Bu çalışma, armut ağaçlarının bulunduğu topraklarda çeşitli bor fraksiyonlarının araştırılması amacıyla yapılmıştır. amaçla Türkiye'nin Bursa yöresindeki “Deveci” ve “Santa Maria” (Pyrus communis L.) bahçeleri ziyaret edilmiştir. Toprak örnekleri 0-30 cm 30-60 den alınmıştır. Ayrıca meyve yaprak numuneleri de toplanmıştır. Toplam toprak boronunun en büyük oranı kalıntı formda (% 94.28-94.51) me...

The ability to chunk, or to strategically organize, information is one of the most powerful ways people have to encode experience into memory. A functional brain imaging study by Bor and colleagues, in this issue of Neuron, provides evidence that prefrontal cortex contributes to this essential mnemonic process.

In this paper, we establish a new theorem on | A, pn |k summability factors of Fourier series using matrix transformation, which generalizes a main theorem of Bor [6] on ∣∣N̄, pn∣∣k summability factors of Fourier series. Also some new results have been obtained.

Altered sympathetic nervous system activity has been implicated often in hypertension. We examined short-term potentiation [posttetanic potentiation (PTP)] and long-term potentiation (LTP) in the isolated superior cervical ganglia (SCG) from Sprague-Dawley (SD) rats given vehicle, digoxin, or ouabain by subcutaneous implants as well as in animals with ouabain-induced hypertension (OHR), and inb...

BACKGROUND Sediment bacterial communities are key players in biogeochemical cycling of elements in the aquatic environment. Copper mining, smelting, and processing operations located in Bor area (Serbia) are major environmental hot spots in the lower Danube Basin and Western Balkans. In the present study, we evaluate the influence of trace element (TE) concentration in sediments and physico-che...

We prove a general theorem on |N̄,pn;δ|k summability factors, which generalizes a theorem of Bor (1994) on |N̄,pn|k summability factors, under weaker conditions by using an almost increasing sequence. 2000 Mathematics Subject Classification. Primary 40D15, 40F05, 40G99.

We prove the following theorems: 1. There exists an ω-covering with the property s0. 2. Under cov(N ) = 2 there exists X such that ∀B∈Bor[B ∩ X is not an ω-covering or X \B is not an ω-covering]. 3. Also we characterize the property of being an ω-covering.

Bu çalışmada, kolemanit, üleksit ve tinkal takviyeli epoksi kompozitlerin yoğunluk, Shore D sertliği, aktivasyon enerjisi ısıl iletkenlik katsayıları incelenmiştir. Bor fabrikasında alınan bileşenler -100/200 mesh partikül boyutuna öğütülmüş 105 °C'de 2 saat etüvde kurutulmuş dolgu olarak hazırlanmıştır. Epoksi reçinesine kütlece farklı oranlarda maddeleri eklenerek kompozit malzemeler elde edi...
