Gentlemen and My Dear Brothers...

In this 1962 circular, Superior General William Slattery discusses the evangelical maxims. Every aspect of our conduct should follow the example of Jesus’s life and teachings. To do this, we must think like Jesus, sacrifice like him, and make the salvation of our souls our primary objective. If this ever seems easy, we either have a poor understanding of what Jesus asks, or we lighten his message so it does not contrast so much with the lives of unbelievers. Since our weakness and the pressure of the world around us can lead us astray, we require grace to maintain and practice our faith

Gentlemen and My Dear Brothers...II

In this excerpt of a 1968 circular, Superior General William Slattery explores the Second Vatican Council’s principles for renewal of the Church in general and in community life. By following Christ in every aspect of our lives, we inspire others to do so, causing renewal of Christian life in the world. The Congregation’s charism particularly obliges us to undertake works that respond to the modern needs of the Church and the world. We must also focus on personal spiritual renewal, on which all other renewal depends

Wage payment and incentive plans used by department and departmentalized specialty stores in six North Carolina cities

The compensation of salespeople by methods which are fair to the employee and satisfactory to the store itself is one of the major problems of retailing. An inspection of the programs of the annual conventions of the National Retail Dry Goods Association for the last five years shows that the problem of finding satisfactory plans for compensating salespeople is still unsolved. At each of these national conventions the subject of wage payment and incentive plans for salespeople has come up for major discussions. As late as May 1950, the Store Management and Personnel Groups of this association gave a very prominent place to a panel discussion of "The Perfect Payment Plan for Salespeople” during the midyear convention of these groups held in Detroit, Michigan. A recent letter from the Assistant Manager of the Personnel Group of the National Retail Dry Goods Association bears out the fact that the Association still considers the problems of wage payment plans in the field of retailing as one of major importance. The following is a quotation from this letter.

Applications of a Hybrid Manufacturing Process for Fabrication and Repair of Metallic Structures

Since its appearance, rapid prototyping technology has been of interest to various industries that are looking for a process to produce/build a part directly from a CAD model in a short time. Among them, the direct metal deposition process is the only process which directly manufactures a fully dense metal part without intermediate steps. However, challenges of the direct metal deposition process include building overhang structures, producing precision surfaces, and making parts with complex structures. Coupled between the additive and the subtractive processes into a single workstation, the integrated process, or hybrid process, can produce a metal part with machining accuracy and surface finish. Therefore, the hybrid process is potentially a very competitive process to fabricate and repair metallic structures. This paper summarizes the current development of the hybrid process to process high temperature metallic materials, including tool steel and Ti64. Research in simulation and modeling, process development, and actual part building and repair are discussed

Modeling and Simulation of a Laser Deposition Process

A laser deposition process involves the supply of metallic powders into a laser-heated spot where the powder is melted and forms a melt puddle which quickly solidifies into a bead. In order to design an effective system, the laser beam, the powder beam, and their interactions need to be fully understood. In this paper, the laser-material interaction within the melt pool is reported using a multi-scale model: A macroscopic model to model mass, heat, and momentum transfer. Experiments were also conducted to validate the simulation model

Growth of Lion and Puma Lentiviruses in Domestic Cat Cells and Comparisons with FIV

AbstractFeline immunodeficiency virus (FIV-Fca) is a lentivirus that causes gradual immunological deterioration in domestic cats. Lentiviruses related to FIV have been detected in several nondomestic feline species; the biologic significance of these viruses remains to be defined. To examine thein vitrocell tropism of these nondomestic cat lentiviruses, prototypical puma and lion lentiviruses (FIV-Pco and FIV-Ple) were cultured in a variety of feline cell cultures. A domestic cat T lymphoma cell line, 3201, best supported the replication of both FIV-Pco and FIV-Ple. Moreover, FIV-Ple was lytic for these cells. RT-PCR amplification of a conservedpolgene region demonstrated species-specific primer homology. Sequence and phylogenetic analyses of this amplification product confirmed the identity of the replicating viruses and classified two previously uncharacterized viruses within predictable lion and puma clades. Sequence analysis of a conservedpolregion demonstrated homology with previously characterized FIV-Ple and FIV-Pco. Western blot analysis using domestic cat anti-FIV-Fca sera showed that both FIV-Pco and FIV-Ple were antigenically related, to differing degrees, to three serotypes of FIV-Fca. These studies demonstrate that though nondomestic cat lentiviruses differ significantly from FIV-Fca and that a viral-specific protocol may be necessary for sensitive viral detection, these viruses can replicate in cells of domestic cats, suggesting the potential for cross-species transmission

Driven dynamics and rotary echo of a qubit tunably coupled to a harmonic oscillator

We have investigated the driven dynamics of a superconducting flux qubit that is tunably coupled to a microwave resonator. We find that the qubit experiences an oscillating field mediated by off-resonant driving of the resonator, leading to strong modifications of the qubit Rabi frequency. This opens an additional noise channel, and we find that low-frequency noise in the coupling parameter causes a reduction of the coherence time during driven evolution. The noise can be mitigated with the rotary-echo pulse sequence, which, for driven systems, is analogous to the Hahn-echo sequence

Telescoped approach to aryl hydroxymethylation in the synthesis of a key pharmaceutical intermediate

An efficient synthetic approach leading to introduction of the hydroxymethyl group to an aryl moiety via combination of the Bouveault formylation and hydride reduction has been optimized using a rational, mechanistic-based approach. This approach enabled telescoping of the two steps into a single efficient process, readily amenable to scaleup

Reproductive Aging Influences Ovarian Function in Beef Cows

Anti-Müllerian Hormone (AMH) has been associated with follicle number and age of the ovary. Therefore, our hypothesiswas that AMH was a biomarker for both follicle number and ovarian function in the beef cow. Ovaries were collected by flank laparotomy. The number of follicles increased as cows aged from 1.5 to 6 years and began to decrease thereafter; however, the size of the ovary continued to increase with advanced age. Expression of the AMH gene increased with increasing follicle number in 2-year-old beef cows. These results suggest that heifers with larger ovaries will have greater numbers of follicles and greater productivity, allowing them to stay in the production herd longer. AMH could be used to identify heifers of high reproductive potential at a very young age
