Sericulture is an activity where every part can be used for multiple purposes. Sericulture implies significant quantities of secondary and waste products such as perforated silk cocoons, Bombyx mori chrysalides, bedding left-over larval dejections and mulberry plant waste, superseded cocoons, surplus mulberry leaf, root and wood biomass, mulberry fruits, mulberry root biomass etc. Therefore, sericulture to produce only silk fabric can now be transformed into the functional industry by applying appropriate methods in processing the secondary and waste products from sericulture, which can double or even triple the farmers’ income dramatically as obtained from the main activity of silk cocoon production. Thus, in order to ensure a profitable sericulture activity, it is necessary to process these secondary and waste products generated from different sericulture activities to obtain biologically active substances with important uses in: pharmaceutical, cosmetic, paper and cellulose, and organic agricultural food industries. Realizing the scope of utilizing by-products generated from different sericulture activities, in-depth research towards utility optimization is the prime need in placing the sericulture industry on a sound footing. The review is intended to focus on recent advances in comprehensive utilization, diversification and value addition of sericulture resources in broadening the sustainability of sericulture industry.

Authors: Rezaie Maryam , Montazerie Fatomhe
Published: March 2019

Neoseiulus californicus (Acari: Phytoseiidae) is an effective predator in greenhouses which feeds on plant injurious mites. Searching capacity is one of importance in the effectiveness of this predatory mite. In this research, the population fed with corn pollen, walnut and date pollen and the spider mite (four strains) were investigated. The prey-stage preference of N. californicus was studied on different developmental stages of Tetranychus urticae. The predation rate of rearing population of N. californicus was determined; it was used eggs of T. urticae. Experiments were carried out on strawberry disc in Petri dish (6 cm diameter) under laboratory conditions (27±1ºC temperature, 70±5% RH and 16L: 8D photoperiod). After 24 hours, the total numbers of prey consumed were counted. The predatory mites reared on different pollens prefer eggs or nymphs to adults and the Preference Index of different strains was not different. Result of consumed of spider mites by female predatory mites indicated the predation rate of the predatory mites fed with corn pollen (9±1.46), walnut pollen (8.19±0.99) and Date pollen (8.28±0.80) did not any significant difference, however when spider mites and the mentioned pollens were used, the predation rate of predatory mites when fed with T.  urticae (14.74±0.94), Walnut (15.24±1.05) and date pollen (14.17±1.04) show significant difference with the population of corn pollen (10.0±0.95). The predation rate of four strains decreased at present of plant pollens. Use of the predatory mite fed with the different developmental stage of two-spotted spider mite and pollen in the biological control of the pests is useful.
Lab studies on trail following behavior of the termite Hypotermes obscuriceps towards 2-Phenoxyethanol
Authors: Kaur Gurjeet T. , Gajalakshmi Anantharaju S. , Abbasi S. A.
Published: March 2019

Hypotermes obscuriceps is the most abundant of termite species found in North-eastern Puducherry. It has been seen to assimilate ligninous waste kept for degradation in the termireactors designed earlier by the authors by the process of termigradation. Termigradation is a termite-based biodegradation process and involves attracting termites towards the ligninous waste in specially designed reactors. Such reactors are kept in pits or aboveground near termite mounds. In order to increase the number of termites that will move towards the feed kept in such termireactors, 2-Phenoxyethanol (2-PE) was explored in the laboratory for making trails that may attract H. obscuriceps. Five different concentrations of 2-PE, ranging from 0.1 to 0.0005% were explored and in controlled experiments, the numbers of termites that followed the trails made by these levels of 2-PE as a function of time were determined. It was seen that all the trails that contained 2-PE attracted H. obscuriceps and none was toxic to termites for the first 60 minutes.

Authors: Dishan Mariathas A.
Published: March 2019

One of the major constraints to coffee production throughout the world is the damage caused by the Coffee Berry Borer (CBB), Hypothenemus hampei (Ferrari). The first report of the occurrence of CBB appears to be that of 1935 in Rathnapura District in Sri Lanka. It is now prevalent in all areas, at varying degree of damage to both Arabica and Robusta coffee. Damage on coffee berries bribes in heavy losses on economical production of coffee in developing countries, including Sri Lanka. The objective of this study was to identify the infestation level of CBB in six selected coffee cultivars and to assess the CBB populations in coffee fields. Six selected coffee cultivars were, Catimour, S4711, HDT of Arabica species and IMY, CCI, BS5 of Robusta species. The experiment was laid out in randomized complete block design, with six treatments and three blocks. Damage severity was recorded on fifty-four tagged coffee plants. Ten branches were selected from a coffee plant where each branch contained more than fifty berries. Data were collected on the same berry cluster, during three months at weekly intervals. Starting from zero damaged berries, the diameter of coffee berry was measured by using a Vernier calliper (0.1mm). Ninety coffee berries were randomly selected from each of Arabica and Robusta for measurements. The data were recorded continuously during the three months at weekly intervals. The results showed that there were significant CBB damage differences among the coffee cultivars. Among the selected cultivars BS5 was the least damage by CBB and HDT was the most susceptible cultivar and S4711 was also found to be susceptible but to a lesser extent. CBB populations were high in Arabica field than in Robusta field. When the diameter of the coffee berry increase, the level of infestation of CBB also increases.
Status of Fall Armyworm (Spodoptera frugiperda), Biology and Control Measures on Maize Crop in Ethiopia: A Review
Authors: Assefa Fenta
Published: March 2019

Maize (Zea mays) is one of the main and popular cereal crops due to its high value as stable food as well as its stover demand for animal feed and fuel and even for construction purposes. Despite its current productivity is higher than other major cereal crops, the yield productivity is below its potential. These are due to many biotic and abiotic factors that can contribute to its yield potential of productivity to be below the previous productivity. The Fall Army Worm (FAW) is among the major factors contributing to low productivity currently in Ethiopia from its introduction in February 2017. Now it has covered about 52, 962 hectares in 144 districts in six of the major maize-growing regional states, namely Benishangul-Gumuz, Amhara, Tigray, Gambella, Oromia and Southern Nations, Nationalities and Peoples’ Region. FAW, a new devastating insect pest is one of serious major problems for agricultural crop production especially under police family (maize) in Ethiopia under warm and humid conditions. This is due to its ability to breed rapidly, to migrate, and to feed on a wide range of host plants and these make it very difficult to control. Nonetheless, there are several ways of managing the pest reported in other parts of the world that can potentially be adapted and/or validated and used in Ethiopia. Hence, to manage these sporadic pests we have to use different management options. Among those, cultural, chemical, biological and integrated pest management is commonly used in pest infestation. Therefore, this paper initiated with the objective of reviewing the Status of fall armyworm (Spodoptera frugiperda), Biology and control measures on maize in Ethiopia.

An Investigation OfStationarity Properties Of The Turkish Tourism Income Variable
Authors: ERTUĞRUL Hasan Murat , YILDIRIM Selim , AYHAN Fatih
Published: March 2019

Tourism has a
significant impact on economic growth as put forth by the tourism- led growth
hypothesis. Turkey’s earnings from tourism were 31.5 billion dollars in 2015
according to TURKSTAT. This implies that tourism is an important industry for
Turkey and has a significant impact on economy. Therefore, the question whether
a policy implementation in tourism is long-lasting or not is critical for both
the industry and whole economy. This study researches the persistence of
policies in tourism industry, employing tourism income series for period of 2009M1-2015M12
and tests the stationarity of this series using traditional unit root tests as
well as a wavelet-based unit root test developed by Fan and Gencay (2010). Both
seasonally adjusted and unadjusted series have been used. The empirical results
point out that the traditional unit root test has a proclivity to report that
tourism income series is I(1) or non-stationary. On the other hand, the
wavelet-base unit root test indicates that tourism income is stationary. The empirical
result of wavelet-based test implies that impact of a shock on this sector is
transitory. The income in tourism industry will return more or less back to its
meaning the following year.

Examining the Grassroots Participant Legacy of Major Sporting "Supplemental" Events
Authors: Burgess Stephen , Bingley Scott , Urwin Gerry
Published: March 2019

For a considerable time, major sporting events have been investigated to explore their "participation" legacy impact (effect on participation in sports at the grassroots level), often with mixed results. In this article, the authors propose an approach to examine not major events themselves,
but adjacent, supplemental events, and whether such events can contribute to a participation legacy. The authors do this by developing a "grassroots participation ladder," built on the transtheoretical model, which has been amended to examine the stages of behavior between no involvement
in a sport and ongoing sports participation. An initial test of the ladder is conducted via a case study of supplemental events conducted in conjunction with the 2015 ICC Cricket World Cup and involving interviews with event participants to demonstrate how the ladder might be utilized. Results
suggest that previous measurement methods have typically neglected a key constituent, which offers a new recognition of potential participation legacy benefits, and feeds back into suggested methods of planning more effective participation legacy activities in the future.
L’église paléochrétienne de l’établissement fortifié de hauteur de La Couronne à Molles (Allier, Auvergne)
Authors: Martinez Damien
Published: March 2019

L’étude du site de La Couronne à Molles (Allier) s’inscrit dans la mouvance des recherches portant sur l’habitat fortifié de hauteur durant le haut Moyen Âge initiées au début des années 2000. Les fouilles programmées engagées en 2010 ont mis au jour les vestiges particulièrement bien conservés d’une forteresse construite à la fin du ive ou au début du ve siècle, dans la périphérie nord-est de l’ancienne cité de Clermont. Le point de départ de ces travaux a été l’étude d’une vaste église édifiée au plus tôt autour des années 450 et concernée par d’importantes transformations au cours du vie siècle. Celle-ci a incontestablement fait de la forteresse un pôle religieux important au cours de la période mérovingienne et a joué un rôle de premier plan dans l’organisation et l’évolution du site tout au long du haut Moyen Âge. Le présent article propose un premier bilan des résultats des recherches conduites sur cet édifice et son environnement.

Published: March 2019

Le site du « Clos de l’Abbaye » à Cysoing est un établissement religieux dédié à saint Calixte et fondé vers 850 par Gisèle et Évrard de Frioul. La parcelle fouillée, d’environ 5 000 m², semble correspondre aux communs de l’établissement du haut Moyen Âge. Le site se caractérise par un fossé délimitant une installation composée de plus de 150 creusements ou niveaux. L’étude des données environnementales témoigne des pratiques culturales ainsi que de la gestion du bétail. Zones d’ensilage, four, fosses, trous de poteau, cabanes excavées illustrent une forte activité. La transformation de produits primaires (céréale, laine, os, métaux) en produits finis ou semi-finis (production alimentaire, textile, vêtements, bijoux) peut être appréhendée par l’intermédiaire de divers faits archéologiques ou d’artefacts. Le mobilier céramique, peu abondant, contribue à dater le site et permet d’entrevoir certains réseaux d’approvisionnement.

Authors: Berounský Daniel
Published: March 2019

Cet article étudie des représentations textuelles précédemment négligées d'une tradition rituelle assez inhabituelle consistant à brûler un renard. Des textes mongols similaires ont déjà été discutés par un certain nombre de chercheurs et cet article souligne le fait que ces textes mongols sont, de manière évidente, des traductions d’originaux tibétains. Cet article traite d’un corpus de textes récemment publiés provenant de Dongtrom (lDong khrom) ou Datshang (mDa’ tshang) en Amdo, parmi lesquels se trouvent cinq versions tibétaines apparentées à des versions mongoles. Trois autres textes tibétains sont également discutés. La mention fréquente des êtres nyen (gnyan) et du prêtre mythique Nyen Bon Thangthang Drolba (gNyan bon Thang thang sgrol ba) désigne néanmoins la Collection nyen (gNyan 'bum) comme la source textuelle principale fournissant le contexte de la tradition.

Authors: Rajasekar B. Ruban , Asokan R. , Ramesh C. , Selvakumar V. Jamin Daniel , Dinesh M.
Published: March 2019

The objective of the research is to investigate the fatigue life of intra-ply hybrid Carbon-Aramid laminate with Epoxy resin in on-axis and off-axis directions. Three different off-axis angles of 15, 30 and 45 degrees were considered for the present work. The intra-ply hybridization is used to combine the superior mechanical properties of Carbon fibre with excellent elongation-to-failure property of Aramid fibre in the same lamina. The fatigue test was performed using load control using a frequency of 5Hz. The fatigue behaviour was studied for Carbon/Epoxy, Aramid/Epoxy, Carbon-Aramid/Epoxy, Carbon-Aramid/Epoxy - 15, Carbon-Aramid/Epoxy - 30 and Carbon-Aramid/Epoxy - 45 with the stress ratio of R = 0.1. The ultimate tensile strength decreases progressively for Carbon/Epoxy, Carbon-Aramid/Epoxy, Aramid/Epoxy, Carbon-Aramid/Epoxy - 15, Carbon-Aramid/Epoxy - 30 and Carbon-Aramid/Epoxy - 45. The effect of off-axis loading indicates that the increase of fibre angle influences the decrease in tensile strength and fatigue life.

Published: March 2019

In recent times most of the automotive vehicle accidents are increased day by day in India. Recent causes of the accident shows that more than 20% of accidents are caused due to health issues which occur to drivers while driving the vehicle. In the proposed project we had been monitoring the status of health condition of the driver by using sensors such as pulse rate sensor and temperature sensor. The heart beat rate falls below the lower limit and above the higher limit to the driver. The driver can be prevented from driving the vehicle when he is in extreme emotion such as heart attack, arrhythmias, heart stiffening or weakening, cardiomyopathy, stress, anxiety, depression etc. The speed of the vehicle is measured by speed sensor in the vehicle. The ultrasonic sensor which is used to sense the object placed in the front of the vehicle. The result is to create a system capable of contributing to the reduction of collisions. The driver who suddenly suffers from health issue especially heart attack while driving the vehicle cannot handle the vehicle because during heartache the movement of hands is difficult to control the vehicle which leads to accidents. The heart rate sensor placed in seatbelt of the driver and heat sensor in the driver seat. The sensors collect the data and send it to the control unit which interprets the data with the standard value and if some values are unusual may be in heart rate, blood pressure. The control unit sends out a warning signal to the driver and if the driver doesnâ€™t show any reaction within the set time the braking system is actuated.

Published: March 2019

Vibrations are caused in an engine due to the continuous motion of reciprocating and rotating parts. Engine mounts are used as the vibration isolators from the engine to frame. The absorbing capacity of the mounts should be large enough to withstand the vibrational force for longer periods. Engine mountâ€™s strength depends upon the material and the type of the design. The modelling and assembly of the engine mount is done using solidworks and the analysis of the mount is done using Ansys software. Modal analysis is done on the engine mount at working frequency. With the results obtained, factor of safety is calculated and it is compared with the existing mount. The proposed engine mount model results in encouraging factor of safety value.

Published: March 2019

Scarcity and inflated cost of petroleum reserves along with environmental pollution concerns urged the researchers to identify a better alternative source of eco-friendly bio-energy. In this study, oxygenated biodiesel derived from Jojoba oil was used in a compression ignition engine to analyse the engine characteristics in the presence of multi-walled carbon Nanotubes (MWCNT) at 50 ppm, 100 ppm and 150 ppm concentrations. Taguchiâ€™s approach based experimentation identified the stability of modified fuel blends ratios of n-butanol, biodiesel and MWCNT. The Jojoba biodiesel was characterized using FTIR and GC MS techniques to understand the presence of fatty acid methyl esters in the biodiesel. Higher brake thermal efficiency and significant reduction in specific fuel consumption were observed in fuel blend with MWCNT. D70JJBD20O10CNT100 showed higher in-cylinder pressure and heat release rate due to micro-explosion of carbon nanotubes at full load condition. The ignition delay was also significantly affected with the addition of MWCNT. The exhaust emission like un-burned hydrocarbon, oxides of carbon, oxides of nitrogen and smoke exhibited noticeable variations with the modified fuel blends.

Biodiesel synthesis from the pongamia oil seed and its characterization is elaborated in this paper. A double stage transesterification i.e. acid catalysed transesterification and base catalysed esterification are adopted to reduce the free fatty acids content and conversion of triglycerides into methyl esters. In this process, H2SO4, NaOH and methanol are used at the methanol/oil molar ratio of 7:1. By this process, 95% of pongamia biodiesel is obtained. The physiochemical properties like calorific value, Cetane number, density, kinematic viscosity, flash point, fire point etc. are analysed and it is found to be within the ASTM standards. GC-MS analysis indicated the existence of 14 prominent fatty acids with oleic acid as the major constituent. 13C and 1H NMR results supported the GC-MS data and it also confirmed the conversion efficiency of converting the vegetable oil into PBD as 87.23%. The shifting and appearance of major peaks in the FT-IR spectrum confirmed the formation of FAMEs from the triglycerides.

Authors: Lilly Mercy J. , Prakash S.
Published: March 2019

Self-healing polymeric composites are a class of functional composites which heal itself during damage. Out of the many methods of self-healing, micro-capsule based self-healing process is the proven and established method where the healing agent stored in the capsule breaks and seals up the gap after the polymerization reaction with the suitable catalyst. The incorporation of the capsule in a polymer matrix in a random fashion makes it challenging to model the composite material. This paper explains the modelling and simulation of the self-healing composite using MIDAS NFX FEA software. The effect of self-healing composition - micro-capsule size and concentration on the static mechanical properties of the composite is explored. The capsules are integrated in the polymer matrix as a representative volume element using the rule of mixtures. The classical laminate theory was used to identify the critical ply failure.

Politics and politicking in Nigeria has assumed a considerably new dimension. Actors articulate their ideology and programmes, and construct their subjects and experiences in diverse linguistic processes with a view to achieving political victory. This paper examines clause structures of President Buhari’s My Covenant with Nigerians to reveal the transitivity processes employed by the President in this famous campaign speech in 2015 presidential election. This study utilized Transitivity Processes, which is rooted in Halliday’s (1985) Systemic Functional Grammar, in order to uncover different process types and main participants in the speech, and to explain the functions which these processes perform in the speech in helping the speaker to convey his ideology to Nigerians and convince them to rally support for him. Specifically, objective of this study is the uncover transitivity process types in the speech, their frequency, function and ideological underpinnings. The study reveals that President Muhammadu Buhari utilized mental and verbal processes perception, affection, cognition and volition, and verbal process of saying to appeal to the masses, and to commit himself to serve Nigerians. He equally used material and relational processes to encode his ideology, persuade the people and achieve political victory.

The objective of the present study was to investigate the effect of task based language learning on developing speaking skills of secondary level learners. To achieve this objective, a task based instructional programme consisted of four units of textbook of grade IX was developed. The students of IX grade of Islamabad district were the population of the study. Two groups experimental and control were randomly taken in a natural setting from a randomly selected school of Islamabad district. Both groups were pre and post-tested to determine the difference in their mean scores. Both groups were administered a teacher made speaking skill test as pre-test before starting intervention of treatment. The experimental group got treatment, while control group was taught conventionally for 45 days. Same teacher made speaking skill test was administered to both experimental and control groups as post-test after 45 days. Two tailed t-test was applied at 0.05 levels. The results of the present study showed statistically significant differences between mean scores of the experimental group subjects in term of speaking skills as the post-test scores of experimental group were noticeably higher than the scores of control group. The results of the study support the effectiveness of TBLL as a foreign language. The present study recommends that Pakistani teachers should adopt TBLL approach which is pragmatic, instead of struggling with obsolete traditional methods in second language acquisition.
