Wie wirtschaftlich sind private Investitionen in öffentlich geförderten Mietwohnungsbau?
Authors: Lerbs Oliver , Nobbe Lena 
Published: June 2021

ZusammenfassungIn vielen deutschen Städten herrscht akuter Mangel an preisgünstigem Wohnraum. Die Politik hat sich vor diesem Hintergrund zum Ziel gesetzt, die Anzahl der Sozialwohnungen zu erhöhen. Aufgrund begrenzter öffentlicher Mittel muss zur Erreichung dieses Zieles privates Kapital mobilisiert werden. Dies bedeutet Investitionen privat-gewerblicher Wohnungsunternehmen in öffentlich geförderten Wohnraum. Entsprechende Investitionen werden durch Förderprogramme der Bundesländer subventioniert, gelten jedoch in Branchenkreisen trotz vorhandener Förderung als wenig wirtschaftlich. Anhand realitätsnaher Modellrechnungen zeigt dieser Beitrag, dass die derzeit zu erwartende Wirtschaftlichkeit privater Investitionen in öffentlich geförderten Wohnraum tatsächlich gering ist. Dies gilt selbst unter Berücksichtigung der jüngsten Verbesserungen im Wohnraumförderungsrecht, der im Jahr 2019 eingeführten Sonderabschreibung im Mietwohnungsbau sowie den aktuell historisch günstigen Fremdfinanzierungsbedingungen für Wohnungsunternehmen. Weiter zeigt der Beitrag, dass Kommunen in der preisvergünstigten Veräußerung städtischer Grundstücke an bauwillige Investoren über ein wohnungspolitisches Instrument verfügen, mit dem die Wirtschaftlichkeit privater Investitionen in öffentlich geförderten Wohnraum potenziell entscheidend gesteigert werden kann.
Un nuevo pavimento romano de la Baetica: el llamado Mosaico de los Delfines de Naeva (Cantillana, Sevilla)
Authors: Vargas-Vázquez Sebastián , López Monteagudo Guadalupe , Valiente de Santis José Antonio 
Published: June 2021

Se analiza un mosaico recientemente descubierto en la antigua ciudad de Naeva, cuya cronología podría inscribirse en el s. III d. C. por sus características estilísticas y por los datos derivados del estudio de materiales que evidencian el abandono del edificio en el que se enmarca este pavimento musivo a finales de dicha centuria. El trabajo profundiza, además, en la principal particularidad del mosaico, que estriba en su aspecto formal, al cubrir toda la superficie del impluvium y del brocal de un pozo, de un atrium columnado posiblemente perteneciente a una importante domus urbana. La temática representada en el mosaico, dotado de rica policromía, compagina los elementos de agua y tierra mediante la representación, localizada en el suelo, de una abundante fauna íctica y de una singular escena de sátiros y ménades enmarcados en un ambiente de espesas vides, desarrollada en torno al brocal del pozo. A todo ello habría que sumar el carácter efectista del conjunto, provocado por el agua y la posible inundación del centro del atrio, preparado para contener en momentos determinados una lámina de agua que concedería mayor realismo a la escena marina.

Abstract
Since its emergence in late 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been spreading remarkably fast worldwide. Effective countermeasures require the rapid development of data and tools to monitor its spread and better understand immunogenic profile. However, limited information is available about the tools and target of the immune responses to SARS-CoV-2. In this study, we excogitated a new approach for analyzing phylogenetic relationships by using the whole prototype proteome sequences. Phylogenetic analysis on the whole prototype proteome sequences showed that SARS-CoV-2 was a direct descendant of Bat-CoV and was closely related to Pangolin-CoV, Bat-SL-CoV, and SARS-CoV. The pairwise comparison of SARS-CoV-2 with Bat-CoV showed an unusual replacement of the motif consisting of seven amino acids (NNLDSKV) within the spike protein of SARS-CoV-2. The replaced motif in the spike protein of SARS-CoV-2 was found in 12 other species, including a conserved surface protein of a malaria-causing pathogen, Plasmodium malariae. We further identified the T and B cell epitope sequence homology of SARS-CoV-2 spike protein with conserved surface protein of P. malariae using the Immune Epitope Database and Analysis Resource (IEDB). The shared immunodominant epitopes may provide immunity against SARS-CoV-2 infection to those previously infected with P. malariae.

Published: June 2021

Abstract

Objectives
Obesity is a growing problem in type 1 diabetes mellitus (T1DM) today. The aim of our study is to determine the frequency of overweight/obesity at the time of diagnosis and during follow-up in children with T1DM as well as review the conditions that may accompany.

Methods
A total of 315 patients with T1DM were retrospectively analyzed. The patients were divided into two groups as normal weight and overweight/obese. The two groups were compared in terms of age at diagnosis, birth weight, anthropometric measurements, insulin dose used and blood pressure measurements, and insulin, c-peptide, hemoglobin A1c, triglyceride, and high-density lipoprotein levels at the time of diagnosis and follow-up.

Results
The height, weight and body mass index standard deviation (BMI SD) scores, and c-peptide levels at the time of diagnosis of the overweight/obese group were higher than those with normal weight (p<0.001 and p = 0.008, respectively). The frequency of dyslipidemia and hypertension was higher in the overweight/obese group than in the normal weight group [18.2 vs. 5% (p = 0.015) and 10 vs. 1.5% (p = 0.003), respectively].

Conclusions
In our study, the fact that the overweight/obese group had higher BMI and c-peptide and lower HDL values at the time of diagnosis can be evaluated as indicators that insulin resistance syndrome can accompany T1DM from the beginning (double diabetes). When determining the treatment and follow-up strategies of patients with T1DM, considering the risk of obesity and taking the necessary precautions is very important in terms of morbidity.

Vowel development in young Mandarin-English bilingual children
Authors: Yang Jing 
Published: June 2021

Abstract
This study examined the development of vowel categories in young Mandarin -English bilingual children. The participants included 35 children aged between 3 and 4 years old (15 Mandarin-English bilinguals, six English monolinguals, and 14 Mandarin monolinguals). The bilingual children were divided into two groups: one group had a shorter duration (<1 year) of intensive immersion in English (Bi-low group) and one group had a longer duration (>1 year) of intensive immersion in English (Bi-high group). The participants were recorded producing one list of Mandarin words containing the vowels /a, i, u, y, ɤ/ and/or one list of English words containing the vowels /i, ɪ, e, ɛ, æ, u, ʊ, o, ɑ, ʌ/. Formant frequency values were extracted at five equidistant time locations (the 20–35–50–65–80% point) over the course of vowel duration. Cross-language and within-language comparisons were conducted on the midpoint formant values and formant trajectories. The results showed that children in the Bi-low group produced their English vowels into clusters and showed positional deviations from the monolingual targets. However, they maintained the phonetic features of their native vowel sounds well and mainly used an assimilatory process to organize the vowel systems. Children in the Bi-high group separated their English vowels well. They used both assimilatory and dissimilatory processes to construct and refine the two vowel systems. These bilingual children approximated monolingual English children to a better extent than the children in the Bi-low group. However, when compared to the monolingual peers, they demonstrated observable deviations in both L1 and L2.

Abstract
Solar energy is a clean and abundant energy source. In a photoelectrochemical cell, energy from sunlight is captured and converted into electric power, chemical fuels such as hydrogen is employed to degrade organic pollutants. ZnO is a promising material for photoelectrocatalysis due to its remarkable properties. The aim of this review is to perform an exhaustive revision of nanostructured ZnO synthesis by electrochemical anodization in order to control surface characteristics of this material through anodization parameters such as electrolyte type and concentration, potential, time, temperature, stirring, and post treatment. Finally, application of ZnO nanostructures is overviewed to observe how surface characteristics affected the ZnO photoelectrocatalytic performance.

Published: June 2021

AbstractThe following article describes the development of a millimetre wave based real-time imaging system for three dimensional non-destructive testing of goods. For this purpose a rotating antenna is used which is fed from an FMCW radar. The received measuring data is processed with a SAR algorithm. Due to the fact that a reflexive measurement method is used, the integration of the system into existing systems is simplified. To make the computing power-intensive SAR image processing possible, the complete signal processing chain of the image processing is executed on the graphics card. The article elucidates the concept for calculating the measurement parameters which have to be elaborated for the implementation of the image processing of the whole system.

Les transformations fonctionnelles de la cour et la culture du livre dans la Hongrie royale et en Transylvanie aux XVIe ET XVIIe siècles
Authors: Monok István 
Published: June 2021

AbstractLa cour royale de Mathias Corvin (1443–1490 ; 1458–1490) et celle des rois Jagellons jouent jusqu’au XVesiècle, dans la vie intellectuelle du royaume de Hongrie, un rôle comparable à celui des cours royales en Europe occidentale. Mais l’occupation de la capitale (Buda) par les Turcs (1541) et l’absence de souverain « national » transforment profondément le rôle des familles aristocratiques pour ce qui concerne tant l’organisation de la vie culturelle que la vie de l’Église. Parallèlement, la Réforme protestante progresse au XVIesiècle en Hongrie et en Transylvanie, cette dernière devenue une principauté pratiquement indépendante. Les nouveaux acteurs autour desquels se développe dès lors la vie culturelle dans le pays sont les grands aristocrates et les cours qu’ils réunissent à leur entour : les Bánffy, Batthyány, Nádasdy, Perényi, Rákóczi, Esterházy et quelques autres. En Transylvanie, le rôle de la cour princière reste dominant, grâce à sa richesse relative par rapport aux cours seigneuriales. Si l’aristocratie de Hongrie et de Transylvanie se convertit très majoritairement à la Réforme au XVIesiècle, la politique des Habsbourg et les progrès de la Contre-Réforme entraînent un vaste mouvement de reconversion, mais en Hongrie seulement, au XVIIesiècle. À la fin du siècle, ces territoires sont pleinement réintégrés dans les territoires des Habsbourg : dès lors, la question de la modernité se déploie de plus en plus nettement, à laquelle se joint la nouvelle problématique de l’identité collective, puis nationale.
Structural behaviour of CFRP reinforced concrete members under monotonic and cyclic long-term loading
Authors: El Ghadioui Redouan , Hiesch Dominik , Bujotzek Lukas , Proske Tilo , Graubner Carl-Alexander 
Published: June 2021

AbstractA large percentage of the damages to reinforced concrete structures is caused by corrosion of the reinforcement steel, which often leads to expensive repairs or new construction of existing structures. Due to their high strength and resistance to corrosion, reinforcements made of carbon fibre-reinforced polymers (CFRP) are becoming more and more important in structural engineering. It is expected, that the service life of CFRP reinforced concrete (RC) members can be significantly increased as the strength-reduction due to corrosion is negligible compared to conventional RC members. Therefore, precise knowledge of the long-term behaviour of CFRP RC members is required in order to ensure safe and economic design. This paper presents experimental investigations on the long-term behaviour of CFRP RC members as well as steel-reinforced RC members under monotonic and cyclic long-term loading with varying load levels, different cross-sectional shapes and shear slendernesses. Accompanying experiments on the concrete creep behaviour that were conducted within the investigations are shown. Within the scope of the experiments, the deflections as well as the strains on the top and bottom side of the RC members were measured using displacement sensors and strain gauges. The experimental data is evaluated, especially with regard to the time-dependent deflections. The data is compared to existing mechanical and empirical models, which are usually derived for steel-reinforced RC members. Based on the experimental data, the time-dependent reduction of stiffness and conclusions for the calculation of deflections are shown.

Authors: Mahmood Trifa , Mohammed Mohammed , Gharib Dana , Mohamad Taha , Mohammed Muhsin , Rahim Araz 
Published: June 2021

Background
The difficulty in differentiating functional gastrointestinal disorders and inflammatory bowel diseases in patients presenting with abdominal symptoms direct us to the use of fecal inflammatory biomarkers that are specific to intestinal inflammation.
Objectives
To assess the benefits of fecal calprotectin (FC) in patients presenting with lower abdominal symptoms. Also, correlating the FC and CRP titer with abdominal pain severity.
Patients and Methods
Prospective cross-sectional study in Kurdistan Center for Gastroenterology and Hepatology (KCGH), Sulaimaniyah city, Northern Iraq. A total of 174 patients with IBS according to Rome IV criteria, who visited KCGH, met the inclusion criteria. FC titer measured before colonoscopy appointment, abdominal pain severity scored according to visual scale, and colonoscopy performed by a specialized gastroenterologist.
Results
The FC level was below 50ug/g for 91.3% of patients with normal endoscopy; all of the IBD cases had FC level above 100ug/g. Seven of the eight patients with non-inflamed polyp or diverticuli had an FC level of less than 50ug/g. Moreover, in this study, the CRP level is also significantly higher among IBD cases than in patients with normal colonoscopy.
Conclusion
FC titer is a useful measure before the decision for colonoscopy especially in cases not having alarm symptoms and other comorbidities. FC and CRP level is associated with the severity of abdominal pain.
USING CYSTATIN C TO ASSESS KIDNEY DAMAGE IN BETA THALASSEMIC PATIENTS RESIDING IN SULAIMANI CITY
Authors: Najat Dereen , Karim Lana 
Published: June 2021

Background
In beta-thalassemia, major patients usually have anemia and iron overload which affects the function of many organs such as the heart, liver, and kidneys. Many previous studies concentrated on heart and liver complications, but fewer researches have focused on kidney dysfunction.
Objectives
Our main aim was to study renal dysfunction in BTM patients in the Sulaimani thalassemia center, using both novel urinary dysfunction markers (cystatin C) and traditional urine biomarkers.
Methods
This study was a case-control study (101 thalassemic patients and 97 controls). We studied the hematological parameters of the patients; we also assessed kidney function using cystatin c, serum creatinine, and blood urea and albumin creatinine ratio. T-test was used to assess the difference between study and control groups.
Results
Our results for the thalassemic group were as follow; serum iron levels were 240.27 (std.= ±80.80) µg/dl, mean serum ferritin was 1559.32 (std= ±1066.02) ng/ml; mean haemoglobin levels were 7.99 (std=± 1.14). The mean blood urea was 26.13 mg/dl (std.= ±7.38), serum creatinine was 0.43 mg/dl (std.=±0.16). The mean urinary albumin creatinine ratio was 271.14 mg/g (std=±131.23); mean eGFR (creatinine) was 170.0 (std.=101.1); mean eGFR (cystatin c) was 76.7 ml/min/1.73 (std.=±39.5).
Conclusion
Our results showed the majority of BTM were anaemic and suffered from iron overload despite the use of iron chelating agents. Our kidney function tests showed that although traditional urinary markers doesn’t show kidney damage, the novel biomarker cystatin C showed BTM might have early kidney damage.

Authors: Mustafa Sabir , Hassan Zhwan 
Published: June 2021

Background
One of the most common deformities after the occurrence of hand burn is web space contracture which has both aesthetic and functional drawbacks. In this prospective study combined rhomboid and double Z-plasty technique is used to reconstruct web space contracture.
Objectives
Is to assess a combination of the rhomboid flap with a double Z-plasty technique for reconstruction of palmar and dorsal web space contractures to decrease shortcoming and achieve better functional and aesthetic results.
Patients and methods
18 webs of 9 patients with postburn web space contracture of palmar and dorsal type were submitted to reconstruction using combined rhomboid and double Z-plasty technique.
Results
The average age of the 9 patients included in our study was 24 years and most of them developed web space contracture as a result of a flame burn. The duration of their contracture ranged between (2-20) years. Our patients were satisfied with the results both regarding the functional and aesthetic appearance of the webspace. After using this technique for reconstruction of 18 webs which were included in our study, we didn’t notice any significant complications in terms of flap necrosis, digital ischemia, wound dehiscence or infection, and recurrence of contracture.
Conclusion
The combined rhomboid flap and double Z-plasty technique is a simple and effective method for reconstruction of postburn web space contracture of the hands.
