Exposure-Tolerant Imaging Solution forCultural Heritage Monitoring
No full textThis paper describes a simple and cheap solution specifically designed for monitoring the degradation of thin coatings employed for metal protection. The proposed solution employs a commercial photocamera and a frequency-domain-based approach that is capable of highlighting the surface uniformity changes due to initial corrosion. Even though the proposed solution is specifically designed to monitor the long-time performance of protective coatings employed for the restoration of silver artifacts, it can be successfully used also for assessing the conservation state of other ancient metallic works of art. The proposed solution is made tolerant to exposure changes by using a procedure for sensor nonlinearity identification and correction, does not require a precise lighting control, and employs only free open-source software, so that its overall cost is very low and can be used also by not specifically trained operator
The C-Section Epidemic: What's Tort Reform Got to Do With It?
No full textToday one in three babies in the United States comes into the world by cesarean section. The cesarean section has become the most commonly performed operating room procedure in the United States. Conventional wisdom holds that malpractice liability bears primary responsibility for the cesarean section epidemic and that tort reform, which caps physician liability, holds the key to its reduction. This article presents new aggregate empirical data that debunks this view. For the first time, it provides a national cesarean rate for births subject to damage caps and a national cesarean rate for births without damage caps. This data shows that a woman is not less likely to give birth by cesarean section in a state with damage caps than in one without. Thus, either damage caps are insufficient to address physicians’ concerns or other explanations better account for the overuse of the procedure. The empirical analysis will assist policy makers and advocates seeking to reduce the cesarean rate as well as contribute to consideration of the efficacy of medical malpractice reform as a means to reduce the broader problem of medical overtreatment.
The article then outlines three policy initiatives to reduce the cesarean section rate. First, it suggests upending the current payment practice for deliveries. Contrary to the present norm, it proposes that obstetricians receive more rather than less to deliver vaginally to compensate them for the extra time that vaginal delivery takes compared to cesarean delivery. Second, rather than looking to tort reform to reduce cesarean section rates, the article explores whether malpractice insurance providers themselves are contributing to the cesarean section epidemic and advocates two novel medical malpractice insurance reforms to address this problem. Third, it advocates public disclosure of hospital and physician cesarean section rates so that women can make informed decisions when selecting their health care providers and when determining whether to have a cesarean section
The Pediatric Emergency Care Applied Research Network intermediate-risk predictors were not associated with scanning decisions for minor head injuries
No full textAim: This study determined the predictors associated with the decision to perform a computed tomography (CT) scan in children with a minor head injury (MHI). We focused on those facing an intermediate risk of clinically important traumatic brain injury (ciTBI), according to the Pediatric Emergency Care Applied Research Network (PECARN) prediction rule.
Methods: A 1-year, cross-sectional study was performed in an Italian paediatric emergency department, focusing on children presenting within 24 h of an MHI and meeting the PECARN intermediate-risk criteria.
Results: We included 308 children, and 47% were younger than 2 years of age. CT scans were carried out on 13%, 1.3% had a ciTBI and one was initially missed but did not need neurosurgery following diagnosis. Single and multiple PECARN intermediate-risk predictors were not associated with whether a CT scan was carried out. The only clinical variable associated with the decision to perform a CT scan was if the child was <3 months of age (OR 18.1, 95% CI, 4.91-66.61).
Conclusion: The PECARN intermediate-risk predictors did not play a major role in the decision to perform a CT scan. The only factor significantly associated with the decision to perform a CT scan was when the patient was younger than 3 months of age

Feminisme Dalam Novel Asya Story Karya Sabrina Febrianti
No full textThe novel Asya Story by Sabrina Febrianti contains the life story of a woman named Asya. In this novel also discusses how Asya's obstinacy and strength in overcoming every problem in his face. The problems described in this study are (1) Are feminism questions about aspects of the wisdom of the female characters in the novel "Asya Story" by Sabrina Febrianti?, (2), (3) Women's questions in the "Asya Story" novel by Sabrina Febrianti? The purpose of this study is to analyze data about the aspects of feminism psychology that discusses the character of female characters, the pressure of feelings of female characters, and the taste of female characters. The theory used by the author to analyze this research is the theory of Sikana (2005), Lubis (2016). The agreement used is a qualitative agreement. The type of research used is library research. The method used is descriptive method. The technique used is the hermeneutic technique. Data analysis using content analysis techniques. The results of the research submitted about the facts of feminism, especially about the policy aspects that often appear in the novel Asya Story by Sabrina Febrianti is a challenge of the character (character) women and recovery figures, women women Figure in the same story with humans in everyday life who always have different thoughts. Human life is often tested with tests and trials, as is the character who discusses the author in a novel. Exams and experiments that will shape the pressure and stress in humans
Handheld-Impedance-Measurement System with seven-decade capability and potentiostatic function
No full textThis paper describes design and test of a new impedance-measurement system for nonlinear devices that exhibits a seven-decade range and works down to a frequency of 0.01 Hz. The system is specifically designed for electrochemical measurements, but the proposed architecture can be employed in many other fields where flexible signal generation and analysis are required. The system employs an unconventional signal generator based on two pulsewidth modulation (PWM) oscillators and an autocalibration system that allows uncertainties of less than 3% to be obtained over a range of 1 kΩ to 100 GΩ. A synchronous demodulation processing allows the noise superimposed to the low-amplitude input signals to be made negligibl
Solving Problems through Katasterismos: Classical Reception in New Zealand author Sabrina Malcolm’s Zeustian Logic
No full textNew Zealand writer Sabrina Malcolm’s 2017 novel Zeustian Logic is a contemporary school story about a family struggling to deal with grief. This text follows in a decades-long tradition of New Zealand YA literature employing Classical reception. The novel illustrates how Classical myth helps a contemporary New Zealand teenager (Tuttle) come to terms with his father’s death and his own feelings of helplessness, frustration and anger. This chapter examines the role of Classical reception in this novel, discussing how the author uses star mythology to underpin the depiction of the protagonist’s coming-of-age. More than that, Malcolm compares Tuttle’s feelings with ancient perceptions of anger and grief and skillfully casts Tuttle, in his quest for knowledge, as a modern-day Telemachus. The chapter concludes with a look at how Tuttle’s attitudes towards Zeus change, as he matures
Heterogeneous distribution of histone methylation in mature human sperm
No full textPurpose
To analyze the presence of various histone modifications in ejaculated human spermatozoa
Methods
In this prospective study, seminal ejaculates from 39 normozoospermic individuals were evaluated for semen analysis and the presence of histone modifications in isolated nuclei.
Results
We observed heterogeneous presence of histone methylation in normal mature human sperm. We observed that 12 to 30 % of the nuclei of normal sperm contain a heterogeneous distribution of the marks H3K4Me1, H3K9Me2, H3K4Me3, H3K79Me2, and H3K36Me3. Moreover, the presence of these marks is higher in the poor motile fraction of the ejaculate, which is associated with poor morphology and functional quality. In contrast, we did not observe histone acetylation (H3K4Ac and H4K5Ac) in normal or abnormal mature human sperm
Conclusions
Defects in the process of spermatogenesis may alter the correct epigenetic programing in mature sperm. Further studies are required to evaluate the impact of these findings in human infertilityFil: la Spina, Florenza Antonella. Consejo Nacional de Investigaciones Científicas y Técnicas.
