Nature Influences on Architecture Interior Designs

AbstractConcept is on the most important and primary elements during the design process. Through the history, nature has been always a source of inspiration for the human begin in different aspects of their life. Architecture interiors as one of the remarkable features in every society cannot be separated from nature. Nowadays architects and interior designers are constructing buildings without having a specific target or goal which decreases the value of the buildings. Various designers have been using concepts inspired from nature but still there are some missing parts in one of their forms, function, or structure. Therefore, the best solution for the architects and designers to increase the optimization in their design works is looking at the nature in every aspect deeper and try to apply them in their conceptual design of their project which is the heart of the design process while other architects have neglected concepts of nature despite that the surrounding environment and nature always influences human perception. The aim of this research is to understand the relationship between nature and human perception and the role that nature plays in architectural interiors to achieve buildings integrated with the surrounding environment. Also it draws attention of architects to nature and inspiration from nature in different perspectives. This paper presents projects having different concepts in architectural and interior design to make guidelines for designing buildings integrated with nature through example analysis. This paper concludes the importance of making a complete integration between the building exterior, interior and the surrounding nature by using a clear natural concept from the surrounding environment to be solving the design problems

Coinciding Changes in B Lines Patterns, Haemoglobin and Hematocrit Values Can Predict Outcomes of Weaning from Mechanical Ventilation

BACKGROUND: Weaning from invasive mechanical ventilation (MV) is considered as a daily challenging practice in the management of critically ill patients. The use of lung ultrasound and change in haemoglobin and hematocrit during weaning may help to predict weaning outcomes. AIM: We aimed in our study to make a focused view over the changes occurred in lungs during weaning from MV which were detected by lung ultrasound through increase in B lines with the occurrence of weaning induced pulmonary oedema (WIPE), coinciding with this changes the occurrence of hemoconcentration was detected through increase in Hb and HCT values after SBT. PATIENTS AND METHODS: Sixty patients who fulfilled readiness criteria for weaning from MV. Spontaneous breathing trial (SBT) on T-piece for 120 minutes was performed under close hemodynamic monitoring. Lung ultrasound was performed using eight lung zones protocol to detect both the presence and the trend of change in B lines before and after SBT. For all the studied patients, haemoglobin and hematocrit values were checked just before and at the end of SBT. RESULTS: Patient who failed to pass SBT showed significant increase in lung segments showing B pattern, haemoglobin and hematocrit levels (p-value < 0.001 for all) also those patients had significantly higher duration of ICU stay (p-value < 0.001) Despite mortality rate was higher among patients who failed SBT yet it was statistically insignificant (p-value 0.104). CONCLUSION: lung ultrasound and both haemoglobin and hematocrit levels correlate with weaning outcomes

Synthesis and antimicrobial evaluation of some new quinazolin-4(3H)-one derivatives

The oxazolone derivative 1 was synthesized and converted into a hitherto 3,1-benzoxazin-4-one derivative, 3. A series of quinazolin-4-one derivatives 4a-c and 7-11, as well as quinolinone-3-carboxylic acid derivative, 6, and the amide derivatives, 5a,b, were also synthesized via the 3,1-benzoxazin-4-one derivative. The antimicrobial activity of some of the synthesized compounds was examined against three Gram-positive bacteria (Staphylococcus aureus, Streptococcus mutans and Bacillus subtilis), five Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Proteus mirabilis and Acinetobacter baumannii) and one fungi (Candida albicans), using diffusion method. The results showed that compounds 4a, 7, 10 and 11 exhibited significant antibacterial and antifungal activity comparable to standard drugs

Forced degradation of gliquidone and development of validated stability-indicating HPLC and TLC methods

Forced degradation studies of gliquidone were conducted under different stress conditions. Three degradates were observed upon using HPLC and TLC and elucidated by LC-MS and IR. HPLC method was performed on C18 column using methanol-water (85:15 v/v) pH 3.5 as a mobile phase with isocratic mode at 1 mL.min-1 and detection at 225 nm. HPLC analysis was applied in range of 0.5-20 µg.mL-1 (r =1) with limit of detection (LOD) 0.177 µg.mL-1. TLC method was based on the separation of gliquidone from degradation products on silica gel TLC F254 plates using chloroform-cyclohexaneglacial acetic acid (6:3:1v/v) as a developing system with relative retardation 1.15±0.01. Densitometric measurements were achieved in range of 2 -20 µg /band at 254 nm (r = 0.9999) with LOD of 0.26 µg /band. Least squares regression analysis was applied to provide mathematical estimates of the degree of linearity. The analysis revealed a linear calibration for HPLC where a binomial relationship for TLC. Stability testing and methods validation have been evaluated according to International Conference on Harmonization guidelines. Moreover, the proposed methods were applied for the analysis of tablets and the results obtained were statistically compared with those of pharmacopeial method revealing no significant difference about accuracy and precision

Development and validation of spectrofluorimetric method for determination of diflunisal and its impurity

A new sensitive, simple, rapid, accurate and precise spectrofluorimetric method for determination of diflunisal and its impurity is developed. Determination of diflunisal is based on first derivative spectrofluorimetric method, while its impurity can be determined by zero order spectrofluorimetric method. Diflunisal was measured at zero-crossing wavelength 394nm (zero crossing point with its impurity) which was selected for quantification of diflunisal. The impurity was measured directly at 334 nm, using 0.05 M phosphate buffer (pH = 9) as solvent. The analytical signal resulting from first derivative and zero order spectra were measured for diflunisal and its impurity, respectively. Linearity was over the range of 0.1-0.9 μg/mL for both with detection limit of 0.02 and 0.03 μg/mL and quantitation limit of 0.07 and 0.09 μg/mL for diflunisal and its impurity, respectively. The proposed method was validated as per ICH guidelines.The accuracy was checked by applying the proposed method for the determination of the drug and its impurity, the mean percentage recoveries were found to be 99.61±0.911 and 100.41±1.373 for diflunisal and its impurity, respectively. RSD values for repeatability testing were 0.268 and 0.569 and for intermediate precision were 0.224 and 0.259 for diflunisal and its impurity, respectively. The proposed method was effectively applied to analysis of studied drug in its tablet formulation. The results obtained by it were statistically compared with the reported method revealing high accuracy and good precision

Determination of binary mixture of ibuprofen and famotidine by different spectrophotometric methods

Four simple and specific spectrophotometric methods were developed and validated for the simultaneous determination of binary mixture of ibuprofen and famotidine, using unified regression equation. The proposed spectrophotometric procedures including, derivative ratio, ratio subtraction, dual wavelength and mean centering of ratio spectra do not require any separation steps. Accuracy, precision and linearity ranges of the proposed methods were determined and the specificity was assessed by analysing synthetic mixtures of both drugs. The methods were applied to a pharmaceutical formulation and the results obtained showed that there is no significant difference between the proposed methods and the reported one regarding both accuracy and precision

Validated Chromatographic Methods for the Simultaneous Determination of Sodium Cromoglycate and Oxymetazoline Hydrochloride in a Combined Dosage Form

Two chromatographic methods were developed and validated for the simultaneous determination of Sodium Cromoglycate (SCG) and Oxymetazoline Hydrochloride (OXMT). SCG and OXMT are administered in combination for effective treatment of nasal congestion and allergy. The first chromatographic method was based on usingaluminum TLC plates pre-coated with silica gel GF254 as the stationary phase and chloroform: methanol: toluene: triethylamine (5: 2: 4:1, by volume) as the mobile phase followed by densitometric measurement of the separated bands at 235 nm. The second method is a high performance liquid chromatographic method for separation and determination of SCG and OXMT using reversed phase C18 column with isocratic elution. The mobile phase composed of acetonitrile: methanol (2: 1, v/v) at flow rate of 1.0 mL/ min. Quantitation was achieved with UV detection at 220 nm. The validity of the proposed methods was assessed using the standard addition technique. The obtained results were statistically compared with those obtained by the official methods, showing no significant difference with respect to accuracy and precision at p = 0.05
