IC.IDO as a tool for displaying machining processes. The logic interface between computer-aided-manufacturing and virtual reality

This scientific communication investigates the logic interface of a CAM solver, i.e., MasterCAM, into a Virtual Reality (VR) environment. This integration helps in displaying machining operations in virtual reality. Currently, to partially visualize the results of a simulation in an immersive environment, an import/export procedure must be done manually. Here, a software plugin integrated into IC.IDO (by ESI Group) has been realized and fully described. This application allows the complete integration of CAM solver into the VR environment. In particular, the VERICUT solver has been integrated into VR. This kind of integration has never been done yet

The Development of the Teacher as a Professional in an Alternative Teacher Education Program

Recruitment and retention strategies are a growing concern for Catholic educational leaders. This article offers a glimpse into the dynamics of a leading teacher recruitment effort, the Alliance for Catholic Education (ACE) sponsored by the University of Notre Dame. After surveying the first two cohorts who taught in Catholic schools through ACE, the authors uncover significant and meaningful components of this alternative teacher preparation program with a view to challenging traditional teacher education efforts and preservice requirements

Dynamics of the magnetic and structural a -> e phase transition in Iron

We have studied the high-pressure iron bcc to hcp phase transition by simultaneous X-ray Magnetic Circular Dichroism (XMCD) and X-ray Absorption Spectroscopy (XAS) with an X-ray dispersive spectrometer. The combination of the two techniques allows us to obtain simultaneously information on both the structure and the magnetic state of Iron under pressure. The magnetic and structural transitions simultaneously observed are sharp. Both are of first order in agreement with theoretical prediction. The pressure domain of the transition observed (2.4 $\pm$ 0.2 GPa) is narrower than that usually cited in the literature (8 GPa). Our data indicate that the magnetic transition slightly precedes the structural one, suggesting that the origin of the instability of the bcc phase in iron with increasing pressure is to be attributed to the effect of pressure on magnetism as predicted by spin-polarized full potential total energy calculations

A Cloud Telemedicine Platform Based on Workflow Management System: A Review of an Italian Case Study

The paper aims to describe a new technological and organizational approach in order to manage teleconsultation and telemonitoring processes involving a Physician, who remotely interacts with one or more Specialists, in order to evaluate and discuss the specific clinical conditions of a patient, based primarily on the sharing of digital clinical data, reports and diagnostic images. In the HINT project (Healthcare INtegration in Telemedicine), a teleconsultation and telemonitoring cloud platform has been developed using a Hub and Spoke architecture, based on a Business Process Management System (BPMS). The specialized clinical centres (Hubs) operate in connection with the territorial hospital centres (Spokes), which receive specific diagnostic consultations and telemonitoring data from the appropriate Specialist, supported by advanced AI systems. The developed platform overcomes the concepts of a traditional and fragmented teleconsultation and consequently the static organization of Hubs and Spokes, evolving towards an integrated clinical workflow management. The project platform adopts international healthcare standards, such as HL7 FHIR, IHE (XDS and XDW) and DICOM for the acquisition and management of healthcare data and diagnostic images. A Workflow Management System implemented in the platform allows to manage multiple and contemporaneous processes through a single platform, correctly associating the tasks to the Physicians responsible for their execution, monitoring the status of the health activities and managing possible clinical issues

Bifidobacterium mellis sp. nov., isolated from the honey stomach of the honey bee Apis mellifera

: A novel Bifidobacterium strain, Bin7NT, was isolated from the honey stomach of the honey bee Apis mellifera. Cells are Gram-positive, non-motile, non-sporulating, facultative anaerobic and fructose 6-phosphate phosphoketolase-positive. Their optimal growth is at 37 °C in anaerobiosis in MRS (De Man, Rogosa and Sharpe) added with cysteine. The honey bee microbiota was composed of several phylotypes of Bifidobacterium and Lactobacillus. Comparative analysis of 16S rRNA gene sequence similarity revealed that strain Bin7NT grouped with Bifidobacterium species originating from honey bees and was closely related to Bifidobacterium asteroides DSM 20089T (99.67 % similarity). However, the highest average nucleotide identity and digital DNA-DNA hybridization values of 94.88 and 60.6 %, respectively, were obtained with Bifidobacterium choladohabitans JCM 34586T. The DNA G+C content of the type strain is 60.8 mol%. The cell-wall peptidoglycan is of the A4β l-Orn-d-Asp type. The main cellular fatty acids of strain Bin7NT are C18 : 1 ω9c, C16 : 0, C18 : 1 ω7c and C18 : 0. Phenotypic characterization and genotyping based on the genome sequences clearly show that this strain is distinct from the type strains of the so far recognized Bifidobacterium species. Thus, Bifidobacterium mellis sp. nov. (Bin7NT=DSM 29108T=CCUG 66113T) is proposed as novel Bifidobacterium species

Interplay of the electronic and lattice degrees of freedom in A_{1-x}Fe_{2-y}Se_{2} superconductors under pressure

The local structure and electronic properties of Rb$_{1-x}$Fe$_{2-y}$Se$_2$ are investigated by means of site selective polarized x-ray absorption spectroscopy at the iron and selenium K-edges as a function of pressure. A combination of dispersive geometry and novel nanodiamond anvil pressure-cell has permitted to reveal a step-like decrease in the Fe-Se bond distance at $p\simeq11$ GPa. The position of the Fe K-edge pre-peak, which is directly related to the position of the chemical potential, remains nearly constant until $\sim6$ GPa, followed by an increase until $p\simeq 11$ GPa. Here, as in the local structure, a step-like decrease of the chemical potential is seen. Thus, the present results provide compelling evidence that the origin of the reemerging superconductivity in $A_{1-x}$Fe$_{2-y}$Se$_2$ in vicinity of a quantum critical transition is caused mainly by the changes in the electronic structure

Experimental exploration of the origin of magnetostriction in single crystalline iron

The magnetostrictive atomic strain in a pure Fe single crystal was measured by differential x-ray absorption spectroscopy. The obtained tetragonal magnetostriction constant, (3/2)λ100, was determined to be 45 ppm, consistent with the previously reported theoretical value calculated from a spin-orbit coupling theory. These results provide a foundation for understanding the origin of magnetostriction in pure Fe as well as Fe-based binary alloys

One-year follow-up of mud-bath therapy in patients with bilateral knee osteoarthritis: a randomized, single-blind controlled trial

The objective of this prospective parallel randomized single-blind study was to assess that a cycle of mud-bath therapy (MBT) provides any benefits over usual treatment in patients with bilateral knee osteoarthritis (OA). Patients with symptomatic primary bilateral knee OA, according to ACR criteria, were included in the study and randomized to one of two groups: one group received a cycle of MBT at spa center of Chianciano Terme (Italy) in addition to the usual treatment, and one group continued their regular care routine alone. Clinical assessments were performed 7\ufffddays before enrollment (screening visit), at the time of enrollment (basal time), after 2\ufffdweeks, and after 3, 6, 9, and 12\ufffdmonths after the beginning of the study. All assessments were conducted by two researchers blinded to treatment allocation. The primary efficacy outcomes were the global pain score evaluated by Visual Analog Scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) subscore for physical function (W-TPFS). Of the 235 patients screened, 103 met the inclusion criteria: 53 patients were included in the MBT group and 50 in the control group. In the group of patients treated with MBT, we observed a statistically significant (p\ufffd<\ufffd0.001) reduction of VAS and W-TPFS score at the end of the treatment; this improvement was significant (p\ufffd<\ufffd0.05) also at 3\ufffdmonths of follow-up. The control group did not show significant differences between baseline time and all other times. The differences between one group were significant for both primary parameters already from the 15th day and persisted up to the 9th month. This beneficial effect was confirmed by the significant reduction of symptomatic drug consumption. Tolerability of MBT seemed to be good, with light and transitory side effects. Our results confirm that a cycle of MBT added to usual treatment provides a beneficial effect on the painful symptoms and functional capacities in patients with knee OA that lasts over time. Mud-bath therapy can represent a useful backup to pharmacologic treatment of knee OA or a valid alternative for patients who do not tolerate pharmacological treatments
