b-more-incomplete and b-more positive: Insights on A Robust Estimator of Magnitude Distribution
Authors: Lippiello Eugenio , Petrillo Giuseppe
Published: March 2023

The $b$-value in earthquake magnitude-frequency distribution
quantifies the relative frequency of large versus small earthquakes.
Monitoring its evolution could provide fundamental insights into
temporal variations of stress on different fault patches. However,
genuine $b$-value changes are often difficult to distinguish from
artificial ones induced by temporal variations of the detection
threshold.A highly innovative and effective solution to this issue has recently
been proposed by van der Elst (2021) through the b-positive method,
which is based on analyzing only the positive differences in magnitude
between successive earthquakes.Here, we provide support to the robustness of the method, largely
unaffected by detection issues due to the properties of conditional
probability. However, we show that the b-positive method becomes less
efficient when earthquakes below the threshold are reported, leading to
the paradoxical behavior that it is more efficient when the catalog is
more incomplete. Thus, we propose the b-more-incomplete method, where
the b-method is applied only after artificially filtering the
instrumental catalog to be more incomplete. We also present other
modifications of the b-method, such as the b-more-positive method, and
demonstrate when these approaches can be efficient in managing
time-independent incompleteness present when the seismic network is
sparse.We provide analytical and numerical results and apply the methods to
fore-mainshock sequences investigated by van der Elst (2021) for
validation. The results support the observed small changes in
$b$-value as genuine foreshock features.
The nonlocal impacts of Antarctic subglacial runoff
Authors: Goldberg Daniel N , Twelves Andrew G , Holland Paul Richard , Wearing Martin Graeme
Published: March 2023

Little is known about Antarctic subglacial hydrology, but based on
modeling, theory and indirect observations it is thought that subglacial
runoff enhances submarine melt locally through buoyancy effects.
However, no studies to date have examined effects of runoff on sea ice
and circulation on the continental shelf. Here we use modeled and
observational estimates of runoff to force a regional model of the
Amundsen Sea Embayment. We find that runoff enhances melt locally (i.e.
within the ice-shelf cavity), increasing melt at Thwaites ice shelf by
up to 15 Gt/a given estimates of steady runoff, and up to 25 Gt/a if
runoff is episodic as remote sensing measurements suggest. However
runoff also has smaller nonlocal effects through freshwater influence on
flow and stratification. We further find that runoff reduces summer
sea-ice volume over the continental shelf (by up to 10\%
with steady runoff but over 30\% with episodic runoff).
Furthermore runoff is much more effective at reducing sea ice than an
equivalent volume of ice-shelf meltwater – due in part to the latent
heat loss associated with submarine melting. Results suggest that runoff
may play an important role in continental shelf dynamics, despite runoff
flux being small relative to ice-shelf melting – and that runoff-driven
melt and circulation may be an important process missing from regional
Antarctic ocean models.
Defining Mesoscale Eddies Boundaries from In-situ Data and a Theoretical Framework
Authors: Barabinot Yan , Speich Sabrina , Carton Xavier J.
Published: March 2023

Mesoscale eddies are found throughout the global ocean. Generally, they
are referred to as “coherent” structures because they are organized
rotating fluid elements that propagate within the ocean and have a long
lifetime. Since in situ observations of the ocean are very rare, eddies
have been characterized primarily from satellite observations or by
relatively idealized approaches of geophysical fluid dynamics. Satellite
observations provide access to only a limited number of surface features
and exclusively for structures with a fingerprint on surface properties.
Observations of the vertical sections of ocean eddies are rare.
Therefore, important eddy properties, such as eddy transports or the
characterization of eddy “coherence”, have typically been approximated
by simple assumptions or by applying various criteria based on their
velocity field or thermohaline properties. In this study, which is based
on high-resolution in-situ data collection from the EUREC4A-OA field
experiment, we show that Ertel potential vorticity is very appropriate
to accurately identify the eddy core and its boundaries. This study
provides evidence that the eddy boundaries are relatively intense and
intimately related to both the presence of a different water mass in the
eddy core from the background and to the isopycnal steepening caused by
the volume of the eddy. We also provide a theoretical framework to
examine their orders of magnitude and define an upper bound for the
proposed definition of the eddy boundary. The results suggest that the
eddy boundary is not a well-defined material boundary but rather a
frontal region subject to instabilities.
Extended eigenvalues of a closed linear operator
Authors: Ammar Aymen , Boutaf Fatima , Jeribi Aref
Published: March 2023

A complex number ? is an extended eigenvalue of an operator A if there is a
nonzero operator B such that = ?BA. In this case, B is said to be an
eigenoperator. This research paper is devoted to the investigation of some
results of extended eigenvalues for a closed linear operator on a complex
Banach space. The obtained results are explored in terms two cases bounded,
and closed eigenoperators. In addition, the notion of extended eigenvalues
for a 2 ? 2 upper triangular operator matrix is introduced and some of its
properties are displayed.
A class of integral operators induced by harmonic Bergman-Besov kernels on Lebesgue classes
Authors: Doğan Ömer
Published: March 2023

We provide a full characterization in terms of the six parameters involved
the boundedness of all standard weighted integral operators induced by
harmonic Bergman-Besov kernels acting between different Lebesgue classes
with standard weights on the unit ball of Rn. These operators in some sense
generalize the harmonic Bergman-Besov projections. To obtain the necessity
conditions, we use a technique that heavily depends on the precise inclusion
relations between harmonic Bergman-Besov and weighted Bloch spaces on the
unit ball. This fruitful technique is new. It has been used first with
holomorphic Bergman-Besov kernels by Kaptano?lu and ?reyen. Methods of
the sufficiency proofs we employ are Schur tests or H?lder or Minkowski
type inequalities which also make use of estimates of Forelli-Rudin type
integrals.
Β-matrices and β-tensors
Authors: Orera H. , Peña J.M.
Published: March 2023

In this manuscript we introduce the class of ?-matrices, which gives a new
sufficient condition for the positivity of the determinant. However, we show
that nonnegative ?-matrices are not necessarily P-matrices. For column
stochastic matrices, the property of being a ?-matrix is weaker than strict
diagonal dominance. We extend ?-matrices to tensors and call them ?-tensors.
Although they are not in general P-tensors, we prove that nonnegative
?-tensors of odd order are P-tensors

In this paper, we study additive properties of the generalized Drazin inverse
in a Banach algebra. We first show that a + b ? Ad under the condition that
a, b ? Ad, aba? = ?a?bab?a?, and then give some explicit expressions for the
generalized Drazin inverse of the sum a+b under some weaker conditions than
those used in the previous papers. Some known results are extended.

In this paper, we establish some new results for H?lder continuity of
solutions to vector variational inequalities which model vector network
equilibrium problems with a polyhedral ordering cone under parametric
perturbations. Especially, our approach of studying H?lder continuous
behaviour is employed by the properties of the regularized gap function
based on the ordering cone generated by a matrix.

Glucose-Activated Switch Regulating Insulin Analog Secretion Enables Long-term Precise Glucose Control in Mice With Type 1 Diabetes
Authors: Xie Lifang , Lu Wanling , Zhang Yanhan , Deng Lu , Liu Ming , Gao Hong , Xie Chunguang , Wang Gang
Published: March 2023

Genetic modification of non–β-cells to produce insulin is a promising therapeutic strategy for type 1 diabetes; however, it is associated with issues, including biosafety and precise regulation of insulin supply. In this study, a glucose-activated single-strand insulin analog (SIA) switch (GAIS) was constructed to achieve repeatable pulse activation of SIA secretion in response to hyperglycemia. In the GAIS system, the conditional aggregation domain–furin cleavage sequence–SIA fusion protein was encoded by the intramuscularly delivered plasmid and temporarily kept in the endoplasmic reticulum (ER) because it binds to the GRP78 protein; then, upon hyperglycemia, the SIA was released and secreted into the blood. In vitro and in vivo experiments systematically demonstrated the effects of the GAIS system, including glucose-activated and repeatable SIA secretion, long-term precise blood glucose control, recovered HbA1c levels, improved glucose tolerance, and ameliorated oxidative stress. Additionally, this system offers sufficient biosafety, as evidenced by the assays of immunological and inflammatory safety, ER stress, and histological evaluation. Compared with the viral delivery/expression system, the ex vivo implantation of engineered cells, and the exogenous inducer system, the GAIS system combines the advantages of biosafety, effectiveness, persistence, precision, and convenience, providing therapeutic potential for the treatment of type 1 diabetes.

Article Highlights

We undertook this study to establish a glucose-responsive single-strand insulin analog (SIA) self-supply system in vivo. We sought to determine whether the endoplasmic reticulum (ER) can serve as a safe and temporary repository to store designed fusion proteins and release SIAs under hyperglycemic conditions for efficient blood glucose regulation. The intramuscularly expressed plasmid-encoded conditional aggregation domain–furin cleavage sequence–SIA fusion protein can be temporarily stored in the ER, and the SIA can be released under the stimulation of hyperglycemia, resulting in efficient and long-term regulation of stable blood glucose in mice with type 1 diabetes (T1D). The glucose-activated SIA switch system provides applicable potential for T1D therapy, integrating regulation and monitoring of blood glucose levels.

The transcriptional activity of Pdx1 is modulated by a diverse array of coregulatory factors that govern chromatin accessibility, histone modifications, and nucleosome distribution. We previously identified the Chd4 subunit of the nucleosome remodeling and deacetylase complex as a Pdx1-interacting factor. To identify how loss of Chd4 impacts glucose homeostasis and gene expression programs in β-cells in vivo, we generated an inducible β-cell–specific Chd4 knockout mouse model. Removal of Chd4 from mature islet β-cells rendered mutant animals glucose intolerant, in part due to defects in insulin secretion. We observed an increased ratio of immature-to-mature insulin granules in Chd4-deficient β-cells that correlated with elevated levels of proinsulin both within isolated islets and from plasma following glucose stimulation in vivo. RNA sequencing and assay for transposase-accessible chromatin with sequencing showed that lineage-labeled Chd4-deficient β-cells have alterations in chromatin accessibility and altered expression of genes critical for β-cell function, including MafA, Slc2a2, Chga, and Chgb. Knockdown of CHD4 from a human β-cell line revealed similar defects in insulin secretion and alterations in several β-cell–enriched gene targets. These results illustrate how critical Chd4 activities are in controlling genes essential for maintaining β-cell function.

Article Highlights

Pdx1–Chd4 interactions were previously shown to be compromised in β-cells from human donors with type 2 diabetes. β-Cell–specific removal of Chd4 impairs insulin secretion and leads to glucose intolerance in mice. Expression of key β-cell functional genes and chromatin accessibility are compromised in Chd4-deficient β-cells. Chromatin remodeling activities enacted by Chd4 are essential for β-cell function under normal physiological conditions.

Numerical and experimental studies of aeroelastic hinged wingtips
Authors:   , Balatti Davide
Published: March 2023

Aeroelasticity is the science that investigates the mutual interaction between aerody-namic, elastic, and inertia forces and how this affects the static and dynamic structural response. Aeroelastic models can be defined considering different levels of fidelity de-pending on the models’ aim. Gust loads are among the most critical cases an aircraft can encounter, and so mitigating the loads enables the design of a lighter structure, consequently reducing production and fuel consumption costs. Hinged wingtips have shown potential to improve the wing aerodynamic performance while alleviating struc-tural loads. The aim of this work is the numerical and experimental study of aeroelastic wings with hinged wingtips subjected to gusts. Measurements from wind tunnel tests are used to validate the numerical model. Two numerical models, representative of the same aircraft with hinged wingtips subjected to gusts, were considered, a detailed and a simplified one. The latter model, due to its low number of degrees of freedom, was used for wingtip design optimisation. Gust and turbulence events cannot be measured di-rectly, but they can be identified from in-flight measurements. Cubic B-spline functions were used for gust identification considering simulated flight data from the simplified and detailed models. Results have shown the ability of the simplified model to identify the gust and turbulence considering simulated data from the detailed model. To validate the numerical models, a gust generator was designed, installed and commissioned for the Swansea University wind tunnel. Experimental results have shown the difficulty of creating a perfect ‘1-cos’ gust at the desired location. Two techniques to improve the ‘1-cos’ gust were considered. In the first case, the transfer function between the vane rotation and the gust produced at the aircraft model location was identified, and its in-verse was used to calculate the vane rotation. The improvements using this approach are limited by the strong nonlinearity of the aerodynamics. A parametric study of the vane rotation has shown that a more complicated vane rotation function allows ‘1-cos’ gusts at the aircraft model location to be obtained with a mean square error two orders of magnitude smaller than the initial case. An elastic wing able to accommodate different wingtips was manufactured. Three wingtips, namely a fixed wingtip, a hinged wingtip, and a hinged wingtip with a torsional spring at the hinge were considered. Static and dynamic wind tunnel tests have shown the potential of hinged wingtips in reducing wing gust loads. Measured gust loads were used to validate the aeroelastic models.
Perovskite Interlayers For Mass Manufacture Using Roll-To-Roll Compatible Deposition Methods
Authors:   , Richards David
Published: March 2023

Organic-inorganic perovskites have been used as the light absorbing layer in solar cells since 2009 and have since seen a ground breaking rise in efﬁciency in a relatively short period of time. Today, perovskite based solar cells have reached efﬁciencies of over 24% making them a potential competitor to conventional solar cells such as silicon. However, unlike silicon, per-ovskites can essentially be "printed" as the layers can all be solution processed and prepared at low temperatures, giving them a huge advantage in terms of cost and process-ability. Nonethe-less, before perovskites are commercially viable, signiﬁcant work must be undertaken to ensure they are ready for mass manufacture. This work was aimed at developing large scale compat-ible (roll-to-roll), ﬂexible perovskite solar cells utilising an Indium doped Tin Oxide (ITO) coated PET substrate. Due to the nature of the substrate, the processing temperatures of each layer had to be low and ideally less than 150 °C. Signiﬁcant work has been undertaken to make perovskite layers roll-to-roll compatible, but the interlayers which it is sandwiched between require further investigation. Therefore, the following work presents the development and ap-plication of a roll-to-roll compatible electron transport layer (ETL) and hole transport layer (HTL). For the deposition of each layer in a roll-to-roll setting, slot-die coating was employed due to its compatibility with solution deposition and small material wastage. In addition, care was taken to focus on low-toxicity alternatives removing barriers that would otherwise be in place for toxic substances which would hinder large scale manufacturing from a health and safety point of view.

Published: March 2023

Poverty is a complex problem that has an impact on various social problems such as education, unemployment, health and economic growth. Therefore, the problem of poverty is important to overcome in order to create population welfare. One of the analyses that can be used to model the percentage of poverty is regression analysis. Regression analysis is divided into two approaches, namely parametric and nonparametric. Parametric regression has several assumptions while, the only assumption nonparametric regression shape of the curve does not form a certain pattern. There are several approaches to nonparametric regression, one of which is the Fourier Series. The purpose of this study is to model the percentage of poverty in West Sumatra Province. The unclear shape of the curve in the data used is a consideration for using nonparametric regression. Then it is known that the data used in this study is data per region which tends to have a fluctuating nature. So it is suitable to use the Fourier series approach. In this research, nonparametric regression modeling with one, two, and three oscillation parameters was attempted. The best model was obtained which consisted of two oscillation parameters with a Generalized Cross Validation (GCV) value of 2.110 and R² of 92.44%.
Impact of substance-related harms on injury hospitalizations in Canada, from 2010 to 2020
Authors: Toigo Stephanie , McFaull Steven R. , Thompson Wendy
Published: March 2023

Introduction

Injuries continue to be a leading cause of death and contribute significantly to hospitalizations each year in Canada. Substance use has been associated with an increase in intentional and unintentional injuries, resulting in hospitalizations. This study examines trends in injury hospitalizations with a co-occurring substance diagnosis, to quantify the burden of injuries and identify at risk populations.

Methods

We analyzed Discharge Abstract Database data between 2010/11 and 2020/21, for clinical and demographic information about hospital discharges across Canada. We used ICD-10 codes to identify injury hospitalizations with co-occurring substance diagnostic codes, by injury intent and substance type. Rates, proportions, age-specific rates and age-standardized rates were calculated, trends quantified using average annual percent change and results stratified by sex and age group.

Results

From 2010/11 to 2020/21, unintentional injuries accounted for over half of all substance-related injury hospitalizations. Substance-related injuries accounted for 12% of total injury hospitalizations over this period. Overall, substance-related injury hospitalizations with co-occurring use of stimulants, opioids, cannabinoids and alcohol increased significantly among males and females. Unintentional substance-related, injury hospitalizations were more common later in life, and intentional substancerelated injuries were more common among adolescents and young adults.

Conclusion

These results highlight key demographic groups with higher rates of substance-related injury hospitalizations that would benefit from targeted prevention efforts.

Published: March 2023

Introduction

Since 2015, there has been growing interest in Canada and beyond on the benefits of outdoor play for physical, emotional, social and environmental health, wellbeing and development, for adults as well as children and youth.

Methods

This scoping review aims to answer the question, “How, and in what context, is adult-oriented outdoor play being studied in Canada?” We conducted an electronic search for peer-reviewed articles on outdoor play published in English or French after September 2015 by authors from Canadian institutions or about Canadian adults. The 224 retrieved articles were organized according to eight priorities: health, well-being and development; outdoor play environments; safety and outdoor play; cross-sectoral connections; equity, diversity and inclusion; professional development; Indigenous Peoples and land-based outdoor play; and COVID-19. We tallied the study designs and measurement methods used.

Results

The most common priority was outdoor play environments; the least common were COVID-19 and Indigenous Peoples and land-based outdoor play. Cross-sectional studies were the most common; no rapid reviews were identified. Sample sizes varied from one auto-ethnographic reflection to 147 000 zoo visitor datapoints. More studies used subjective than objective measurement methods. Environmental health was the most common outcome and mental/emotional development was the least.

Conclusion

There has been a staggering amount of articles published on adult-oriented outdoor play in Canada since 2015. Knowledge gaps remain in the relationship between outdoor play and adult mental/emotional development; the connections between environmental health and Indigenous cultures and traditions; and how to balance promoting outdoor unstructured play with protecting and preserving natural spaces.

Synthèse iconographique et liturgique d’un sujet d’art dévotionnel occidental, accepté dans la sphère roumaine dès la seconde moitié du XVIIe siècle par la médiation de l’iconographie baroque ukrainienne, l’icône reflète l’inculturation du thème eucharistique du Christ la Vigne dans la spiritualité orientale roumaine.
Născuți din coasta străpunsă. Observații asupra temei Cristos Vița de Vie pornind de la o icoană românească pe sticlă de secol XIX. Având ca punct de plecare reprezentarea iconografică a temei Cristos Vița de Vie într-o icoană românească de secol XIX din satul transilvănean Șercaia (Făgăraș), acest studiu cercetează originile reprezentării motivului iconografic al viței de vie asociat cu reprezentarea figurii lui Isus Cristos în prima iconografie creștină, apoi cele mai semnificative trimiteri biblice și patristice, precum și inovațiile în reprezentarea motivului iconografic Cristos Vița de Vie în iconografia medievală timpurie și în perioada succesivă, pentru a stărui apoi asupra analizei detaliate a specificității reprezentării iconografice în icoana din Șercaia. Icoana se dovedește a fi o sinteză iconografică și liturgică a unei teme iconografice prezente în arta devoțională occidentală, temă pătrunsă în mediul românesc deja din a doua jumătate a secolului al XVII-lea prin mijlocirea iconografiei baroce ucrainene. Varianta românească nu transpune repetitiv interpretarea iconografică a artei apusene, ci exprimă o adevărată inculturare în mediul cultural românesc a temei euharistice a lui Cristos Vița de Vie, filtrată prin specificul spiritualității orientale românești.
Cuvinte-cheie: Cristos Vița de Vie, Om al durerilor, iconografia paleocreștină, iconografia românească de secol XIX, inculturare iconografică.

Carbon dioxide (CO2) is one of the greenhouse gases that causes global warming with the highest concentration in the atmosphere. Mangrove forests can absorb CO2 three times higher than terrestrial forests and tropical rainforests. Moreover, mangrove forests can be a source of Indonesian income in the form of a blue economy, therefore an accurate method is needed to investigates mangrove carbon stock. Utilization of remote sensing data with the results of the above-ground carbon (AGC) detection model of mangrove forests based on multispectral imaging and vegetation index, can be a solution to get fast, cheap, and accurate information related to AGC estimation. This study aimed to investigates the best model for estimating the AGC of mangroves using Sentinel-2 imagery in Benoa Bay, Bali Province. The random forest (RF) method was used to classified the difference between mangrove and non-mangrove with the treatment of several parameters. Furthermore, a semi-empirical approach was used to assessed and map the AGC of mangroves. Allometric equations were used to calculated and produced AGC per species. Moreover, the model was built with linear regression equations for one variable x, and multiple regression equations for more than one x variable. Root Mean Square Error (RMSE) was used to assess the validation of the model results. The results of the mangrove forests area detected in the research location around 1134.92 ha, with an Overall Accuracy (OA) of 0.984 and a kappa coefficient of 0.961. This study highlights that the best model was the combination of IRECI and TRVI vegetation indices (RMSE: 11.09 Mg/ha) for a model based on red edge bands. Meanwhile, the best results from the model that does not use the red edge band were the combination of TRVI and DVI vegetation indices (RMSE: 13.63 Mg/ha). The use of red edge and NIR bands is highly recommended in building the AGC model of mangrove forests because they can increase the accuracy value. Thus, the results of this study are highly recommended in estimating the AGC of mangrove forests, because it has been proven to be able to increase the accuracy value of previous studies using optical images.

Peculiarities of determining the morphogenesis of plants Corylus avellana L. and Prunus dulcis (Mill.) D.A.Webb in vitro culture

The purpose of the research was to identify the physiological–biochemical and anatomical–morphological peculiarities found during in vitro cultivation of Corylus avellana L. and Prunus dulcis (Mill.) D.A.Webb, which occur as a result of the action of trophic and phytohormonal determinants. The research was conducted on three hazelnut varieties (Trapezund, Jefferson, Tonda Gentile Romana) and four almond varieties (E5 Borozan, M41 Alex, Georgia, Louise). A theoretical and experimental rationale for their use in the microclonal propagation of these cultures has been developed. The effectiveness of the preparatory stage before introduction into aseptic conditions for growing mother plants in closed soil conditions with scattered artificial lighting and microbiological protection has been proven. This reduced self-intoxication by oxidation products with phenol-like substances and microflora contamination of primary explants. Among the nutrient media compared, the best was Nas and Read (NRM) for hazelnuts and Nas Almond Medium (NAM) for almonds. Passaging on the same media leads to a decrease in regeneration indicators. In regenerants of almonds, the rosette of the shoots was noted, and in hazelnuts, the death of apical buds was also found. To prevent this, alternating NRM and driver and kuniyuki walnut (DKW) media for hazelnuts and NAM and Quirin and Lepoivre (QL) for almonds was effective. Long-term cultivation on media with a high content of synthetic analogues of phytohormones leads to the accumulation of phytotoxic effects with each subsequent passage. The phytotoxic effect of cytokinins was manifested in hyperhydration of shoots and of auxins in callus fertilisation. On comparing the ontogenesis of regenerants from explants isolated from mother plants aged 30–180 days, it was found that the optimal age for hazelnut and almond was 90 days. To reset the trophic and hormonal determinants, the introduction of explant donors into a state of dormancy has been successfully used. At the final fourth stage of microclonal propagation, in order to adapt plants simultaneously with an increase in the number of regenerants, it is effective to use the photoautotrophic method of microclonal propagation with intensive lighting and air enriched with carbon dioxide. For the transition of plants from conventional heterotrophic propagation to autotrophic cultivation, an intermediate stage of pre-adaptation of regenerants in wet chamber conditions is effective.

The region of Ain-Témouchent is a seismic zone; its land is predominately agricultural and shows complex structures, with many problems linked to the development of urbanized areas; these problems are directly or indirectly related to the geotechnical conditions of soil.

The purpose of the present research is to build a database from the different measurements carried out in the region, and to conduct tests in places where information is not available in order to consider the entire perimeter of the study area.

Once the database is completed, an analysis of all the data will be carried out using a numerical tool in order to establish the geotechnical map of the city. This map will certainly allow all decision-makers and designers to have clear and precise information when proposing or designing new structures.

The geotechnical mapping of Ain-Temouchent soils based on 178 observations divided these soils into ten groups. Eight of them according to the Unified Soil Classification System (USCS): CH (High plasticity clay), CL (Low plasticity clay), MH (High plasticity silt), ML (Low plasticity silt), SC (clayey sand), SM (Silty sand), GM (Silty gravel with sand), OH (organic soil of high plasticity). The other two groups are rocky soils: basalts (hard volcanic rock with high resistance), and limestone turf (sedimentary rock).
Influence of double cavities on anchors capacity
Authors: NAJI Ali , MUSTĂŢEA Florin-Sebastian
Published: March 2023

Soil is considered an essential component of the factors that are affecting the structures. Due to the problems that are faced under various conditions while the structure is in use, the behavior of the soil is complex. The presence of cavities inside various types of soil, such as gypsum soil and the soil of some old towns, is one of its difficult problems. The formation of these cavities is due to natural and industrial causes, one of the natural causes being the dissolve of salts inside them. As for the industrial one, it is due to the presence of some old buildings. The presence of this type of cavities affects the life of the structures and as a result, it creates cracks in the foundation, therefore reducing the life of the structures.

The unexpected formation of cavities inside the soil was based mainly on some practical experiments for this research. Two cavities have been created inside the soil with different locations from the anchor to study the capacity of the anchor. The results showed that the presence of the cavity affects the capacity of the anchor according to its location from the plate as well as from the rod. The closer the cavity are to the plate; the capacity have been decreased by a certain percentage depending on the distance from the plate anchor.
Abusive Constitutionalism in Hungary
Authors: Juhász Krisztina
Published: March 2023

The study, using the concept of abusive constitutionalism, examines those formal and informal constitutional changes which took place after the Fidesz-KDNP coalition had come into power in 2010 and resulted in the hybridisation of the Hungarian political system. The paper, using qualitative research methods such as analysis of the relevant literature and primary resources, including the in-depth analysis of the relevant Constitutional Court decisions, comes to the conclusion that the Orbán governments first dismantled the checks and balances, foremost the Constitutional Court via formal abusive constitutional changes, and as a next step, with the contribution of the weakened and packed Constitutional Court, the government aims to eliminate the EU’s legislation and intervention on the field of asylum policy via formal and informal abusive constitutional changes based on the concepts of constitutional pluralism and identity.
