Published: March 2021

Abstract: Because of chronic and progressive nature of disease
congestive heart failure become standart therapies. Peritoneal dialysis
(PD) has been reported as a long-term maintenance treatment of refracter
congestive heart failure (RCHF).In this study, we aimed to evaluate the
outcome of patients with RCHF, treated with PD in our center. Patients
and methods: Twenty-four incident PD patients with RCHF and chronic
kidney disease stage IV. The CAPD programme consisted of 2–3 exchanges
daily and one exchange nightly. In follow-up period clinical and
echocardiographic biochemical findings and requirement of
hospitalization were recorded. Results: Fifteen patients (66.7%) were
male and mean age was 62,75 years. The etiology of congestive heart
failure were hypertensive cardiomyopathy (5), ischemic coronary artery
disease (12), diabetes mellitus (6), dilated cardiomyopathy (1). Under
the PD treatment the average daily urine volume and ultrafiltration of
the patients were 800-1000 ml and 1000-15000 ml respectively. Ten
patients were followed for 24 months, eight patients were followed for
12 months. During the follow up period, there were regression in class
of heart failure of NYHA (class IV to class II in 18 patients) ,
decrease in the body weights and an increase of serum sodium levels in
all patients. Only 2 patients were hospitalised for cardiovascular
disase in 2 years. During the follow-up period, 1 patient was
transferred to hemodialysis due to peritonitis. In conclusion; in
patients with resistant congestive heart failure and non-dialysis
chronic renal failure PD in addition to standard treatment, may be safe
treatment choice.

Authors: Keiler James , Scott Erik , George Timothy , Ailawadi Gorav
Published: March 2021

Pseudoaneurysm of the ascending aorta is a rare complication of cardiac
surgery occurring in less than 0.5% of cases. Deep sternal wound
infections (DSWI) increase the likelihood of aortic pseudoaneurysm. An
ascending aortic pseudoaneurysm has high morbidity and the mortality
rate has ranged from 29%-46% in the medical literature. We report a
complex patient who underwent an AVR at an outside hospital complicated
by DSWI requiring pectoral flap coverage. Months later, he was
transferred to our institution with acute swelling of his sternum,
diagnosed as massive aortic pseudoaneurysm originating from the
cannulation site.

Is it reasonable to use existing outside soil spray seeding technology to prepare artificial soil under slope aspect and landslide in alpine area？
Authors: Jiang Xue , Ai Hao , Zhu Ke , Huang Bocong , Ai Xiaoyan , Ai Ying-wei
Published: March 2021

Knowledge about artificial soil nutrient of cut-slopes associated with
slope aspect and landslide attributes is vital for understanding
cut-slopes environmental ecosystem and establishing sustainable
artificial soil management practices. Our study focuses on cut-slopes
recovered by slope protect technology in alpine region, where slope
aspect (east-, south-, west-, and north-facing slope) and landslide
(non- and landslide) are dominant environment factors. Integrated
matter-element model and path analysis were adopted to investigate the
effects of slope aspect and landslide on the selected soil properties:
pH, soil organic matter (SOM), alkali-hydrolysable nitrogen (AN), total
phosphorus (TP), available phosphorus (AP), and available potassium
(AK). Both slope aspect and landslide had no significant effect on
artificial soil pH (p > 0.05). Statistically significant
differences were found for artificial SOM, AN, TP, AP, and AK between
the slope aspect and landslide (p < 0.05). SOM, nitrogen (N),
and potassium (K) were limiting factors for artificial soil nutrients on
all slope aspect under landslide. N was a limiting factor for artificial
soil nutrients on all slope aspect under non-landslide. K was a limiting
factor for artificial soil nutrients on all slope aspect under
non-landslide, except for non-landslide-north-facing slope, while SOM
was a limiting factor for artificial soil nutrients on
non-landslide-north-facing slope. Landslide and slope aspect had a
highly significant positive correlation with AN and AK, but negative
correlation with AP. Therefore, it is necessary to formulate different
artificial soil management measures for different slope aspect and
landslide to achieve the most effective slope ecological restoration.

Published: March 2021

Objective This study sought to determine the contractile reserve (CR)
response to exercise stress echocardiography (ESE) quantified by the
novel parameter, non-invasive myocardial work (MW), in subjects with
angiographically proven coronary artery disease (CAD). Methods CR was
measured by the relative change in ejection fraction (EF), global
longitudinal strain (GLS) and MW indices from rest to peak exercise in
304 patients referred for clinically indicated ESE. Positive ESE
patients proceeded to coronary angiography and further risk stratified
based on either percutaneous or surgical intervention. Results
CR and global work index (CR)
significantly decreased with exercise induced ischaemia and
angiographically proven significant CAD (CR
-1.6±3.5%; CR -8.6±511mmHg% decrement,
p<0.001) compared to non-ischaemic patients
(CR 1.4±2.2%; CR 398±404mmHg%
improvement). Global constructive work (CR) was
significantly higher (p<0.0001) in non-ischaemic
(818±457mmHg%) and blunted in ischaemic patients (208±550mmHg%).
CR (AUC 0.81; 95%CI 0.74-0.88) was superior to
CR (AUC 0.75; 95%CI:0.67-0.83),
CR (AUC 0.73, 95%CI:0.64-0.82) and
CR (AUC 0.71; 95%CI:0.62-0.81, p<0.001) to
detect inducible ischaemia. Subgroup analysis showed patients requiring
surgical revascularisation demonstrated a significantly lower
CR (-11.5±7.6%, p<0.05) as a result of
reduced CR (281±573mmHg%, p<0.05) and
increased global wasted work (CR, 289±151mmHg%,
p=0.09). Conclusion Multivessel disease requiring surgical
revascularisation have the greatest reduction in CR. MW may potentially
improve detection of ischaemia and further risk stratification during
ESE to maximise the benefits of revascularisation.

Published: March 2021

Objective: The aim of this study was to ascertain the relationship
between Bethesda category and molecular mutation of thyroid nodules in
patients undergoing thyroidectomy. Design: A retrospective cohort of
patients who underwent thyroidectomy following needle biopsy and
molecular profile testing was performed. Setting: Two tertiary care
academic hospitals. Participants: Consecutive patients with a dominant
thyroid nodule who underwent both USFNA and molecular profile testing
followed by thyroidectomy were included in the study. Main Outcome and
Measures: The main outcome was postoperative diagnosis of thyroid cancer
and aggressivity of disease based on histopathological variants, nodal
metastasis or extra-thyroidal extension. Associations between Bethesda
category, molecular mutation and postoperative pathology was assessed
using descriptive analysis and Chi-square testing. Results: 451 patients
were included. 95.9% (93/97) of patients with a BRAFV600E mutation had
a Bethesda category V or VI (P<0.001), and all had confirmed
thyroid cancer on postoperative pathology. Those with H, K or N RAS or
EIF1AX mutations, gene expression profiling (GEP) or copy number
alterations showed an association with Bethesda categories III and IV
(P≤0.01). Those with no identified molecular mutation had a lower
incidence of aggressive thyroid cancer compared to those with an
identified mutation (12.6% vs 44.3%, P<0.01). Conclusion:
BRAFV600E mutations were associated with thyroid cancer subtypes known
to be more aggressive. These findings may help thyroid specialists
better identify aggressive thyroid nodules associated with indeterminate
Bethesda categories.

Published: March 2021

Objectives: This study investigated the relationship between viral load
and the incidence and recovery of olfactory and gustatory dysfunction
(OD and GD), incidence of respiratory and gastrointestinal symptoms in
COVID-19 patients. Design: A Retrospective Cohort Study. Setting and
Participants: In total 599 outpatients’ cases polymerase chain reaction
(PCR)–confirmed COVID-19-positive patients in Golestan province were
included in the study. Main Outcome Measures: The incidence of OD, GD,
their severity and the time of recovery was determined. The association
of these variables with cycle threshold (CT) values of SARS-CoV-2
polymerase chain reaction was assessed. Results: The mean age of
patients was 38.27 ± 13.62 years. The incidence of general symptoms
included myalgia 70.1%, headache 51.8%, fever 47.7%, and dyspnea
21.4%. 41.9% of patients had gastrointestinal symptoms, including
abdominal pain 26.5%, diarrhea 25.2%, nausea 20.5%, and vomiting
12.9%. 12.2% of patients had comorbidity. The trimester recovery rates
of OD and GD were 93.94% and 94.74%, respectively. The mean recovery
time of OD and GD was 14.56±13.37 and 13.8±3.77 days, respectively. The
mean CT value in all patients was 27.45±4.55. There were significant
associations between CT value with headache (P=0.04), GD (P=0.002) and
OD (P=0.001). Conclusions: The intensity and the recovery of OD and GD
in Covid-19 patients may be affected by initial viral load. Unlike to
respiratory and gastrointestinal symptoms, the OD and GD were associated
with lower viral load. Therefore, it may be recommended to use these
clinical symptoms as an indicator in the initial screening of patients
during pandemics.
CD103 integrin identifies a high IL-10-producing FoxP3+ regulatory T cell population suppressing allergic airway inflammation

Published: March 2021

Background: Although FoxP3+ regulatory T (Treg) cells constitute a
highly heterogeneous population, with different regulatory potential
depending on the context, distinct subsets or phenotypes remain poorly
defined. This hampers the development of immunotherapy for allergic and
autoimmune disorders. This study aimed at characterizing distinct FoxP3+
Treg subpopulations involved in the suppression of Th2-mediated allergic
inflammation in the lung. Methods: We used an established mouse model of
allergic airway disease based on ovalbumin sensitization and challenge
to analyze FoxP3+ Tregs during the induction and resolution of
inflammation, and identify markers that distinguish their most
suppressive phenotypes. We also developed a new knock-in mouse model
(Foxp3creCd103dtr) enabling the specific ablation of CD103+FoxP3+ Tregs
for functional studies. Results: We found that during resolution of
allergic airway inflammation in mice >50% of FoxP3+ Treg
cells expressed the integrin CD103 which marks FoxP3+ Treg cells of high
IL-10 production, increased expression of immunoregulatory molecules
such as KLRG1, ICOS and CD127, and enhanced suppressive capacity for
Th2-mediated inflammatory responses. CD103+FoxP3+ Tregs were essential
for keeping allergic inflammation under control as their specific
depletion in Foxp3creCd103dtr mice lead to severe alveocapillary damage
and eosinophilic pneumonia, markedly reducing the lifespan of the
experimental animals. Conversely, adoptive transfer of CD103+FoxP3+
Tregs effectively treated disease, attenuating Th2 responses and
allergic inflammation in an IL-10-dependent manner. Conclusion: Our
study identifies a novel regulatory T cell population, defined by CD103
expression, programmed to prevent exuberant type 2 inflammation and keep
homeostasis in the respiratory tract under control. This has important
therapeutic implications.

Published: March 2021

Abstract The purpose of this paper is to report a case diagnosed by
bedside echocardiography in which bone cement infiltrated into the
paravertebral vein system after percutaneous vertebroplasty (PVP) and
caused intracardiac cement embolism (ICE). A 79-year-old female patient
had suddenly become unconscious 14 hours after PVP. Emergency bedside
echocardiogram showed that the patient had a strong echo in the right
heart with a small amount of pericardial effusion, suspected of causing
cardiogenic shock. Computed tomography (CT) showed high density in the
distal branches of both pulmonary arteries and a high density in the
right heart.Combined with the history of surgery, the clinician
considers the foreign body as bone cement and the diagnosis was ICE. The
bone cement in the heart was removed under emergency cardiopulmonary
bypass. The patient recovered and was discharged smoothly.

Toplumsal Bellek Mekanı Olarak Yapraklı Takvimler: 2020 Türkiye Takvimi Üzerine
Authors: Çiftçi Dilan
Published: March 2021

Toplumsal bellek sosyal bilimlerin hemen her alanında önemli bir olgu olarak yerini almaya başlayarak 1980’lerden bu yana pek çok araştırmada farklı bağlamlarda ele alınmıştır. Bu çalışmada toplumsal bellek kavramı üzerinden yürütülen tartışmalar tarihsel zaman ve hatırlatıcı mesajlar çerçevesinde yapraklı takvimler üzerinden devam etmiştir. Takvim ve özellikle yapraklı takvimler basılmaya başladığından bu yana genellikle her güne özel bilgilendirici ve hatırlatıcı mesajlar içermesi bakımından önemli bellek mekanları olarak kabul edilmiştir. Yapraklı takvimlerin de kendine has ideolojileri ile hatırlattıkları tarihsel zamanlar bu çalışmada Türkiye gazetesinin sunduğu yapraklı takvim üzerinden yürütülmüştür. Rastgele örneklem tekniği ile seçilen 2020 yapraklı takvimin hatırlatıcı mesajları 26 (yirmi altı) farklı kategoride incelenmiştir. Araştırmada öne çıkan temel bulgu hatırlatıcı mesajların çoğunlukla dini içerikli olduğu yönünde olmuştur. Bunun yanında yapraklı takvimler yıldönümleri ve anmalar noktasında da önemli bellek belgeleri sunan malzemeler olarak 2020 yapraklı takviminde de ortaya konmuştur.
"Mâni'u'n-Nukûş" ve Klâsik Türk Şiirinde Duvar Yazısı: "Âh Şâhum"
Authors: Uğur KARADENİZ Mustafa
Published: March 2021

Duvarlar; âşıklar, dertliler ve protestocuların kendi mesajlarını iletmek için kullandıkları bir iletişim aracına dönüşmüştür. Duvar yazılarının önüne geçmek için vakıfların, kendi bütçelerinde özel bir tahsisatla görevlendirdikleri “mâni’u’n-nukûş” adı verilen bir personeli bulunmaktadır. Klâsik Türk şiirinde âşıkların da duygularını duvar yazıları ile dile getirdikleri bilinmektedir. Duvarlara çeşitli renklerle yazılar yazan âşıkların bu eyleminin yaygınlığı, duvar yazıları ile ilgili bir jargon oluşmasından da anlaşılmaktadır. Bu manada duvar yazılarının birçok şiire konu olduğu görülmektedir. Bazı mısralar duvarlara yazıldığı gibi bazen duvar yazıları da mısralarda yer alabilmektedir. Âşık veya dertlilerin han, kervansaray gibi konaklama mekânlarının ya da cami, hamam ve imaret gibi yapıların duvarlarına sıla hasretlerini, sevgi ve özlemlerini, acılarını, dertlerini dile getiren şiir veya başkaca cümleler yazdıkları bilinmektedir. Çileli âşıklar, aşkın ıstırabını ve sevgililerine olan bütün hislerini, en özlü biçimde ifade etmeye yarayan bir ünlem bulmuşlardır: “âh şâhum”. Bir acı çekme ünlemi olmakla birlikte şiirde kazandığı birçok çağrışımı da yeniden hatırlatan “âh” nidasıyla başlayan bu yakarış, aşkın onulmaz dertlerin kaynağı olduğunu ve aşığın son bir feryatla sevdiğinden yardım umduğunu ifade eder ve “bana acı ey sultanım!” olarak da çevrilebilir.
Dîvân-ı Hikmetin Bilinmeyen Bir Yazması ve Onda Bulunan Yeni Hikmetler
Authors: Rezaei Mehdi
Published: March 2021

Ahmet Yesevî, Türk kültürü ve edebiyatı üzerinde ciddî etkisi olan şairlerden biridir. Yesevî, yüzyıllar boyunca Türk dünyasında birçok şaire ilham kaynağı olmuş, sufiyane şiirde yol gösterici şair olarak rol oynamıştır. Günümüze kadar Dîvân-ı Hikmet'in değişik nüshaları bulunmuş ve bu nüshalara dayanarak eserin farklı baskıları yayımlanmıştır. Mihmannâme-yi Buhara gibi tarihî kaynaklarda Dîvân-ı Hikmet'in eski yazmalarından söz edilmişse de elimizdeki yazmalar çoğunlukla on dokuzuncu yüzyılda istinsah edilmiştir. Birbirinden farklılıklar gösteren bu yazmalarda genellikle diğer şairlerden de hikmetler bulunmaktadır. Bu çalışmada Dîvân-ı Hikmet'in İran Millî Kütüphanesi'nde saklanan yeni bir yazması üzerinde durulmuştur. Yazmanın özelliklerinden bahsedilmiş, gereken durumlarda yayımlanmış diğer yazmalarla karşılaştırılmıştır. 190 sayfadan oluşan bu yazma, günümüze kadar neşredilmiş yazmalardan bazı farklılıklar göstermekte, diğer yazmalarda görülmeyen kimi hikmetleri içermektedir. Mahlaslarından dolayı Yesevî'ye ait olmadığı anlaşılan 10 hikmet dışında elimizdeki yazmada 60 hikmet ve bir münacat bulunmaktadır. Bu hikmetlerin 16'sı yeni hikmetlerden ibarettir. Yaklaşık 370 beyitten oluşan söz konusu yeni hikmetler, hiç kuşkusuz Dîvân-ı Hikmet'e yeni bir boyut kazandıracaktır.

Published: March 2021

Kosova Türklerinin yaşadıkları kültür coğrafyasında yaygın olarak kullanılan sevimli (hipokoristik) adlar, kültürel etkileşim yoluyla Kosova Türklerinde de normal kullanım alanı bulmuştur. Sultan İkinci Murat zamanında Anadolu’dan iskân ettirildiği düşünülen Kosova Türklerinin etnik ve kültür kökeni Anadolu’ya dayanır. Bu nedenle Kosova Türklerinin kültür ve folklorunda Anadolu’dan getirdikleri mirasın izleri görülür. Bu mirasın izlerini özel ve kamusal yaşamın her alanında görmek mümkündür ve buna ilişkin hatırı sayılır araştırma yapılmıştır. Kosova Türkleri bu kültürel mirası buralara yerleşip bu toprakların yerli unsuru haline geldikten sonra yerel kültür ve folklor unsurlarıyla zenginleştirmiştir. Kosova Türkleri folklorunun bu yönü henüz araştırılmamıştır ve araştırılmaya değerdir. Kültürel karışmanın sonucunda folklorik bir özellik olarak kişi adlarına sevimli (hipokoristik) ad üretme geleneği gelişmiştir.
Kosova Türklerinin adbilimi ile ilgili çalışmalar sınırlıdır ama yok değildir. Fakat hem terim hem olgu olarak sevimli (hipokoristik) ad, çalışılmış bir konu değildir.
Çalışmamızda terimin anlamı ve kökeni hakkında kısaca durulmuştur. Devamında Kosova Türklerinde sevimli (hipokoristik) ad yapma yolları hakkında bilgilere ve cinsiyete bağlı olarak yaygınlık kazanmış sevimli (hipokoristik) ad örneklerine yer verilmiştir. Bu çalışmada Balkan Türkleri kişi adları açısından önem arz eden bu sözcüklerin nereden geldiklerine ışık tutulmaya çalışılmıştır.

A melhoria na qualidade de vida tem sido uma das necessidades da sociedade nos últimos anos, refletindo principalmente na alimentação, com a inserção de alimentos funcionais, ressaltando-se os probióticos. A cultura de Kefir é um exemplo de probiótico natural, composto pela simbiose de microrganismos que pode ser consumida com adição de frutas como o açaí. O objetivo deste trabalho foi avaliar as características microbiológicas da polpa de açaí utilizada no cultivo do Kefir, bem como análise de pH, Sólidos Solúveis Totais (SST) e crescimento microbiano no fermentado obtido em culturas de 24, 48, 72 e 96 horas. Foram analisadas 5 diferentes concentrações de polpa de açaí, 0% (controle), 25%, 50%, 75% e 100%. Os resultados da análise microbiológica mostraram que a polpa de açaí estava apta para ser utilizada, os valores de pH e ºBrix se mantiveram constantes durante o período avaliado, semelhante ao encontrado na literatura. A contagem de microrganismos em câmara de Neubauer permitiu a visualização de maior número de bactérias quando comparada com as Leveduras e fungos filamentosos. Em 24 horas, o maior crescimento microbiano foi observado na amostra 3 contendo 50% de polpa de açaí; em 96 horas todas as amostras tiveram grande crescimento, com destaque para a que continha 25% de polpa de açaí. Dessa forma a adição de polpa de açaí favoreceu o crescimento da colônia de Kefir, sendo um potencial, a partir de mais pesquisas, para a fabricação industrial de um novo produto de valor agregado, saudável, natural e regional.

Authors: QUEMELLI Catharini Andreatta , NOGUEIRA Guilherme Bicalho
Published: March 2021

O presente estudo teve como objetivo analisar as sobras sujas e o resto ingesta de uma Unidade de Alimentação e Nutrição (UAN) com o intuito de reduzir o desperdício de alimentos, utilizando como método a pesagem da sobra e do resto ingesta antes e após a campanha educacional com os servidores. O resultado encontrado no resto ingesta antes da campanha era de 7,15%, correspondente a 48,2g/servidor. Após a campanha contra o desperdício, o resto ingesta foi reduzido para 4,62%, o equivalente a 28,6g/servidor, a redução demonstra os efeitos positivos da Campanha de Sensibilização. Já quando se avaliou os resultados das sobras sujas percebeu-se uma elevação nas taxas de 5,04% para 7,66%, que foram justificadas pela redução do resto ingesta dos comensais e pela ausência de treinamentos e campanhas voltadas para os funcionários.

São altos os níveis de desperdício em Unidades de Alimentação e Nutrição (UANs), assim como a geração de resíduos orgânicos. Dessa forma, a sustentabilidade pode ser empregue por meio do aproveitamento integral dos alimentos. O objetivo foi descrever os procedimentos metodológicos para elaboração de receituário padrão - na forma de e-book - destinado ao aproveitamento integral dos alimentos. O trabalho foi realizado em três etapas, sendo a primeira levantamento bibliográfico nas bases de dados SciELO e Bireme. A partir disso, foram selecionados os trabalhos que identificaram as partes dos alimentos que são consideradas como não comestíveis, tendo por fim, a criação de um e-book com receitas contendo estes alimentos. As partes não aproveitáveis dos alimentos podem ser utilizadas enfatizando o enriquecimento alimentar, diminuindo o desperdício e aumentando o valor nutricional das refeições. O uso dos alimentos de forma sustentável reduziria a produção de lixo orgânico e traria outros benefícios, como promover a segurança alimentar, prolongar a vida útil dos alimentos, beneficiar a renda familiar e além disso, o consumo de partes dos vegetais como cascas, sementes e talos eleva a ingestão de fibras, vitaminas, minerais e compostos bioativos. O aproveitamento integral dos alimentos mostra-se como alternativa de baixo custo e fácil aplicação, considerando que as partes desprezadas são ricas em nutrientes e compostos importantes para saúde e qualidade de vida dos indivíduos. Assim, a elaboração do e-book com receitas poderá ser utilizado nestes locais a fim de promover a sustentabilidade e reduzir a produção de resíduos orgânicos.
LEUCEMIA MIELOIDE E LINFOIDE: TAXA DE MORTALIDADE NO ESTADO DO PARÁ-BRASIL ENTRE OS ANOS DE 2000 E 2017
Authors: Weber Douglas Mroginski
Published: March 2021

As leucemias são neoplasias hematopoiéticas heterogêneas, podendo ser classificadas em mieloides e linfoides de acordo com a linhagem celular acometida, e subdivididas em agudas e crônicas. Estudos conduzidos em outros países e no Brasil evidenciam, diminuição de sua mortalidade e aumento da sobrevida. O objetivo do presente estudo foi avaliar as taxas de mortalidades por leucemias no estado do Pará em crianças, adolescentes, adultos e idosos.

The objective of this study was to estimate the height of roughness element (ZH) and zero-displacement length (Zd) for Baghdad city using remote sensing and GIS techniques and resources such as DEM, DSM, and shapefile. The difference between DEM and DSM produced digital height model which represents the height of the roughness element for the region, which was used to determine the zero-displacement height. The results showed that the variations in Zd values depend strongly on ZH. Rusafa had the highest Zd (15.8 m) while Dora had the lowest values (4.7 m). Thus, Baghdad city has medium density classification according to the results of Zd and ZH values.
Estimating gaseous pollutants in the air near Daura Refinery, Daura Power Plant and South of Baghdad Power Plant by calculating the fuel discharge
Authors: Roomi Thaer O. , Abed Adel S.
Published: March 2021

This study addresses estimation of emission rates and concentrations of SO2, CO and NO2 gases emitted from Daura Refinery (DR), Daura Power Plant (DPP) and South of Baghdad Power Plant (SBPP) by calculating the fuel discharge. The estimations were made by using the Gaussian plume model of dispersion at distances within 10 km from the pollution source for January, April, July and October 2017 under two stability conditions, slightly stable and moderately unstable. The effect of wind speed and direction as well as the ambient temperature of the surrounding air on the dispersion and transmission of air pollutants were also investigated. It was found that the unstable conditions are better for dispersing out atmospheric pollutants. The results showed that Zafarania District was the most affected by pollutants emitted from DR and BSPP while Daura District was more affected by DPP due to the prevailing wind direction. It was also found that an increase in wind speed leads to a decrease in the concentration of pollutants. The concentration of pollutants is inversely proportional to the height of the chimney, the speed of the gas leaving the chimney, while it is directly proportional to the diameter of the chimney. DPP has higher emission rates than DR and SBPP while at the surface level, the pollutants concentrations emitted from DR are greater than those emitted from DPP and SBPP.

Different techniques were employed for the passage of different utilities through structural elements. The reduction of the overall building weight was the main concern that needs to be achieved, especially for a multistory building. It can be done with the eliminating of a suspended ceiling with a portion of the beam’s weight by taking the advantages of the hollow sections. In this study, an equivalent reinforcement to the traditional ribbed reinforcement was employed to fabricate a reinforced concrete (RC) beam with a hollow section along the length of the beam. A steel pipe was used based on the equivalent moment from section analysis. Two diameters were selected of steel pipes as an equivalent to the commercial reinforcement. A total of four RC beams were cast and tested, two of them with traditional reinforcement and the other with steel pipe reinforcement. The comparison showed a promising result in terms of ductility, cracking pattern, ultimate strength, and mode of failure compared to the reference beam. The peak loads for the specimens with steel pipe were 160.6 kN and 184 kN, while they were 192 kN and 203.5 kN for the beams with traditional reinforcement.

This paper presented a strengthening technique for enhancement reinforced concrete (RC) slab-column connection behavior using steel plates and steel stiffeners. A bi-axial load was applied with an eccentricity of 150 mm in both x and z directions. Four specimens with dimensions of 1,600 × 1,600 × 100 mm were tested in this research. The steel plate dimensions were chosen to be 600 × 600 and 800 × 800 mm with 6 mm thickness. The steel stiffeners are used to support and enhance the steel plate that it is extended from column to the slab-column connection with different dimension. The results showed an improvement in the stiffness of slab and increasing in the ultimate capacity. Also, when the steel plates dimensions increased, the ultimate capacity and stiffness increased.

The method for the choice of rational regimes of traffic light control is developed based on the minimization of the number of violations the requirements of traffic light signals by pedestrians depending on the volume-capacity ratio of traffic lanes and control of vehicular queue on the approach to the stop-line. Assessment of rationality is carried out considering the simultaneous impact of such factors as roadway volume-capacity ratio, traffic light restrictive signal duration, the number of violations of the traffic rules by pedestrians, and maximal queue length of vehicles. The model of the change of the number of violations of the rules of crossing the roadway by pedestrians depending on the volume-capacity ratio of different intersection types is developed in this paper. The model of determining the maximal vehicular queue length before intersections depending on the volume-capacity ratio and the share of the restrictive signal on the lane in the control cycle is developed. Recommendations about the choice of rational regimes of traffic light control depending on traffic delay, planning parameters of the road network, and pedestrian behavior are proposed.

The development of an ecofriendly binder containing high volume of cement replacement by incorporating two waste materials for the use in soil stabilization. This paper investigates the possibility of replacing ordinary Portland cement (OPC) by two waste and by-product materials for the use of a silty clay soil stabilization purpose. The soil was treated by 9.0% OPC where this mixture was used as a reference for all tests. Two by-product materials: ground granulated blast furnace slag and cement kiln dust were used as replacement materials. Consistency limits, compaction and unconfined compression strength (UCS) tests were conducted. Scanning electron microscopy (SEM) analysis was carried out for the proposed binder to investigate the reaction of products over curing time. Seven curing periods were adopted for all mixtures; 1, 3, 7, 14, 28, 52, and 90 days. The results showed that the strength development over curing periods after cement replacement up to 45–60% was closed to those of the reference specimens. The microphotographs of SEM analysis showed that the formation of Ettringite and Portladite as well as to calcium silicate hydrate gel was obvious at curing periods longer than 7 days reflected that the replacing materials succeed to produce the main products necessary for binder formation.

Published: March 2021

Nature friendly technologies in today’s world are the subject of scientific research and the interest of local authorities and the residents themselves. In the context of the city, one of the most important issues is the neutralization of air pollution generated by transport and heating of the premises with the use of solid fuels. The article analyses differences of the response of traditional and photocatalytic paving stones. We analysed water absorption, frost resistance, tensile strength at splitting and abrasion of paving stones. It has been proved that paving stones exposed to atmospheric factors and pollution during one heating season met the assumed quality criteria. In addition, the results obtained for the characteristics analysed were higher than the results of samples tested in laboratory conditions. The results also indicate a slight advantage of photocatalytic cubes in terms of their resistance to abrasion and tensile strength at splitting. Traditional and photocatalytic paving stones withstand well the operating conditions. It seems that products based on TioCem® cement are the future implementation of pedestrian and traffic routes.

A novel application of building demolition waste for removal benzene from aqueous solutions. In this research, demolition waste from buildings has been studied for possible use as benzene removal adsorbent from aquatic solution. The effect of adsorbent dosage, contact time, initial benzene concentration, and initial pH on benzene adsorption capacity have been investigated in the batch adsorption experiments. The adsorption effects initially happened very rapidly and achieved equilibrium within 180 min. Benzene removal was observed to decrease by an increase in the initial concentration of benzene of 300–700 mg·L–1, an increase in the adsorbent dose of 0.4–2.4 g per 100 mL, where an optimum adsorbent dose equal to 1.2 g per 100 mL was found. The potential of adsorption increases with pH 3.0–7.0 to reach the maximum removal efficiency at pH 6.0. The findings showed that equilibrium data were adequately adapted and correlated with the Freundlich isotherm models. The average percentage of the removal at room temperature was about 98%. Results suggest that building demolition waste can be used effectively in industrial wastewater treatment for the removal of aromatic hydrocarbon, benzene, as a low-cost option.

Published: March 2021

Biocompatibility has been a major concern in the field of medical implants, and the “stress shielding” effect can be detrimental to the growth of bone cells. In this work, a parametric irregular porous structure model based on bionics design was established. The influence of different parameters on the elastic modulus, compressive strength, average pore size, and porosity was investigated. An optimization model using the grey relational analysis was established by controlling the irregularity, seed points, and strut diameter. With the goal of meeting biological requirements, the optimization results showed that the elastic modulus decreased by 40.21% and the porosity increased by 17.58%. Irregularity had little effect on the elastic modulus, porosity, and average pore size, and it was negatively correlated with compressive strength. The strut diameter and seed points were positively correlated with the elastic modulus and compressive strength but negatively correlated with the porosity and average pore size, and the seed count had the largest impact. By adjusting these parametric models, the optimization factors were obtained based on the elastic modulus, porosity, average pore size, and compressive strength of human bone. These results provide theoretical guidance for studying the mechanical properties of irregular porous structures fabricated via selective laser melting.
