Sedimentation at labyrinth weirs – an experimental study of the self-cleaning process

This article is intended to examine the relationship between Islam and adat in the Bugis traditional wedding procession by using symbolic interactionism analysis. The procession of the Bugis traditional wedding tradition is divided into several parts, namely mappese-pese or mabbaja laleng which is interpreted as a process to find out whether the couple to be married has a fiance or not, this is intended as a form of caution not to propose to a woman who has been proposed. by other people. Madduta is done as a form of appreciation or love among humans. Mappettu ada is meant to reinforce the outcome of the conversation and is intended to elevate the position of women in the procession. Mappacci is meant to carry out the self-cleaning process by using several traditional instruments and using the Koran and praise to the Prophet in the form of reading barazanji as its main foundation and giving leko' is meant as a form of husband's responsibility in providing for his wife. This gives legitimacy that Islam and customs in the tradition of Bugis marriage go hand in hand or a form of acceptance of the Bugis community with Islamic values described in the traditions being carried out.

Anodic Voltammetry

Nine pyrazolone derivatives have been studied by anodic voltammetry using gold self-cleaning rotating electrode (SRE). Voltamograms of good reproducibility are presented. On the basis of voltammetric data a mechanism is proposed for the electrochemical oxidation of sodium 1-phenyl-2,3-dimethyl-4-(N-methylamino)pyrazol-5-one-N-methansulphonate and 1-phenyl-2,3-dimethyl-4-(dimethylamino)pyrazol-5-one in protic medium.

Self Cleaning

In this study, self-cleaning polyester (PET) fabrics were prepared using TiOF2 and hexadecyltrimethoxysilane(HDS) treatment. TiOF2 was synthesized via direct fluorination of a precursor TiO2 at various reaction temperatures. The prepared PET fabrics had superior photocatalytic self-cleaning properties compared with anatase TiO2/HDS-treated PET fabrics under UV and sunlight with 98% decomposition of methylene blue. TiOF2/HDS-treated PET fabrics also had superior superhydrophobic self-cleaning properties compared with anatase TiO2/HDS-treated PET fabrics with a 161° water contact angle and 6° roll-off angle. After the self-cleaning tests of the non-dyed TiOF2/HDS-treated PET fabrics, we prepared dyed TiOF2/HDS-treated PET fabrics to test practical aspects of the treatment method. These PET fabrics were barely stained by tomato ketchup; even when stained, they could be self-cleaned within 4 h. These results suggest that practical self-cleaning PET fabrics with superhydrophobicity and photocatalytic degradation could be prepared using TiOF2/HDS-treatment.
