Authors: Nepomnyashchev G. A. , Titov M. M. 
Published: August 2023

Due to the need of the construction industry for the intensification of various technological processes, it is necessary to reduce the time of specifying concrete parameters such as design, stripping, critical strength. It is relevant to develop technologies allowing to accelerate the process of setting the required strength parameters of concrete structures and increase them at specific time intervals.Activation technologies of cement suspensions, concretes and mortars are analyzed. The most promising and less studied directions in the strength properties improvement are identified.The aim of this work is to identify the physical impact on cement-containing materials to accelerate the strength gain in cement paste. A combination of several methods of electrophysical processing is used to develop the method of strength improvement and gain in cement paste. Electrophysical processing is based on electric polarization, electro-hydraulic shock and ultrasonic treatment.The paper proposes the most optimum mode for the water-cement suspension treatment, which provides a multiple increase in the strength gain in the first seven days, compared to the untreated suspension.The proposed electrophysical processing significantly improves the strength of hydrated cement and the best water-cement ratio is obtained to highly increase the concrete strength after seven days.

Authors: Kartopoltsev V. M. , Kartopoltsev A. V. , Alekseev A. A. 
Published: August 2023

The requirements for the plate-bearing test of bore piles are determined by technical regulations for the construction of pile foundations for bridge abutments. There is no information about the plate-bearing test reliability in the literature. Bridge pile foundations as bridge elements relate to strategic and economically responsible objects of the transport infrastructure in the Russian Federation and must have a high reliability level at the design stage and operation.Purpose: Practical application of the reliability theory for plate-bearing tests to ensure control for construction and economic expenditures.Approach: The probabilistic approach in providing plate-bearing test reliability is conditioned by a random nature of the stress-strain state of soil under the bore pile tip and nonfailure operating probability.Research findings: Probability density functions allow restrictions such as loading stages and time without the reliability reduction of plate-bearing tests and the possibility of using the experimental load–soil settlement relation to substantiate the program requirements and economic feasibility of works.

PENERAPAN GOOD MINING PRACTICE PADA AKTIVITAS PERTAMBANGAN EMAS DI SUMATERA BARAT
Authors: Anggraini Dewi , Islami Syaifuddin 
Published: August 2023

Penerapan Good Mining Practice (GMP) merupakan salah satu syarat dalam pemberian Izin Usaha Produksi (IUP) baik kepada perusahaan maupun kepada perseorangan dalam aktivitas pertambangan mineral dan batu bara (Minerba) di Indonesia, sebagaimana di atur oleh Undang-Undang Nomor 3 Tahun 2020. PT. Inexco Jaya Makmur (IJM) merupakan perusahaan pertambangan yang telah memperoleh IUP OP melalui Surat Keputusan Gubernur Sumbar Nomor 544/274/2017 tentang Persetujuan Peningkatan Izin Usaha Pertambangan Eksplorasi menjadi Izin Usaha Penambangan (IUP) Operasi Produksi Mineral Logam, dengan masa berlaku 2 Oktober 2017 s/d 31 Desember 2036 dengan wilayah operasional seluas 2.408 Ha yang berada di Jorong Sungai Beremas Nagari Cubadak Kecamatan Duo Koto Kabupaten Pasaman, akan tetapi IUP tersebut mendapat penolakan dari masyarakat Nagari Simpang Tonang karena 974 Ha wilayah IUP nya berada di Nagari Simpang Tonang. Penolakan tersebut berujung terjadinya konflik dan bentrokan antara masyarakat dengan perusahaan. Penelitian ini bertujuan untuk menjelaskan penerapan good mining practice dengan fenomena konflik pada pertambangan emas PT. IJM dengan masyarakat Simpang Tonang. Metode penelitian kualitatif dengan studi kasus. Pemilihan informan dengan purposive sampling, pengumpulan data dengan wawancara dan dokumentasi. Hasil penelitian menunjukan PT. Inexco Jaya Makmur (IJM) sebagai salah satu perusahaan pertambangan emas yang telah memperoleh sertifikat Clear and Clean (CnC) untuk saat ini belum bisa secara menyeluruh memenuhi syarat-syarat penerapan GMP, karena tahapan kegiatan yang telah dilaksanakan oleh PT. IJM masih pada tahapan persiapan/konstruksi. Sementara GMP akan terlihat pelaksanaanya secara menyeluruh jika telah memasuki tahapan penambangan/ekploitasi, kondisi ini juga diperparah dengan adanya penolakan masyarakat terhadap keberadaan PT. IJM di Nagari Simpang Tonang

Decidability in argumentation semantics
Authors: Dunne Paul E. 
Published: August 2023

Much of the formal study of algorithmic concerns with respect to semantics for abstract argumentation frameworks has focused on the issue of computational complexity. In contrast matters regarding computability have been largely neglected. Recent trends in semantics have, however, started to concentrate not so much on the formulation of novel semantics but more on identifying common properties: for example, from basic ideas such as conflict-freeness through to quite sophisticated ideas such as serializability. The aim of this paper is to look at the implications these more recent studies have for computability rather than computational complexity.

Background: Amyloid-β (Aβ) deposits asymmetrically early in Alzheimer’s disease (AD). This process is variable and has been associated with asymmetric hypometabolism. Objective: We investigated whether neural asymmetry during working memory and executive function processing was associated with AD genetic risk and markers of AD as well as other brain neuropathology biomarkers, cognitive function, and cognitive reserve in cognitively normal older adults. Methods: We analyzed data from 77 cognitively healthy, older adults who completed functional magnetic resonance imaging, positron emission tomography, and cognitive testing. We identified regions of significant activation and asymmetry during the Digital Symbol Substitution Task (DSST). We examined associations between regions with significant hemispheric asymmetry (directional and absolute) and global cerebral Aβ, cerebral glucose metabolism, white matter hyperintensities, APOE ɛ4 allele status, DSST reaction time, age, sex, education, and cognitive function. Results: Asymmetry was not associated with several factors including cognitive function, Aβ, and white matter hyperintensities. The presence of at least one ɛ4 APOE allele in participants was associated with less asymmetric activation in the angular gyrus (right dominant activation). Greater education was associated with less asymmetric activation in mediodorsal thalamus (left dominant activation). Conclusions: Genetic risk of AD was associated with lower asymmetry in angular gyrus activation, while greater education was associated with lower asymmetry in mediodorsal thalamus activation. Changes in asymmetry may reflect components of compensation or cognitive reserve. Asymmetric neural recruitment during working memory may be related to maintenance of cognitive function in cognitively normal older adults.

Published: August 2023

Background: Conventional neuroimaging biomarkers for the neurodegeneration of Alzheimer’s disease (AD) are not sensitive enough to detect neurodegenerative alterations during the preclinical stage of AD individuals. Objective: We examined whether neurodegeneration of the entorhinal-hippocampal pathway could be detected along the AD continuum using ultra-high-field diffusion tensor imaging and tractography for ex vivo brain tissues. Methods: Postmortem brain specimens from a cognitively unimpaired individual without AD pathological changes (non-AD), a cognitively unimpaired individual with AD pathological changes (preclinical AD), and a demented individual with AD pathological changes (AD dementia) were scanned with an 11.7T diffusion magnetic resonance imaging. Fractional anisotropy (FA) values of the entorhinal layer II and number of perforant path fibers counted by tractography were compared among the AD continuum. Following the imaging analyses, the status of myelinated fibers and neuronal cells were verified by subsequent serial histological examinations. Results: At 250μm (zipped to 125μm) isotropic resolution, the entorhinal layer II islands and the perforant path fibers could be identified in non-AD and preclinical AD, but not in AD dementia, followed by histological verification. The FA value of the entorhinal layer II was the highest among the entorhinal laminae in non-AD and preclinical AD, whereas the FA values in the entorhinal laminae were homogeneously low in AD dementia. The FA values and number of perforant path fibers decreased along the AD continuum (non-AD>preclinical AD > AD dementia). Conclusion: We successfully detected neurodegenerative alterations of the entorhinal-hippocampal pathway at the preclinical stage of the AD continuum.
Study on fluid friction loss on rotor surface of FeCo based high speed permanent magnet motor
Authors: Hou Peng , Ge Baojun , Tao Dajun , Pan Bo , Zhao Liping 
Published: August 2023

The linear speed of the rotor surface of high speed permanent magnet motor (HSPMM) is as high as 100 m/s, and the air friction loss on the rotor surface is much higher than that of ordinary motors, accounting for a large proportion of the total loss, and the actual air friction loss on the rotor surface is much higher than that of ordinary motors. It is extremely difficult to directly measure and verify the size of the rotor surface. At the same time, the air friction loss on the rotor surface is related to various factors such as motor speed, air gap structure and rotor surface roughness. It is difficult to accurately calculate through theoretical analysis and analytical methods. Based on the 3D fluid field physical model, this paper analyzes the relationship between the rotor air friction loss of FeCo based HSPMM and the rotor speed, rotor geometry, surface roughness and axial wind speed. Based on HSPMM, the calculation and test method of rotor surface air friction loss are studied. Through the FeCo based HSPMM no-load test, according to the relationship between the rotor air friction loss and other losses and the motor speed, the rotor surface air friction loss can be separated from the total loss. The experimental results are consistent with the calculated values, indicating that the HSPMM rotor air friction loss calculation method based on 3D fluid field analysis is effective.
PREREQUISITES FOR THE DEVELOPMENT OF INDUSTRIAL LANDS OF TERRITORIAL COMMUNITIES
Authors: Petrakovska Olha , Trehub Mykola 
Published: August 2023

Within the framework of the article, the main direction of research is aimed at increasing the efficiency of land use. Based on the analysis of the ratio of functional and target purpose, it can be concluded that increasing the efficiency of the use of industrial lands, first of all, depends on the solution of the following issues:
- target designation of land parcels occupied by industrial facilities; - actual use of land parcels for the specified purpose;- legal status of objects located on industrial lands.
Based on the above-mentioned components of effective use of territories, were systematized three most common cases. The first case is the best from the point of view of the further use of the land of the territorial community, because for the existing land parcel the category of industrial land, the type of functional purpose corresponds to the production zone. Such a case is ideal, it rarely occurs in practice, but it contains a few positive aspects in terms of ensuring the capabilities of territorial communities. Along with the land issue, the issue of filling the budget of the territorial community through land tax and personal income tax could be resolved, and the employment situation of residents could be improved.
The second case is the most common in practice. Several different options are possible: the actual use does not correspond to the functional and/or intended purpose and/or is not used at all, but the land parcel, real estate and land use subject have all legal identifiers. Territorial communities may not receive income due to incorrect calculation of payment amounts for land. Incorrect consideration and use of the zones of restrictions around regime-forming objects can negatively affect the owners and users of adjacent land parcels, or unreasonably limit the possible types of effective use of territories. If the land parcel and the object of immovable property are generally not in economic circulation, then in this case there are also certain risks for the community, similar to those mentioned above: lack of income, lack of opportunities for effective disposal of land, and inconsistency of the areas of effect of restrictions around regime-forming objects the actual situation.
The third case is not so common in practice, but it also occurs. The situation looks like this: the industrial object is used within the category, the intended purpose, considering the functional purpose of the corresponding territory, but due to various reasons, which may be of a historical nature, there are no legal documents for the land parcel and/or real estate and /or title-establishing documents of a legal entity. All this leads to inefficient use of land and lack of revenue to the budgets of territorial communities.
