ABSTRAK Kelangkaan pupuk anorganik di pasaran merupakan salah satu faktor merosotnya hasil pertanian di daerah sekitaran SMK Negeri 1 Lokop. Sehingga penulis yang mengajar di sekolah dengan jurusan Agribisnis Tanaman Pangan dan Hortikultura, mencoba mencari solusi melalui peserta didik dengan menggunakan pembelajaran Project Based Learning. Penulis membuat artikel ini untuk mengetahui dampak pembelajaran Project Based Learning berupa Pupuk Organik Cair (POC) pada peserta didik kelas XI ATPH 1 SMK Negeri 1 Lokop pada khususnya dan masyarakat setempat pada umumnya. Pada pembelajaran tersebut penulis dapat melihat data, bahwa penggunaan pupuk organik cair dapat meningkatkan hasil pertanian petani setempat. Data tersebut menunjukkan kenaikan hasil pertanian pada desa X sebelum menggunakan pupuk organik cair, hasil panen padinya adalah 13-14 kaleng/rante, setelah menggunakan pupuk organik cair maka hasil panen padinya meningkat menjadi 18-20,5 kaleng/rante, jika dipersentase maka akan didapat kenaikan 38%-44%. Selanjutnya hasil dari desa Y sebelum menggunakan pupuk organik cair, hasil panen padinya adalah 10-11 kaleng/rante, setelah menggunakan pupuk organik cair maka hasil panen padinya meningkat menjadi 17-19 kaleng/rante, jika dipersentasekan maka akan didapat kenaikan 70%-80%. Dari data di atas sangat jelas perbedaan yang sangat signifikan antara penggunaan pupuk anorganik dan pupuk organic. Hal ini menunjukkan bahwa para peserta didik mampu menerapkan ilmu yang mereka dapat di sekolah kepada masyarakat setempat, khususnya orang tua mereka. Pembelajaran melalui Project Based Learning sangat berdampak langsung dengan masyarakat setempat. Hal ini terlihat dari data yang didapat penulis.

The face is the most critical component which is clear on first sight for an individual. Soft tissue of the face alongside the fundamental dentoskeletal tissues portrays the facial attributes of a person. Social affirmation, mental well-being, and self-esteem of an individual are related to physical appearance. The impression of a charming face is generally passionate with ethnicity, age, sexual orientation, culture, and character influencing ordinary facial attributes. Strikingly, facial properties are regularly packed in profile. Orthodontic assurance and treatment orchestrating are continuously being established on profiles rather than basically on Angle's concept of molar relationship. It was seen that particular skeletal exact guidelines, proportion of constitution of the soft tissue, and facial solid position can affect the assessment of the profile. One of the uncommon challenges in orthodontics is the treatment orchestrating and the leading body of orthognathic careful cases. These cases require a mix of both orthodontics and orthognathic medical procedure to accomplish an even impediment, appropriate function, and agreeable facial feel. It is obvious in the literature that there are three main types of malocclusions: Class I which includes people who have a normal bite, Class II which includes people who have an overbite, and Class III which includes people who have an underbite. Early analysis of malocclusion is exceptionally helpful to get legitimate straight teeth. Thus, in this paper we built up a straightforward PC supported system using image processing techniques that could help foreseeing teeth impediment. In other words, we take an image of an individual and order it into one of the three primary types: Class I, Class II, and Class III and predict the post-treatments of Class II and Class III. This study gives information which can be used in treatment orchestrating by authorities, for instance, orthodontists, prosthodontists, plastic specialists, and maxillofacial experts, who have the ability to change the soft tissue facial characteristics.

The study included thirty-six isolates of rhizobia bacteria were isolated from the nodules located on the roots of nine types of leguminous family plants that were planted in four areas of the city of Mosul for the winter agricultural season for the year 2020-2019, where they studied the phenotypic and agricultural characteristics of the isolated bacteria in addition to a study of resistance and sensitivity to the isolates of rhizobia bacteria. The study included ten antibiotics, and resistance ratios differed between isolates groups, where the highest resistance rate for residual bacteria isolates was 100% for Nystatin and Amoxicillin, and the lowest resistance was for Tetracycline and Streptomycin, as it reached 22.2%. As for the rest of the antibiotics, there is a difference between that . As for heavy metal salts, all the isolates of rhizobia bacteria under study were resistant to both CdCl2 chloride and CoCl2 cobalt by 100%, while their resistance to nickel chloride NiCl2 was 77.7% and the lowest resistance to heavy metal was mercury chloride HgCl2, reaching 33.3%. The plasmid DNA content was described for the studied isolates, as the results showed that there are two types of plasmid DNA bundles, the first type close to large-scale gel drilling called Mega plasmid represents symbiotic plasmids that carry the genes of contract formation and nitrogen fixation and the second type moves far from the gel drilling and they are sizes small equal representing non-symbiotic plasmids.

In this research new compounds containing quinazolin-4(3H)-one nucleus linked to heterocyclic moieties were synthesized using ethyl (4'-oxoquinazolin-3'-yl) acetate (2) as a synthon. This compound was synthesized via 4-quinazolinone's (1) reaction with ethyl chloroacetate in the existence of K2CO3 as a base and acetone as a solvent. The ethyl α-(4'-oxoquinazolin-3'-yl) acetate (2) was converted to the corresponding hydrazide through its reaction with hydrazine hydrate (85 %). Compound (3) was reacted with two of acyl chlorides to synthesize the diacyl hydrazine compounds (4,5). The compound (5) was cyclized to the corresponding 1,3,4-oxadiazole (6) in presence of phosphorous oxychloride. The formyl derivative (7) of the hydrazide (3) was synthesized via its reaction with formic acid and consequently cyclized by phosphorous oxychloride to the corresponding 1,3,4-oxadiazole (8). The hydrazide (3) was also converted to the thiosemicarbazide derivative (9) by its reaction with ammonium thiocyanate under acidic conditions. Whereas other substituted thiosemicarbazide derivatives (10-12) were synthesized by the reaction of hydrazide (3) with organic isothiocyanate compounds. The resultant compounds (11, 12) were cyclized under basic conditions (4% sodium hydroxide solution) to give 1,3,4-triazole-2-thiole derivatives (13,14), whereas the cyclization of compounds (10-12) was performed under the acidic medium (conc.

Al-iraqi","doi":"10.33899/EDUSJ.2020.127904.1101","DOIUrl":"https://doi.org/10.33899/EDUSJ.2020.127904.1101","url":null,"abstract":"In this research new compounds containing quinazolin-4(3H)-one nucleus linked to heterocyclic moieties were synthesized using ethyl (4'-oxoquinazolin-3'-yl) acetate (2) as a synthon. This compound was synthesized via 4-quinazolinone's (1) reaction with ethyl chloroacetate in the existence of K2CO3 as a base and acetone as a solvent. The ethyl α-(4'-oxoquinazolin-3'-yl) acetate (2) was converted to the corresponding hydrazide through its reaction with hydrazine hydrate (85 %). Compound (3) was reacted with two of acyl chlorides to synthesize the diacyl hydrazine compounds (4,5). The compound (5) was cyclized to the corresponding 1,3,4-oxadiazole (6) in presence of phosphorous oxychloride. The formyl derivative (7) of the hydrazide (3) was synthesized via its reaction with formic acid and consequently cyclized by phosphorous oxychloride to the corresponding 1,3,4-oxadiazole (8). The hydrazide (3) was also converted to the thiosemicarbazide derivative (9) by its reaction with ammonium thiocyanate under acidic conditions. Whereas other substituted thiosemicarbazide derivatives (10-12) were synthesized by the reaction of hydrazide (3) with organic isothiocyanate compounds. The resultant compounds (11, 12) were cyclized under basic conditions (4% sodium hydroxide solution) to give 1,3,4-triazole-2-thiole derivatives (13,14), whereas the cyclization of compounds (10-12) was performed under the acidic medium (conc. H2SO4) to give 2substituted amino-1,3,4-thiadiazoles (15-17). On the other side, the hydrazide's (3) reaction with isocyanate compounds affords the semicarbazide compounds (18,19). These compounds were cyclized under the basic condition to afford 1,3,4-triazol-2-ol compounds (20,21).

A chatbot is a computer program which is designed to interact with users and answer questions. Nowadays, chatbots are one of the most common systems that are used in many fields and by different companies to achieve different tasks. Cloud computing is gaining increasing interest. A myriad of fields and applications have been developed based on cloud computing. In this paper, a college chatbot was developed and implemented to assist students to interact with their college and ask questions related to faculty, activities, exams, admission, amongst other tasks. Text similarity algorithms were adopted to achieve the proposed system. More specifically, cosine similarity and jaccard similarity algorithms were used to find the closest question in the dataset. Firebase real-time database, which is one of the Google cloud services, was used as a connector channel between users and the chatbot server. Experiments were conducted to evaluate the performance of cosine similarity and jaccard similarity methods, and to compare the results of both. In addition, real-time database was also evaluated as a chatbot connecter channel.
