This paper explores the role of firm boundaries by abstracting from the property rights approach, which is not applicable to the increasingly important human-capital intensive firms. By focusing on firm boundaries’ role as ‘information barriers’ that blur employees’ individual outside identities, we find that firms boundaries matter because they can alter investment specifity and hence alleviat...

INTRODUCTION Currently there are several advanced guiding techniques for pathoanatomical diagnosis of incidental solitary pulmonary nodules (iSPN): Electromagnetic navigation (EMN) with or without endobronchial ultrasound (EBUS) with miniprobe, transthoracic ultrasound (TTUS) for needle approach to the pleural wall and adjacent lung and computed tomography (CT) -guidance for (seldom if ever use...

Böbrek taşlarının medikal görüntülerdeki teşhisi ve tespiti hastalığın seyri tedavi yönteminin belirlenmesi açısından önemlidir. Abdominal Bilgisayarlı Tomografi (BT) görüntülerinin gürültülü düşük çözünürlükte olması böbrek taşı teşhisini zorlaştıran faktörlerdir. Bu çalışmada abdominal BT görüntülerinde bulunan böbreklerdeki taşların sınırlarının sayılarının amaçlanmıştır. İlk olarak netleşti...

Abstract The PSA test is used primarily to screen for prostate cancer. A measures the amount of prostate-specific antigen (PSA) in your blood. a protein produced prostate, small gland that sits below man's bladder. mostly found semen, which also prostate. Small amounts ordinarily circulate can detect high levels may indicate presence However, many other conditions, such as an enlarged or inflam...

5'-deoxy-5'-methylthioadenosine phosphorylase (MTAP) catalyzes the phosphorolytic cleavage of 5'-deoxy-5'-methylthioadenosine (MTA), a byproduct of polyamine biosynthesis. The Sulfolobus sulfataricus genome encodes two MTAPs. SsMTAP I has broad substrate specifity, accepting guanosine, inosine, adenosine and MTA, while SsMTAP II is specific for MTA. SsMTAP I forms a donut-shaped hexamer, while ...

Sensitivity, specifity, high time resolution and cost effective simultaneous measurements of several components using operational systems are the main requirements for atmospheric research and air pollution monitoring. Tunable diode lasers absorption spectroscopy (TDLAS) is increasingly beeing used to measure atmospheric trace gas concentrations down to low ppb-levels volume mixing ratio). This...

Background Pseudomonas aeruginosa is an important opportunistic pathogen causing serious pulmonary, urogenital and systemic infections. P. aeruginosa injects four effector proteins into host cells via the type III secretion system. ExoY is one of these proteins. ExoY was originally classified as adenylyl cyclase with homology to the typical calmodulin-stimulated adenylyl cyclase exotoxins CyaA ...
