This study reflects the specificities of family small- and medium-sized enterprises （SMEs） which are related to values, culture, and relationships with the territory （local context）. In the following sustainable and corporate social responsibility （CSR）-oriented strategies, family businesses are ＂assisted＂ by the presence of entrepreneurial values which are tied to and derived from the social system in the territory in which they are located. The aim of this study is to demonstrate that the consolidation of stable and durable relations between the family business and the local context depends on the presence of shared values between the members of the family and the stakeholders, all components of civil society are within the same territory. Such values are the fruit of a given territory＇s civic traditions. They are the result of an anthropological culture which is typical of the socioeconomic environment in which the entrepreneur, the family, and the business are all rooted, thus, they are expressions of a culture ＂of the place＂.

AIM: This prospective study evaluated the effectiveness of 90 W argon plasma coagulation (APC) for the ablation of Barrett's esophagus (BE) that is considered to be the main risk factor for the development of esophageal ***: The results from 25 patients, observed at the First Department of General Surgery, University of Verona, Italy, from October 2000 to October 2003, who underwent APC for histologically proven BE were prospectively ***: The ablation treatment was completed in all the patients but one (96%). The mean number of APC sessions needed to complete ablation was 1.6 (total number: 40). The eradication was obtained in the majority of cases by one session only (60%), two sessions were required in 24% of the cases and three or more in 16%.About 43% of the sessions were complicated. Retrosternal pain (22.5%) and fever (17.5%) were the most frequent symptoms. Only one major complication occurred, it was an hemorrhage due to ulcer formation on the treated esophagus that required urgent endoscopic sclerosis and admission. The follow-up was accomplished in all the patients with a mean period of 26.3 mo and 20 patients (84%) with a follow-up period longer than 24 mo. Only one patient showed a relapse of metaplastic mucosa 12 mo after the completion of ablation. The patient was hence re-treated and now is free from recurrence 33 mo ***: High power setting (90 W) APC showed to be safe and effective. The effects persist at a mean follow-up period of two years with a comparable cost in term of complications with respect to standard power settings. Further studies with greater number of patients are required to confirm these results and to assess if ablation reduces the incidence of malignant progression.

文物和艺术品的无损分析是文化遗产科技保护的重点和难点。该研究使用了一种遥感领域的地物光谱仪——便携式全波段高光谱感应器(Analytical Spectral Devices FieldSpec FR Pro 3)分析文物中常用的有机胶料。这种高光谱感应器可以在0.2 s内获得一个350~2500 nm全波段反射光谱,其波段涵盖了可见光、近红外和短波红外三个区域。该研究选取蛋黄、兔皮胶、亚麻籽油三种中西方古代、现代常用的胶结物作为研究对象,分别以单组分、与不同颜料的混合物两种形式来验证该设备无损分析的可靠性和实用性。首先按照传统绘画技法,使用四种不同颜料与上述胶结物的组合制备彩绘样品。待样品完全干燥后,使用探头直接接触法获取光谱信息,并利用相关软件进行数据处理。实验发现,由于物化本质不同,这三种胶结物的反射光谱在波长1100~2400 nm范围内的特征信息差异最为显著。当胶料与无机颜料混合后,这三种有机物的吸收峰位置相对于单组分出现了相同的三种变化:(1)波长1507 nm处的肩峰消失;(2)波长约为1943~1922 nm处的宽峰偏移;(3)位于波长2050 nm处的原N—H伸展和弯曲合频峰向右移动了约(20~2070 nm)。值得注意的是,C—H合频和倍频峰在单组分与混合物光谱中的位置保持一致。这一系列谱图变化规律使得从混合物中鉴别胶料具有了可能性。尽管在某些情况下,和其他光谱分析技术类似,混合后无机颜料和有机胶料吸收峰之间的相互干扰会影响胶料的鉴定,但利用其一阶导数光谱能够协助各组分的准确表征。结果表明,该高光谱感应器能够有效鉴别有机胶料;这种快速、无损的分析方法不仅在实验室成分分析中具有可行性,而且其便携的特点也适用于文物保护与修复现场的快速分析,具有较好的实用性。

We considerer parabolic partial differential equations: under the conditions , on a region . We will see that an approximate solution can be found using the techniques of generalized inverse moments problem and also bounds for the error of estimated solution. First we transform the parabolic partial differential equation to the integral equation . Using the inverse moments problem techniques we obtain an approximate solution of . Then we find a numerical approximation of when solving the integral equation , because solving the previous integral equation is equivalent to solving the equation .
