Land-use type and slope position effects on soil respiration in black locust plantations in Artvin, Turkey

In this study, influences of aspect, land-use type, and sampling time on soil respiration were investigated in black locust plantation and adjacent grassland sites in Murgul-Artvin, Turkey. Both sites were heavily affected from acid rain produced by a nearby copper smelter. Soil respiration was measured approximately monthly in three sampling plots in each sites from January 2005 to November 2005 using the soda-lime technique. Mean daily soil respiration ranged from 0.22 to 2.37 g C m-2 d-1. Mean soil respiration in black locust plantations and grassland sites were 0.74 and 1.03 g C m-2 d-1, respectively. Soil respiration was significantly higher in grassland sites than in black locust plantation sites. Seasonal changes in soil respiration were related to soil moisture and temperature changes. Mean annual soil respiration rate correlated positively with surface soil (0-15 cm) sand (P < 0.05) and organic matter content (P < 0.1), and correlated negatively with mean surface soil clay and silt contents (P < 0.1). Overall, our results indicate that grassland sites have higher soil biological activity compared to black locust plantation sites

The effect of biceps tenotomy on superior humeral migration in arthroscopic repaired full-thickness supraspinatus tears

Lesions of the long head of the biceps (LHB) tendon are a prevalent injury that frequently coexists with rotator cuff injuries. This study aimed to assess the effect of supraspinatus (SST) repair with concurrent LHB tenotomy on superior migration of the humeral head. The acromiohumeral distance (AHD) was determined via ultrasound to evaluate the superior migration of the humeral head. Methods: The study population was retrospectively recruited from patients who underwent unilateral arthroscopic repair of isolated degenerative full-thickness SST tears between January 2017 and December 2019. Patients were divided into 2 subgroups based on whether they underwent LHB tenotomies during arthroscopy. While 37 patients underwent arthroscopic single-row SST repair, the other 33 patients underwent arthroscopic single-row SST repair with LHB tenotomy. The subject group consisted of people who had undergone arthroscopic shoulder surgery. Contralateral shoulders without rotator cuff injuries were included in the control group. The AHD and SST thicknesses of patients were examined via the ultrasound in both groups and subgroups. Results: The mean age in the SST repair group was 55.52 ± 4.58 years (range, 46-63 years), whereas it was 58.24 ± 3.98 (range, 52-73 years) in the SST repair + LHB tenotomy group. In the SST repair group, 57.6% of patients were female and 42.4% were male, whereas 56.8% and 43.2% were in the SST repair + LHB tenotomy group, respectively. The mean body mass index was 28.06 ± 1.31 kg/m2 (range, 25.7-31.2 kg/m2) in the SST repair group and 28.95 ± 1.79 kg/m2 in the SST repair + LHB tenotomy group. Groups were not different for sex, surgery side, dominant side, tear size, and follow-up time; however, the SST repair + LHB tenotomy group had significantly higher mean age and body mass index than the SST repaired group. The mean AHD value and SST thickness were significantly less in both the rotator cuff repair group and the rotator cuff repair + LHB tenotomy group compared to the healthy shoulder. The mean AHD value was significantly lower in the SST repaired + LHB tenotomy group than in the SST repair group (P = .02). Conclusion: The AHD was narrowed in patients who underwent LHB tenotomy and radiologically demonstrated the depressor effect of the LHB tendon on the humeral head. As a secondary outcome, we demonstrated that regardless of tenotomy, AHD could not be restored in patients who underwent arthroscopic single-row SST repair

Determination of mothers’ depression levels by the type of special educational services they get for their autistic children

The purpose of this study is to determine the depression levels of mothers by the type of special educational services they got for their autistic children. Mothers of 20 male autistics and 5 female autistics participated in the study as volunteers. %24 of families got educational services from life coaches, %48 from O.Ç.E.M (Autistic Children Education Centers) and %28 from rehabilitation centers. Beck depression scale applied to volunteers to determine the depression levels (SCORES, Life Coach =16±7,05, O.Ç.E.M =13,83±7,05, Rehabilitation Center =25,57±9,28). Data were presented as mean, SD, frequency for description purpose. Variables were analyzed and were calculated by using Kruskal Wallis Test and Mann Whitney U tests. There is a significance difference at level of P&lt;0.05 (p=0,035) between parents which get different types of special educational services. As a result; significant difference has found in the depression levels of parents which get special educational services from rehabilitation centers found more depressive then O.Ç.E.M and life coach services.

Modelling of Adsorption Kinetic Processes—Errors, Theory and Application

Adsorption has become a competitive method in the field of wastewater and air treatment. Adsorption kinetics is one of the main factors that must be understood before the applicability of any adsorbent. In every adsorption process, linear or non-linear analysis of the kinetics is applied. The goodness of fit index (coefficient of correlation or sum of squares) is applied to access the best model. The usage of linear or non-linear from of the adsorption kinetics has an impact on the distribution of error function. Almost in every adsorption study, linear forms have been used to conclude the best kinetic model that influence the adsorption mechanism—which might be an error. Therefore, this review highlights the mistakes in the usage of linear and non-linear models. The applicability of the adsorption kinetics in wastewater treatment is also illuminated

Doğu Karadeniz Bölgesi’nde Organik Balık Yetiştiriciliği İmkânlarının Araştırılması

Araştırma Doğu Karadeniz Bölgesi’nde bulunan Artvin, Rize, Trabzon, Gümüşhane, Bayburt, Giresun ve Ordu illerini kapsamaktadır. Bölge illerinde kayıtlı bulunan, 3 ton/yıl kapasitenin üzerinde ve tatlı sularda (kaynak suyu ve dere suyu) alabalık yetiştiriciliği yapan işletmeler, organik su ürünleri üretimi açısından incelenmiştir. Sektörde organik tarım konusunda önemli bilgi eksikliği olduğu gözlenmiştir. Alabalık çiftliklerinde yapılan incelemeler sonucunda işletme sahiplerinin sadece %33 lük bir kısmı organik tarımı daha önce duyduklarını belirtmişlerdir. Ayrıca işletme sahiplerinin sadece % 4’ü organik su ürünleri yetiştiriciliğinden haberdar olduklarını belirtmişlerdir. İncelenen işletmelerin çok büyük bir kısmının (%91) yetiştiricilikle ilgili kayıt tutma özelliklerinin olmadığı görülmüştür. Gümüşhane, Artvin ve Rize (yüksek kesimler) illerinde diğer illerimize nazaran önemli sayılabilecek bir organik yetiştiricilik potansiyeli bulunmaktadır. Bu da işletmelerin bulundukları bölgelerin kirlilik kaynaklarından uzak bakir bölgeler olmasından kaynaklanmaktadır. Giresun ve Ordu illerinde bulunan bazı işletmelerin yoğun fındık tarımından dolayı tarımsal kirlilik (gübre-pestisit) riski altında bulundukları, özellikle fındık gübreleme dönemlerinde balık ölümleri görüldüğü bazı çiftlik sahipleri tarafından ifade edilmiştir. Ayrıca Trabzon, Rize, Giresun ve Ordu İllerimizin sahil kesimine yakın bölgelerde bulunan bazı işletmelerde, dere suyunun bulanması, ısınması ve çeşitli kirlilik problemleri nedeniyle yetiştiricilikte çeşitli sorunlar yaşandığı, diğer bölgelerden biraz daha yoğun hastalık görüldüğü gözlemlenmiştir. Arazi çalışmalarında, uygun potansiyel görülen işletmelerde yapılan su analizleri sonuçlarıyla, Dünya’da organik alabalık yetiştiriciliği ile ilgili su kalite kriterlerini belirten sertifikasyon kuruluşlarının değerleri karşılaştırılmış ve incelenen birçok işletmenin su özelliklerinin bu kriterleri sağladığı görülmüştür

Usefulness of the uric acid and CHA2DS2-VASc score in prediction of left atrial thrombosis in patients with mitral stenosis and sinus rhythm

Background: The risk of thrombus formation in the left atrium is known to be very high in patients with both mitral stenosis (MS) and atrial fibrillation (AF). However, that risk should not be ignored in patients with MS in sinus rhythm (SR). The aim of this study was to determine the clinical, echocardiographic, and biochemical factors that could have a determining role in the formation of a left atrial (LA) thrombus in patients with MS in SR. Method: A total of 207 consecutive patients with MS who underwent both transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) for diagnosis or to investigate the presence of a thrombus in the LA and appendage were enrolled in this study. Results: LA thrombus was detected in 21 of 207 patients. CHA2DS2-VASc score was not found to be a predictor of LA thrombosis in patients with MS in SR, despite the higher CHA2DS2-VASc scores observed in those patients. The mitral valve area and mitral valve gradient were not predictive of LA thrombus development; however, LA anteroposterior diameter (LAAPD) was found to be a predictor of LA thrombosis. Levels of high sensitivity-C-reactive protein and uric acid were higher in the patients with LA thrombosis, but only uric acid was found to be a predictor of LA thrombosis in multivariate analysis. Conclusions: A larger LAAPD and an elevated serum uric acid level were found to be independent predictors of LA thrombosis in patients with MS in SR.

Assesment of patient's perspective on treatment free remission in CML: A Turkish multicenter cohort

Treatment free remission (TFR) is one of the main goals of therapy in Chronic Myeloid Leukemia (CML). Patient perspective and expectations have an indicative effect on discontinuation decisions. We analyzed 116 CML patients' perspective on TFR and factors that associated with willingness for tyrosine kinaz inhibitor (TKI) discontinuation from four different center in Turkey based on a national survey. Patients in our cohort had 7.8% awareness of TFR and after brief information willingness to attempt TFR has been reached to 58.9% in all population. Shorter disease duration was associated with enhanced willingness to attempt discontinuation in multivariate analyses (p=0.031). Most common patient related limitation for TKI discontinuation decision was anxiety about disease relaps and TKI resistance. Even disease relaps in TFR means molecular and detectable with close monitoring, patients still had considerable concerns about TKI discontinuation
