Mathematical representation is essential as the gateway to mastering mathematical literacy. This literature study aims to determine the growth of students' mathematical representation abilities in the last three years. This literature study presents a literature review on the development of mathematical representations, including media, strategies, and measurement instruments to serve as the basis for future mathematical representations. The literature study method used is the SLR (Systematic Literature Review), utilizing a review procedure that refers to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework in the period 2020 to 2022 because the growth in literature studies on mathematical representations is very significant and latest. Data were collected by reviewing 24 Scopus-indexed articles and proceedings from the Scopus database. The study's results reveal that from the 24 selected literature, it can be interpreted if the mathematical representation ability can be improved and fulfills the indicators of mathematical representation itself by providing innovation in media, strategies, and instruments in learning mathematics. The innovations provided can be in the form of technology integration (Geogebra), no longer conventional strategies (RME strategy), and instrument indicators of the representation itself. Thus the ability of students' mathematical representations is no longer included in the low category in solving mathematical problems.

Simulation of the Onset turbulent flow around a Isothermal Complex Geometries: an analysis of thermofluid dynamic flow
Authors: Santos Rômulo D. C. , Da Silva Quétila Gaspar , De Lima Tananta Samia Rubi
Published: July 2023

In this work, in the area of Computational Fluid Dynamics (CFD), more specifically in the area of thermofluid dynamics for two-dimensional flows (2D), and also considering, the fluid-body interaction, allied to the phenomena of heat-transfer by mixed convection and the beginning of processes of the turbulent flow phenomenon in the fluid-body interaction, a study is proposed that demonstrates the efficiency in the analysis and simulation of these complex phenomena. We adopt an Eulerian approach for a fixed mesh, which is intended to represent the thermofluid dynamic movement, working together with a Lagrangian mesh, the latter being intended to discretize the immersed body. The strategy, in this work, allows approaching complex isothermal geometries, which present a certain aerodynamic degree on their surface, being popularly known as blunt body, where this, in turn, is immersed in an incompressible Newtonian fluid. One of the contributions of this work is the introduction of a simple but efficient method to calculate the Nusselt number. Regarding the process of validation and modeling of the physical phenomena of interest, that is, regarding the effectiveness of the methodology, called the Immersed Frontier, an implementation with low computational cost was carried out for the transfer of mixed convection heat, as well as for modeling the turbulence, namely, making use of the Spalart-Allmaras model, in the context of the URANS (Unsteady Reynolds Average Navier -Stokes) methodology. Numerical results showed good convergence with data available in the literature, which confirms the numerical precision and reliability of the adopted model.

Published: July 2023

Today there are many Muslim women who wear the hijab, but the existence of the hijab which was originally interpreted as the cover of genitalia turned into a fashion trend. The development of the times has led to the emergence of the creation and innovation of the veil model so that not a few women make the veil as a daily dress. Teenagers who are experiencing periods of self-discovery become one of the targets of the transformation of the hijab model. They switch from the ordinary hijab to the hijab syarâ€™i by reason of following Islamic law or just following fashion trends. In this phase, teenagers are trying to understand what is part of "me" and "not me", or in the world of psychology known as self-concept. Namely the process of someone in knowing and understanding themselves. This is consistent with what was stated by Barthes regarding "the language of fashion" which states that, every form of fashion must contain certain messages that the user wants to convey. Because of this, the researcher tries to find out to what extent a teenager, especially among female students at IAIN Surakarta, who wears a hijab in understanding their own concept through the clothes they wear. Where according to Willey, the self-concept is divided into two, namely positive and negative self-concepts. After knowing the self-concept of sharia hijabi students at IAIN Surakarta, it can also be seen that actions can be taken to foster and direct students to have a good (positive) self-concept. This research was conducted by survey method through the distribution of a questionnaire containing instruments about self-concept (Tennessee Self Concept Scale) developed by William H. Fitts.Keywords: Aurat; Hijab; Hijab Syar'i Trends; Self-concept

Marriage is a spiritual bond between a man and a woman as husband and wife with the aim of forming a happy and everlasting family (household) based on the Godhead. To guarantee legal certainty, a marriage must be legal in both religion and state. In Islam the marriage is said to be valid if it meets the terms and conditions set. This was also stated in KHI Chapter IV, the first part of article 14, stated that the marriage pillar consists of a prospective husband, prospective wife, marriage guardian, two witnesses, consent and qabul. The most important thing that determines whether a marriage is legal or not is a guardian. In one history of the hadith it is stated that marriage without a guardian is null and void. However, there are guardians who refuse to marry their children, even though it is also clear in Surah Al Baqarah verse 232 that guardians must not hinder if the child already has proposed marriage. The actions of the guardian are clearly not in accordance with the verse. As a result of this rejection makes the child does not have a guardian to marry her. This has become the initial problem of a marriage. One of them in the Klaten Religious Court in 2017 has a fairly high number of problems related to guardians who refuse to marry their children. Then the focus of this research is to find out the factors that cause guardians to refuse to marry their children, related to an application submitted to the Klaten Religious Court in 2017. The method used in this research is Field Research with a Qualitative Descriptive approach in which data collection is carried out directly with the judge who decides the case took place in the Klaten Religious Court.Â Keywords: Marriage; Refuse; Cause; Adhal Guardian; Judge Guardian.

This research is a qualitative research to find the meaning of a phenomenon. The data analysis uses the triangulation method, which is to cross check from a document source with another source, or from a document source with a historical fact. These results are (1) Formal educational institutions are the right means in carrying out religious moderation activities because in formal education there is a structured, systemic and easy-to-evaluate learning space, (2) religious moderation learning in non-formal institutions, is very effective in developing insight nationality considering that non-formal educational institutions are built on public awareness and are doctrinal in character, (3) the implementation of religious moderation education in informal educational institutions is also no less strategic considering that informal educational institutions that are integrated in the community can effectively stem radical religious beliefs that easily accessible and consumed by the public.Keywords: Religious Moderation; National Insight; Educational Institutions
Fatigue strength evaluation of case-hardened components combining heat treatment simulation and probabilistic approaches
Authors: Iss Valérian , Meis Jean-André , Rajaei Ali , Hallstedt Bengt , Broeckmann Christoph
Published: July 2023

In order to raise the hardness and strength of the surface layer of
mechanical components and induce favourable residual compressive
stresses, case-hardening procedures have become established in the heat
treatment of steel. In this work, a calculation concept for the fatigue
strength of components that have been case-hardened through carburizing
heat-treatment is being developed. The residual stress and the load
stresses in complex-shaped, carburized materials are determined using a
finite element (FE) model. The fatigue limit of the components is
derived using probabilistic methods and taking into account hardness
gradients, residual stresses, and non-metallic inclusions. The model is
validated with available axial bending fatigue test data and then used
to predict the rotating bending fatigue limit of samples with various
geometries and heat-treatment conditions. This work demonstrates the
capability of combining probabilistic and FE-based modelling to
represent complex interactions between variables that affect the fatigue
of heat-treated components, such as steel cleanliness, notch shape,
case-hardening depth, or loading conditions.
Polarization-dependent nanoantenna array with uniform resonance coverage for broadband surface-enhanced infrared absorption (SEIRA) spectroscopy
Authors: Yu Xia , Ni Jing , Donglai * , Tang Zhouzhuo , Bian Yupei , Feng Yingmei
Published: July 2023

Broadband surface-enhanced infrared absorption (SEIRA) spectroscopy is
crucial for achieving high-sensitivity in the detection of complex
analyte. A new design of Six-pointed Asterisk NanoAntenna (SANA) array
is proposed to enhance signal-to-noise ratio of SEIRA spectroscopy. The
SANA structure offers elevated design freedom in terms of resonance
amplitude and frequency. The measurement data clearly demonstrates that
our device has the most uniform resonance coverage over 390 cm
. The broadband resonance uniformity directly
benefits the signal-to-noise ratio enhancement across six fingerprints
of alanine. Our SEIRA nanoantenna array design method serves as an
effective approach for broadband and dense fingerprints detection. For
example, it enables the simultaneous measurement of amide I and amide
II, allowing for more comprehensive analysis of biomolecules.

application varying from flavouring the food to various medicinal uses.
But the major limitations linked with these nature oriented spicesare
individualized and restricted information about the identification and
quality mapping. With increasing demands, adulteration of spices and
herbs become a major problem for all the stakeholders .
Artificial intelligence based machine learning and deep learning models
have already been implemented in the various ways for the identification
of herbal images in real time basis. Evidence from past studies related
to identification of plants images strengthens our concept for the
implementation of the artificial intelligence in the spice sector for
the adulteration identification which can become pioneer step in solving
the problem of adulteration. There are various opportunities for
advancement in producing a robust model for the identification of spices
accurately in real time basis. In this review paper, various reliable
and efficient machine learning algorithms for herbs and spice image
classification has been reviewed. Techniques involved forpreparation of
such model have been discussed in details for the better understanding
of readers. With inclusion of various globally available herbal image
datasets and review of recent research related to plants image
identification through machine learning, this article also explains
various machine learning model such as artificial neural network,
convolutional neural network etc along with different parameters
involved in the authentication of the developed model to devise an
artificial intelligence based methodology for quality assessment of
herbs and spices.

therapy-based trials for advanced the field and created new standards of
care across a wide spectrum of pediatric cancer diagnoses. Key findings
include that tandem autologous transplant improved survival for patients
with neuroblastoma and atypical teratoid/rhabdoid brain tumors, one
umbilical cord blood (UCB) donor was safer than two UCB donors, killer
immunoglobulin receptor (KIR) mismatched donors did not improve survival
for pediatric acute myeloid leukemia when in vivo T cell
depletion is used and the depth of remission as measured by
next-generation sequencing based minimal residual disease assessment
pre-transplant was the best predictor of relapse for acute lymphoblastic
leukemia. Plans for the next decade include optimizing donor selection
for transplants for acute leukemia/myelodysplastic syndrome, using novel
engineered cellular therapies to target a wide array of malignancies,
and developing better treatments for cellular therapy toxicities such as

Authors: Grattan C E , Carmichael A J , Shuttleworth G J , Foulds I S
Published: July 2023

Topical PUVA was compared with UVA for the treatment of chronic vesicular hand eczema in a double-blind randomized within-patient trial. Twelve of 15 patients completed 8 weeks' treatment and were followed up for 8 weeks. Both sides improved over the 8-week treatment period (p less than 0.05) and both remained substantially better objectively and subjectively at 8 weeks' follow-up. There was no statistical difference between assessments of the treated hands at any stage. Nine of the patients who completed the study answered a questionnaire up to 18 months later. In 4, eczema was healed, 3 were better on the PUVA-treated hand and 1 on the UVA-treated hand. It is possible that UVA alone is beneficial for chronic hand eczema.
The relation between seborrheic keratoses and malignant solid tumours. A case-control study.

Published: July 2023

In order to establish whether or not here is an association between cancer and intense growth of seborrheic keratosis, the so-called Leser-Trelat sign, we conducted a case control study in which the number and features of seborrheic keratosis in 82 patients with recent solid tumours, were compared with 82 age- and sex-matched controls. Neither numbers nor features of seborrheic keratosis differed significantly in patients and controls. Eruptive seborrheic keratosis was noted in only one patient and one control. This study showed that solid malignancies are not generally associated with an increase in the number or size of seborrheic keratosis lesions, thus suggesting that they are not controlled by a hypothetical secretion of growth factors by tumours. Our results suggest that Leser-Trelat is either a coincidence, or at most a very rare sign of unusual types of cancer. We also showed that multiple cherry angiomas, previously reported to be a paraneoplastic sign, are not regularly associated with solid tumours.
Nocturnal growth hormone release in children with short stature and atopic dermatitis.
Authors: David T J , Ferguson A P , Newton R W
Published: July 2023

This study was designed to test the hypothesis that children with atopic dermatitis and short stature fail to release growth hormone after falling asleep. Peak serum growth hormone response to arginine was compared with peak growth hormone concentration during sleep in 6 children with atopic dermatitis and short stature (greater than 3 SD below the mean) aged 7 to 12 years, and 5 control children aged 9 to 12 years without atopic dermatitis or asthma but with unexplained short stature (greater than 3 SD below the mean). All 5 control children achieved normal levels of growth hormone after falling asleep, whereas 3 of the 6 children with dermatitis did not. All patients with dermatitis were capable of releasing growth hormone after arginine stimulation. The results suggest that in some prepubertal children with atopic dermatitis and short stature there may be an impairment of growth hormone release during stage 4 sleep.
UVB irradiation induces lipid peroxidation and reduces antioxidant enzyme activities in human keratinocytes in vitro.
Authors: Punnonen K , Puntala A , Jansén C T , Ahotupa M
Published: July 2023

Exposure of human keratinocytes to UVB irradiation resulted in formation of conjugated double bonds and thiobarbituric acid reactive material. The activities of superoxide dismutase and catalase, enzymes which protect cells against oxidative damage, were concomitantly reduced. The present study suggests that in keratinocytes, exposure to UVB irradiation leads to a chain of events resulting in lipid peroxidation reactions accompanied by an impairment of the cellular defence system against reactive oxygen species. These phenomena may act synergistically in UVB-induced cutaneous pathological processes, such as carcinogenesis.

Eczema craquelé can be induced by repeated open application of a topical glucocorticoid, viz. 0.05% clobetasole 17-propionate cream. This might not be invariably due to the active component. Comparison of the skin surface roughness as assessed by profilometry and as expressed by RZDIN showed a decrease after repeated open application of 0.1% betamethasone 17-valerate cream and 0.25% prednicarbate cream, but an increase following the vehicle of the latter preparation. Thus commercial oil-in-water emulsion preparations seem to be potentially injurious to human skin, though this may be masked when a glucocorticoid is added.
A case report of acute febril neutrophilic dermatosis (Sweet's syndrome) and Crohn's disease.

Published: July 2023

A case of Crohn's disease complicated by Sweet's syndrome is presented. The main ultrastructural findings were the multiplication of basal lamina surrounding the venulea, interendothelial gaps and in perivascular locations mixed infiltrates of neutrophiles and erythrocytes. The changes indicate that the initial site of the reaction was the walls of the dermal vessels.
Elastolysis in lichen ruber planus.
Authors: Dahlbäck K , Sakai L Y
Published: July 2023

The dermal elastic fiber network was studied in specimens from five patients with lichen ruber planus, using a standard elastin staining procedure (orcein), results being compared with those for the elastin-associated microfibrillar network stained using anti-fibrillin antibodies in an immunofluorescence and an avidin-biotin-peroxidase complex technique. Additional specimens of healed apparently normal skin were taken from two of the patients. Orcein-stained fibers were scarce or absent in the inflammatory zone in all the lesions. In contrast, an extensive fibrillin immunoreactive network was present in the papillary zone in all the specimens, in a pattern similar to that of normal skin. In specimens from healed lesions of lichen ruber planus, dermal orcein-stained fibers were present in the papillary dermis. The findings indicate that the amorphous component of elastic fibers is destroyed during the acute phase of lichen ruber planus. Hypothetically, the elastolysis is caused by elastases released from macrophages known to be present in the lichenoid infiltrate. In contrast, the fibrillin fiber network seems to be less or not at all affected by proteolytic events during the inflammatory phase of lichen ruber planus.

The distribution and density of tryptase- and chymase-positive mast cells in lesional and non-lesional cutaneous lichen planus (LP) was analysed. For this, enzyme-histochemical staining techniques and morphometrical measurements were applied. In non-lesional LP skin, chymase-positive cells (TC mast cells) showed a distribution similar to that found in both non-lesional psoriatic skin and in normal skin. Tryptase-positive cells (reflecting both T and TC mast cells), however, were increased in number in the upper dermis of non-lesional LP skin. In lesional LP skin, there were fewer chymase-positive cells in the upper dermis, whereas there were more tryptase-positive cells. In the upper dermis, no differences in the number of tryptase containing cells were detected between lesional and nonlesional LP skin. In lesions of LP and psoriasis, tryptase-positive mast cells are increased but differ in their distribution in the papillary dermis. In psoriatic lesions, tryptase-positive cells are frequently observed in epidermal contact, a feature very rarely seen in LP lesions. The present results suggest that the increased numbers of T mast cells in the upper dermis of nonlesional LP skin may be involved in initiating the LP lesion. It seems unlikely that mast cells could be responsible for the epidermal basal cell damage, though T mast cells do participate in the general inflammatory reaction.
Production of interleukin-2 by mononuclear cells in vitro in patients with atopic dermatitis and psoriasis. Comparison with serum interleukin-2 receptor levels.

Atopic dermatitis is associated with profound immunological alterations, in particular decreased lymphoproliferative responses upon stimulation with T-cell mitogens. T-cell blastogenesis involves the production of the soluble cytokine interleukin-2 (IL-2), which in turn upregulates the expression of its own receptor. To investigate the potential role of this cytokine for the pathomechanisms present in atopic dermatitis, 24-h supernatants of PHA-stimulated peripheral blood mononuclear cells from patients with atopic dermatitis (n = 30) of a moderate to severe disease activity were tested for IL-2 activity. In addition, serum concentrations of soluble interleukin-2 receptor (IL-2R) were measured. Non-atopic healthy controls (n = 19) and patients with psoriasis (n = 20), an inflammatory skin disorder with distinct pathogenesis, served as controls. In comparison with psoriasis patients and normal controls, PHA-stimulated mononuclear cells of atopic dermatitis patients released significantly less IL-2 into supernatants. Moreover, there was an inverse correlation between IL-2 concentrations and body surface involvement or serum IgE levels. In contrast, serum IL-2R levels were significantly elevated in both atopic dermatitis and psoriasis, as compared with healthy controls. Furthermore, IL-2R levels in atopic dermatitis patients showed a significant correlation with IgE levels and body surface involvement. The data indicate that T cell activation may occur in both skin diseases. Atopic dermatitis, however, is further characterized by the decreased capacity of mononuclear cells to release IL-2 upon stimulation in vitro.
Lupus anticoagulant and the skin. A longterm follow-up study of SLE patients with special reference to histopathological findings.

Published: July 2023

Skin manifestations were described in lupus anticoagulant (LA) positive and in LA negative SLE patients. Necrotic ulcers appearing at the beginning of the disease process characterized the 33 LA positive patients. Thirteen patients had a "peripheral vascular syndrome" small leg ulcers of livedoid vasculitis type following deep venous thromboses, in 3 patients developing into pyoderma gangrenosum like ulcers and in 2 patients into pseudo-sarcoma Kaposi. The lesions were histologically characterized by capillary angiogenesis with extravasated red blood cells, sparse inflammatory cell infiltrates and microthromboses. Three patients had ulcers clinically and histologically resembling those seen in Degos' disease. Five patients had anetoderma showing elastic tissue depletion and microthromboses histologically. A different pattern of skin changes was seen in the LA negative patients. Our findings suggest that antiphospholipid antibodies play a pathogenetic role in the described skin manifestations of LA positive SLE patients.
Porokeratosis with large skin lesions. Histologic, cytologic and cytogenetic study of three cases.
Authors: Otsuka F , Watanabe R , Kawashima M , Tomita Y , Ohara K , Ishibashi Y
Published: July 2023

Three porokeratosis patients with large skin lesion(s) are reported. The histopathology of the large lesions revealed that the epidermis 1) frequently presented slight or marked acanthosis and/or elongation of the rete ridge, and 2) contained abnormal cells, e.g. hyperchromatic, large, multinucleated, and/or irregular shaped nuclei. The DAPI-DNA microfluorometric study revealed DNA polyploidy and/or an increased population of epidermal cells with hyperdiploid and/or tetraploid DNA content. These results indicate the proliferating potential of the epidermis and the existence of a neoplastic clone or clones therein. This finding may explain the enlargement of skin lesions and possibly the development of malignancy, as sometimes occurs in large skin lesions. Furthermore, cultured skin fibroblasts from a patient's skin lesion or its surrounding skin revealed various kinds of chromosomal structural abnormalities, which may serve as a basis for the development of abnormal neoplastic clones in the porokeratotic epidermis.
Simultaneous assessment of blood flow in UVB-inflamed human skin by laser Doppler flowmetry and the 133-xenon washout technique.
Authors: Petersen L J , Kristensen J K
Published: July 2023

The purpose of the study was to compare skin blood flow by laser Doppler flowmetry (LDF) and the 133-Xenon washout technique in UVB-inflamed human skin. Six healthy subjects participated in the study. Forearm skin blood flow was measured prior to irradiation and then 8, 24, 48 and 72 h after the exposure to twice the minimal erythema dose of UVB. Baseline blood flow as measured by the 133-Xenon washout method was 5.2 (range 3.0 to 10.4) ml/100g/min and LDF flux was 3.1 (range 2.7 to 5.7) arbitrary units. Following irradiation, maximum blood flow increase as evaluated by the 133-Xenon washout was 10.8 (95% confidence interval 3.7 to 11.3) times baseline blood flow, corresponding to an absolute blood flow of 47.5 (range 33.8 to 56.3) ml/100g/min. Maximum increase after induction of inflammation as assessed by LDF was 34.6 (95% confidence interval 24.6 to 56.5) times baseline flux. The two methods showed comparable time courses in all subjects. A significant correlation between the two methods was found, Spearman's rho = 0.54, p = 0.006. The relative LDF blood flow increase was 4.2-fold (95% confidence interval 2.7 to 5.0) greater than the increase measured by the 133-Xenon washout method. These results are at variance with previous comparative studies of the two methods. Some explanations are discussed.
Peptide T a new treatment for psoriasis? A study of nine patients.
Authors: Marcusson J A , Talme T , Wetterberg L , Johansson O
Published: July 2023

Nine patients with recalcitrant and long-standing psoriasis were treated over a period of 28 days with 2 mg Peptide T iv, once daily (22-34 micrograms/kg bodyweight). Eight of them showed an improvement of less than 50% by day 28 and one deteriorated. The patients were evaluated for a further 3 months when no topical or systemic treatment was given. Five patients recovered by more than 50%, during the months following termination of the therapy. Two patterns of healing were noted: firstly, a steady clearance beginning immediately with the Peptide T infusions secondly, a clearance pattern preceded by deterioration. No serious side effects were noted.
