This paper studies the possibility of minimizing energy consumption during 35/50 bitumen storage. Similarly to most companies, company with which we collaborated uses fossil fuel maintain tanks at 150 °C. The main objective is optimize usage. To achieve this purpose, tested two new storage processes. One based on dynamic temperature between 140 and 160 °C, other room conditions. work evaluates ...

Background: Fine needle aspiration biopsy (FNAB) is usually used to distinguish the malignant and benign nodules. Applying a biopsy needle evokes a sense of fear and pain in the patients. Although some studies refute the usefulness of local anesthesia (LA) prior to fine needle aspiration biopsy, it is still debatable. This prospective cross-sectional study intended to evaluate the effect of LA ...

A novel procedure using a polyurethane transducer-tipped catheter (Millar) is described that allows reliable measurement of interstitial fluid pressure (IFP) in cancer tissues. Before and after each use, the transducer is calibrated at 37-C by a water column. After calibration, the transducer is passed through the lumen of a surgical needle. The sensor is kept in the lumen of the needle during ...

INTRODUCTION Percutaneous renal surgery has been considered one of the most important advances in urology. There are several possibilities to perform a kidney puncture such as using fluoroscopy, ultrasound or both. The aim of this article is to describe our puncture technique. MATERIAL AND METHODS Correct puncture is one of the most critical and challenging steps during percutaneous surgery. ...

The issue of what constitutes an effective and realistic acupuncture placebo control has been a continuing problem for acupuncture research. In order to provide an effective placebo, the control procedure must be convincing, visible and should mimic, in all respects, apart from a physiological effect, the real active treatment. The 'Streitberger' needle might fulfil these criteria and this pape...

AIM To estimate suspect nodule for benign or malignant characteristics, and to verify cytological features of the node with the fine needle aspiration (FNA) under ultrasound. DESIGN A total of 106 patients were analyzed. FNA biopsy was performed at outpatient clinic via ultrasound. Inform consent was signed for each patient. Preparation of procedure with local anaesthesia was made by assistan...

Abstract In this paper, different proportions of graphene modifiers were used to double-modify the SBS-modified asphalt. The needle penetration, softening point, and ductility modified asphalt with incorporation measured by national standard test method. As affected adding on three indexes SBS was studied. Through analysis comparison experimental results, when parameter is 0.5%, performance gra...

Hollow needles of micron dimensions have previously been fabricated and envisioned for use with transdermal patches or infusion pumps to achieve painless delivery of drugs to the skin for local and systemic effects without the need for hypodermic needles. However, little work has been carried out to identify methods to effectively use hollow microneedles for drug delivery. To address this need,...

One limitation of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the size of the available needles, frequently yielding only cells for cytological examination. The aim of this pilot study was to evaluate the efficacy and safety of newly developed needle forceps to obtain tissue for the histological diagnosis of enlarged mediastinal lymph nodes. Patients with enl...
