Abstract.

Plugging of soil pipes can be detrimental to hillslope stability. A soil pipe commonly becomes plugged through internal erosion when the pipe wall collapses. When a pipe becomes plugged, a pressure buildup occurs upslope from the plug. This pressure may be enough to remove the plug, or the pressure may continue to build in the soil matrix, which may lead to hillslope failures. Based on field observations, it is known that both processes occur, but limited data exist to understand if and when plug removal or pressure buildup occurs or how to model these processes. This study involved well-controlled laboratory experiments to determine instantaneous pressure buildup behind soil plugs and conditions for which an idealized plug in a soil pipe will be removed. Laboratory experiments were conducted with a smooth or roughened 100 cm long clear polyvinyl chloride (PVC) pipe. A pipe plug (3 or 6 cm) was established 90 cm along the pipe length. Triplicate experiments were conducted with two pipe diameters, two soil types (sand and sandy loam), two plug lengths, three pipe roughness values, various packing densities, and with both dynamic and constant pressure heads. Digital pressure gauges were installed to monitor pressures in the pipe both before and after the plug. The upslope pressure and the length of time that the plug withstood the pressure before removal were recorded. Regardless of pressurized time, all plugs were initially mobilized as intact plugs and then in many cases quickly disaggregated. Some sandy loam plugs withstood pressures of 100 cm; more cohesive plugs could withstand much higher pressures. In addition, pressurized times exceeded 1000 s for some plug conditions even with short (3 to 6 cm) plugs. Therefore, hillslopes upslope of a plugged soil pipe may experience considerable pressure buildup for extended periods of time. Plug physical characteristics are important; for example, the plug’s bulk density had a positive exponential relationship with the pressurized time. Soil water dynamics inside the plug will need to be considered, as well as the hydraulic boundary providing inflow to the soil pipe. These experiments provided insight into the dynamics of plugged soil pipes with the eventual goal of assisting in being able to better predict internal erosion and hillslope failure. Future experiments are needed across a wider range of soil types. Keywords: Hillslope, Internal erosion, Macropore, Pipe clogging, Pipeflow, Pressure buildup, Sediment transport, Soil plug.

Abstract.

Sweet potato is a unique high-calorie food because it is an excellent source of some essential micronutrients, such as provitamin A (ß-carotene). The quality of par-fried frozen sweet potato products is impacted by several factors that have not been well researched, such as freezing rate and surface modification. In this study, our objective was to evaluate the effect of freezing rate (at -20°C, -30°C, -40°C, and -60°C), surface pretreatment including blanching and gum coating (methylcellulose, sodium alginate, or mixed gums), sample dimensions (strips or slices), and cultivar (Covington and Murasaki) on several quality attributes of fried sweet potato. Based on our study, frying at 180°C yielded the lowest oil content among the tested temperatures. Compared with Covington samples, Murasaki strips coated with mixed gums produced fried samples that were significantly (p = 0.05) lower in fat uptake (10.84%), less porous (35.5%), crispier (maximum force = 6.90 N), lighter, less red, and yellower. Higher freezing rate, 5.12°C min-1 (at -60°C), showed significantly lower fat content, and lower lightness or yellowness than lower freezing rates. Frying at 180°C significantly reduced vitamin C and ß-carotene levels from 3.75 mg and 349.27 µg per 100 g to 1.92 mg and 105.99 µg per 100 g, respectively. X-ray micro-computed tomography showed a significant decrease in porosity because of high freezing rates. The general conclusion is that faster freezing rate is better for par-fried sweet potato quality preservation. Keywords: ß-carotene, Fat uptake, Gum coating, Par-frying, Sweet potato, X-ray micro-computed tomography, Vitamin C.

Si estas paredes hablasen. El Instituto Internacional y la experiencia espacial del pasado
Authors: Callaway Nicholas Ford
Published: January 2019

Este ensayo explora un curso sobre la historia del edificio del Instituto Internacional sito en la calle Miguel Ángel, 8 en Madrid, “If these walls could speak: Reading Miguel Ángel, 8”. El curso proponía un acercamiento artístico a la historia en el que el espacio fuera el protagonista, mediante un proceso basado en, por un lado, el contacto directo con el espacio y, por otro, el estudio de fotografías antiguas, todo ello en combinación con el uso de fuentes primarias textuales. De esta manera, se buscaba ver y poner de relieve las huellas del pasado en las superficies del presente, para construir una mirada que nos ayudara a ubicarnos en el espacio y el tiempo.
Pinchar un PDF. Acercamientos al diaporama performativo
Authors: Ferreira Martín Antonio
Published: January 2019

La mayoría de lxs profesorxs universitarixs y de lxs artistas utilizan el diaporama en PDF —o cualquier otro de los numerosos softwares que ofrecen los dispositivos digitales— para acompañar sus discursos, siendo ello consecuencia del paradigma de conocimiento audiovisual contemporáneo, donde la palabra y la imagen en movimiento parecen indisolubles. Este aparataje, que suele pasar desapercibido o darse por sentado, incita a reflexionar sobre el diaporama como plataforma de significado en sí mismo. En consecuencia, propongo dirigir este soporte lowtech hacia la conferencia performativa, disciplina que hace borrosas las fronteras entre la teoría y la práctica y que puede hacer tartamudear esta coreografía del poder que es la conferencia sobre diapositivas. Los movimientos dislocados de teclas, voz, pantallas, proyecciones o ratones otorgan a la «performance de PDF» un carácter de multitarea que muestra al mismo nivel work in progress y voice in progress. Con esta estrategia, consigo que la información atraviese el cuerpo y reflexiono sobre cómo, cuánto y desde dónde se miran los archivos para paliar una creciente miopía dialéctica. En definitiva, trato de abordar desde la historia y la especulación el «Formato de Documento Portátil independiente» que me encuentro rellenando en este preciso momento.

Este artículo es un intento de introducir las prácticas de resistencia popular y local de Fidelina en la academia. Es un ensayo de situar el conocimiento desde un relato vinculado a la vida personal de quien lo escribe. De ese relato, que es el de Fidelina, se rescatan modos de hacer popular con los que se plantea una forma de imaginar colectivamente una utopía —local, situada en un contexto preciso— de las disidencias sexuales.
Hazlo tú y házselo a otrxs. Sobre públicos y colecciones en las bibliotecas
Authors: Van Tartwijk Crespo Marta , Perez Iglesias Javier
Published: January 2019

Las autoediciones han dado voz a quienes han sentido que tenían algo que decir al margen de los canales establecidos. Por eso hay una tradición en el uso de los fanzines entre comunidades queer, movimientos sociales, anarquismos, feminismos… Los artistas descubrieron hace ya mucho que un libro podía ser una pieza artística y hasta aquí hemos llegado con una producción cada vez más variada de publicaciones. Hay un encuentro entre lo autoeditado (o editado en los márgenes producciones editoriales o artísticas hegemónicas u oficiales) y la intencionalidad artística que desborda la idea tradicional de libro que ha sido paradigma en bibliotecas y librerías. Los libros ya no son lo que eran, las bibliotecas tampoco.

En el siguiente artículo expongo mi metodología de trabajo como docente de la asignatura de Taller de Proyectos de Creación Contemporánea, materia que me permite explorar, junto con los estudiantes, procesos artísticos diferentes a los normalizados en las aulas universitarias. Mi interés prioritario reside en ofrecerles herramientas para indagar sobre el territorio cotidiano y su relación con el mismo; a nivel físico, sensorial y simbólico, a fin de ampliar y desarrollar la experiencia artística como herramienta transversal hacia nuevas miradas y significantes posibilidades expresivas, que van más allá del material, formato y discurso establecidos en la academia. Para abordar estos factores utilizo el cuerpo, el espacio y los elementos que nos rodean como materia principal de investigación experiencial.
La primavera disidente. Acciones artísticas en torno a la crisis académica del 2015 #UnaNoTeCalles
Authors: Colmán Achucarro Fernando Gabriel
Published: January 2019

La Universidad Nacional de Asunción ha sido un bastión en la formación universitaria en Paraguay, siendo parte de esta el Instituto Superior de Arte fundado en 1996 por la artista y pedagoga Olga Blinder. En el año 2015 el estallido de la protesta denominada #UnaNoTeCalles ha generado una crispación que repercute hasta la actualidad, de la cual las manifestaciones críticas fueron parte. En estas acciones se entremezclan posturas políticas y sociales, de las cuales el Instituto—por una ausencia de voluntad o mera indiferencia—, no se ocupa y de la cual un número reducido de estudiantes y profesores han protestado, embanderado una causa que creían justa: la reforma e innovación dentro de la misma.

El artículo analiza las razones por las que una educación artística dentro de los canales oficiales resulta insuficiente para la formación de agentes verdaderamente eficaces en el panorama del arte contemporáneo. A partir de este análisis, el texto se centra en aquello que una educación paralela necesita ofrecer para compensar las carencias mencionadas, y sugiere maneras de hacerlo posible. En esencia, la educación no reglada necesita generar posiciones en contra. Esto es, estimular la generación de organismos auto-educativos que existan como negación de lo que se les ha sido propuesto.

Tres escalas de aproximación urbana: fuera de los mapas, plazas en ‘transición’ y umbrales hacia lo privado
Authors: Martínez Medina Andrés
Published: January 2019

Se trata de la reseña de tres libros que se expone siguiendo un alógica de disminución dela escala de aproximación a los fenómenos urbanos y arquitectónicos. El primer libro reseñado, "Fuera del mapa" (2017), trata sobre lugares del mundo que se deslizan entre geografías físicas y virtuales, con ciudades o asentamientos urbanos que cuestionan sus conceptios clásicos. El segundo libro, "Transformación del espacio público de Alicante (1975-1995)", (2016) estudia la evolución de los espacios urbanos de esta ciudad -las plazas- en el perido de la Transiciñon española con el protagonismo y rol para la recuperación de la convivencia y la interacción social. Y el tercero de los libros, "Volte stellari e planteriane negli atri barocchi in Torino" (2017), analiza el caso de los complejos zaguanes de los inmuebles nobiliarios y burgueses del barroco de Turín, con sus extraordinarias geometrías, como umbrales de transición desde el espacio exterior público hacia los interiores residenciales privados, mediante levantamientos gráficos actuales apoyados en una amplia investigación histórica.

Aim: This study aimed to assess the level of awareness of rural poultry farmers on vaccination and to detect Newcastle disease virus (NDV) antibody in local birds (LB) and eggs in Kwara State, Nigeria.

Materials and Methods: Data on farmers' attitude, knowledge, practices, and experiences on ND mortality were obtained through an interview using a structured cross-sectional checklist. NDV antibodies were detected in sera and egg yolks of local chickens (LC) and guinea fowls (GF) using hemagglutination inhibition test.

Results: A total of 83 interviewees, 287 sera and 121 egg yolk extracts, were examined. The study revealed that 98.8% (82/83) of the interviewee had never vaccinated their flock before. 90% of the interviewee had reported high mortality in birds within 1-6 months old, while the major clinical signs were cold (40.4%) and torticollis (30.8%). Evidences of LB exposure to wild-type NDV were confirmed by the detection of NDV antibodies in 20.8% and 0% of LC and GF, respectively. The mortality differences experienced in <1 and 1-6 months old LB could be explained by the presence of maternally-derived NDV antibody (49.6%) in egg yolk.

Conclusion: The study showed that LB suffers from NDV as a result of LB keepers' ignorance and neglect by the government. This has limited local investment and subsequent contribution to gross domestic product. This study suggests that the key factors to the prevention of ND remain awareness creation about poultry vaccination, production of affordable vaccines, and availability/accessibility to veterinarian (or trained personnel).

Aim: The aim of the current study was to evaluate the efficacy of a trivalent-inactivated oil-emulsion vaccine against challenge by different clades highly pathogenic avian influenza (HPAI) viruses including HPAI-H5N8 and the virulent genotype VII Newcastle disease virus (NDV) (vNDV).

Materials and Methods: The vaccine studied herein is composed of reassortant AI viruses rgA/Chicken/Egypt/ ME1010/2016 (clade 2.2.1.1), H5N1 rgA/Chicken/Egypt/RG-173CAL/2017 (clade 2.2.1.2), and "NDV" (LaSota NDV/ CK/Egypt/11478AF/11); all used at a concentration of 108 EID50/bird and mixed with Montanide-ISA70 oil adjuvant. Two-week-old specific pathogen free (SPF) chickens were immunized subcutaneously with 0.5 ml of the vaccine, and hemagglutination inhibition (HI) antibody titers were monitored weekly. The intranasal challenge was conducted 4 weeks post-vaccination (PV) using 106 EID50/0.1 ml of the different virulent HPAI-H5N1 viruses representing clades 2.2.1, 2.2.1.1, 2.2.1.2, 2.3.4.4b-H5N8, and the vNDV.

Results: The vaccine induced HI antibody titers of >6log2 against both H5N1 and NDV viruses at 2 weeks PV. Clinical protection against all HPAI H5N1 viruses and vNDV was 100%, except for HPAI H5N1 clade-2.2.1 and HPAI H5N8 clade- 2.3.4.4b viruses that showed 93.3% protection. Challenged SPF chickens showed significant decreases in the virus shedding titers up to <3log10 compared to challenge control chickens. No virus shedding was detected 6 "days post-challenge" in all vaccinated challenged groups.

Conclusion: Our results indicate that the trivalent H5ND vaccine provides significant clinical protection against different clades of the HPAI viruses including the newly emerging H5N8 HPAI virus. Availability of such potent multivalent oil-emulsion vaccine offers an effective tool against HPAI control in endemic countries and promises simpler vaccination programs.

Published: January 2019

Gen Insulin-like Growth Factor 1 (IGF1) pada mamalia berfungsi untuk mengontrol pertumbuhan tulang dan otot. Oleh karena itu gen IGF1 banyak digunakan sebagai salah satu kandidat gen untuk seleksi ternak. Penelitian ini bertujuan untuk mengidentifikasi genotip gen IGF1 (ekson 1) menggunakan metode PCR-RFLP dengan enzim restriksi SnaBI (TAC*GTA). Sebanyak 90 ekor sampel DNA sapi Pasundan dari Kabupaten Ciamis dan Pangandaran, Jawa Barat telah digunakan pada penelitian ini. Hasil penelitian ini menunjukkan bahwa seluruh sampel yang dianalisis memiliki genotip CC dengan alel C sebagai alel yang umum pada gen IGF1/SnaBI. Genotip CC yang diperoleh pada penelitan ini disebabkan karena terdapat mutasi transisi pada posisi basa ke g.218T/C (GenBank: KF202095). Mutasi ini menyebabkan perubahan asam amino dari methionine (AUG) menjadi valine (GUG). Disimpulkan bahwa gen IGF1/SnaBI pada sapi Pasundan bersifat monomorfis dan tidak dapat digunakan untuk seleksi molekuler.

Published: January 2019

The aim. To assess food dyes (FD) effect on the immediate and delayed blood cells cytokines secretion in allergic patients. Materials and methods. The study involved 38 people with allergic asthma combined with allergic rhinitis, the average age - 37 [31; 43] years. 28 people (74%) reported food intolerance, 25 (66%) - FD intolerance; 13 - did not report reactions to the FD in anamnesis - the group of comparison. Cytokine secretion was determined after 3 and 24 hours blood incubation with a mixture of 0.01% and 0.001% FD solutions – Tartrazine (E102), Сarmuazine (E122), Ponce (E124), Sunset (E110) and Titanium dioxide (E171). The FD solutions concentrations (0.001% and 0.01%) consistent with the norms of acceptable daily intake in humans. The levels of IL-1β, IFN-γ, IL-17, IL-6 were determined in the supernatant using standard ELISA test systems. Results. 3-hour incubation of whole blood with 0.001% solution of five FD mixture in 100% and with 0.01% solution - in 42% cases stimulated secretion of IL-17, compared with 0,9% NaCl. FD solutions more often inhibited (58%) than stimulated (17%) immediate secretion of IL-1β and IL-6, compared to 0,9% NaCl; in equal amounts inhibited and stimulated secretion of IFN-γ (33%) in both concentrations. A mixture of FD stimulated secretion of IFN-γ stronger, than Con A at 0.001% concentration - in 4 (50%) cases, in 0.01% concentration - in 3 (37.5%) cases. Patients with a FD allergy observed for immediate inhibition of IL-1β, unlike similar samples in the control group. Stimulation of IL-17 secretion by 0.001% FD solution in comparison with 0,9% NaCl was observed in both groups. After 24-hour blood incubation with 0.001% tartrazine (T) solution secretion of IL-17 increased in 80%; with 0.01% solution - in 50%; both concentrations inhibited the secretion of IL-6 (50%). 0.001% and 0.01% T solutions more often inhibited than stimulated secretion of IL-1β (27% vs. 8%) and secretion of IFN-γ (in 46-54% vs. 8%, respectively) compared with 0,9% NaCl. Patients with FD allergy were observed for significant increasing secretion of IL-17 and decreasing secretion of IL-1β, IFN-γ, IL-6 after 24 hour incubation with 0.001% T solution, in comparison with 0,9% NaCl, the group without FD anamnesis - 0.01 % T solution more often inhibited IFN-γ, than physiological solution. Con A after 3 and 24 hours incubation caused stronger secretion of IL-1β, IL-17, IL-6, than the FD solutions. Conclusions. FD in hygienically permissible doses have immediate and delayed effects on the blood cells. They cause the secretion of IL-17 involved in allergic inflammation, inhibit the release of cytokines IL-6 and IFN-γ and immunomodulate the immediate secretion of IL-1β.

Microbiocenosis of the mucous membranes is a very sensitive indicator that responds with quantitative and qualitative changes to any changes of external and internal environment of the body. The mucous membranes of open cavities of the body function as a single organ, and therefore independently from the mucous biotope simultaneously similar changes are registered (same types- degrees) of their microbiocenoses; the localization of the pathological process in the particular biotope of the mucous determines the severity of changes in microbiocenosis, compared to other biotopes of the mucous membranes of the body. It is established that in good health and absence of clinical manifestations on the mucous membranes of open cavities of the macroorganism (as a single functional unit - the organ) type I (degree) microbiotope or type II (degree) microbiotope of mucous membranes is registered; in the prodromal period of an infectious disease type III (degree) of microbiotope or type IV (degree) of microbiotope of mucous membranes is registered. During health disturbance (disease) and clinical manifestations of infectious disease with a favorable course III type (degree) of mucous microbiotope IV or type (degree) of microbiotope is registered; I type (degree) of mucous membranes microbiotope II or type (degree) of mucous membranes microbiotope registration (unfavorable course of the process) indicates the inhibition of anti-infective drug resistance and chronic disease; with the recovery, subsidence of clinical signs and eradication of the pathogen revealed I type (degree) or II type (degree) of mucous microbiotope (a favorable process), and the clinical manifestations (adverse the infectious process)- chronization, detection of type III (degree) of microbiotope or type IV (degree) of mucous microbiotope indicates the need for further treatment.

Published: January 2019

It is common knowledge that there are patients who have an uncomplicated cataract surgery with an actual improvement of their visual acuity, but they are dissatisfied with their final visual capacity. It is hypothesized that patients’ preoperative expectations play a significant role in their postoperative perceptions. A systematic review of the recent literature regarding preoperative expectations of patients before lens extraction surgery and their postoperative perceptions as regards the visual outcome was performed based on the PubMed, Medline, Google Scholar, American Academy of Ophthalmology, Nature and Springer databases in September 2017 and data from 14 descriptive and 7 comparative studies were included in this narrative review. The objective of this review is the determination of the relationship between preoperative expectations and postoperative perception of visual outcome, as well as the investigation of predictors of patient satisfaction by understanding the factors that determine preoperative patient expectations. A considerable number of studies evaluate patient expectations before cataract surgery and compare them with postoperative patient perceptions. In conclusion, the final patient’s postoperative perception could be affected both by the actual outcome of the operation and by patient preoperative expectations. Ocular and systemic comorbidity, unrealistic expectations, preoperative spectacle independence, the cost of surgery, and a previous cataract surgery as well as the level of health literacy and age could influence preoperative expectations and predict more accurately patient satisfaction. Taking these factors into consideration could allow surgeons to control the expectations with an extensive preoperative counseling.
Histological Features of Oral Cavity Mucous Membrane Epithelium in Six-Month-Old Experimental Animals Born with Macrosomia

Published: January 2019

We examined the histological features of the mucobuccal fold of oral cavity mucous membrane from the area of the masticatory teeth roots’ projection in 6-month-old Wistar Albino Glaxo rats with fetal macrosomia. The animals were divided into groups according to the body weight, the body length, and the Quetelet index at birth. A morphological study was performed using the Leica SP8 AOBS laser scanning confocal microscope and a conventional light (Axiostar, Zeiss) microscopy. Morphometric parameters were used to estimate the degree of acanthosis development in the epithelium of the oral mucosa, which indicates the intensity of its proliferation. Numerous narrow and deep acanthotic outgrowths and densely located ‘juvenile’ epitheliocytes in the basal layer on the apex of the acanthotic protrusions were found in animals with fetal macrosomia that was due to intrauterine obesity. In these animals, the morphometric index, which we used, was maximally different from that in the control group. In animals with fetal macrosomia that was due to intrauterine growth acceleration of the body, the hyperproliferation of the mucous membrane epithelium of the oral cavity was absent or little pronounced. It can be assumed that fetal macrocosmia with obesity causes instability in the epithelium of the oral cavity mucosa, its rapid death, and therefore, a more active stimulation of proliferation.

Published: January 2019

Background/Aim: Primary hepatic leiomyosarcoma is an extremely rare type of liver sarcoma with relatively poor prognosis, with about 50 cases having been reported in the literature. Potential origins of this tumor in the liver are the smooth muscle cells in the round ligament, intrahepatic blood vessels and intrahepatic bile ducts. There is no apparent sex predilection and there is a wide age range. The clinical presentation is not specific and the diagnosis depends on the expression of markers such as smooth muscle actin, desmin and vimentin by tumor cells. Patients and Methods: Herein, we present a case of a bulky primary hepatic leiomyosarcoma in a 68-year-old female patient. The patient underwent resection of the exophytic mass en block with the hepatic segments III and IVB. Conclusion: Surgical resection is the most effective among the treatment options.

It is a little bit curious, that at the end of the Late Bronze Age and the Early or Pre-Roman Iron Age these temple ornaments were the most common metal ornament type in the territory of Latvia, but later periods these ornaments almost disappeared.The Pre-Roman Iron Age temple ornaments can be divided into three groups. The most wide-spread temple ornaments were plain spiral temple ornaments (first group) and ornaments with a spiral middle part and spoon-shaped ends (second group). The third group consists of ornaments made of thin bronze wire rings with beads and pendants.

Archaeological evidence on the culture of the population of North-Western Russia in the period of Roman influences is extremely scarce (Кулешов, 2005; Juškova, 2006). An exception is the new group of sites of the culture of stone burial grounds with fences (Tarandgräberkultur) recently revealed in the South-West of Leningrad Oblast. The main area of this culture lies throughout what is now Estonia and northern Latvia. It is represented mostly by burial grounds while the settlement-sites are rare. The cemeteries contain collective burials both with inhumations and creations. The burials are arranged in one or several rows and are encircled by small rectangular stone fences attached to each other. The skeletal remains are found as a rule among layers of stones and limestone chips together with the grave offerings: bronze ornaments (fibulae, rings, bracelets, neck rings), beads, iron utensils (knives, grass cutters, awls) and occasionally weapons (spear and dart heads, shield-bosses).

Korespondencinė analizė kaip chronologinis metodas
Authors: Kačkutė Rūta
Published: January 2019

Šiame straipsnyje bus kalbama apie korespondencinę analizę (angl. correspondent analyses) – archeologijos moksle taikomą tyrimą, kuris yra pagrįstas seriacijos metodu. Pažodinis termino „correspondent analyses“ vertimas į lietuvių kalbą būtų „atitikties tyrimas“, tačiau, nesant nusistovėjusios lietuviškos terminijos, ir siekdama aiškumo pasirinkau terminą, kuris asocijuojasi su angliškuoju....USE OF THE CORRESPONDENCE ANALYSIS IN ARCHEOLOGYRūta KačkutėSummaryAbstract. This article aims at introducing correspondence analysis, the technique applied in the science of archaeology, and at showing how it can be used in chronological research. Correspondence analysis rests upon the seriation method that has been in use by the archaeological scientists since the late 19th century. The seriation method basically draws upon the theoretical statement that the development of material culture is of a continuous character and guided by fashion and/or functionally-determined mechanisms that make the repetition of the elements follow a double-lens-shaped road over time (Madsen, 1989 a, p. 10). There are several ways of doing seriation. Correspondence analysis is one of the techniques successfully applied in archaeological research. The technique was developed in France and broadly recognised by Scandinavian archaeologists, but still not very much in use by archaeologist in the Baltic States. The article illustrates the use of correspondence analysis for detecting chronology of Early Roman Iron Age graveyard ceramics. The correspondence analysis performed rests on KVARK, the software developed by T. Madsen. The article explains how this program works and how convenient it is for chronological and social studies....

Pentinų radiniai pietrytiniame Baltijos regione romėniškuoju ir tautų kraustymosi laikotarpiu – keletas pastabų
Authors: Smółka Emilia
Published: January 2019

There were two dominating cultures developing on the south-east coast of the Baltic Sea in the Roman Iron Age, namely the Wielbark and Balt cultures. The former developed as a result of the migration of Goths into territories which in the Pre-Roman Iron Age had been occupied by the Oksywie communities. The lat­ter, on the other hand, continued traditions which had already been present in the area. Cultural transforma­tions in Central Europe at the turn of the eras put these two populations under influence of the early Roman Iron Age stylistics of North-Central Europe (see also Wołągiewicz, 1981, p. 165).

Pietinis Baltijos pakraštys ir vidaus sritys. Išskirtinės problemos
Authors: Błażejewski Artur
Published: January 2019

In the studies on the Baltic Sea region in the Roman period a prominent role play works concerning con­tacts between the south Baltic coast and areas situated more to the south. Previous publications generally dealt with two main aspects of these contacts. The first one was focused on the problem of rela­tions of the Baltic coast with the south along the amber route. Of course, the researcher of outstanding merit was here Jerzy Wielowiejski, the author of many valu­able publications whose findings are mostly still valid (1970; 1980). Their value lies primarily in discuss­ing the nature of trade between ‘peoples of the north’ on the one hand, and Roman provinces, particularly the Danube ones, and Italia on the other hand. To the works of J. Wielowiejski publications of other authors also referred. [...]

Погребальные древности юго-восточной Балтии различных исторических эпох изучаются немецки­ми археологами уже почти три столетия. Правда, систематизирование этого объёма информации как тафологического материала фактически не проводи­лось. Как показывают разработки М. В. Доброволь­ской, для адекватного анализа погребального обря­да, прежде всего – для сложных для обработки тру­посожжений необходим максимально подробный сбор информации по каждому комплексу. Только на основании этого может быть сформирована «мето­дика реконструкции событий, приведших к возник­новению тех или иных объектов, подвергнувшихся воздействию огня…» (Добровольская, 2010, с. 85).

Egodokumentai Lietuvos Didžiosios Kunigaikštystės politinės kultūros tyrimuose: Jano Cedrowskio dienoraščio atvejis
Authors: Petrauskė Kristina
Published: January 2019

[straipsnis ir santrauka lietuvių kalba; santrauka anglų kalba]

Egodokumentiniai tyrimai nuolat populiarėja ir vis plačiau taikomi is­toriografijoje. Nors už egodokumentų sąvokos slypintys šaltinių tipai – dienoraščiai, atsiminimai, autobiografijos ir daugelis kitų smulkesnių žanrų – jau seniai naudojami istoriografijoje, tačiau daugybę metų pir­minė jų funkcija buvo pildyti ir plėsti faktologinę žinių bazę, kadangi į galimą subjektyvumą, neretai ir į fikcinius elementus šiuose šaltiniuose buvo žiūrima itin atsargiai. Naudojant egodokumentinį tyrimo metodą subjektyvūs ir fikciniai elementai šaltiniuose gali daugiausia papasako­ti apie autoriaus pasaulėjautą. Pasitelkus LDK bajoro Jano Cedrowskio atsiminimus, galima pabandyti praktiškai patikrinti, ar LDK bajorų ego­dokumentai gali liudyti politinę jų kultūrą. Šie atsiminimai itin trum­pi, tačiau labai vaizdingi. Juose atsispindi ne tik asmeninio jo gyvenimo momentai: jaunystės kelionės, su šeimos pagausėjimu susijęs džiaugsmas ar netekties sąlygotas skausmas, bet ir viešo jo gyvenimo detalės, kurios atspindi politines rašiusiojo pažiūras ir iš tam tikrų veiksmų išryškėjusią politinę kultūrą.
Autocenzūros galia: Merkinės seniūno Antano Kazimiero Sapiegos 1722–1733 m. užrašai
Authors: Sarcevičienė Jolita
Published: January 2019

[straipsnis ir santrauka lietuvių kalba; santrauka anglų kalba]

Straipsnio centre – 1722–1733 m. Merkinės seniūno Antano Kazimie­ro Sapiegos kasdienės veiklos dienoraštis, kuriame fiksuojami susitikimai, korespondencija, valdų administravimo klausimai, autoriaus sveikatos būklė, kelionių maršrutai, LDK tribunole nagrinėtos bylos, kiti įvairūs veiklos faktai. Jame nerasime refleksinio pobūdžio minčių, aiškiai jaučia­ma emocinė autoriaus distancija nuo aprašomų įvykių. A. K. Sapiegos gyvenimo ritmą lėmė ne tik ūkiniai reikalai, bet ir valstybės institucijų – Tribunolo, seimelių, Seimo – darbo sesijos. Susipažinus su dienoraštyje užfiksuotos informacijos temomis, keliama prielaida apie autocenzūrą, turėjusią įtaką fiksuojamos informacijos pasirinkimui. Todėl straipsnio tikslas – pristatyti šaltinio įrašų temas, aptarti informacinį bei parene­tinį jų pobūdį ir taip išryškinti kai kuriuos aspektus, kurie galėtų paliu­dyti, kad autorius atsirinkdavo dienoraštyje pateikiamą informaciją, ir atskleisti autocenzūros įtaką rašant dienoraštį. Autorius sąmoningai at­skyrė ne tik žemvaldžio gyvenimą nuo politiko gyvenimo, bet ir viešojo bei privataus asmens gyvenimus. Orientuodamasis į būsimus skaitytojus, A. K. Sapiega cenzūravo užrašus, susikoncentravo į tuos įvykius, kurie turėjo ar galėjo suformuoti teigiamą jo įvaizdį paveldėtojų akyse. Nors šaltinis ir atskleidžia įvairialypius Merkinės seniūno kasdienio gyvenimo epizodus, jame brėžiami migloti autoriaus asmenybės kontūrai.
Rašytojos Žemaitės (meninė) gyvenimo rekonstrukcija remiantis archyvalijomis

[straipsnis ir santrauka lietuvių kalba; santrauka anglų kalba]

Julijos Žymantienės-Žemaitės (1845–1921) privačiosios raštijos ir egodoku­mentų išliko gana daug. Paminėtina autobiografija, apimanti laikotarpį iki kūrybinio kelio pradžios 1892 metais, kurioje atsiskleidžia bajoriška tėvų kilmė, pirmi rašytojos mokslai, šeimyninio gyvenimo sunkumai, troš­kimas šviestis. Vėliau Žemaitės gyvenimą padeda atkurti autobiografi­niai pasakojimai „Pasiklausymai“, „Iš mano atsiminimų“, „Iš baudžiavos laikų“, „Pirmieji mano žingsniai“, „Kalėjime“, taip pat rašinys „Povilas Višinskis“ (1916 m.), kuriame prisimenami pirmieji kūrybiniai žingsniai. Kaip atskirą egodokumentų grupę galima išskirti Žemaitės laiškus spaudos darbuotojui, literatūros kritikui Povilui Višinskiui (1875–1906, išliko dau­giau nei 70 laiškų), taip pat artimam bičiuliui Konstantinui Petrauskui (1878–1947, išliko daugiau kaip 60 laiškų). Laiškuose P. Višinskiui ryškėja kūrybos vingiai, abejonės, asmenybės formavimasis, laukiama kūrybos mėginimų kritikos ar pritarimo tam. O štai svarbiausia laiškų K. Petraus­kui tema yra meilė, atskleidžianti šio vėlyvo rašytojos jausmo gyvybingu­mą, suteikianti asmenybei ypatingų spalvų ir bruožų. Be to, laiškai plačiai atveria 1911–1915 metų politinio ir kultūrinio Vilniaus gyvenimo foną.

Straipsnyje nagrinėjami Panevėžio apskrities Krekenavos miestelyje 1920–1945 metais gyvenusio ir dirbusio fotografo Tado Bajorūno už­rašai – paprasta užrašų knygelė, kurioje surašytos jo 1934–1941 metais gautos pajamos. Atlikę atvejo studiją – išanalizavę šiuos užrašus, galime sužinoti, ar tuo laikotarpiu fotografija mažame miestelyje buvo pelnin­gas verslas ir kokia veikla, neskaitant fotografijos, fotografas dar užsiėmė, kiek daugiausia pajamų gavo ir už kokią veiklą. Apibendrinę rezultatus ir pasitelkę duomenis, atspindinčius kitų Lietuvos regionuose aptaria­muoju laikotarpiu dirbusių fotografų veiklą, galėsime susidaryti bendrą jų ekonominės situacijos vaizdą.

Šiaulių apskrities Povilo Višinskio viešosios bibliotekos darbuotojų egodokumentai: atsiminimai iš tremties, dienoraščiai
Authors: Baškienė Audronė
Published: January 2019

[straipsnis ir santrauka lietuvių kalba; santrauka anglų kalba]

Straipsnyje nagrinėjami bibliotekos rankraščių fonde saugomi darbuotojų, gimusių tremtyje ar išgyvenusių tremtį, atsiminimai bei dienoraščiai. Bibliotekininkė Nijolia Kasparavičienė buvusių politinių kalinių ir tremtinių, dirbančių bibliotekoje, atsiminimus sudėjo į kraštotyros darbą „Ilgi tremties metai“ (1991). Užrašyti dešimties darbuotojų atsiminimai, kurie papildyti nuotraukomis ir dokumentais. 1991 m. ir 1992 m. tremtiniai organizavo ekspedicijas į Kazachstaną ir Sibirą. Taip atsirado du dienoraščiai „Antroji ekspedicija į Karlagą“ (1991 rugpjūčio 9–19 d.) ir „Po Sibiro platybes“ (1992 rugpjūčio 4–22 d.). Įspūdžius dienoraščio forma užrašė bibliotekininkė, tremtinių dukra Nijolia Kasparavičienė. Pagrindinė mintis atsiminimuose – asmeninis likimas siejamas su Lietuvos likimu. Dienoraščiuose fiksuojamos aplankytos vietos, minimi sutikti žmonės, perteikiamas jų požiūris į praeitį, nuomonė apie nepriklausomos Lietuvos ateitį. Dienoraščių autorė nesinaudojo jokia literatūra, istorine medžiaga. Tai padieniui užfiksuoti faktai ir asmeniniai išgyvenimai.
