Negative coefficient values of urbanization indicate that road transport infrastructures and public facilities has played a more important role in urban cement consumption rather than public housing. Secondly, we found that GDP per capita (GDPP) positively affect the CCP, unless in Kalimantan region. An increase of 1% GDPP will cause national CCP to raise by 0.005%, regional CCP in Java and Sumatra by 0.005% as well, but in Sulawesi, Bali-Nusa Tenggara, and Maluku-Papua, CCP will raise by 0.01%. The extreme CCP gap portrayed the disproportionate in regional development in the country. Although massive infrastructure projects have lessened the gap, it is necessary to have an adequate supply of the product in each region with affordable price to accelerate regional development.

The texts analyzed in this study are the articles in the local portal of “Nggalek.co,” which is locally produced by young people in Trenggalek. As the unit of analysis, there are 6 articles, selected by using the keyword of “tambang emas” (gold mining). This study aims at understanding the discursive strategy of the writers (Trenggalek community) in producing the text in building resistance discourse of the gold mining industry for ensuring the local sustainable development. This research is based on Foucauldian critical framework and critical discourse analysis by employing the Fairclough’s framework of three levels of analysis: micro, meso, and macro. The analysis resulted in identifying the discursive strategies in the form of key themes (knowledge produced) through the text, explaining the social political context of the resistance discourse, and identifying the power relations among the actors.
Komering wathersed land conservation under The Marga System
Authors: Istianda Meita , Irwanto Dedi , Giyanto
Published: June 2023

In the 1980s, efforts to integrate regions across Indonesia, especially South Sumatra, led to the elimination of customary law and customary government. Before the introduction of the Undang-Undang Desa (Village Government Law), South Sumatra’s customary government had adopted a customary government system known as the Marga system. This study employs a spatial methodology, combining historical maps and satellite pictures as data sources, to examine the level of deforestation in the Komering watershed from before the Marga government was dissolved till after it was abolished. In addition, the purpose of this study is to determine the function of customary law in preserving environmental sustainability in the Komering watershed. The results of processing the topographic map from 1910 were then compared to the results of processing the Sentinel-2 satellite image to see how the level of the land had changed over a century. The annual average rate of deforestation is around 274,944 ha per year. That is, there have been significant changes in land usage for 109 years. Part of the forest is converted into fields and plantations, while the majority of the swamps and marshes are converted into rice fields. The impetus for this transformation began in 1983, when the Marga government system was abolished. Long in charge of South Sumatra, the Marga Government System has already established regulations for conserving its natural resources. The system is a successful method for managing watersheds because of its pattern of limited land cover on slopes and along rivers. The inhabitants of South Sumatra are ruled by a system of Marga, and their daily lives are guided by the customary law. The Simbur Cahaya Customary Law controls sociopolitical connections between communities. The management of these relationships appears to be an effort to safeguard shared resources, such as forest timber plants and riverbank land. Consequently, customary law plays a vital role in protecting the environment, especially forest land and njurung land (mid-channel bar).

Local wisdom cannot be denied being able to maintain the environmental sustainability of indigenous peoples in various dimensions of life. The Samin community is one of the tribes in Indonesia that has a strong traditional spirit. The aim of the study is to describe local wisdom in the agricultural activities of the Samin community in Sambongrejo, Blora, Indonesia. A qualitative approach was developed to obtain a model of local wisdom in the ancestral teachings of the Samin community which are still being maintained. Collecting data in this study employed observation, interviews, documentation, and FGD (Focused Group Discussion) with several Indigenous Samin’s figures. The result shown teachings of Samin’s ancestors taught that life must be in harmony with nature. Therefore, agriculture is performed with the principle of zero waste to minimize environmental impact. The Samin community implements an integrated organic farming system with livestock so that the biological cycle can occur. Plants are cultivated by intercropping method for commodity diversity. Local wisdom that developed according to technological developments even though it is based on the old teachings (ancestors) can still provide maximum benefits for the sustainability of life. The zero-waste principle implemented to the Samin community’s agriculture is a manifestation of environmental ethics from the teachings of the ancestors to produce sustainable agriculture.

Authors: Kartika Fitria Dewi , Wijayanti Pipit
Published: June 2023

A prolonged absence of rainfall that results in a temporary reduction or deficit in the amount of natural water available is known as drought. The goal of this article is to examine how drought indices from various nations might be used to simulate the features of drought. Understanding the various drought indexes, as well as their benefits and drawbacks, is crucial. The literature review methodology is employed in this investigation. The Standardized Precipitation Index, or SPI, is the output of the most used modeling technique. Because this technique solely uses the rainfall series, it was discovered that about 57% of the articles utilizing the SPI drought index used the SPI index. The Palmer Drought Severity Index (PDSI), Standardized Precipitation Index (SPI), Standardized Runoff Index (SRI), Standardized Streamflow Index (SSI), and Standardized Precipitation Evapotranspiration Index were used to find additional articles, nevertheless (SPEI). According to several studies, the study methodology often compares drought index approaches using hydrological and meteorological data. It is envisaged that this approach might be applied in other nations to see a place from multiple angles with regard to its hydrology and meteorology.

Published: June 2023

Organic sodium-ion batteries (OSIBs) using eco-friendly organic materials as electrodes have recently received much attention. However, the practical applications of OSIBs are generally limited by the inherent disadvantages of organic electrodes, such as their low conductivity, poor stability, and high solubility in electrolytes. Herein, we presented [5, 10, 15, 20-tetrathienylporphinato] M (II) (MTTP, M=2H, Ni) as new electrode materials in sodium-organic batteries. The incorporation of thiophene functionalized groups and nickel (Ⅱ) ion in the molecular design of porphyrins enabled stable and excellent electrochemical performance in sodium storage systems. Benefiting from multiple charge storage sites and bipolar characteristics, the NiTTP anode has a reversible capacity of 434 mAh g−1 at a current density of 25 mA g−1. An excellent long-term cycling stability and high average voltage were obtained when NiTTP was used as a cathode. In a symmetrical battery, where NiTTP was used as both cathode and anode materials, a high average voltage of 2.3 V and a practical energy density of 93 Wh kg−1 was achieved. These results suggest that the thiophene-based porphyrin derivatives would be promising electrode materials for long-term organic sodium ion batteries for green and stable energy storage.
Dicodon-based measures for modeling gene expression
Authors: Alonso Andres M , Diambra Luis
Published: June 2023

Motivation

Codon usage preference patterns have been associated with modulation of translation efficiency, protein folding, and mRNA decay. However, new studies support that codon pair usage has also a remarkable effect at the gene expression level. Here, we expand the concept of CAI to answer if codon pair usage patterns can be understood in terms of codon usage bias, or if they offer new information regarding coding translation efficiency.

Results

Through the implementation of a weighting strategy to consider the dicodon contributions, we observe that the dicodon-based measure has greater correlations with gene expression level than CAI. Interestingly, we have noted that dicodons associated with a low value of adaptiveness are related to dicodons which mediate strong translational inhibition in yeast. We have also noticed that some codon-pairs have a smaller dicodon contribution than estimated by the product of the respective codon contributions.

Background

Immediate breast reconstruction after mastectomy can improve the quality of life for women with breast cancer and rates are increasing. Long-term inpatient costs of care were estimated to understand the impact of different immediate breast reconstruction procedures on healthcare expenditure.

Methods

Hospital Episode Statistics Admitted Patient Care data were used to identify women undergoing unilateral mastectomy and immediate breast reconstruction in English National Health Service hospitals (1 April 2009 to 31 March 2015) and any subsequent procedures performed to revise, replace, or complete the breast reconstruction. Costs were assigned to Hospital Episode Statistics Admitted Patient Care data using the Healthcare Resource Group 2020/21 National Costs Grouper. Generalized linear models were used to estimate mean cumulative costs for five immediate breast reconstruction procedures over 3 and 8 years, adjusting for covariates (age/ethnicity/deprivation).

Results

A total of 16 890 women underwent mastectomy and immediate breast reconstruction: implant (5192; 30.7 per cent), expander (2826; 16.7 per cent), autologous latissimus dorsi flap (2372; 14.0 per cent), latissimus dorsi flap with expander/implant (3109; 18.4 per cent), and abdominal free-flap reconstruction (3391; 20.1 per cent). The mean (95 per cent c.i.) cumulative cost was lowest for latissimus dorsi flap with expander/implant reconstruction (€20 103 (€19 582 to €20 625)) over 3 years and highest for abdominal free-flap reconstruction (€27 560 (€27 037 to €28 083)). Over 8 years, expander (€29 140 (€27 659 to €30 621)) and latissimus dorsi flap with expander/implant (€29 312 (€27 622 to €31 003)) reconstructions were the least expensive, while abdominal free-flap reconstruction (€34 536 (€32 958 to €36 113)) remained the most expensive, despite having lower costs for revisions and secondary reconstructions. This was driven primarily by the cost of the index procedure (€5435 (expander reconstruction) to €15 106 (abdominal free-flap reconstruction)).

Conclusion

Hospital Episode Statistics Admitted Patient Care Healthcare Resource Group data provided a comprehensive longitudinal cost assessment of secondary care. Although abdominal free-flap reconstruction was the most expensive option, higher costs of the index procedure need to be balanced against ongoing long-term costs of revisions/secondary reconstructions, which are higher after implant-based procedures.

Background

Epidemiological studies on acute aortic syndrome (AAS) have relied largely on unverified administrative coding, leading to wide-ranging estimates of incidence. This study aimed to evaluate the incidence, management, and outcomes of AAS in Aotearoa New Zealand.

Methods

This was a national population-based retrospective study of patients presenting with an index admission of AAS from 2010 to 2020. Cases from the Ministry of Health National Minimum Dataset, National Mortality Collection, and the Australasian Vascular Audit were cross-verified with hospital notes. Poisson regression adjusted for sex and age was used to investigate trends over time.

Results

During the study interval, 1295 patients presented to hospital with confirmed AAS, including 790 with type A (61.0 per cent) and 505 with type B (39.0 per cent) AAS. A total of 290 patients died out of hospital between 2010 and 2018. The overall incidence of aortic dissection including out-of-hospital cases was 3.13 (95 per cent c.i. 2.96 to 3.30) per 100 000 person-years, and this increased by an average of 3 (95 per cent c.i. 1 to 6) per cent per year after adjustment for age and sex adjustment on Poisson regression, driven by increasing type A cases. Age-standardized rates of disease were higher in men, and in Māori and Pacific populations. The management strategies used, and 30-day mortality rates among patients with type A (31.9 per cent) and B (9.7 per cent) disease have remained constant over time.

Conclusion

Mortality after AAS remains high despite advances over the past decade. The disease incidence and burden are likely to continue to increase with an ageing population. There is impetus now for further work on disease prevention and the reduction of ethnic disparities.

Objective

This study aims to evaluate the neonatal screening for congenital hypothyroidism (CH) and the diagnosis CH in the national health registers and to study the effects of lowering screening thyroid-stimulating hormone (TSH) threshold on the incidence of CH and birth characteristics of screening positive and negative CH children.

Design

This is a nationwide register-study of all children (n = 3 427 240) in the Swedish Medical Birth Register (MBR) and national cohort for screening positive infants (n = 1577) in 1980-2013.

Methods

The study population was further linked to several other Swedish health registers. Evaluation of the CH screening and CH diagnosis was performed with levothyroxine use in the first year of life as reference. The incidence of CH was estimated by the Clopper–Pearson method. Regression models were used to study associations between CH and birth characteristics.

Results

The neonatal CH screening had high efficacy, but 50% of all children with a CH diagnosis were screening negative. The incidence of screening positive CH increased (1/3375 to 1/2222), and the incidence of screening negative CH decreased (1/2563 to 1/7841) after lowering the TSH screening threshold in 2009. Screening negative CH was associated with female sex, twinning, prematurity, low birth weight, birth defects, and need of neonatal intensive care, and 42% had transient disease.

Conclusions

Despite high efficacy of the CH screening, 50% of children diagnosed as CH was screening negative. Although other factors influencing the incidence of the CH diagnosis cannot be ruled out, the incidence of screening negative CH decreased with lowering of the TSH threshold. Birth characteristics differed between screening positive and negative CH.
How women’s employment instability affects birth transitions: the moderating role of family policies in 27 European countries
Authors: Hsu Chen-Hao
Published: June 2023

Why women in some countries are more likely than others to postpone childbirth when facing employment instability? This study uses 2010–2019 EU-SILC panel data to explore whether the impacts of women’s employment instability, including being unemployed or temporarily employed by fixed-term contracts, on the first- and second-birth transitions differ across 27 European countries and how governments’ provisions of different family policies moderate such relationships. Results showed that while unemployment and temporary employment could generally delay women’s first- and second-birth transition, such effects varied across European countries and depended on the levels of family policy provisions. Countries with more generous family cash benefits were associated with less negative and even positive effects of women’s employment instability on birth transitions. On the other hand, the birth effects of women’s employment instability did not vary significantly across countries according to the length of paid maternity/parental leaves. Most strikingly, countries with higher childcare coverage rates were associated with more negative effects of women’s employment instability on birth transitions. These findings highlight the importance of family policy contexts in shaping women’s childbirth responses to unstable employment circumstances.

Current rising temperatures are threatening biodiversity. It is therefore crucial to understand how climate change impacts male and female fertility and whether evolutionary responses can help in coping with heat stress. We use experimental evolution to study male and female fertility during the real-time evolution of two historically differentiated populations of Drosophila subobscura under different thermal selection regimes for 23 generations. We aim to (a) tease apart sex-specific differences in fertility after exposure to warming conditions during development, (b) test whether thermal selection can enhance fertility under thermal stress, and (c) address the role of historically distinct genetic backgrounds. Contrary to expectations, heat stress during development had a higher negative impact on female fertility than on male fertility. We did not find clear evidence for enhanced fertility in males or females evolving under warming conditions. Population history had a clear impact on fertility response under thermal stress, particularly in males with those from lower latitude presenting better performance than their higher latitude counterparts. We show that the impact of thermal stress on fertility varies between traits, sexes, and genetic backgrounds. Incorporating these several levels of variation is crucial for a deeper understanding of how fertility evolves under climate change.
