The possibility of applying combined heat and power microgrid model for industrial parks. A case study for Dong Nam industrial park in Vietnam

2023

Microgrid systems that combine cooling, heating and power (CHP) with distributed cogeneration units and renewable energy sources are a practical way to meet the growing need for energy, and industrial parks have enormous potential for the development of integrated electrical and thermal systems. This paper presents a microgrid CHP model and evaluates the possibility of developing the model in the Dong Nam industrial park in Ho Chi Minh City, Vietnam. HOMER software was used to evaluate the effectiveness of the model.

CONCORDANCE AND DISTRIBUTION OF HPV GENOTYPES IN HPV INFECTED SEXUAL COUPLES

2016

Introductions: The characteristics of HPV infection in women have been extensively investigates, however, only a few studies have analyzed the characteristics of HPV infection in men and in sexual couples. Materials and methods: 195 sexual couples positive for HPV-DNA were examined, at the Virology laboratory of the Department of Sciences for Health Promotion and Mother and Child Care (Policlinico, University of Palermo, Italy). HPV-DNA detection was performed by the INNOLiPA HPV Genotyping Extra II Test (Fujirebio) and nested PCR/sequencing method. All women (range: 20-60, mean age: 31.5 ys) had performed a pap smear and knew the cytological diagnosis: 73 (37.4%) negative at Pap smear, 21 …

Predictive role of histological features and Ki67 pattern on high-risk HPV presence in atypical cervical lesions

2007

The most frequently detected alterations of squamous cervical epithelia consist of metaplastic/reactive conditions and human papillomavirus (HPV)-related dysplastic lesions. These latter are traditionally identified as cervical intraepithelial neoplasia (CIN1, 2 or 3) or, in the Bethesda System, as low-grade squamous intraepithelial lesions (LSIL), including CIN1, and high-grade SIL, including CIN2 and CIN3. Some HPV-induced lesions, which are not characterized by obvious dysplasia, are often diagnosed as LSIL. In these lesions, which are hereafter referred to as cervical atipical lesions (CAL), histological features of HPV infection (namely, koilocytosis, multinucleation, acanthosis, papil…

The effects of HPV infection on semen: first results from a new approach.

2017

Study question: The effect of HPV infection on semen characteristics was investigated using a new method that allow to evaluate virus localization in the different semen components. Summary answer: Our data indicate a correlation between HPV infection of exfoliated epithelial cells (from spermatic ducts and accessory glands) and reduction of sperm cell motility. What is known already: HPVs are agents of the most common sexually transmitted diseases. Both in men and in women, HPVs cause a variety of clinical symptoms ranging from warts to cancer. It has been shown (IARC, 2009) that infection with 12 oncogenic HPVs is the major cause of development of cervical cancer in women and it is also r…

Complementary and Innovative Method in Genital HPV Testing for Cervical Cancer Prevention

2020

Abstract Considering actual SARS-COV 2 pandemic, the comfort and time of the female patient’ trend is to minimize the time spent in the doctor’s office, so that auto-testing is a solving problem in this context. This paper aims at the importance of self-collected urine and vaginal samples, since actual studies are showing that is a complementary method in HPV-testing and a screening method for prevention of cervical cancer. Genital HPV infection is responsible for approximately 99% of cervical cancers, and is considered a sexually transmitted disease. Given that eight out of ten patients have at least one episode of HPV infection in their lifetime, there is a need for a method of early dete…

Low rate of oral human papillomavirus (HPV) infection in women screened for cervical HPV infection in Southern Italy: A cross-sectional study of 140 …

2009

Even though the natural history of cervical and oral human papillomavirus (HPV) infection has been investigated intensely, the possibility that HPV may infect both sites in the same subject is not well documented. This study investigated the frequency of concurrent oral and cervical HPV infection in southern Italian women, in the light of some selected socio-behavioral variables. One hundred forty women (mean age: 36 years), with known cervical HPV status, were analyzed for oral HPV. Age, smoking/drinking habits, clinical and socio-behavioral history were assessed by personal interviews. Oral mucosal cells were collected by oral brushing and HPV DNA was sought by the use of nested PCR ampli…

Electron transfer mechanism in Shewanella loihica PV-4 biofilms formed at graphite electrode

2012

Abstract Electron transfer mechanisms in Shewanella loihica PV-4 viable biofilms formed at graphite electrodes were investigated in potentiostat-controlled electrochemical cells poised at oxidative potentials (0.2 V vs. Ag/AgCl). Chronoamperometry (CA) showed a repeatable biofilm growth of S. loihica PV-4 on graphite electrode. CA, cyclic voltammetry (CV) and its first derivative shows that both direct electron transfer (DET) mediated electron transfer (MET) mechanism contributes to the overall anodic (oxidation) current. The maximum anodic current density recorded on graphite was 90 μA cm − 2 . Fluorescence emission spectra shows increased concentration of quinone derivatives and riboflavi…
