this study examined the accuracy between extension professionals and farmers regarding their perceptions of privatization and commercialization of agricultural extension services. the study was carried out in delta state, nigeria and it had a sample size of 224 respondents comprising of 134 extension professionals of the delta state agricultural programme (dtadp) and 90 farmers that were random...

The effects of dietary antioxidant supplementation on oxidative stress and life span are confused. We maintained C57BL/6 mice at 7 2°C and supplemented their diet with -tocopherol from 4 months of age. Supplementation significantly increased (p 0.042) median life span by 15% (785 days, n 44) relative to unsupplemented controls (682 days, n 43) and also increased maximum life span (oldest 10%, p...

The effects of dietary antioxidant supplementation on oxidative stress and life span are confused. We maintained C57BL/6 mice at 7 +/- 2 degrees C and supplemented their diet with alpha-tocopherol from 4 months of age. Supplementation significantly increased (p = 0.042) median life span by 15% (785 days, n = 44) relative to unsupplemented controls (682 days, n = 43) and also increased maximum l...

This study computes the eco-efficiency of High Yielding Variety (HYV) rice production by including an on-farm environmental damage index (OFEDI) as an undesirable output using Data Envelopment Analysis (DEA) and then identifies its determinants by applying an interval regression procedure on a sample of 317 farmers from north-western Bangladesh. Results reveal that the mean level of the OFEDI-a...

We recently developed a method to measure cortical bone fracture initiation toughness using a double-notched beam in four-point bending. This method was used to test the hypothesis that mineralization around the two notch roots is correlated with fracture toughness and crack extension (physical damage). Total energy absorbed to failure negatively correlated with average mineralization of the be...

The extension of germ tubes into elongated hyphae by Candida albicans is essential for damage of host cells. The C. albicans-specific gene EED1 plays a crucial role in this extension and maintenance of filamentous growth. eed1Δ cells failed to extend germ tubes into long filaments and switched back to yeast growth after 3 h of incubation during growth on plastic surfaces. Expression of EED1 is ...

DNA is susceptible to alkylation damage by a number of environmental agents that modify the Watson-Crick edge of the bases. Such lesions, if not repaired, may be bypassed by Y-family DNA polymerases. The bypass polymerase Dpo4 is strongly inhibited by 1-methylguanine (m1G) and 3-methylcytosine (m3C), with nucleotide incorporation opposite these lesions being predominantly mutagenic. Further, ex...

Background. The goal of our research was to evaluate the effectiveness of rehabilitation in cases of major damage to the anterior cruciate ligament. Material and methods. The research involved a group of 80 persons in rehabilitation who had previously been active in sports, and had incurred damage to the anterior cruciate ligament. The examinations covered the circumference of the knee and hip,...

The amount and variety of composite structures that need to be inspected for the presence of impact damage has grown significantly in the last few decades. In this paper, an application of a probabilistic ultrasonic guided wave imaging technique for impact damage detection in carbon fiber-reinforced polymers (CFRP) is presented. On the one hand, a linear, baseline-dependent, technique utilizing...
