Published: August 2024

The article discusses many external harvesting factors and adjustable parameters of the working parts of the TORUM combine harvester. A description is given of the technologies used to develop a program - a highly specialized database management system (DMS) - for information support of the process of adjusting a combine harvester, namely the system programming language Rust and modern web technologies for creating desktop applications with a graphical user interface. A hint system is described to improve the user experience for interacting with domain data. The “Settings” subsystem, used for preliminary configuration of combine harvesters, is examined in detail, and the Entity relationship is shown - a diagram of the database tables related to this subsystem. The software allows you to work with the database in two operating modes: in user mode for viewing the knowledge of interest in the subject area and in expert mode for editing, adding and deleting this knowledge. The implementation of the software system under consideration (expert system) can reduce time and improve the quality of decisions made and, as a result, will increase the shift productivity of combine harvesters.

Authors: Mkrtchyan G. V. , Boyko M. D.
Published: August 2024

The article presents the reproductive quality indicators of the Holstein herd of APA (C) “Kuzminsky” (Moscow region) with different milk productivity levels. Some patterns have been identified for the herd, reflecting associations between reproductive and productive traits. The coefficient of the reproductive capacity ranges in the herd from 0.976 to 0.986, and the highest average rate was noted among cows with the highest milk yields in the herd. It’s noteworthy that the largest group (n=100) with an average level of milk yield per herd was characterized by the lowest coefficient. The average calving interval is 372 days, which can be explained by an extended service period; the dry period duration in cows with high milk yields is the maximum among the studied livestock.

The results of a study of the development of the root system of Picea abies under growing conditions in the North of Russia (subzone of mid-taiga forests) are presented. A separate tree aged 34 years and 17 m high was selected for the study. The root system was exhumed with a 4x4 m square with a trunk in the center. For 3D modeling, a 360° scan was carried out on three sides of the root system using an Artec Evo handheld 3D scanner. As a result of the scanning, a 3D model of the root system was obtained with 251 individual roots with a diameter of 0.5 cm or more. Analysis of the 3D model showed that the total length of the root system was 18408 cm, and the average length of one root was 74.5 cm. The diameters of the roots varied from 0.5 to 18 cm, but 1–3 cm prevailed. The morphometric structure of the root system included four main large roots with with diameters of 14–22 cm, emanating from the tree trunk and directed perpendicular to each other, to which the roots of the conditional 2nd and 3rd orders were adjacent. Areas of increased growth of roots of different orders were identified in the diagonal direction. In general, the results obtained correspond to the ideas about the root architectonics of this type of tree.

Gauge theories are powerful theoretical physics tools that allow complex phenomena to be reduced to simple principles and are used in both high-energy and condensed matter physics. In the latter context, gauge theories are becoming increasingly popular for capturing the intricate spin correlations in spin liquids, exotic states of matter in which the dynamics of quantum spins never ceases, even at absolute zero temperature. We consider a spin system on a three-dimensional pyrochlore lattice where emergent gauge fields not only describe the spin liquid behavior at zero temperature but crucially determine the system’s temperature evolution, with distinct gauge fields giving rise to different spin liquid phases in separate temperature regimes. Focusing first on classical spins, in an intermediate temperature regime, the system shows an unusual coexistence of emergent vector and tensor gauge fields where the former is known from classical spin ice systems while the latter has been associated with fractonic quasiparticles, a peculiar type of excitation with restricted mobility. Upon cooling, the system transitions into a low-temperature phase where an entropic selection mechanism depopulates the degrees of freedom associated with the tensor gauge field, rendering the system spin-ice-like. We further provide numerical evidence that in the corresponding quantum model, a spin liquid with coexisting vector and tensor gauge fields has a finite window of stability in the parameter space of spin interactions down to zero temperature. Finally, we discuss the relevance of our findings for non-Kramers magnetic pyrochlore materials.
A quantitative model of temperature-dependent diapause progression
Authors: von Schmalensee Loke , Süess Philip , Roberts Kevin T. , Gotthard Karl , Lehmann Philipp
Published: August 2024

Winter diapause in insects is commonly terminated through cold exposure, which, like vernalization in plants, prevents development before spring arrives. Currently, quantitative understanding of the temperature dependence of diapause termination is limited, likely because diapause phenotypes are generally cryptic to human eyes. We introduce a methodology to tackle this challenge. By consecutively moving butterfly pupae of the species
Pieris napi
from several different cold conditions to 20 °C, we show that diapause termination proceeds as a temperature-dependent rate process, with maximal rates at relatively cold temperatures and low rates at warm and extremely cold temperatures. Further, we show that the resulting thermal reaction norm can predict
P. napi
diapause termination timing under variable temperatures. Last, we show that once diapause is terminated in
P. napi
, subsequent development follows a typical thermal performance curve, with a maximal development rate at around 31 °C and a minimum at around 2 °C. The sequence of these thermally distinct processes (diapause termination and postdiapause development) facilitates synchronous spring eclosion in nature; cold microclimates where diapause progresses quickly do not promote fast postdiapause development, allowing individuals in warmer winter microclimates to catch up, and vice versa. The unveiling of diapause termination as one temperature-dependent rate process among others promotes a parsimonious, quantitative, and predictive model, wherein winter diapause functions both as an adaptation against premature development during fall and winter and for synchrony in spring.

In 2005 and 2007, prompted by Nipah and avian influenza outbreaks, respectively, faculties at Chattogram Veterinary and Animal Sciences University (CVASU) in Bangladesh initiated a civil society network of researchers in animal and human health. This network led to the launch a year later of One Health Bangladesh (OHB), a platform with membership open to multi-disciplinary scientists, practitioners, and activists. Along with continued advocacy to advance One Health agenda, OHB partnered with government, UN agencies, and other stakeholders to develop, in 2012, a National One Health Strategic Framework and Action Plan. The National Plan was later endorsed by the Ministry of Health and Family Welfare (MoHFW), Ministry of Fisheries and Livestock (MoFL), and Ministry of Environment, Forest, and Climate Change (MoEFC) followed by its implementation which introduced a three-tier multi-sectoral coordination mechanism including the establishment of a One Heath Secretariat in 2016. In 2017, an operational budget for the One Health Secretariat (OHS) was allocated by the MoHFW and three mid-level government officers from three government agencies, and the Directorate General of Health Services (DGHS), Department of Livestock Services (DLS), and Bangladesh Forest Department (BFD) were seconded to the OHS to make the Secretariat functional. OHB and the OHS now work together to advance the institutionalization process and implement One Health activities including One Health capacity building, joint surveillance, outbreak investigation and intervention, advocacy in the form of arranging dialogs, seminars, workshops, and conferences, and promoting cross sectoral and transdisciplinary collaboration, networking, and partnership nationally and internationally.

Authors: Thanh Hai Le , Trung Kien Tran , Thanh Hung Nguyen
Published: August 2024

Earthworm organic waste is processed into vermicompost, which is of varying quality depending on the substrate. In vermicomposting, earthworms can promote nitrogen mineralization and effect nitrification. A challenging-to-absorb nutrient will be converted into a nutrient that plants can easily absorb to improve nutrients in soil and increase crop production. In this study, an experimental model of organic fertilizer production from catfish pond bottom sludge was implemented. Sludge from the bottom of catfish ponds is composted with water hyacinth in aquatic ponds to produce organic fertilizer, mature fertilizer is used as a substrate for vermicomposting. The impact of vermicompost on plant growth parameters was evaluated through its use to improve nutrients in soil. Sludge, compost, vermicompost, and soil quality were also evaluated for their physical and chemical properties. Results show that the growth coefficient of earthworms is 129.3±1.15% per 30 days, and the average amount of organic fertilizer created is 126±3.51 kg per 30 days. The quality parameters of vermicompost all meet national standards for organic fertilizer quality. The moisture and total organic matter content in mature fertilizer are 31% and 21.9%, respectively. The content of nutrients N and P increased compared to input materials, the corresponding values reached 2.84% and 0.96%. The C/N ratio is 7.7, microbiological and heavy metal indicators are within the accepted limits. In the experiment using vermicompost to cultivate Brassica rapa chinensis, the yield growth rate was the highest. After 21 days of planting, the growth rate is fast and the height reaches 25.0±0.38 cm. The biochemical composition ensures safety according to food regulations for leafy vegetables. Vermicomposting is recommended as a sustainable and suitable technique for catfish pond sludge utilizing.

Published: August 2024

Porous geopolymer materials have been recently used in environmental remediation applications as adsorbents. This study is to investigate the NH4
+ adsorption capacity of geopolymer activated from coal fly ash mixing with NaOH, Na2SiO3, and H2O2. The H2O2 with various ratios (0%, 4.5%, and 8.5%) were added into the fly ash pastes as blowing agents. The NH4
+ adsorption capacity of these materials was examined concerning the effects of NaOH concentration, H2O2 contents, adsorbent particle sizes, dosages, and NH4
+ concentration by batch adsorption test. The results show that adding 4.5% (G45) and 8.5% (G85) of H2O2 developed porous structures in geopolymer granules and their NH4
+ adsorption capacity depends on their particle sizes and pore structures. In particular, geopolymer granules with 8.5% H2O2 exhibited higher NH4
+ adsorption capacity than lower content of H2O2 in case of particle size of 3.0-8.0 mm. However, pulverized geopolymer still demonstrated the greatest NH4
+ adsorption capacity. In addition, both granules G45 and G85 demonstrated a well-fit (R2 = 0.97-0.99) with Langmuir and Freundlich isotherms. The maximum NH4
+ adsorption capacity of G85 was 19.86 mg/g, which indicated the NH4
+ adsorption potential of porous geopolymer granules generated from waste materials such as coal fly ash.

Published: August 2024

The indicator–based vulnerability assessment of households to typhoons and inundation was conducted in a ward of Da Nang city after the historical typhoon Son Ca 2022. A set of 18 indicators, encompassing three components of exposure, sensitivity, and adaptive capacity, was used for vulnerability assessment. In–depth and semi–structured interviews revealed that 42% and 89% of the interviewed households were affected by typhoons and inundation, respectively. The study noted that nearly 87% of households experienced inundation–induced damage at varying intensities in October 2022. The surveyed results also demonstrated that 88% of the interviewed households had at least 01 child under 11 years old, 22% had at 1–2 elderly above 65 years old in the family, and 16% were categorized as poor or near–poor households. 73% of the households resided in single–story houses (Type IV), 5% were living in temporary accommodations, and 8% lacked a stable livelihood. Although a high percentage of households were equipped with basic disaster mitigation tools (100%) and respondents received warning information about inundation (85%), only 16% engaged in disaster prevention training and propaganda courses. The assessment of exposure, sensitivity, and adaptive capacity to typhoons and inundation was 0.58, 0.39, and 0.34, respectively (0 to 1 scale). Although the survey area was considered a highly adaptable and proactive area to disasters, the present study revealed that the vulnerability to historical disasters in the survey area was 0.63 (–1 to 2 scale). The results indicate that residents and authorities are insufficiently prepared to manage historical disasters effectively. The results of this study offer valuable insights for policymakers and stakeholders in improving adaptive capacity and disaster preparedness effectiveness.

This will keep them unemployed. In other word client also face same problem, they can’t find labors according to their requirements. To bridge this gap and to develop better connection between client and labor we need a platform. Our idea is to develop a mobile application which includes data of construction labor such as his/her name, skills, and phone number. By surveying, collecting labor data and later by compiling it as a database we build a mobile application which will directly affect in improvement of construction labor status in and around Udupi region. Survey-based data in the selection process. Data collected at these hotspots would be categorized into geographical coverage, age, experience, and type of work. These statistics arrived from the raw data collected verbally from labors across these hotspots will be compiled and analysed to give us current availability of labors.

Durability Studies and Stress Strain Characteristics of hooked end steel fiber reinforced ambient cured geopolymer concrete
Authors: Laxmi G , Patil S G
Published: August 2024

For conventional concrete, the use of fibers has proven to improve the strength properties of the material. However, in the case of ambient cured geopolymer concrete, there are limited studies that explore the application of fibers, in particular, the use of hooked end steel fibers. Further, it is important to study the durability properties of geopolymer concrete with fibers, since it will influence the service life of the structures in practice. Therefore, in the present study, fiber-reinforced geopolymer concrete was synthesized using fly ash, GGBS, hooked end steel fibers, and alkaline solution made with Na2SiO3 and NaOH. The percentage of steel fibers varied in the range of 0.5% to 2% with an increment of 0.5% by volume fraction of the binder. The precursor materials were characterized using techniques such as X-ray fluorescence (XRF), X-ray diffraction (XRD), and scanning electron microscope (SEM). Durability studies like water absorption, drying shrinkage, sulphate attack were studied. In addition, the elastic constants were determined through stress strain behaviour of geopolymer concrete in uniaxial compression. The results of the experimental study showed that the addition of hooked end steel fibers influences the strength of geopolymer concrete up to an optimal percentage, which was found to be 1%. Furthermore, in terms of durability properties, the addition of fibers exhibited better results in terms of resistance to water absorption and chemical attack, and this was validated by the microstructural studies, where the specimens with hooked end steel fibers revealed much denser hardened geopolymer matrix when compared to the mixes without fibers.
Performance Study on Laterite Block with Perlite

The term “perlite” refers to an amorphous volcanic silicate/alumina rock that can expand at temperatures between 900 and 1200 ∼C when heated fast. Because perlite is so versatile, it can be applied in a variety of sectors, including construction, horticulture, petrochemical, and industrial. An item that is used in the construction sector is expanded perlite (EP). It can be used as an input for geopolymers or mixed with aggregate or cement to create conventional cementitious materials. EP offers low density, effective thermal and acoustic insulation, and exceptional fire resistance for buildings. Perlite appears to be a necessary material as a result. The author of this article examines the effects of EP, a chemical used in building materials, on the properties of geopolymers, different types of binder, and regular cementitious materials, both in their fresh and hardened states.

The usefulness of using perlite-reinforced laterite blocks as a sustainable building material is investigated in this work. We investigate this composite’s potential for usage in building applications by thoroughly examining its mechanical and thermal properties. The results provide insight into how robust and eco-friendly construction practices could be supported by increasing structural strength and thermal efficiency.

Sustainable development in the construction industry aims to improve the lifetime standards of present and future generations. Among industrial by-products, Ground Granulated blast Furnace Slag (GGBS) powder is employed as a cementitious material. This work investigates the properties of geopolymer binders prepared using the GGBS without conventional cement. The individual properties of the Geopolymer mortar (GPM) samples such as compressive strength and chemical composition were evaluated as per relevant IS Standards. Cubes of size (70.6×70.6×70.6) mm were cast and cured at ambient conditions for molarity 8M, 10M, and 12M with different fine aggregates, i.e., River sand, M-Sand, and GGBS. Compressive strength for 3, 7, and 28 days was evaluated. The results exhibit higher improvement in strength for 12M GPM’s with higher strength for river sand-based mixes. The chemical composition of GPM samples after 28 days of curing is determined. Essential chemical constituents such as SiO2 in 12M GPM’s considerably increased compared to 8M and 10M. The water absorption rate of samples with M-sand is greatly lowered with increasing molarity compared to those with river sand. The dry density of samples with M-sand exhibited higher improvement with increased molarity than those with river sand.

Seismic effect is one of the main factors which has to be considered during the design of structure. Earthquake is one of the supreme hazards for living and assets on earth. It is a natural phenomenon, occurring with uncertainties as a result of sudden release of energy within earth crust in the form of seismic waves. As the earthquake forces affects the stability of the building and about 60% of region in our country is under the influence of seismic forces, the buildings are provided with alternatives to withstand the horizontal forces and to increase the strength, stability and stiffness. Present paper investigates the performance of different structures provided with seismic resisting components. In this paper Shear walls and bracings are incorporated to make the structure moment resisting frame. A comparative seismic analysis of high-rise structures with and without shear walls and bracings is included in this discussion which is done using ETABS 2019 software by Response Spectrum Analysis. The parameters considered for analysis are natural frequency, natural time period, base shear, story stiffness, story displacement and story drift. in constructing both.
Once Upon a Time in Facilities Management
Authors: McCarroll Patricia , Hassard John
Published: August 2024

This book explores the storied spaces and narrative archetypes of a secondary business service, using facilities management (FM) as an example of non-core and increasingly outsourced organizational activities. The centrepiece is the development of artificial folklore, a research approach combining organizational analysis, storytelling, and folklore for interpretive purposes. An in-depth exploration of FM is developed; one exploring people, place, and process in a project revealing elements of organizational liminality as well as professional enchantment. This leads to concentration on the storytelling nature of secondary services, specifically utilizing the genre of fairytales to investigate narrative patterns within FM’s cultural environment. In the process, three modes of FM delivery are identified: consultancy provision, service provision, and in-house provision; modes which are narratively demarcated as professionals tell both deconstructed and reconstructed tales about their work. What is revealed is a recognized understanding across the three provider groups of their role as the ‘necessary evil’ of business organization, and notably as represented—in folkloric terms—by the shadow archetype. Ultimately, the artificial folklore approach developed in this book produces ghostwritten tales for each of the main FM provider streams; tales which reflect symbolically, the consultancy provider’s Hansel and Gretel, the service provider’s Goldilocks, and the in-house provider’s Cinderella organizational motifs. The outcome of this inquiry is a new diagnostic approach to the study of management, work, and organization—one linking elements of social theory, narrative analysis, and the business imaginary.
Our Moral Judgements Are All Wrong
Authors: Lenman James
Published: August 2024

Error theorists claim that moral judgements are all false but suppose that we have a morally neutral understanding of practical reason that can survive the wholesale rejection of morality and which we can employ in evaluating the options—abolitionism, fictionalism, etc.—for what we might, after embracing error theory, go on to do. This claim is contested. Many error theorists argue further that after we cease to believe in morality we still have abundant reason to continue to treat each other decently by adopting some kind of fiction which we make-believe is true. We do indeed have abundant reasons to treat each other decently but these are just the moral reasons the error theorist denies. We can make excellent sense of moral reasons along constructive expressivist lines explained in this book without resorting to the ropey metaphysics the error theorist agrees with the robust realist in taking morality to presuppose. It is robust realism, not morality, we need to reject. Constructive expressivism by taming the mystery that can seem to attach to such notions as irreducible normativity and external reasons robs error theory of its philosophical motivation and rescues morality from vulnerability to sceptical attack.
