ABSTRACT This study aimed to understand the relationship of morphological characteristics and actual evapotranspiration of forage cactus clones with their productive capacity under different water regimes. The data used in this study were collected between the years 2012 and 2013, in Serra Talhada, State of Pernambuco. The clones Sertânia IPA - IPA, Miúda - MIU and Orelha de Elefante Mexicana - OEM were submitted to three irrigation depths (2.5, 5.0 and 7.5 mm) and three irrigation intervals (7, 14 and 28 days). Cladode and plant morphology, accumulated actual evapotranspiration and yield were obtained at the moment of harvest. Pearson’s correlation matrix was elaborated and, in the sequence, multicollinearity, canonical and path analysis were applied. There was no correlation of yield with the soil water supply and actual evapotranspiration of the clones (p > 0.05). Forage cactus yield was more associated with peculiarities of the morphological characteristics of the clones than with the different soil water supplies or the crop actual evapotranspiration. However, regardless of the water regime and clone, the vigor of the basal cladodes was highly decisive for the expression of the forage cactus productive capacity.

AbstractTaking into consideration two facts: that the structure of social life forces twins to part and that the presented roles in a pair are not equal, (one of the twins plays the role of a leader (L) and the other, the subordinate (P.)), one can ask the question — what meaning does the moment of parting have and what are its consequences?In order to do that, a survey was conducted, (a sample of 31 pairs of twins above the age of 30), in which every pair was asked the question: “Which one of you made the decision about parting?” The answer had two options: A – I, B – brother/sister. Out of 31 pairs of twins, 16 pairs chose the variant different from his brother or sister – that is A, B, admitting that the interpersonal conflict was the result of the parting. In 7 pairs, both twins chose the B variant – they withdrew from the conflict; and in 8 pairs they chose the A variant – looking for a compromise as the means of agreement.When analyzing the results of the survey, we can state the following:– in the relationship of twins, there is an interpersonal conflict;– the decision about parting is difficult with prevalent feelings of sadness and sorrow;– after parting, at least one of the twins has problems with preserving his identity and integrity of psychological space.Since the moment of parting is necessary and difficult, specialists and mainly parents are required to consciously change their position towards the relationship of twins. It has to be the result of applied educational methods which aim at creating subjectivity and equality of each of the twins before the moment of parting.

THE RELATIONSHIP OF STUDENTS' UNDERSTANDING LEVEL OF ANIMAL MORPHOLOGY CHARACTERISTICS WITH THE ABILITY TO MEMORIZE ANIMAL LATIN NAMES IN GRADE 10 IPAAbstractAnimal taxonomy subjects often use animal's Latin names. Many students think that this subject is annoying because it is dominated by memorizing animal's Latin names, even though memorizing becomes a prerequisite for understanding. Meanwhile, most of the language materials memorized need an understanding before the memorizing process. This study aimed to find a relationship between the level of students' understanding of an animal's morphological characteristics and the ability to memorize animal's Latin names at the Xth grade of IPA students in SMAN 3 Jember. This study used a quantitative approach with a type of ex post facto. The test obtained the data. Then it was descriptively and inferentially analyzed by Kendall correlation. This research indicated that 56 students who answered test of the level of understanding animal's morphological characteristics and the ability to memorize animal's Latin names resulted in a correlation coefficient of score 0.673, and significance 0,000 < 0.05. Therefore, if the level of students’ understanding of an animal's morphological characteristics increased, the ability to memorize animal's Latin names at the Xth grade of IPA students in SMAN 3 Jember also increased, conversely. AbstrakNama latin hewan sering digunakan dalam materi taksonomi hewan. Banyak siswa beranggapan bahwa materi tersebut membosankan karena didominasi oleh menghafal nama latin hewan, padahal menghafal menjadi prasyarat pemahaman. Sementara itu, sebagian besar materi bahasa yang dihafal membutuhkan pemahaman sebelum proses menghafal berlangsung. Tujuan penelitian ini ialah mengetahui hubungan tingkat pemahaman karakteristik morfologi hewan dengan kemampuan menghafal nama latin hewan pada siswa kelas X IPA SMA Negeri 3 Jember. Penelitian ini menggunakan pendekatan kuantitatif dengan jenis eks post facto. Data didapatkan menggunakan instrumen tes. Kemudian dianalisis secara deskriptif dan inferensial menggunakan korelasi Kendall. Penelitian ini menunjukkan bahwa dari 56 siswa yang menjawab tes tingkat pemahaman karakteristik morfologi hewan dan kemampuan menghafal nama latin hewan menghasilkan koefisien korelasi 0,673 dan signifikansi 0,000 < 0,05. Dengan demikian, jika tingkat pemahaman karakteristik morfologi hewan meningkat, kemampuan menghafal nama latin hewan pada siswa kelas X IPA SMA Negeri 3 Jember juga meningkat, begitupula sebaliknya.

The land of PT. Hide Way Resort area 1.5 ha located in Ngawas village, Pasuruan district, the Province of East Java as at the moment is empty land and was planted apple, Eugenia, red pepper, carrot and pumpkin. It is located almost at the same position with Mount Bromo. This land will be used for accommodation/ 10 villas and 1 meeting room. We have to drive and reach this location and can see the apple and vegetable garden on mountain also very nice scenery we can see during passing this location. Also, we can see the natural village condition and warmest welcome from the people around the village. We can see very nice view after reaching the place by mountain view and hill view in cold temperature. Land and hill view on the area make more convenience to stay here. This kind of location can attract the tourist especially specific tourist who always searching the specific destination since it is not many kind of destination like this. The main concept is staying in natural village with traditional villa style and look like the traditional house in the past including the furniture inside and how to cook the food by burning wood. This kind of situation also completed with daily people around the village activities, traditional art show, transportation to Mount Bromo, golf and other activities. The marketing activities will be used the relationship of the owner with his channels abroad, community of specific tourism, you tube, social media and online travel agent. This opportunity is good to be developed in the future since many inquiry for this kind of specific tourism, increase the economy level of the people around and create more working opportunity.

AbstractBased mainly on an analysis of the host ranges of the species presently placed in Cactodera, sensu lato, and of selected morphological characteristics, an attempt is made to improve the definition of the genus which, after exclusion of C. betulae and C. johanseni, is considered to be monophyletic. The host range of Cactodera, sensu stricto, appears to be restricted to the subclass Caryophyllidae with the ten known species showing an adaptive radiation on host genera in five families of the orders Caryophyllales and Polygonales. This may be a result of co-evolution. Cactodera betulae cannot be assigned to any of the presently recognised genera of cyst-forming nematodes and therefore Betulodera gen. nov. is proposed with B. betulae comb. nov. as the type and only species. The relationship of Betulodera gen. nov. to other genera of Heteroderidae and to some undescribed heteroderid species has still to be evaluated. The new genus is characterised by circumfenestrate cysts with only a slightly protruding vulval cone, three incisures in the lateral field of the second-stage juveniles and presence of phasmids in the males. The hosts are in unrelated plant orders and subclasses. Cactodera aquatica, a species inquirenda, is returned to the genus Heterodera and Heterodera johanseni (Sharma et al. , 2001) comb. nov. is proposed for C. johanseni.

We study the equivariant oriented cohomology ring $\mathtt{h}_{T}(G/P)$ of partial flag varieties using the moment map approach. We define the right Hecke action on this cohomology ring, and then prove that the respective Bott–Samelson classes in $\mathtt{h}_{T}(G/P)$ can be obtained by applying this action to the fundamental class of the identity point, hence generalizing previously known results of Chow groups by Brion, Knutson, Peterson, Tymoczko and others. Our main result concerns the equivariant oriented cohomology theory $\mathfrak{h}$ corresponding to the 2-parameter Todd genus. We give a new interpretation of Deodhar’s parabolic Kazhdan–Lusztig basis, i.e., we realize it as some cohomology classes (the parabolic Kazhdan–Lusztig (KL) Schubert classes) in $\mathfrak{h}_{T}(G/P)$. We make a positivity conjecture, and a conjecture about the relationship of such classes with smoothness of Schubert varieties. We also prove the latter in several special cases.

As part of a 2-year study of the effect of thinning on evapotranspiration in Douglas fir (Pseudotsugamenziesii (Mirb.) Franco), the relationship between stomatal diffusion resistance (rs) and environmental variables were studied. Research was conducted in an unthinned stand (1840 stems ha−1) with negligible undergrowth and a thinned stand (840 stems ha−1) with substantial salal (Gaultheriashallon Pursh) undergrowth. During the daytime rs was mainly related to the soil water potential (ψs) and the vapour pressure deficit (v.p.d.) of the canopy air. Daytime values of rs for Douglas fir ranged from 2 to 60 s cm−1 for values of v.p.d. between 4 and 24 mb (4 and 24 × 102 Pa) and values of ψs between 0 and −12.5 bars (0 and −12.5 × 105 Pa). Although increasing rs was usually associated with decreasing pressure potential of the twig xylem (ψt), increasing rs appeared to be associated with increasing ψt when the v.p.d. was high. Stress history was found to cause a shift in the relationship of rs to ψt, but had little effect on the relationship of rs to v.p.d. and ψs. Daytime values of rs for salal ranged from 2 to 45 s cm−1. This stomatal behaviour suggests that as the soil dried out, salal transpiration accounted for an increasing fraction of the total water loss by the thinned stand.

An analysis of the yield components of rape (Brassica napus L.) was carried out under field conditions for 2 yr at Saskatoon. Plant morphology and the crop environment were altered by the use of four planting densities and three water regimes. The number of branches per plant was scarcely affected by irrigation, but was reduced by high seeding rates. Number of pods per plant was increased by irrigation and reduced by high seeding rates. The number of seeds per pod was increased by irrigation, but reduced by high seeding rates. The 1,000-seed weight was increased both by irrigation and increased seeding rate, as was seed yield. Yield was positively correlated with 1,000-seed weight in both years. Yield component compensation was evident in the relationship of 1,000-seed weight to pod number and number of seeds per pod.

Throughout February 2012, a court sitting at Myanmar’s central prison recorded a defendant’s narrative of torture by policemen to have him confess to a bombing two years prior. How was this record made possible? What does the narrative reveal about the relationship of police torturers to the political community giving them authority to act? Working from Agamben’s intuition that in the moment of violence the policeman occupies an area symmetrical to the sovereign, inasmuch as his use of violence is justified in the name of public order, I suggest the account of police torture in this case can be explained in terms of Hobbes’s theory of attributed action. Like Hobbes’s sovereign, the Burmese policemen had the prerogative to decide when and how to use violence against the detained subject on behalf of the state. That the defendant could later recount to a judge the torture done to him was only because he lacked standing to lay claims against sovereign police, who he himself, as a member of the political community, had authorised. Ironically, the record of his narrative was possible precisely because his claims were without efficacy.

Reference as a logical-semantic category is implemented in the blog text based on a variety of lexical and grammatical means (personal, demonstrative and possessive pronouns, definite article, nominative phrases). At the same time, we consistently differentiate the functional and formal level of analysis (connectivity relations – means of expressing connectivity). The conceptual difference between the functional category and the formal implementation of this category reveals some implications that are important for our study. First, the noun or nominative phrase that acts as a segment of the propositional stimulus message is repeatedly replaced by a certain range of formal (and contextual) anaphoric means. Responding to this message, the interlocutor constructs a mental representation of the relationship of formal or contextual connectivity between the antecedent and the substitute. At the same time, the connectivity tool performs a specific referential function in the mental map of blog communication participants. If the referential interdependence between the antecedent and the substitute becomes contextual, the blogger and respondents identify the similarity of the concepts manifested by these components of the stimulus and reaction, establish not only formal equivalence, but also semantic and pragmatic similarity of the conceptual meanings of the associated language units. In the developed blog, there is a contextual relationship between the indicators of connectivity of thematically correlated constituents and the pragmatic consistency of messages of participants in computermediated communication. In the blogosphere, lexical and grammatical tools that function in an anaphoric or cataphoric function are endowed with such semantics that acquire relevant meaning for the interlocutors only taking into account the previous or subsequent messages. These messages, in turn, turn out to be the context against which these units are identified and interpreted by the blogger and respondents. The relationship of connectedness is manifested not so much in the blog text, but at the moment of perception by the interlocutors of each other’s discursive works. The category of connectedness is a value proportional to the communicative ability of the interlocutors to compare and coordinate the semantics of discursive elements, taking into account the referential schemes activated in their minds.

The importance of the ethical principles of individualism and tolerance in the political ethics of liberalism has been studied from the moment of the emergence of liberal ideology to the present day. Using the conceptions of Russian and foreign philosophers, the author traces the relationship of these principles with the situation of the collapse and crisis of the moral system of the post-modern society. The author claims that the liberal doctrine as a whole has a paradoxical effect on the moral consciousness of the modern person, hindering his self-identification.
