Effect of feeding on linseed oil (LO)-enriched Artemia was investigated on growth, survival and stress resistance of tiger barb (Puntius tetrazona) larvae. Larvae were fed by LO-enriched (2.5, 5 and 7.5 %) as well as non-enriched Artemia nauplii for 14 d, followed by 14 d feeding on non-enriched Artemia. Fish fed on enriched nauplii showed significant increase in growth performance at both 14th...

n a paradox experienced by many IT managers, organizational information systems (OISs) are implemented and function exactly as designed—a success by all objective measures—yet users are still disappointed and consider them unsuccessful. Exploring this paradox here, we recommend ways to reduce the root causes of such disappointment. Researchers and practitioners alike have long focused on the su...

for sharing information has brought with it the corresponding ubiquity of URL references and citations. URLs regularly appear on billboards, packages, business cards, print advertisements, clothing, and as references in scientific articles. Most readers have probably experienced a “dead link”: a Web reference that for a variety of reasons will not lead to a valid or correct Web page. A dead lin...

Face recognition is important in human identification. The biological recognition technique acts as a good method and broad applications in security areas. This work presents a method to improve the face recognition accuracy using a combination of Principal Component Analysis (PCA), and Wavelet Transform. Wavelet Transform is used to decompose the input image with different levels and rearrange...

Wearable technology is increasingly used to identify episodes of atrial fibrillation (AF). However, most validation studies using single-lead ECGs only included patients with either sinus rhythm or AF and, therefore, likely overestimate the sensitivity and specificity detection algorithms. We sought compare diagnostic accuracy Apple Watch (APW) series 6 CART-I ring (C-ring) algorithms physician...

صخلملا Infertility affects 15% of couples seeking children worldwide and male factor is evident in about 30-50% of the cases. To assess the effect of sperm chromatin integrity on the outcomes of intracytoplasmic injection, sperm DNA compactness was evaluated by acridine orange staining in 40 fertile and 44 infertile men attending one infertility clinic. The results showed no significant differe...
