Characterization of Mukundpura Carbonaceous Chondrite

Two meteorite fragments collected from the Mukundpura impact site, Rajasthan, India have been analysed using scanning electron microscopy, energy dispersive X-ray spectroscopy, Mossbauer spectroscopy, thermogravimetric analysis (TGA) and Raman spectroscopy. High Fe (22.65 wt%), Ni (1.53%) and S (3.69%) and concentrations of other elements obtained by X-ray analysis indicate that it is a carbonaceous chondrite. Mossbauer spectra show similarity with those obtained from Cold Bokkeveld and Murchison carbonaceous chondrites, and this analogy allows us to classify it as belonging to CM group of carbonaceous chondrites. TGA shows large weight loss, implying presence of significant amount of volatiles in this meteorite and Raman spectroscopy shows the presence of abundant organic matter consisting of disordered and aromatic (graphitic or polyaromatic) carbon. These results indicate that Mukundpura meteorite is a rare type of extraterrestrial object deserving further in-depth studies.
Performance of Hybrid Tea Rose cv. Bugatti in Response to Growth Regulators

Rose is called “Queen of Flowers” by Sappho, a poetess more than 2500 years ago. Rose belongs to the family Rosaceae. Roses (Rosa hybrida L.) are one of the most important commercial crops grown for a variety of purposes such as pot plants, garden plants and cut flower production. Among all other cut flowers roses lead in popularity because of their beauty, fragrance and long lasting blooming quality (Ghaffor et al., 2000; Tabassum et al., 2002). It possesses multiple uses like extraction of essential oils, Vit. C from hips for medicinal uses and as cut flowers (Khan, 1978). Roses are also used in the preparation of rose water, gulkand, pankhuri, gul-roghan, Potpouri, conserves, rose vinegar, rose petal wine, jam, jellies and syrups etc.
A survey study based on undergraduate medical students’ feedback regarding pathology and the teaching-learning methodologies employed

Background: It cannot be emphasized enough that a solid understanding of pathology is the foundation for a good clinical practice. And, Pathology, being a vast subject with the number of lecture hours being limited, understanding the students’ perspective is essential for generating interest in the subject and for gaining essential knowledge and skills during those limited hours assigned. Aim: This study was aimed at understanding the students’ perspective regarding pathology as a subject and about the effectiveness of the various teaching-learning methods currently used by the faculty of our department. Materials & Methods: This study was carried out on 81 2 nd MBBS students (regular batch) who have completed 3 semesters of pathology using a predesigned questionnaire with questions pertaining to students’ perception of pathology and the various teaching learning methods currently used by the faculty. Results: A vast majority of the students, 96.6%, found pathology to be an interesting subject. About 95% of them agreed that a sound knowledge of pathology was useful during their clinical postings and for their clinical practice. Majority of the students, 76.6%, were satisfied with content of the lectures taken. 93.3% of them felt that enough stress has been laid on important topics during the lecture classes and important points have been highlighted adequately. Popular modes of teaching learning were casebased discussions and group discussion (96.6%), Powerpoint presentations (88%), black board teaching (78.3%), integrated teaching (83.3%). 96.65% of the students agreed that written exams were a very effective assessment tool. Among the changes suggested by the students, the point most mentioned was that more practical exams and monthly tests need to be conducted because pathology was perceived as a vast subject. Lack of effective teacher-student communication was also mentioned in 6% of the feedback forms. Conclusion: Our study showed that most students had a positive attitude towards pathology as a subject as well as the various teaching learning methods employed by the faculty of our department. Most students felt case based discussions and integrated teaching to be among the most effective ways of gaining knowledge.
Comparative Study on Production Efficiency in Native Romanian Carpatina and Banat White Goats

Objective of the current study was to evaluate the milk yield, health, reproductive rate and fitness indicators in two Romanian indigenous goat breeds, selected for milk (Banat White) and unimproved (Carpatina), managed under extensive rearing conditions. Milk yield in Carpatina goats was on average 323.6±1.68 kg/lactation, compared to that of Banat’s White does of 561.4±1.43 kg, differences for milk production under identical rearing conditions being significant (p≤0.001). Prolificacy in the two breeds was significantly influenced by the genotype (p≤0.001), with average litter size of 148.0±0.49% in Carpatina, and 184.8±0.51% in Banat’s White does. Growth rates in the un-weaned kids were on average of 119.8±0.86 g/day in Carpatina and of 134.3±0.76 g/day in Banat’s White breeds (p≤0.05). Adult does annual voluntary culling rate was on average 16.4±1.46 % in Carpatina and of 20.6±1.88% in Banat’s White breed (p≤0.05). Clinical mastitis incidence was significantly lower (p≤0.05) in Carpatina goats (2.88±1.65%) compared to that of Banat White (4.65±2.28%). Significant differences (p≤0.05) for lameness were found between Carpatina and Banat White populations, with occurrence rates of 3.85±1.89% and 5.81±2.54%, respectively. Abortion and pneumonia incidence were not affected (p>0.05) by selection pressure among the two breeds.
Evaluation of Crested Wheatgrass Managed as Turfgrass

Typical turfgrass species often receive substantial inputs of water, fertilizer, chemicals, and cultural management, particularly in the Intermountain U.S. Plant materials that do not require these inputs and that also maintain acceptable levels of turf quality and performance are desirable in low-maintenance/limited irrigation situations. However, there is a lack of plant material that fits this description. Crested wheatgrass is a potential source of turf varieties for semi-arid regions and is the focus of current breeding efforts to improve its turf characteristics. This study examined implications of irrigation interval, mowing height, nitrogen fertilization, and cultivar selection on the performance of crested wheatgrass turf. While irrigation interval, mowing height, and cultivar affected performance, the application of nitrogen fertilization was the critical factor for maintaining the quality of crested wheatgrass turf under the conditions of this study. Regardless of the treatments imposed, crested wheatgrass turf performance declines during the hot summer months.
FANCM-family branchpoint translocases remove co-transcriptional R-loops

Co-transcriptional R-loops arise from physiological or aberrant stalling of RNA polymerase, leading to formation of stable DNA:RNA hybrids. Unresolved R-loops can promote genome instability. Here, we show that the Fanconi anemia- and breast cancer-associated FANCM protein can directly unwind DNA-RNA hybrids from co-transcriptional R-loops in vitro. FANCM processively unwinds both short and long R-loops, irrespective of sequence, topology or coating by replication protein A. R-loops can also be unwound in the same assay by the yeast and bacterial orthologs of FANCM, Mph1 and RecG, indicating an evolutionary conserved function. Consistent with this biochemical activity of FANCM, we show that FANCM deficient cells are sensitive to drugs that stabilize R-loop formation. Our work reveals a mechanistic basis for R-loop metabolism that is critical for genome stability.
Abnormal Shell Shapes in Northern Map Turtles of the Juniata River, Pennsylvania, USA

Abstract Northern Map Turtles, Graptemys geographica, are a long-lived riverine species of conservation concern. We examined carapace morphology of Northern Map Turtles at Mount Union, a major turtle nesting area and former industrial site along the Juniata River in central Pennsylvania, USA. Among 535 reproductive adult female G. geographica, 29% exhibited abnormal shell shape, often in the form of an indentation in one or both sides of the carapace. Older females had a higher incidence of abnormalities than younger females. We quantified variation in shell shape, compared morphology among life history stages, and assessed thermal incubation environments of embryos to determine the magnitude and potential source of shell shape abnormalities. Geometric morphometric analysis showed significant differences among several carapace shape categories of adult turtles. No shell shape abnormalities were observed among 703 hatchlings collected from nests, and no shell shape abnormalities were observed among seven of those marked hatchlings that returned to Mount Union as 11- to 18-yr-old adult females to nest. Historically, most of the nesting substrate at Mount Union consisted of black coal tailings, which exposed developing embryos to high temperatures and potential chemical insults. The high incidence of abnormal carapace shapes of adult female Northern Map Turtles at Mount Union may reflect a delayed morphological response to chemical or thermal conditions encountered in the nesting substrate, direct exposure to contaminants in the Juniata River as subadults, or factors that affected turtles a generation ago but have since abated.
Variation in the body growth parameters of the ghost crab Ocypode quadrata from morphodynamically distinct sandy beaches

Os padroes de distribuicao da macrofauna de praias arenosas tem sido amplamente investigados, mostrando que o entre-mares de praias dissipativas tende a concentrar maiores valores de riqueza e biomassa, bem como individuos de maior sucesso reprodutivo e tamanho, do que praias reflexivas. Para crustaceos do supralitoral essa tendencia e em geral oposta. Para o guaruca, Ocypode quadrata, frequentemente o grupo mais conspicuo desses ambientes, sao raras as investigacoes de dinâmica populacional e respostas a diferentes morfologias praiais. Aqui, a variacao de tamanho e o crescimento corporeo foram avaliados ao longo de um ano atraves do metodo indireto em tres praias com reduzido impacto antropico no Litoral Norte de Sao Paulo. Estas foram escolhidas de froma a representarem tres tipos basicos de morfodinâmica: dissipativa (Costa), intermediaria (Felix) e reflectiva (Puruba). Em cada praia, cinco transectos de 2m de largura foram aleatorizados mensalmente, e avaliados da primeira a ultima ocorrencia de tocas. O ajuste do modelo de crescimento de von Bertalanffy foi comparada entre as areas. Para as tres praias uma moda principal, devido a entrada de juvenis (mm), foi identificada em agosto/setembro. Esses individuos atingiram no verao seguinte um tamanho correspondente a moda principal do verao anterior, e dentro daquela que foi dominante no periodo como um todo. Especificamente, os parâmetros de crescimento foram: Costa (dissipativa) L∞ = 46,36 milimetros, K = 0,90 ano-1 e t0 = -0,19; Felix (intermediaria) L∞ = 57,95 milimetros, K = 0,87 ano-1 e t0 = -0,12; Puruba (reflexiva) L∞ = 53,01 milimetros, K = 1,11 ano-1 e t0 = -0,07. Esses ajustes foram iguais estatisticamente entre Puruba e Felix, sendo ambos distintos da praia do Costa. Os indices de crescimento, phi-prima, variaram de 3,29 (Costa) a 3,49 (Puruba), enquanto na praia Felix esse valor foi 3,46, indicando homogeneidade deste parâmetro entre as praias, mas reforcando a maior semelhanca a praia intermediaria e reflexiva.
GROWTH PERFORMANCE AND FORAGE NUTRIENT CONTENT OF MORINGA (MORINGA OLEIFERA LAM) PROVENANCES UNDER LUYENGO CONDITIONS, SWAZILAND CONDITIONS

The incorporation of tree and shrub species in animal production systems is a viable alternative to improve the utilisation of land and at the same time improve the diet of livestock. Scarcity of animal feed resources, particularly during the dry season, is a major constraint to livestock production in Swaziland. Therefore, alternative feed resources need to be investigated. Moringa oleifera (Lam) leaves can be used as animal feed. Its growth performance and nutritive value has not been documented in the country. The objective of the study was to determine the growth performance and chemical composition of three provenances of Moringa. The three provenances evaluated were Mayiwane, Malawi and Binga in a completely randomised design with three replications. The Moringa was measured for growth performance for 12 weeks and harvested after 16 weeks for chemical analysis. The plant height for Mayiwane provenance ranged from 8.86 cm to 51.25 cm, Malawi provenance ranged from 6.61cm to 40.79 cm and Binga provenance ranged from 2.71cm to 40.79 cm. Root collar diameter for Mayiwane provenance ranged from 0.196 cm to 0.625 cm, Malawi provenance ranged from 0.144 cm to 0.526 cm and Binga provenance ranged from 0.065 cm to 0.531. The three provenances had significant (P 0.05) differences in CP, CF, OM and ash content among the provenances. Mayiwane provenance had the highest DM value of 21.22% and was not significantly different (P > 0.05) from Binga provenance which was 20.72%. It is concluded that Mayiwane provenance can be utilised for its fast growth rate and its adaptability to Luyengo for large scale forage production.
Genetic Variability and Inter Relationship among the Gene Pyramided BC4F4 Generation Lines for Yield and Yield Attributing Characters in Rice (Oriza sativa L.)

Rice (Oryza sativa L.) is the staple food for more than half of the world’s population (Akhtar et al., 2010). China and India account for more than half of the world’s rice areas and consume more than three – quarters of the global rice production (Hossain, 1997; Maclean et al., 2002). It is probably the most diverse crop as it is produced in a wide range of locations and under a wide variety of climatic conditions from the submerged areas in the world to the dried deserts. In the rice, major economic losses in the field are due to various biotic stress including insect pests like stem borer, brown plant hopper (BPH), green leafhopper (GLH), leaf folder and gall midge and diseases like blast, bacterial blight (BB), sheath blight, leaf spot, sheath rot.

Effect of presence of corpora lutea on cumulus expansion of in vitro matured bovine oocytes selected by trypan blue and brilliant cresyl blue tests

ABSTRACT Trypan Blue (TB) and Brilliant Cresyl Blue (BCB) are used to select and determine viability and competence of oocytes, however, the effects of corpora lutea on cumulus expansion during in vitro maturation are still undetermined. Cumulus-oocytes complexes (COCs) from ovaries with ipsilateral (ICL), contralateral (CCL) and without corpora lutea in either ovary (OCL) were selected by visual examination, TB and BCB staining, and matured in vitro to evaluate cumulus expansion. The overall percentage of visually selected COCs was similar in ICL, CCL and OCL (P > 0.05). Proportions of live and mature COCs were similar in all groups (P > 0.05). The overall percentage of BCB+ COCs was 70.1%. BCB+ ICL COCs had less cumulus expansion (60.5%) than BCB+ CCL and OCL COCs (75.7 and 71.4%, respectively; P < 0.01). BCB− ICL COCs had less cumulus expansion (20.0%) than BCB− CCL and OCL (39.7 and 46.1%; P < 0.01). BCB+ CCL and OCL COCs showed the highest cumulus expansion index (P < 0.01). Presence of corpus luteum in the ovary affects negatively cumulus cells expansion. TB and BCB staining facilitate the selection of oocytes with higher degrees of cumulus expansion.

Flow Boiling Characteristics in a Microchannel with Various WettabilityPatterned Surfaces

Flow boiling in a microchannel is an effective and attractive solution for thermal management. In this work, flow boiling was performed in microchannels with various wettability-patterned dotted surfaces. Pitch distances of dots were changed to study the wettability pattern effects on microchannel flow boiling. Glass-silicon-glass microchannels integrated with internal platinum heaters and various wettability patterns were fabricated and characterized using MEMS techniques. The transparent top of the channel allowed visualization of bubble dynamics and flow patterns. The hydraulic diameter of the microchannel is 338 μm, the side length of hydrophobic dots is 72 μm and the pitch distances of hydrophobic dots change from 122 μm to 172 μm. Bubble dynamics and flow patterns were visualized using a high-speed camera and a microscope. Heat transfer performance, including boiling curves and heat transfer coefficients (HTC), were explored experimentally under different mass flux. It is found that bubbles coalesce more frequently and flow pattern transitions are more intense with the decrease of pitch distance. In the low mass flux region, better heat transfer capability can be observed on the surface with larger pattern pitch distance, while with the increase of mass flux, a microchannel with smaller dot pitch distance presents better heat dissipation ability. Moreover, the critical heat flux (CHF) decreases with the decrease of dot pitch distance. The reasons behind these phenomena are related to the bubble coalescence, bubble density, and flow movement.

The effects of L-lysine in the diet of silver catfish (Rhamdia voulezi) female broodstocks

The objective of this study was to assess the L-lysine effect in silver catfish, Rhamdia voulezi female reproduction. Four hundred fish were used distributed in a random in 16 net cages (25 fish each × 4 replicates = 100 fish per treatment). The treatments consisted in four diets, isoproteic and isoenergetic (30% crude protein and 3,500 kcal kg -1 digestible energy) with different L-lysine levels: T1: 1.30; T2: 1.40; T3: 1.60 and T4: 1.95%. After 185 days of experiment 18 females per treatment were weighed, measured, and submitted to hormonal induction (0.5 and 5.0 mg kg -1 Carp Pituitary Extract). The females were then sacrificed and had their ovaries, liver and fat removed and the respective organosomatic indices were estimated. With regard to the reproductive parameters, the released oocytes, absolute fecundity and remaining ovaries were influenced ( P 0.05). We can conclude that L-lysine affects the reproductive parameters and accumulation of visceral fat in R. voulezi .
Longitudinal immunosequencing in healthy people reveals persistent T cell receptors rich in public receptors

Background The adaptive immune system maintains a diversity of T cells capable of recognizing a broad array of antigens. Each T cell’s specificity and affinity for antigens is determined by its T cell receptors (TCRs), which together across all T cells form a repertoire of tens of millions of unique receptors in each individual. Although many studies have examined how TCR repertoires change in response to disease or drugs, few have explored the temporal dynamics of the TCR repertoire in healthy individuals. Results Here we report immunosequencing of TCR β chains (TCRβ) from the blood of three healthy individuals at eight time points over one year. TCRβ repertoires from samples of all T cells and memory T cells clearly clustered by individual, confirming that TCRβ repertoires are specific to individuals across time. This individuality was absent from TCRβs from naive T cells, suggesting that these differences result from an individual’s antigen exposure history. Many characteristics of the TCRβ repertoire (e.g., alpha diversity, clonality) were stable across time, although we found evidence of T cell expansion dynamics even within healthy individuals. We further identified a subset of “persistent” TCRβs present across all time points, and these receptors were rich in clonal and public receptors. Conclusions Our results revealed persistent receptors that may play a key role in immune system maintenance. They further highlight the importance of longitudinal sampling of the immune system and provide a much-needed baseline for TCRβ dynamics in healthy individuals. Such a baseline should help improve interpretation of changes in the TCRβ repertoire during disease or treatment.
Yield, berry quality and physiological response of grapevine to foliar humic acid application

Bragantia, Campinas, v. 77, n. 2, p.273-282, 2018 ABSTRACT: Environmentally friendly grape growing is an important objective of modern viticulture. The aim of the study was to examine the response of two grapevine Vitis vinifera L. cultivars to humic acids (HA) foliar application as biostimulant in order to provide sustainable viticultural practices for farmers. The experiment was carried out under field conditions and repeated in two consecutive years. In order to evaluate the effect of humic acids application, the grapevines were treated with three concentrations: 30 ml.L-1 (HAT1), 40 ml·L -1 (HAT2) and 50 ml·L-1 (HAT3). The grapevines were represented by two grape varieties: cv. Feteasca Regala (cv. FR) and cv. Riesling Italian (cv. RI). CROP PRODUCTION AND MANAGEMENT Article
