Resumen

The objective of this study was to evaluate the usage of species with coloured roots to study root growth patterns during intercropping. Red beet (Beta vulgaris L. cv. Detroit), having clear red roots, was used in a semi-field and field experiment to allow identification and quantification of roots of the individual species in the mixture. In the field experiment, red beet was strip intercropped with lucerne (Medicago sativa L. cv. Creno) and kale (Brassica oleracea L. var. Sabellica), respectively while the red beet-lucerne intercropping was conducted in large rhizoboxes where root growth distribution and 15N isotope uptake was determined. The study confirmed that the direct visual measurement of root growth using species with coloured roots and indirect tracer uptake measurements contributed to the success of studying root growth dynamics in intercropping systems. Red beet root intensity was not considerably affected by the strip intercropping when the crops were established at the same time, but when established between existing lucerne strips, a reduction in roots at the border row was shown. Lucerne and kale were both observed to be able to exploit the deep soil layers beneath the red beet border row.

Resumen

Taro (Colocasia esculenta) is a root crop that remains largely underutilized and undervalued despite its abundance and affordability. In comparison to other root vegetables, such as potatoes, yams, carrots, and cassava, taro stands out as a plentiful and low-cost option. As global hunger increases, particularly in Africa, it becomes essential to address food insecurity by maximizing the potential of existing food resources, including taro, and developing improved food products derived from it. Taro possesses a wealth of carbohydrates, dietary fiber, vitamins, and minerals, thereby making it a valuable nutritional source. Additionally, while not a significant protein source, taro exhibits higher protein content than many other root crops. Consequently, utilizing taro to create food products, such as plant-based milk alternatives, frozen desserts, and yogurt substitutes, could play a crucial role in raising awareness and increasing taro production. Unfortunately, taro has been stigmatized in various cultures, which has led to its neglect as a food crop. Therefore, this review aims to highlight the substantial potential of taro as an economical source of dietary energy by exploring the rich fiber, potassium, vitamin C, protein, and other micronutrient content of taro, and providing a foundation for the formulation of novel food products. Furthermore, this paper assesses the nutritional benefits of taro, its current utilization, and its antinutritional properties. It emphasizes the need for further research to explore the various applications of taro and improve on-farm processing conditions for industrial purposes.

Resumen

Israel is the contested homeland of both the Jewish-Israeli and the Arab-Palestinian peoples. In the practice of tourism, Israel highlights sites of Jewish history and tends to neglect those of Palestinian history. Many of the Palestinian villages and heritage sites were destroyed by Israel in 1948 and onwards, or were gradually dilapidated due to lack of official care. Large-scale Palestinian roots tourism does not exist, due to the impossibility of most Palestinians to gain access into Israel. This paper explores an unusual form of roots tourism: the encounter between Jewish-Israelis and Palestinian depopulated villages that are located today within the boundaries of Israeli tourist sites. The paper demonstrates that the villages are largely ignored or marginalized in the information given to the public. The tourism authorities therefore underestimate the roots of the Palestinians in the country and portray an overall picture of a Jewish country, with very minor Arab heritage.

Resumen

Created in the image and likeness of God, man has as his ultimate reference the divine model, being called by his very nature to reflect the character and attributes of his Creator. Man as “imago Dei” is called to “imitatio Dei”. His call to holiness is at the same time a call to imitate God, a call to become like God. Even if in his transcendence God remains unknowable by his being, man can know him by the way God reveals himself through his works in the world. Imitation of God therefore enables man to move beyond speculative, abstract knowledge to a true form of knowledge which presupposes a recognition of God from His works in the world.

Resumen

The study explores the concept of discipleship in the Old Testament, highlighting how divine revelation continues to be a pedagogical and therapeutic process. At the centre of this process is the relationship between God and man, beginning with Adam and continuing with the patriarchs, prophets, and the people of Israel, culminating in the Christ disciple’s model. It is emphasised that the whole of revelation provides a complete model for discipleship, to guide humanity towards divine communion. The study also analyses the educational structures in Jewish society, in which the family, the royal court and scribal schools play essential roles. It discusses the biblical terminology specific to discipleship and the relationship between learning and the divine will, concluding that true religious education is about accumulating knowledge and living by God's will so that man can re-enter into a relationship with the supreme Teacher.

Resumen

From the Old Testament perspective, wisdom is not man's ultimate destination, but it is the way “by which” we can reach God. Travelling through life with wisdom, man finds his true theological destination by dwelling in the mystery of the revealed word. Thus, “Wisdom has built her house” (Prv 9:1), living spiritually in people who discover in the mystery of the spoken word the redemptive work of Christ in the intimacy of humanity that he came to redeem from sin. This interiority, understood as the dwelling of the Word of God in the human heart, in its spiritual abode, is interpreted by Holy Scripture, patristic and philocalic literature, as well as by the liturgical prayer of the Church as an incarnation of the Word in us, which we understand it as a food of doxological words and the communion of Eucharistic Christ, Divine Body and Blood, Liturgy of God with us in the Church of His Glory, which is His ecclesial Body.

Resumen

The main purpose of the Book of Tobit is to promote faithfulness to the Law and authentic family values. Although it is a narrative, its purpose is educational, and it can thus be perceived as part of a long tradition of academic literature. The same can be said of a much later text, from a different cultural context: The Teachings of Neagoe Basarab to His Son Theodosius. Tob 4 contains a section of direct teaching within the Book of Tobit. In the present paper, I will compare it with the second part of The Teachings. Special emphasis is given to Tob 4:3-4 which presents Tobias' filial duties towards Anna, his mother. Based on my comparison, the fathers in both works, Tobit and Neagoe Basarab, demonstrate diligence by being committed to their roles and responsibilities as fathers, urging their sons Tobias and Theodosius to remain faithful to ancestral traditions.

Resumen

The ability of plant roots to penetrate soils is affected by several stimuli from the surrounding medium such as mechanical stresses and chemical changes. Therefore, roots have developed multiple responses to the several outer stimuli. Since plant roots have to face very complex problems to grow deeply into the ground, they are remarkable examples of problem-solving behaviour and adaptation to the outer constraints. The adaptation strategies of a natural root are not yet completely known and understood with exhaustive explanations. For this reason, mathematical models and experimental techniques applied to biological phenomena can perform a key role in translating the Nature adaptive solutions into engineering applications. The aim of this thesis is to provide further insights in understanding biological phenomena for the development of new technologies inspired by the adaptive ability of plant roots. Accordingly, both theoretical and experimental explanations to the adaptive behaviour of plant roots are proposed. The mathematical modelling is based on a modified version of the extended West, Brown and Enquist universal law, considering the root growth as an inclusion problem. The proposed equation has as a particular case a growth equation exploiting an approach similar to Lockhart taking into account the soil impedance. The influence of mechanical stresses and nutrient availability on the root growth are studied. The solutions of the analytical models are compared with experimental data collected in real and artificial soils. In addition, the theories and hypotheses of the root ability to grow in the apical region through nanoindentation, wettability, and photoelasticity are investigated. The first technique provided insights for the possible role and function at both different tissues levels and distances from the tip in the root movement and penetration during the growth. The investigation of root tissue properties revealed that the penetration and adaptation strategies adopted by plant roots could be enhanced by a combination of soft and stiff tissues. The second technique aimed to highlight the wettability of the apical zone and root hairs for the acquisition of water and nutrients. Finally, photoelastic experiments provided a non-invasive and in situ observation of plant roots growth and, by exploiting the fringe multiplication, a set up for the study of plant roots growing in edible gelatine is proposed.

Resumen

The project Roots and Routes is an intergenerational narrative connecting three locations: London, Mandeville and Stockholm, focusing primarily on the histories of women and non-binary people. It looks at what affect it has on our sense of cultural identity to grow up in the diaspora, disconnected from the country of our parents or grandparents. Roots and Routes presents the search for a sense of belonging, whilst existing in the in-between. This report explores the different elements of the project, through text and image.

Resumen

This dissertation is comprised of two separate topics within the domain of polarization optical engineering. The first topic is a Mueller matrix roots decomposition, and the second topic is polarization computer generated holography. The first four chapters of the dissertation are on the topic of the Mueller matrix roots decomposition. Recently, an order-independent Mueller matrix decomposition was proposed in an effort to organize the nine depolarization degrees of freedom. Chapter 1 discusses relevant Mueller matrix decomposition prior art and the motivation for this work. In chapter 2, the critical computational issues involved in applying this Mueller matrix roots decomposition are addressed, along with a review of the principal root and common methods for its calculation. The choice of the pth root is optimized at p = 10⁵, and computational techniques are proposed which allow singular Mueller matrices and Mueller matrices with a half-wave of retardance to be evaluated with the matrix roots decomposition. A matrix roots algorithm is provided which incorporates these computational results. In chapter 3, the Mueller matrix roots decomposition is reviewed and a set of Mueller matrix generators are discussed. The parameterization of depolarization into three families, each with three degrees of freedom is explained. Analysis of the matrix roots parameters in terms of degree of polarization maps demonstrates that depolarizers fall into two distinct classes: amplitude depolarization in one class, and phase and diagonal depolarization in another class. It is shown that each depolarization family and degree of freedom can be produced by averaging two non-depolarizing Mueller matrix generators. This is extended to provide further insight on two sample measurements, which are analyzed using the matrix roots decomposition. Chapter 4 discusses additional properties of the Mueller matrix roots generators and parameters, along with a pupil aberration application of the matrix roots decomposition. Appendix C, adapted from a conference proceedings paper, presents an application of the matrix roots depolarization parameters for estimating the orientation of a one-dimensionally textured object. The last two chapters are on the topic of polarization computer generated holography. In chapter 5, an interlaced polarization computer-generated hologram (PCGH) is designed to produce specific irradiance and polarization states in the image plane. The PCGH produces a tangentially polarized annular pattern with correlated speckle, which is achieved by a novel application of a diffuser optimization method. Alternating columns of orthogonal linear polarizations illuminate an interlaced PCGH, producing a ratio of polarization of 88% measured on a fabricated sample. In chapter 6, an etched calcite square-wave retarder is designed, fabricated, and demonstrated as an illuminator for an interlaced polarization computer generated hologram (PCGH). The calcite square-wave retarder enables alternating columns of orthogonal linear polarizations to illuminate the interlaced PCGH. Together, these components produce a speckled, tangentially polarized PCGH diffraction pattern with a measured ratio of polarization of 84% and a degree of linear polarization of 0.81. An experimental alignment tolerance analysis is also reported.

Resumen

Thesis: M. Arch., Massachusetts Institute of Technology, Department of Architecture, 2017. Cataloged from PDF version of thesis. Includes bibliographical references (pages 78-79). Over the past two decades, more than 200 million people in China moved from rural to urban areas. These migrants fled the countryside, which is regarded as an economic wasteland in perpetual stagnation that is locked by feudal traditions and peasant values, to the largest cities. They sought to be connected to a modern China, one that is marked by a booming economy and pronounced popular culture. These rural- to-urban migrants have formed the largest peacetime inland migration in history. Mobility is a socially produced motion that often bears ideologies. It is associated with a desire for progress, freedom, and opportunity. The massive inland migration in China demonstrates the tremendous social force that aims to overcome the outdated social strata. However, as migrants move, limitations on mobility emerge. The Hukou, the household registration system in China, is an institutional framework that has entrenched the social strata for ages. Records of births, marriages, and moves identify each person with a place. As soon as migrants move from their designated origins, immobility appears: welfare exclusion, job inequity, urban transit inaccessibility, to name just a few. This thesis proposes to study this condition of mobility, immobility and estrangement in the district of Minhang, Shanghai, where 1.5 million migrants currently live and work. Scooter, an emerging fast and cheap personal vehicle, is the protagonist in this story of migrants. Linking closely to migrants' life, scooters are not only their primary means of transportation but also their means of production. Its mobility empowers migrants to move beyond their territory, while its unique scale and flexibility links to rich spatial possibilities. by Xinyi Ma. M. Arch.

Resumen

Abstract Although plants are usually seen as static organisms, they exhibit a wide range of movements that only in recent years have been considered as a source of inspiration for robots. The motion of roots is one of the most interesting, because they are extraordinary diggers, able to navigate in unstructured environments, finding their way around obstacles. Moreover, root growth is featured by high energy efficiency because they penetrate the soil adding new material at their tip, without moving the already grown part, preventing friction from dissipating energy and reducing the inertia. A robot inspired to roots’ growth could be employed in search and rescue operations or in environmental monitoring. In this work the design of a soft robot inspired to root’s growth is presented. The body of the robot consists of a cylindrical plastic membrane folded inside itself. When air is blown from the base, the body of the robot is inflated, and its tip is everted increasing its length. On the external surface some Velcro stripes are mounted, which keep the membrane folded. Inside the tip a head is mounted, where the mechanism controlling the direction of growth is placed. It consists of a housing for some balloons, which can be inflated selectively, and their expansion exerts a pressure on the external surface able to open the Velcro stripes. The direction of growth is controlled by selecting which balloon to inflate. The robot has been built and a kinematic model of its motion in the plane has been developed and compared with experimental results.

Resumen

In this work, a new method is introduced for solving large polynomial systems for the kinematic synthesis of linkages. The method is designed for solving systems with degrees beyond 100,000, which often are found to possess a number of finite roots that is orders of magnitude smaller. Current root-finding methods for large polynomial systems discover both finite and infinite roots, although only finite roots have meaning for engineering purposes. Our method demonstrates how all infinite roots can be avoided in order to obtain substantial computational savings. Infinite roots are avoided by generating random linkage dimensions to construct start-points and start-systems for homotopy continuation paths. The method is benchmarked with a four-bar path synthesis problem.

Resumen

The root strengthening effects on soil behind retaining walls may be quantified by a simplified equation ΔS = 1.2TR(AR/A) where ΔS, TR and AR/A are the shear strength increase, tensile strength of root and root area ratio respectively. However, this effect is ignored during stability analysis due to the possible significant variability of the potential beneficial effect and extreme difficulty in fully characterizing the tree roots and quantifying their effects. In this paper, advancements in the last few decades in biotechnical slope stability are reviewed. Representative models to quantify the mechanical effects of tree roots are studied. If other potential beneficial effects due to existence of roots and suction effect due to transpiration of tree are ignored, the term 1.2, root tensile strength and root area ratio may still be the three key parameters to the root strengthening effect in slope stability.

Resumen

Original objectives: Anatomical study of storage root initiation and formation. Induction of storage root formation. Isolation and characterization of genes involved in storage root formation. During the normal course of storage root development. Following stress-induced storage root formation. Background:Sweetpotato is a high value vegetable crop in Israel and the U.S. and acreage is expanding in both countries and the research herein represents an important backstop to improving quality, consistency, and yield. This research has two broad objectives, both relating to sweetpotato storage root formation. The first objective is to understand storage root inductive conditions and describe the anatomical and physiological stages of storage root development. Sweetpotato is propagated through vine cuttings. These vine cuttings form adventitious roots, from pre-formed primordiae, at each node underground and it is these small adventitious roots which serve as initials for storage and fibrous (non-storage) “feeder” roots. What perplexes producers is the tremendous variability in storage roots produced from plant to plant. The marketable root number may vary from none to five per plant. What has intrigued us is the dearth of research on sweetpotato during the early growth period which we hypothesize has a tremendous impact on ultimate consistency and yield. The second objective is to identify genes that change the root physiology towards either a fleshy storage root or a fibrous “feeder” root. Understanding which genes affect the ultimate outcome is central to our research. Major conclusions: For objective one, we have determined that the majority of adventitious roots that are initiated within 5-7 days after transplanting possess the anatomical features associated with storage root initiation and account for 86 % of storage root count at 65 days after transplanting. These data underscore the importance of optimizing the growing environment during the critical storage root initiation period. Water deprivation during this phenological stage led to substantial reduction in storage root number and yield as determined through growth chamber, greenhouse, and field experiments. Morphological characterization of adventitious roots showed adjustments in root system architecture, expressed as lateral root count and density, in response to water deprivation. For objective two, we generated a transcriptome of storage and lignified (non-storage) adventitious roots. This transcriptome database consists of 55,296 contigs and contains data as regards to differential expression between initiating and lignified adventitious roots. The molecular data provide evidence that a key regulatory mechanism in storage root initiation involves the switch between lignin biosynthesis and cell division and starch accumulation. We extended this research to identify genes upregulated in adventitious roots under drought stress. A subset of these genes was expressed in salt stressed plants.

Resumen

Architecture of a root system is the expression of the potential of various root types to branch, to grow and to coordinate with other plant organs, under the specific limitations of the environmental conditions. The present investigation has proven the following points. 1) Genotypes with different types of root systems were identified. The growth patterns of their roots and the distribution of laterals along their main axes were recorded. 2) The patterns of development of the root systems of four cotton genotypes, throughout the entire life cycle of the plants, were described, even at such a late stage of development when the total length of the roots exceeded two kilometers. To the best of our knowledge, this is the first time that an analysis of this type is accomplished. 3) The development of root systems under restrictive soil conditions were compared with those that have developed under the non-restrictive conditions of aeroponics. Results indicate that in the absence of the mechanical impedance of the soil, cotton plants develop single roots that reach the length of 6 m, and have a total root length of 2000 m. Thus, root growth is strongly inhibited by the soil, with some root types being inhibited more than others. 4) One of the important decisions, in constructing an operational root system architecture of mature plants, is the shift of the balance between various root fractions in favor of the very fine roots. 5) Root system architecture is determined, in part, by the sites of initiation of the lateral roots. This is determined genetically by the number of xylem archs and by the totuosity of the stele. Selection for such traits should be sought.

Resumen

American ginseng (Panax quinquefolius) is a perennial herb of eastern deciduous forests that is harvested for medicinal use. Because of the high market value of its roots, ginseng is threatened in much of its range and is a target for poaching in national parks. In Shenandoah National Park, illegally harvested roots confiscated by law enforcement are replanted in the Park to salvage the roots and reestablish ginseng populations. Ninety-five sites where roots were replanted between 1998 and 2017 were surveyed to determine the plants? survival rate. Population growth was measured as the total number of plants found at each site divided by the number of roots originally replanted. Average population growth across sites was found to be 0.60, or 60% of the number of replanted roots. Ninety-one percent of sites contained at least one plant, and at least 42% contained juvenile plants, indicating that these populations were reproducing. Habitat data collected at each site were analyzed to determine what type of plant communities contained the most successful populations, but the results were inconclusive. Since root condition prior to replanting is likely to be the most important factor in determining survival of replanted roots, basic guidelines were summarized for staff involved in handling ginseng. Twenty-eight 4 x 10 m covert ginseng plots were also resampled 14 years after installation. Plant counts were similar between samples likely indicating consistent poaching pressure.
