Abstract The Solar Physics Group at the INAF-Turin Astrophysical Observatory (OATo) is actually involved in different Space Weather (SW) projects and missions. In particular, this Group is currently providing for the ESA SWESNET portal two new data analysis tools aimed at (1) the automated identification of magnetic flux ropes from the in situ data (CME magnetic effectiveness tool) and (2) the automated identification and arrival prediction of CMEs from remote sensing and in situ data (CME propagation and forecast tool). The Group is also developing numerical tools for future applications of interest for SW under the project SWELTO-Space WEather Laboratory in Turin Observatory. Moreover, the Group is participating in two SW missions, and in particular in Helianthus (research and development project on solar photonic propulsion for early SW warnings) and Selene (Solar Exploration by Lunar Eclipsing with Nanosatellites Experiment). In addition to this, the Group is leading or is involved in other “SW enabling science” projects, and in particular the Metis coronagraph on-board ESA Solar Orbiter mission, the ASPIICS coronagraph on-board ESA PROBA-3 mission, and the CorMag coronagraph on-board HEMERA stratospheric balloon. In this framework, the OATo Solar Physics Group is working on fundamental research on “SW enabling science”, dealing with the origin and acceleration of solar wind and Coronal Mass Ejections with remote-sensing data, and their interplanetary propagation and evolution with in situ data.

Chlorophenols are the persistent organic contaminants released in the aquatic bodies by industrial manufacturing units. Treatment of phenolic wastewater is an arduous process for conventional treatment methods because of their high stability and complexity. The present study deals with degradation of 2,4,6-Trichlorophenol, using Photo-Fenton’s process. The study commences the optimisation and validation of different regulating parameters like pH, oxidant (H2O2), and Fe2+ ions at variable concentration in batch mode. At pH 3.0, Fe2+ 0.5 mM, and H2O2 (10.0 mM), complete degradation of trichlorophenol was observed within 6 min of reaction time. The mineralisation of the model pollutant was studied over TOC analyser and HPLC. Response Surface Plots were drawn to define the interactive relationship between process governing Fenton’s process. Under optimized conditions, different Fenton-integrated processes, such as Solar-Fenton, Sono-Fenton, and Sono-Photo-Fenton (UV365), were compared for degradation of TCP. Among all the processes, Solar-Fenton resulted in rapid and complete degradation of TCP within 5 min. The mineralisation efficiency of Fenton’s process, Solar-Fenton, Sono-Fenton, Sono-Photo-Fenton, and Photo-Fenton’s processes were 50%, 98%, 90%, 75%, and 50%, respectively. The results indicated Solar-assisted Fenton as potential and efficient approach toward degradation of Trichlorophenol.
氯酚是工业生产单位排放到水体中的持久性有机污染物。由于酚类废水的高稳定性和复杂性,传统的处理方法对其的处理是一个艰巨的过程。本研究采用光fenton法降解2,4,6-三氯苯酚。本研究开始对不同的调节参数如pH、氧化剂(H2O2)和Fe2+离子在不同浓度的批处理模式下进行优化和验证。在pH 3.0、Fe2+ 0.5 mM和H2O2 (10.0 mM)条件下,反应时间为6 min,三氯苯酚被完全降解。通过TOC分析仪和HPLC对模型污染物的矿化进行了研究。绘制响应面图来定义控制芬顿过程的过程之间的交互关系。在优化条件下,比较了Solar-Fenton、Sono-Fenton和Sono-Photo-Fenton (UV365)等不同fenton集成工艺对TCP的降解效果。其中,Solar-Fenton可在5 min内快速完全降解TCP。Fenton法、Solar-Fenton法、Sono-Fenton法、Sono-Photo-Fenton法和Photo-Fenton法的矿化效率分别为50%、98%、90%、75%和50%。结果表明,太阳能辅助Fenton是一种有潜力的高效降解三氯酚的方法。

Flavored olive oils were generally produced with the maceration method, which has disadvantages such as taking a long time and making the tanks unusable for a long time. The new techniques could produce flavored oils to shorten time according to maceration. In this work, three different olive oil types, including extra-virgin olive oil (EVOO), refined olive oil (RO), and refined olive pomace oil (RPO) as oil sources and five plant materials (Tulsi, Thyme, Marjoram, Rosemary and Oregano) as flavoring materials were selected and subjected to a heating process in a microwave oven for a duration of 6, 8, 10, and 15 min at a constant frequency of 2450 MHz and a power of 0.45 kW to produce flavored oils and also used maceration technique. The presence of 4 PAH components, such as benzo(a)pyrene (B[a]P), benzo[a]anthracene (B[a]A), benzo(b)fluoranthene (B[b]F), and Chrysen (Chr), classified as dangerous for health was measured in the oils that were macerated and microwaved. In macerated oils, only B[a]P was detected in flavored RPOs. However, B[a]P and Chr were detected in all flavored oils, especially in a long-time microwave (10 and 15 min). Besides, B[a]A and B[b]F were found in only flavored RPOs with an increase in exposure time (10 and 15 min). The concentration of B[a]P detected in four samples, including the control sample (CRPO) and flavored samples, was above the limit value of 2 µg/kg. On the other hand, the total content of the four PAHs: B[a]P, B[a]A, B[b]F and Chr did not exceed the limit value of 10 μg/kg. As a result, PAHs are higher in extended exposure to microwave applications in flavored olive oils, compared to the conventional maceration method, resulting in lower-quality products regarding food safety.
风味橄榄油的生产一般采用浸渍法,浸渍法存在浸渍时间长、储罐长期不能使用等缺点。新工艺可通过浸渍生产风味油,缩短时间。橄榄油在这个工作中,三个不同的类型,包括特级初榨橄榄油(EVOO)、精制橄榄油(RO)和精制橄榄果渣油(RPO)作为油源和五个植物材料(坦、百里香、马郁兰、迷迭香和牛至)调味材料选择和接受在微波炉加热过程持续时间6、8、10和15分钟以一个恒定的频率2450兆赫和0.45千瓦的电力生产调味油,也用浸渍技术。在浸渍和微波处理的油中测量了4种多环芳烃成分的存在,如苯并(a)芘(B[a]P)、苯并(a)蒽(B[a] a)、苯并(B)荧光蒽(B[B]F)和Chrysen (Chr),这些成分被列为对健康有害。在浸渍油中,风味RPOs中仅检测到B[a]P。然而,在所有调味油中都检测到B[a]P和Chr,特别是在长时间微波(10和15 min)中。此外,B[a] a和B[B]F只存在于有香味的RPOs中,随暴露时间增加(10和15 min)。对照品(CRPO)和调味品4个样品中B[a]P含量均超过2µg/kg的极限值。另一方面,B[a]P、B[a] a、B[B]F和Chr 4种多环芳烃的总含量均未超过10 μg/kg的限值。因此,与传统的浸渍方法相比,在调味橄榄油中长时间暴露于微波中,多环芳烃含量更高,导致食品安全方面的产品质量降低。

Abstract To investigate the statistical properties of the photospheric magnetic fields underlying coronal holes (CHs) and “normal” coronal regions a classical technique, the signed measure, is used. This technique allows to characterize the scaling behavior and the topology of sign-oscillating magnetic structures in selected regions of line of sigth (LoS) magnetograms recorded by the Heliosismic Magnetic Imager on board of the Solar Dynamic Observatory (SDO/HMI). To this end we have compared the properties of the photospheric magnetic field underlying 60 CHs and 60 non-coronal holes (NCHs). In particular, in addition to having studied distributions and momenta of photospheric magnetic fields associated to the selected regions, we have performed the sign singularity analysis computing the cancellation functions of the highly fluctuating photospheric magnetic fields. We have found that photospheric magnetic fields associated to CHs are imbalanced in the sign and that this imbalance emerges mainly at the supergranular scales.
摘要为了研究日冕洞(CHs)和“正常”日冕区域下的光球磁场的统计特性,采用了经典的符号测量方法。该技术允许表征尺度行为和符号振荡磁结构的拓扑结构在选定区域的视线线(LoS)磁图记录由太阳动力天文台(SDO/HMI)板上的日冕磁成像仪。为此,我们比较了60个日冕洞和60个非日冕洞的光球磁场特性。特别地,除了研究与选定区域相关的光球磁场的分布和动量外,我们还进行了符号奇点分析,计算了高度波动的光球磁场的抵消函数。我们发现与CHs相关的光球磁场在信号中是不平衡的,这种不平衡主要出现在超颗粒尺度上。

The study aimed to develop and analyze a conjugated zinc Nano particle formulation that would enhance its anti-cirrhosis activity by increasing its bioavailability and release. Standard characterization procedures were used to create and analyze zinc nano particles (ZNPs). Drug release and hepatic cirrhosis model testing were conducted on rats utilizing the enhanced formulation. For 30 days, ZnNPs were supplied through oral gavage. For biochemical examination of serum samples, rats were anesthetized and slaughtered after the research. The expression of genes and microRNAs (miRNAs) in liver tissues was studied; together with expression of liver specific genes and inflammatory markers. These findings were also validated by liver tissue histological and immune histochemical (IHC) studies. Measuring techniques demonstrated the practical synthesis and conjugation of ZnNPs. Nanohybrid ZnNPs showed significant anticirrhosis therapeutic activity. ZnNPs' anti-cirrhosis properties decrease TGFR1 and COL3A1 expression, because they enhance the production of miRNAs that protect against cirrhosis. Furthermore, the expression of cancer markers (AFP, p53) was down/up-regulated in ZnNPs treated groups. Similarly, the pro- and anti-inflammatory markers expressions were found normalized in ZnNPs groups compared to untreated groups. These results were further validated by histopathology and IHC analysis, which showed that ZnNPs have anti-fibrotic properties. We finally, conclude that the that we achieve loading capacity of 94%, 36.63%, respectively, in the successful synthesis of ZnNPs. Furthermore, ZnNPs exhibits in vivo hepato-protective activity by down-regulating hepatic cancer markers and upregulating hepatic functional markers which assure the use of ZnNPs for the treatment of liver cirrhosis in future studies.
该研究旨在开发和分析一种共轭锌纳米颗粒配方,通过增加其生物利用度和释放度来增强其抗肝硬化活性。采用标准表征程序制备和分析锌纳米颗粒。采用增强制剂对大鼠进行药物释放和肝硬化模型试验。灌胃给药30 d。研究结束后,将大鼠麻醉后屠宰,进行血清生化检验。研究肝组织中基因和microrna (miRNAs)的表达;以及肝脏特异性基因和炎症标志物的表达。这些发现也得到了肝组织组织学和免疫组织化学(IHC)研究的证实。测量技术证明了ZnNPs的合成和共轭的实用性。纳米杂化ZnNPs具有显著的抗肝硬化治疗活性。ZnNPs的抗肝硬化特性降低了TGFR1和COL3A1的表达,因为它们增强了保护肝硬化的mirna的产生。此外,在ZnNPs处理组中,癌症标志物(AFP, p53)的表达下调/上调。同样,与未治疗组相比,ZnNPs组的促炎性和抗炎标志物表达正常化。组织病理学和免疫组化分析进一步验证了这些结果,表明ZnNPs具有抗纤维化特性。最后,我们得出结论,在成功合成的ZnNPs中,我们分别达到了94%和36.63%的负载能力。此外,ZnNPs通过下调肝癌标志物和上调肝功能标志物显示出体内肝保护活性,这保证了ZnNPs在未来研究中用于治疗肝硬化。

We finally, conclude that the that we achieve loading capacity of 94%, 36.63%, respectively, in the successful synthesis of ZnNPs. Furthermore, ZnNPs exhibits in vivo hepato-protective activity by down-regulating hepatic cancer markers and upregulating hepatic functional markers which assure the use of ZnNPs for the treatment of liver cirrhosis in future studies.","PeriodicalId":54501,"journal":{"name":"Rendiconti Lincei-Scienze Fisiche E Naturali","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136192586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Tazekka Variscan massif is formed by Meso-Cenozoic cover unconformably overlying the Paleozoic rocks recording polyphase tectonic stages contemporary with the emplacement of the magmatic system such as rhyolitic lavas and microdioritic dyke swarms attributed to the Upper Paleozoic tectonic phases and alkaline basaltic lavas attributed to Plio-Quaternary age. The mesostructural and tectonic analyses associated with paleo stress reconstruction are mainly based on the processing of tectonic measurement of slickensides fault planes with striation pitch determined by inversion of fault-slip data and allowed us to highlight the following tectono-magmatic events: (i) the Visean–Namurian phase is divided into two tectonic episodes. The first episode is characterized by NW–SE trending extension, while the second is marked by a relatively minor subhorizontal σ1 compressive axis oriented NE–SW (σ1–σ2 permutation). This latter episode controls the tectonic dislocation of Paleozoic rocks and the emplacement of a few rhyolitic lava flows along submeridian strike-slip faults; (ii) in the Stephanian–Permian age, the tectonic regime changes to a compressive stress state with a horizontal NE–SW trending σ1 axis and a horizontal NW–SE trending σ3 axis, which is what causes the development of NW–SE and NE–SW to ENE–WSW faults filled with microdioritic dyke swarms; (iii) the Permian–Lower-Middle Triassic period was marked by a compressive regime with a horizontal NNW–SSE to submeridian trending σ1 axis and a horizontal ENE–WSW to subequatorial trending σ3 axis, as well as NNE–SSW, WNW–ESE faults, and submeridian microdioritic tension gashes. The compression changes to WNW–ESE during the Vallesian or Lower Pliocene age. Early-Middle Quaternary is divided into two tectonic episodes with a σ1–σ2 axis permutation. Its axis changes from NNW–SSE associated with the ENE–WSW extension and is characterized by NE–SW faults affecting basaltic lavas. Subequatorial strike-slip faults, submeridian normal faults, and Late-Variscan brittle tectonic structures are mostly filled by basaltic lavas.
Tazekka Variscan地块是由中新生代不整合盖层覆盖在古生代岩石上形成的,这些古生代岩石记录了与上古生代流纹熔岩和微闪长岩脉群以及上第四纪碱性玄武岩熔岩等岩浆体系侵位同时代的多期构造阶段。与古应力重建相关的细观构造和构造分析主要基于滑面断面的构造测量处理,并通过断层滑动数据反演确定了条纹节距,从而突出了以下构造-岩浆事件:(1)维桑—纳慕良期分为两个构造期。第一期以NW-SE向伸展为特征,第二期以相对较小的次水平向σ1压缩轴向NE-SW (σ1 -σ2排列)为特征。后一阶段控制了古生代岩石的构造错位和少量流纹岩熔岩流沿水下走滑断层的侵位;(ii) Stephanian-Permian时代,构造体制转变为水平NE-SW向σ1轴和水平NW-SE向σ3轴的压应力状态,导致NW-SE和NE-SW至ENE-WSW断裂发育,并充满微闪长岩脉群;(3)二叠统—中三叠统时期形成了以NNW-SSE—淹没向σ1轴和ENE-WSW—亚赤道向σ3轴为特征的水平挤压体系,形成了nne—ssw、wnw—ese断裂和淹没微闪长岩张拉裂缝。在瓦列世或下上新世,压缩向西北西东-东西方向转变。早-中第四纪分为两个构造期,呈σ1 -σ2轴排列。其轴线由NNW-SSE转变,与ENE-WSW伸展有关,以NE-SW断裂影响玄武岩熔岩为特征。潜下走滑断裂、潜下正断层和晚瓦里西世脆性构造多由玄武岩熔岩充填。
