Phenolated lignosulfonate was introduced into the synthesis of phenolic resol with phenol and formaldehyde in an alkaline condition. The modified resol was successfully applied to prepare phenolic foam using appropriate combinations of flowing agents. N-pentane was found to be suitable as the foaming agent. Sulphuric acid (50% aqueous solution, w/w) and Tween-80 were used as catalyst and surfac...

background: angiogenesis, the development of new blood vessels, is an important process in tissue development and wound healing, but becomes pathologic when associated with solid tumor growth, proliferative retinopathies, and rheumatoid arthritis. accurate and reliable qualification of neovascular (angiogenic) response, both in vitro and in vivo, is an essential requirement for the study of new...

OBJECTIVE To further examine the reliability of categorical loudness scaling (CLS) for individual loudness categories and for the slope of the CLS functions. And, to evaluate the relationship between CLS and audiometric threshold. DESIGN CLS functions were obtained in 74 subjects, 58 with hearing loss and 16 with normal hearing. CLS functions were measured at three frequencies (1, 2, and 4 kH...

Automatically discovering cross-lingual links (CLs) between wikis can largely enrich the cross-lingual knowledge and facilitate knowledge sharing across different languages. In most existing approaches for cross-lingual knowledge linking, the seed CLs and the inner link structures are two important factors for finding new CLs. When there are insufficient seed CLs and inner links, discovering ne...

Coffin-Lowry syndrome (CLS) is an X-linked disorder, which affects hemizygous males more severely than females. It is characterized by mental retardation, short stature, head and facial abnormalities, skeletal anomalies and developmental delays. The signs and symptoms vary in different people. We report a 14-year-old male patient, diagnosed with CLS based on his clinical features. Genetic testi...

Purpose To develop a simple extraction procedure to quantify the uptake of four topical ocular pharmaceutical drugs into contact lenses (CLs). Methods Four silicone hydrogel (SH) CLs (balafilcon A, senofilcon A, lotrafilcon B, comfilcon B) and four conventional hydrogel (CH) CLs (nesofilcon A, hilafilcon B, nelfilcon A, etafilcon A) were evaluated. The drugs studied were natamycin, moxifloxac...

The complexity of humic substances and their remarkable properties have attracted and continue to attract the attention of many investigators, bringing over the years new knowledge on their structure, physicochemical and biological properties pointing to the use of these interesting natural compounds in many practical applications. The numerous investigations produced, up to now, controversial ...

The physicochemical characteristics of the meat from lambs fed diets containing whole or disintegrated cottonseed, associated not with calcium lignosulfonate (LignoCaSO3), were evaluated. Thirty non-castrated Dorper x Santa Inês lambs, an average 24.9 ± 3.6 kg and four months age confined for 60 days in collective stalls distributed a completely randomized design six replications. After slaught...

The study of lime-based systems is vital to the design new sustainable building materials. Air lime (calcium hydroxide, Ca (OH) 2 ) a binder that has attracted considerable attention for its ability capture CO from atmosphere, low-cost and low-energy production process. Furthermore, an important phase hydrated Portland cements, mortars have shown high elasticity self-healing. performance materi...

In rats, sexual reward, appetitive sexual behaviors and reproduction are modulated by the amount and rate of vaginocervical stimulation. Here the effect of clitoral stimulation (CLS) on proceptivity was assessed. In Exp 1, ovariectomized, hormone-primed Wistar females formed three groups: G1 (1 CLS every second), G2 (1 CLS every 5s) and G3 (no CLS). Precopulatory CLS consisted of 5cycles of 1mi...
