The use of Wireless Sensor Networks (WSN) associated with the reality of an Internet of Things (IoT) scenario in nuclear environments is a growing security concern. In this context, standards are intensified to preserve the physical integrity of these facilities considered to be highly critical due to the size of the impacts of safety accidents. This paper presents a proposal to build a methodology to evaluate the security levels of WSNs with IoT devices when used in nuclear areas. The proposal is initially based on related work to establish a more concrete initial framework and is structured in consistent steps from previous scientific studies.

Corynebacterium pseudotuberculosis is an infectious agent that occurs in small ruminants causing caseous lymphadenitis, and more rarely in humans causing lymphadenitis and pneumonia. The breeding small ruminants have great economic importance in Brazil. Rural farm workers and veterinary students who acquired this disease suffered from weakening symptoms for weeks, and the identification of the etiological agent was time-consuming and complex. Due to the low prevalence of case records, there is probably no available commercial diagnostic kit for C. pseudotuberculosis infection in humans. This study aimed to describe human seroreactivity to secreted antigens from C. pseudotuberculosis. Reactivity of serum from farm workers (n = 14), individuals who work with the bacillus at laboratory (n = 8) or individuals without contact (n = 25) was tested with secreted proteins from PAT10 strain of C. pseudotuberculosis by Western blotting. Samples of all (100%) farm workers showed reactivity to 31 kDa, 71 kDa and 164 kDa proteins, while laboratory workers showed 87.5%, 62.5 % and 37.5%, and no-contact 20%, 0% and 16%, respectively. All sera recognized the 275 kDa protein. Our data suggest that C. pseudotuberculosis secreted proteins are antigenic in humans and the recognition profiles allowed the identification of individuals with and without prior contact with this bacillus. This is the first paper which describes human reactivity to C. pseudotuberculosis in serum samples of workers in Brazil.

Correlations for the extension of a water vapor jet injected in a liquid pool were historically proposed considering the mass flux (kg/m2/s) as a constant. The results were satisfactory, however adjusting the values by linear regression. Although, it presents the following drawbacks: 1) the formulation is only valid for the specific range of data for what it was created;2) it does not allow the analytical evaluation of the heat transfer coefficient from the extension equation. This paper proposes a new formulation for the calculation of the mass flux, in such a way to remove both of these drawbacks.

We present a case of a patient with hypersplenism secondary to portal hypertension due to hepato-splenic schistosomiasis, which was accompanied by severe and refractory thrombocytopenia. We performed spleen ablation and measured the total spleen and ablated volumes with contrast-enhanced computed tomography and volumetry. No major complications occurred, thrombocytopenia was resolved, and platelet levels remained stable, which allowed for early treatment of the patient's underlying disease. Previous work has shown that splenic radiofrequency ablation is an attractive alternative treatment for hypersplenism induced by liver cirrhosis. We aimed to contribute to the currently sparse literature evaluating the role of radiofrequency ablation(RFA) in the management of hypersplenism. We conclude that splenic RFA appears to be a viable and promising option for the treatment of hypersplenism.

In pregnant women subjected to spinal anesthesia for a Cesarean section, episodes of nausea and vomiting are common both during and following surgery. Acupuncture for the prophylaxis and treatment of these complications has been gaining in popularity due to its low cost, simplicity, absence of side effects and confirmed efficacy. This study investigated the efficacy of stimulating the P6 acupoint in conjunction with the use of dexamethasone as prophylaxis for nausea and vomiting in pregnant women submitted to spinal anesthesia for a Cesarean section. The patients (n = 100) were randomly distributed into two groups. In the first group (n = 50), a site located one centimeter laterally from P6 was stimulated. This is not a true acupuncture point (sham acupuncture). In the second group (n = 50), P6 was stimulated. In both groups, 4 mg of dexamethasone were administered intravenously. A questionnaire was used to obtain information on the occurrence of nausea and vomiting during surgery and in the first 12 hours postpartum. The chi-square test and Fisher’s exact test were used to assess differences between the groups. Age and physical status were similar in both groups. The incidence of nausea during surgery was 32% (n = 16) in the control group and 22% (n = 11) in the P6 group (p > 0.05). In the first 12 hours following surgery, nausea occurred in 16% of the women in the control group (n = 6) and in 4% in the P6 group (n = 4) (p = 0.045). The incidence of vomiting in the control group was 12% (n = 6) during surgery and 10% (n = 5) in the postoperative period compared to 8% (n = 4) and 4% (n = 2), respectively, in the P6 group (p > 0.05). Although these differences were not statistically significant with the exception of the incidence of nausea in the first 12 hours postpartum, a reduction occurred in the incidence of all the outcomes evaluated in the P6 group.

本研究的目的是在体内评价渗透树脂(IR)治疗釉质白垩斑(WSLs)的即时遮盖效果。研究对象为40名11~23岁的青少年和年轻成人.至少有一颗上颌或下颌恒前牙为活动性白垩斑(ICDAS得分为2分)。在渗透树脂治疗前.使用数字分光光度计(CIElab)对白垩斑和相邻完整釉质(SAE)的颜色进行评估。接着.依据生产商的使用说明对白垩斑应用渗透树脂技术(Icon).临床操作结束时评估渗透树脂的颜色。计算白垩斑和相邻完整釉质(WSL×SAE)、白垩斑和渗透树脂(WSL×IR)以及渗透树脂和相邻完整釉质(IR×SAE)间的颜色差异(△E),然后用单因素方差分析和Turkey’s检验进行分析。用t检验来比较相关样本白垩斑.相邻完整釉质和渗透树脂的L^*、a^*、b^*值(α=5%)。白垩斑和渗透树脂(WSL×IR)比较时△E=5.930.41.渗透树脂和相邻完整釉质间(IR×SAE)的△E=5.770.41.说明治疗后白垩斑的颜色发生改变.但与相邻完整釉质相比.渗透树脂不能完全掩饰白垩斑。相邻完整釉质的明度比渗透树脂高。由此可以得出如下结论:与相邻完整釉质相比.渗透树脂治疗不能遮盖白垩斑的颜色.但可以减弱釉质脱矿引起的变色。

Phosphate fertilizers when applied to the soil, besides being harvested by the crops, promote a residual effect that can be offered to subsequent crops. The objective of this research was to evaluate the residual effect of phosphate fertilization applied to maize cultivation on the successor crop, cowpea, in the Cerrado region in Maranhao. The research was carried out in the experimental area of Federal University of Maranhao (UFMA), located in the city of Chapadinha, MA (3°44'30"S, 43°21'37''W). The experimental design was in randomized blocks, with six treatments and four replications. The treatments were composed of the following residual P doses: 0, 60, 70, 80, 90, 100 kg·ha-1 of P2O5. The cultivation of cowpea (cultivar BRS guariba) was sown at a spacing of 1.0 × 0.20 m. The cowpea proved to be efficient in the use of residual phosphate fertilization, since it promoted grain yield close to the national average. The cultivation of cowpea in previously cultivated areas is feasible, in order to take advantage of the residual phosphate fertilization in the Cerrado of East of Maranhao. The phosphorus dose applied in the predecessor crop corresponding to 80 kg·ha-1 of P2O5 promoted higher grain yield (393.44 Mg·ha-1) and a greater profit margin (US $326.26). Thus, it is feasible to grow cowpea in previously cultivated areas, in order to take advantage of residual phosphate fertilization.
