Stability and Equilibrium Analysis of Laneless Traffic with Local Control Laws
In this paper, a new model for traffic on roads with multiple lanes is
developed, where the vehicles do not adhere to a lane discipline. Assuming
identical vehicles, the dynamics is split along two independent directions: the
Y-axis representing the direction of motion and the X-axis representing the
lateral or the direction perpendicular to the direction of motion. Different
influence graphs are used to model the interaction between the vehicles in
these two directions. The instantaneous accelerations of each car, in both X
and Y directions, are functions of the measurements from the neighbouring cars
according to these influence graphs. The stability and equilibrium spacings of
the car formation is analyzed for usual traffic situations such as steady flow,
obstacles, lane changing and rogue drivers arbitrarily changing positions
inside the formation. Conditions are derived under which the formation
maintains stability and the desired intercar spacing for each of these traffic
events. Simulations for some of these scenarios are included.Comment: 8 page
Subdued Voices: Women Characters and their Author in Inside the Haveli
Rama Mehta is an eminent novelist who contributed significantly to Indian English fiction by bringing female issues to the fore through her exemplary novel, Inside the Haveli. The novel shows a predominant concern with the subjugating condition of women characters shackled in the Indian patriarchal structure and brings, particularly, into light the repressed state of female characters and the elements that determine their submission. Simultaneously, based on the incident, the novel reveals silence and submission on the part of the novelist as well. Nevertheless, the work seems stifled when dealing with women's issues; its movements are confusing, contradicting and oscillating. The characters and their author appear tense under pressure showing a disinclination to adopt a bold stance. This cramped and oscillating situation speaks of their helplessness and repressed situation
The Theme of Protest and Freedom in Cry, the Peacock
The conflict between social institutions and individuals is a complex and perplexing issue for many scholars. While reflecting on this issue, some scholars propagate the privilege to individuality, the others to the social institutions. Many scholars consider it as a matter of mutual coordination and interest. The need for a relative space for an individual and the requirement of the social institutions for regulating control over an individual’s uncensored wills are equally important. However, safeguarding or maintaining the margins of both entities is complex work. Regulating uncensored wills or reducing excessive encroachment of institutional authorities is a difficult task; it needs to be addressed with a scientific approach. The Indian social system is conservative and has been maintaining its dominance over the women’s class from the time unknown. The society, after allotting all the privileges to male members, refuses to consider women as individuals, having space and freedom. It expects women to be timid, docile, submissive and obedient. As a result, they feel tyrannized and experience untold sufferings. When the patriarchal system becomes over oppressive, it leads women to absolute confinement; the life of complete closure is highly disappointing and frustrating. The forces that obliterate their rights include gender discrimination, marriage-system, orthodox traditions, customs, rituals and class status. A woman is born with a destitute to experience a collision with the subjugating elements in her life and while wrestling against it she has little success. She goes through a perpetual war against the controlling institution while creating a space for her individuality and freedom. The factors like these rob women characters of happiness and advantages and lead women to live an insignificant life, full of suffering
Influencia del procedimiento de extracción en la actividad antioxidante de extractos de semilla de lenteja en un sistema modelo β-caroteno linoleato
Phenolic compounds were extracted from lentil seeds using three solvent systems: 80% (v/v) acetone, 80% (v/v) methanol, and 80% (v/v) ethanol. Each extract was subsequently separated into two fractions by chromatoghraphy on a column with Toyo Pearl HW-40 using water (fraction I) and methanol (fraction II) for elution. Antioxidative activity of extracts and their respective fractions were examined in a β-carotene-linoleate model system. All three extracts exhibited similar antioxidant activity. Considering the level of phenolic compounds in extracts it seems that phenolic compounds from the acetone extract were less active than those from either the methanolic and ethanolic ones. Because the content of phenolics was about 16-fold lower in fraction I of the methanolic and ethanolic extracts compared to fraction II, the phenolics in fraction I of the methanol and ethanol extracts from lentil seeds are much more active than these in fraction II. A stronger antioxidant activity of fraction I from the acetone extract compared to the crude acetone extract was observed during the latter incubation stage. The reason was a relatively high level of phenolic compounds in this fraction. UV spectra confirmed that the phenolic compounds from the acetone extract were different compared to methanolic and ethanolic extracts.Los compuestos fenólicos fueron extraídos de semillas de lenteja usando tres sistemas de disolventes: acetona del 80% (v/v), metanol del 80% (v/v), y etanol del 80% (v/v). Cada extracto fue separado posteriormente en dos fracciones por cromatografía en columna con Toyo Pearl HW-40 usando agua (fracción I) y metanol (fracción II) para la elución. La actividad antioxidante de los extractos y de sus fracciones respectivas fueron examinadas en un sistema modelo β-caroteno-linoleato. Los tres extractos exhibieron actividad antioxidante similar. Atendiendo al nivel de compuestos fenólicos en los extractos parece que los compuestos del extracto acetónico eran menos activos que los metanólicos y etanólicos. Debido a que el contenido de fenoles era aproximadamente 16 veces más bajo en la fracción I de los extractos metanólico y etanólico comparado con la fracción II, los fenoles en la fracción I de los extractos del metanol y del etanol de las semillas de lenteja son mucho más activos que éstos en la fracción II. Una actividad antioxidante más fuerte de la fracción I del extracto acetónico comparado con el extracto acetónico crudo fue observada durante el posterior periodo de incubación. La razón fué el relativamente alto nivel de compuestos fenólicos en esta fracción. El espectro UV confirmó que los compuestos fenólicos del extracto de acetona fueron diferentes comparados con los extractos metanólicos y etanólicos
Hardness Phenomenon in Beach Pea (Lethyrus Maritimus L.)
Beach pea is mostly grown on seashores and it contains higher amount of protein than other legumes. However, the pea has several undesirable attributes, such as long cooking time and hard to germinate (imbibitions) that limited its use as food. The present investigation aimed to study the physico-chemical properties, cooking characteristics and hull crude fibre structure of beach pea as compare to other similar legumes. Standard methods of processing pulses were used for present study. Beach pea seeds contained very low grain weight, density, hydration capacity, hydration index, swelling capacity and swelling index than the green pea and field pea. Beach pea had higher amount of crude protein, ash, crude fibre and polyphenols, but lower in starch content than the green pea and field pea. Without any treatment to beach pea seeds the water uptake capacity was very low. Mechanical treatment to beach pea seeds increasedthe water uptake percentage. The recovery of hull was 3 to 6 times higher in beach pea than that of green pea and field pea. The crude protein content in beach pea hull was 2-5% higher than others. The beach pea hull, dhal and whole seeds were good source of macro- and micro- minerals than that of the other two peas. The electron microscopic structure of beach pea hull crude fibre showed a very close and compact structure than green pea and field pea hull crude fibre structure. Lowering the hardness of beach pea seeds with mechanical or chemical treatments will give more scope for their utilization in the human nutrition
Nutritional and Roti Quality of Sorghum Genotypes
Sorghum grains are mostly used for the roti preparation. The M 35-1 (Maldhandi) a sorghum cultivar is known for its good quality of roti due to having pearly white grain color, its flour having higher water holding capacity, and good organoleptic taste. However, this cultivar is low yielder. To evolve sorghum high yielding genotype coupled with this good roti qualities, systematic breeding program was planned and executed to overcome this problem. Twenty local land races, 92 genotypes, and seven improved cultivars of sorghum along with check M 35-1 were studied for various nutritional quality parameters, with special reference to the roti quality. Considering nutritional quality and organoleptic evaluation parameters studied for roti quality, the local land races viz., RSLG 428-1, RSLG 1238, RSLG 1275 and the genotypes viz., RSV 290, RSV 292, RSV 858, RSV 859, RSV 861, RSV 868, RSV 894, RSV 985, RSV 992, RSV 995, RSV 999 were found to be promising for protein, sugar, water absorption, and soluble protein content. Therefore, they can be used for further improvement in nutritional quality through breeding program. Among the improved cultivars, Phule Vasudha (RSV 423), CSV 22, and Phule Chitra (SPV 1546) werefound to be most promising for roti quality. The maximum score for overall acceptability was found for Phule Vasudha followed by Phule Anuradha (RSV 458), Phule Yeshoda (RSLG 262), and Phule Maulee (CSV 216)

Transforaminal percutaneous endoscopic lumbar discectomy versus microdiscectomy: an Indian rural experience
Background: The objective of the study was to compare surgical outcome of micro-discectomy with transforaminal percutaneous endoscopic lumbar discectomy for single level lumbar disc herniation in Indian rural population.Methods: Retrospective comparative study was designed during the period of October 2012 to June 2015, patients in the age group of 22-75 years with unremitting sciatica with/without back pain, and/or a neurological deficit that correlated with appropriate level and side of neural compression as revealed on MRI, with single level lumbar disc herniation who underwent either microdiscectomy or TPELD were included in the study. Patients were assessed on visual analogue scale (VAS) for back and leg pain, modified macnabs criteria, the Oswestry Disability Index (ODI).Results: Group I (MD) included 44 patients and Group II (TPELD) included 20 patients. Significant improvement was seen in claudication symptom post-operatively in both MD and TPELD. Mean operating time was significantly shorter in MD group (1.11 hrs vs. 1.32 hrs; p<0.01). According to modified MacNab's criteria, outcome were excellent (81.8%), good (9.09%) and fair (9.09%) in MD. Similarly, in TPELD, 80%, 15% and 5% patients had excellent, good and fair outcome respectively. In both groups, no one had a poor outcome. Thus, overall success rate was 100% in the study.Conclusions: TPELD and MD have comparable post-operative outcome in most of the efficacy parameters in Indian rural patients undergoing treatment of single level lumbar disc herniation. Additionally, TPELD offers distinct advantages such as performed under local anaesthesia, preservation of structure, lesser post-operative pain and early mobilization and discharge from hospital
