Aim. The paper presents the results of assessment of the indigenous nature and  degree of similarity of apricot cultivars growing in the collection of the Mountain  Botanical Garden, Gunib, Dagestan, Russia based on a comparative analysis of the  variability of leaf morphological characteristics.   Material and Methods. The material assessed consisted of 33 apricot cultivars of  various ecological and geographical origins aggregated in the following groups: (a)  Dagestan – traditional cultivars; (b) Moscow ‐ selection from the Tsytsin Main Moscow Botanical Garden, Russian Academy of Sciences based on wild forms of Tajikistan and Kyrgyzstan; (c) European and (d) Asian ‐ from Central Asia, Tajikistan, China  and Altai.   Results. The closeness of Dagestan and European varieties in comparison with Asian  and Moscow varieties was shown. Most Dagestan (16 of 19) and European varieties  have round‐shaped leaves (leaf shape index 80‐ 100%), while those from Asia and  the Moscow Botanical Garden have leaves which are elongated elliptical and oval  (60‐80%). Using the method of principal component analysis (PCA), it was established that most cultivars of Dagestan origin have similar leaf shapes and sizes, of  which Tlama kurak (wide‐round), Hekobarsh (elongated) were distinguished by leaf  shape and Esdelik by leaf size.   Conclusion. Based on a discriminant analysis (Squared Mahalanobis Distances), it  was found that the indices of indicators of leaf attributes (width/length of leaf lamina; petiole length/length of lamina; apex angle/corner of leaf base) are more reliable criteria for differentiating apricot varieties into ecological and geographical  groups than their morphological characteristics.

Abstract Picralima nitida is an important African medicinal plant species used in pharmaceutical industries and traditional medicine to treat several diseases. Despite its importance, the species faces conservation problem. This study evaluated the effect of climate and habitat on morphological characteristics and fruit production of P. nitida. A total of 132 fruiting trees was randomly sampled from three habitat types (home gardens, botanical garden and natural forest) and three soils (Nitisols, Arenosols and Acrisols) in Dahomey Gap and Guineo-Congolese zone. A total of 5 morphological traits and fruit production were recorded per tree to describe the relationship between morphological determinism of the species and climate. Pearson correlation was performed to identify the suitable habitat type in each climatic zone. Harmonized World Soil Database was used to determine physicochemical characteristics of the soil types on which the species occurred. Results revealed that the climatic zones (p < 0.001) and habitat types (p < 0.0001) influenced significantly the morphological characteristics and fruit production of P. nitida. High trees with more number of fruits were observed in home gardens on acid soils (Nitisols (pH: 5) and Arenosols (pH: 5.3)) in Dahomey Gap. In Guineo-Congolese zone, the species was more present in natural forest on acid Acrisols (pH: 5).

This paper reports the first record of intersexuality from Porcellana platycheles, a member of the family Porcellanidae. Intersex individuals were identified by the presence of both pairs of genital openings on the coxae of the third and fifth pereiopods respectively, and by morphological characteristics of the abdomen and pleopods. The low occurrence of this condition suggests that intersexuality is due to genetic variations in the population rather than other possible causes of intersexuality previously reported in other decapods.

This is an experimental study of lung morphology in modeling sepsis on a background of severe purulent-inflammatory disease of soft tissues (necrotizing fasciitis) by original authors’ method. The study showed that early stages of sepsis (1-3 days) were characterized by manifestations of changes in lung tissue as vascular response, in the second period (the 7th day) by appearance and growth of non-obstructive microatelectases, whereas the third period (the 14th day) was characterized by progression of purulent-necrotic processes in soft tissues, development of surgical sepsis and acute respiratory distress syndrome. These changes in morphological structure of lung tissue are specific for generalized septic process and consequences of necrotizing fasciitis with its septic complication.

Sam bo chinh (Abelmoschus sagittifolius (Kurz) Merr.) is a precious medicinal plant that has been exploited and planted in Vietnam for a long time. However, the morphological characteristics of this plant is easy to confuse with other species of the same genus. In addition, the microscopic characteristics and medicinal powder composition of this medicinal plant have not been comprehensively described. The present investigation was aimed to determine the morphological and microscopic characters of Sam bo chinh using comparative morphology, anatomical research and medicinal powder analysis. The complete description of morphological and microscopic characteristics reported in this study will serve as valuable data for the conservation and development of this species in Vietnam.

Learning styles, language learning strategies, and ethnicity are three important factors in language learning. The information about these three things is very useful for language teachers to prepare and implement effective language learning. This study was conducted to describe the students ' learning style and language learning strategy and to know the similarities/differences from the two elements of Java, Papua, Flores, Dayak, and Batak ethnics. A number of 175 participants were involved in the study. Research data were obtained through the Fleming's learning VARK questionnaire and a language learning strategy questionnaire from Oxford. The results of the two questionnaires were analyzed to determine the type of learning style and language learning strategy. The first finding suggests that the main learning styles of students from the five ethnics are variants [aural] and [kinesthetic] including variations in bimodal, and trimodal. The second finding shows that the major language learning strategy is metacognitive and affective. The third finding reveals some similarities and unique differences in their learning style and learning strategy.

We examine a case of homophobic language online, specifically the deployment of the phrase “no homo,” shorthand for “I’m not a homosexual.” An analysis of 396 instances (comprising 1061 individual tweets) of the use of the phrase “no homo” on the social media platform Twitter suggests that the phrase is a gendered epithet that conveys cultural norms about masculinity. The first finding is that the phrase is used more often by male tweeters than by female tweeters. The second, as predicted by the literature on homophobia, is that the phrase is used in a negative emotional context to convey disapproval for men’s homosexuality or behavior that is not gender normative. The third finding is that the modal use of the phrase “no homo” is in a positive emotional context, accompanying expressions of men’s pleasure, desire, affection, attachment, and friendship. Our analysis suggests that the phrase “no homo” is a gendered one, primarily used by men to facilitate a particularly masculinized construction of positive emotional expression. Our research adds to and complicates findings on the relationship between homophobia and masculinity that suggests that homophobia is an organizing principal of masculinity in western cultures.

Araceae is one type of plant that has a fairly high level of diversity and also rich in benefits such as a source of food, ornamental plants, and medicine. Research on the characteristics of Araceae in Indonesia is still limited. The purpose of this study was to identify Araceaeplants based on morphological structure and analyze the morphological characteristics ofAraceae in Liwa Botanical Garden, West Lampung. This research was conducted from November 2019 to January 2020. Data were collected at Liwa Botanical Garden, WestLampung based on exploration and observation collection methods. Morphological structure data were analyzed as descriptive and qualitative. The parts of plants that are compared between Araceae plants are the shape, size of leaves, petiole, and inflorescences. Observations show that 21 genera of Araceae are consisting of 26 plants. Araceae plants have three different ways of life, namely terrestrial, epiphytic, and aquatic. The shape of the leaves is ovatus, cordatus, lanceolatus, cuneatus, needle, peltatus, sagittatus, hastatus, palmatisect, bipinnatisect and tripinnatisect. The characteristics of this plant have compound interest with cob types (spadix) which are covered by a spatha with two types of inflorescences, namely unisexual and bisexual.

Several morphometric and morphological characteristics were evaluated to determine their usefulness in identifying the life stages of Xiphinema bakeri. The stages can be identified by length of the body, onchiostylet, and replacement stylet of larvae. These values increase lineally from first-stage larva to adult, and fall into five groups corresponding to the nematodes' four larval stages and adult. Each stage has a specific tail-tip shape, which gradually changes from subacute in the first and second stages to subdigitate in adults. At lower magnifications, the body length and the tail shape, used in combination, are best for identification. First-stage larvae also have the replacement stylet overlapping the stylet extension, distinguishing them from the second stage. Frequently the immature vagina of fourth-stage larvae appears as a clear area in the body; this helps to separate them from the third stage.

Objective. The aim of this study was to evaluate the morphological characteristics of the palatal rugae in Korean subjects to determine whether the palatal rugae can be used as an appropriate reference area for three-dimensional digital model superimpositions. Materials and Methods. In total, 343 patients (110 men, 233 women; mean age, 25.6±8.2 years) who had a digital model taken at their initial visit were included, and the numbers and types of right and left palatal rugae were investigated according to the primary, secondary, and fragmentary rugae. Finally, the differences in the positions of the third primary ruga were investigated according to the presence of additional rugae posterior to the third primary ruga. Results. The number of primary palatal rugae ranged from one to six, with 43.5% of the subjects having three primary rugae and 36.1% having four primary rugae; there were no significant differences between sexes. Except for the fragment rugae, the numbers of primary and secondary rugae were not significantly different between the left and right sides. The third primary ruga was located more significantly anteriorly when there was an additional ruga posterior to the third primary ruga (P < 0.001). Conclusions. The numbers of the palatal rugae vary greatly among individuals, and this affects the anteroposterior position of the third primary ruga. When the third primary ruga is located anteriorly, care should be taken when using it as a reference area for superimposition with a digital model before and after orthodontic treatment.
