Systematic review, including meta-analysis, is increasingly utilized in life cycle assessment (LCA). There are currently no widely recognized guidelines for designing, conducting, or reporting systematic reviews in LCA. Other disciplines such as medicine, ecology, and software engineering have both recognized the utility of systematic reviews and created standardized protocols for conducting an...
شرکت های نرم افزاری به صورت تخصصی تر در حوزه های گوناگون (مثلاً برخی از شرکت ها به طراحی، تحلیل، جمع آوری نیازمندی ها، تست نرم افزار و ...) به تولید و توسعه محصولات نرم افزاری می پردازند و همچنین توسعه نرم افزارهای برون سپاری و نرم افزارهای جهانی مطرح می شود که مستلزم استفاده از روش ها و استانداردها برای کنترل و مدیریت بین فرایندها تولید و توسعه نرم افزار می باشد. عدم یکپارچگی بین فرایندهای مهند...
This work studies lowest common ancestor problems in directed acyclic graphs. We present fast algorithms for solving the All-Pairs Representative LCA and AllPairs All LCA problems with expected running time of O(n2 log n) and O(n3 log log n) respectively. The speed-ups over recently developed methods are achieved by applying transitive reduction on the input dags. The algorithms are experimenta...
Life-Cycle Assessment (LCA) analyzes the total energy and resource requirements and environmental impact of human-designed systems. Both policymakers and industry have shown a great deal of interest in applying LCA as a decision-making criterion during planning and design for new pavement construction, and maintenance and rehabilitation activities. This interest results from two different persp...
Licochalcone A (LCA), a licorice chalconoid, is considered to be a bioactive agent with chemopreventive potential. This study investigated the mechanisms involved in LCA-induced apoptosis in human bladder cancer T24 cells. LCA significantly inhibited cells proliferation, increased reactive oxygen species (ROS) levels, and caused T24 cells apoptosis. Moreover, LCA induced mitochondrial dysfuncti...
Commentary | Dermatol Pract Concept 2013;4(1):5 43 Have we really concluded what a large cell acanthoma is? Is it a distinct entity, a solar lentigo, a subtype of seborrheic keratosis, or an HPV-induced acanthoma? In 1970, large cell acanthoma (LCA) was first described by Pinkus, as a sharply demarcated, hyperkeratotic patch, often on sun-exposed skin, characterized by extraordinarily large cel...
PURPOSE Leber congenital amaurosis (LCA) and juvenile retinitis pigmentosa (RP) cause severe visual impairment early in life. Thus far, mutations in 13 genes have been associated with autosomal recessive LCA and juvenile RP. The purpose of this study was to use homozygosity mapping to identify mutations in known LCA and juvenile RP genes. METHODS The genomes of 93 consanguineous and nonconsan...
BACKGROUND AND AIMS Root cortical aerenchyma (RCA) increases water and nutrient acquisition by reducing the metabolic costs of soil exploration. In this study the hypothesis was tested that living cortical area (LCA; transversal root cortical area minus aerenchyma area and intercellular air space) is a better predictor of root respiration, soil exploration and, therefore, drought tolerance than...
Licochalcone A (LCA) is a flavonoid extracted from licorice root that has antiparasitic, antibacterial and antitumor properties. Previous studies have revealed that LCA may be a novel treatment for gastric cancer. The present study further assessed the potential antitumor effects of LCA alone or in combination with 5-fluorouracil (5-FU), and the underlying mechanisms responsible for those effec...
The family of leucocyte common antigen (LCA) transmembrane glycoproteins is expressed in most hematopoietic cells. Molecular isoforms of the LCA molecule are generated by alternative splicing of a single gene encoded on the murine chromosome 1. Three LCA alleles with different antigenic reactivities have been identified in inbred mouse strains. To investigate the divergence between alleles, cDN...
