Field survey was carried out to collect soil and water samples of thirty-five numbers representing in and around the factory area covering Mandaraikadu, Devanapuram, P. Thekkampatti, C. Thekkampatti, C. Kandiyur and R. Rajapuram villages. Five hundred grams of soil samples were collected once in three months from September 2000 to September 2001 to assess the changes in soil quality parameters if any due to effluent contamination. One litre volume of water sample was collected at monthly intervals from October 2000 to September 2001 to monitor the changes in the ground water quality due to effluent discharge for crop production. The qualities of groundwater samples from different locations were compared with samples collected near intake river water (control) where the possibility of ground water pollution due to paper mill effluent was remote. The soil was analyzed for its chemical properties viz., pH, EC, OC, Available NPK, Exchangeable Na and SAR. The pH, EC, OC, available nutrients (NPK), exchangeable Na and SAR were high in effluent irrigated soils in and around the factory regions compared to the Bhavani river water irrigated soils. The above soil properties increased due to continuous effluent irrigation at periodical intervals of analysis. Observation wells in and around the factory region had high pH than that of Bhavani river water. The EC, chloride, sulphate and sodium were high in the effluent irrigated area. The BOD in the well water samples varied from 7.7 to 8.9 mg L whereas river water recorded the BOD ranged from 6.2 to 7.2 mg L'. The COD of the well water samples were also high in effluent irrigated area (67 to III mg L'). The potential salinity was lesser than 6 e mol L and the SAR was below 2.

Field experiment was conducted during 1998-2000 on soil deficient in available boron (0.35 mg) kg') at Agricultural Research Station, Bhavanisagar to study the comparative efficacy of Agribor as a source of boron on dry matter production, yield attributes and yield of maize crop. Four levels of boron (0.5, 1.0, 1.5, 2.0 kg B ha) including foliar spray of 0.2% and 0.3% through two sources viz., borax (soil) and boric acid (foliar) [S,] and Agribor [S] were tried. A significant response was obtained to B application on dry matter production, yield attributes and yield of maize at the level of 2kg B ha' followed by 1.5 kg B ha'. Foliar application also significantly increased the yield of maize over control. On comparing the sources of boron, Agribor was found to be effective in influencing the yield of maize.

AGRICULTURAL CO-OPERATION WITH SPECIAL REFERENCE+ TO WEST COAST.
Authors:   Asst.Directore of Agriculture,Tellicherry, K UNNIKRISHNA MENON
Published: August 2023

The word co-operation means working to-gether. When it concerns agriculture as a business, it should plainly enough mean the working together of farmers. The necessity for the same arises out of the one fact that the large majority of farmers in this country manage small areas. The absence of sufficient capital to work even these small holdings places the farmer within the clutches of an usuricus money or grain lender. Thus even if the crops are moderately paying the farmer's resources remain en- cumbered as he cannot meet the unusually high demand on them.

The sword-bean (Tam. Thambattankai, Coliavarakai or Val- avarakai) is common throughout India being cultivated in gardens or round about the dwellings. It is supposed to be a native of India and several varieties exist. Many wild forms are met with some of which are held to be poisnous. Climbing and bush forms are found. The climbers are allowed to trail over trellis frames or over the roofs. The plant flowers mainly from August to October but many cases have been observed where flowering takes place even as late as March or April.

In many varieties or types of paddy, the different parts of the plant above ground are usually green, but in some, a kind of purple pigment occurs in certain parts of the stem, leaf and flower. The part or parts in which the pigment exists vary in different varieties or types though, in some cases the presence of pigment in one part is correlated with its presence in certain other part or parts also. The intensity of the pigment also varies considerably.

is common knowledge that insects and several other mem-- bers of the animal kingdom cause ravages on our crops. Drought, floods, extremes of temperature, heavy winds, excessive rain, improper drainage, toxins in the soil and a variety of unexplained for partially explained causes are also known to take their toll of crop plants. Besides the above, crop plants are subject to several diseases caused by parasitic fungi. Fungi are members of the vegetable kingdom representing a low order of creation, and are ordinarily too small to be visible to the naked eye but they could be made visible with the aid of a microscope.

What is our goal? Many say it is happiness. But none can define what happiness is. This seems very strange, although the reason is clear. They crave for the ephemeral pleasures of the body. These are limited, mo- mentary. The labourer is worried about the bread for the morrow The student is anxious about his examination. The politician is annoyed by the tactics of his opponents. Similarly there is none who is not care worn about some little thing or other. But there are some who are really happy and their happiness is absolute. Who can these be? They are those who have adopted "sacrifice and service as the only royal road to happiness and not marriage and mammonism unlike those who wish for the "happiness" of the body.
The Reform in Indian Land Tenure
Authors:   Tamil Nadu Agricultural University Coimbatore  641 003 Tamilnadu, MUKERJEE RADHA KAMAL
Published: August 2023

The present distribution of land in India is fraught with great economic and social danger. Throughout India the ancient custom and tradition laid down that the cultivator had a right to retain his holding so long as he paid a definite share of the harvest or the tax demandable from him. In Southern India, where most of the land is held by petty occupiers direct from the State, this custom has been respected from the beginning of the British rule. In the ryotwari areas in Madras the registered occupant of each field is entitled to hold the land for ever, so long as he pays his land revenue; and inheritance, transfer, mortga ges, sale and lease are without restriction. Similarly in Bombay, as in Madras, a ryot is secure in possession of his holding, so long as he regularly pays the instalments of his land revenue and the right of occupancy, in the case of the ordinary survey tenure, is transferable by inheritance, sale, gift or mortgage without restriction.
Growth of Seedlings in Light and in Darkness in Relation to Available Nitrogen and Carbon
Authors:   Tamil Nadu Agricultural University Coimbatore  641 003 Tamilnadu, E MARY REID
Published: August 2023

Growth of the seedling is in- fluenced by the nature and relative amounts of the food reserves of the seed, as well as by differences in the external environment such as light and darkness, and the presence and absence of nitrates in the nutrient solntion. When the seedlings are grown without nitrogen from an outside source the following responses have been found: (a) Seeds having a high nitrogen and relatively lowcarbon content produce seedlings with a large top in proportion to the roots. (b) Seeds having a low nitrogen and high carbon content) produce seedlings with a relatively small top in proportion to the size and weight of the roots. (c) Seeds intermediate in the proportions of their reserves of carbon and nitrogen produce seedlings with intermediate proportions of shoots to roots.

Australia is in marked contrast to India as regards her agricultural problems and practices. One of Australia's great farming disadvantages is drought and insufficient rainfall. There has not been a satisfactory general rain for five years. Wing Commander L. J. Wackett who flew across the Continent recently, lecturing before the Sydney branch of the Royal Empire Society said: We hear much from time to time about the great open spaces of Australia. Having seen them from the air I regret to say they left an impression of despair. Such country can never support modern civilisation and most of it is useless waste."

Published: August 2023

O objetivo deste estudo foi investigar a relação das infestações por Monogenea com os níveis de metais traço na criação de tambaqui (Colossoma macropomum). Para isso, foram selecionadas três pisciculturas comerciais que praticam, em paralelo, produção agrícola. Juvenis de tambaqui (n = 10 por piscicultura; total = 30 peixes) naturalmente parasitados por Monogenea, foram eutanasiados por secção medular, e arcos branquiais foram excisados para análises parasitológicas. Amostras de tecido muscular e da água dos viveiros também foram coletadas para determinação dos níveis de metais traço. As concentrações de metais pesados foram determinadas por espectrometria de emissão óptica com plasma indutivamente acoplado (ICP-OES). A prevalência de parasitos Monogenea nas brânquias de tambaqui foi de 100% com intensidade média variando entre 1765,60 a 6962,37, parasitos por peixe. Entretanto, embora sejam observados altos índices parasitários em tambaquis, o parasitismo não influenciou negativamente sobre o desempenho dos peixes, uma vez que o fator de condição se mostrou isométrico e linear. As concentrações de Zn, Fe, Cr e Mg no músculo de tambaquis foram superiores ao recomendado pela legislação brasileira, considerando o consumo diário para adultos. Na água dos viveiros foram detectados a presença dos seguintes elementos: Cr, Mn, Zn, Fe, Na, Mg, Ca, K e Cu. Os maiores valores dos fatores de bioacumulação foram observados para os metais K, Zn e Na com concentrações até 72,94, 22,80 e 4,79 vezes maiores na musculatura dos tambaquis quando comparados a água dos viveiros. Logo, nossos resultados destacam que o parasitismo por monogenea não impactou negativamente a performance produtiva dos peixes, e este fato pode estar associado às boas práticas de manejo e manutenção dos parâmetros de qualidade de água. Além disso, os níveis de metais traço encontrados na musculatura dos peixes não os afetou negativamente, o que destaca o potencial papel como organismo bioindicador de qualidade ambiental.

Esse capítulo apresenta resultados preliminares do primeiro monitoramento do protozooplâncton na água de viveiros de piscicultura no estado de Rondônia. O objetivo do estudo foi documentar a composição, a abundância e a densidade de protozoários de vida livre na água de viveiros de piscicultura e verificar a possibilidade de utilização desses organismos como bioindicadores da qualidade da água. O estudo foi desenvolvido em 20 pisciculturas e foram realizadas coletas amostrais nas duas estações hidrológicas, chuvosa (meses de setembro/2021 a abril/2022) e seca (meses de maio a agosto/2022). Para a composição das amostras qualitativas, foram realizados arrastos horizontais e verticais na superfície da água dos viveiros, enquanto cada amostra quantitativa foi obtida em rede de plâncton (malha de 50 µm). A abundância e a densidade dos protozoários foram apresentadas em (Ind mL-1). Foram encontrados protozoários de vida livre na água de 55% (11/20) das pisciculturas. Foram identificadas 8 espécies de protozoários todas do filo Ciliophora, sendo elas: Paraenchelys terrícola, Apospathidium terrícola, Spirostomum teres, Linostomella vorticella, Halteria grandinella, Sphaerophrya magna, Paramecium bursaria e P. caudata. As espécies com maior abundância foram P. terricola (106,26 Ind mL-1 na estação chuvosa e 105,09 Ind mL-1 na estação seca) e A. terrícola (82,15 Ind mL-1 na estação chuvosa e 85,63 Ind mL-1 na estação seca). Este estudo representa um levantamento preliminar do protozooplâncton em viveiros de piscicultura, sendo uma importante contribuição para o conhecimento da diversidade e distribuição de protozoários de vida livre. Embora os resultados obtidos não mostrem grande diferenciação de abundância entre os pontos amostrais, os protozoários de vida livre representam importantes ferramentas para análise de ambientes afetados por diferentes graus de poluição. No entanto, haverá continuidade nos estudos sobre a dinâmica e distribuição das comunidades de microrganismos aquáticos para ampliar o conhecimento da diversidade taxonômica e ecologia das espécies, principalmente em ambientes impactados.

Neste capítulo serão descritos experimentos utilizando o cromo trivalente oriundo de diferentes fontes, pela avaliação de seus efeitos tóxicos e de sua interferência em variáveis zootécnicas e na resposta imune induzida experimentalmente em peixes de interesse comercial. O cromo é um mineral-traço essencial presente em diminutas proporções em alguns alimentos, tendo efeito sobre o metabolismo dos animais devido ao aumento da sensibilidade à insulina coatuando com ela, melhorando a tolerância à glicose, influenciando o metabolismo proteico com melhora nos índices zootécnicos. Além disso, observa-se que a suplementação em peixes, induz uma redução da cortisolemia que favorecem a imunidade, verificado pela melhora da resposta imunológica e na sobrevivência dos peixes. Os resultados dos estudos aqui descritos sugerem que a suplementação com cromo melhora a homeostase dos peixes favorecendo a resposta imune e o desempenho zootécnico.

Background

Men of African ancestry experience higher burden from prostate cancer compared to men of other ancestral backgrounds. Limitations in the availability of high-quality biospecimens hinder the inclusion of this population in genetic studies of prostate cancer. The use of formalin-fixed paraffin-embedded (FFPE) tissues represent a potential rich source of genetic material particularly in some international settings, where fresh frozen tissue is difficult to obtain. In this study, we investigate the feasibility of using FFPE biospecimens acquired from various international sites for utility in next-generation sequencing.

Methods

A total of 976 FFPE blocks were collected between 2002 and 2017 from six international sites in Africa and the Caribbean representing three consortia: Prostate Cancer Transatlantic Consortium; African-Caribbean Cancer Consortium; and Men of African Descent and Carcinoma of the Prostate. Genomic DNA was checked for quality and quantity. Differences in mean quality control (QC) for pre-and-post pathology training were assessed using t-test. Pearson chi-square with trend analysis examined association between time-category and QC success status. Association of continuous DNA quality (Q129/Q41 ratio) and time of specimen collection was estimated with linear regression. Samples with a DNA quantity >0.2µg and a Q129/Q41 ratio >0.00225 were submitted for whole exome sequencing (WES).

Results

There was a positive relative percentage change in DNA quantity from 2002 to 2017 for Jamaica, Kenya and Senegal. There was a decline in DNA quantity over the same time period for Nigeria. There was a statistically significant improvement in quality of samples from Kenya (P=0.032), Nigeria (P<.001) and Senegal (P=0.043). There was a significant improvement in the collected DNA sample quality over time with an R2 of 0.12.

Conclusions

FFPE samples from low-resource settings could potentially provide sufficient DNA for WES. Improvements in biospecimen collection processing and storage for research are needed in some of these settings.
Revelando el Agotamiento del NH3 en los Nucleos Preestelares.
Authors:   , Gavino Stefano
Published: August 2023

Molecular clouds are regions in the interstellar medium where molecular H2 lies and accumulates. When the concentration of molecular hydrogen becomes high enough, the properties of the region that contains it begin to change, preparing it for the collapse that, with enough evolution, will form new stars. These high-density regions are normally known as Cores, receiving a name depending on their state of evolution, starting from starless cores where there is a clear over-density but no gravitational bonding, to pre-stellar cores, where gravity plays an important role in the core dynamics. Pre-stellar cores have been extensively studied and recognized for having very special chemical traits that are expected to determine the future of the stars that will be born from them. In these terms, one specific and important property of pre-stellar cores is the high level of depletion of heavy species into dust grain surfaces. Ammonia (NH3) had been flying under the radar for more than a decade because, as observed in some observational projects, it does not freeze out as hard or at all as C and Obased molecules. In this work, we study the creation and evolution of NH3, its deuterated isotopologues, and spin isomers, making use of up-to-date chemical post-processing over the results of a state-of-art 3D hydrodynamic numerical simulation. We used this chemical post-processing scheme to see how changing some parameters affects the behavior of NH3 on an evolving slow collapse pre-stellar core and compared the results to observations. We find that a high value of CRIR, even if that is quite difficult under pre-stellar core conditions, can increase NH3 abundance and decrease the effects of freeze-out over it, while smaller grain sizes and high ortho-para ratios promote depletion heavily. We also explore the effects of implementing a density dependence for gas and dust temperatures and CRIR, which showed slight improvements from the worst isothermal cases; in particular, in the densitydependent CRIR case, we got results close to the best regular cases. We then compare our findings, mostly qualitatively, with a couple of more up-to-date observational works than our reference one, probing that our post-processing scheme, both in isothermal and densitydependent cases, can roughly recover the observed column densities on these publications, which validates our approach. We conclude that most of the parameters we have explored have a relatively weak role when we talk about regulating ammonia depletion, but there are some exceptions, as is the case when CRIR is high. Also, we find that our fiducial run does not have the best agreement with the reference case as we expected when contrasting them all, but its abundance profile is congruent with the observations over the whole evolutionary process.
Evaluación de Citoquinas y Quimioquinas y Su Asociación con Secuelas Pulmonares en Pacientes Post COVID-19
Authors:   , Nova Lamperti Estefanía Andrea
Published: August 2023

La COVID-19 grave se caracteriza por una marcada liberación de citoquinas y disfunción pulmonar; sin embargo, aún se desconoce qué mediadores sustentan la disfunción pulmonar posterior a la COVID-19. Nuestro objetivo fue determinar las vías de señalización asociadas con la disfunción pulmonar a largo plazo en pacientes con COVID-19. Nuestra cohorte de 60 pacientes con COVID-19 fue seguida a los 4 y 12 meses posteriores a la infección. Las secuelas pulmonares se analizaron mediante tomografía computarizada (TC), capacidad de difusión de monóxido de carbono pulmonar (DLCO), espirometría, prueba de caminata de 6 minutos (6MWT) y prueba de agarre manual (HGS). También se analizaron citoquinas, quimioquinas y parámetros de análisis sanguíneo. Además, las vías de señalización asociadas con la disfunción pulmonar se identificaron mediante análisis de proteómica sérica utilizando TimsTOF-Pro y análisis de vías de ingenio. Catorce pacientes con TC y DLCO anormal fueron clasificados como pacientes con disfunción pulmonar a largo plazo (DPLP), quienes además presentaban un mayor número de alteraciones en las pruebas de espirometría, 6MWT y HGS frente a los pacientes sin secuelas o pacientes con solo TC anormal. Observamos que solo CXCL-9 aumentó significativamente en pacientes con DPLP en comparación con otros grupos. Además, las principales vías de señalización identificadas por proteómica en pacientes con DPLP se asociaron con un estado inmunotrombótico relacionado con disfunción cardíaca, migración de monocitos disfuncionales y señalización reducida de IFN-γ. En resumen, los pacientes con DPLP presentaron una condición pulmonar restrictiva, con mayor fatiga, menor capacidad aeróbica y fuerza muscular 4 meses post-COVID-19. Nuestros datos sugieren que los pacientes con disfunción cardíaca previa y que presentaron COVID-19 grave o moderado son más susceptibles de desarrollar DPLP.
Efecto del Tratamiento Térmico en la Vida a la Fatiga en Flexión para un Compuesto de Onyx Reforzada con Fibra de Vidrio Impreso en 3D.
Authors:   , Medina Muñoz Carlos
Published: August 2023

En los últimos años la impresión 3D o 3DP se ha ampliado para incluir a los materiales compuestos, donde, los filamentos de polímeros y los de refuerzo son extruidos juntos durante la impresión. En general, gran parte del desarrollo investigativo se ha llevado a cabo para los polímeros impresos reforzados con fibra corta, partículas, microfibra, entre otros refuerzos cortos; mientras que la investigación para polímeros reforzados con fibra continúa impresos en 3D se encuentra en una etapa joven de desarrollo. En el presente informe se investiga la vida a la fatiga en flexión para un material compuesto de Onyx reforzado con fibra continua de vidrio impreso en una impresora Marktwo de Markforged. Esta investigación aborda el estudio sobre el efecto en la vida a la fatiga en flexión al aplicar un tratamiento térmico de 175°C por 6 horas a un compuesto de Onyx reforzado con fibra continua de vidrio impreso en una impresora Markforged. También se analiza el efecto del tratamiento térmico en los vacíos y porosidades del compuesto. Para estudiar la vida a la fatiga en flexión, se utiliza la flexión con 3 puntos de apoyo. Se define una geometría con relación de espesor- distancia de apoyos de 16:1. Primero, se realizan ensayos de flexión cuasi estática a una velocidad de 2 [mm/min], para determinar la carga máxima monotónica del material, con el fin de poder definir los límites de los niveles de carga. Para los ensayos de fatiga, se define una razón de amplitud R de 0.1. Se ensayan 5 especímenes por nivel de carga y la velocidad del cabezal es de 20 [mm/s]. El análisis de los datos para obtener la vida a la fatiga se realiza mediante la distribución Weibull de dos parámetros. Se analizan las porosidades de los especímenes de ambos grupos mediante micrografías, obteniéndose una reducción del 40,68% en los vacíos para el grupo con tratamiento térmico. Esta reducción en las porosidades va acompañada con un aumento del 70% en el esfuerzo máximo promedio y un 40% de la rigidez en el ensayo de flexión cuasi-estática. Esta mejora se relaciona directamente con la reducción de los vacíos, debido a que se genera una interfaz fibra-fibra y fibramatriz más fuerte, también la cristalización del nylon producto del aumento de la temperatura contribuye al mejoramiento de las propiedades mecánicas. Con respecto a la vida a la fatiga en flexión, se observa una reducción en todos los niveles de carga para el grupo con tratamiento térmico. Esta reducción se atribuye a la degradación sufrida por la matriz debido a las altas temperaturas. Evidenciándose en la ruptura de la matriz en todas las fallas durante los ensayos de fatiga.

The purpose of this study was to examine the blood glucose level, lipid profile, and histology of alloxan-induced diabetic rats fed compounded diet of Sesamum indicum. 36 male albino rats were divided into nine groups of four each for a period of 21 days: normal control, diabetic control, treated with the standard medication glibenclamide, diabetic rats fed with 15%, 30%, and 60% compounded diet, and normal rats fed with 15%, 30%, and 60% compounded diet and induced with diabetics after 14 days. single intraperitoneal injection of freshly produced alloxan (120 mg/kg b.wt.) was used to induce diabetes. Acu-check glucometer was used to measure the blood glucose level, and conventional spectrophotometric method was used to measure the lipid profile level. When compared to the diabetic control group, which had glucose level above 200, the groups fed the compounded diet had decreased level. Significant (p<0.05) reduction was observed for cholesterol, triglyceride, and low-density lipoprotein when compared with diabetic control while the compounded diets were able to increase HDL that was found to be low in diabetic control. When compared to the diabetic control group, which displayed a damaged pancreas, the results from the histopathology of the pancreas showed that the groups fed with the compounded diet had a repaired pancreas. According to the study's findings, Sesamum indicum has the ability to reduce excessive blood glucose and cholesterol levels as well as mend a diabetic rat's deformed pancreas.

This study aims to determine whether there is an increase in the learning outcomes of running 60 meters through a playing approach for fifth grade students at SD Negeri 2 Masohi. The data obtained through classroom action research (CAR) was carried out in three cycles, namely cycles I, II and cycle III. Data for each cycle were obtained from observations and performance tests based on the indicators assessed in the assessment rubric. Furthermore, all scores obtained by each student, divided by the maximum score multiplied by one hundred percent (100%), will obtain the value of each student. This value is the final result obtained by each student which will determine whether the student is declared complete or not so that it can be continued in cycles II and III. After taking action in cycle I, the results of learning to run a distance of 60 meters with a playing approach were 28.76%. After being given action in cycle II, from 28.76% it rose to 67.87%, there was an increase of cycle III from 67.87% rose to 78.38% there was an increase of = 10.51%. Based on the results found in the implementation of the research described above, (Pupuh and M. Sobry Sutikno, 2007), explains that learning is essentially a "change" that occurs within a person after carrying out certain activities. Based on this theory, in the implementation of actions or learning carried out in 3 cycles, there are changes that occur in each cycle both in attitudes (affective), knowledge (cognitive) and skills (psychomotor). Thus it can be concluded that the play approach can be used to improve the learning outcomes of 60 meter running in class V SD Negeri 2 Masohi.

From the results of pre-action observations conducted in July, odd semester of the 2019/2020 Academic Year, students have not been able to practice long jump properly. The approach that can be taken to overcome problems in long jump learning is through modification of learning media. Teachers are stimulated to be able to create innovative forms of learning assisted by modifications of learning media in the learning process in the form of Kasrdus media. Therefore it is necessary to have an approach to improve learning in the squat style long jump, especially in the aspect of repulsion in fifth grade students of Seruawan State Elementary School, Kairatu District. Based on the empirical facts and theoretical facts above, the authors are interested in conducting classroom action research on "Improving Learning Outcomes of the Squat Style Long Jump Through Modification of Learning Media in Class V Students of Seruawan State Elementary School, Kairatu District"

Die Wiederbelebung unterbrochener Bindungen
Authors: Kidron Carol A.
Published: August 2023

Diese vergleichende Studie untersucht die Wege, auf denen israelische Nachfahren des Holocaust und die Nachfahren des kambodschanischen Völkermordes die ›unterbrochenen‹ Nachfahren-Vorfahren-Beziehungen mit den persönlich nie gekannten Toten des Genozids wiederherstellen. In der empirischen Untersuchung der Art und Weise, wie entfernte Verbindungen, die in Zeiten des Krieges und des massiven Leidens ›unterbrochen‹ wurden, im alltäglichen Leben wiederhergestellt werden, füllt diese Untersuchung eine Leerstelle der Forschung über die Folgen von Völkermorden, die fortbestehenden Bindungen und den Kontakt zwischen dem Einzelnen und den Verstorbenen. Die Nachkommen zeigen Wege einer Verbindung mit den Toten auf, zu denen der Kontakt zwischen dem einzelnen Menschen und dem Toten gehört, die Interaktion zwischen Mensch und Objekt, das vorgestellte Gespräch, die jeweils eine Kopräsenz und eine Intersubjektivität konstituieren. Im Gegensatz zu Traumatheorien sowie Holocaustund Genozidstudien wie auch zur Anthropologie der Abwesenheit, welche die Beziehung zu den Toten auf eine maladaptive Identifikation oder eine belastende Gegenwärtigkeit einer entleerten Abwesenheit reduzieren, weisen die Ergebnisse auf normalisierte und ermächtigende Beziehungen hin. Die Ergebnisse des Vergleichs tragen zu unserem Verständnis bei, wie die Art und Weise kulturübergreifender Bedeutungsstiftung die durchlässige Grenze zwischen den Lebenden und ihren Ahnen unterschiedlich konzeptualisiert und die Wiederherstellung (dis)kontinuierlicher Bindungen prägt.
