Ideology, Nationalism, and Architecture: Representations of Kurdish Sites in Turkish Art Historiography
Authors: Açikyildiz Birgül
Published: May 2022

This article discusses how the narrative of Turkish national historiography, crafted by Turkish elites in the 1930s in light of the official doctrine of the Turkish History Thesis and the Sun Language Thesis, attempted to Turkify the patronage of historical buildings constructed by diverse ethnic and religious communities of the country’s eastern region. I focus on the architectural production of the seven Kurdish dynasties that ruled a large area in the Middle East from the tenth to the mid-nineteenth century. Kurdish rulers constructed a large number of urban monuments bearing their names. These sites were appropriated into the Turkish national historiography in a denial of their Kurdish origins. This approach to history has rendered Kurdish material culture all but invisible, pushing the understanding of Kurdish architectural patronage and identity to the academic margins. This study aims to develop an alternative approach to the history of urban and architectural production in eastern and south-eastern Turkey, and opens a discussion for a definition of Kurdish art and architecture.
Ex Africa Aliquid Novum [There is something new coming from Africa]: Herman Haan and Aldo van Eyck’s Journeys in a Pseudo-Ethnographic Vein
Authors: Velasco Perez Alvaro
Published: May 2022

To the field of professional architecture in Europe in the aftermath of World War II, the deserts of Western Africa were a margin that was viewed as an exterior to the modern metropolis and as a realm of escapism. However, to the ethnographic practices that had developed since the late 1800s, the notion of a desert hinterland supposed a primordial land, reflected in forms of habitation. For architects Herman Haan (1914–96) and Aldo van Eyck (1918–99), the desert was a tense geography that moved between being outside and at home. Revisiting the diaries from Haan and van Eyck’s journeys and their mediation of ethnographic methodologies alongside their engagement with modernist design, this article proposes that Haan’s impressions connect two seemingly opposite contexts: the Dogon lands on the Niger River, and Rotterdam. I argue that, in the architectural and ethnographic amateurism of Haan, the modernist metropolis and its exteriors were not delimited, distinct realms, but were rather engaged in a fluctuating relationship reflective of the contemporary fascination with post-Eurocentric landscapes in the discipline of architecture. I assert that this process of immersion was in fact a process of internalization of spatial experience.
Ibb’s Grand Mosque: Heritage at Risk in Yemen’s Hinterland
Authors: Saleh Al-Haj Mohamed , Filson Lily
Published: May 2022

The Grand Mosque of Ibb, Yemen, also called the ʻUmar Caliph Mosque, is a critically endangered structure that has been a seat of the Shafiʽi school of Islamic jurisprudence since the twelfth century. From the sixteenth century through the present, this identity became marginalized due to the changing political conditions of Lower Yemen. The present state of the mosque testifies to multiple phases of neglect, and the destruction of a complex that served as both a house of worship and a university; collapses and modern interventions have obscured much of its earlier grandeur. This study analyses the Grand Mosque’s destruction and deterioration through its distinct historic periods. For the Grand Mosque’s most recent history, photographs and interviews conducted by geographer Mohamed Saleh Al-Haj, a local resident of Ibb, are presented in collaboration with art historian Lily Filson, a colleague in the United States. The necessity of this international scholarly teamwork underscores the difficulties and challenges of conservation and fieldwork in Ibb. The Grand Mosque faces imminent risk because of its central location within Yemen, a hinterland within Islamic architectural scholarship and the site of a civil war that has claimed irreplaceable monuments and a staggering human toll since 2014.

Extra-illustrating Rousseau’s Julie, ou La Nouvelle Héloïse: The case of the Defer de Maisonneuve edition (1793–1800)
Authors: Lewis Ann
Published: May 2022

While scholarly treatments of extra-illustration have focused almost exclusively on the Anglo-American context, this article considers the phenomenon from a French perspective, by examining two contrasting but previously unstudied extra-illustrated copies of Rousseau’s bestselling novel Julie, ou La Nouvelle Héloïse (1761), each hosted within the large-scale Defer de Maisonneuve edition of Rousseau’s Œuvres (1793–1800). The present article compares these spectacular copies and situates them in the context of French traditions of bibliophilia and connoisseurship, thus nuancing the picture of extra-illustration, which has emerged from Anglo-American accounts, and adding a new dimension to the growing field of work on the iconography surrounding Julie. The two copies, held by the British Library (London, United Kingdom) and Bayerische Staatsbibliothek (Munich, Germany), contain multiple artists’ series of illustrations and individual prints depicting scenes from Julie originally intended for other editions. Each thus provides an intricate choreography of visual readings and configures new connections and possibilities for the reader/viewer, while breaking up the traditional relationship between text and image typically found in eighteenth-century illustrated editions. In their very different scale and presentation of prints (number, size, type, arrangement and binding), they suggest highly divergent practices of collecting, displaying and viewing/reading, inclining variously more to the arts of the book and literary culture in one case, or towards print connoisseurship in the other.

Published: May 2022

INTRODUCTION:

Cannabidiol (CBD), a CBR2 agonist with limited psychic effects, antagonizes CB1/CB2 receptors. Allelic variation CNR1 (gene for CBR1) rs806378 and FAAH rs324420 were associated with altered gut motility and sensation. This study aimed to compare the pharmacodynamics and clinical effects of a 4-week treatment with pharmaceutical-grade CBD vs placebo and assess the interactions of FAAH and CNR1 gene variants on the effects of CBD in patients with functional dyspepsia (FD).

METHODS:

We performed a randomized, double-blinded, placebo-controlled (1:1 ratio) study of CBD b.i.d. (20 mg/kg/d according to the US Food and Drug Administration escalation guidance) in FD patients with nondelayed gastric emptying (GE) at baseline. Symptoms were assessed by validated daily symptom diary (0–4 scale for upper abdominal pain, nausea, and bloating), weekly assessment of adequate relief, Leuven Postprandial Distress Scale (8 symptoms, adjectival scores rated 0–4 for severity), and quality of life (Short-Form Nepean Dyspepsia Index [average of 10 dimensions each on a 5-point scale]). After the 4-week treatment, all patients underwent measurements of GE of solids, gastric volumes, and Ensure nutrient satiation test. Statistical analysis compared 2 treatments for all endpoints and the effects of CBD in association with FAAH rs324420 and CNR1 rs806378.

RESULTS:

CBD and placebo effects on physiological functions and patient response outcomes were not significantly different. There were borderline CBD treatment-by-genotype interactions: rs806378 CNR1 with Leuven Postprandial Distress Scale (P = 0.06) and GE solids (P = 0.12).

DISCUSSION:

Approved doses of CBD used off-label do not relieve FD with normal baseline GE of solids or alter gastric motor functions and satiation. CBD treatment-by-gene interactions suggest potential benefits for postprandial distress with CNR1 rs806378 T allele.

Effects of Additional Polyvinyl Alcohol (PVA) on the Physiochemical Properties of Chitosan-Glutaraldehyde-Gelatine Bioplastic
Authors: Jufri Muh , Lusiana Retno Ariadi , Prasetya Nor Basid Adiwibawa
Published: May 2022

This study investigated the effects of additional PVA on the physicochemical properties of the chitosan-glutaraldehyde/gelatin bioplastic composite. The best results of the bioplastic film were obtained at a concentration of 3% PVA, with a tensile strength value of 3.3 MPa, flexibility reached 54%, a thickness value of 0.24 mm, percentage of inhibition against E. coli and S. aureus was 21.8% and 8.8% respectively. The FTIR spectrum results showed no change in the wavenumber of the chitosan and gelatin chitosan spectrum with OH, CO, and NH functional groups. The spectrum indicates that only physical interactions occurred. The bioplastics are similar in thermal stability and have slight differences in bioplastic morphological contours. The average thickness of the bioplastics is between 0.20–0.26 mm. Based on the Japanese Industrial Standard (JIS), all bioplastics meet the standard thickness, which is < 0.25 mm, excluding chitosan, which has a thickness of 0.26 mm. The addition of PVA into the bioplastics structure increased the hydrophobicity, pH resistance, and flexibility of bioplastics. Meanwhile, additional PVA decreased biodegradability, only degraded by 60% at eight weeks. Based on these data, not all bioplastics can meet the degradation time criteria set by the international bioplastic standard ASTM D-6002, that bioplastics must be 100% degraded within eight weeks. Bioplastics made from chitosan and chitosan-gelatin have been degraded by 90% for 48 weeks. Based on the antibacterial properties, the inclusion of PVA into the bioplastic structure enhances the antibacterial properties.

Published: May 2022

In present times the HAP is of great interest among researchers because of its similar characteristics similar to
human bone. The HAP can be synthesized in two ways, through chemical methods and through extraction from
natural resources. The chemical route can be expensive and un-sustained for the environment while as the extraction
method from natural resources can be key to make the whole process environmentally friendly. Even though HAP is
similar to human bone it lacks the necessary mechanical properties which are essential for bio-implants. It is a wellknown fact that Stainless Steel (316L) is suitably bio-compatible, but it also lacks the necessary Anti-bacterial
properties which can be improved by addition of an alternative candidate having anti-bacterial properties such as
Silver (Ag). This study proposes development of a hybrid composite of (SS316L, HAP, Ag) through powder metallurgy
route with improved properties.

Rice Husk Ash as a Partial Replacement of Cement in High Strength Concrete containing Fly Ash
Authors: Ahmed Shiren Osman
Published: May 2022

Rice husk ash (RHA) is an agricultural waste product which is a pozzolanic material. It is blended with the cement for
manufacturing concrete. It reduces the environmental impact of the cement industry. Blending of cement with
supplementary cementitious materials like fly ash and rice husk ash makes concrete more durable. This paper studies
effect of a partial replacement of cement with various ratios of rice husk ash (RHA) on physical and mechanical
properties of concrete. Three mixtures were prepared with proportions of 4, 8, and 16% RHA by weight of cement in
addition to 15% fly ash (FA) by weight of cement to be compared with a reference mixture with 100% Portland
cement. Compressive strength test, tensile strength test, flexural strength test and rate of water absorption test were
performed at different ages of curing. Test results have reflected that the compressive strength, tensile strength and
flexural strength achieved with 16% replacement of cement with RHA maximum increase. Compressive strength
increased with 16% RHA by 12.5% at 56 days age compared to compressive strength of control mix. Flexural strength
increased with 16% RHA by 17.33% at 56 days age compared to flexural strength of control mix. There is significant
development in mechanical properties compared to control mix. The mixture with 16% RHA showed the lowest ratios
of water absorption by about 2.8% and 2% at 28 and 56 days of cuing, respectively.
Study the behaviour of cement mortar containing jute fiber along with partial replacement of cement with eggshell powder
Authors: Saini Aditya Kumar , Singh Abhinav , Tiwari Abhishek
Published: May 2022

The construction industry's key materials are mortar and concrete. Cement is a key component in the production of
mortar and concrete. Natural limestone is used to make cement. When limestone is burned to make cement, carbon
dioxide gas is liberated as a by-product, which is considered as a greenhouse gas with adverse environmental effects.
Waste materials can be used in the manufacture of mortar and concrete to minimize negative consequences and
natural resource utilization. In investigations, a powdered form of eggshell passed through a 90µm IS sieve and jute
fiber was employed as a partial alternative for cement in the production of cement mortar. Eggshells are abundant in
calcium oxide and have a chemical composition similar to natural limestone. The cement mortar is formed with a 1:3
mix ratio. ESP is added in percentages of 0%, 3%, 6%, 9%, and 12% by cement weight. Mechanical properties such as
split-tensile, compressive and flexural strength with percent Jute fiber were compared to a nominal cement mortar
cube. The ideal fiber length is 5-10mm. According to the findings, increasing the percentage of eggshell powder (ESP)
in the mortar mix along with jute fiber (JF) increases the split-tensile, compressive and flexural strength of the cement
mortar specimen. The effects of ESP and jute fiber on split-tensile, flexural and compressive strength, weight, water
absorption, bulk density, and sorptivity has been evaluated.

Published: May 2022

Markov chains epitomize a class of stochastic process for a wide range of applications. Specifically, discrete time Markov chains (DTMC) is employed to model the transition probabilities between discrete states with the help of the matrices. To examine and forecast the time series the Markov chain model is applied. The most important indicator in macroeconomics is inflation, which persisted in double digits in 1970s and also in last several years. Different states are checked with the model by using inflation rate data form July 2000 to April 2015. A simulation technique used for random sequences of inflation predefine states for one year and take 1st quarter data from it and then model the estimates by maximum likelihood and maximum likelihood with Laplace smoothing methods and check the equilibrium distribution using both techniques. Estimates obtained by Laplace Smoothing technique are reliable because it controls the variation on the Maximum Likelihood estimates.

Published: May 2022

Distributed programming paradigms such as MapReduce and Spark have alleviated sequential bottleneck while mining of massive transaction databases. Of significant importance is mining High Utility Itemset (HUI) that incorporates the revenue of the items purchased in a transaction. Although a few algorithms to mine HUIs in the distributed environment exist, workload skew and data transfer overhead due to shuffling operations remain major issues. In the current study, Parallel Utility Computation (PUC) algorithm has been proposed with novel grouping and load balancing strategies for an efficient mining of HUIs in a distributed environment. To group the items, Transaction Weighted Utility (TWU) values as a degree of transaction similarity is employed. Subsequently, these groups are assigned to the nodes across the cluster by taking into account the mining load due to the items in the group. Experimental evaluation on real and synthetic datasets demonstrate that PUC with TWU grouping in conjunction with load balancing converges mining faster. Due to reduced data transfer, and load balancing-based assignment strategy, PUC outperforms different grouping strategies and random assignment of groups across the cluster. Also, PUC is shown to be faster than PHUI-Growth algorithm with a promising speedup.

The reactor pressure vessel was contact sealed with a double-channel O-ring made of Inconel 718 alloy and nuclear power material SA508. The fretting wear characteristics of Inconel 718 O-tube and SA508 plate friction pair were tested by fretting wear testing machine to explore the failure mechanism of reactor pressure vessel seal system. The test conditions are as follows: normal temperature, normal loads of 10, 20, and 40 N, displacement amplitude of 600 μm, the number of cycles of 10,000, and frequency of 4 Hz. Results show that the coefficient of friction (COF) increased with increasing normal force. Significant material losses were detected during the relative sliding of the contact surface of SA508. A large number of abrasive dust accumulated at the edge of the contact zone, forming a large number of oxides. During the friction of Inconel 718 O-ring, plastic deformation occurred, and a plastic flow layer was formed. The plastic deformation flow at the contact point formed an adhesive connection point, producing adhesive wear and oxidative wear. The wear mechanism was characterized by the combination of oxidative wear and abrasive wear.

Homologous recombination deficiency (HRD) commonly occurs in breast cancer, which is the second cause of cancer death in women with a high rate of relapse and poor outcomes. Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer. Thus, we aim to develop a prognostic signature based on HRD expecting to help improve outcomes in TNBC. The Cancer Genome Atlas (TCGA)–TNBC cohort was divided into the training set and the testing set randomly. Sixteen genes were filtered from the prognostic HRD-associated genes to establish a prognostic model in the training set. Patients were divided into high-risk and low-risk groups based on the median value of the risk score. Prognosis analysis showed that the high-risk group was associated with a worse prognosis in the training set, the testing set, the entire TCGA–TNBC cohort, and the METABRIC–TNBC cohort. The time-dependent receiver operating characteristic curve showed that our model had very good accuracy in the prediction of 1–5-year overall survival in the TCGA–TNBC cohort. Besides, a comparison of the area under curve value and C-index between our model and four published models showed that our model had the best predictive efficiency compared to other models. Subsequently, a nomogram was established. Finally, our finding also indicated that our model was associated with immunoregulation in TNBC and had the potential to be the target for TNBC treatment. Therefore, our findings not only provided a new strategy in the personalized prognosis management of TNBC but also offered new insight into precision treatment in TNBC.
Rethinking Dionysus and Apollo: Redrawing Today’s Philosophical Chessboard
Authors: Segovia Carlos A.
Published: May 2022

This essay pursues Gilbert Durand’s plea for a new anthropological spirit that would overcome the bureaucracy-or-madness dichotomy which has since Nietzsche left its imprint upon contemporary thought, forcing it to choose between an “Apollonian” ontology established upon some kind of first principle and a “Dionysian” ontology consisting in the erasure of any founding norm. It does so by reclaiming Dionysus and Apollo’s original twin-ness and dual affirmation in dialogue with contemporary anthropological theory, especially Roy Wagner’s thesis on the interplay of “elicitation” and “containment” in sociocultural life. What would happen then, I ask, if we were to reimagine today’s philosophical game – which after Heidegger Deleuze, and Derrida turns variously and increasingly around subtraction – otherwise: as a chiastic board on which Apollo would cut Dionysus’s continuum, which Dionysus would in turn restore despite Apollo’s cuts, and on which the obliteration of any of the two gods would entail the inevitable dismemberment of the other? Accordingly, I offer a full reassessment of Dionysus’s and Apollo’s complementary roles in ancient-Greek culture in discussion not only with Nietzsche’s Dionysian philosophy but also with Ihab Hassan’s postmodern critique of Orpheus. All of it less with the purpose of putting forward a new metaphysics than with the intent of restating the translucent-ness that keeps together reality and thought against any claim that they are either transparent or opaque to one another.
A review of the characteristic properties of selected tobacco chemicals and their associated etiological risks

Published: May 2022

Objectives

Despite the quantum of research findings on tobacco epidemic, a review on the formation characteristics of nicotine, aldehydes and phenols, and their associated etiological risks is still limited in literature. Accordingly, knowledge on the chemical properties and free radical formation during tobacco burning is an important subject towards unravelling the relationship between smoking behaviour and disease. This review investigates how scientific efforts have been advanced towards understanding the release of molecular products from the thermal degradation of tobacco, and harm reduction strategies among cigarette smokers in general. The mechanistic characteristics of nicotine and selected aldehydes are critically examined in this review. For the purpose of this work, articles published during the period 2004–2021 and archived in PubMed, Google Scholar, Medley, Cochrane, and Web of Science were used. The articles were selected based on the health impacts of cigarette smoking, tobacco burning kinetics, tobacco cessation and tobacco as a precursor for emerging diseases such as Covid-19.

Content

The toxicity of cigarette smoke is directly correlated with its chemical composition derived from the pyrolysis of tobacco stem and leaves. Most of the harmful toxic substances are generated by pyrolysis during smoking and depends on pyrolysis conditions. Detailed studies have been conducted on the kinetics of nicotine by use of robust theoretical models in order to determine the rate constants of reactions in nicotine and those of nicotine dissociation via C–C and C–N scission, yielding pyridinyl and methyl radicals, respectively. Research has suggested that acetaldehyde enhances the effect of nicotine, which in turn reinforces addiction characteristics whereas acrolein and crotonaldehyde are ciliatoxic, and can inhibit lung clearance. On the other hand, phenol affects liver enzymes, lungs, kidneys, and the cardiovascular system while m-cresol attacks the nervous system.

Summary and Outlook

The characteristics of chemical release during tobacco burning are very important in the tobacco industry and the cigarette smoking community. Understanding individual chemical formation from cigarette smoking will provide the necessary information needed to formulate sound tobacco reform policies from a chemical standpoint. Nonetheless, intense research is needed in this field in order to prescribe possible measures to deter cigarette smoking addiction and ameliorate the grave miseries bedevilling the tobacco smoking community.

Published: May 2022

To synthesize the scientific evidence on physical exercise protocols for the oldest-old we searched PubMed, Scopus, Web of Science, CINAHL, Medline, and gray literature up to January 2021. Eligibility criteria included investigation of the oldest-old population (≥80 years); use of intervention protocols with appropriate and effective variables for a physical exercise program (type, intensity, frequency, and duration); reporting positive effects of the interventions on physical fitness, execution of activities of daily living, and quality of life of the oldest-old; an experimental and/or quasiexperimental (randomized or nonrandomized) study design. Twenty studies were included. Physical exercise protocols for the oldest-old should include strength, power, aerobic endurance, flexibility, balance, and joint mobility exercises. These exercises are effective in attenuating or minimizing the declines that occur during aging, improving factors such as gait, fall rate, and functional capacity.
