یکی از کاربردهای مهم موتورهای دیزلی در مصارف حساس نظامی و صنعتی، استفاده به عنوان منابع تولید برق ایستگاهی می باشد. تنظیم دقیق دور این موتورها در جهت تثبیت فرکانس ژنراتور متصل به آن در زمان های ایجاد تغییرات در بار متصل (نظیر رادارهای نظامی) از اهمیت بالایی برخوردار است. در اکثر موارد از روش های مکانیکی در جهت تثبیت دور این موتورها استفاده می شود که این روش از دقت بالایی برخوردار نمی باشد. در ا...
Acetyl-L-carnitine (ALC) and propionyl-L-carnitine (PLC) are two naturally occurring carnitine derivates formed by carnitine acetyltransferase. The beneficial cardiovascular effects of ALC and PLC have been extensively evaluated in animals and humans during the last 20 years. For instance, many clinical trials have suggested ALC and PLC as potential strategies in the management of peripheral ar...
The TrkB receptor tyrosine kinase and its ligand, BDNF, have an essential role in certain forms of synaptic plasticity. However, the downstream pathways required to mediate these functions are unknown. We have studied mice with a targeted mutation in either the Shc or the phospholipase Cgamma (PLCgamma) docking sites of TrkB (trkB(SHC/SHC) and trkB(PLC/PLC) mice). We found that hippocampal long...
Power line channel is the time-frequency variant channel with impulsive noise. Therefore, power line communication makes performance degradation due to time-frequency variant and impulsive noise. To overcome performance degradation, we consider the unitary signal constellation scheme and investigate the performance improvement of unitary matrix frequency modulated orthogonal frequencydivision m...
This paper deals with power line communication in vehicle (PLC). PLC is a very promising communication solution in order to offer future in-vehicle applications without increasing wiring harnesses. We join recent additional measurements which have been carried out using modified indoor PLC modems. These PLC modems are based on the two main technologies, HomePLUG AV and HDPLC. Index Terms HomePL...
A new Multiple-Input Single-Output Powerline Communications (MISO PLC) transmission scheme is proposed as an extension to the conventional Single-Input Single-Output (SISO) PLC transmission scheme to achieve high data rate with diversity. This scheme is called Enhanced-PLC scheme (EPLC). A Space-Time (ST) coding is employed at the transmitter terminal. In addition, a modified Maximum-Likelihood...
Isolated posterolateral corner (PLC) injuries are rarely seen with tibial plateau fractures and can be missed during the initial assessment. The objective of this paper is to present a case of a Schatzker type 2 tibial plateau fracture with associated isolated PLC injury and give a discussion on physical exam, diagnostic studies, and treatment options. A twenty-five-year-old female sustained a ...
Two signaling pathways known to be essential for progression from immature to mature B cells are BAFF receptor (BAFF-R) and the B cell receptor (BCR). Here, we first show that phospholipase C (PLC)-gamma2 is required for a BAFF-R-mediated survival signal. Then, we have examined the question of whether the reduced number of mature B cells in PLC-gamma2-/- mice is caused by a defect in either BCR...
BACKGROUND The prognostic impact of serum carcinoembryonic antigen (CEA) levels and pleural lavage cytology (PLC) in female patients with non-small cell lung cancer (NSCLC) were examined. METHODS A consecutive series of 122 women with NSCLC who underwent surgical resection and PLC were included in the study. RESULTS The 5-year survival rate of patients with preoperative serum normal and ele...
Introduction: Introduction: Molecular components within the microenvironment act upon cell growth, survival/apoptosis, and proliferation. Immune system cells respond to molecules produced by the tumor and released in the surrounding microenvironment, such as cytokines, chemokines, and growth factors. This study aimed to identify the effects of tumor environment on monocyte-macrophage cell linea...
