Cardiovascular imaging analysis is a useful tool for the diagnosis, treatment and monitoring of cardiovascular diseases. Imaging techniques allow non-invasive quantitative assessment of cardiac function, providing morphological, functional and dynamic information. Recent technological advances in ultrasound have made it possible to improve the quality of patient treatment, thanks to the use of modern image processing and analysis techniques. However, the acquisition of these dynamic three-dimensional (3D) images leads to the production of large volumes of data to process, from which cardiac structures must be extracted and analyzed during the cardiac cycle. Extraction, three-dimensional visualization, and qualiﬁcation tools are currently used within the clinical routine, but unfortunately require significant interaction with the physician. These elements justify the development of new efficient and robust algorithms for structure extraction and cardiac motion estimation from three-dimensional images. As a result, making available to clinicians new means to accurately assess cardiac anatomy and function from three-dimensional images represents a definite advance in the investigation of a complete description of the heart from a single examination. The aim of this article is to show what advances have been made in 3D cardiac imaging by ultrasound and additionally to observe which areas have been studied under this imaging modality.

Gout is an arthritis characterized by the deposition of sodium monoacid crystals in the synovial membrane, articular cartilage, and periarticular tissues that leads to an inﬂamatory process. In most cases, the diagnosis is established by clinical criteria and analysis of the synovial fluid for MSU crystals. However, gout may manifest in atypical ways and make diagnosis difficult. In these situations, imaging studies play a fundamental role in helping to confirm the diagnosis or even exclude other differential diagnoses. Conventional radiography is still the most commonly used method in the follow-up of these patients, but it is a very insensitive test, because it only detects late changes. In recent years, advances in imaging methods have emerged in relation to gout. Ultrasound has proven to be a highly accurate test in the diagnosis of gout, identifying MSU deposits in articular cartilage and periarticular tissues, and detecting and characterizing tophi, tendinopathies, and tophi enthesopathies. Computed tomography is an excellent exam for the detection of bone erosions and evaluation of spinal involvement. Dual-energy computed tomography, a new method that provides information on the chemical composition of tissues, allows identification of MSU deposits with high accuracy. MRI can be useful in the evaluation of deep tissues not accessible by ultrasound. In addition to diagnosis, with the emergence of drugs that aim to reduce the tophaceous burden, imaging examinations become a useful tool in the follow-up treatment of gout patients.
Colorectal cancer staging with magnetic resonance imaging
Authors: Aluja Jaramillo Felipe , Upegui Jiménez Daniel
Published: October 2022

Colorectal cancer is the fourth leading cause of death worldwide and the fifth leading cause of cancer death in Colombia. Magnetic resonance imaging is the ideal modality for the evaluation of colorectal cancer, since it allows staging by determining invasion beyond the muscularis propria, extension towards adjacent organs, identification of patients who are candidates for chemotherapy or pre-surgical radiotherapy and planning of the surgical procedure. The key point is based on the differentiation between T2 and T3 stages through the use of sequences with high-resolution T2 information. In addition to this, it allows the assessment of the size and morphology of the lymph nodes, and considerably increases the specificity for the detection of lymph node involvement. MRI is a technique with high specificity and high reproducibility.

Published: October 2022

Objective: To evaluate the imaging features of spondyloarthritis on magnetic resonance imaging (MRI) of the sacroiliac (SI) joints in terms of topography (in thirds) and affected margin, since this aspect is rarely addressed in the literature. Methods: Cross-sectional study with MRI (1.5 T) evaluation of the SI in 16 patients with diagnosis of axial spondyloarthritis regarding the presence of acute (subchondral bone edema, enthesitis, synovitis and capsulitis) and chronic changes (erosions, subchondral bone sclerosis, bone bridging and fatty replacement), performed by two radiologists, blinded to clinical data. MRI findings were correlated with clinical data including age, disease duration, medications, HLA-B27, BASDAI, ASDAS-VHS and ASDAS-PCR, BASMI, BASFI, and mSASSS. Results: Bone edema pattern and erosions showed predominance in the upper third of SI (p = 0.050, p = 0.0014, respectively). There was a correlation between the time of disease and structural changes by affected third (p = 0.028-0.037), as well as the presence of bone bridges with BASMI (p = 0.028) and mSASSS (p = 0.014). Patients with osteitis of the lower third had higher ASDAS values (ESRV: p = 0.011 and CRP: p = 0.017). Conclusion: Chronic inflammatory changes and the pattern of bone edema predominated in the upper third of the SI, but there was also concomitant involvement of the middle or lower thirds of the joint. The localization of involvement in the upper third of the SI was insufficient to differentiate between degeneration and inflammation.
Magnetic resonance imaging: Recent research on the biological impacts of static magnetic and high-frequency electromagnetic fields
Authors: Pophof Blanka , Brix Gunnar
Published: October 2022

Problem: in recent years, new studies have been published on biological effects of strong static magnetic fields and on thermal eﬀects of high-frequency electromagnetic fields as used in magnetic resonance imaging (MRI). Many of these studies have not yet been incorporated into current safety recommendations. Method: scientific publications from 2010 onwards on the biological effects of static and electromagnetic fields of MRI were searched and evaluated. Results: new studies confirm older work that has already described effects of static magnetic fields on sensory organs and the central nervous system accompanied by sensory perception. A new result is the direct effect of Lorentz forces on ionic currents in the semicircular canals of the vestibular organ. Recent studies on thermal effects of radiofrequency fields focused on the development of anatomically realistic body models and more accurate simulation of exposure scenarios. Recommendation for practice: strong static magnetic fields can cause unpleasant perceptions, especially dizziness. In addition, they can impair the performance of the medical personnel and thus potentially endanger patient safety. As a precaution, medical personnel should move slowly in the field gradient. High-frequency electromagnetic fields cause tissues and organs to heat up in patients. This must be taken into account in particular for patients with impaired thermoregulation as well as for pregnant women and newborns; exposure in these cases must be kept as low as possible.

Published: October 2022

Multiple myeloma (MM) is a hematologic cancer characterized by clonal proliferation of plasma cells within the bone marrow. It is the most serious form of plasma cell dyscrasias, whose complications—hypercalcemia, renal failure, anemia, and lytic bone lesions—are severe and justify the therapeutic management. Imaging of bone lesions is a cardinal element in the diagnosis, staging, study of response to therapy, and prognostic evaluation of patients with MM. Historically, the skeletal radiographic workup (SRW), covering the entire axial skeleton, has been used to detect bone lesions. Over time, new imaging techniques that are more powerful than SRW have been evaluated. Low-dose and whole-body computed tomography (CT) supplants SRW for the detection of bone involvement, but is of limited value in assessing therapeutic response. Bone marrow MRI, initially studying the axial pelvic-spinal skeleton and more recently the whole body, is an attractive alternative. Beyond its non-irradiating character, its sensitivity for the detection of marrow damage, its capacity to evaluate the therapeutic response and its prognostic value has been demonstrated. This well-established technique has been incorporated into disease staging systems by many health systems and scientiﬁc authorities. Along with positron emission tomography (PET)-18 ﬂuorodeoxyglucose CT, it constitutes the current imaging of choice for MM. This article illustrates the progress of the MRI technique over the past three decades and situates its role in the management of patients with MM.

Authors: Quesada José Fernando Aceves , Gabrie Legorreta Paulín , Hubp José Lugo , Romero Juan Umaña , Cuevas Héctor Alfredo Legorreta
Published: October 2022

With the purpose of strengthening the knowledge and prevention of landslide disasters, this work develops a methodology that integrates geomorphological mapping with the elaboration of landslide susceptibility maps using geographic information systems (GIS) and the multiple logistic regression method (MLR). In Mexico, some isolated works have been carried out with GIS to evaluate slope stability. However, to date, no practical and standardized method has been developed to integrate geomorphological maps with landslide inventories using GIS. This paper shows the analysis carried out to develop a multitemporal landslide inventory together with the morphometric analysis and mapping technique for the El Estado River basin where, selected as the study area, is located on the southwestern slope of the Citlaltepetl or Pico de Orizaba volcano. The geological and geomorphological factors in combination with the high seasonal precipitation, the high degree of weathering and the steep slopes predispose its surfaces to landslides. To assess landslide susceptibility, a landslide inventory map was prepared using aerial photographs, followed by geomorphometric mapping (altimetry, slopes and geomorphology) and field work. With this information, landslide susceptibility was modeled using multiple logistic regression (MLR) within a GIS platform and the landslide susceptibility map was obtained.
Characterization of soil suitability in the province of Catamarca using geographic information systems
Authors: Trabichet Florencia Cecilia
Published: October 2022

Land suitability analysis using geographic information systems (GIS) is one of the most widely used method today. In this type of studies, GIS and geo-spatial statistical tools are used to evaluate land units and present the results in suitability maps. The present work aims to characterize the suitability of soils in the province of Catamarca for pecan nut production according to the variables: rockiness, salinity, risk of water-logging, depth, texture and drainage described in the Soil Map of Argentina at a scale of 1:500,000 published by the National Institute of Agricultural Technology. A classification of the suitability of the soil cartographic units was made according to crop requirements, applying the methodology proposed by FAO. The standardization of variables made by omega score and the calculation of the spatial classification score were carried out as a result of the synthesis of the spatial distribution of soil suitability. The applied methodology allowed obtaining the soil suitability map resulting in a total of 60,662 km2 suitable for pecan nut production, which accounts for 59.8% of the total area of the province.
Digital cartography of soil classes with fuzzy logic in mountain areas
Authors: Valera Ángel R. , Pineda María C. , Viloria Jesús A.
Published: October 2022

In order to strengthen the study of soil-landscape relationships in mountain areas, a digital soil mapping approach based on fuzzy set theory was applied. Initially, soil properties were estimated with the regression kriging (RK) method, combining soil data and auxiliary information derived from a digital elevation model (DEM) and satellite images. Subsequently, the grouping of soil properties in raster format was performed with the fuzzy c-means (FCM) algorithm, whose final product resulted in a fuzzy soil class variation model at a semi-detailed scale. The validation of the model showed an overall reliability of 88% and a Kappa index of 84%, which shows the usefulness of fuzzy clustering in the evaluation of soil-landscape relationships and in the correlation with soil taxonomic categories.
Cartographic determination of the dry stone walls of the Mallorcan Tramuntana mountain range (Balearic Islands): Exploratory analysis
Authors: Alomar-Garau Gabriel , Gelabert Miquel Grimalt , Llinàs Joan Bauzà
Published: October 2022

The construction technique of dry stone, declared Intangible Cultural Heritage of Humanity by UNESCO, has historically materialized in Mallorca in the form of a varied range of constructions with different functions. The massive construction of dry stone walls in the Mallorcan countryside has left an outstanding landscape and territorial imprint, which constitutes a rich source of geographical analysis. An unpublished cartography of the walls located in the Serra de Tramuntana mountain range in Mallorca is presented as an essay, a cartography that has served as a basis for their classification and provisional quantification. With the support of basic cartographic, photo-interpretation and GIS techniques, the detailed examination of two official cartographic bases has allowed us to determine their usefulness as reliable sources for locating and understanding the dry stone walls in our study area, with a view to a more far-reaching geographical study of them.
The systemic approach to risk analysis in geography
Authors: Principi Noelia
Published: October 2022

This paper presents a brief review of risk studies in Geography since the beginning of the 20th century, from approaches focused on physical-natural components or social aspects, to perspectives that incorporate a systemic approach seeking to understand and explain risk issues at a spatial level. The systemic approach considers principles of interaction between multiple variables and a dynamic organization of processes, as part of a new formulation of the scientific vision of the world. From this perspective, the Complex Systems Theory (CST) is presented as the appropriate conceptual-analytical framework for risk studies in Geography. Finally, the analysis and geographic information integration capabilities of Geographic Information Systems (GIS) based on spatial analysis are explained, which position it as a fundamental conceptual and methodological tool in risk analysis from a systemic approach.

Authors: Mária Péter H.
Published: October 2022

Zoltán Vámossy (1868–1953), with Transylvanian roots, became a doctor 130 years ago, in 1891, at the University of Budapest. Later, from 1898, he was appointed a private university professor of Pharmacology, from 1908 a public university professor, and from 1920 to 1938 he was director of the Institute of pharmacology. In the meantime, from 1922 to 1924, he also held the position of dean of the Faculty of Medicine. He was elected a corresponding member of the Hungarian Academy of Sciences on May 5, 1920, but on April 23, 1948 his membership was terminated for political reasons. It was not restored until after his death, on 9 May 1991. Afterwards he taught even in the 1945/46 school year. He was an understanding and helpful instructor for the university students, so he was respected, appreciated, and loved. His professional life was filled with university education, academic work, and editorial duties. He wrote books to promote education, for example he translated into Hungarian a book written by Arnold Cloetta and Wilhelm Filehne in 1881, entitled Lehrbuch der Arzneimittellehre und Arzneiverordnungslehre. This was published in 1894 in Budapest under the title Gyógyszertan tankönyv (Pharmacology Textbook). In 1907 he published his own book Mérgezésekről (On Poisonings), and in 1908 Gyógyszertan orvostanhallgatók és orvosok számára (Pharmacology for medical students and physicians). The latter’s ninth, expanded and revised edition appeared in 1944. Medical students in Hungary and Transylvania learned from this for decades. In 1933 he was appointed chairman of the editorial board of the IV. Magyar Gyógyszerkönyv. His editorial work is also significant. From 1909 to 1944 he was the commissioned editor of the new course of the Magyar Orvosi Archivum (Hungarian Medical Archive), and from 1923 to 1944 he was the editor-in-chief of the Orvosi Hetilap (Medical Weekly). During this time, many of his writings were published here. In December 1927 issue, he announced that certain issues of the Orvosi Hetilap would be supplemented by a permanent supplement entitled Az Orvosi Gyakorlat Kérdései (Questions of Medical Practice). In 1940, in parallel with the Medical Weekly, he founded the monthly Orvostudományi Közlemények (Medical Gazette), which was published until the end of 1944. He strived for the correct use of the Hungarian medical language in all his writings..

Published: October 2022

The aim of our research was to prepare polymer-free hydroxypropyl-β-cyclodextrin-(HPβCD) and sulfobutylether-β-cyclodextrin (SBEβCD) based nanofibers. For this purpose, four-four viscous, aqueous solutions were prepared with different concentrations from each cyclodextrin derivative, with the following concentrations: 170, 180, 190 and 200% (v/w) from HPβCD and: 210, 220, 230 and 240% (v/w) from SBEβCD.

The parameters for the electrospinning process were: 1.5 ml/h flowrate, 22-24 G sized needle, and an applied voltage of 25 kV. The distance between the needle and the collector was 13-15 cm in the case of HPβCD, and 9-11 cm in the case of SBEβCD.

The obtained nanofibers were morphologically characterized and their dis-integration process was also tracked. Then, the results obtained were compared within each cyclodextrin group, in order to identify optimal spinning parameters and they were also discussed, based on previous reports.

From our results, we concluded that the 200% HPβCD solution is the most effective for nanofiber formation, producing smooth, homogenous fibers with small diameters, which present ideal disintegration properties. At the tested voltages, it was not possible to form ideal nanofibers from SBEβCD, however, we managed to form some nanofibers with acceptable quality, and the ones made out from the 240% solution of the SBEβCD were the most suitable.

Published: October 2022

Poliomyelitis is a contagious disease characterized by the appearance of fever, malaise, scratching in the throat, gastrointestinal signs, and after a few days the appearance of muscle paralysis, as well as respiratory and vasomotor disorders. Today, this disease is very rare, due to systemic active immunization. The aim of this study was to assess the level of knowledge and attitudes toward poliomyelitis and importance of immunization against it.

A specially designed survey questionnaire was used for interviewing purposes. Data analysis and processing were performed using a statistical data processing package (SPSS for Windows, version 20). A chi-square test was used from the statistical tests.

The educated profile of the respondents was as follows: medical sciences - 37 (50%), natural sciences and mathematics - 6 (8,1%), social sciences - 5 (6,8%), technical sciences - 19 (25,7%) and arts - 7 (9,5%). The study findings indicate a high level of awareness and knowledge of the population regarding polio, as well as good health awareness of the population about immunization i.e. polio vaccination. 34 respondents from the field of medical education answered the question exactly how the vaccine protects against the disease. In the field of natural mathematical sciences, a total of 3 gave the correct answer, which makes 50% of the total number of persons (6) in the mentioned field. In addition, majority of the study sample (70,3%) is aware that child should be vaccinated. Furthermore, 91,9% of respondents agree that education of parents regarding children vaccination is of great importance for whole community.

Based on findings of present study it can be concluded that efforts still need to be made in education of the wider population toward polio and the importance of vaccination. In addition to healthcare professionals, the entire community should participate in this strategic task.
The Role of Galectin 3 in the Pathogenesis of Diabetes Mellitus: Focus on Β-Cell Function and Survival
Authors: Marinkovic Milos , Petrovic Ivica
Published: October 2022

Galectin 3 is a lectin expressed in many tissues with a significant biological role in physiological and pathological processes. Our review aims to sublimate the effects of galectin 3 on the β-cells function and survival. Data about the effect of galectin 3 on β- cells are scarce and contradictory. Several studies have shown that reduced activity of the galectin 3 gene reduces the risk of developing type 1 diabetes in an experimental model of diabetes in galectin 3 deficient mice. On the other side, in an experimental model of type 1 diabetes with mice with selectively enhanced expression of galectin 3 in β-cells, was shown that increased expression of this lectin has a protective role. Unlike type 1 diabetes where the autoimmune process plays a dominant role in pathogenesis, the pathogenesis of type 2 diabetes is multifactorial. One of the main factors which contribute to type 2 diabetes, the insulin resistance, is related to the concentration of soluble galectin 3. The effect of galectin 3 is very important for β-cell function. When a harmful factor acts on a β-cell, its intracellular concentration increases to preserve the function of β-cells and prevent their apoptosis, by blocking the internal path of apoptosis. However, excessive accumulation of galectin 3 inside the cell leads to its secretion, which encourages tissue inflammation. Based on all the above, galectin 3 has a double effect on β-cells.
FOREIGN VESSEL SINKING POLICY IN ERADICATING ILLEGAL, UNREPORTED, AND UNREGULATED (IUU) FISHING IN THE INDONESIAN EXCLUSIVE ECONOMIC ZONE (IEEZ)
Authors: Khalik Richard Al , Roesa Nellyana
Published: October 2022

The relevance of foreign vessel sinking policy to eradicate IUU fishing in IEEZ by national regulation to UNCLOS 1982 is questionable. This paper uses a normative legal analysis,  examining international conventions and national regulation provisions and their application to legal events. The results indicate that implementing the foreign vessel sinking policy is national law enforcement of  Law No. 45 of 2009 amendment to the  Law No. 31 of 2004 Concerning Fishery,  Article 69 (1) and (4). The foreign vessel sinking policy is not contrary to UNCLOS 1982 because the subject protected in EEZ by Article 73 (3) is the human being, not the vessel. It remains an effective means to create a deterrent effect as an optimum penalty for such crime.
APPLICATION OF HARDSHIP RULE UNDER THE UNIDROIT PRINCIPLES OF INTERNATIONAL COMMERCIAL CONTRACTS IN INDONESIA
Authors: Skd Fikri Farokhi. , Sanusi Sanusi
Published: October 2022

This article examines the concept of hardship rule based on the UNIDROIT Principles of International Commercial Contracts (hereinafter called UPICC) and how it compares with force majeure regulated by the Indonesian Civil Code (hereinafter called ICC), as well as to analyze how it is applied in the Indonesian court decisions. This study uses a normative legal research method. The study shows that the meaning of the hardship rule under the UPICC is an event that has fundamentally changed the balance of a contract, resulting in a very high implementation value for the party performing, or the value of the implementation of the agreement is drastically reduced for the receiving party. Hardship and force majeure both occur in circumstances that preclude the obligation to perform that cannot be anticipated in advance, and the fault of either party does not cause the situation. The hardship rule emphasizes changes in circumstances by one of the parties to the contract caused by the contract value that changes significantly, causing significant losses for one of the parties, and hardship offers renegotiation for the parties. Meanwhile, force majeure is emphasized when the parties are unable to carry out all or part of the agreed performance which is generally caused by natural and social events, and force majeure offers contract suspension and termination of the contract. Indonesia has implicitly implemented this hardship in the legal system by referring to the principle of justice.
Magnetic Levitation Technology As An Object Floating Technique In Wooden Craft
Authors: Sumino Sumino , Romadhon Achmad Gilang
Published: October 2022

Research and application of magnetic levitation have been expanded in electric motors, generators, radar monitoring systems, car-door central locks, and metal object towing devices. In the operation, the objects do not touch each other. The use of a magnet-based system that floats objects is called a levitation system. In earlier times, fine art had been comfortable with its structure. Consequently, it is not prepared to deal with electromagnetic technology systems. Magnetic levitation technology is the process of floating objects with a gravitational force that rejects or counteracts each other in a magnetic field. This research aims to provide innovations in applying magnetic levitation in designing fine artworks in Indonesia, mainly wooden crafts. The work was designed with eco-design methods. The magnetic levitation techniques have been widely applied in woodcraft art today. The process of floating objects in the air has the property of rejecting each other's components, while the use of permanent magnets sets the object's position stable. Wood material as an object medium is formed to resemble a flying bird stabilized by magnetic levitation techniques. This wooden crafts experiment featured objects spinning and hovering when exposed to the wind.
Исследование Золотарёвского городища VIII-XIII вв. Михаилом Романовичем Полесских
Authors: Иконников Дмитрий Сергеевич , Соболь Ариэль Станиславович
Published: October 2022

Золотарёвское городище (VIII–XIII вв.) представляет собой часть большого археологического комплекса эпохи средневековья. Оно относится к группе памятников булгарского типа. В 1952, 1953, 1957, 1959, 1965, 1976 и 1977 годах памятник исследовался Михаилом Романовичем Полесских (1908–1992). Этот исследователь первым определил научный потенциал археологического памятника. М.Р. Полесских не смог при жизни обобщить результаты своих работ на Золотарёвском городище. После смерти исследователя такие попытки предпринимались Г.Н. Белорыбкиным (в 2001 и 2020 годах). Однако эта работа не была доведена до конца. До настоящего времени не существует детальной реконструкции планиграфии результатов раскопок М.Р. Полесских на территории Золотарёвского городища. В данной статье восстановлена хронология археологических работ на археологическом памятнике. В 1952, 1953 и 1957 годах М.Р. Полесских заложил ряд шурфов на территории IV сектора городища. В 1959, 1965 и 1976–77 годах были проведены масштабные раскопки на территории всех секторов памятника. Наиболее полно была исследована мысовая часть Золотарёвского городища между стрелкой мыса и первым валом. На памятнике были обнаружены следы не менее четырёх сооружений (два – в секторе IV, два – в секторе I). Все они были интерпретированы М.Р. Полесских как жилые площадки. В 1965 и 1977 годах была исследована стратиграфия двух валов. Результаты всех этих работ введены в научный оборот только частично.
Из истории исследований археологических памятников средневекового и Нового времени г. Набережные Челны
Authors: Набиуллин Наиль Гатиатуллович , Салахатдинова Гузель Тимерзяновна
Published: October 2022

В статье представлены новые материалы по истории исследований археологических памятников средневековья и Нового времени г. Набережные Челны. Обращение к первичным полевым источникам и другим материалам предшествующих исследований в совокупности с новыми данными позволило подтвердить сделанный ранее вывод о вполне представительном по меркам булгарской периферии булгаро-татарском присутствии на территории и окрестностях современного г. Набережные Челны. Имеющиеся материалы иллюстрируют продолжение начавшегося еще в домонгольское время освоения камских притоков в последующий золотоордынский период. Обычное закрепление на доминирующих естественных высотах, площадках мысов вписывается в контекст Камской коммуникации, контроля одного из ее участков. Рядом с укрепленными пунктами появлялись поселения, формировалась инфраструктура. Доминирование роли естественного фактора в древности, средневековье, новое время обусловило преемственность в выборе мест для проживания, в том числе первоначальных поселений, особенно укрепленных. В определенной степени сохранялся характер использования конкретных участков, соответствующий их функциональной сути. Территория, динамика формирования культурного слоя в средневековье и Новое время пока не определены. На исследованных участках не выявлены выразительные материалы XVII в., в том числе не локализованы первоначальные Челнинский починок, Бережная слобода, известные по письменным источникам. Последнее важно отметить в целях корректного сравнения представленности материалов Нового и средневекового времени. Общеизвестно, что последние изначально откладываются на порядки меньше по сравнению с поздними, сохраняются хуже, выявляются сложнее и т.д.
О ремесленном производстве на булгарских селищах XI – начала XIII в.
Authors: Руденко Константин Александрович
Published: October 2022

В статье рассматриваются вопросы, связанные с изучением ремесел на неукрепленных поселениях Волжской Болгарии. В первом исследовании на эту тему Е.П. Казаков, предположил, что на селищах, располагавшихся в нижнем течении Камы, во второй половине Х – первой половине XI в. существовали различные ремесла, включая кузнечное и ювелирное. Он утверждал, что на Семеновском селище изготавливали стеклянные бусы, а на V Старокуйбышевском – медные котлы, кумганы, ковши. Однако мест, где находились металлургические горны, плавилось стекло и изготавливалась металлическая посуда не было выявлено. Автор утверждает, что археологические доказательства плавки железа имеются на Остолоповском и Лаишевском селищах – металлургические шлаки, крицы, остатки горнов. На последнем имеются следы плавки меди, а также переработки вышедшей из употребления медной посуды. Мастерская ювелира функционировала на Остолоповском селище. Автор считает, что сельские кузнецы нередко приобретали на рынке заготовки изделий и из них изготавливали некоторые мелкие артефакты, например, накладки и пряжки. Основной их продукцией были гвозди и скобы. Таким образом, развитие ремесленного производства на селищах было связано с рядом факторов: составом населения, расположением поселения, его статусом и временем существования. Крупные сельские центры, как, например, Лаишевское селище, обеспечивали кузнечной продукцией расположенные рядом поселения. Домашнее керамическое производство существовало на большинстве селищ, в отличие от производства изделий из кости и рога, которых на селищах немного.
