A continuous real parameter q is characterizing them so that, in the range 1<q<3, the q-functions pass from the usual Gaussian form, for q close to 1, to that of a heavy tailed distribution, at q close to 3. The value q=2 corresponds to the Cauchy-Lorentzian distribution. This behavior of q-Gaussian functions could be interesting for a specific application, that regarding the analysis of Raman spectra, where Lorentzian and Gaussian profiles are the line shapes most used to fit the spectral bands. Therefore, we will propose q-Gaussians with the aim of comparing the resulting fit analysis with data available in literature. As it will be clear from the discussion, this is a very sensitive issue. We will also provide a detailed discussion about Voigt and pseudo-Voigt functions and their role in the line shape modeling of Raman bands. We will show a successfully comparison of these functions with q-Gaussians. The role of q-Gaussians in EPR spectroscopy (Howarth et al., 2003), where the q-Gaussian is given as the ''Tsallis lineshape function'', will be reported. Two examples of fitting Raman D and G bands with q-Gaussians are proposed too.","PeriodicalId":14423,"journal":{"name":"International journal of sciences","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88605037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: The penis can be affected by several pathologies, including Peyronie's Disease (PD), a condition characterized by structural alterations caused by disorders that occur during tunica albuginea healing. Several clinical treatment options exist for the management of this pathology, however the benefits of many have not been proven scientifically. The objective of this study was to investigate the management and follow-up of Peyronie's disease patients in order to identify the treatments provided and the respective degrees of patient satisfaction. Over 18-year-old male patients with early onset Peyronie's disease (less than three months) treated at an outpatient urological clinic between 2015 and 2020 were retrospectively studied. Results: The most commonly used treatment was the combination of pentoxifylline, vitamin E and colchicine (44%). There is evidence of a significant association between the type of clinical treatment used and the results of surgery. Although 37.2% of the patients had surgical complications, 32 of the 43 individuals who underwent the surgical procedure were satisfied with the results. Conclusions: Treatment satisfaction of Peyronie's disease patients was higher for those submitted to surgical treatment compared to clinical treatment.

Tsallis q-Gaussian functions are probability distributions possessing a shape which can be stretched from a Lorentzian to a Gaussian profile, according to the q-index parameter of their generalized exponentials. As we have previously shown, the q-Gaussian functions can be successfully applied to the deconvolution of Raman bands. Here we consider them for being used in the analyses of the Surface Enhanced Raman Scattering (SERS) spectral bands. The case studies here considered are the SERS spectra published by Sherman et al., in 2020, of L-Cysteine, Cysteamine and Homocysteine. Sherman and coworkers prepared these metabolites in silver colloids with sodium citrate.

Nutcracker Syndrome, a rare anatomical condition, consists of the compression of the Left Renal Vein as it passes at the Aortomesenteric level and results in nonspecific signs and symptoms. Its exact prevalence is unknown and can present at any age, with a peak prevalence between the second and third decade. Its diagnosis is of exclusion and is primarily through imaging tests, with Venography and pressure gradient measurement being the gold standard. Treatment varies according to clinical severity, ranging from conservative measures to surgical approach, either open or endovascular. The latter, despite being safer, can present various complications. In view of this, a literature review was conducted to analyze potential complications of endovascular treatment for Nutcracker Syndrome. A total of 21 articles correlating the complications of endovascular treatment for patients with this syndrome were found and included. Most studies presented restenosis, local fibromuscular hyperplasia, erosion, thrombus occlusion, and stent migration as the main and most common complications. Stent migration can lead to worse outcomes necessitating surgical reapproach. Nutcracker Syndrome, being rare, has few studies that follow the long-term outcomes of possible treatments. Among these, endovascular treatment is currently the most recommended as it is minimally invasive, but it is not failure-free, necessitating individualized stent choice and follow-up to reduce the incidence of various complications.

Understanding conservation attitudes of local communities is essential to the long -term survival of protected areas. Perception and attitudes towards protected areas may greatly be influenced by the various kinds of relationship that exists between the local communities and the protected area management. Studies that have focused on local people’s responses to protected areas indicate that attitudes towards protected areas and conservation in general are also greatly influenced by benefits obtained. This study aims to explore the factors influencing conservation attitudes of villagers who live near around the Popa Mountain Park (PMP) in Myanmar. A sample of 174 households was randomly selected from three villages adjoining the Park to collect the data using structured questionnaire interviews, focus group discussion with local residents and directly observation to the environment. Logistic regression analysis was applied to determine which significant factors influence in predicting attitude towards conservation. Logistic regression showed that forest dependency and limited access to forest resources are found to be significant predictors of conservation attitudes. The findings go along with most of similar studies that, providing alternative source of income for the livelihood through employment opportunities or by an income source from agricultural will greatly reduce the forest dependence. The research concluded that consideration to household socioeconomic characteristics near around the PMP is essential in protected area management. The study recommends that environmental education programme should be encouraged in order to reduce dependence on the protected forests. Moreover, the government should consider measures to increase agricultural production and generate off-farm employment opportunities for local communities in general and strengthen conservation activities especially around the Popa Mountain Park.

Understanding the costs and benefits of plantations can provide a better way for resources management in restoration area. This paper focuses on the net present value (NPV) and the internal rate of return (IRR) and benefit-cost ratio (BCR) for financial performance of the plantations. A combination of secondary information survey method and field survey method for data collection was carried out in this study. On the basis of an annual discount rate of 10%, the results indicate positive NPVs, pure teak plantation would attain the highest BCR and the acceptable NPV, but its IRR is smaller than agroforestry practice due to the discounting effect of late return over a long investment period. Pure teak plantation is found to be most profitable following by agroforestry practice (teak and turmeric) and pine plantation. From a pure financial point of view, plantations should be encouraged but its long-term productivity and adverse ecological effects have to be taken into account. It also needs systematically calculation to obtain high-quality timber in the final harvest of forest plantations, but also to obtain large volume of timber to satisfy more economic benefits. The results provide valuable information for plantation policy for the government.
