Cancer is considered one of the deadly diseases in the world. According to WHO cancer now causes more deaths than all coronary heart disease. The incidence and mortality of the worldwide major cancers are now available in the GLOBOCAN series of the International Agency for Research on Cancer. The transition of global demographic and epidemiologic shows that burden of cancer will increase particularly in low and middle income countries, with over 20 million new cancer cases expected annually as early as 2025. Medicinal plants made known to be prospective and useful job for the treatment of several diseases and disorders from prehistoric days to nowadays. One of the commonly used plants, which have supporting evidences from the recent scientific data for the different types of cancers, is Carica papaya. Papaya (Carica papaya) is widely used as folk caloric herbal medicine, being a powerhouse of nutrients and accessible throughout the year. It is a rich source of three powerful antioxidants, the minerals, vitamins and contains high content of fibre. Carica papaya has provided many remedies for various diseases from ancient days to nowadays, and is regarded as a Nutraceutical. Because of this comprehensive medicinal value of Carica papaya, we are trying here to convey the reports studied especially for the anticancer activities of the age-old fruit, which will help researchers to pull in concert data and may be a "lead" for the one of the dangerous disease in the world.

Polypyrrole (ppy) has been synthesized by employing [Co(NH3)6]Cl3 as a new oxidizing agent under basic condition in aquous solution. The optimized ratio of monomer to oxidizing agent has been taken as 1:2. The reaction was allowed to continue for 24-48 h at room temperature. The as synthesized ppy displayed well defined morphology, which was seemed as time dependent. It was nanospheres at 24 h, micro/nano mixture at 36 h and microspheres and microfibers at 48 h. The FTIR confirmed the formation of ppy due to the presence of characteristics broader ring and N-H stretching vibrations. The XRD showed the development of crystallites only within the fibrous ppy. The thermal and structural correlation was determined using TGA and DSC techniques alongwith SEM. The polymer was found to be considerably more stable as compared with similarly synthesized using other such oxidants. The conductivity of pure polymer and effect of NH3 over its conductivity was analyzed by four probe technique. Its strong potential of NH3 sensing has been confirmed from this technique due to showing linear increase in its conductivity. These results demonstrated that cobalt(III) is a potential oxidizing agent to produce thermally stable nano/microspheres of ppy. Moreover, the material was found quite useful for its characteristics of NH3 sensing that can be applied for other nitrogenous bases.

Ag@polycarbazole coaxial nanocables (CNCs) have been successfully fabricated by the oxidative polymerization of carbazole over Ag nanowires (NWs) in acetonitrile. The morphology of Ag NWs and CNCs was studied by employing a transmission electron microscope (TEM) and a scanning electron microscope (SEM), which showed them to be a monodisperse material. The thickness of the polymer sheath was found to be 5 nm to 8 nm by observation under a high-resolution transmission electron microscope (HR-TEM). Energy dispersive X-ray spectroscopy (EDS), FT-IR and Raman measurements were used to characterize the polymer sheath, which demonstrated it to be a carbon material in polycarbazole form. X-ray photoelectron spectroscopy (XPS) was used for an interfacial study, which revealed that Ag surface atoms remained intact during polymer growth. In the end, zeta potential showed that the dispersion stability of Ag NWs increased due to polymer encapsulation, which is significant to obtain a particular alignment for anisotropic measurement of electrical conductivity.

In this paper we propose generalized multi-phase multivariate ratio estimators in the presence of multiauxiliary variables for estimating population mean vector of variables of interest. Some special cases have been deduced from the suggested estimator in the form of remarks. The expressions for mean square errors of proposed estimators have also been derived. The suggested estimators are theoretically compared and an empirical study has also been conducted.

<P>This paper presents the flight path planning algorithm in a 3-dimensional environment with fixed obstacles for small unmanned aerial vehicles (SUAVs). The emergence of SUAVs for commercial uses with low-altitude flight necessitates efficient flight path planning concerning economical energy consumption. We propose the visibility roadmap based on the visibility graph approach to deal with this uprising problem. The objective is to approximate the collision-free and energy-efficient flight path of SUAVs for flight missions in a considerable time complexity. Stepwise, we describe the construction of the proposed pathfinding algorithm in a convex static obstacle environment. The theoretical analysis and simulation results prove the effectiveness of our method.</P>
An adroit unrelated question randomized response model with sundry strategies

When sensitive topics such as gambling habits, drug addiction, alcoholism, tax evasion tendencies, induced abortions, drunk driving, past criminal involvement, and homosexuality are the focus of open or direct surveys, it becomes challenging to obtain accurate information due to non-response bias and response bias. People often hesitate to provide truthful answers. Warner introduced an ingenious method to address this issue. In this study, a new and unrelated randomized response model is proposed to eliminate misleading responses and nonresponses caused by the stigma associated with the attribute being investigated. The proposed randomized response model allows for the estimation of the population percentage with the sensitive characteristic in an unbiased manner. The characteristics and recommendations of the proposed randomized response model are examined, and numerical examples are provided to support the findings of this study.

Single crystals of a lanthanide metal organic complex neodymium tartrate trihydrate have been synthesized. Scanning electron microscope reveals the morphology of single crystals as dipyramidal. X-ray crystal structure analyses reveal that the complex has tetragonal structure. The effect of ligand on the magnetic moment of Nd ion was studied. The elemental analyses, infrared spectra and thermogravimetric behaviour of the complex were also studied. The activation energies corresponding to different stages of decomposition were also calculated.
Herbal pathies (Unani, Ayurveda) need to review their way of research

World health organization has recently published a strategic plan for the development and promotion of traditional system of medicine. Herbal pathies especially Unani and Ayurvedic systems of medicines have great scope in this aspect. But, there are several problems with these pathies in the current era, as the way of research and identification is still on classical system. The correct identification of medicinal plant is one of the major problems in both the system. This should be corrected with the modern tools and techniques. The various types of data including recent discoveries, economical growth, ethnobotanical literature and extremely rapid increase in herbal journals and books have emerged great scope for these pathies. At the same time several challenges and threats are present including herb-drug interaction, false reports, toxicity studies etc. In this review paper, opportunities, threats, and researches to be focused will be discussed.
