Macroscopic Observation

In Lycopersicum esculentum Mill, and L. pimpinellifolium Dun. ramification modes of plants with determinate and indeterminate habits are studied by macroscopic observation (apex evolution, phyllotaxis, and leaf number of the different branches of a mature plant) and also by analyzing mutated sectors after seed treatment. While the first inflorescence, a cyme, originates from the greater part of the prefloral apex, the top of which bears the first flower, second-order axes come up at the axils of the last two leaves. In all the varieties, the axillary bud of the second-last leaf produces a sympodial lateral ramification. On the other hand, that of the last leaf, which becomes visible on the side of the prefloral apex, as anticipated, immediately bears a second inflorescence in varieties with determinate habit, but makes up the second-order axis of the main sympodium in varieties with indeterminate habit. The characteristics of these two bud patterns are compared.

The construction and evaluation of a job satisfaction inventory for ministers. Job satisfaction is a multidimensional construct indicating the degree of adjustment of a worker to his work. A questionnaire was constructed for measuring the various aspects of job satisfaction of ministers. It was administered to 307 ministers. First and second order factor analyses were performed on the items of the questionnaire. Three strong factors of the job satisfaction of ministers were identified, viz. satisfaction with the work as such, the minister's experience of the relationships between him and his wife on the one hand, and his church council and congregation on the other hand, and his vocational self concept. The implications of these findings are discussed. Opsomming Werkstevredenheid is 'n meerdimensionele konstruk wat 'n aanduiding gee van die mate waarin 'n werker in sy werk aanpas. 'n Vraelys om verskeie aspekte van die werkstevredenheid van predikante te meet, is gekonstrueer. Dit is op 'n steekproef van 307 predikante toegepas. Eerste- en tweedeorde-faktorontledings is op die items van die vraelys uitgevoer. Drie sterk faktore van die werkstevredenheid van predikante is geidentifiseer, te wete die belewing van sy werk as sodanig, die belewing van die verhouding tussen horn en sy vrou aan die een kant, en die kerkraad en gemeente aan die ander kant, en sy beroepselfkonsep. Die implikasies van die bevindinge word bespreek.

Uniform Definition

<p>Along with the general trends of research from traditional Gricean approach to postmodern approach, politeness has been conceptualized as facework, social indexing concept, relational work and interactional work. Based on examination of debates over East group-oriented and Western individual-oriented politeness, first-order and second-order politeness, as well as the universality and relativity of conceptualizations, this paper has roughly demonstrated that the tension between universality and relativity of politeness can help to explain the reason for lack of uniform definition and concept in this field. It is essential for researchers to seek a universal second-order culture-general theoretical construct on one hand, and to look at first-order culture-specific constructs on the other hand.</p>

Unique Spin

A wave equation is given which, in the force-free case, describes a particle of unique spin and mass and which remains consistent when interactions are included. The equation is simple in the sense that it involves only matrices which satisfy the Pauli commutation rules. This simplicity is achieved at the expense of extending the particle field vector from one of 2j + 1 components to one of 4j. However, the extra 2j — 1 components are just what are needed to remove the inconsistency of the interacting system. In the force-free case these additional components vanish and the resulting equations are equivalent to the usual ones of Dirac, Fierz and Pauli. One the other hand, for the interacting system, the extra components do not vanish. The second order propagation equations are deduced in the case of external electromagnetic and gravitational fields.

Four Levels

 A field experiment was conducted to evaluate the effect of vermicompost and chemical fertilizers on the performance of Pak choi (Brassica rapa CV. Hong Tae) in Chitwan Nepal during November 2012 to January 2013. Four levels of vermicompost (0, 5, 10 and 15 t/ha) and four levels of NPK equivalent in the form of inorganic fertilizer (100, 50, 25 and 0% of recommended doses of 100:60:60 Kg/ha) in 16 combinations were assessed for yield, yield contributing parameters of Pak choi and microbial activities of soil. All levels of chemical fertilizers increased plant height, leaf number and chlorophyll content of leaves but they had no effect in increasing root length. Chemical fertilizers at 100:60:60 kg NPK/ha increased biological and economic yield of Pak choi. However, all levels of chemical fertilizers were found strongly suppressing in soil microbial activities. Vermicompost on the other hand increased root length, leaf number, biological and economic yield and more significantly increased soil microbial activities resulting in increased level of soil respiration. Chemical fertilizers were effective in increasing plant growth but suppressed microbial activities of soil. Vermicompost on the other hand was effective in long run through slow release of plant nutrients and improving soil health by increased soil microbial activities.Journal of the Institute of Agriculture and Animal Science.

Ancient Usage

The concept of symmetry is omnipresent, although originally, in Greek antiquity, distinctly different from the modern logical notion. In logic a binary relation R is called symmetric if xRy implies yRx. In Greek, ‘being symmetric’ in general usage is synonymous with ‘being harmonious’, and in technical usage, as in Euclid's Elements, it is synonymous with ‘commensurable’. Due to the second meaning, which is close to the etymology of συ´μμετρoς, ‘with measure’ has likewise to be read as ‘being [in] rational [ratios]’ and displays the origin of the concept of rationality of establishing a proportion. Heraclitus can be read as a master of such connections. Exercising rationality is a case of simultaneously finding and inventing symmetries. On that basis a proposal is made of how to relate the modern logical notion of symmetry, a second-order concept, on the one hand with modern first-order usages of the term symmetric in geometry and other fields, and on the other hand with the notion of balance that derives from the ancient usage of symmetric. It is argued that symmetries as states of balance exist only in theory, in practice they function as norms vis-à-vis broken symmetries.

AbstractWe consider the Schrödinger operator on the halfline with the potential $$(m^2-\frac{1}{4})\frac{1}{x^2}$$ ( m 2 - 1 4 ) 1 x 2 , often called the Bessel operator. We assume that m is complex. We study the domains of various closed homogeneous realizations of the Bessel operator. In particular, we prove that the domain of its minimal realization for $$|\mathrm{Re}(m)|<1$$ | Re ( m ) | < 1 and of its unique closed realization for $$\mathrm{Re}(m)>1$$ Re ( m ) > 1 coincide with the minimal second-order Sobolev space. On the other hand, if $$\mathrm{Re}(m)=1$$ Re ( m ) = 1 the minimal second-order Sobolev space is a subspace of infinite codimension of the domain of the unique closed Bessel operator. The properties of Bessel operators are compared with the properties of the corresponding bilinear forms.

The desirable future coconut variety characteristics should include (1) short trunk and low height increment, (2) early bearing, (3) high nut yield, and (4) high neera (coconut sugar sap). High yoelding but short coconut palm statures make it easy to harvest the nuts and tap the neera. The Dwarf coconut varieties are generally early bearing with a low height increment and plenty nuts per fruit bunch. The Bido tall coconut bears fruits as early as three years after planting and with high nut yield, a low height increment and a very short trunk. This study aims to evaluate early vegetative growth (2 – 3 years after planting) of eight coconut hybrids derived from combinations of Dwarfs x Bido tall hybridizations. The arrays of hybrid coconuts consisted of hybridization between three Dwarf coconut varieties by Bido tall generated in 2016, and those between five Dwarf coconut varieties by Bido tall generated in 2017. The KHINA-1 hybrid was used as the standard hybrid control. Results of the evaluation showed the evaluated Waingapu Red Dwarf x Bido tall hybrids have the largest stem girth and the highest plant heightOn the other hand, Aromatic Green Dwarf x Bido tall hybrids showed the highest leaf numbers. However, all hybrid combinations showed the same stem girth diameter at two years after planting. At two and three years after planting, the Raja Brown Dwarf x Bido tall hybrids were the tallest, while the Nias Yellow Dwarf x Bido tall coconut hybrids have the highest leaf number. All of the Dwarf x Bido tall coconut hybrids showed good vegetative performance at two and three years after planting. The differences in early vegetative performances among the evaluated Dwarf x Bido tall might indicate the differences in early bearing, high nut yield and high neera characters of the hybrids.

NFP is the predicative fragment of NF. In this system we do not allow a set to exist if it cannot be defined without using quantifiers ranging over its type or parameters of a higher type. NFI is a less restrictive fragment located between NFP and NF.We show that NFP is really weaker than NFI; similarly, NFI is weaker than NF. This result will be obtained in the following manner: on the one hand, we will show that NFP can be proved consistent in elementary arithmetic and that second order arithmetic is interpretable in NFI; on the other hand, we will prove the consistency of NFI in third order arithmetic, which is contained in NF.The paper is divided in four sections. In §1, we define the concepts needed and collect a few results together in such a way that they will be ready for later use. In §2, we will present a model-theoretic (quick) proof of the consistency of NFI (and thus of NFP). The proof will be chosen (it is not the quickest!) so as to motivate in a natural manner the details of the proof-theoretical version of it that will be presented in §3. §4 will be devoted to the axiom of infinity in NFP and NFI.

Raman spectra of NaCl crystals doped with Ag+ ions up to 3.5 mol% have been measured in 4 scattering geometries. In the impurity induced part of the Eg- and F2g-spectra the strongest peaks are located at 85 and 171 cm-1. Their intensities increase proportional to the silver concentration. The second order Raman spectrum on the other hand appears to be independent of the Ag+ content. The spectra are fully explained by theory and by the assumption of Ag+ pairs

Goal. Fungicide application fungicides, applied separately and at the background of using inoculum Rhizoactive, on the formation of yielding capacity and some structural parameters of soy crops. According to the set goal, the task was to select the most effective fungicides to fight diseases in the crops, when they are applied separately and at the background of seed inoculation with Rhizoactive. Methods. Field and laboratory. Results. It has been established that the formation of the yielding capacity of soya and indexes of crops structure depends on the fungicides type and their application against the background of using inoculant and without it. It has been proved that the highest productivity of soya crops formed in the variants of the experiment with the application of Impact K, 0.8 l/ ha and Coronet 300 SC КС, 0.8 l/ha against the background of treatment of soya seeds with Rhizoactive. Conclusions. Application of fungicides Akanto Plus 28 KC, 1.0 l/ha, Amistar Extra 280 SC, KC, 0.75 l/ha, Bamper Super 490, KE, 1.5 l/ ha, Impact K, 0.8 l/ha, Koronet 300 SC, KC, 0.5 l/ha in the crops of soy at the background of pre-sowing seed treatment with  inoculum leads to the increase of yielding capacity of crops by 11—15% and improved structure of crops, which is, on the one hand, provided by the improving phytosanitary state of soy crops under the action of fungicides, and on the other hand, by the nutrition of plants at the background of activation of legume inoculum.
