Authors: Niroula B. , Parajuli D. , Jha S.
Published: January 2010

All the freshly collected mature seeds of M. pudica were greenish in colour, whereas 7 year old stored seeds were a mixture of greenish and brownish seeds. The greenish seeds had hard seed coat and acid treated as well as sand rubbing for 6-10 min greatly enhanced their germination percentage. The brownish seeds were simply the deteriorated form of greenish seeds. Leaves and pods had higher contribution to total plant dry weight in ungrazed field and in pot-cultured plants clipped a month before flowering. The young shoots of the plant had 18.9% crude protein, 0.46% phosphorus and 25.4% crude fibre on dry weight basis.Key words: Hard seed coat, Mimosa pudica, scarification, dry matter productionDOI: 10.3126/on.v7i1.2568Our Nature (2009) 7:177-181

Authors: Alom Md Mashudul , Begum Noorzahan , Ferdousi Sultana , Begum Shelina , Ali Taskina
Published: January 2010

Background: Cardiac autonomic nervous activities (CANA) deteriorate with age, obesity, sedentary life style and in various cardiac and noncardiac disease conditions. Regular physical exercise may improve CANA in health and diseases. Power spectral analysis (PSA) of Heart rate variability (HRV) is one of the most promising newer techniques to quantify CANA. Objective: To analyze HRV by Power Spectral method in order to find out the influence of regular physical exercise on CANA in male adolescent athletes. Method: This cross sectional study was carried out on 62 adolescent male athletes aged 12-18 years (group B), in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University from 1st July 2007 to 30th June 2008. For comparison, 30 age, sex, BMI and socioeconomic condition matched apparently healthy sedentary subjects (group A) were also studied. The study subjects were selected from the BKSP (Bangladesh Krira Shikka Prothistan, Savar, Dhaka) and the control from a residential school of Dhaka city.Power spectral measures of HRV including Total Power (TP), Very Low Frequency Power (VLF) Low Frequency (LF), High Frequency (HF) LF/HF were measured by a Polygraph. For statistical analysis, Independent-Sample t-test was used. Results: Total power, HFnu power and the VLF, LF, HF were significantly (P<0.001) higher and LFnu power and the LF/HF ratio were significantly (P<0.001) lower in athletes than those of nonathletes which indicate higher cardiac parasympathetic and lower sympathetic activity in athletes. Conclusion: Cardiac Autonomic regulation with increased parasympathetic and decreased sympathetic modulation may occur with in athletes engaged with regular physical exercise.

Authors: Kabir Md Rasel , Begum Noorzahan , Ferdousi Sultana , Begum Selina , Ali Taskina
Published: January 2010

Background: Hyperthyroidism is associated with altered cardiac autonomic nervous activity (CANA). Heart Rate Variability (HRV) analysis is a promising technique to quantify CANA and therefore can be done in hyperthyroidism. Objective: To observe the HRV parameters in patients with hyperthyroidism to find out the influence of excess thyroid hormone on cardiac autonomic nervous activities. Method: The cross sectional study was carried out on 60 hyperthyroid patients (groupB) aged 30-50 years in the Department of Physiology, BSMMU, Dhaka from 1st July 2007 to 30th June 2008. Age and sex matched 20 apparently healthy euthyroids were also studied for comparison (group A). On the basis of treatment, they were further divided into group B1 consisting of 30 untreated newly diagnosed patients and group B2 consisting of 30 hyperthyroid patients treated with antithyroid drugs for at least 2 months. The patients were selected from the Out Patient Department of Endocrinology, BSMMU, Dhaka. To assess thyroid status, serum TSH and serum FT4 levels were measured by AxSym system and time domain measures of HRV such as mean R-R interval, mean heart rate, SDNN and RMSSD were assessed from 5 minute (short term) ECG recording by a polygraph. For statistical analysis Mann-Whitney U test was done. Results: Mean R-R interval was significantly (P<0.001) lower but mean heart rate was significantly (P<0.001) higher in untreated patients than those of treated and euthyroids subjects. These values were found almost similar when compared between euthyroids and treated hyperthyroids. Similarly SDNN and RMSSD were significantly lower in untreated hyperthyroids than both euthyroids (P<0.001) and treated hyperthyroids (P<0.01). Conclusion: This study concluded that decreased vagal modulation on heart rate may occur in hyperthyroidism, which may be restored following adequate treatment of the disease.

Background: To enhance successful communication medical teachers are increasingly using different visual aids. Objective: To determine medical students perception of different visual aids like black board (BB), over head projector transparencies (OHPT) and, LCD and to generate recommendations for their optimal use. Methods: A questionnaire based study was carried out among first year MBBS students of Government Medical College, Kota, India. The survey was undertaken among 84 Medical students of first year MBBS of batch 2008 after exposing them to different visual aids like BB, OHPT and LCD in Physiology lectures. A few lectures were absolutely on BB, and some were on OHPT and on LCD. Few classes were taken with mixed visual aids. Students were exposed for such visual aids for one year and then they were requested to complete a questionnaire. Data were statistically analyzed by One Sample Chi-square test. Results: 55 (65.48%) students rated chalk & black board as best visual aids in understanding the topic better as compared to OHPT and LCD (P<0.01). 47 (55.95%) students have good learning experience with black board teaching and it is best mode to note down important points. 56 (66.66%) students favored LCD as more interesting and interactive visual aids (P<0.01). It also complete the lecture faster which was advantageous for 69 (82.17%) students. 77 (91.66%) students wanted mixing of different visual aids (P<0.01). Mostly (75%) do not find any difficulty in switching from one mode to another. No significant gender difference was observed. Conclusion: To improve students learning medical teachers should match the lectures with preferred visual aids. It will maintain interest and enthusiasm among pupil.

Diversity: A Philosophical Perspective
Authors: Sarkar Sahotra
Published: January 2010

In recent years, diversity, whether it be ecological, biological, cultural, or linguistic diversity, has emerged as a major cultural value. This paper analyzes whether a single concept of diversity can underwrite discussions of diversity in different disciplines. More importantly, it analyzes the normative justification for the endorsement of diversity as a goal in all contexts. It concludes that no more than a relatively trivial concept of diversity as richness is common to all contexts. Moreover, there is no universal justification for the endorsement of diversity. Arguments to justify the protection of diversity must be tailored to individual contexts.
The Quantum-Classical Transition as an Information Flow
Authors: Kowalski Andres M. , Martin Maria T. , Zunino Luciano , Plastino Angelo , Casas Montserrat
Published: January 2010

We investigate the classical limit of the semiclassical evolution with reference to a well-known model that represents the interaction between matter and a given field. This is done by recourse to a special statistical quantifier called the “symbolic transfer entropy”. We encounter that the quantum-classical transition gets thereby described as the sign-reversal of the dominating direction of the information flow between classical and quantal variables.
Photoresponsive Block Copolymers Containing Azobenzenes and Other Chromophores
Authors: Yu Haifeng , Kobayashi Takaomi
Published: January 2010

Photoresponsive block copolymers (PRBCs) containing azobenzenes and other chromophores can be easily prepared by controlled polymerization. Their photoresponsive behaviors are generally based on photoisomerization, photocrosslinking, photoalignment and photoinduced cooperative motions. When the photoactive block forms mesogenic phases upon microphase separation of PRBCs, supramolecular cooperative motion in liquid-crystalline PRBCs enables them to self-organize into hierarchical structures with photoresponsive features. This offers novel opportunities to photocontrol microphase-separated nanostructures of well-defined PRBCs and extends their diverse applications in holograms, nanotemplates, photodeformed devices and microporous films.
Analysis of Large Scale Spatial Variability of Soil Moisture Using a Geostatistical Method
Authors: Lakhankar Tarendra , Jones Andrew S. , Combs Cynthia L. , Sengupta Manajit , Vonder Haar Thomas H. , Khanbilvardi Reza
Published: January 2010

Spatial and temporal soil moisture dynamics are critically needed to improve the parameterization for hydrological and meteorological modeling processes. This study evaluates the statistical spatial structure of large-scale observed and simulated estimates of soil moisture under pre- and post-precipitation event conditions. This large scale variability is a crucial in calibration and validation of large-scale satellite based data assimilation systems. Spatial analysis using geostatistical approaches was used to validate modeled soil moisture by the Agriculture Meteorological (AGRMET) model using in situ measurements of soil moisture from a state-wide environmental monitoring network (Oklahoma Mesonet). The results show that AGRMET data produces larger spatial decorrelation compared to in situ based soil moisture data. The precipitation storms drive the soil moisture spatial structures at large scale, found smaller decorrelation length after precipitation. This study also evaluates the geostatistical approach for mitigation for quality control issues within in situ soil moisture network to estimates at soil moisture at unsampled stations.

A Fair Accord: Cradle to Cradle as a Design Theory Measured against John Rawls’ Theory of Justice and Immanuel Kant’s Categorical Imperative
Authors: Voorthuis Jacob , Gijbels Cyrille
Published: January 2010

This essay explores a specific aspect of the role of attitude in design. The design of the built environment requires us constantly to make aesthetic and ethical judgments; every design decision has to be satisfactorily justified. Surprisingly perhaps, this requires a clear concept of justice against which a design can be grounded. Aesthetic concerns about quality spill into ethical concerns about the rightness of a decision and vice versa. This essay discusses a simple but crucial question: if a designer is aware of Cradle to Cradle as a theory of design but fails to act according to its principles, is it then possible to justify the resultant design? In other words, is Cradle to Cradle as a design theory that most rare of transcendental notions: a Categorical Imperative? Why might it be useful to describe it as such? Does the fact that we do not yet know how to redesign most products and processes according to its principles disqualify the theory? Does a dismissal of the Cradle to Cradle theory inevitably lead to an unfair society? These are serious questions, with interesting answers and far reaching implications for the way we think about design. First we shall explain what Cradle to Cradle means and how it distinguishes itself from other theories of sustainability. Then we shall put that explanation in the context of two ethical theories, first of all John Rawls’ Theory of Justice and second Immanuel Kant’s concept of the Categorical Imperative. After that we shall note a few problems concerning Cradle to Cradle design theory and put those into perspective. This will lead to an important attitudinal conclusion, namely that Cradle to Cradle can legitimately be described as one of those extremely rare cases which deserves universal applicability. We will offer a two-pronged strategy as to how to proceed.

Professional Development for Night Shift Nurses
Authors: Mayes Pamela , Schott-Baer Darlene
Published: January 2010

This article examines the teaching-learning experiences of registered nurses who work exclusively at night. Various teaching strategies that are useful in advancing professional development activities for registered nurses who work at night are proposed. A literature review of nighttime learning opportunities and teaching strategies useful for nighttime education is presented. Findings indicate that nurses who work at night are motivated to learn, but have fewer opportunities and less access to programs than nurses who work during the day. These barriers can be reduced by enhancing nighttime education programs and using teaching methods appropriate to the night shift. An example of a successful cardiac arrest in-service offered during the nighttime hours is described.

Retaining the Experts: Aging Nurses in Mental Health
Authors: Sorrell Jeanne M.
Published: January 2010

The aging of the nursing workforce has contributed to the critical shortage of nurses. There is a consistent pattern of nurses leaving hospital settings as they age and leaving the workforce entirely after age 50. Few data are available on how this may affect quality of care in mental health services in the future. Research is needed to better understand the relationship between workplace variables and older workers' health, safety, and satisfaction, so that aging nurses in mental health may extend their working life and continue sharing their expertise that has been developed over many years.
REVIEW OF THE CANADIAN SPECIES OF THE DIPTEROUS FAMILY BLEPHARICERIDAE

Published: January 2010

The present paper is an attempt to review and bring up to date our knowledge of the Canadian species of net-winged Midges or Blephariceridae. Since the publication in 1903 of Kellogg's “Net-Winged Midges of North America,” several new species have been added to our list and additional records have come to hand thus increasing our knowledge of the distribution of several species; also certain generic changes seem advisable and it is hoped that the present paper will serve to facilitate the identification of our Canadian species.

In connection with the investigative work on Trachychele damage to western red cedar, it became expedient to make a study of the life history of the species, Trachychele blondeli Mars., which has become very troublesome to pole operators on the Coast of British Columbia. Accordingly a study of the life history was started by the writer in 1925. In the fall of that year and during the spring and summer of 1926, the seasonal history was studied and observations were made on emergence, egg laying, and breeding habits. The exact length of time spent in the larval state is still uncertain.

NOTES ON THE OCCURENCE OF AEDES (OCHLEROTATUS) NEARCTICUS DYAR IN THE ROCKY MOUNTAINS PARK, ALBERTA. (CULICIDAE DIPT.)
Authors: Hearle Eric
Published: January 2010

One of the more interesting details of a recent investigation of the mosquitoes of the Rocky Mountains Park, Alberta, was the finding of Aedes nearcticus Dyar—a mosquito hitherto considered to be restricted to the Arctic regions of Europe and North America. A few specimens were first taken at Lake Louise in 1921, when Mr. Arthur Gibson, the Dominion Entomologist, and the writer made a brief survey of mosquito conditions. In 1922 further specimens came to hand through the kindness of Mr. N. B. Sanson who sent the writer living larvae collected at Simpson's Summit at about 7000 feet. Adults were successfully reared from these. During 1924 and 1925 a number of trips were made by the writer and his assistant, Mr. A. G. Mail, to secure data on this interesting species, and several hundred specimens of larvae, and both sexes of adults were taken.

Some specimens agree very well with the characters given in Rohwer's key while others show a complete intergradation of characters and cannot be associated with either form.

THE FERN-FEEDING SPECIES OF PAPAIPEMA; NO. 25 (LEPIDOP TERA)
Authors: Bird Henry
Published: January 2010

That four species of Papaipema, Papaipema stenoscelis Dyar, P. speciosima G. & R., P. inquaesita G. & R. and P. pterisii Bird, persist in making a food choice among the Cryptogams, those plants whose ancestry dates so far back in the floral phylum, might suggest that this quartet should show evidence of being the fore-runners of their generic complex.
LEPIDOPTERA REARED IN MANITOBA FROM POISON IVY
Authors: Criddle Norman
Published: January 2010

Among plants that possess toxic properties few are so well known, or so much dreaded, in North America, as poison ivy (Rhus toxicodendron). The plant is distasteful to nearly all herbivorous animals, though its berries are eaten by a few rodents and birds. On the whole it is permitted to flourish unmolested and it has managed to enlist the cooperation of several birds as aids in the distribution of its seeds. The immunity enjoyed by this plant from larger creatures does not, however, apply to the smaller forms of life and among its insect enemies Coleoptera, Diptera and Lepidoptera are representd. A study of the lepidopterous insects found feeding upon poison ivy was begun some years ago and a number of species were reared. The notes relating to these have now been brought together under the above heading.
LIGHT TRAPS AS INDICATORS OF CUTWORM MOTH POPULATION
Authors: Cook William C.
Published: January 2010

Light traps have long been used to indicate cutworm moth population, but a survey of the literature reveals no instance in which light trap catches have been compared with any other source of information regarding the moth population. It has apparently been assumed by all workers, the writer included, that a light trap record furnished a reliable random sample of the population. Certain data have recently accumulated, horvever, which make it desirable to question this assumption, and some of these data will be presented here.

THE PALE WESTERN CUTWORM (POROSAGROTIS ORTHOGONIA) (LEPID.)
Authors: Ainslie C. N.
Published: January 2010

This insect was first known in 1876, near Fremont, Nebraska, where it was taken and named. It then disappeared from that vicinity, its disappearance caused, it has been surmised, by the severe grasshopper invasions of 1875 and 1876, and was unknown until 1911 when it was reported as doing much injury to small grains in Alberta, Canada. During the succeeding years it appears to have moved south, or, possibly, to have multiplied locally, and in 1919 it was doing noticeable damage to crops in eastern Montana and western North Dakota. Its chief injury was to wheat and corn but it also attacked rye, barley, oats and, to a limited extent, flax and millet, also potatoes.
TWO NEW SPECIES OF BOLBOCEROSOMA WITH NOTES ON THE HABITS AND GENITALIA OF OTHER SPECIES.
Authors: Brown W. J.
Published: January 2010

The purpose of the present paper is to describe two new species of Bolbocerosoma and to figure the genitalia of the North American species of this genus. It therefore supplements the paper of Dawson and McColloch (Can. Ent., LVI, 9-15).
SOME NEW GENERA AND SPECIES OF N. A. DERBIDAE WITH NOTES ON OTHERS (FULGORIDAE)
Authors: Ball E. D.
Published: January 2010

Otiocerus kirbyi Fh. is unknown to the writer. It would fall under CC. of Group II by description. It may well be a pale form of one of these species. The species found in collections under the name of signoreti Fh. is undoubtedly reaumuri Kby. Metcalf separated the latter as “without” the five spots ignoring the fact that Kirby specially describes them. In the explanation of Plate 40 Metcalf has reversed the name of O. degeeri, and coqueberti. The head of the example of the latter species must have been distorted or out of focus as in nature the apex is but little less than a right angle.
NOTES ON THE BIOLOGY OF STAGMOMANTIS CAROLINA. (ORTHOPTERA, MANTIDAE)
Authors: Roberts R. A.
Published: January 2010

My first work with the comrnon mantid, Stagmomantis carolina John began accidentally. One afternoon in early May, at Dallas, Texas, a number of egg masses of the mantid were placed on my desk for inspection. In looking them over I noticed that several had been parasitized and that in others the nymphs had already emerged. I paid very little attention to the unhatched eggs. The next morning May 7, 1927, my desk was covered with numbers of ungainly little brownish green creatures that raced madly about and made frantic efforts to hide behind books and papers. Thirty of these mantid nymphs were captured and placed under a glass lantern globe. A week later a second egg mass hatched. These two broods, together with a stray nymph I found, furnished me with material for observations throughout the summer.
NEW SPECIES OF THE GENUS BRYCHIUS. (COLEOPTERA).
Authors: Carr F. S.
Published: January 2010

In August, 1925 a couple of days were spent in the vicinity of Pincher Creek, collecting. The prospects were so promising that an attempt has been made each year since to do a little collecting in this and other parts of the Crows Nest Pass. To date the results, especially among the aquatic beetles, have been most gratifying.
RECORDS OF BUMBLEBEES FROM ALBERTA, CANADA. (BREMIDAE: HYM.)
Authors: Frison Theodore H.
Published: January 2010

Few political areas in North America offer so much in the way of interest and instruction to the student of the geographical distribution of bumblebees as the Province of Alberta in western Canada. This is due not only to the fact that extremes in elevation between certain portions of Alberta bring together species of pronounced northern and southern tendencies, a condition duplicated in many parts of western North America, but likewise to the fact that Alberta is a meeting ground of species with decided eastern and western affinities. A somewhat similar state of affairs, though less marked, occurs in the Dakotas as attested by a study of approximately 900 specimens of bumblebees from South Dakota submitted to me for determination by Professor H. C. Severin and recorded by him in the “Sixteenth Annual Report of the State Entomologist of South Dakota,” 1925, pp. 17-20.

Published: January 2010

In rearranging and briefly investigating the species of Lina and some allied genera in our collection, assisted by additional material kindly sent me by Messrs. Carr of Alberta, Hopping of British Columbia, Frost of Massachusetts, and Notman and Shoemaker of New York, the following notes were made, which in some cases correct a few misidentifications or add to the recorded distribution of some species.
TWO NEW SPECIES OF WAGNERIA (TACHINIDAE, DIPT.)
Authors: Curran C. H.
Published: January 2010

The genus Wagneria Desvoidy is represented in America by about a dozen described species, including those named in the present contribution. Two of these I am unable to recognize, the others being included in the key. The two new species differ from the others in the genus by possessing infra-squamal setulae and lacking discals on the intermediate abdominal segments of the males in addition to being larger than the allied species.
TETRAPHLEPS CANADENSIS PROVANCHER, A TRUE TETRAPHLEPS (HEMIP.)
Authors: Drake C. J. , Harris H. M.
Published: January 2010

Through the courtesy of Professor George Maheux, Provincial Entomologist of the Department of Agriculture of the Province of Quebec and Curator of the Quebec Public Museum and Mr. G. S. Walley of the Department of Agriculture of Canada, the writers have recently had the privilege of studying the type specimen of Tetraphleps canadensis Provancher. The specimen is a true Tetraphleps and not a Lycotocoris as was at one time supposed. A comparison with the holotype of T. americana Parshley, kindly loaned for study by Dr. H. M. Parshley of Smith College, shows that this name must stand as a synonym of canadensis. Provancher's description with further notes is given below…..
THE INTRODUCTION AND ESTABLISHMENT OF THE LARCH SAWFLY PARASITE, MESOLEIUS TENTHREDINIS MORLEY, INTO SOUTHERN MANITOBA (HYMEN.)
Authors: Criddle Norman
Published: January 2010

Definite records of injury by the larch sawfly (Lugaeonematus erichsoni Hartig.) in North America only date back to 1881 when Hagen records the insect from Massachusetts. Horv long it had existed on the continent previous to that date is uncertain, but judging from its distribution at the time it was first reported, we may safely conclude that it had been present for a number of years. There is indeed a significant statement by Audubon in which reference is made to the larches being stripped, by a “green caterpillar some three quarters of an inch in length,” which if referable to this sawfly would take our records back to the beginning of the last century.

NOTES ON SOME FLORIDA COLEOPTERA WITH DESCRIPTIONS OF NEW SPECIES
Authors: Blatchley W. S.
Published: January 2010

My last general paper on Florida Coleoptera was prepared in the autumn of 1924, and appeared in the Canadian Entomologist for July, 1925. Since that was written my time has been largely devoted to the final preparation and publication of the “Heteroptera of Eastern North America.” During the three years which have elapsed I have spent the winters at Dunedin on the west coast of Florida, but have made three additional collecting trips, of three or four weeks each, to Royal Palm Park. One of these was in December, the other two in March and April. This park comprises an area of 4,000 acres lying in extreme southern Florida, about 40 miles northeast of Cape Sable.

THE BIOLOGY OF CANADIAN BARKBEETLES
Authors: Swaine J. M.
Published: January 2010

During the course of an investigation carried out some years ago by the writer in the Gaspe peninsula of Quebec, it was discovered that adults of Dendroctonus piceaperda Hopk., Polygraphus rufipennis Kby., Ips perturbatus Eichh., and Ips borealis Sw., cut two sets of tunnels the same season and in some cases hibernated and cut tunnels in the following season. Subsequently, a series of detailed studies on the biology of Canadian barkbeetles has been in progress in field laboratories at Fredericton, N. B., Frater, Ont., Vernon, B.C., and Pender Harbour, B.
