Effect of Kusha Swarasa in the Management of Mootravaha Sroto Dusti Vikara
No full textMutravaha Srotas is one among the Abhyantara Srotas, concerned with Utpatti, Visarjana of Mutra and maintaining the Kledata in the body. Causes for kidney function are not specific and might include Obstruction of urination, burning micturition, excessive urination, scanty urination, feeling generally unwell, having a reduced appetite over a period of long duration. Among Trinapanchmula Kusha is the one that promote the urine formation thereby flushing the kidneys and urinary tract while eliminating any excess water retention, and to remove the Mutra from the body. In day today practice it is not up to the mark being Ayurveda Profesionalists as limited utility of Trinapanchamoola in therapeutic usage were common community uses in the form of grass juice in their routine practice for accurate documentation. Here an effort made to understand the utility of drug Kusha Swarasa in clinical practice for the management of Mootravaha sroto vikara. Aims and objectives: To evaluate the effect Kusha of on Mutravaha Srotas. Materials and methods: 30 elderly peoples aged between 60 to 75 years are selected by random sampling method and separated as control and study group. Fresh Leaves of the Kusha grass is taken, juice is extracted and given as per the standard dose of Swarasa. It is given in early morning before having the food for 7 days along with Madhu is used as Anupana and 15 days follow up is done. Observations and result: Kusha Swarasawas effective in elderly old age peoples. Discussion and Conclusion: Kusha Swarasa is significantly effective in treating Mutravaha Sroto Dusti Lakshana of apparently healthy elderly old age peoples.

Mechanical properties analyses of bolted joint of Kusha and Nacha fiber composite laminates
No full textAbstractResearchers have been inspired to work on natural fibres as a replacement for man-made synthetic fibres in many lightweight, medium-load applications by the demand for environmentally friendly materials. In this research work, Kusha and Nacha fibre composite laminates have been made by using general-purpose polyester resin to study the possibility of using it as a new material. And its mechanical properties were evaluated. The fibre mat was fabricated by using a weaving setup tech nique and fabrication of laminates with [0°/0°, −45°/45°, and 0°/90°] degree orientations by hand lay-up. The mechanical properties like tensile, shear, and bearing strengths of bolted joints of Kusha and Nacha fibre composite laminates were investigated experimentally. The 18 different laminated composite plate specimens have been tested to observe the influences of joint geometry and stacking sequence on the failure mechanism. Comparisons have been made between the Nacha and Kusha composite fibre laminates in order to determine different failure modes. The mechanical properties of Kusha fibre laminates showed maximum average tensile strengths of 70.05 MPa, bearing strengths of 118.6 MPa, and shear strengths of 32.14 MPa. Whereas Nacha fibre laminates showed maximum tensile strengths of 101.6 MPa, bearing strengths of 149.9 MPa, and shear strengths of 40.2 MPa. Nacha fibre laminates showed more mechanical strength than Kusha fibre laminates. Generally, for this tensile, shear, and bearing strength test of [0°/0°], [−45°/45°], and [0°/90°] angle play for Nacha and Kusha fibres, [0°/90°] angle play has better bearing and shear strength than other angle arrangements
Colouration and Performance Evaluation of Ethiopian Kusha Fibres
No full textBast fiber dyeing process is common practice as the value addition of most bast fibers demanded for various commercial and household applications. In this research work, kusha fiber (extracted previously) was subjected to dyeing using direct, reactive, vat and cationic dyes for the first time. Dyeing process was perfrmed using concentrations 0.5%, 1%, & 3% (W/W) dye to fiber with MLR 1:20. After dyeing process, performance of dyed fiber and tensile tests were conducted. The results revealed that K/S value of all dyed kusha fiber samples increases as the concentration of dyes applied increases. The dyed fibers color fastness to washing was found good both in dry and wet rubbing fastness. Reactive dyed samples have shown good rubbing fatness performance over the others. Regarding light fastness, the result shows there was good performance for all samples according to blue wool light fastness standard that exceeds 6. The tensile strength and elongation of dyed samples showed slight decrement both in vat and direct dyed samples; whereas, considerable decrement was observed both in reactive and basic dyed samples due to formation of covalent bond and acid processing medium

Diagnosis. Percina kusha is distinguished from all other described species oîPercina by a combination of the following characteristics: absence of bright colors on body and fins of adults; no orange band in spinous dorsal fin; no broad vertical bands on body extending dorsally across the back joining those of the other side; 7-11 lateral blotches connected to form a continuous dark brown to black lateral stripe with undulating margins; lateral stripe continuous with large, quadrate basicaudal blotch that extends onto base of caudal fin rays; small, dark blotch on upper and lower portion of caudal fin base, dorsal blotch typically darker; body below lateral stripe white to cream colored, without dark blotches, dusky in breeding males; suborbital bar absent or very poorly developed; lateral line complete, typically no pored scales on base of caudal fin; males with row of modified scales on midline of belly and one or two modified scales between base of pelvic fins; modified breast scale absent; nuptial tubercles absent; anal fin of breeding males not excessively elongate; males without caudal keel as a ventral extension of the caudal peduncle; snout not projecting beyond anterior margin of upper jaw; well-developed premaxillary frenum; serrae on margin of preopercle absent; branchiostegal membranes overlapping or very narrowly joined. Percina kusha is distinguished from the other two species described herein by a combination of the following characters: dorsum above dark brown to black lateral stripe tan to light brown, uniformly pigmented, typically without dark reticulations; midline of dorsum without dark saddles or if present confined to midline of dorsum; scales present on nape, cheeks, opercles, and breast. Description. Percina kusha is a moderately small species of Percina; the largest specimen examined is a 65 mm SL male. Typical shape of the head and body illustrated in Figure 2a. Frequency distribution of scale, fin ray and vertebral counts given in Tables 1-8. Degree of nape squamation presented in Table 9 and the posterior extent of development of pored lateral line scales given in Table 10. Proportional measurements presented in Table 11. Body moderately elongate, slender, snout moderately long, about equal in length to the orbit, and frenum well-developed. Preopercular margin entire and branchiostegal membranes separate or very narrowly joined. Total lateral line scales 58-73, usually 65-70; transverse scale rows 14-18, usually 17 in the Conasauga River population and 15 in the Etowah River population; caudal peduncle scales 18-25, usually 22-24 in the Conasauga River population and 19-21 in the Etowah River population; dorsal spines 11-15, usually 12-14; dorsal soft rays 9-11, usually 10; anal soft rays 6-9, usually 8; pectoral rays 13-14, usually 14; vertebrae 41-43, usually 42. Lateral line usually complete but some individuals with 1-2 unpored scales anterior to posterior edge of hypural plate or a pored scale on the caudal fin base (Table 10). Scales present on the opercles and upper three quarters of the cheek. Nape completely scaled, occasionally with some embedded scales anteriorly. Scales on the anterior portion of breast and prepectoral area usually embedded. Belly typically scaled with the exception of the area immediately posterior of the base of the pelvic fins. Males with a row of enlarged, modified ctenoid scales present on midline of belly, but usually less well-developed or absent just posterior to pelvic fin base. There are usually 1-2 modified scales present between the base of pelvic fins. Occasionally an individual will have up to four modified scales but only one or two are large and well-developed. The large, modified breast scale at the anterior junction of the pelvic girdle of some Percina is absent in P. kusha. In females the row of scales along the midline of the belly is greatly reduced or absent but there are usually one or two modified scales present between the base of the pelvic fins. Breeding tubercles are absent but some males have thickened ridges along margin of anal fin rays. Live coloration of adult females and males is similar but females typically lack the dusky ground color present in males. Sides of the body with 8-11 elongate oval blotches which are connected forming a uniformly dark lateral stripe with undulating margins. In some individuals the dark blotches are discrete but connected by lighter brown pigment. Lateral blotches are lighter in color and less connected in juveniles. Anteriorly the lateral stripe is continuous with the postorbital and preorbital bars. Posteriorly the lateral stripe terminates on the base of the caudal fin in a somewhat quadrate-shaped blotch that is equal or slightly lighter in color to the lateral stripe. It is usually centered just below the midline of the caudal fin. The blotches on the upper and lower caudal fin base vary in size and intensity. In most individuals the upper blotch is larger and more intense. The lower blotch is often indistinct or merged with the basicaudal blotch. Above the dark, undulating lateral stripe, the dorsum is typically tan to light brown without any blotches, reticulations, bars or saddles. In some individuals thin, elongate blotches may be present along the midline of the dorsum and an adjacent scale row on each side, usually under the dorsal fins. Occasionally an individual may have a dusky, thin line, one or two scale rows wide, just above the lateral stripe. This line is often interrupted forming a series of long dashes above the lateral stripe. Intensity of the thin line of dark pigment varies but is always darker than the adjacent dorsal pigmentation but lighter than the lateral stripe. Any dark pigment present above the lateral blotches is most prevalent in juveniles. Below the lateral stripe the body is uniformly pigmented and lacks dark spots, blotches or reticulations. It is typically dusky on breeding males but always uniformly pigmented. Breast and lower side of head are white to cream colored but may be dusky in breeding males. Some individuals have a few melanophores on the anterior base of the pectoral fin. Suborbital bar is typically absent, but some breeding males have an irregular shaped cluster of melanophores on the midventral margin of the orbit. Pigmentation of the spinous dorsal fin of males consists of a broad, dusky basal band, almost black in breeding males, an unpigmented submarginal band, and a thin, dusky marginal band. Dusky pigment in dorsal fin is usually darker posteriorly. Pigmentation of the soft dorsal and caudal fins is variable but typically there are dusky marginal and basal bands with an unpigmented band in between. The pelvic, pectoral, and anal fins are usually clear except dusky in breeding males. Coloration of non-spawning males and females is yellowish above and below the dark bluish-black lateral stripe. Breast and belly are white to cream color. Top of head and snout variously mottled with yellowishorange color. Dorsal, pectoral, and caudal fins pale yellowish and the pelvic and anal fins colorless. Variation in the scale counts (Tables 1-3) between the Conasauga and Etowah River populations of Percina kusha was unexpected considering the proximity of the two drainages (Fig. 3). There is almost no overlap in number of scale rows from the soft dorsal origin to the anal fin base and the caudal peduncle scale rows. There is also a modal difference in the degree of nape squamation between the two drainages (Table 9). Analysis of mitochondrial DNA revealed very little differentiation between these populations, although they were recovered as reciprocally monophyletic groups (discussed below). A higher number of lateral line scales and vertebrae were reported for P. lenticula populations in the Etowah River drainage compared to the Coosa and Cahaba River populations (Richards & Knapp 1964; Suttkus & Ramsey 1967). This variation may be the result of habitat differences between the Etowah and Conasauga River drainages. Most of the Etowah drainage is in the Piedmont physiographic province, and most of the Conasauga is in the Valley and Ridge province (Fig. 3). The presence and distribution of other endemic species in the Etowah drainage (e.g. Etheostoma etowahae, E. scotti, and Cambarus fasciatus) suggests that the divide between the physiographic provinces has been an effective barrier to gene flow in some taxa, and may be responsible for speciation within the Piedmont portion of the Etowah River system. Distribution. Percina kusha is restricted to the headwaters of the Coosa River in Georgia and Tennessee (Fig. 3). It occurs in the main channel of the upper reaches of the Conasauga River in Murray and Whitfield counties, Georgia, and Bradley and Polk counties, Tennessee. It is also known from short reaches of three tributaries to the Conasauga River: Holly Creek, Murray County, Georgia; and Ball Play and Minnewauga creeks, Polk County, Tennessee. In the Etowah River it occurs in the main channel in Dawson and Lumpkin counties, Georgia, and in several tributaries: Amicalola, Little Amicalola, Cochran and Shoal creeks, Dawson County, Georgia. Ecology. Percina kusha inhabits small rivers and lower reaches of tributary creeks with good water quality. These streams are characterized by moderate gradient where the substrate consists of sand, gravel, cobble and bedrock. Percina kusha is usually found in flowing pools and backwaters adjacent to runs, where it has been observed hovering over or resting on submerged structures such woody debris, stems of Justicia americana, and large cobble. During winter we have observed P. kusha among leaf packs in pools. Frequent associates of P. kusha are Campostoma oligolepis, Cyprinella trichroistia, C. venusta, Etheostoma stigmaeum, Hypentelium etowanum, Notropis xaenocephalus, P. kathae, P. nigrofasciata and P. palmaris. Etnier & Starnes (1993) provide information on feeding and reproduction of the Conasauga River population. Johnson et al. (2002) conducted a study of seasonal spawning habitat utilization in the Conasauga River in Murray County, Georgia, during 1999 and 2000. There is no information available on the ecology and biology of the Etowah River population of P. kusha. Conservation status. Etnier & Starnes (1991) considered the conservation status of Percina kusha to be endangered, like two other Percina species endemic to the upper Coosa River system, P. antesella and P. jenkinsi. In a review of conservation status of fishes in Georgia, Freeman (1999) assigned a status of rare (a species in need of protection because of its scarcity) to populations in Georgia. Warren et al. (2000) and Freeman et al. (2005) both regarded P. kusha as vulnerable (any taxon that may become endangered or threatened by relatively minor disturbance to its habitat). Based on our sampling and snorkeling observations, P. kusha appears to be a species that naturally occurs in low abundance, at least when compared to sympatric congeners such as P. nigrofasciata and P. palmaris. We do not know, however, what the actual range of the species was prior to European colonization. Its association with slow-flowing habitats suggests P. kusha could have occurred throughout the Conasauga and Etowah rivers, and possibly in the geographically intermediate Coosawattee River, below the gorge now impounded by Carters Dam and Reservoir (Fig. 3). Considering its very limited distribution in portions of two small rivers and threats to its habitat from municipal and industrial development and forestry and agriculture activities we consider P. kusha to be endangered. Etymology. The specific name, kusha, is the Choctaw Indian name for cane or canebrake and is the origin of the name of the Coosa River (Foscue 1989). The common name, Bridled Darter, is in reference to the preorbital and postorbital bars that are continuous with the lateral stripe, thus resembling an equestrian bridle and reins. Comparison with congeners. In the headwaters of the Coosa River in northwest Georgia, populations of Percina kusha are sympatric and occasionally syntopic with eight species of Percina: P. antesella, P. aurolineata, P. jenkinsi, P. kathae, P. lenticula, P. nigrofasciata, P. palmaris and P. shumardi. The dorsum of most individuals of P. kusha are uniformly pigmented above the dark brown to black lateral band which distinguishes it from all eight species of Percina which typically have well-developed saddles that extend across the back, mid-dorsal blotches, lateral and dorsolateral bars or a dorsolateral stripe (above dark lateral stripe). Morphologically, P. kusha is easily distinguished from the logperches, P. jenkinsi and P. kathae, which have a conical snout that projects beyond the anterior margin of the upper jaw. It differs from both P. antesella and P. shumardi in having a well-developed frenum and a row of modified scales along the midline of the belly of males. Percina kusha also lacks the elongate anal fin and breeding tubercles, which are well-developed on the anal, caudal, and pelvic fins, of breeding male P. antesella and P. shumardi. Percina kusha has very narrowly joined to overlapping gill membranes which differs from the more broadly joined membranes present in P. lenticula and P. nigrofasciata. The lateral blotches of P. lenticula and P. nigrofasciata are also more vertically elongate than those of P. kusha. The remaining species, P. aurolineata, differs in having a serrate preopercle and from 1-3 pored lateral line scales on the base of the caudal fin.Published as part of James D. Williams, David A.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Teaching India–Pakistan Relations
Get PDFThe rivalry between India and Pakistan began on British withdrawal from the British Indian Empire in 1947, and with the sudden partition of India immediately afterwards. It has proven remarkably resilient. While the countries share a long history and have considerable social–cultural affinity, relations since Partition have been marked by three wars, constant border skirmishes and a deep distrust that permeates both societies. In each, teaching about those relations is weighted with political and cultural significance, and research shows that curriculums have been used to shape the mindset of new generations with regard to their neighbouring state.
This book explores the attitudes and pedagogical
decision-making of teachers in India and Pakistan when teaching India–Pakistan relations. Situating teachers in the context of reformed textbooks and curriculums in
both countries that explicitly advocate
critical thinking and social cohesion, Kusha Anand
explores how far teachers have enacted these changes in their classrooms. Based on data collected from teachers via
semi-structured interviews and classroom observations in India and Pakistan she
argues that, despite whole-nation policies and texts, teaching of India–Pakistan
relations is dependent on the socio-economic status of schools. While there is
progress towards the stated goals, teachers in both countries face pressures from
the interests of school and state, and often miss opportunities to engage with
multiple perspectives and stereotypes in their classrooms
Extraction and Characterization of Lignocellulosic Fibers from Girardinia Bullosa (Steudel) Wedd. (Ethiopian Kusha Plant)
No full textCurrently, eco-friendly products have been given great attention as the world is being polluted severely by non-biodegradable products and by-products. Different textile products have their own share in affecting the environment. This research is focused on exploring alternative bast fiber products to support the supply chain and to assess the possibility of using this fiber as a substitute to already available bast fibers. Kusha fiber was extracted and optimized from Ethiopian kusha plant stem – Girardinia bullosa (Steudel) wedd. – using caustic soda solution by varying the concentration, temperature, and time using design expert 6.0.10, quadratic model software. Tensile property, chemical composition, X-ray diffractometer (XRD), Fourier-transform-infrared spectroscopy (FTIR), fiber morphology, and thermogravimetric analysis (TGA) of the fiber were determined. Fiber characterization showed its tensile strength, and the cellulose content was equivalent to or even better than other bast fibers. Morphology of the fiber was similar to that of typical cotton with visible lumen and a slightly flat surface. Therefore, this new extracted fiber has a great potential to be used for different applications such as fiber-reinforced composites, textile furnishing, apparel, and nanocellulose extraction
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
