Amygdalin content in the seeds of several apricot cultivars

Eight different cultivars of apricots (Prunus armeniaca L) have been studied regarding the amygdalin content of their seeds to correlate amygdalin content with known phenotypes to determine if the inheritance of this trait is controlled in a discrete or quantitative manner. HPLC determination of amygdalin showed large differences between cultivars with sweet and bitter kernels. Also, some significant differences within groups of bitter and sweet kerneled cultivars were found but they did not correlate with the phenotypical expression of kernel flavour. From the results it is concluded that bitterness seems to be controlled in a discrete manner and that organoleptic evaluation that classifies cultivars or seedlings as bitter or sweet would be enough with no need for chemical analysis. © 1998 SCI.

Intergenerational dynamics of digital transformation in family firms

The integration of digital technologies and processes presents a multifaceted and complex challenge for family firms, as they must navigate new technologies while maintaining their unique familial attribute. Moreover, the issue of intergenerational inheritance adds an additional layer of complexity, as succession must be effectively executed to ensure the continued success and survival of the family firm in the digital age. Together, these challenges pose a significant threat to the sustainability and competitiveness of family firms. To gain a deeper understanding of how these challenges can be effectively addressed, the study utilizes data from the 2016 Chinese Private Enterprises Survey to identify the factors influencing family firms' digital transformation and the role of entrepreneurs' characteristics in this process. From the perspective of intergenerational inheritance, the study finds that both the willingness of entrepreneurs to hand over power and the willingness of their children to take over firm power have a moderating effect on the relationships between entrepreneurs' characteristics and firms’ digital transformations. This study also verifies the heterogeneous effects from the type of business digitalization, location of the firm, and educational level of the children.

TB9钛合金棒材组织遗传效应与性能

以TB9钛合金为研究对象，对比分析了TB9铸锭不同部位在热加工过程中的组织差异，揭示了TB9钛合金棒材的组织遗传效应及其对性能的影响。结果表明，TB9钛合金铸锭可以分为底部沿轴向的柱状晶区，芯部的等轴晶区，边部与轴向呈45°的柱状晶区。其中铸锭底部的柱状晶具有较强的<100>织构，在随后的锻造和热轧过程中，<100>织构的柱状晶难以破碎，具有很强的遗传性，致使最终棒材尾部残留粗大的柱状晶结构，时效后抗拉强度仅为987 MPa。铸锭芯部等轴晶区没有明显的择优取向，最终制备的棒材晶粒细小，组织均匀，棒材的性能优良，抗拉强度可达1290 MPa。
