Records of interesting flies (Diptera) attracted to meat baited pyramidal trap on sapping stump of European walnut (Juglans regia) in Central Bohemia (Czech Republic) A pyramidal trap with combined bait is described and illustrated. The trap inserted above sapping stump of European walnut (Juglans regia) in a site in Central Bohemia near Uhlířské Janovice in 2010 yielded a rich spectrum of flies (Diptera). Records of 24 species most interesting from the faunistic, biological and nature conservancy point of view are given with comments upon their distribution and biology but a number of other captured species are also mentioned. Besides species developing in or attracted as adults to sap runs [e.g. Syrphidae: Ceriana conopsoides (Linnaeus, 1758), Aulacigastridae: three Aulacigaster spp., various Drosophilidae], other important components were formed by saproxylic [Xylomyidae: Solva marginata (Meigen, 1820), some Stratiomyidae, many Lonchaeidae, Milichiidae: Milichia ludens (Wahlberg, 1847), some Muscidae], mycophagous (some Asteiidae, Sphaeroceridae, Drosophilidae), necrophagous (some Sepsidae, Acartophtalmidae, Milichiidae, Sphaeroceridae) and saprophagous (some Sepsidae, Carnidae, Milichiidae, Sphaeroceridae) species, both latter attracted to meat-bait used in the trap. Aulacigaster falcata Papp, 1998 is the first record from Bohemia.

We study a one-parameter class of examples of optimal transport problems between a two-dimensional source and a one-dimensional target. Our earlier work identified a nestedness condition on the surplus function and marginals, under which it is possible to solve the problem semi-explicitly. In the family of examples we consider, we classify the values of parameters which lead to nestedness. In those cases, we derive an almost explicit characterisation of the solution.

No statute defines indecency, yet this is the element that makes the difference between common assault (a summary offence, maximum six months) and indecent assault (maximum now ten years). In gross cases no question arises; the trouble is with the marginals. The courts solve them, as they solve so many problems on jury trial, by leaving the question of indecency pretty well at large to the jury. This long-established rule was reaffirmed by the lords in Court. Lord Ackner, with the concurrence on this point of all the other lords, said ‘The prosecution must prove & that the assault, or the assault and the circumstances accompanying it, are capable of being considered by right-minded persons as indecent’.

Rosario, en su expansión de finales del siglo XIX, generó espacios que permanecieron como relictos hasta hoy. Las poblaciones residentes eran marginadas, a la espera del trabajo o de la basura que les permitía sobrevivir: la prensa de la época solía ser sarcástica con respecto a estos grupos, considerados un obstáculo para la civilización.
 Una de estas crónicas posibilitó acercarse a uno de esos lugares “insalubres”: el Baño de Mandinga. Articulando historia y arqueología, el objetivo de este trabajo fue iniciar una serie de estudios sobre las poblaciones que la historia de Rosario por lo general ha ignorado.

"Action research for the conservation of architectural heritage in mariginal areas: the role of evaluation / La ricerca azione per la conservazione del patrimonio architettonico in aree marginali: il ruolo della valutazione." Valori e Valutazioni 30 (August 2022): 3–44. http://dx.doi.org/10.48264/vvsiev-20223002.
Full textAbstract:
The recognition of the key role of architectural heritage for sustainable territorial development has pushed the scientific community to give more importance to the involvement of local communities in conservation choices and practices. However, despite the recognition of the benefits deriving from the active participation of local communities in the field of conservation, in practice, this involvement is still marginal and linked to experiences without institutional support. This phenomenon is due to different causes, such as the lack of a participatory culture in conservation. It finds its roots in a conventional approach to architectural heritage conservation merely based on an “expert knowledge”. Consequently, there is an urgent need for approaches and tools to manage the complexity of decisions about conservation, which require close collaboration between local communities, research, and institutions. In this context, the paper aims to investigate the role of the action-research approach in fostering the participation of local communities in conservation processes, especially in marginal areas, where the demographic shrinking dynamics make even more necessary both the institutions’ intervention and the communities’ engagement. Based on these premises, starting from an analysis of recent experiences, the contribution dwells on the need to support the implementation of action-research approaches for the conservation of architectural heritage in marginal areas, paying particular attention to the role of evaluation. More in detail, in the first part of the paper, a reflection on the importance of community involvement for heritage conservation is proposed based on the main documents on the topic. In the second part, the main features of the action-research approach and its strengths and weaknesses have been analyzed through a literature review of action-research experiences applied to architectural heritage at a global level. The analyses have highlighted how most of these experiences are born from spontaneous initiatives, without institutional and methodological support, in which the role of evaluation is still marginal. Therefore, in the final part, the paper proposes a first methodological framework based on integrating action research with the main evaluation tools developed in the scientific literature to support the different phases of the decision-making process. This framework, suitably declined according to the specificities of the case study treated, can represent a valid support for implementing and transposing the research-action approach for heritage conservation in an institutional context. Il riconoscimento del ruolo chiave del patrimonio architettonico per uno sviluppo territoriale sostenibile ha spinto la comunità scientifica ad attribuire maggiore importanza al coinvolgimento delle comunità locali nelle scelte e pratiche di conservazione. Tuttavia, nonostante il riconoscimento dei benefici derivanti dalla partecipazione attiva delle comunità locali in ambito conservativo, nella pratica tale coinvolgimento risulta ancora marginale e legato ad esperienze prive di supporto istituzionale. Tale fenomeno è ascrivibile a molteplici cause, tra cui la mancanza di una cultura della partecipazione, che affonda le sue radici nell’approccio convenzionale alla conservazione del patrimonio architettonico basato sulla sola “conoscenza esperta”, e la conseguente carenza di approcci e strumenti capaci di gestire la complessità delle scelte legate alla conservazione in cui, invece, si richiede una stretta collaborazione tra comunità locali, mondo della ricerca e istituzioni. Il presente contributo mira ad indagare il ruolo dell’approccio della ricerca azione nel favorire la partecipazione delle comunità locali ai processi di conservazione soprattutto nelle aree marginali, dove le dinamiche di contra- zione demografica in atto rendono ancora più necessario sia l’intervento delle istituzioni, che la partecipazione delle comunità. Sulla scorta di tali premesse, partendo da un’analisi delle esperienze in corso, il contributo si sofferma sulla necessità di supportare l’implementazione di approcci alla ricerca-azione per la conservazione del patrimonio architettonico in aree marginali, ponendo parti- colare attenzione al ruolo della valutazione per il raggiungimento di tale obiettivo. Nello specifico, nella prima parte del contributo si propone una riflessione sull’importanza del coinvolgimento delle comunità per la conservazione del patrimonio sulla base delle principali carte e trattati sul tema. Nella seconda parte sono state, poi, analizzate le principali caratteristiche dell’approccio alla ricerca-azione ed i suoi punti di forze e di debolezza rispetto alle finalità preposte attraverso una literature review delle esperienze di ricerca azione applicate al patrimonio architettonico a livello globale. Le analisi condotte hanno portato ad evidenziare come la maggior parte delle esperienze analizzate nasca da iniziative spontanee, prive di un supporto istituzionale e metodologico, in cui il ruolo della valutazione è ancora marginale. Pertanto, nella parte finale della riflessione si propone una prima proposta di framework metodologico basato sul- l’integrazione della ricerca azione con i principali strumenti di valutazione sviluppati in letteratura al fine di supportare le differenti fasi del processo decisionale. Tale framework, opportunamente declinato secondo le specificità del caso studio trattato, può rappresentare un valido supporto per l’implementazione e la trasposizione in ambito istituzionale dell’approccio alla ricerca-azione per la conservazione del patrimonio.

Full textAbstract:
In this letter, we examine a general method of approximation, known as the Kikuchi approximation method, for finding the marginals of a product distribution, as well as the corresponding partition function. The Kikuchi approximation method defines a certain constrained optimization problem, called the Kikuchi problem, and treats its stationary points as approximations to the desired marginals. We show how to associate a graph to any Kikuchi problem and describe a class of local message-passing algorithms along the edges of any such graph, which attempt to find the solutions to the problem. Implementation of these algorithms on graphs with fewer edges requires fewer operations in each iteration. We therefore characterize minimal graphs for a Kikuchi problem, which are those with the minimum number of edges. We show with empirical results that these simpler algorithms often offer significant savings in computational complexity, without suffering a loss in the convergence rate. We give conditions for the convexity of a given Kikuchi problem and the exactness of the approximations in terms of the loops of the minimal graph. More precisely, we show that if the minimal graph is cycle free, then the Kikuchi approximation method is exact, and the converse is also true generically. Together with the fact that in the cycle-free case, the iterative algorithms are equivalent to the well-known belief propagation algorithm, our results imply that, generically, the Kikuchi approximation method can be exact if and only if traditional junction tree methods could also solve the problem exactly.

Previous issue date: 2005-03-24<br>The adaptation precision of metallic structures to implant abutments is a very questionable subject and the scientific literature lacks about the alloy that shows an adaptation closer to the ideal. This study had the proposal of: evaluating the vertical marginal misfit levels (in μm) using a digital microscope of one-piece
and after laser welding metallic structures of total fixed implant supported prosthesis casted in Nickel-Chrome, Nickel-Chrome-Titanium-Molibidenium and Palladium-Silver alloys and commercially pure Titanium, over two different kinds of abutments and, also, associate the misfit results observed at the one-piece structures phase with the data obtained after the laser welding treatment. After the fabrication of two master models, 40 pre-fabricated copings for both Estheticone and Micro-Unit type abutments were used at the survey. Eight metallic structures were casted with Ni-Cr, Ni-Cr-Ti-Mo, Pd-Ag and Ti-c.p., being two structures for each alloy. The vertical misfit values concerning the relation of the metallic
structures and implant abutments from all alloys and on both stages one-piece and after laser welding were tabulated and then submitted to statistical tests. The
values were exposed to the ANOVA and the significant statistic means were compared by the Tukey test considering a 5% significance value (p<0.05), as well
as the standard deviation. The results evidenced that the one-piece structures showed misfit, but the mean values did not present statistic significant differences.
The material (alloys) analysis showed that the Ti-c.p. did not show discrepant mean values, but the same did not occur with the other alloys. The comparison between all alloys showed no significant statistical differences, and, the Pd-Ag alloy (control group) showed the higher misfit mean values at the one-piece phase. The relation between the one-piece and after laser welding phases showed the presence of statistic significant values, based on the mean values (onepiece= 0.0953 μm / laser welding=0.0452 μm) and the marginal vertical misfit after laser welding appeared significantly decreased.<br>A precisão da adaptação das infra-estruturas sobre pilares de implantes é objeto de inúmeros questionamentos e a literatura ainda é carente em relação à liga que possa apresentar adaptação próxima do ideal. Assim, esta pesquisa teve
como propósitos: avaliar os níveis de desajustes marginais verticais (em μm) por meio de microscópio mensurador digital das infra-estruturas metálicas em monobloco e após soldagem a laser de próteses totais fixas fundidas em ligas de Níquel-Cromo, Níquel-Cromo-Titânio-Molibidênio, Paládio-Prata e Titânio Comercialmente Puro assentadas sobre dois tipos diferentes de pilares de implantes e, ainda, correlacionar os resultados obtidos dos níveis de desajustes das infra-estruturas monobloco com os das infra-estruturas pós-soldagem (a laser). A partir de dois modelos-mestre, foram enceradas 40 amostras sobre copings pré-fabricados de pilares de implantes tipo Estheticone e Micro-Unit (Conexão Sistema de Prótese-SP). Obteve-se oito infra-estruturas metálicas a partir da fundição das ligas Ni-Cr, Ni-Cr-Ti-Mo, Pd-Ag e Ti-c.p., sendo duas infraestruturas para cada liga. Os valores correspondentes às leituras das distâncias verticais (em !m) da relação infra-estruturas metálicas e pilares de implantes de todas as amostras das diferentes ligas metálicas utilizadas e das etapas monobloco e soldagem a laser foram tabulados e, em seguida, aplicado os testes estatísticos. Os valores foram sujeitos à análise de variância e as médias com diferenças estatísticas significativas foram comparadas pelo teste de Tukey com nível de significância 5% (p<0,05), bem como o desvio padrão. Os resultados
evidenciaram que nas infra-estruturas em monobloco (sem solda), houve a presença de desajuste, porém os valores médios não apresentaram diferenças estatísticas significativas. Na avaliação do material empregado (ligas) verificou-se que as infra-estruturas em Ti-c.p. não apresentaram valores médios discrepantes, o que não ocorreu com as infra-estruturas obtidas com as demais ligas. Na
comparação de todas as ligas utilizadas, os seus valores médios não apresentaram diferenças estatísticas significativas e a liga de Pd-Ag (Grupo Controle) foi a que apresentou valor médio de maior desajuste nas estruturas em monobloco. Na correlação das infra-estruturas monobloco e pós-soldagem (a
laser), evidenciou-se a existência de diferenças estatísticas significativas, baseado nos valores médios (monobloco 0,0953μm / solda a laser 0,0452μm), sendo o desajuste marginal vertical para a infra-estrutura com solda a laser,
significativamente menor.

This chapter suggests that notions of real interest to mathematicians are not on the printed page but lurk behind the doors of conception. It is believed that they will someday emerge and shed so much light on earlier concepts that the latter will disintegrate into marginalia. By their very nature, they elude precise definition, so that on the conventional account they are scarcely mathematical at all. Coming to grips with them is not to be compared with attempting to solve an intractable problem. Instead, it harbors a more fundamental obscurity. One cannot even formulate a problem, much less attempt to solve it; the items (notions, concepts) in terms of which the problem would be formulated have yet to be invented. How then can we talk to one another, or to ourselves, about the mathematics we were born too soon to understand?

This article analyzes a complex of archival documents and materials, legislative acts and regulations, as well as statistical data on the employment of the Jewish population in the alcohol industry. It considers the scale, degree, and form of Jewish involvement in the industry in the Russian Empire during the second half of the nineteenth and early twentieth centuries in general and the Taurida province in particular. In order to identify “the moral and economic activities of the Jews, which adversely affect the life of the indigenous population,” provincial commissions on the “Jewish question” in Russia provided the government with proposals to solve “the problem.” This article explores two things: the legal measures that were introduced to regulate the alcohol trade; and the public sentiments which directed against this marginal part of Jewish society, which led to transformations in the social structure of the Jewish community and the strengthening of antisemitism in Russian society. Through archival documents — some of which are made available to scholars for the first time — details about Jews engaged in drinking and prostitution in the Taurida province are revealed.

Farmers own and run Farmer Producer Companies (FPCs), a rapidly growing companies in India that was established under the section 465(1) of the Companies Act, 2013. Agriculture continues to be the backbone of the Indian economy, employing 42% of the labour force and contributing 20% of the country’s GDP. 86.6% of India’s small and marginal farmers depend on farming as their main source of income. Small and marginal farmers, in particular, play a significant role as shareholders in FPCs, which bring people together from all walks of life to learn more about the issue’s existence at the local level and help solve it. The FPC is the best institutional structure for addressing a range of agricultural issues, including marketing, financing (forward linkages), input, technology (backward linkages), compact technology for small lands, proper marketing linkage, capacity building, training program on value-added products, financial inclusion program, village storage facilities, timely crop insurance, agriculture extension services, and the benefits of informatics. In order to increase income and subsequently promote more equitable growth, the study investigates how FPC addresses local food and nutrition security, the development of climate-resilient agriculture systems, input shortages, unemployment, and the integration of small and marginal farmers into agricultural markets.

In this paper we formulate a novel Divide-and-Coordinate (DaC) algorithm, the so-called Egalitarian Utilities Divide-and-Coordinate (EU-DaC) algorithm. The Divide-and-Coordinate (DaC) framework [3] is a family of bounded DCOP algorithms that solve DCOPs by exploiting the concept of agreement. The intuition behind EU-DaC is that agents get closer to an agreement, on the optimal solution, when they communicate the local max-marginals utilities for their assignments instead of only their preferred assignments. We provide empirical evidence supporting this hypothesis as well as illustrating the competitiveness of EU-DaC.

Full textAbstract:
Threat Screening Games (TSGs) are used in domains where there is a set of individuals or objects to screen with a limited amount of screening resources available to screen them. TSGs are broadly applicable to domains like airport passenger screening, stadium screening, cargo container screening, etc. Previous work on TSGs focused only on the Bayesian zero-sum case and provided the MGA algorithm to solve these games. In this paper, we solve Bayesian general-sum TSGs which we prove are NP-hard even when exploiting a compact marginal representation. We also present an algorithm based upon a adversary type hierarchical tree decomposition and an efficient branch-and-bound search to solve Bayesian generalsum TSGs. With this we provide four contributions: (1) GATE, the first algorithm for solving Bayesian general-sum TSGs, which uses hierarchical type trees and a novel branch-and-bound search, (2) the Branch-and-Guide approach which combines branch-and-bound search with the MGA algorithm for the first time, (3) heuristics based on properties of TSGs for accelerated computation of GATE, and (4) experimental results showing the scalability of GATE needed for real-world domains.

In this chapter, we introduce some basic concepts of mathematics, which are preliminaries, in particular, some properties of integer numbers. After having a short marginal discussion about reasoning, we introduce some methods of reasoning, including the induction method, and present some results with this method. When we consider the outcomes of several experiments, we shall follow two basic counting techniques, namely sum and product rules that can be used to solve some types of problems in applications of counting. Using these rules, we introduce combinatorics, which is a branch of mathematics devoted to calculating the number of ways in which a specified process can be carried out.

The ever-rising demand for computing services and the humongous amount of data generated everyday has led to the mushrooming of power craving data centers across the globe. These large-scale data centers consume huge amount of power and emit considerable amount of CO2.There have been significant work towards reducing energy consumption and carbon footprints using several heuristics for dynamic virtual machine consolidation problem. Here we have tried to solve this problem a bit differently by making use of utility functions, which are widely used in economic modeling for representing user preferences. Our approach also uses Meta heuristic genetic algorithm and the fitness is evaluated with the utility function to consolidate virtual machine migration within cloud environment. The initial results as compared with existing state of art shows marginal but significant improvement in energy consumption as well as overall SLA violations.

Full textAbstract:
Abstract A seachest is a void space or box on the body of a marine vessel below the water line from which piping systems draw raw water for cooling or other uses such as ballasting of the vessel and fire-fighting. The inlet grid or intake of the seachest, which is protected by a grating, can vary in size from under 1 sq. meter for a small inland tug to several hundred sq. meters for a large vessel like an oil tanker. The seachest is normally fabricated from carbon steel like the rest of the vessel, while the adjoining piping and valves are nonferrous. Zinc anodes in combination with coatings are used for the corrosion protection of the ship’s hull as well as the seachest. A waster-sleeve, typically fabricated from 0.375-inch (9.52 mm) thick carbon steel plate, is recommended as additional sacrificial protection for the non-ferrous components with a projected service life of 10-12 years or more. Since the waster sleeves (as well as adjoining non-ferrous components) are electrically continuous to each other, they also receive some protection from the zinc anodes. Replacement of waster-sleeves is a high cost item. Depending on the size of the waster-sleeves, dry-dock replacement installation can cost anywhere from $5,000 to $25,000 while underwater installations can be as much as $200,000. Hence, early failure of these and other seachest components can seriously impact the extended life cycle goals for these vessels. During the nineties, premature failure of waster-sleeves were observed on a number of ocean-going vessels. Based on shipyard surveys of failed waster sleeves it was found that the standard thickness of 0.375 in (9.52 mm) was not sufficient to survive the desired 12-year service life and even doubling the thickness only had marginal effect. Engineering analysis indicated that the existing CP design utilizing only 2 to 4 pieces of 42-lb (19.1 Kg) Zn anodes was inadequate and a re-designed CP system with a larger number of anodes would possibly solve the problem.

Durante esta investigación se analiza comparativamente el proceso de formación y gestión llevado a cabo
 para la implementación de dos programas de vivienda social; el programa de realojamiento de población
 marginada - Barrios de tipología especial- implementado en Madrid, España (1986) y el programa nuevos
 barrios – “Mi casa mi vida” en Córdoba, Argentina (2001). Ambos programas fueron ejecutados para
 resolver la problemática habitacional de grupos marginales, a través del traslado y realojo a nuevos barrios
 construidos especialmente para estos sectores. Se procura estudiar el proceso de formulación e
 implementación de dichos programas, intentando descubrir si era posible predecir desde la formulación de
 dichos programas las problemáticas actuales de exclusión urbana como un agravante a las problemáticas
 de exclusión social. Será objeto de este artículo reflexionar sobre la capacidad del estado para incidir en los
 modos de hacer ciudad incorporando o no las necesidades de integración socio-urbanas de las poblaciones
 afectadas. During this research are analyzed and compared the structure and management process carried out for the implementation of two social housing programs, the re-housing program for marginal population- Suburbs of 
 special typology (BTE)– in Madrid - Spain (1986) and new neighborhoods program –“My house my life”- in Córdoba Argentina (2001). Both programs were made to solve the housing problems of marginalized groups, 
 through relocation and re-housing of the affected people to new neighborhoods built especially for them. The purpose of this comparative analysis is to study the process of design and implementation of the two housing programs, trying to find out if it was possible to predict from the formulation of such programs, issues of urban 
 exclusion as an aggravating factor of the social exclusion. The object of this article will reflect the state’s ability to influence in urban development, incorporated or not social-urban integration needs of the affected populations.

Poisson Trivariate Gumbel Extreme Value Distribution (PTGEVD), a multivariate from of the Compound Extreme Value Distribution, is presented to solve for the ocean environmental design criteria in this paper. The proposed model is combined with a discrete distribution of storm frequency and a continuous trivariate extreme value distribution of environmental conditions simultaneously occurred in storm processes. Different from traditional univariate design method, the proposed design method with PTGEVD can reflect the combined effect of multi-loads on offshore structures and result in reasonable reduction of the design criteria. Validated with the synchronically measured significant wave heights, wind speeds and current velocities of 20 typhoon processes, PTGEVD model shows that it is easy to be applied and has considerable economic potential in the exploitation of ocean oil and gas, especially for marginal field.

Full textAbstract:
Abstract Expensive drilling is highly impacting the overall marginal field profitability due to the low reserves and short well life. In this paper, we considered the case of a marginal field with multiple reservoirs stacked above each other with a thin dense layer between each pair of reservoirs. The initial plan was to drill a single horizontal oil producer well across each of reservoirs. Those wells had planned to equip Electric Submersible Pump (ESP) completions to ensure enough surface pressure to pump the produced fluids to the gathering facility, which is far from the well's surface location, in addition to an expected increase in water production in the early stages of well production. To reduce the overall project cost and to overcome all those challenges, collaborative work resulted in agreement on drilling one well with two lateral horizontal holes across two different reservoirs instead of drilling two single wells, which conflicted with regulations that prevent comingled production through a single completion. To solve regulation of comingled production, a simple smart lower completion with Inflow Control Device-Sliding Sleeve Doors (ICD-SSD's) and swell packers was used to control production from both reservoirs whenever required, in addition to using a single ESP completion to produce from both zones together. This well design helped to reduce the total drilling cost by USD 5 million while achieving the same production rate that was expected from the two individual wells that were originally planned to produce from the two different reservoirs.

Full textAbstract:
Two-phase flow instability and dynamics of a parallel multichannel system has been theoretically studied under periodic excitation induced by rolling motion in the present research. Based on the homogeneous flow model considering the rolling motion, the parallel multichannel model and system control equations are established by using the control volume integrating method. Gear method is used to solve the system control equations. The influences of the inlet, upward sections, and heating power on the flow instability under rolling motion have been analyzed. The marginal stability boundary (MSB) under rolling motion condition is obtained. The unstable regions occur in both low and high equilibrium quality and inlet subcooling regions. The multiplied period phenomenon occurs in the high equilibrium quality region and the chaos phenomenon appears on the right of MSB. The concept of stability space is presented.

Full textAbstract:
In this paper we put forward a novel extension of the classic Max-Sum algorithm to the framework of Continuous Distributed Constrained Optimization Problems (Continuous DCOPs), by utilizing a popular geometric algorithm, namely Quadtrees. In its standard form, Max-Sum can only solve Continuous DCOPs with an a priori discretization procedure. Existing Max-Sum extensions to continuous multiagent coordination domains require additional assumptions regarding the form of the factors, such as access to the gradient, or the ability to model them as continuous piecewise linear functions. Our proposed approach has no such requirements: we model the exchanged messages with Quadtrees, and, as such, the discretization procedure is dynamic and embedded in the internal Max-Sum operations (addition and marginal maximization). We apply Max-Sum with Quadtrees to lane-free autonomous driving. Our experimental evaluation showcases the effectiveness of our approach in this challenging coordination domain.

Full textAbstract:
Willow (Salix) family is one of the fastest-growing woody energy crops. It·has been widely used for biomass energy production in short-rotation plantations, carbon storage in longer rotation, and as a phytoremediation plant in Northern Europe. Willows could be cultivated on a wide range of soils, including marginal land, and they are readily propagated by planting un-rooted cuttings. Soil fertilization is necessary for obtaining a higher biomass yield. Different side products of energy production and municipal waste could be used for soil improvement. The aim of this research is to review fertilization practices in short-rotation willow plantations and their impact on the biomass yield. The data from the literature were collected, and different doses of various fertilizers were compared. The response to fertilization is positive if fertilizer contains complex NPK macro elements. The most appropriate dose per hectare varies depending on the soil properties, soil types, willow varieties, weather conditions, water availability, and other factors. Wood ash and peat could be used for soil improvement to solve the main characteristic marginal soils problems in Latvia – low organic content and pH value. Wood ash has high concentrations of calcium (Ca) and magnesium (Mg) and already is widely used as a liming agent in organic farming. Less demanded peat fractions, dewatered wastewater sludge, and biogas fermentation leftover -digestate contain a high amount of organic matter and nitrogen, therefore, could be used as a replacement for previously used fertilizers such as cattle slurry. In addition, wastewater sludge, digestate, and wood ash are also sources of microelements. A mix of all listed products has a high potential to be used as a complex soil amendment.

Full textAbstract:
Abstract During the wafer-sort stage, critical electrical data on the IC chip performance is collected. As technology advances, smaller geometries are continuously implemented to the production line and, as a result, there may be some issues that are difficult to detect and eliminate at the typical wafer-sort or final-test techniques. This paper presents two successful applications of innovative wafer-sort techniques to solve some difficult issues. In the first case, voltage-stress is implemented in the wafer-sort to draw out yield issues which otherwise go undetected. This additional test component helps to screen-out marginal dies and analyze the post-stress spatial pattern. By applying the MERCAD detection system to localize the fault area and the appropriate delayer techniques, metal microbridge is found. In the second case, wafer-sort collects the testing information for the failing scan chains. This information is mapped to the netlist, schematic, and design layout of the chip. Given this information, together with the design layout, the authors are able to narrow down these issues to some metal pattern defects.

The marginal stability boundary (MSB) under rolling motion condition is obtained and the unstable regions occur in both low and high equilibrium quality regions. The region with low inlet subcooling is also instable. In high equilibrium quality region, the multiplied period phenomenon is found and the chaotic phenomenon appears at the MSB. The oscillation part of mass flow rate (amplitude) may be averaged into other channels so that the influence of rolling motion is weakened. But the stability of multi-channel system is independent of the channel number and the increase of the channel number could only make the amplitude more uniformity in channels.

Full textAbstract:
No atual cenário competitivo das organizações, a qualidade final de seus produtos são essenciais para se manter no mercado, entretanto, muitas variabilidades podem afetar os processos de modo a alterar a qualidade do produto. Considerando um processo de soldagem de revestimento, monitorar a qualidade final da solda é de suma importância, entretanto, a medição manual pode não ser suficientemente precisa dada as diversas geometrias irregulares do processo.Nesse ínterim, ao usar a Análise do Sistema de Medição (ASM), é possível determinar quantitativamente a variabilidade do sistema e a adequabilidade do sistema de medição. Este trabalho apresenta um estudo comparativo entre o método da ANOVA e X&R para análise da repetitividade e reprodutibilidade das principais características da qualidade de um cordão de solda de revestimento em chapas de aço ABNT 1020. Foram utilizados 62 medições de 31 peças, 4 operadores, 3 réplicas e 5 características geométricas do cordão de solda. No que tange os principais resultados quando há muita variabilidade, como foi o caso da altura de penetração e altura do reforço do cordão, o método da Média e Amplitude (X&R) se mostra ineficiente pois diminui o numero de categorias distintas (NDC) do processo, perdendo a sensibilidade da análise, tornando o processo marginal e precisando de um profissional da linha de produção para validar as amostras. Conclui-se então que para análise do sistema de medição de um processo de soldagem de revestimento de chapas ABNT 1020, a escolha do método de análise vai depender da experiência do responsável pela análise e da variabilidade do sistema, se o sistema apresentar alta variabilidade ambos métodos devem ser empregados e cada característica analisada individualmente, se o sistema apresentar baixa variabilidade o método X&R é melhor pois é mais simples de analisar e exige menor capacidade técnica para compreender os resultados.

Full textAbstract:
This paper studies the optimal design of assisted reproductive technologies (ART) policies in an economy where individuals differ in their reproductive capacity (or fecundity) and in their wage. We find that the optimal ART policy varies with the postulated social welfare criterion. Utilitarianism redistributes only between individuals with unequal fecundity and wages but not between parents and childless individuals. To the opposite, ex post egalitarianism (which gives absolute priority to the worst-off in realized terms) redistributes from individuals with children toward those without children, and from individuals with high fecundity toward those with low fecundity, so as to compensate for both the monetary cost of ART and for the disutility from involuntary childlessness resulting from unsuccessful ART investments. Under asymmetric information and in order to solve for the incentive problem, utilitarianism recommends also to either tax or subsidize ART investments of low-fecundity-low productivity individuals depending on the degree of complementarity between fecundity and ART in the fertility technology. On the opposite, ex post egalitarianism always recommends marginal taxation.
