Effect of Light and Feed Restriction During Rearing on Production Performance of Egg Strain Layers
Ahsan-ul-haq, Ahsan-ul-haq,Ahmad, Nazir,Rasool, Shahid,Shah, T.H. Asian Australasian Association of Animal Productio 1997 Animal Bioscience Vol.10 No.6
432 Babcock ISA white leghorn pullets reared for 8 weeks on a standard managemental conditions were exposed to feed/nutrient and light restrictions from 9 to 20 weeks of age. Four feeding regimes i. e. 100, 85 or 70 percent of the recommended allowance and low energy (2,500 Kcal/kg) low protein (13% CP) ration were fed each in the three light regimes i. e. (A) Natural day light starting from 13.24 hr/day at 8 weeks of age and ending 10.41 hr/day at the end of 20 weeks; (B) Constant 11 hr/day light and (C) starting with 13 hr/day at 8 weeks and decreasing @ 20 min/week till 20 weeks of age. At the age of 20 weeks all the birds were shifted to separate cages under uniform lighting feeding and management. During the 21st week light was increased to 12 hr a day and thereafter with an increase of 30 min per week, increased to 16 hr a day at the age of 29 weeks. From 20 weeks onward till 72 week age, all the birds were offered commercial layer rations ad libitum, prepared according to climatic conditions. The results of the study revealed that birds reared under natural and constant light had higher weights than decreasing light, yet they could not out perform during production period. The effect of feed and nutrient restriction, on the other hand, was found significant during rearing as well as production period. The birds exposed to higher level of feed and those exposed to nutrient restriction were lighter in weight. The 100% fed birds laid their first egg at an early age. However, those reared on 85% of the recommendation excelled all other groups in terms of produced number of eggs, egg mass, hen housed and hen day production and net returns.
Solar feed water heating feasibility for a conventional steam power plant
Ahsan Alam,Mubashir Ali Siddiqui,Naveed ur Rehman 대한기계학회 2017 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.31 No.7
Technical and economic feasibility of heating feed water through parabolic trough solar collectors has been discussed in this paper. This integration of solar energy with steam plants saves extraction steam, thus increasing turbine output. The study is based on a 210 MW Heavy fuel oil (HFO) fired power plant for Karachi weather conditions. Pressurized hot water storage system is used as heat storage medium. TRNSYS software is used to find out useful energy collected through parabolic trough collectors and heat storage in pressurized hot water storage system. Life cycle savings (LCS) using HFO prices of two different periods i.e. May, 2014 (higher HFO price) and Feb., 2016 (lower HFO price) are calculated and compared. Effect of change in HFO price on LCS is also presented. Integration of higher pressure FWH with solar energy is found more feasible in terms of LCS as compared to lower pressure FWH. Same methodology can be deployed on other plants around the globe to determine LCS and economic feasibility.

The crystal structures of anhydrous and solvated forms of 7-hydroxy-4 methyl coumarin have been analyzed on the basis of energies responsible for holding the moiety in a 3D pattern through weak intermolecular interactions. The lattice energy as well as intermolecular interaction energies of the stabilizing molecular pairs extracted from crystal packing for both structures have been evaluated using PIXEL method. The energies are further split into coulombic, dispersion, repulsion and polarization components, which facilitates in analyzing the stabilizing roles of weak interactions. Lattice energy calculations show that anhydrous form is more stable than hydrous form. Moreover, Hirshfeld surfaces and fingerprint plots were generated using Crystal Explorer 3.0. Critical analysis of Hirshfeld surfaces and fingerprint plots provides essential inputs about the differences in crystal packing of structures and associated intermolecular interactions.
The Impact of Loyalty Program on Customer Retention: Empirical Evidence from Bangladesh
AHSAN, Syed Md. Hasib,ALAUDDIN, Md.,ALAM, Mohammad Manjur,NAZIA, Adiba,ISLAM, Tasnim Korea Distribution Science Association 2022 The Journal of Asian Finance, Economics and Busine Vol.9 No.6
The purpose of this paper is to examine how loyalty programs designed by retail stores affect customer retention. The present study is one of the few empirical studies finding the role of different loyalty programs that help to build customer retention. The study also seeks to explore the moderation role of customer perceived value between intrinsic motivation - customer retention and extrinsic motivation - customer retention. The researchers employed a quantitative research design to collect data from the 350 respondents who purchased goods from the retail chain/departmental stores in Bangladesh. The collected data are then analyzed using structural equation modeling. The result of their findings indicated that the size of the organizational reward has a positive effect on intrinsic and extrinsic motivation; further extrinsic motivation has a significant relation to customer retention. Surprisingly, no support was found for the positive impact of intrinsic motivation on customer retention. Customer perceived value (CPV) is critical as a moderator in building client retention, which improves the positive association between extrinsic motivation and customer retention. CPV, on the other hand, was found to mitigate the negative link between intrinsic motivation and client retention.

The Electrostatic Inkjet system has a huge number of applications in cost and time effected manufacturing of printed electronics like RFID, flexible display, solar cell, sensors, batteries etc. So, the fundamental focus will be to investigate the drop generation phenomena by applying the electrostatic forces. Electrostatic inkjet printing for printed electronics technology is advancing rapidly but it s still in its infancy as inkjet printing system is not able to design complicated devices. This paper explains the behavior of the multiphysics phenomena of the Drop on Demand (DOD) electrostatic Inkjet system for printed electronics devices.
Evaluation of Anti-venom effect of Tiryaq-e-arba in rabbit models
Ahsan, Mohd. Tarique,Rani, Seema Cellmed Orthocellular Medicine and Pharmaceutical 2020 셀메드 (CellMed) Vol.10 No.4
Background: Tiryaq-e-arba is a polyherbal Unani antidote/antivenom formulation used in the management of poisoning due to snake bite, scorpion bite as well as in cold poisons since time immemorial. Objectives: Tiryaq-e-arba was not evaluated scientifically before this study carried out, therefore it was studied for antivenom activity by testing on plasma fibrinogen level in Russell's Viper envenomation in rabbits. Material &Methods: The anti-venom activity of the test drug was studied by observing its effect on plasma fibrinogen level in Russell's Viper envenomation in rabbits by the method of Netelson. Results: The plasma fibrinogen level was found to be 171±665.04 mg/100 ml of blood, 36.18±1.12 mg/100 ml of blood, 33.14±0.52 mg/100 ml of blood and 17.9±1.65 mg/100 ml of blood at 0, 1, 3 and 6 hours respectively in control animals while in the test animal it was found to be 157.13±3.44 mg/100 ml of blood, 41.13±2.69 mg/100 ml of blood, 62.09±1.65 mg/100 ml of blood and 54.39±0.73 mg/100 ml of blood respectively. The test showed that though the plasma fibrinogen level in the test lower at 0 hour but it was greater in the control animals at 1, 3 and 6 hours. The increase in plasma fibrinogen level in the test animals at 3 and 6 hours was statistically significant (P<0.001). Conclusions: The finding of the present study was that Tiryaq-e-arba possesses antivenom activity which scientifically support the Unani claim that it is Dafe-Sumoom-al-Hevan (Antivenom or Antidote) and the use of this preparation in corresponding diseases.

This paper analyzes the financial policies pursued in the major industrial countries under the flexible exchange rate regime, and links misalignments in policies and their mixes to exchange rate variations among the major currencies. A number of indicators note that misalignments in fiscal policy led to a corresponding divergence of fiscal and monetary policy mix among the industrial countries. and, together. contributed to the rapid appreciation of the dollar during the early 1980s. The continued liberalization of international capital movements and the differences in the savings rate also amplified the effects of policy divergences and their mixes on the exchange rate movements.
