Conservation of Forestry Biomass with the Use of Alternative Resource  [PDF]
Manju Agarwal, Rachana Pathak
Open Journal of Ecology (OJE) , 2015, DOI: 10.4236/oje.2015.54009
Abstract: The effect of the alternative resource and time delay on conservation of forestry biomass is studied by considering a nonlinear mathematical model. In this paper, interaction between forestry biomass, industrialization pressure, toxicant pressure and technological effort is proposed and analysed. We find out the critical value of delay and observe that there is Hopf bifurcation. Using the normal form theory and the center manifold theorem, we determine the stability and direction of the bifurcating periodic solutions. Numerical simulations are given to illustrate the analytical results.
Experimental Proof of Mass in Photon  [PDF]
Narendra Swarup Agarwal
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.65068
Abstract: The present work deals with the mass of photon which creates a force at the contact point of reflection resulting in slight deviation of photon from its path after reflection. Only the mass of photon can cause deviation due to inertial force. If photon has no mass, it cannot deviate. It is also found that this deviation of photon depends on the angle of polarization plane of laser light with respect to reflecting mirror. Such variation in the angle of deviation by the plane of polarization proves that the mass of photon is neither in the centre of photon nor distributed uniformly but located off-centre (away from the centre of photon). This work proves that photon has mass and the most important part of this work is to discover that the mass of the photon is located off-centre (away from the centre of photon). This discovery explains Wave Particle Duality of electromagnetic radiations.
Discovery & Proofs of a Nucleus of Mass and Charge in the Photons/Quantum Particles  [PDF]
Narendra Swarup Agarwal
Journal of Modern Physics (JMP) , 2018, DOI: 10.4236/jmp.2018.912137
Abstract: This work discovers and proves that all the photons/quantum particles have a “Nucleus of mass and charge.” The nucleus is located off-center in the particles. The constructive, destructive and intermediate Interference phenomena decisively discover and prove the presence of only one nucleus of the mass located off-center in a photon, like an atomic nucleus. The mass in the nucleus of a photon develops varying forces to move the photon as a wave. The Wave-Particle Duality is the most significant proof of such a nucleus of mass. The formation of an electromagnetic wave by a photon proves the presence of a charge in the nucleus of the photon. The Quantum Theory, developed about 100 years back, simplified the understanding of matter and energy at the atomic/subatomic levels. However, the Quantum Theory remains incomplete and cannot explain even a single quantum phenomenon. The New Quantum Theory, developed in the year 2012, is based on the similarity of an atomic nucleus as well as the solar system with the Sun as its nucleus of the mass and the charge. The New Quantum Theory explains all the Quantum Phenomena and matches with the Classical Mechanics as well as the Theory of Electromagnetism. The experiments described in this work, using high precision instruments, determine the mass, the charge and the diameter of a photon/quantum particle.
Emergencies in Dental Operatory
Pankaj Agarwal,Ashu Agarwal
Indian Journal of Dental Advancements , 2010,
Abstract: ED visits for dental care are on the rise. Some dental conditions can progress to life-threatening complications; stabilizing patients in such cases is incumbent on the emergency physician, as is management of pain and, to some extent, of the dental condition or injury itself. This article reviews basic dental anatomy as well as nontraumatic and traumatic causes of dental pain.
PULP dead or alive
Pankaj Agarwal,Ashu Agarwal
Indian Journal of Dental Advancements , 2011, DOI: 10.5866/3.4.687
Abstract: A pain response to hot, cold or an electric pulp tester indicates the vitality of only a tooth's pulpal sensory supply; the response does not give any idea about the state of the pulp. Although the sensitivity of these tests is high, when false-positive and falsenegative results occur, they may affect the treatment of the tooth. A tooth falsely diagnosed as nonvital with an electric pulp tester may undergo an unnecessary root canal, whereas one falsely diagnosed as vital may be left untreated, causing the necrotic tissue to destroy the supporting tissues (resorption). The vascular supply is more important to the determination of the health of the pulp than the sensory supply. Pulp death is caused by cessation of blood flow and may result in a necrotic pulp, even though the pulpal sensory supply may still be viable. The pulp can be healed only if the circulating blood flow is healthy. Although still under investigation, diagnostic devices that examine pulpal blood flow, such as the pulse oximeter and laser Doppler flowmetry, show promising results for the assessment of pulp vitality.

A study of dysmenorrhea during menstruation in adolescent girls
Agarwal Anil,Agarwal Anju
Indian Journal of Community Medicine , 2010,
Abstract: Research question: What is the prevalence of dysmenorrhea severity and its associated symptoms among adolescent girls? Objectives: (1) To study the prevalence of dysmenorrhea in high school adolescent girls of Gwalior. (2) To study the evidence of severity of the problem with associated symptoms and general health status. Study design: An explorative survey technique with a correlational approach. Setting and Participants: Nine hundred and seventy adolescent girls of age 15 to 20 years, studying in the higher secondary schools (Pre-University Colleges) of Gwalior. Statistical analysis: Percentages, Chi-square test, and Test-Retest Method. Results: The prevalence of dysmenorrhea in adolescent girls was found to be 79.67%. Most of them, 37.96%, suffered regularly from dysmenorrhea severity. The three most common symptoms present on both days, that is,day before and first day of menstruation were lethargy and tiredness (first), depression (second) and inability to concentrate in work (third), whereas the ranking of these symptoms on the day after the stoppage of menstruation showed depression as the first common symptoms. Negative correlation had found between dysmenorrhea and the General Health Status as measured by the Body surface area.
The Endplate Morphology Changes with Change in Biomechanical Environment Following Discectomy  [PDF]
Aakash Agarwal, Anand K. Agarwal, Vijay K. Goel
International Journal of Clinical Medicine (IJCM) , 2013, DOI: 10.4236/ijcm.2013.47A1002
Abstract: Bone is a dynamic structure and is known to respond to changes in the load over time, in accordance with Wolff’s law. It states that the bone changes its shape and internal architecture in response to stresses acting on it [1]. Therefore, any structural changes in the spine may lead to bone remodeling due to changes in the optimal stress pattern. The changes in apparent density and thickness of the endplates following discectomy of varying amounts were analyzed. The study design coupled a bone remodeling algorithm based on strain energy density theory of adaptive remodeling with an experimentally validated 3D ligamentous finite element model of the spine. The apparent density and thickness of the index level endplates decreased above and below the region of discectomy. On the other hand, these parameters showed increases at the remaining regions of the endplate. There were no correlations between the amount of nucleus removed and the average percentage changes in apparent density and thickness of endplate above and below the discectomy region. However, the average percentage changes in apparent density and thickness at endplate in the other region increased with increase in amount of nucleus removed. These predictions are in agreement with the clinical observations [2-6].
Mathematical Modeling and Analysis of Tumor Therapy with Oncolytic Virus  [PDF]
Manju Agarwal, Archana S. Bhadauria
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.21015
Abstract: In this paper, we have proposed and analyzed a nonlinear mathematical model for the study of interaction between tumor cells and oncolytic viruses. The model is analyzed using stability theory of differential equa- tions. Positive equilibrium points of the system are investigated and their stability analysis is carried out. Moreover, the numerical simulation of the proposed model is also performed by using fourth order Runge- Kutta method which supports the theoretical findings. It is found that both infected and uninfected tumor cells and hence tumor load can be eliminated with time, and complete recovery is possible because of virus therapy, if certain conditions are satisfied. It is further found that the system appears to exhibit periodic limit cycles and chaotic attractors for some ranges of the system parameters.
Lattice Paths and Rogers Identities  [PDF]
Ashok Kumar Agarwal, Megha Goyal
Open Journal of Discrete Mathematics (OJDM) , 2011, DOI: 10.4236/ojdm.2011.12011
Abstract: Recently we interpreted five q-series identities of Rogers combinatorially by using partitions with “n +t cop-ies of n” of Agarwal and Andrews (J. Combin. Theory Ser.A, 45(1987), No.1, 40-49). In this paper we use lattice paths of Agarwal and Bressoud (Pacific J. Math. 136(2) (1989), 209-228) to provide new combinatorial interpretations of the same identities. This results in five new 3-way combinatorial identities.
