Los residuos que se generan por el proceso al fruto del café (cáscara, pulpa, cascarilla o piel plateada), y por la preparación de la bebida (bagazo), son una fuente importante de nutrientes y cuya extracción es una estrategia potencial para la obtención de nuevos aditivos alimentarios, razones por las que en este trabajo se presente una recopilación de los resultados de los estudios sobre sus nutrientes, sus componentes bioactivos, la extracción de estos compuestos, la evaluación de su actividad antioxidante y su posible aplicación en la carne fresca y en los productos cárnicos. De acuerdo a los estudios realizados, los residuos del café (harinas y extractos) contienen compuestos fenólicos como los ácidos fenólicos y los flavonoides, con actividad antioxidante (antirradical y poder reductor). Los compuestos bioactivos se obtienen por métodos convencionales (maceración y Soxhlet), no convencionales (alta presión hidrostática, microondas y ultrasonido) y biotecnológicos (fermentación fúngica). También se muestra que tanto las harinas como los extractos de estos residuos tienen un efecto positivo sobre la estabilidad oxidativa de la carne (cerdo, cordero y pollo) y los productos cárnicos (hamburguesas y salchichas).
La normativa laboral española ante el Covid-19: cronografía de una pandemia
Authors: Escribá Pérez Ana Nieves
Published: March 2023

Desde el 14 de marzo de 2020 se han producido cambios importantes en materia legislativa en nuestro país. Ha sido necesario que nos adaptemos rápidamente a los cambios que han acaecido en la sociedad actual, tal y como la conocemos hoy en día. El Covid-19 ha irrumpido en nuestras vidas y, por lo que hoy sabemos, lo ha hecho para quedarse. A lo largo de marzo y abril han aparecido reales decretos-ley encargados de regular las cuestiones más preocupantes en todos los ámbitos de la convivencia social y, por supuesto, en el ámbito del derecho, como no podía ser de otro modo, se han hecho necesarios para regular las cuestiones relacionadas con los aspectos laborales. Ha sido necesario regular y aclarar cuestiones como la suspensión temporal de los contratos de trabajo, la prestación por desempleo, las cotizaciones a la seguridad social, el teletrabajo, la prestación por aislamiento, el permiso retribuido recuperable o el contagio debido al Covid-19 —entre otros—. Somos conscientes, día a día, de las implicaciones que todos ellos han tenido a lo largo de estos dos meses, pero ahora tendremos que esperar para ver qué ocurre en un futuro no muy lejano.
Moral, derecho y sociedad. Reflexiones interdisciplinarias sobre la crisis moral en el caso latinoamericano
Authors: Botero Bernal Andrés
Published: March 2023

Este escrito plantea la complejidad sistémica del concepto crisis moral aplicada en la sociedad contemporánea, especialmente en el caso latinoamericano, lo que exige un estudio interdisciplinario para abordar el asunto. Ahora bien, se alude a una complejidad sistémica de la crisis moral por cuatro aspectos. En primer lugar, porque la moral, al ser un sistema normativo basado en el deseo de una sociedad mejor, nunca se sentirá satisfecha de la sociedad en la que se enmarca, lo que provoca un permanente malestar. En segundo lugar, porque una crisis moral indica que no hay un acoplamiento entre la realidad de lo que se tiene con lo que se quiere, por lo que el acoplamiento deseado supone interrelacionar diversas variables sistémicas para que pueda suceder realmente un desarrollo moral (para lo cual se seguirá, con algunas correcciones, el modelo de desarrollo moral de Kohlberg), variables que son más complejas de lo que el sistema político cree o quiere hacer creer. En tercer lugar, porque afirmar la existencia de una crisis moral y, por tanto, la necesidad de acciones tendientes a resolverla, no implica que haya consenso sobre cuál es la moral que debe aceptarse ni sobre el camino a seguir para lograr dicho fin, para empezar porque es relativamente común que los agentes acusados de ser los causantes de la actual “crisis moral de la sociedad y del derecho” en las sociedades contemporáneas suelen ser los agentes que denuncian, como free riders, la misma crisis. Y, en cuarto lugar, porque un cambio sistémico que posibilite un salto en el desarrollo moral debe ser significativamente fuerte, y las medidas que suelen enunciarse para afrontarlo, además de no ser claras, suelen ser insuficientes o ingenuas (tales como pedir la creación o el fortalecimiento de una asignatura de ética en los planes de estudio de los futuros ciudadanos en general y abogados en especial). Finalmente, se propondrá partir de este diagnóstico sistémico e interdisciplinario para potencializar las respuestas que puedan darse para enfrentar la crisis; de lo contrario, lo rechazado permanecerá.
Detection and Identification of Non-Helmet Riders and Their License Plate Numbers
Authors: Arshad Sheik , Prasanthi Birali
Published: March 2023

Abstract: Due to the ever-increasing number of vehicles a variety of traffic regulations are imposed and are addressed using various approaches. Two-wheelers are the most preferred and commonly used vehicles among the youth due to their cost. Bike riders are highly supposed to use helmets, but wearing helmets is often neglected by bike riders leading to accidents and deaths. Riding a bike without a helmet is a traffic offense. While riding a motorcycle/bike, the rider and as well as the pillion rider should wear a helmet according to the traffic rules of road safety. In the current system, traffic offenses are largely monitored by the traffic police by investigating CCTV records. The traffic police zoom into every frame of the CCTV record and tries to identify the license plates of non-helmet riders. This will take a lot of labor and time. The proposed system uses deep learning algorithms, CNN (convolutional neural networks) to analyze real-time video footage from cameras installed in key locations, such as roads and intersections, to identify individuals riding without helmets. The proposed system is expected to significantly reduce the number of non-helmet riding incidents and, therefore, decrease the number of fatalities and serious injuries resulting from motorcycle accidents.
Square-shaped wooden churches in Zavolzhsky District of the Nizhny Novgorod Region. New typological studies
Authors: Bode Andrey B. , Voevodin Ilya V. , Zhigaltsova Tatiana V.
Published: March 2023

Introduction. The study focuses on typology of square-shaped wooden churches, namely, three virtually unexplored wooden churches that date back to the 17th–18th centuries. They are located in Zavolzhsky district of the Nizhny Novgorod region. This study discovers new, previously unknown architectural solutions. This work is valuable for the practical preservation and restoration of cultural heritage items. The goal of the study is to analyze architectural and construction traditions typical for wooden churches in Central Russia. The objectives of the study include field surveys of the church facilities, review of archived and literary sources, identification of construction periods, comparison of similar construction facilities, and consolidation of distinctive features of wooden churches in Central Russia.

Materials and methods. This work employs a comprehensive approach combining practical restoration methods and research methods of comparative topological, historical, and evolutionary analysis. By adding architectural solutions to the general timeline of wooden architecture, the authors identify architectural solutions, techniques and forms typical for Central Russia.

Results. The following church facilities were studied: Church of the Ascension of the Lord dated 1703 (late 19th century) in Zarubino, Gorodetsky district; Church of the Life-Giving Trinity dated 18th–19th century in Khudyakovo village, Gorodetsky district; Church of the Nativity dated 1776 in Gari village, Sokolsky district. Construction periods and original architectural design were identified. The function and architectural features of the church facilities were identified. These were cold (summer) square-shaped churches with spacious premises capable of accommodating considerable numbers of people. As to their forms, these structures generally demonstrate all the typological features of square-shaped churches, except for their size and absence of heating.

Conclusions. The subgroup of cold square-shaped churches, known for their large size, was identified within the typological group of square-shaped wooden churches. As heated wooden churches turned more frequent, church complexes having two same-type buildings — cold and warm — were constructed.
Further introduction of information modelling technologies in the course of implementation of investment projects in the field of housing construction
Authors: Larionov Arkady N. , Prikhodko Anton V.
Published: March 2023

Introduction. Modern housing construction requires (1) a single digital platform that has a common data environment, (2) workflow digitization, involving all stakeholders of an investment and construction project. The authors demonstrate that the implementation of this approach will ensure not only the monitoring and control of financial values of construction, including disbursement schedules and a single consolidated database for all documents on each construction project showing access rights to information, but it will also ensure the integrity and reliability of information required for the implementation of day-to-day urban planning activities, as well as quick and flexible integration with state information systems.

Materials and methods. Optimization methods were used to find rational engineering and economic solutions for investment and residential housing construction projects. Multivariance was employed to substantiate the applicability of solutions in the process of introducing digital BIM technologies aimed at identifying the most effective project options.

Results. The main result of the presented research is the application of the G. Taguchi loss function to devise a model for assessing the economic efficiency of options of an investment and construction project, that take into account the total loss of economic efficiency in the course of implementing various technologies of an investment and housing construction project.

Conclusions. The results enable the co-authors to use the proposed model to evaluate the economic efficiency and to identify (1) options of an investment and housing construction project, (2) the range of acceptable options of project implementation that are economically feasible, as well as (3) ranges of unacceptable project implementation options that are “too bad for the consumer” and “too expensive for the producer”; (4) the best project option; (5) the way to improve the generalized algorithm of BIM technology application in practical housing construction.
Hybrid divide-and-conquer approach for tree search algorithms

Published: March 2023

One of the challenges of quantum computers in the near- and mid- term is the limited number of qubits we can use for computations. Finding methods that achieve useful quantum improvements under size limitations is thus a key question in the field. In this vein, it was recently shown that a hybrid classical-quantum method can help provide polynomial speed-ups to classical divide-and-conquer algorithms, even when only given access to a quantum computer much smaller than the problem itself. In this work, we study the hybrid divide-and-conquer method in the context of tree search algorithms, and extend it by including quantum backtracking, which allows better results than previous Grover-based methods. Further, we provide general criteria for polynomial speed-ups in the tree search context, and provide a number of examples where polynomial speed ups, using arbitrarily smaller quantum computers, can be obtained. We provide conditions for speedups for the well known algorithm of DPLL, and we prove threshold-free speed-ups for the PPSZ algorithm (the core of the fastest exact Boolean satisfiability solver) for well-behaved classes of formulas. We also provide a simple example where speed-ups can be obtained in an algorithm-independent fashion, under certain well-studied complexity-theoretical assumptions. Finally, we briefly discuss the fundamental limitations of hybrid methods in providing speed-ups for larger problems.

Published: March 2023

Following delivery, women may feel a variety of pains and discomforts, including cramping pain brought on by uterine involution, in which the uterus contracts to stop blood loss and return to its pre-pregnancy size. This study examined the impact of kegal exercise and the prone posture on postpartum moms' spasmodic discomfort and uterine involution. “The research design selected for the study was pre experimental research design”. “Non Probability purposive sampling techniques” were used to collect 60 postnatal mothers. “Numerical pain rating scale to assess pain and clinical proforma to assess involution of uterus” was administered to conduct the pre-test and the post test. Each sample received the Kegel exercise (10 secs three times per day for three days) and the prone position (3 to 5 mints three times per day for three days) after the pretest pain and fundal height levels were evaluated. After three days, the same scale was used to assess pain and fundal height. The mean scores for the fundal height and pain pre-tests were 7.66 and 7.83, respectively. Post-test mean scores for fundal height and pain were 3.86 and 4.1, respectively. The pre-test fundal height and pain score had standard deviations of 1.77 and 1.37, and the post-test fundal height and pain score had standard deviations of 1.86 and 2.00. Age, educational attainment, and age of menarche were important factors in the calculated chi square value, but other variables were insignificant. The study's findings supported the notion that the prone posture and the Kegel exercise helped postpartum mothers' fundal height and pain.
Parameter Estimation for Balance-Equal Replicated Linear Functional Relationship Model: An Application to the Wind Directional Data

Published: March 2023

A linear functional relationship model can be used to model the relationship between two circular variables when both variables are observed with errors. When the ratio of error concentration parameter is unknown, it is suggested that the replicated linear functional relationship model be used. The purpose of this paper is to present all the parameter estimates of the replicated linear functional relationship model for balance replicates and equal circular variables. Simulations studies are performed to study understand the behavior of the parameter estimators for the balance-equal replicated linear functional relationship model. The empirical results obtained suggest that the proposed parameter estimation method performs well with small bias. A simple application of the model is demonstrated by analyzing a real dataset of a wind directional data.
In vivo and in vitro study on the mechanism of anti-cervical cancer effects of Corilagin in mice

Published: March 2023

Corilagin has several pharmacological effects such as anti-tumor,
anti-inflammatory, and cardiovascular disease treatment. Our previous
studies have shown that the Corilagin can significantly inhibit
proliferation of HeLa cells. However, there is no scientific data on the
anti-cervical cancer effect of Corilagin in vivo. It was speculated that
the mechanism of action for the anti-cervical cancer of Corilagin could
be related to PI3K/AKT and MAPK signaling pathways through network
pharmacology. Results of cell assays in the present study showed that
the Corilagin has significant effect on the proliferation, cell cycle
and apoptosis of murine cervical cancer U14 cells in vitro. In addition,
Corilagin can significantly inhibit the growth of U14 tumor-bearing mice
with insignificant toxic effect on liver and kidney of the transplanted
mice. The current study found that Corilagin can delay development of
cervical cancer by boosting anti-tumor immune responses of body. RT-PCR
and Western blotting were applied in the current study to evident that
Corilagin can achieve anti-cervical cancer property by inducing
apoptosis of tumor tissues through both PI3K/AKT and MAPK signaling
pathways. Therefore, this study provided theoretical reference for
research of Corilagin as a bio-resource for development of an
anti-cervical cancer drug and functional food.
Estimating and planning hospital costs of public hospitals in Brazil
Authors: Almeida João Flávio , Conceição Samuel Vieira , Magalhães Virginia Silva , Alemão Márcia Mascarenhas
Published: March 2023

While the estimate of hospital costs concerns the past, its planning
focus on the future. However, many public hospitals in low and
middle-income countries don’t have robust accounting health systems to
evaluate and project their expenses. In Brazil, public hospitals are
funded based on government estimates of available hospital
infrastructure, historical expenditures and population needs. However,
these pieces of information are not always readily available for all
hospitals. To solve this challenge, we propose a flexible
simulation-based optimisation algorithm that integrates this dual task:
estimating and planning hospital costs. The method was applied to a
network of 17 public hospitals in Brazil to produce the estimates.
Setting the model parameters for population needs and future hospital
infrastructure can be used as a cost-projection tool for divestment,
maintenance, or investment. Results show that the method can aid health
managers in hospitals’ global budgeting and policymakers in improving
fairness in hospitals’ financing.

ABSTRACT This study compared four different transformation techniques by applying a simple linear regression on raw and transformed data. The R2 of each model was obtained and a test on the significance of these R2 was carried out. Also, the rxy(coefficient of correlation) were also obtained. The data used is a secondary data consisting of 53years (1964-2016) of the infant mortality rate in Nigeria (https://www.ceicdata.com/en/nigeria/health-statistics/ng-mortality-rate-infant-per-1000-live-births). The rxy were also compared and the results, 95.8%, 95.8%, 96.2%, 93.0%, and 92.9% respectively. The R2 obtained for the raw data, logarithm, square-root, square and inverse are as follows: 91.8%, 91.7%, 92.5%, 86.6% and 86.4% respectively. However, the R2 obtained for the raw data, logarithm, square-root, square and inverse compete favourably but the performance of inverse transformation suits the data most in terms of model accuracy.

Artificial network modelling are being used in areas of prediction and classiﬁcation, areas where classical regression models and other related statistical techniques have traditionally been used. This study is aimed at comparing the Logistic Regression Model and the Perceptron Neural Network Modelling to detect the malignancy or benignancy of the tumorous cell of cancer patients more accurately. Data from the Breast Cancer Wisconsin (Diagnostic) was analysed using the Classical Regression Model and the Perceptron model. The study compared both Binary Logistic Model (BLM) and the Perceptron Neural Model (PNM) by their level of accuracy in predicting the breast cancer outcome. The Perceptron model had greater accuracy (98.3%) than the Binary Logistic Model (97.2%) This goes to show that the Perceptron Neural Network Model was a better predictive model as it had a higher accuracy in predicting the cancer model. The study also found that both the perceptron neural networks and logistic regression models can remarkably predict cancer very close to the actual values but the performance of the perceptron neural network model for prediction of cancer was higher and more precise. The study recommends that Perceptron neural network model as a better alternative to the Logistic Regression Model. Keywords: Logistic Regression, Perceptron, Classical, Neural Network

OBJECTIVE

Car dependency contributes to physical inactivity and, consequently, may increase the likelihood of diabetes. We investigated whether neighborhoods that are highly conducive to driving confer a greater risk of developing diabetes and, if so, whether this differs by age.

RESEARCH DESIGN AND METHODS

We used administrative health care data to identify all working-age Canadian adults (20–64 years) who were living in Toronto on 1 April 2011 without diabetes (type 1 or 2). Neighborhood drivability scores were assigned using a novel, validated index that predicts driving patterns based on built environment features divided into quintiles. Cox regression was used to examine the association between neighborhood drivability and 7-year risk of diabetes onset, overall and by age-group, adjusting for baseline characteristics and comorbidities.

RESULTS

Overall, there were 1,473,994 adults in the cohort (mean age 40.9 ± 12.2 years), among whom 77,835 developed diabetes during follow-up. Those living in the most drivable neighborhoods (quintile 5) had a 41% higher risk of developing diabetes compared with those in the least drivable neighborhoods (adjusted hazard ratio 1.41, 95% CI 1.37–1.44), with the strongest associations in younger adults aged 20–34 years (1.57, 95% CI 1.47–1.68, P < 0.001 for interaction). The same comparison in older adults (55–64 years) yielded smaller differences (1.31, 95% CI 1.26–1.36). Associations appeared to be strongest in middle-income neighborhoods for younger residents (middle income 1.96, 95% CI 1.64–2.33) and older residents (1.46, 95% CI 1.32–1.62).

CONCLUSIONS

High neighborhood drivability is a risk factor for diabetes, particularly in younger adults. This finding has important implications for future urban design policies.

Cancer refers to any disease among a large number of diseases characterized by the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissues. Cancer often has the ability to spread throughout the body. Cancer is the second leading cause of death in the world

Cancers can occur in any part of the female reproductive system — the vulva, vagina, cervix, uterus, fallopian tubes, or ovaries. These cancers are called gynecologic cancers.

Gynecological cancers can invade directly nearby tissues and organs, or spread (metastasize) through the lymph vessels, lymph nodes (lymph system), or the bloodstream to distant parts of the body.Breast cancer occurs when some breast cells begin to grow in an abnormal way. These cells divide more rapidly than healthy cells and continue to accumulate, forming a lump or tumor. The cells may spread (metastasize) through the breast to the lymph nodes or to other parts of the body.

Interleukin-12 (IL-12) is an anti-inflammatory cytokine that links innate and adaptive immune responses against cancer cells. Single nucleotide polymorphisms (SNPs) in the IL-12 genes have been associated with cancer risk. The role of IL-12 in breast cancer  and gynecological risk overall, association of the IL-12 signaling pathway and BC risk in women.

Asthma and chronic obstructive pulmonary diseases (COPDs) have been identified as one of the serious, public health concerns in the world, which results due to the host as well as the environmental factors. Based on the WHO, this disease will be the 3rdkiller disease worldwide by the year of 2020 following the cancer and heart disease. Concerning the asthma, there have been 389,000,000 individuals worldwide, afflicted by COPD and Asthma. Moreover, there has been a noticeable increase in the asthmatic incidences in the young adults and children by 4% to 5% yearly worldwide. Those two illnesses are fundamental global morbidity and mortality reasons, particularly in the patients that respond poorly to the current treatments. Which is why, there are unmet needs to come up with innovative therapies for the COPD as well as the asthma patients. Bitter taste receptors (TAS2R) are part of the family of the G-protein coupled receptors (GPCR). It was theorized previously that the TAS2R only expression on the tongue’s taste buds. The family of the TAS2R includes over 25 different subtypes of the receptors in the humans. Lately, a number of the researches showed that the TAS2R could be representing a new treatment target of the lung diseases. The TAS2R has been expressed in the human air-way smooth muscles (ASMs). It should be noted that TAS2Ractivation by the saccharin and chloroquine results in the induction of air-way relaxation. More significantly, bronchodilatory effects that result from the TAS2R agonists has been found greater compared to the β2 adrenergic receptor agonists, the basic bronchodilator medications in treating asthma. the bronchial airway smooth muscle (BASM) cells have been cultured from COPD (n=3), asthmatic (n=3), and healthy (n=3) individuals. The Immuno-fluorescence staining (with and with no permeabilize cells) have been conducted on 3 groups with the use of the poly-clonal anti-bodies against the (TAS2R10 as well as the TAS2R14) receptors. The immuno-fluorescence assays had shown that the TAS2R10 and TAR2R14 had shown a positive staining of the two receptors in the human ASM cells. It has been discovered as well that those two receptors have been expressed as well in nucleus.

El presente artículo plantea una reflexión sobre la división sexual del trabajo de las mujeres en el campo de la música a partir de algunos conceptos desarrollados por teóricas del feminismo materialista francés. La reflexión se centra en la tesis desarrollada por Paola Tabet sobre el subequipamiento técnico de las mujeres, vinculado a los conceptos de relaciones sociales estructurales entre los sexos (Nicole-Claude Mathiew) y apropiación (Collete Guillaumin) como categorías nodales para pensar las distintas formas en que se produce y sostiene la desigualdad. Partiendo de la ley de cupo femenino para pensar sobre el acceso diferenciado a los medios de producción musical (instrumentos y tecnología), se toman también algunos de los aportes desarrollados por Lucy Green en torno a la música y el género en contraste y vinculación con las ideas propuestas por Tabet y Guillaumin.

Authors:   Korea Univ. Institute of Educational Research, Seo Kyung wha
Published: March 2023

The purpose of this study is to derive groups based on the first job satisfaction pattern of science and engineering graduates, and to explore the characteristics of university institutions that influence the classification of each group. Six potential groups of first job satisfaction were extracted for science and engineering graduates through the definition of the first job satisfaction, and as predicted variables of each group, the level of agreement between jobs and college education that can be intervened at the individual and school level, and university education satisfaction factors was verified. The subjects of this study were 1058 students who graduated from the science and engineering college of the ‘2018 College Graduates’ Vocational Movement Path Survey (2017GOMS)’, and latent hierarchical analysis, crossover analysis, and logistic regression analysis were performed as data analysis methods. The summary of the research results is as follows. First, 6 potential groups were extracted; ‘welfare passive type’, ‘dissatisfied type’, ‘aptitude interest matching passive type’, ‘personnel system active type’, ‘satisfied type’, ‘maximum satisfied type’. Second, factors that are impossible and possible to intervene and change at the university level were derived. Based on the main research results, it was suggested that changes and innovations in science and engineering education are possible only when changes in the method and quality of instruction are preceded by professors. First, each university needs to establish a specialized engineering curriculum that can promote win-win development with the local community. Second, a systematic engineering career path and career development process linked to university education is required.

Published: March 2023

This study is to analyze the educational effects of the edutech content support project targeting vulnerable students. In particular, it was intended to explore the self-directed learning ability among the effects of the edutech content support project. To analyze the improvement in the self-directed learning ability of the vulnerable students receiving the edutech content support, a pre- and post-test was conducted. The study results are as follows. As a result of group difference analysis of self-directed learning ability, there are statistically significant differences by gender, school, and region in the cognitive and behavioral domains. In the affective domain, there was statistically significant difference by school and region. There was no statistically significant difference in pre-post scores for each domain of self-directed learning ability. However, the mean scores were all high in the posterior test. Suggestions through this are as follows. First, a long-term support project using edutech contents is necessary. Second, it is necessary to provide an active mentor service to complement the emotional aspects of students from the underprivileged beyond learning. Third, it is necessary to support edutech services that include support from mentors or tutors for vulnerable students who do not receive active parental protection or academic support.
The Chronology of Monte d’Accoddi (Sardinia, Italy) – New Radiocarbon Dates

Published: March 2023

The shrine at Monte d’Accoddi constitutes an architectural unicum in the context of the Mediterranean of the 4th millennium cal. BC. The building comprised of a terrace with an access ramp, a form that has led to an ongoing debate as to the possible origins of this architectural model. In its earliest phase, attributable to the first half of the 4th millennium cal. BC, the edifice consisted of a truncated pyramidal core. During the second half of the same millennium this was englobed by a second building, similar to the first in general shape, but much larger and with a central, possibly stepped, core. The site was occupied during the 3rd millennium cal. BC and occasionally so during the following proto-historic and subsequent phases of history. This paper will present new radiocarbon dates that will help to define the construction and occupation phases of the monument as well as the settlement that grew around it.

The present study concerns the archaeobotanical analysis of soil samples and vase fillings from Etruscan tombs from the Necropolis of “Valle Santa nell’Agro Veientano”, found along via di Boccea, north of Rome (Italy). While the site was in use between the Archaic and Late Roman Age, the studied vestibule tombs belong to the Etruscan necropolis (second half of the 6th – beginning of the 4th centuries BC). Archaeological data, based on the incineration rite and funerary equipment, suggest that these were used by one high-status family (or two) originally from Veio. Carpological analyses reveal the presence of food plants comprised of cereals, pulses and fruits. Furthermore, anthracological data give indications concerning the past environment, with a prevalence of deciduous and semi-deciduous oaks, accompanied by other taxa such as evergreen oaks, hornbeam, ash and Rosaceae Prunoideae. This is in accordance with the present-day vegetation of northern Latium. Finally, remains of synanthropic weeds (e.g., Asteraceae, Caryophyllaceae and Polygonaceae) suggest a heavily anthropized environment. This study represents a step forward in the understanding of the still under-explored human-plant interactions of Etruscans.
The Possibilities and Results of Magnetometer Survey in Small-Sized Fortifications of the High Middle Ages. A Case Study on Research into Manorial Residences in the 14th to 15th Century in East Bohemia
Authors:   Department of Archaeology, Faculty of Arts, University of Hradec Králové, Rokitanského 62, 500 03 Hradec Králové, Czech Republic, Drnovský Pavel
Published: March 2023

The results of magnetometer measurements carried out in small-sized fortifications of the High Middle Ages are presented. In most cases these fortifications were partly or completely abandoned sites. At all sites, structures of anthropogenic origin were discovered. Thanks to the survey various components of residences were identified: internal buildings, fortifications, moats, ramparts. The survey method chosen proved to be suitable for detecting most parts of the 14th to 15th century residences of the petty nobility, particularly in regions with prevailing earthen and wooden architecture. Archaeological structures were detected by way of the survey measurements even at seemingly completely destroyed sites. However, the results of such a magnetometer survey need to be supplemented by other methods of geophysical and archaeological survey.
