Средний образец методом квадратирования отбирается следующим образом: обобщённый образец расстилается на гладкую поверхность в форме тонкого квадратного слоя. После чего слой зерна выравнивается ребровидной согнутой и односторонне гладкой деревянной планкой, и держа с двух сторон, образец зерна разделяется посередине (по диагонали).

Ҳар бир ҳудуд тупроқ-иқлим шароитини ҳисобга олиб, бир мавсумда ўсимликшунослик маҳсулотларини кўпайтириш имкониятлари аниқланмоқда. Соя дуккакли ўсимликларга хос равишда ўз илдизлари орқали ҳаводан соф азотни ўзлаштириб олади ва тупроқни экологик тоза биологик азот билан бойитади. Ўсимлик ўсув даврида ўзи учун ҳам, ўзидан кейинги ўсимлик учун ҳам маълум миқдорда азот қолдириб кетади.

The emergence of SARS-CoV-2, causing Covid-19, posed a global threat at the end of 2019, with far-reaching consequences for humanity. Despite extensive efforts to combat the disease, Covid-19 continues to spread, accompanied by the emergence of new, unfavorable variants, and an overburdened healthcare system. This study delves into the intricate interplay between Covid-19 and individuals with pre-existing chronic organ and systemic disorders, shedding light on the patterns of adverse outcomes and prognosis. Comorbidities, notably arterial hypertension, obesity, chronic lung disease, diabetes mellitus, and other cardiovascular conditions, have been strongly associated with severe Covid-19 cases and complications. These conditions often align with the concept of metabolic syndrome, a cluster of disorders encompassing arterial hypertension, obesity, and hyperglycemia. Metabolic syndrome's influence on Covid-19 outcomes is further compounded by concurrent chronic kidney, respiratory, and cardiovascular diseases. The study emphasizes the role of adipose tissue in exacerbating the impact of metabolic syndrome. Visceral fat accumulation, a hallmark of obesity, intensifies the systemic effects of angiotensin II, culminating in microcirculatory disruptions and vascular elasticity loss, potentially leading to cardiovascular complications. SARS-CoV-2 enters the body through ACE2 receptors, found in various tissues, including the respiratory tract, lungs, heart, central nervous system, kidneys, and adipose tissue. The presence of ACE2 receptors in adipose tissue facilitates viral entry, making the study of metabolic syndrome even more crucial for Covid-19 patients. This research involved 147 individuals over 18 years of age, classified into three groups: Covid-19 patients with coronary artery disease (CAD) and metabolic syndrome, Covid-19 patients with CAD but without metabolic syndrome, and healthy individuals without clinical signs of CAD or metabolic syndrome. The study utilized clinical, instrumental, and laboratory data to establish correlations. Among the findings, women with CAD and Covid-19, combined with metabolic syndrome, exhibited a higher prevalence of painless coronary artery disease, often linked to latent type 2 diabetes mellitus and diabetic neuropathy. Male patients in this group were more likely to be smokers and had earlier CAD onset. Notably, Covid-19 prompted the first diagnosis of type 2 diabetes mellitus in 24% of cases among patients with CAD and metabolic syndrome. Furthermore, Covid-19 exacerbated lipid profile parameters, resulting in a higher atherogenic index and increased triglyceride levels. Patients with metabolic syndrome demonstrated a higher prevalence of hyperlipidemia and dyslipidemia, characterized by elevated triglycerides, decreased HDL, and increased LDL. Echocardiological examinations revealed significant differences in left ventricular geometry, with a higher prevalence of concentric LV myocardial hypertrophy in patients with CAD and metabolic syndrome. In summary, this study underscores the critical role of metabolic syndrome in shaping the clinical outcomes of Covid-19 patients with pre-existing coronary artery disease. It highlights the importance of managing comorbidities, particularly obesity and hyperglycemia, in mitigating the progression of Covid-19 and associated complications.

Gʻoʻzaning C-6524 naviga biostimulyator xususiyatiga ega bakteriyalar hamda sianobakteriya shtammlarining taʻsir o’rganildi. Bunda sianobakteriya N. calcicola 32 va bacteriya A. chroococcum 44, A. brasilense 4-13, B. subtilis CКБ256, B. thuringiensis 93, B. thuringiensis 1фo shtammlarini g’o’za o`simligi o`sishi va rivojlanishiga ta`siri tahlil qilindi. Tadqiqotda keltirilgan sianobakteriya hamda bakteriyalarning faoliyati natijasida gʻoʻzaning biometrik koʻrsatkichlari taqqoslanib o`rganilganda nazoratga nisbatan ildiz va poya biomassasi va uzunligi ortganligi qiyosiy tahlil qilindi. O`rganilgan mikroorganizm shtammlari orasida N. calcicola 32 g`o`za poyasini nazoratga nisbatan 7,5 sm, B. subtilis CKB256 shtammi ildiz uzunligini nazoratga nisbatan 11,2 sm ga oshirgan. G`o`za o`simligining poya biomasssasiga o`rganilgan shtammlar orasidan nazoratga nisbatan eng faol B. subtilis CКБ256- 3,13 marta, A. chroococcum 44 shtammi esa - 2,9 marta ko`p hosil qilgan. Ildiz biomassasini nazoratga nisbatan A. chroococcum 44 shtammi -2,9 marta va B. thuringiensis 93 shtammi esa 1,31 martaga oshirganligi aniqlandi.
