  Correlation coefficient, Regression analysis, Sugarcane transplanting, bud chips.
  The present study was carried out in a privet farm in El-Shaghap Region, South Esna of Luxor Governorate, Egypt (latitude of 25.30°N and longitude of 32.30°E). The work was conducted during the two plant-crop seasons of 2017/2018 and 2018/2019 to study the sugarcane planting using bud chips and conventional methods. Four sugarcane varieties G.T.54-9, G.84-47, G.2003-47 and C.57-14 were tested in this study. The experimental design was a split plot design with four replications. The four varieties were randomly distributed to the main plots and the two planting methods (conventional method and bud chips) assigned as sub-plot (42 m2). Each plot contains six rows with the length of seven meters/row and one meter of row width.
The results indicated that unique and high positive estimates of correlation coefficients were recorded between seeding survival % and each of millable cane length, millable cane weight, cane yield/ fed, brix, sucrose content, purity %, sugar recovery %, pol and sugar yield/fed across bud chips planting method. Otherwise, the previous results were not found for conventional planting method, reflecting the remarkable effect of bud chips planting method on correlation coefficients corresponding to the seeding survival produced using that method. Brix recorded high and positive correlation with each of sucrose %, purity %, sugar recovery %, pol % and sugar yield/ fed across both planting methods.
It is remarkable results that the correlation coefficients between each of sucrose %, purity %, sugar recovery % and pol % were equal or close to unity, reflecting the very strong genetic make-up of those traits.
Regression analysis revealed that the predictors traits, i.e., sugar yield/fed., millable cane diameter, millable cane length, seedling survival%, millable cane weight and number of millable cane/fed. could be used as powerful selection criteria for high cane yield/fed. Moreover, the predictors traits, i.e., cane yield/fed, stalk length elongation, millable cane length, millable cane diameter, number of millable cane/fed, stalk survival%, pol%, brix% and sucrose% could be used as powerful selection criteria for high sugar yield/fed.

  Sugarcane molasse; Oxalic acid; Formic acid; Chelating agent; Permanganate; Kinetics.
  Oxalic acid in alkaline medium was quantitatively synthesized using sugarcane molasse oxidation (SCM) by potassium permanganate as oxidizing agent. The produced compound was identified using Fourier Transform Infrared (FT IR), mass spectra and with by reaction with 2,4-dinitrophenyl hydrazine and hydroxylamine reactions have been identified as the oxidation product (oxalic acid), which gives negative results in 2,4-dinitrophenyl hydrazine and hydroxylamine. It has been found that the oxidation portion has a strong chelation affinity with most mono- and divalent complexes that provide stable high chelating agents and therefore one of the most abundant organic acids in the plant. Again, the formic acid was prepared from the result of oxidation (oxalic acid) and by FT IR.

  Sugarcane bagasse, fungi, cellulases, xylanases,enzymes
  Lignocelluloses of sugarcane represent a precious and cheap source for enzyme production by several fungal species. In the present study 25 samples of sugarcane bagasse were analyzed for their fungal content. The growing fungal strains were then screened for their abilities to produce cellulolytic and xylanolytic enzymes in solid and broth cultures. A total of 62 fungal species belonging to 31 genera were identified from the tested samples. The most prevalent genera were Aspergillus and Fusarium being isolated from 96% of the tested samples. Mucor, Penicillium and Talaromyces colonized 45% - 52% of bagasse samples.The most prevalent species were A. flavus, A. niger and F. oxysporum. Internal trans. Spacer (ITS) sequences of rDNA confirmed the identification of two new records (Ceratocystis adiposa, Phaeoacremonium viticola) in addition to Sarocladium kiliense, Stachybotrys chartarum and S. elegans. Cellulolytic activities were detected in solid cultures of 73.7% of fungal strains with the most active being Aspergillus tamarii, Exserohilum rostratum and S. chartarum. Xylanolytic activities were exhibited by59.8% of fungal strains and the active xylanase producers were A. niger, A. tamarii, A. tubingensis, C. adiposa and E. rostratum. Spectrophotometric measurements using dinitrosalicylic acid (DNS) reagents howed high cellulase concentration in broth cultures of S. chartarum followed by A. niger, C. adiposa and S. elegans (10.2- 52.0 IU/ml). The relative activity of fungal cellulase ranged from 0.2-1.7 IU/ml/min whereas the specific activity fluctuated between 2.471-14.590 IU/mg protein. Xylanase concentration, relative and specific activities were markedly high especially in cultures of A. niger (360.6 IU/ml, 32.0IU/ml/min. and 64.611 IU/mg protein, respectively).

  A low cost adsorbent has been tested for its adsorption ability to remove a hazardous dye from textile wastewater. The paper assess the results pertaining to the investigation conducted on the removal of the azo sulphonated dye, direct red 81 by adsorption on the filter cake waste as adsorbent. Adsorption studies were carried out in batch mode to examine the influence of various parameters affecting the removal efficiency of the adsorbent. Isotherm data were found to fit well with the Frendlish adsorption mode .from the estimated mean adsorption energy of 3.8 kJmol-1 according to the D-R isotherm model and fitting with the pseudo second–order rate equation, we concluded that the adsorption process of the dye onto filter cake is a physical process with some contribution from chemical adsorption

  Freshwater quality, Nile river water, Drinking water treatment, Freshwater bacterial count
  The Nile River is the longest in Africa and is one of the most important sources of freshwater. Water specifications vary along the course of the river, which represents the main source of drinking water in Egypt, with depends on the treatment of raw freshwater by conventional plants to get rid of the main pollutants of freshwater, such as suspended particles (turbidity) and microorganisms, therefore assessment of the characteristics of freshwater of the river over long period and studying it opens many horizons for establishing of new techniques for treating the freshwater.
The main objective of this study is to monitor the Nile River over a period at the study area Assiut-Egypt, as this study shows that the Nile River contains large quantities of bacteria with an average 1645 CFU/ml throughout the year in different seasons those affects the numbers of these bacteria, in addition to the river contains moderated concentrations of total dissolved solids with an average 216 ppm, and the average turbidity is about 4.7 NTU, while the average value of pH was 8.2, as well as confirming the low concentrations of iron as the average was 0.04 ppm, moderate concentrations of chloride as its average was 15 ppm, and low concentrations of ammonia as the average was 0.06 ppm. Therefore, this study is an assessment of the Nile River water specifications to prove that the freshwater required to be treated of the non-complied values of bacteria and turbidity concerning the Egyptian drinking water standards.

  Groundwater, Sorted Sand, Organo kaolinite, Chitosan, Composite, Sulfate, Egyptian, Assiut
  In Upper Egypt, especially in the limestone carbonates scarp, groundwater is contains sulfate salts, which are considered more difficult to remove by conventional treatment plants for freshwater, used for drinking, domestic and industrial purposes. The study aims to prepare a reasonable adsorbent composite from Egyptian organo-kaolinite and prepared chitosan to remove the excess of sulfate ions from Assiut groundwater wells. Therefore, the modified organo-kaolinite was treated with prepared modified chitosan as a composite media filtration to treat groundwater. In this study, the prepared chitosan was characterized by using X-ray diffraction (XRD). FTIR and scanning electron microscopy (SEM) and its efficiency for removing sulfate have been tested through batch and experimental column studies.
The results revealed that the adsorption of sulfate ions is optimum at pH range 4–8. The maximum sulfate ions adsorption capacities were found 2.88 mg/g, after about 65 min contact time. The regeneration study illustrated that the prepared composite could be used up to 5 times with maximum sulfate ions percentage removal of 62.33%, achieved after the 5th cycle. The Chitosan modified kaolin clay mineral showed higher adsorption capacity towards sulfate ions with other adsorbents as in the literature.
