Retrospective Analysis of 101 Canine Lymphoma Cases Diagnosed in Surgical biopsies in Latvia (2011–2020)
Authors: Houtana Ilze Matise-Van , Geine-Romanova Lilija 
Published: January 2023

Abstract
Lymphoma is a malignant tumor commonly diagnosed in dogs representing 7–24% of all canine tumors. There has been no previous studies focused on characterization of canine lymphoma cases in Latvia. The goals of this retrospective study were to determine prevalence and characteristics of lymphoma cases among biopsy submissions to a private veterinary pathology service that receives approximately 80% of all biopsy submission in Latvia and to compare this data with published canine lymphoma reviews. Data were retrieved to select records from Latvian dogs diagnosed with lymphoma between 2011 and 2020, determining characteristics of dogs and types of lymphoma based on anatomic distribution and cellular morphology. In a ten-year study period, diagnosis of lymphoma constituted 1–4% of surgical biopsy submissions each year without upwards trend. Affected dogs were middle age (median 8 years; range 2–13), with a slight male predominance (58%). The majority of dogs (19%) were mixed breed. Top 3 affected dog breeds were Rottweiler, American Staffordshire terrier and French bulldog with 6–7 cases in each breed. Multicentric form of lymphoma predominated (55%) followed by alimentary and mucocutaneous lymphoma (21% and 14%, respectively). Within multicentric form of lymphoma two thirds were intermediate to large cell lymphomas. Included in this group would be diffuse large B cell lymphomas, the most common subtype of canine lymphomas; however, lack of immunohistochemical testing precluded complete lymphoma classification according to WHO guidelines. Results of this study correlate well with the previously published results and provide important information to Latvian small animal veterinarians and pathologists.

Abstract
Bumblebee activity interaction with solar irradiation, solar irradiation and HPS lighting irradiation, the HPS effect of photoperiod, day temperature and hive density were assessed with tomato fruit weights in a commercial tomato glass greenhouse in 2020–2021. Pollination activity was measured by observing ten randomly chosen cv. ‘Beorange’ tomato plants and by counting bumblebee bruised tomato flowers. MANOVA was conducted between factors and bee activity, followed by Pearson’s correlation. A Mann-Whitney U test was calculated to determine the significance between tomato flower bruising levels and fruit weights, followed by Cliff’s delta (d). Pollination activity decreased mainly in December and January when solar irradiation decreased to below 110 J cm−2 day−1. Bumblebee activity was significantly affected by solar irradiation with HPS lighting (p<0.001; p<0.01). There was a significant correlation between bumblebee activity and solar irradiation (r= 0.75; p<0.05), and solar irradiation with HPS lighting (r= 0.70; p<0.05). There was no correlation between bumblebee activity and fruit weights (r= −0.20; p<0.05). Bruised flowers had significantly greater fruit weight increases (165.7 g) compared to unbruised flowers (123.4 g) (d= 0.12; p<0.05). Bee activity rates between 60% to 80% can be concluded as an effective rate for tomato growers. Bumblebees need at least 110–154 J cm−2 day−1 of solar irradiation to achieve a high pollination activity rate in temperate climate zones during the winter season.

Abstract
This study describes dynamics in hydrology, morphometry, and water mass movement in Lake Kisezers. The analysis of Lake Kisezers’ morphometry dynamics according to the rapidly changing environment has been carried out. The determination of dynamics in morphometry comes before understanding potential exploitation and environmental sustainability of water body. Lake Kisezers is situated in a densely populated area. Without understanding and deciphering all possible environmental factors influencing Lake Kisezers, the water body can degrade and become of poor environmental quality. Such changes can lead to irreversible changes in the lake ecosystem and degradation of the surrounding landscape. This study aims to identify and explain the elements that influence Lake Kisezers’ hydrological regime, catchment area, and bathymetry. Lake Kisezers is hardly influenced body of water with rapid hydrological and morphometric dynamics. The research is possible due to extensive data availability and the importance of the water body location. Lake Kisezers affects the city of Riga and its surrounding area with a danger of flooding and decreasing land exploration potential. This study results in better understanding in the factors influencing hydrology and morphometry in Lake Kisezers and possible environmental sustainability endangerment in the future. The main impact factor is the connectivity to the River Daugava and its unique hydrological regime. For Lake Kisezers, environmental balance is necessary to continue research and develop a hydrological change model. This study was conducted with fieldwork data and open-source cartographic, geospatial, water level, and mass movement data. The research seeks to understand what is necessary to maintain environmental sustainability in Lake Kisezers.

Abstract
The aim of the publication is to develop theoretical and methodological foundations and practical recommendations for determining the efficiency of biotechnological processes with the subsequent justification of technical parameters to ensure a high level of viability of bio-objects. In the course of the conducted scientific research, the criteria of quality function were defined and formalised, in accordance with which the conditions of biotechnological processes of laser division of embryo were formulated as a single case in the realisation of the economic mechanism of biotechnology. This makes it possible to ensure a high level of cattle (cattle) productivity, reduce the time for the reproduction of livestock and reduce the costs of movement, trade and transportation of cattle. The quality function of the biotechnological process of laser division of embryo is formulated on the basis of criterion of non-exceeding of the temperature field in cells of blastomeres and the predetermined acceptable value that allowed one to take into account the main parameters and to propose the criterion of biotechnological process optimisation. As a promising task for the development of the bioeconomy as an economic mechanism in implementing biotechnologies, the necessity of determining the quality function by formalising the integral indicator of efficiency has been established, This enables one to ensure a high level of commercialisation of biotechnologies, to increase the productivity of agricultural animals, and to suggest alternative methods for the quick renewal of livestock.

Elang Jawa (Nisaetus bartelsi) merupakan raptor endemik Pulau Jawa yang terancam punah dan dilindungi hukum. Taman Nasional Alas Purwo (TNAP) merupakan habitat elang jawa di kawasan dataran rendah. Terbatasnya informasi tentang preferensi habitat elang jawa di TNAP menyebabkan sulitnya menyusun rencana pengelolaan habitat elang jawa yang sesuai dengan preferensi habitatnya di alam. Tujuan penelitian ini adalah menganalisis karakteristik lanskap dan karakteristik vegetasi yang mempengaruhi aktivitas elang jawa sehingga dapat digunakan untuk rekomendasi pengelolaan habitat elang jawa di TNAP. Data yang dikumpulkan terdiri dari karakteristik lanskap dan karakteristik vegetasi yang didapatkan dari wawancara pengelola dan observasi. Karakteristik lanskap habitat bersarang dibedakan oleh kondisi kemiringan dan elevasi. Habitat bersarang memiliki kemiringan < 8 % dan elevasi 36 - 74 mdpl serta ditemukan aliran sungai. Sementara itu, habitat berburu berada di kemiringan < 8 % - 40 % dan elevasi 0 - 167 mdpl. Jenis tutupan lahan berupa hutan alami lebih disukai elang jawa untuk bersarang ataupun berburu, serta habitat yang digunakan tidak berjauhan dengan aktivitas manusia. Karakteristik vegetasi pada habitat bersarang dan berburu dibedakan oleh keberadaan pohon tinggi yang menjadi preferensi pohon sarang elang jawa. Arsitektur pohon model rauh dan strata A lebih disukai sebagai pohon sarang, sedangkan pohon berburu banyak menggunakan pohon berstrata A dan B dengan arsitektur pohon didominasi model rauh. Habitat yang digunakan juga didominasi oleh pohon buah yang disukai oleh mangsa elang jawa. Rekomendasi pengelolaan habitat elang jawa di TNAP dapat dilakukan kegiatan restorasi dengan menanam jenis pohon yang memiliki karakter berstrata A dan B, emergent tree, arsitektur pohon model rauh, dan vegetasi yang merupakan pakan dari mangsa elang jawa.

Статья посвящена исследованию монетного комплекса, представленного четырьмя пражскими грошами эмиссии Вацлава IV, обнаруженного в окрестностях г. Гаврилов Посад Ивановской области в 1998 г. как случайная находка. На протяжении XIV столетия в границах Европы пражские гроши выполняли функцию международного средства расчета. Длительное время эти монеты использовались в качестве основной денежной единицы Великого княжества Литовского. Находки пражских грошей в пределах России в основном связаны именно с областями, некогда входившими в состав Литовского государства. Исключением является обнаружение чешской валюты в границах бывшей Новгородской республики, где она, согласно летописным текстам, с 1410 по 1420 г. использовалась в качестве официальной внутренней денежной единицы. Зарегистрированные в Суздальском Ополье пражские гроши являются самыми восточными на сегодняшний день находками таких монет в Европе. Их публикация расширяет представление о масштабах оборота грошей, выполнявших, вероятно, функцию торговой монеты и в русских княжествах.
This paper is devoted to studying the coin range, represented by four Prague groschens issued by Wenceslaus IV and discovered in 1998 as a chance archaeological finding in the vicinity of Gavrilov Posad, the Ivanovo Region. During the 14th century the Prague groschens functioned as an international means of payment within the borders of Europe. These coins had been used as the main currency of the Grand Duchy of Lithuania for a long time. The Prague groschens found within the Russia borders are mainly connected with the areas which once had been a part of the Lithuanian state. The only exception is the discovery of Czech currency within the borders of the former Novgorod Republic, where, according to the chronicles, it was used as the official domestic currency from 1410 to 1420. The Prague groschens registered in Suzdal Opole have been the eastermost artefacts of such coins in Europe so far. Their publication expands the insight into the circulation scale of groschens, which probably performed the function of trade coins in the Russian Duchies as well.

В статье представлены результаты рамановского анализа химического и структурного состава фрагментов импортного глазурованного кувшина из раскопок в Муроме. Исследованы кроющая глазурь и пигменты, использованные при его росписи. Полученные результаты позволяют объективно определить место и время изготовления находок (Изник, Турция, XVI в.). Выявлены характерные особенности такой керамики, которые могут позволить атрибутировать находки ее фрагментов на основе материалов, использованных в красках: уваровита в оливково-зеленом линейном орнаменте, силиката кобальта со структурой оливина в синем фоне, окрашенного карбонатом меди стекла (smalt) в бирюзовых элементах росписи, аморфного углерода и хромита железа со структурой шпинели в черных линиях. Белый ангоб содержит переходные структуры, образовавшиеся при обжиге керамики. Их наличие позволяет оценить температурный режим обработки изделий в средневековых мастерских Изника.
The article presents the results of Raman analysis of the chemical and structural composition of fragments of an imported glazed jug from excavations in Murom. The covering glaze and pigments that were used in its painting have been investigated. The obtained results make it possible to objectively determine the place and time of making the finds (Iznik, Turkey, 16th century). The revealed characteristic features of such ceramics can help to attribute the finds of its fragments based on the materials used in the paints. There are uvarovite in olive green linear ornament, cobalt silicate with olivine structure in a blue background, smalt colored with copper carbonate in turquoise elements of painting, amorphous carbon and iron chromite with a spinel structure in black lines. White engobe contains transitional structures formed during ceramic firing. Their presence makes it possible to estimate the temperature conditions of a products processing in Iznik’s medieval workshops.
THE NECROPOLIS OF THE ANCIENT TOWN OF VLADIMIR ON THE TERRITORY OF THE PATRIARCH’S GARDEN BASED ON THE RESULTS OF ARCHAEOLOGICAL RESEARCH IN 2016-2017

Статья освещает варианты погребального обряда городского некрополя древнего Владимира, обнаруженного и исследованного в ходе охранных археологических раскопок 2016-2017 гг. на территории учебного комплекса «Патриарший сад» г. Владимира. Могильник расположен на высоком мысу, образованном южным склоном левого берега р. Клязьма и склоном рельефной впадины, на которой находится сад. Древнее кладбище локализовано на площади не менее 1000 м². Захоронения располагались в три яруса. Поздние захоронения, зафиксированные в культурном слое, выполнены по христианскому погребальному обряду, их датировка - вторая половина XIII - XV в. Ранние захоронения XII - начала XIII в. выполнены в могильных ямах, впущенных в материк. В этих захоронениях при преобладании христианской обрядности встречены черты иных вариантов погребального обряда: захоронение в бересте, захоронение с ритуальным сосудом, захоронения иной пространственной ориентировки, кремация. Разнообразие элементов погребального обряда свидетельствует о сложном и продолжительном пути становления христианской погребальной обрядности. Вариативность погребального обряда представляет население древнего Владимира как общность выходцев с разных территорий, носивших различные культурные традиции.
The article highlights the funeral ceremony options of the ancient Vladimir necropolis discovered and researched during the protective archaeological excavations in 20162017 on the territory of the educational complex “The Patriarch’s garden” in Vladimir. The burial ground is located on a high promontory formed by the southern slope of the left bank of the Klyazma river and the slope of the relief depression where the garden is situated. The ancient cemetery is located on an area of at least 1000 m. Burials were located in 3 tiers. Later burials recorded in the cultural layer are made according to the christian burial ritual, it is dated by the second half of the XIII-XVth centuries. Early burials (XII-early XIIIth centuries) were made in burial pits let into the mainland. There are features of other funeral rite variants with the predominance of christian rites in these burials: burial in birch bark, burial with a ritual vessel, burial of a different spatial orientation, cremation. The variety of the funeral rite elements indicates the complex and long path of Christian funeral rites formation. The funeral rite variation represents the population of ancient Vladimir as a community of people from different territories who had different cultural traditions
Analysis for models of interaction between road passenger transport operators
Authors: Lyubimov I. I. , Yakunin N. N. , Yakunina N. V. 
Published: January 2023

Introduction. The authors consider the current models for the organization of urban passenger road transport, the structure of each of the models and their characteristics. The reason for writing the work was the poor study of the factors that determine the break-even transportation of passengers and, as a result, the construction on this basis of a system of interaction between transport authorities and transport operators. Thus, the purpose of the study is to create models of interaction between subjects and objects of passenger road transport. The working hypothesis of the study is to overcome the existing fragmentation of models through the development of additional blocks, the content of which is a scientifically based choice of models for the interaction of participants in the transport process in the system of passenger road transportation.Methods and materials. Three existing models for organising the work of passenger road transport are analysed. Their influence on the economic efficiency and safety of the transport process is considered. The prerequisites for the creation of algorithms for the transition from one model to another and for evaluating their effectiveness are determined.Results. According to the authors, this study will be useful for both the organizers of passenger road transport and carriers. From a practical point of view, this study will be useful to improve the efficiency and break-even of passenger road transport, as well as to maximize the ‘transparency’ of financial interaction between participants in this market.Conclusions. Further direction of research on this topic will be carried out in the direction of developing a methodology for switching models between themselves, i.e. when and how it is expedient to apply one or another model of passenger road transportation.
Treatment of material surfaces with bacterial solutions to initiate the deposition of calcium carbonate. Review
Authors: Ilyina L. V. , Tatski L. N. , Dyakova K. S. 
Published: January 2023

Introduction. Surface treatment plays an important role in protecting decorative stone and concrete from the effects of harmful environmental factors. To protect stone surfaces, dietary supplements in the form of carbonatogenic bacteria, the product of which is calcium carbonate, can be used.Materials and methods. The selection and analysis of publications containing the results of research and experiments, which allow to draw conclusions about the feasibility of using bacterial solutions for surface treatment, has been carried out.Conclusions. The formation of a layer of calcium carbonate on the surface of the material reduces gas permeability, reduces water absorption, increasing the durability of concrete. It was found that the surface treatment of cement stone with solutions containing cultures of urobacteria strengthens the surface layer of the stone, but does not restore its strength. It is important that the formed layer of calcium carbonate on the surface of the material does not clog its pores. The chemical and structural similarity between the processed material and the resulting carbonate compounds must be observed. The dosage of urea and calcium chloride should correspond to the number of bacterial cells, since excess components of the nutrient medium leads to their accumulation in the pores.
