Kanker payudara merupakan kanker yang paling sering dijumpai dan banyak menyebabkan kematian pada perempuan. Keberhasilan kemoterapi hanya sekitar 10-15%. Kendala kemoterapi adalah berkembangnya resistensi terhadap berbagai obat yang disebut multi-drug resistance (MDR). Kunyit (Curcuma longa) adalah tanaman herbal, me…
Poly(ether ether ketone)(PEEK) was synthesized by the aromatic nucleophilic polycondensation reaction of 4,4′-difluorobenzophenone, bisphenol A and 2-methylhydroquinone. Double-arm PEEK macroinitiator containing isopropyl bromide end groups was obtained by bromination with N-bromosuccinimide(NBS), hydroxylation with d…
Part of a leader&s;s role is building morale, and if there are a couple of staff members who are ruining things for everyone else, it is up to us to find a solution. When we establish an expectation for the adults in our school, we should assume they will all do the right thing. Once we establish an expectation that i…
본 연구에서는 분극 전계에 따른 압전 페인트 센서의 특성을 확인하기 위해 충격힘과 분극 전계를 변화시켜 가면서 실험적인 연구를 수행하였다. 페인트 센서 제작을 위해 유연 압전 재료인 Pb(Ni1/3Nb2/3)O3-Pb(Zr, Ti)O2 (PNN-PZT) 파우더와 경화제를 포함하고 있는 에폭시 수지를 중량비 1:1로 혼합 후 몰드를 사용하여 40 × 10 × 1 mm3 크기를 같는 시편을 제작 하였다. 이후 시편의 기공을 제거하기 위해 진공 데시케이터를 사용하였다. 분극 작업을 위해 시편의 전극은 실버페이스트를 윗면과 아랫면에 바르고 하루 동안 건조시켜 제작하였다.…
UvodU novom Zakonu o održivoj uporabi pesticida (NN br.14/2014) definiran je pojam "profesionalni korisnik" -predstavlja osobu koja koristi pesticide namijenjene profesionalnim korisnicima u okviru obavljanja svojih profesionalnih aktivnosti, uključujući primjenitelje, tehničare, poslodavce i samozaposlene, kako u pol…
The effective water management in a polymer electrolyte membrane fuel cell (PEMFC) is one ofthe key strategies for improving cell performance and durability. In this work, an ex situ measurement was carriedout to understand the water droplet behavior on the surface of gas diffusion layer (GDL) as a fundamental studyfo…
Pharmaceutical is a highly regulated industry based on its nature that involves human life. Every decision must be scientifically sound from the early stage in order to provide security and safety to the patient. Only 1 from 4000 synthesized drugs reach the market which cost about $800-900 million dollar within 8-12 y…
This report includes fulfillment of Task 9 of a multi-task contract to further enhance concrete filled fiber reinforced polymer (FRP) tubes, or the Bridge in a Backpack. Task 9 investigates the interaction of water flow under the bridge with the tubes and decking and recommends Manning’s roughness coefficients for wat…

A panel of acid-labile bis-norbornene cross-linkers was synthesized and evaluated for the formation of acid-degradable brush-arm star polymers (BASPs) via the brush-first ring-opening metathesis polymerization (ROMP) method. An acetal-based cross-linker was identified that, when employed in conjunction with a poly(eth…

The article presents a comprehensive low-waste technology is the use of local fuels, which can be used in the technology of some porous building materials. Also provides new methods of preparation of porous building materials based on aggloporite using local fuels and waste energy on the basis of milled peat, fuel bri…
The TOPAZ International Program (TIP) was the final name given to a series of projects to purchase for testing in the United States the TOPAZ-II, a space-based nuclear reactor of a type that had been more fully developed in the Soviet Union than in the United States. The TOPAZ-II represented the more than twenty years…
We perform a statistical analysis of the full set of parity-violating asymmetry data for elastic electron scattering including the most recent high precision measurement from Q-weak. Given the basis of the present analysis, our estimates appear to favor nonzero vector strangeness, specifically, positive (negative) val…
This work analyses properties of relational structures that imply a high degree of symmetry. A structure is called homogeneous if every mapping from any finite substructure can be extended to a mapping over the whole structure. The various types of these mappings determine corresponding types of homogeneity. A promine…

In this research, we investigate electrical performance and electrochemical properties of graphenesupported Pt (Pt/G) and PtM (M = Ni and Y) alloy catalysts (PtM/Gs) that are synthesized by modified polyolmethod. With the PtM/Gs that are adopted for oxygen reduction reaction (ORR) as cathode of proton exchangemembrane…
Some new developments in dithiolene molybdenum model chemistry, in particular focusing on structural aspects of molybdopterin, will be presented. These are, for instance, synthesis, characterisation and reactivity of pyrane dithiolene complexes of molybdenum and tungsten and derivatives thereof. Chemical, electrochemi…
A stress relaxation of the curved reinforced concrete beam problem is studied in this arti- cle. The concrete and armature structural damages are also taken into account.
