Kentsel açık yeşil alanların temel bileşeni olarak bitkiler sadece estetik görünüşleri ile değil sağladıkları ekosistem hizmetleri ile de son derece önemlidirler. Bitkilerin kendilerinden beklenen ...faydaları sağlayabilmeleri için sahip oldukları özelliklerin bilinmesi ve bitkisel tasarımın doğru planlanıp uygulanması gerekir. Kentsel açık ve yeşil alanların tasarımında seçilen bitki taksonları hem fizyolojik hem de morfolojik özellikleri ile bir bütün olarak değerlendirilmelidir. Dolayısı ile kentlerde yapılacak bitkisel tasarım çalışmalarında kullanılacak olan bitki materyalinin sahip olduğu estetik özelliklerin yanı sıra aromatik özellikleri, zehirlilik durumları ve insanlar üzerinde alerjik reaksiyonlara neden olabilecek polen yayma özelliği gösterme durumları incelenmeli ve bu doğrultuda seçimler yapılmalıdır. Çalışma kapsamında Şanlıurfa ili Haliliye ilçesi açık ve yeşil alanlarında 85 bitki taksonu tespit edilmiştir. Bu bitkiler; yaşam formu, yaprak durumu, çiçeklenme zamanı, aromatik özellikleri, zehirlilik durumları ve alerjen oranları bakımından değerlendirilmiştir. Bu değerlendirme sonucunda doğal bitki kullanımının kısıtlı kaldığı, yaprak döken ve herdemyeşil bitki türlerinin dengeli kullanıldığı ve aromatik bitki çeşitliliği bakımından önemli bir zenginlik olduğu tespit edilmiştir. Ayrıca, açık yeşil alanlarda çok sayıda alerjen bitki kullanılmasının yanı sıra önemli sayıda zehir ihtiva eden bitki taksonu olduğu belirlenmiştir. Sonuç olarak tespit edilen bitki türlerinin bitkisel tasarım çalışmalarında kullanımları ile ilgili çeşitli öneriler geliştirilmiş ve açık yeşil alanlarda yapılan gözlem notları paylaşılmıştır.
As the basic component of urban open green areas, plants are extremely important not only with their aesthetic appearance but also with the ecosystem services they provide. In order for plants to provide the expected benefits from them, their characteristics must be known and the planting design must be planned and applied correctly. The plant taxa selected in the design of urban open and green areas should be evaluated as a whole with both their physiological and morphological characteristics. Therefore, in addition to the aesthetic properties of the plant material to be used in planting design studies to be made in cities, its aromatic properties, toxicity status and pollen spreading properties that may cause allergic reactions on humans should be examined and choices should be made accordingly. Within the scope of the study, 85 plant taxa were identified in the open and green areas of Haliliye district of Şanlıurfa province. These plants were evaluated in terms of life form, leaf condition, flowering period, aromatic properties, poisonous parts and allergen rates. As a result of this evaluation, it was determined that the use of natural plants was insufficient, deciduous and evergreen plant species were used in a balanced way, and there was an important richness in terms of aromatic plant diversity. In addition, it has been determined that there are a significant number of plant taxa containing poison, as well as the use of many allergenic plants in open green areas. As a result, various suggestions were developed regarding the use of plant species in planting design applications, and observation notes made in open green areas were shared.
Objectives:
The aim of this study is to identify the epidemiological, clinical, and laboratory features of coronavirus disease 2019 (COVID-19) in children.
Methods:
A retrospective study was ...conducted by pediatric infectious disease specialists from 32 different hospitals from all over Turkey by case record forms. Pediatric cases who were diagnosed as COVID-19 between March 16, 2020, and June 15, 2020 were included. Case characteristics including age, sex, dates of disease onset and diagnosis, family, and contact information were recorded. Clinical data, including the duration and severity of symptoms, were also collected. Laboratory parameters like biochemical tests and complete blood count, chest X-ray, and chest computed tomography (CT) were determined.
Results:
There were 1,156 confirmed pediatric COVID-19 cases. In total, male cases constituted 50.3% (
n
= 582) and females constituted 49.7% (
n
= 574). The median age of the confirmed cases was 10.75 years (4.5–14.6). Of the total cases, 90 were younger than 1 year of age (7.8%), 108 were 1–3 years of age (9.3%), 148 were 3–6 years of age (12.8%), 298 were 6–12 years of age (25.8%), 233 were 12–15 years of age (20.2%), and 268 cases were older than 15 years of age (23.2%). The most common symptom of the patients at the first visit was fever (50.4%) (
n
= 583) for a median of 2 days (IQR: 1–3 days). Fever was median at 38.4°C (38.0–38.7°C). The second most common symptom was cough (
n
= 543, 46.9%). The other common symptoms were sore throat (
n
= 143, 12.4%), myalgia (
n
= 141, 12.2%), dyspnea (
n
= 118, 10.2%), diarrhea (
n
= 112, 9.7%), stomachache (
n
= 71, 6.1%), and nasal discharge (
n
= 63, 5.4%). When patients were classified according to disease severity, 263 (22.7%) patients were asymptomatic, 668 (57.7%) patients had mild disease, 209 (18.1%) had moderate disease, and 16 (1.5%) cases had severe disease. One hundred and forty-nine (12.9%) cases had underlying diseases among the total cases; 56% of the patients who had severe disease had an underlying condition (
p
< 0.01). The need for hospitalization did not differ between patients who had an underlying condition and those who do not have (
p
= 0.38), but the need for intensive care was higher in patients who had an underlying condition (
p
< 0.01). Forty-seven (31.5%) of the cases having underlying conditions had asthma or lung disease (38 of them had asthma).
Conclusions:
To the best of our knowledge, this is one of the largest pediatric data about confirmed COVID-19 cases. Children from all ages appear to be susceptible to COVID-19, and there is a significant difference in symptomatology and laboratory findings by means of age distribution.
In this study, some morphological, physiological and chemical properties of the Rosa chinensis Jacq. 'Viridflora' taxa, which does not form petals due to a flower anomaly called phlloidi and is ...called 'Green rose' only because of the long and green sepals it forms, were discussed. In this context, plant growth characteristics, leaf characteristics, stomatal morphology, proportional water content of leaves, chlorophyll contents of leaves and micro and macro nutrient content of leaves were determined. As a result of the study, it was determined that the 'Green rose' plant, which was compared with different Rosa taxa, had a broad/upright structure, the average leaf area was 17.17 cm2, the average pedicel length was 1.45 cm, the proportional water content of the leaf was 77.42%, and the chlorophyll amount was 40.87. It was concluded that the leaves of R. chinensis 'Viridflora' plant had average values in stomatal morphology parameters. In line with reference values, nitrogen, phosphorus and manganese values were found to be low in Yeşilgül leaves, while boron and calcium values were found to be high. Potassium, magnesium, copper and iron contents were within the reference range.

Giriş: Yeni ortaya çıkan patojenlerin neden olduǧu salgınların erken dönemleri saǧlık çalışanları için büyük bir risk taşımaktadır. SARS-CoV-2'nin neden olduǧu pandemide de durum farklı olmamış, ...alınan yetersiz önlemler ve kişisel korunma eksikliǧi nedenleriyle pandemi başlangıcında birçok saǧlık çalışanı hayatını kaybetmiştir. Saǧlık çalışanlarının koruması ve güvenli ortamda çalışmalarının devamlılıǧının saǧlanması saǧlık hizmetlerinin aksamamasının yanında salgının sınırlandırması içinde gereklidir. Kişisel koruyucu ekipmaların kullanımı ile ilgili eǧitimlerin verilmesi, gerekli durumlarda güncellenmesi koruyucu ekipmanların saǧlanması kadar önemlidir. Gereç ve Yöntemler: Otuz iki farklı merkezde çocuklara saǧlık hizmeti veren 4927 saǧlık personeli üzerinde anket uygulanmış, kişisel koruyucu ekipman kullanımı konusunda alınan eǧitim deǧerlendirilmiş, yaş, cinsiyet, meslek ve bölgesel farklılıkların eǧitim alma üzerine etki edip etmediǧi deǧerlendirilmiştir. Bulgular: Otuz iki farklı merkezden 4927 saǧlık çalışanın katıldıǧı çalışmada, 4457 (%91) saǧlık çalışanın kişisel koruyucu ekipmaların kullanımı ile ilgili eǧitim aldıǧı saptanmış, yalnızca %36'sının hem teorik hem de uygulamalı eǧitim aldıǧı bulunmuştur. Meslek grupları arasında eǧitim alma yönünden fark görülmezken, bölgelere göre eǧitim alıp almamada anlamlı fark olduǧu saptanmıştır.
This study was carried out on some domestic and foreign late blooming varieties and their genotypes obtained as a result of hybridization in the almond collection parcel of Harran University Faculty ...of Agriculture in Sanliurfa/Turkiye in the summer period of 2020. In the research, 5 different cultivars and 6 hybrids were examined in the orchard. In the study, 3 trees of each variety and 9 leaves from 2 directions of each tree were taken. North and South directions were taken into account when taking leaf samples. According to the findings, when the leaf characteristics were examined in general, the highest values in terms of leaf width, leaf length, petiole length and leaf area were found in ‘Type-7’ hybrids among cultivars and hybrids. As a result of stoma analysis on the lower surface of the leaves, the highest overall average (196.47 unitsmm-²) was determined in Type-3, while the lowest (127.10 units/mm²) was found in ‘Ferragnes’ variety. As a result of the analysis, when all the average values were taken into account, it was determined that the leaf area was 16.74 cm², the average stomata density was 153.51/mm² and the leaf area was 256975.74/leaf stomata. It is thought that the study will be descriptive for almond varieties and hybrids grown in the same ecology.
Bu araştırma, Güneydoğu Anadolu Bölgesi'nin kurak ve yarı-kurak ekolojik koşullarına sahip Şanlıurfa ilinde iki ayrı bahçede yetiştirilen hünnap (Ziziphus jujuba Mill.) genotiplerinin meyve, yaprak ...ve stoma özelliklerinin belirlenmesi amacıyla 2021 yılında yürütülmüştür. Araştırmada incelenen hünnap genotiplerinde meyve ağırlığı 2.78-20.28 g, meyve boyu 21.77-39.47 mm ve meyve eni 18.62-37.23 mm, yaprak alanı 3.11-7.01 cm2, yaprak eni 1.31-2.65 cm ve yaprak boyu ise 3.29-5.09 cm arasında belirlenmiştir. Hünnap genotiplerinde stoma sayıları 323.30 adet mm-2 (kültür hünnap)-333.31 adet mm-2 (yabani hünnap), ortalama stoma boyu ve eni değerleri ise sırasıyla 27.22 (yabani hünnap)-28.00 µm (kültür hünnap) ve 18.21 (yabani hünnap)-20.05 µm (kültür hünnap) arasında tespit edilmiştir. Elde edilen bu sonuçlara göre daha küçük yaprak alanına sahip olan yabani hünnap genotipinin stoma sayısı, stoma eni ve boyu değerlerinin istatistiksel olarak kültür hünnap genotipinden farklılık göstermediği belirlenmiştir. Bu bakımdan, birim alandaki stoma yoğunluğunun diğer türlere göre daha fazla olması nedeniyle, hünnap bitkisinin kurak ve yarı-kurak ekolojilerde ağaçlandırma çalışmalarında başarılı olarak kullanılabileceği düşünülmektedir.
This research was carried out in 2021 to determine the fruit, leaf and stomata characteristics of jujube (Ziziphus jujuba Mill.) genotypes grown in two separate orchards in Şanlıurfa province, which has arid and semi-arid ecological conditions in the Southeastern Anatolia Region. In the jujube genotypes examined in the study; fruit weight was 2.78-20.28 g, fruit length was 21.77-39.47 mm, fruit width was 18.62-37.23 mm, leaf area was 3.11-7.01 cm2, leaf width was 1.31-2.65 cm and leaf length was 3.29-5.09 cm. In the jujube genotypes, the number of stomata is 323.30 units mm-2 (culture jujube)-333.31 units mm-2 (wild jujube), mean stomatal length and width are 27.22 (wild jujube)-28.00 µm (culture jujube) and 18.21 (wild jujube)-20.05 µm (culture jujube). According to these results, it was determined that the number of stomata, stomatal width and length values of the wild jujube genotype, which has a smaller leaf area, did not differ statistically from the culture jujube genotype. In this respect, it is thought that the jujube plant can be used successfully in afforestation studies in arid and semi-arid ecologies, due to the fact that the stomatal density per unit area is higher than other species.
In this study, an in vitro propagation protocol of Poncirus trifoliata L. (Raf.) rootstock, which is one of the main rootstocks used in citrus, was created. Monocular node parts of the plant, which ...is the source of explant, were cultured in MS nutrient media containing BAP at dissmilar concentrations (0.5-1.0-2.0 mg/l). Afterward, it was observed that shoot appearance and tillering were achieved in the node explants cultured in MS nutrient medium comprising 1.0 mg/l BAP. The shoots were removed to a new culture in MS nutrient media containing NAA and IBA for rooting. While 30% rooting was achieved in the rooting medium, 62% of the rooted plantlets were acclimated to external conditions. 2 mg/l BAP and 2 mg/l silver nitrate (AgNO3) doses were supplied to the MS medium. The results of this study were obtained and a compound was found to the yellowing and leaf fall problem. As a result, in vitro propagation of Poncirus trifoliata, which is among the important citrus rootstocks, was tried, and its rooting ability was investigated in different nutrient media concentrations after shoots were obtained from different explants.
