There are strict regulatory requirements for pipeline construction at river and stream crossings. The requirements for monitoring, surveillance and maintenance of existing crossings on the other hand are limited to a few lines in Section 10 of CSA Z662-99. Systematic procedures for assessing stream channel stability are not readily available to the operators of pipelines. As a consequence, many monitoring and inspection programs focus more on detecting exposures than on preventing them. In this paper, the AEC Pipelines Ltd. approach to monitoring river and stream crossings is reviewed and discussed. The program involves application of basic geomorphic concepts and use of aerial photographs to define channel characteristics at crossing sites and to determine which crossings may be subject to future channel instability or erosion problems. From these in-house evaluations, decisions are made to either proceed with more in-depth assessments by river engineering specialists or continue with routine aerial and ground surveillance. As part of the overall program, procedures for completing routine channel surveys and a checklist of data to be gathered during regular reconnaissance trips have been developed.

The article studies the issue of scientific and practical validity of applying ethical principles of society as regulatory factors of civil law of Ukraine. Taking into account the lack of validity of ethical principles of society as regulatory factors, the author attempts to make a correlation between the content of such principles of civil law as fairness, integrity and reasonableness, on the one hand, and ethical principles of the society, on the other hand. The author of the paper proves that it is inappropriate to apply the provisions of morality as regulatory factors for the regulation of civil relations. The conclusion on the objection to the civil regularity of ethical principles of society is based on several theses. Firstly, moral rules are not formalized, which creates a threat of arbitrary interpretation of their content. Secondly, ethical principles do not have a definite source of origin. Thirdly, the fundamental ethical rules have already been taken into account in the content of the principles of fairness, integrity and reason, which in turn create competition between the two types of regulatory factors. Unreasonable duplication of regulatory requirements reduces the functionality of the law, complicates the perception of its requirements. The competition between the principles of law and the ethical principles of society must be eliminated by refusing to give the latter the function of regulatory factors. The author of the paper does not deny the possibility of taking into account the ethical principles of society while regulating the relations that have been neglected by the "official law".

AbstractTo determine which Vedic texts Pāini knew requires a comprehensive approach that establishes a high correlation between the complete set of linguistic traits his treatise describes and the complete set of linguistic traits exhibited in each text in question. The examination of individual linguistic traits is inadequate to determine which texts he knew because neither the Vedic nor the grammatical tradition is uniform and static. Bronkhorst (Pāinian Studies: Professor S. D. Joshi Felicitation Volume, p. 75, 1991) calls into question the assumption that Vedic texts were known to Pāini in the form we have received them, while Cardona (Pāinian Studies: Professor S. D. Joshi Felicitation Volume, p. 130, 1991) shows that Pāini's silence concerning certain Vedic forms may be due to deference to certain received exegetical traditions. The current paper considers a case where the Pāinian grammatical tradition entertains disagreement over the derivation of obscure forms. Doubt concerning the recurrence of the term pit (3.4.92) into 3.4.94 brings into question whether Pāini systematically accounts for stem strengthening in the present subjunctive. Kātyāyana, Patañjali, Jayāditya, and Jinendrabuddhi remain silent on the point. Rāmacandra, Śīkria, and Bhaojidīkita assert that pit recurs, thereby allowing stem strengthening. Haradatta, on the other hand, maintains that a rule of indeterminate variation, 3.4.117 chandasy ubhayathā, accounts for it. Nāgeśa points out that the latter procedure is more comprehensive in that it accounts for the lack of stem strengthening in exceptional forms, such as Krvaíte in the Rgveda. The implication is that the former procedure fails to account for the form, which, if Pāini's knowledge of texts were to be established based upon the consideration of individual traits, would imply the absurdity that Pāini, as interpreted by Rāmacandra et al. did not know the Rgveda. On the contrary, however, the procedure of Rāmacandra et al. can employ another rule of indeterminate variation: 3.1.85 vyatyayo bahulam. This procedure, which provides a systematic explanation of the present subjunctive generally and requires a rule of indeterminate variation only to account for exceptional forms, is preferable to leaving the account of stem strengthening in the present subjunctive generally to a rule of indeterminate variatio Since both procedures rely on rules of indeterminate variation to account for the Rgvedic form, however, it is impossible to establish either Pāini's knowledge or ignorance of the text on the basis of his account of the subjunctive. The controversy demonstrates that the depth and variety of the Indian grammatical tradition must be taken into account in determining which rules describe which linguistic facts and that it is inadequate to consider individual traits. A comprehensive approach is required.

DC/AC performances of 3-nm-node gate-all-around (GAA) FETs having different widths and the number of channels (Nch) from 1 to 5 were investigated thoroughly using fully-calibrated TCAD. There are two types of GAAFETs: nanowire (NW) FETs having the same width (WNW) and thickness of the channels, and nanosheet (NS) FETs having wide width (WNS) but the fixed thickness of the channels as 5 nm. Compared to FinFETs, GAAFETs can maintain good short channel characteristics as the WNW is smaller than 9 nm but irrespective of the WNS. DC performances of the GAAFETs improve as the Nch increases but at decreasing rate because of the parasitic resistances at the source/drain epi. On the other hand, gate capacitances of the GAAFETs increase constantly as the Nch increases. Therefore, the GAAFETs have minimum RC delay at the Nch near 3. For low power applications, NWFETs outperform FinFETs and NSFETs due to their excellent short channel characteristics by 2-D structural confinement. For standard and high performance applications, NSFETs outperform FinFETs and NWFETs by showing superior DC performances arising from larger effective widths per footprint. Overall, GAAFETs are great candidates to substitute FinFETs in the 3-nm technology node for all the applications.

The problem in this paper lies in the polemic that arises in the understanding of double predestination, especially regarding the theological dilemmas in it. On the one hand, God is described as a cruel and inhuman God when only choosing some people to be saved, and on the other hand Christian doctrine recognizes that God does indeed choose some people to love. The purpose of writing this essay is to prove that a comprehensive approach can reduce theological dilemmas and conflicts when discussing the formulation of predestination. The research method used is literature study, by describing the core of Calvin's double predestination and reviewing it by involving the interrelated attributes of God. The results of this study prove that when the concept of predestination is reviewed by involving the attributes of God as a whole, it appears that God cannot be called an arrogant God when choosing humans in the project of salvation.

<p><strong>Abstract.</strong> Geospatial Information Authority of Japan (GSI) provides the “Digital Japan Basic Map” as fundamental geospatial information of Japan. Main items of the “Digital Japan Basic Map” such as major roads, large scale buildings and administrative boundaries are quickly and continuously updated as soon as useful source data are obtained from collaborating public facility administrators and local governments. On the other hand, other items are revised at relatively long interval using ortho images, urban planning base maps and other sources depending on the changes of national land throughout Japan.</p><p> Mountain trails are a part of the “Digital Japan Basic Map” as one of the road feature which should be updated quickly and continuously. When GSI provided the initial 1:25,000 scale topographic maps, which cover the whole area of national land and are one of the source of “Digital Japan Basic Map”, GSI conducted field surveys and drew mountain trails using aerial photographs. They have been updated partly so far. When landslips occur, mountain trails easily change their locations. In the thickly wooded areas, they are difficult to draw using only aerial photographs, requiring time and labour-consuming field surveys. On the other hand, the primary cause of distress in mountainous areas is getting lost. Therefore providing accurate and updated maps is essential to decrease distress and to keep mountaineers safety.</p><p> People who use mountaineering applications on their smartphones and tablets are increasing more and more, as almost all smartphones and tablets have a GNSS module and provide locations on maps. The applications users post and share the information of their walking paths, which are recorded by their smartphones and tablets, on the web sites for the community of mountaineers. The more the number of the applications users increase, the more walking paths are stored as big data on the web sites.</p><p> GSI concluded the agreements between two private companies respectively which manage the web sites for the community of mountaineers in December, 2017. Thus GSI received enormous walking paths information as big data from the cooperating companies and commenced to update mountain trails using big data. GSI provided the first updated maps using big data of walking paths in March, 2018. Now GSI continues to update trails of major mountains all over Japan. GSI will quickly and continuously provide the accurate and updated maps using big data, contributing to the safety and convenience of mountaineers.</p>

AbstractWe have developed a model for theH2OandOHevolution in a comet outburst, assuming that together with the gas, a distribution of icy grains is ejected. With an initial mass of icy grains of 108kg released, theH2OandOHproductions are increased up to a factor two, and the growth curves change drastically in the first two days. The model is applied to eruptions detected in theOHradio monitorings and fits well with the slow variations in the flux. On the other hand, several events of short duration appear, consisting of a sudden rise ofOHflux, followed by a sudden decay on the second day. These apparent short bursts are frequently found as precursors of a more durable eruption. We suggest that both of them are part of a unique eruption, and that the sudden decay is due to collisions that de-excite theOHmaser, when it reaches the Cometopause region located at 1.35 × 105kmfrom the nucleus.

Transmission Microscope

We have become accustomed to differentiating between the scanning microscope and the conventional transmission microscope according to the resolving power which the two instruments offer. The conventional microscope is capable of a point resolution of a few angstroms and line resolutions of periodic objects of about 1Å. On the other hand, the scanning microscope, in its normal form, is not ordinarily capable of a point resolution better than 100Å. Upon examining reasons for the 100Å limitation, it becomes clear that this is based more on tradition than reason, and in particular, it is a condition imposed upon the microscope by adherence to thermal sources of electrons.

Life beyond 1MeV – like life after 40 – is not too different unless one takes advantage of past experience and is receptive to new opportunities. At first glance, the returns on performing electron microscopy at voltages greater than 1MeV diminish rather rapidly as the curves which describe the well-known advantages of HVEM often tend towards saturation. However, in a country with a significant HVEM capability, a good case can be made for investing in instruments with a range of maximum accelerating voltages. In this regard, the 1.5MeV KRATOS HVEM being installed in Berkeley will complement the other 650KeV, 1MeV, and 1.2MeV instruments currently operating in the U.S. One other consideration suggests that 1.5MeV is an optimum voltage machine – Its additional advantages may be purchased for not much more than a 1MeV instrument. On the other hand, the 3MeV HVEM's which seem to be operated at 2MeV maximum, are much more expensive.

Summary: My comment is basically restricted to the situation in which less-able students find themselves and refers only to literature in German. From this point of view I am basically able to confirm Marsh's results. It must, however, be said that with less-able pupils the opposite effect can be found: Levels of self-esteem in these pupils are raised, at least temporarily, by separate instruction, academic performance however drops; combined instruction, on the other hand, leads to improved academic performance, while levels of self-esteem drop. Apparently, the positive self-image of less-able pupils who receive separate instruction does not bring about the potential enhancement of academic performance one might expect from high-ability pupils receiving separate instruction. To resolve the dilemma, it is proposed that individual progress in learning be accentuated, and that comparisons with others be dispensed with. This fosters a self-image that can in equal measure be realistic and optimistic.

Abstract. Two experiments examined the influence of stories on recipients’ self-perceptions. Extending prior theory and research, our focus was on assimilation effects (i.e., changes in self-perception in line with a protagonist’s traits) as well as on contrast effects (i.e., changes in self-perception in contrast to a protagonist’s traits). In Experiment 1 ( N = 113), implicit and explicit conscientiousness were assessed after participants read a story about either a diligent or a negligent student. Moderation analyses showed that highly transported participants and participants with lower counterarguing scores assimilate the depicted traits of a story protagonist, as indicated by explicit, self-reported conscientiousness ratings. Participants, who were more critical toward a story (i.e., higher counterarguing) and with a lower degree of transportation, showed contrast effects. In Experiment 2 ( N = 103), we manipulated transportation and counterarguing, but we could not identify an effect on participants’ self-ascribed level of conscientiousness. A mini meta-analysis across both experiments revealed significant positive overall associations between transportation and counterarguing on the one hand and story-consistent self-reported conscientiousness on the other hand.
