Authors: Sirait Judyanto
Published: May 2024

Gaya merupakan salah satu konsep dasar dalam fisika yang digunakan untuk menyelidiki gerak sebuah benda. Konsep gaya ini digunakan dalam berbagai materi fisika seperti gerak lurus, gerak melingkar, gerak parabola, gerak rotasi, momentum dan impuls, usaha dan energi, dan bahkan dalam listrik statis. Dengan demikin konsep gaya ini sangat penting untuk dikuasai sehingga diajarkan sejak sekolah dasar hingga perguruan tinggi. Penelitian ini bertujuan untuk menganalisis pemahaman mahasiswa tentang gaya. Jenis penelitian survey dilakukan untuk mengukur kompetensi representasi mahasiswa dengan tiga bentuk representasi yakni diagram gaya, persamaan matematis, dan deskripsi konsep. Sebanyak 92 orang mahasiswa menjawab tes kompetensi representasi gaya yang terdiri dari 30 butir pertanyaan. Pemberian skor untuk jawaban mahasiswa adalah 1 untuk jawaban benar dan 0 untuk jawaban salah kemudian dikonversi ke skor 100. Hasil analisa data menunjukkan bahwa skor rata-rata kompetensi representasi mahasiswa adalah 34,17 dengan kategori pemula. Sebesar 32% mahasiswa mendapat skor pada kategori menengah (intermediate) dan 68% mahasiswa masih berada pada kategori pemula (novice). Skor mahasiswa paling tinggi diperoleh pada situasi balok dalam keadaan diam baik dalam permukaan horijontal dan bidang miring. Sementara skor mahasiswa yang paling rendah adalah situasi balok bergerak dengan kecepatan konstan untuk kedua bidang permukaan. Kompetensi representasi mahasiswa mengubah ke persamaan menjadi yang paling rendah dibandingkan dengan deskripsi dan diagram gaya.

Published: May 2024

ICT can be regarded as the combination of "informatics communication" and other technologies, especially communications technology. Informatics refers to the study of information, computation, and communication. This can apply to artificial systems such as computers or natural systems such as brains, genes, and living cells. Informatics technology refers to the technological application of informatics in society and is the study of the behaviour and structure of any system that generates, stores, processes, and presents information. A simple random sampling technique was used. The total sample size was 100. The questionnaire method of data collection was adopted to elicit information on the socio-economic characteristics of the farmers, their perceptions of ICT, the accessibility of ICT, and factors that affect the use of ICT technology by poultry farmers. The collected data was subjected to descriptive statistics (such as frequency tables and percentages) for analysis. The result showed that 61% of the farmers are actively participating in poultry farming; it also showed that extension service delivery made it easier for the farmers to get ICT information; and it also showed that high costs (71% of the time) were the major constraint to the adoption of ICT by the smallholder poultry farmers in the study area.

Published: May 2024

The meat preservation has positive effect on economy due to it prolongs the shelf life of the meat and also improve public health due to inhibition growth of microorganisms. In meat preservation Methods there is different methods that are being used for meat preservation. Since the man started to utilize the meat, he started to preserve it for later uses. Means of meat preservation that are used for meat preservation as meat Drying, meat Canning, meat Smoking, meat Freezing, meat Chilling, meat Curing, meat Salting, meat Fermentation and meat Pickling and meat Irradiation. Meat drying is the oldest meat preservation method that is still being used. Meat drying is also known as dehydration. Bacteria and enzymes only multiply at a certain level of moisture content, in meat drying we reduce the moisture content to 10-20% by weight and hence the enzyme remain inactivated. In the past meat was dried by sun meat drying method but now oven and dehydrators in practice. Now it’s easy to dry the meat at home with the help of stove and oven. By process, firstly, cut the meat into thin narrow meat strips then boil meat strips at high temperature that’s the bacteria could be killed, after boiling for 5-10 minutes’ bake in the oven. Through this method of meat preservation we can preserve meat for 1-2 months in the air tight containers.

illagers of Chhina, Rawalpindi have been migrating overseas since the 1950s.Their households persist much intensity for development once because of multiple socio-economic factors i.e., limited natural resources and less productivity in agriculture. Unemployment, remittances, and, pleasing social status have played a part in the decision for overseas migration. 47.4 % of villagers as skilled and unskilled workers have been serving in eight differentcountries for a couple of decades. Overseas migration has been influenced by the interrelation of socio-economic, cultural, and kin ties. An altruistic spin opted by villagers to choose a strange region to meet hopeful socio-economic sustainability for their families in the native countries. They have strived for the well-being of their native dependents through remittance. The bulk of money in the form of remittances established a sustainable resource for the uplift of the deprived condition of migrant households.
Phylogenetic position of Discolaimium (Nematoda: Dorylaimida) from South Africa using 28S rDNA
Authors: AMINISARTESHNIZI MEHRNOUSH
Published: May 2024

Dorylaim nematodes inhabit soil and are predatory, primarily feeding on other nematodes. This predatory behaviour positions them as a potential natural solution to combat plant-parasitic nematodes. By preying on their fellow nematodes, they contribute significantly to ecological diversity. Therefore, this molecular study was conducted in 2022 at the University of Limpopo to identify the soil nematodes from South Africa using a 28S rDNA marker. The recovered nematode was extracted using the tray method. The Chelex method was used to extract DNA, and the nematode was identified as Discolaimium. Afterward, 28S rDNA was amplified using specific primers to identify the nematode. The Nblast analysis based on the small subunit ribosomal DNA showed that South African Discolaimium has a 97% similarity (MG921263) with the Chinese population of Discolaimium. Phylogenetic analysis using maximum likelihood placed this species with those molecularly identified as Discolaimium in the same clade with highly supported (100) bootstrap values. In conclusion, this species was properly identified using 28S rDNA. However, other DNA markers are recommended to understand the Discolaimium phylogeny better.

Authors: Shafran S. A. , Kozeicheva E. S.
Published: May 2024

A review of publications devoted to the study of the effect of mineral fertilizers on the yield of various varieties of grain crops on various soils is presented. At the same time, special attention is paid to the assessment of the equity participation of various factors in the formation of their productivity. It was found that the greatest contribution to the formation of yield falls on soil fertility, which on sod-podzolic highly cultivated soils amounted to 68–90%, depending on nitrogen doses and varieties, and the share of nitrogen fertilizers varied from 10 to 32%. The coefficient of variation between varieties in terms of yield was in the range of 16–20%. The increase in winter wheat yield from nitrogen application in comparison with the standard Zarya variety ranged from 64 to 146%. In the experiment of VNIPTIHIM, where 33 varieties of winter wheat and 17 varieties of spring barley were tested, the share of the soil fertility factor in the formation of the winter wheat harvest was 81–82, spring barley – 83–89%, the contribution of the variety, respectively, was 6, 13 and 6%.
On ordinary chernozem, its participation in the formation of winter wheat yields slightly exceeded the indicators of sod-podzolic soils, as well as the contribution of fertilizers, despite the introduction of higher doses of mineral fertilizers. The variation in yield depending on the variety was 5–6%. In the experiment on leached chernozem, which was characterized by average agrochemical cultivation, the most productive variety of winter wheat showed a yield 2 times less than that of the previously considered varieties.

Morphological studies of farm animals are most often conducted using simple preparation and staining techniques. The study of the processes of embryogenesis, postembryonic features of the development of organs and tissues, as well as the effect of various substances remains to be elucidated not only using histochemical and immunohistochemical staining methods, but also using RNA in situ hybridization and transcriptome in situ sequencing. Aspects of many cellular and tissue processes for cattle, pigs and chickens in the context of comparative physiology have not yet been studied. The high productivity of farm animals is associated with the intensive functioning of all organs and systems of the body. The influence of the agricultural management of farm animals and its consequences on the development of an organism in ontogeny deserve a separate area of research from the point of in situ gene expression. Despite rapid development of transcriptome sequencing technologies, which result in the discovery of new candidate genes for many processes, RNA in situ hybridization remains the gold standard for their validation. This review briefly presents modern techniques and their modifications for studying in situ gene expression. Transcriptome studies that have been implemented in cattle, pigs and chickens as model organisms include: in situ RNA hybridization using ZZ-probes, tyramide signal amplification, hybridization chain reaction, digoxigenin-labeled probes, RT-PCR, single cell transcriptome sequencing, in situ transciptome sequencing. This paper is a review of the results of studies on cattle, pigs and chickens. The results of research in this area are relevant for understanding the features of adaptation mechanisms at the transcriptomic level in highly productive animals under industrial conditions in order to search for new markers of valuable agricultural traits. It should be noted that in literature there are very few studies using RNA in situ hybridization, despite the availability and simplicity of the method.

Published: May 2024

In this study, a gas discharge electroacoustic transducer (GDEAT) based on a pulsed electric discharge in the air under atmospheric pressure has been investigated. By evaluating acoustic pressure and recording amplitude-frequency characteristics of membranes, the acoustic characteristic of GDEATs have been obtained in the frequency range from 40 Hz to 4 MHz. The electro-thermo-acoustic processes have been studied in gas discharge systems of an open type where the electrode space is in a direct contact with the ambient. Some features of using the above-mentioned GDEATs in nondestructive testing (NDT) of materials have been demonstrated. It has been shown that, on one hand, the wear of both electrodes and insulation limits a work life of a transducer electrode system, but, from the other hand, this may lead to deposition of micro-particles on the surface of an object under test. The wear of electrode systems was evaluated quantitatively, and the results of the chemical analysis of deposited micro-particles have been presented. The use of a GDEATs for non-contact stimulation of local resonant vibrations in subsurface defects and visualizing vibrations by means of laser dopler vibrometry has been shown in the case of NDT of a glass fiber composite.

Published: May 2024

Currently, foreign DNA or RNA sensor proteins, which play an important role in innate immunity, are of great interest as a new avenue for cancer immunotherapy. Agonists of these proteins can activate signaling cascades in immune cells that cause the production of cytokines, in particular type I interferons, which have a powerful cytotoxic effect. This review examines the functioning of cytoplasmic nucleic acid sensors such as cGAS, STING, IFI16, AIM2, DAI, DDX41, DNA-PK, MRE-11, and TREX1 involved in activating the production of various cytokines.
Comparison of the cytogenetic effects of a pulsed magnetic field and gamma radiation on meristem cells of onion seed sprouts (Allium cepa l.)
Authors: Aldibekova A. E. , Styazhkina E. V. , Tryapitsyn G. A. , Pryakhin E. A.
Published: May 2024

The effect of a pulsed magnetic field (PMF) on meristem cells of onion seedlings was compared with the effects of acute gamma irradiation using the allium test. It was found that a pulse with a carrier frequency of 1.8 MHz, a pulse repetition rate of 28 kHz, and a magnetic field induction of 75 mT per pulse leads to an increase in the mitotic index, mainly due to an increase in the proportion of cells in the prophase, an increase in the frequency of cells with chromosome aberrations in the ana-telophase and does not affect the frequency of cells with micronuclei. It has been suggested that UTI causes nonspecific oxidative stress in plant cells, accompanied by a delay in the cell cycle at the check point (G2/M) and induction of DNA damage. According to these indicators, the PMF resembles the effect of ionizing radiation in doses of 0.05–0.5 Gy.

Published: May 2024

The number, species composition and taxonomic structure of fungal biota in the groundwater of natural springs and wells in the Moscow region were determined by сultural method. The number of fungi was low, on average from 10 to 300 colony-forming units (CFU) in 1 liter of water. 6–16 species were isolated from the water of one source or well, and totally 46 species were isolated from 6 studied objects. These were representatives of phylum Mucoromycota class Mucoromycetes (Absidia cylindrospora var. nigra, Mucor circinelloides, M. hiemalis,Rhizopus stolonifer), phylum Ascomycota class Eurotiomycetes (15 species of the generaAspergillusandPenicillium), Sordariomycetes (13 species of the generaAcremonium, Chaetomium, Fusarium, Myrothecium, Plectosphaerella, Trichoderma), Dothideomycetes (Alternariaalternata, A. nobilis, Amorocoelophoma cassia, Cladosporium cladosporioides, C. sphaerospermum) and – Saccharomycetes (Candida solani, C. zeylanoides, Galactomyces pseudocandidus) and phylum Basidiomycota class Tremellomycetes (Mrakia gelida, Vishniacozyma victoriae) and Agaricomycetes (Phlebia acerina, Psathyrella candolleana, Thanatephorus cucumeris). The established taxonomic structure of fungal biota in the waters of natural springs and wells of the Moscow metropolis is similar to that found in the groundwater of other regions, including of groundwater at the depths of several hundred meters. The possibilities of adaptation of micromycetes to existence in ground water, the sources of its contamination and the need for mycological criteria for assessing water quality are discussed.
Emission of gaseous nitrogen oxides in soils of boreal forests (review)
Authors: Razgulin S. M.
Published: May 2024

Denitrification losses of nitrogen-containing gases in the biome of boreal forests are discussed. In the soils of coniferous and deciduous forests of Western Europe, 0.57 ± 0.2 and 1.0 ± 0.2 kg N-N2O/ha/ year are lost during denitrification. In North America this figure was 0.35 ± 0.29 kg N-N2O/ha/yr for all stands. The emission of N2O from forest soils correlated with the input of nitrogen from the atmosphere withr= 0.47 in coniferous forests and withr= 0.68 in deciduous plantations, returning to the atmosphere up to 30% of the nitrogen supplied with atmospheric precipitation. With a high input of nitrogen from the atmosphere, the emission of nitrogen-containing gases reached 20 kg N /ha /yr. Of these, NO, N2O, and N2accounted for 21, 15, and 64%. Measurements of NO and especially N2emissions remain very rare, leading to incomplete estimates of denitrification losses. Denitrification remains the most complex process in the nitrogen cycle, with no definitive methods for measuring it.

Published: May 2024

We performed a quantitative and qualitative assessment of the dynamics of gap formation in the canopy of intact old-growth polydominant broadleaved forest in a permanent sample area in the Kaluga Zaseki Nature Reserve. Digital elevation models were obtained from aerial survey data of the forest in 2018 and 2021, from which gap diagrams of several elevation classes were constructed. The resulting schematics were expertly analyzed using orthophotomosaic survey data and gap areas were estimated. We conducted a sample ground survey of gaps and regression analysis of the relationship between relative gap area and stand species composition from the primary enumeration data. It was shown that the phenophase at the time of the survey can significantly change the estimate of gap areas, and the height of the stand in the gap cannot serve as a reliable indicator of its age. It was also found that aerial photography reveals a more complex gap structure than ground-based surveys.

It is emphasized that the performance of a distributed information system depends on many factors, including the size and structure of the database, the hardware used, the number of replicas and their geographical location. A conclusion was made about the perspective of the concept of non-relational NoSQL databases and it was concluded that it was proposed for efficient storage and provision of quick access to large volumes of information, the so-called Big Data, which cannot be achieved using traditional relational database management systems. The essence of the concept of “NoSQL database” is revealed and the currently existing difficulties in using large systems are named. In NoSQL databases, multiple replication (copying) of a record is used to ensure high fault tolerance. But there is a significant drawback for them, because these systems do not support the mode of conducting transactions and blocking, so there is a problem of data reconciliation. It is emphasized that NoSQL databases mainly use two methods of placing and updating the time of the data consistency process in NoSQL: according to the principle of “master-slave” and “ring”. A model of strong data reconciliation in NoSQL is described and an example of time optimization for the healthcare system is considered. It has been established that even with large values of the intensity of receiving requests for reading λ, the waiting time does not exceed 3 ms. However, when performing analytical queries, this time can increase, so with large N and high intensity of incoming read requests, this time can reach 7 ms.

Published: May 2024

The low awareness and behaviour of environmental care and the increasing cases of environmental damage caused by human behaviour are the background of the research. Environmental problems caused by humans continue to occur and increase every year, ranging from the destruction of ecosystems to the emergence of waste that damages the environment. Environmental care behaviour is an important part that must be owned by every human being on earth, because this is related to the survival of every creature, both plants, animals, and other humans. This study aims to determine the effect of students' participation in environmental education programmes on pro environmental behaviour. This research is a type of quantitative research with survey method. Data collection techniques were obtained by means of observation and questionnaires. The research subjects were 5th grade elementary school students totalling 45 people. Data analysis was conducted using paired sample t test to measure the influence between variables and linear regression analysis to measure the amount of influence given. The results showed that there was a positive influence of student participation on pro environmental behaviour with sig. 0.004 < 0.005, with rcount = 0.419 > rtable = 0.294 so that it can be interpreted that the higher the participation of students in the environment, the better the environmental care behaviour, where R2 = 0.175 shows the influence of student participation with pro environmental behavior by 17%, while 83% is influenced by other factors. From these results, it shows that students' participation in environmental education programs plays an important role in supporting environmental care behaviour that leads to attitudes to protect the environment. The implication of the research is as a database and evaluation of education, especially in the environmental care behaviour of elementary school students.
