A new algorithm for unconstrained optimization based on the cubic regularization in two dimensional subspace is developed. Different strategies for search direction are also discussed. The stepsize is computed by means of the weak Wolfe line search. Under classical assumptions it is proved that the algorithm is convergent. Intensive numerical experiments with 800 unconstrained optimization test functions with the number of variables in the range [1000 - 10,000] show that the suggested algorithm is more efficient and more robust than the well established conjugate gradient algorithms CG-DESCENT, CONMIN and L-BFGS (m=5). Comparisons of the suggested algorithm versus CG-DESCENT for solving five applications from MINPACK-2 collection, each of them with 40,000 variables, show that CUBIC is 3.35 times faster than CG-DESCENT.
提出了一种基于二维子空间三次正则化的无约束优化算法。讨论了搜索方向的不同策略。通过弱Wolfe线搜索计算步长。在经典的假设条件下,证明了该算法是收敛的。对800个无约束优化测试函数(变量数在[1000 ~ 10000]范围内)进行的大量数值实验表明,该算法比已有的共轭梯度算法CG-DESCENT、CONMIN和L-BFGS (m=5)更高效、更鲁棒。将该算法与CG-DESCENT算法在求解MINPACK-2集合中的5个应用程序(每个应用程序都有40,000个变量)时的比较表明,CUBIC算法比CG-DESCENT快3.35倍。

The grasslands of Crișurilor Plain, the portion between Crișul Negru and Crișul Repede, located on flat lands with normal soils and different stages of salinity, generally have a lower productivity and biodiversity. The average number of cormophyte species is 50 with variations from 16 in Camphorosmetum annuae and Polygano-Plantaginetum tenuiflorae, to around 90 in Festucetum valesiacae, Artemisio and Achilleo - Festucetum pseudovinae. The overall vegetation cover is 86% with 44% forage species and 42% harmful species. The average pastoral value (PV) of the 18 associations is 30.8 (mediocre), the highest was 75.7 (good) in Lolietum perennis and the lowest 2.0 (degraded) in Camphorosmetum annuae. The average production of green mass (GMP) was evaluated at 5 t/ha with very large differences between the associations. At phytosociological alliances level, Festucion rupicolae (47.6 PV and 8.18 t/ha GMP) and Beckmanion erucaeformis (42.5 PV and 9.04 t/ha GMP) had the highest productivity and Cyperio - Spergularion (3.6 PV and 0.29 t/ha GMP) had the lowest. Finally, the productivity evaluation was done at the level of normal and degraded Natura 2000 Habitats (6440, 6240 and 1530). Habitat 6440 normal was rated at 65.7 PV (good) and 13.09 t/ha GMP, which allows for an optimal loading of 1.26 LU/ha (good). The worst results had the Habitat 1530 (degraded) with 5.7 PV and 0.51 t/ha GMP with the most saline soils and irrational use of grasslands. The results of these productivity evaluations of grasslands based on floristic surveys continue to serve for the preparation of pastoral arrangements and their proper management.
Crișurilor平原,即Crișul Negru和Crișul Repede之间的部分,处于正常土壤和不同盐度阶段的平坦土地上,一般具有较低的生产力和生物多样性。蕨类植物的平均种类为50种,其中樟树和金车前草的平均种类为16种,而长叶羊蹄草、蒿属植物和阿奇利奥-假羊蹄草的平均种类约为90种。总体植被覆盖度为86%,其中牧草种占44%,有害物种占42%。18个群落的平均牧灵值(PV)为30.8(一般),最高的是多年生Lolietum,为75.7(良好),最低的是香樟(Camphorosmetum annuae)为2.0(退化)。绿色质量(GMP)的平均产量被评估为5吨/公顷,协会之间差异很大。在植物社会学联盟水平上,荆芥(47.6 PV, 8.18 t/ha GMP)和Beckmanion erucaeformis (42.5 PV, 9.04 t/ha GMP)的生产力最高,Cyperio - spergulion (3.6 PV, 0.29 t/ha GMP)的生产力最低。最后,在正常和退化的Natura 2000生境(6440、6240和1530)水平上进行生产力评价。生境6440的正常负荷为65.7 PV(良好),GMP为13.09 t/ha,其最佳负荷为1.26 LU/ha(良好)。结果最差的生境1530(退化)PV为5.7,GMP为0.51 t/ hm2,土壤盐碱度最高,草地利用不合理。这些以植物区系调查为基础的草原生产力评价的结果继续为制定牧区安排及其适当管理服务。

"Through the double election, on January 5 and 24, 1859, through the extensive and complex program of reforms carried out during the 7 years of Alexandru Ioan Cuza's reign, the foundations of the modern Romanian national state were laid. The archive documents give us a correct picture of the events and personalities in the Buzău area. Following the elections of September 1857, the 7 deputies of Buzău county were: the bishop of Filotei, Scarlat Voinescu, Nicolae Pâcleanu, Costache Ciochinescu, Nae Stănescu, Vasile Serea and Costache Moglan. In accordance with those established in Buzău County, the members of the Elective Assembly were then elected, who on January 24, in the Concordia Hotel in Bucharest, together with the other Wallachian deputies, confirmed the double election of Alexandru Ioan Cuza. They were: Scarlat Voinescu, Ion (Iancu) Marghiloman, Costache Deşliu, Mihail Pleşoianu and the bishop of Filota. In the evening of February 6, 1859, ruler Alexandru Ioan Cuza was received by Buzoians with great pomp. A year later, on January 23, 1860, Prince Cuza celebrated the Union of the Romanian Principalities in Buzău."

This study reveals a very specific issue in the field of the international relations history. As a matter of fact, the Romanian State՚s emergency presupposed an international regime exposed through the joint guarantee of the European Great Powers, as signing parts of the Peace Treaty of Paris, from the 30s March 1856. The readings of that Treaty and of the many other papers proved the fact that the Guaranteeing Powers were the six European Great Powers, as France, Great Britain, Austria, Prussia, Russia, and Sardaigne. The Ottoman Empire, as suzeraine Court on the Romanian Principalities Moldavia and Wallachia, as well on Serbia, it was a guaranteed, and not a guaranteeing part. These revealings permitted some pointed understandings of the both international impact of the Romanian international acts, as, for example, the Union of the Principalities in 1859, and significations of the diplomatic European deliberations, as the Great Powers Concert on the Romanian Question.
这一研究揭示了国际关系史领域的一个非常具体的问题。事实上,罗马尼亚国家՚的紧急状态是以一种国际制度为前提的,这种国际制度是通过欧洲大国的共同保证而暴露出来的,从1856年3月30日起签署了《巴黎和平条约》的部分内容。对该条约和许多其他文件的解读证明了这样一个事实,即保证国是六个欧洲大国,即法国、英国、奥地利、普鲁士、俄国和萨达格。奥斯曼帝国,作为罗马尼亚摩尔达维亚和瓦拉几亚公国以及塞尔维亚的宗主国,它是有保障的,但不是有保障的一部分。这些启示使人们能够对罗马尼亚国际行动的国际影响,例如1859年公国联盟,以及欧洲外交审议的意义,例如关于罗马尼亚问题的大国协调会议,有一些尖锐的理解。

In this paper, we obtain the quantum dynamics in the framework of the general theory of relativity, where a quantum partide is described by a distribution of matter, with amplitude functions of the matter density, in the two conjugate spaces of the spațial coordinates and of the momentum, called wave functions. For a free partide, these wave functions are conjugate wave packets in the coordinate and momentum spaces, with time dependent phases proporțional to the relativistic lagrangian, as the wave velocities in the coordinate space are equal to the distribution velocity described by the wave packet in this space. From the wave velocities of the partide wave functions, we obtain lorentz’s force and the maxwell equations. For a quantum partide in electromagnetic field, we obtain dynamic equations in the coordinate and momentum spaces, and the partide and antiparticle wave functions. We obtain the scattering or tunneling rate in an electromagnetic field, for the two possible cases, with the spin conservation, or inversion
在本文中,我们得到了广义相对论框架下的量子动力学,其中量子粒子被描述为物质的分布,具有物质密度的振幅函数,在spațial坐标和动量的两个共轭空间中,称为波函数。对于自由粒子,这些波函数是坐标空间和动量空间中的共轭波包,具有与时间相关的相位proporțional,相对于相对论拉格朗日,因为坐标空间中的波速度等于该空间中的波包所描述的分布速度。由粒子波函数的波速,我们得到了洛伦兹力和麦克斯韦方程组。对于电磁场中的量子粒子,我们得到了在坐标和动量空间中的动力学方程,以及粒子和反粒子的波函数。我们用自旋守恒或反转,得到了电磁场中两种可能情况下的散射率或隧穿率

TRITICALE IMPROVEMENT: PROBLEMS AND PROSPECTS IN THE WEST PART OF ROMANIA 小黑麦改良:罗马尼亚西部地区的问题与前景
Pub Date : 2022-01-01 DOI: 10.56082/annalsarsciagr.2022.2.5

The paper highlights the progress in triticale crop becoming an important economically cereal in the world and also in the West part of Romania. The international research stimulated the Romanian triticale program in research centers Fundulea, Turda, Suceava and Timişoara University. The extension of the results from the demonstration fields was difficult; the optics of the farmers from a traditionally wheat-growing country had to be changed. Particular merits have had the specialists who, as students, saw and worked in the triticale experimental fields at the university, thus convincing themselves of its validity. In the western counties of Romania triticale represents 1.56% of agriculture area. It is cultivated on poorly acid soils and in farms with livestock sections. The area cultivated with triticale varies greatly. In the southern counties of Arad, Bihor and Timiş the surface represents 1.0% -1.5%. In Caraş Severin and in the northern counties it is 2.5% to 5.1% (Sălaj). On preluvi- and luvi- soils (pH-4.5) distrycambosoils, arenosoils (humus less than 2.2 %) the yield was 2.6 T/ha up to 4.5 T/ha, exceeding wheat and in some areas even corn. In the plain with more fertile soils (chernozem) the Robinson, Trimaso, Trismart and Tulus varieties passed over 9.0 T/ha (2021). The triticale average production/country increased from 2.5 T/ha (2007) to over 3.4 T/ha in the past 10 years and now to 4.6 T/ha. Most of the cultivated varieties originated from the Fundulea (Dr. Gh. Ittu). Farmers in the western part of Romania appreciate triticales, but they also have certain grievances that breeders strive to correct.
本文重点介绍了小黑麦作物在成为世界和罗马尼亚西部重要的经济谷物方面取得的进展。这项国际研究促进了Fundulea、Turda、Suceava和timiurioara大学研究中心的罗马尼亚小黑麦项目。示范田成果推广困难;这个传统的小麦种植国的农民必须改变他们的看法。特别值得一提的是,作为学生的专家们在大学里的小黑麦实验田里看到和工作过,从而说服了自己它的有效性。在罗马尼亚西部各县,小黑麦占农业面积的1.56%。它被种植在贫瘠的酸性土壤和农场的牲畜区。种植小黑麦的地区差别很大。在南部的阿拉德县、比霍尔县和蒂米茨县,地表占1.0% -1.5%。在卡拉伊-塞维林和北部各县,这一比例为2.5%至5.1% (surilaj)。在土壤前壤和土壤中(pH-4.5),分布在土壤中,砂壤(腐殖质低于2.2%)的产量为2.6 ~ 4.5 T/ha,超过了小麦,在某些地区甚至超过了玉米。在土壤较肥沃的平原(黑钙土),Robinson、Trimaso、Trismart和Tulus品种超过了9.0吨/公顷(2021年)。过去10年,小黑麦平均产量从2.5吨/公顷(2007年)增加到3.4吨/公顷以上,现在增加到4.6吨/公顷。大多数栽培品种起源于Fundulea (Dr. Gh。Ittu)。罗马尼亚西部的农民喜欢小黑麦,但他们也有一些不满,育种者努力纠正。

"Between 20 October 1858 and 5 January 1859 (according to the old calendar), Anastasie Panu was a member of the Three-Kaymakam rule, installed in Moldova under a provision of the Paris Convention on the definitive organization of the Romanian Principalities. He was, in that capacity and for that 77-day period, the most important Unionist politician, with a decisive role in the ""course"" of the Moldavian events that preceded the election of Alexandru I. Cuza as ruler. It is to him that we owe, to an overwhelming extent, the restoration of the freedom of the press (by reinstating Grigorie Al. Ghica's law of May 1856), the full affirmation of the country's autonomy through an effective exercise, ensuring a (relative) majority of the National Party in the Elective Assembly of Moldavia, the introduction of the letterhead of the United Principalities on all official documents; finally, through the so-called ""Panu Plan"", ""paving"" the road to the throne of Moldavia for Colonel Alexandru I. Cuza. Therefore, this Unionist leader should be given not only our modest presentation, but a monument more enduring than bronze - if we may paraphrase the ancient poet: and not (almost) the oblivion bequeathed by an unjust posterity."
在1858年10月20日至1859年1月5日之间(根据旧历法),Anastasie Panu是三个kaymakam统治的成员,根据关于罗马尼亚公国最终组织的巴黎公约的规定在摩尔多瓦安装。在那77天的时间里,他是最重要的联合派政治家,在选举亚历山大·库扎(Alexandru I. Cuza)为统治者之前的摩尔多瓦事件的“进程”中发挥了决定性作用。我们在很大程度上归功于他,恢复了新闻自由(通过恢复格里戈里·阿尔·吉卡1856年5月的法律),通过有效的行使充分肯定了国家的自治,确保了民族党在摩尔达维亚选举议会中占(相对)多数,在所有官方文件上采用了公国联合的信纸;最后,通过所谓的“帕努计划”,为亚历山德鲁·库扎上校铺平了通往摩尔达维亚王位的道路。因此,这位统一党领袖不仅应该得到我们的谦逊的介绍,而且应该得到一座比青铜更持久的纪念碑——如果我们可以转述古代诗人的话:而不是(几乎)被不公正的后代所遗忘。”

The need to ensure the protection of plants and various areas affected by the presence of pests and pathogens imposed the use of chemicals to help in diminishing crop damages, namely pesticides. As Persistent Organic Pollutants (POPs), pesticides are resistant chemicals to bio(degradation), their residues being difficult to be removed from the environment. This papers discuss the state of investigations on the presence of pesticides in the environment, their behavior determined by their characteristics, types of pesticides used, the sources from which the pesticides can come. Also some threats that pesticides can generate in the environmental compartments (water, air, soil, sediments) are discussed in correlation with some specific properties of pesticides. A distinct section is dedicated to the presence and behavious of pesticides in fruit and vegetables, the residues found in some plant products according to European Food Safety Authority (EFSA). This analysis generates the support for the identification and characterization of impacts and risks on human health generated by the consumption of plants containing pesticide residues.
由于需要确保保护植物和受虫害和病原体影响的各个地区,因此必须使用化学品,即杀虫剂,以帮助减少对作物的损害。农药作为持久性有机污染物(POPs),是一种抗生物降解的化学物质,其残留物难以从环境中去除。本文论述了环境中农药存在的调查现状,农药的特性决定了农药的行为,农药的使用类型,农药的来源。并结合农药的一些特性,讨论了农药在环境隔间(水、空气、土壤、沉积物)中可能产生的威胁。根据欧洲食品安全局(EFSA)的说法,在一些植物产品中发现的残留,水果和蔬菜中农药的存在和行为是一个独特的部分。这一分析为查明和确定食用含有农药残留的植物对人类健康产生的影响和风险提供了支持。

ROMANIAN CONTRIBUTIONS TO THE GENERAL THEORY OF LAW AND THE PHILOSOPHY OF LAW IN THE FIRST HALF OF THE XXth CENTURY 20世纪上半叶罗马尼亚人对一般法律理论和法律哲学的贡献
Pub Date : 2022-01-01 DOI: 10.56082/annalsarsciphil.2022.1-2.49
Viorel Miulescu
It is of utmost importance that the evolution of the general theory and philosophy of law in the first half of the XXth century establishes their scientific and philosophical foundation within the framework of the juridical culture and practice of the epoch, bringing a valuable contribution to the field of the national and European legal doctrine which is valid even nowadays. Moreover, we can also state that the evolution of the general theory and philosophy of law during this interval coincided with the realization of the ideals of national unity and of a modern, democratic society in Romania. Outstanding personalities such as Nicolae Titulescu, Mircea Djuvara, Dumitru Drăghicescu a.s.o. contributed to the fulfilment of these ideals both through their scientific work and their juridical, political or diplomatic activity.
最重要的是,20世纪上半叶的一般法律理论和法律哲学的演变在当时的司法文化和实践框架内建立了它们的科学和哲学基础,为国家和欧洲的法律学说领域带来了宝贵的贡献,即使在今天也是有效的。此外,我们还可以指出,在这段时间内,一般理论和法律哲学的发展与罗马尼亚实现民族统一和现代民主社会的理想是一致的。诸如尼古拉·蒂图列斯库、米尔恰·朱瓦拉、杜米特鲁·德雷尔切切斯库等杰出人士也通过他们的科学工作和他们的司法、政治或外交活动为实现这些理想作出了贡献。
