Sundarijal River supply drinking water in Kathmandu city, Nepal and to study the nitrate concentration, 10 different sample from locations of was taken. The method for removal presence tested using hydroxylamine hydrochloride dose at 25±2 0C with 35 minutes contact time. Samples reduction increase increasing dosages, up certain limit. That mean 0.5g, 0.6g 0.8g dosages hydrochloride, not observe...

Let m, k be natural numbers. One can check that RHK(m,k) is real. Let m, k be natural numbers. Then RHK(m,k) is a real number. In this article we present several logical schemes. The scheme ExComplex CASE deals with a binary functor F yielding an element of C, and states that: For every k there exists s1 such that for every n holds if n ≤ k, then s1(n) = F (k,n) and if n > k, then s1(n) = 0C fo...

Ilemodynamic and echocardiographic measurements were obtained in 15 patients prior to cardioversion and immediately, one, three, and five hours after ca ,dioversion of atrial fibrillation to normal sinus rhythm1z4. j ve hours after cardioversion, there was improvement in cardiac index (P < 0.005), in stroke index (P <0.005)1and i11 stroke work index (P < 04)25), but no significant change in hea...

Geopressured reservoirs can serve as ample source of geothermal energy with temperatures as high as 140 0C. Salinities are typically high in these reservoirs due to the dissolution of surrounding salt domes. Cement retrogression can occur under these geopressured geothermal conditions resulting from calcium silicate hydrate [3CaO2SiO23H2O] phase in hydrated cement converting to alpha dicalciu...

In this study, sedimentary organic matter of oil shale rejects, calschist, shale fine and the so called retorted shale from Irati formation was characterized. EPR was used to analyse the samples regarding loss of signal in g = 2.003 associated to the organic free radical with the calcined samples and washing with hydrogen peroxide. The radical signal was detected in all samples, however, for th...

Синтезовано наночастинки (30—50 нм) кальцію фосфатів апатитового типу в умовах співосадження з водних розчинів при мольних співвідношеннях Са/Р = 1,67, CО32–/РО43–= 1 та (Cu2+, Zn2+) : Ca 50 і температурі 25 0C. Згідно даними хімічного аналізу, синтезовані фосфати містять катіонні аніонні допанти: Na+ (0,19—0,21 % мас.), Cu2+ (0,42 мас.) Zn2+ (0,36 C (0,98—1,02 мас.). В ІЧ-спектрах модифіковани...

The coastal waters utilization that has potential to be developed in Barru regency is the cultivation of pearl oysters (Pinctada maxima). However, get maximum results, site selection through inventory activities and mapping an important early stage do. purpose this study was assess suitability for maxima) farming. method used current were characteristics analysis, plankton abundance SID analysi...

Gula aren diperoleh dari nira hasil sadapan pohon dan merupakan salah satu bahan baku pembuatan makanan maupun minuman. Pembuatan gula yang ada di Desa Tanggari Minahasa Utara Sulawesi menggunakan bakuair (saguer), akan tetapi pada proses masih tradisional dengan sepenuhnya tenaga manusia. Penelitian ini bertujuan untuk membuat prototype alat pengolah kontrol Programable Logic Controler (PLC) m...

The effects of African wild lettuce leaf meal (Lactuca taraxacifolia) were investigated on the sperm and egg quality C. gariepinus, (mean body weight, 190.29g). Five diets with crude protein 35% formulated different inclusion levels powder. T1 (control) has 0 g WLM, while T2, T3, T4 T5 0.02, 0.03, 0.04 0.05g/100g diets. A total 70 juveniles gariepinus randomly distributed twice into 120 liter t...
