“…In this context, scientific studies have focused on synthesizing these nanomaterials from non-artificial sources like plants (Aktepe and Baran, 2021), bacteria (Javaid et al, 2018), fungi (Molnár et al, 2018), algae (Parial et al, 2012), seaweeds (Chellapandian et al, 2019), and viruses (Mohmed et al, 2017). In many nanoparticle studies, gold (Au) (Hatipoğlu, 2021), silver (Ag) Umaz et al, 2019;Baran et al, 2021b), zinc (Zn) (Jayappa et al, 2020), nickel (Ni) (Din et al, 2018), iron (Fe) (Devatha et al, 2016), platinum (Pt) (Ramkumar et al, 2017b), selenium (Se) (Abu-Elghait et al, 2021), titanium (Ti), and palladium (Pd) (Gioria et al, 2020) are frequently used metals. Especially silver (Ag) is known to be an important metal suppressing the growth of bacteria.…”

Using biological materials to synthesize metallic nanoparticles has become a frequently preferred method by researchers. This synthesis method is both fast and inexpensive. In this study, an aqueous extract obtained from chickpea (Cicer arietinum L.) (CA) leaves was used in order to synthesize silver nanoparticles (AgNPs). For specification of the synthesized AgNPs, UV-vis spectrophotometer, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction analysis (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), electron dispersive X-ray (EDX), and zeta potential (ZP) analyses data were used. Biologically synthesized AgNPs demonstrated a maximum surface plasmon resonance of 417.47 nm after 3 h. With the powder XRD model, the mean crystallite dimension of nanoparticles was determined as 12.17 mm with a cubic structure. According to the TEM results, the dimensions of the obtained silver nanoparticles were found to be 6.11–9.66 nm. The ZP of the electric charge on the surface of AgNPs was measured as −19.6 mV. The inhibition effect of AgNPs on food pathogen strains and yeast was determined with the minimum inhibition concentration (MIC) method. AgNPs demonstrated highly effective inhibition at low concentrations especially against the growth of B. subtilis (0.0625) and S. aureus (0.125) strains. The cytotoxic effects of silver nanoparticles on cancerous cell lines (CaCo-2, U118, Sk-ov-3) and healthy cell lines (HDF) were revealed. Despite the increase of AgNPs used against cancerous and healthy cell lines, no significant decrease in the percentage of viability was detected.

“…Recently, many approaches have been developed with the biological synthesis method to synthesize different NPs (Umaz and Koç, 2019). The synthesis of NPs is generally carried out by two different synthesis methods, the bottom-up approach and the top-down approach (Gour and Jain, 2019).…”

It is known that construction works cover a fairly wide range of construction works. Public institutions are also trying to meet their needs by conducting tenders, whether it is new construction or major maintenance and repair works. Currently, the Public Procurement Law No. 4734 is the most widely used of the current laws, but the State Procurement Law No. 2886 is preferred for a more limited amount. According to the Public Procurement Law, bidders for construction works tendered are also asked to submit a work experience certificate in order to determine their competence in the professional field. Detailed information is given in the application regulation prepared in accordance with the Law on the possession of this document. Engineers and architects working in the public sector or the private sector as well as public institutions in the construction work of at least 80% of who served in the process of completing the warden, Regional Director, city manager, as manager of a public institution or private sector business partnerships with those who completed the construction work could provide the path to the document as how and to what extent the relevant regulations are described in the document can be edited. Again, the engineers and architects who previously have not completed graduation documents the construction work, five years of work experience for each year to document a certain number ten was given the rights to use, while contracting in the previous years under Carnet Technician, Technician, such as technical officers given the title of this right is not in the business of tendered by Law No. 4734. In addition, since a work experience certificate is not required for construction works commissioned in accordance with Article 22 / d of the Law in accordance with the direct procurement procedure, especially those who work in public institutions located on the borders of metropolitan municipalities using this method may also be eligible for a work completion certificate. jul. In a business partnership, sometimes those who want to have a different work experience certificate can get a completion certificate at the end of the work completed as a junior partner. As a result of the works commissioned in accordance with Article 22 / d, both in business partnerships and in metropolitan areas, the number of those who have the qualification of a contractor increases, but a decrease in qualifications may be observed. In addition to different restrictions on business partnerships, other technical personnel, such as technicians, should also be provided with the legal right granted to engineers and architects, albeit at a low limit, by making new regulations on the subject.

“…The synthesis of NPs is carried out by three methods. These are chemical, physical and biological methods (Umaz and Koç, 2019). Most chemical methods use toxic chemicals and often produce non-polar organic solutions and non-environmentally friendly by-products.…”

“…In addition, physical and chemical methods are not preferred much because of their excessive power consumption, high cost and requiring the use of various devices (Baykal, 2022). Synthesis of NPs by biological method is superior to physical and chemical methods due to its low cost, process simplicity, less chemical use, less energy requirement and environmentally friendly (Umaz and Koç, 2019).…”

Honey; It is a sweet product created by bees by collecting plant nectar and changing its content in their bodies, then taking its final form with maturation in the honeycomb. Apis mellifera, one of the insects of the genus Apis, known as honey bees, is responsible for producing most of the honey consumed worldwide. Since the bees use various plant nectars as raw materials, the variety of honey is very high, and technically, no honey is precisely the same as the other. It can be said that the most important reason for this is that honey is obtained from different plants by being exposed to different climatic conditions. Honey is a significant functional food that people have consumed since the hunter-gatherer periods due to its nutritional content and positive effects on health. Research has shown that beekeeping has been practiced in Anatolia since the Hittites. Flower honey produced in Anzer Plateau is one of the market's most popular and expensive honey. In this study, studies on Anzer honey, the first product with a geographical indication in Rize, where important honey producers are located in Turkey, the second largest honey producer in the world, will be compiled.
