Research Notes : The monogenic and digenic control of hypocotyl and flower color in soybeans

The pigmentation of seedling hypocotyl is important in the knowledge, at a very early stage, of success in the cross of plants differing in this aspect. Several genes, among which are W1, W2, W3, W4 and wm, have been recognized as controlling flower pigmentation, and many studies indicate that flower and hypocotyl colors are closely associated. Hartwig and Hinson (1962) put in evidence that hypocotyl of W1W3W4 genotypes is darker than that of W1w3W4 ones

Research Notes : Italy : Light shock in soybean plantlets?

In a new soybean breeding program, 70 cross combinations were performed between the following varieties: \u27Agripro\u27, \u27Beeson\u27, \u27Caloria\u27, \u27Corsoy\u27, \u27Extra Early\u27, \u27Mikawashima\u27, \u27Norman\u27, \u27SRF150\u27, \u27SRF307 P\u27, \u27TXK505\u27, \u27TXK.535\u27, \u27Vansoy\u27, and \u27Wells\u27. Mother plants were the varieties indicated in Table l; in this table is also reported the number of combinations involv-ing each variety used as female and the number of seeds obtained

Sonographic evaluation of subacromial space

Goal of the study. The purpose of this study is to compare the accuracy of sonographic to radiographic measurements of subacromial space, and verify its variations in relation to acromial morphology, age, sex and rotator cuff pathologies. Materials and methods. As a result, we have compared a radiographic examination to sonographic examination, each measuring the subacromial space in 200 random shoulders, with a personal method. The sonographic examination was performed by using a HDI 5000 ultrasound scanner Sono-CT with 7.5 MHz linear array transducer. No stand-off pad was utilized. Results. The statistical analysis of the data derived from the two measurements was not sufficient to conclude that the two techniques are different (p>0.8). They also correspond with the radiographic morphology of the acromion. The size of subacromial space was related to the acromial morphology, female gender, and rotator cuff pathology, however, it was not related to age. Discussion and conclusions. Our results clearly show that sonographic measurements are very close to those obtained by X-ray (p>0.8). The Bland\u2013Altman analysis showed that for all groups, the were small enough to give us confidence that the sonographic technique may be used in place of the radiographic one for clinical purposes. One-way ANOVA showed that sonographic measurements were statistically different among the four groups (p<0.05). The sonography demonstrated precision, accuracy and carefulness in the measurement of the subacromial space

Micro-beam and pulsed laser beam techniques for the micro-fabrication of diamond surface and bulk structures

Micro-fabrication in diamond is involved in a wide set of emerging technologies, exploiting the exceptional characteristics of diamond for application in bio-physics, photonics, radiation detection. Micro ion-beam irradiation and pulsed laser irradiation are complementary techniques, which permit the implementation of complex geometries, by modification and functionalization of surface and/or bulk material, modifying the optical, electrical and mechanical characteristics of the material. In this article we summarize the work done in Florence (Italy) concerning ion beam and pulsed laser beam micro-fabrication in diamond.Comment: 14 pages, 5 figure
