Abstract: Nowadays, data and information gathering became the core of almost all technologies. The collection of this data, its arrangement and orientation in a way that provides easy access, manipulation, updating and management is what’s called “Database”. While knowledgebase is like a reservoir, it commonly stores the obtained answers to proposed questions, or saves the solutions to previously faced problems, thus providing speedy search, recovery and reuse. The approach of transferring database to knowledgebase will greatly help in benefiting from the advanced features of Knowledgebase, and this can be achieved by creating a practical algorithm which is presented in this paper to improve data representation and to be able to predicate extra facts depending on rules. The proposed approach achieves moving traditional database into logic syntax. A case study is presented to reflect implementation of the algorithm. This paper is towards the database community to improve the overlap with the expert systems and integrate between them, and the proposed transferring algorithm will be of great support to all researchers in the field of Database and Knowledgebase.

Abstract: This study was conducted to evaluate the effects of different planting density (100×100 cm, 60×60 cm, 30×30 cm) on yield and yield components of three varieties (Buan-1, Changwon-1 and Yunnam-1) varieties of castor beans (Ricinus communis L.). It was observed that number of branch per plant, number of seed per plant and weight of seeds per plant were decreased with the increasing planting density, but 100-seed weight was not significantly different in all three varieties of castor beans. As plant density increased, yield of castor beans increased as the number of branch per unit area and 100-seed weight. In Buan-1, number of seed per unit area was increased with the increase in planting density. However, Changwon-1 and Yunnam-1 were decreased by the increase of planting density. As planting density increased, contribution of main stem in term of weight grain of panicle and no. of grain increased. However 1^st branch contribution was decreased after the increase of planting density. Highest seed yield was recorded at 30×30 cm of planting density.

Abstract: Background: Globally, the cancer cervix is represent 1/4 of the dominate tumors in the women, and the 1/7 of the whole cancers, where at 2012, it discovered nearly 528 000 novel cases and the mortality was more than 250 000 case. The high incidence of morbidity and mortality mainly referred primarily to the lack of valued screening methods and deprived organized means. Secondary prevention of cervical cancer through early diagnosis and treatment of precancerous disorders in the cervix is concomitant with an overall decrease in both morbidity and mortality caused by cervical tumors. Objective: The goal of the present work was to evaluate the Efficacy and Accuracy of visualization of the cervix using acetic acid (VIA) versus Colposcopic examination for evaluation of suspicious cervix & early detection of cancer cervix. Design Prospective cohort study. Setting: Obstetrics and Gynecology Department, Faculty of Medicine, Al-Azhar University Hospital, (Assiut), Egypt. Methodology: This study included 400 women. The study participants were recruited from Obstetrics & Gynecology outpatient clinic at Obstetrics and Gynecology Department, of Al-Azhar University Hospital (Assuit) Egypt. Visual inspection of cervix after acetic acid application (VIA) and Colposcopic examination, women with positive report on either test were referred for biopsy histopathological evaluation. Results: Our study showed that VIA test has 79.06% sensitivity, 92.54% specificity, 87.2% positive predictive value, 87.3% negative predictive value and 87.3% accuracy. Colposcopy had 80.6% sensitivity, 99.1% specificity, 96.7% positive predictive value, 94.2% negative predictive value and accuracy 94.7%. So, colposcopy was more sensitive and more specific than VIA. The results of this study revealed that women with positive SIL are significantly older, more parus and with longer duration of marriage than women with negative SIL. This is in agreement with some of the risk factors of cervical cancer including advanced age, multiparity, and young age at first intercourse. Conclusion: Colposcopy is a promising alternative to visual inspection of the cervix because colposcopy shows negligible overlap, optimum preservation of cells and decreased inflammatory cells, blood and debris, thus screening and interpretation of cervical smears is easy and simple.

Abstract: Background: Renal Osteodystrophy (ROD) is a collective term describing the mixture of pathophysiological conditions that affect the skeletal system of patients with chronic kidney disease (CKD). It is most evident in patients on hemodialysis (HD), but usually starts early in the course of CKD. Aim of the work: The current work was designed to clarify the role of vitamin k in renal osteodystrophy in hemodialysis patients with and without liver cirrhosis. Patients and methods: This study included 60 patients of chronic renal failure (CRF) on regular hemodialysis with renal osteodystrophy subdivided into two groups according to presence or absence of liver cirrhosis: Group 1: included thirty (30) patients with liver cirrhosis, group 2: included thirty (30) patients without liver cirrhosis. Both groups were selected from Nephrology Units in New Damietta hospital, Al-Azhar University, Kafr Saad and Elzarka General Hospitals, All patients subjected to the following: Full medical history, clinical examination and investigation includes: liver and renal function tests, s calcium, s phosphorus, PTH and s vitamin k, radiological examination include DEXA scan and Abdominal ultrasonography. Results: osteoporosis in group 1 were 21 patients (70%) and group 2 (19 patients (63.3%) there was statistically non-significant difference. osteopenia in group 1 (9 patients (30%) and group 2 (11 patients (36.7%) there was statistically non-significant difference. patients with osteoporosis increased in group 1 than group 2, PTH in group 1 77 ranged from (35 – 550) and group 2 (175 ranged from (40 – 620) there was statistically non-significant difference. PIVKA_II in group 1 (0.27 ranged from (0.10 –3.99) and in group 2 (0.14 ranged from (0.11 –2.99) there was statistically non-significant difference. Conclusion: Patients suffering from renal Osteodystrophy showing deficiency in vitamin K, as revealed by elevated PIVKA-II levels. Vitamin K deficiency is a risk factor for many consequences including osteoporosis, osteopenia and bone fracture so vitamin K status may be a modifiable risk factor. Vitamin K should be assessed in CKD patients to avoid complications.

Abstract: 3D printing is one of the technological advancements that has application in health sciences education. At Macquarie University it has been used for the printing of bones which are then utilized in teaching anatomy. Assessment of accuracy suggest that these prints are accurate copies of the real bones. As such, 3D prints preserve anatomical variation and pathologies, rarely present in commercially produced anatomical models. The bone collection is currently being enlarged and it is planned that the soft tissue and microscopic structures will be printed soon. It is also envisaged that 3D prints will be used in subjects other than anatomy.

Abstract: One of the most important challenges for the new global economy is to find out new sources of bioenergy. Microalgae play an important role as a source of renewable biomass fuel due to its photosynthetic efficiency and the possibility of biotransformation of its carbohydrates into bioethanol. This paper aims to assess first time ever the role of Rhizoclonium sp. (green algae) as a potential substrate for bioethanol production by using different monoculture and co-culture combination of yeast cells under different modes of fermentation SHF and SSF. It also throws light on biomass structure analysis after different pretreatment conditions through Scanning Electron Microscopy (SEM) and analysis of different inhibitors generated after enzymatic hydrolysis of biomass. Activated charcoal and over liming strategies were employed for detoxification of hydrolysates and 5-Hydroxy methyl furfurals as well as sugars were quantified with the help of HPLC. When compared, the maximum ethanol of 23.70 g/l with fermentation efficiency of 46.37% was observed from pretreated biomass under Separate hydrolysis and fermentation (SHF) with Saccharomyces cerevisiae I.

Study On Use Of Pectinolytic Enzyme For Liquefaction Of Feed Substrates-Corn And Cottonseed

Lecturer in Biology, Govt. Senior Secondary School, Singowal in Jind, Haryana (India)

Email: hssonadil@gmail.com

Abstract: Accumulation of reducing sugar and protein at different pectinase dose by Corn and Cottonseed spotted. In substrates weight loss is spotted but no major weight loss is found in corn seeds, In cottonseeds approximately 25% weight loss is spotted. In case of corn seeds maximum sugar and protein released with an enzyme dose. Table 1 in observation showed the amount of sugar and protein released with varying dose of enzyme. In case of sugar test optimum enzyme dose is found to be 1.5 ml while in case of protein test optimum enzyme dose is found to be 1 ml. The variation in results obtained for different substrates can be attributed to the cell wall composition of the substrates which might not be same. The significant amount of reducing sugars found in the reaction filtrates after enzymatic treatment proved the liquefaction of feed substrates. The amount of soluble protein released in the reaction mixture was also appreciable. The proteins are present in the cell walls bound by the strong and fibrous pectins, thus are not available as nutrients. By the action of pectinase these proteins became available and these soluble proteins can be easily estimated in the reaction mixture. This can be explained as incomplete degradation of cellulose resulted in release of large amount of proteins but less sugar. In this substrates were reacted with optimum enzyme dose. All substrates released highest amount of reducing sugar and protein at 45˚C, pectin becomes easily accessible to pectinase for release of more reducing sugar and protein. Results showed that pretreatment of forage prior to feeding can make significant differences. While, from the all reports and researches it was not clear whether the major benefit of enzyme application occur in prefeeding treatment or after the feed enters the rumen of the ruminants or cattles.
