A study for the influence of semen extenders IMV-buffer, HIA- 1 and AU on sperm motion characteristics of Muscovy drake spermatozoa was carried out. The semen from each male (n=6) was divided into three equal parts and diluted in ratio 1:3 (semen:extender) with the IMV-buffer, HIA-1 and AU respectively, and then was stored at temperature 0-4C? for 6 hours. Sperm motion parameters - velocity of spermatozoa (rapid, medium, slow and statistic), VCL, VSL, VAP, LIN, STR, WOB were measured using a Sperm Class Analizer (Micropticum, Spain). Computer-assisted sperm motion analysis indicated that Muscovy spermatozoa preserved a rapid and medium sperm velocity after 6 hours in vitro storage in three examination extenders. The total VCL, VSL and VAP of spermatozoa in the semen diluted with AU extender were 110.47?7.44 ?m/s, 29.42?2.02 ?m/s and 57.39?3.73 ?m/s, in the semen diluted with IMV-buffer were 94.93?11.10 ?m/s, 27.57?2.45 ?m/s and 51.35?4.98 ?m/s, and in the semen diluted with HIA-1 were 68.48?12.74 ?m/s, 20.08?4.18 ?m/s and 37.75?7.65 ?m/s, as the differences were significant between AU and HIA-1 - (P<0.05). About LIN, STR, WOB there were no significant differences for the influence of the extenders.

Abstract. Background: Identifying precursors that will aid in the discovery of individuals who may harm themselves or others has long been a focus of scholarly research. Aim: This work set out to determine if it is possible to use the legacy tokens of active shooters and notes left from individuals who completed suicide to uncover signals that foreshadow their behavior. Method: A total of 25 suicide notes and 21 legacy tokens were compared with a sample of over 20,000 student writings for a preliminary computer-assisted text analysis to determine what differences can be coded with existing computer software to better identify students who may commit self-harm or harm to others. Results: The results support that text analysis techniques with the Linguistic Inquiry and Word Count (LIWC) tool are effective for identifying suicidal or homicidal writings as distinct from each other and from a variety of student writings in an automated fashion. Conclusion: Findings indicate support for automated identification of writings that were associated with harm to self, harm to others, and various other student writing products. This work begins to uncover the viability or larger scale, low cost methods of automatic detection for individuals suffering from harmful ideation.

Abstract Total Knee Arthroplasty is one of the most commonly performed orthopedic procedures and it is expected to grow in the next future. In the last past years, computer-assisted procedures represent one of the trends that are transforming the way of practicing medicine. Cornering the Total Knee Arthroplasty, digital models of the joints have been used to carry out simulation of their kinematics and mechanical performance. Whilst for the 3D digital reconstruction of the patient geometry several studies have been conducted, an approximated geometry of the prosthesis has been several times employed, with undeniable consequences on the final results. This paper aims at comparing two non-contact reverse engineering technologies to acquire the shape of femoral components employed for total knee arthroplasty. A high-level device (Konika Minolta Vivid 9i) and a mid-low cost laser (NextEngine) has been compared. For the comparison, a systematic procedure of acquisition and elaboration of the results has been adopted in order to have as unbiased as possible results. The procedure involves the use of the proprietary software of the scanners for the elaboration of the raw data and the meshing procedure has been kept the same for all the models. Since the as-is acquired mesh is of high-resolution, a decimation procedure has been carried out in order to make the 3D models lighter and easier to be handled. Once the decimation procedure has been evaluated comparing the original and the simplified models to one another, the digitalized models have been compared with the measurements taken from a coordinate measuring machines. As a preliminary result, the two lasers seem to be adequate to accomplish the reverse engineering process as required by this application. Of course, the mid-low cost laser would be preferable whether the performance will be confirmed to be (statistically) equal.
