Published: April 2022

The analysis of biological features of Centaurea cyanus and Agrostemma githago as well as their variability and diversity, depending on the occupied habitats, is presented in the paper. For this purpose, 30 specimens were randomly collected from each studied habitat – stubblefields, winter cereals and spring cereals and put to the morphological analysis with respect of the height of plant, number of ramifications of 1st and 2nd categories, length of the ramifications, number of inflorescences, number of seeds at one plant, a thousand-seed weight and aerial dry mass of plant. The values of features were used for statistic calculations. Centaurea cyanus and Agrostemma githago populations collected in Siedlecka Upland habitats revealed internal variability in respect to all analyzed features. Specimens of Centaurea cyanus differed from each other with regard to the above mentioned features, depending on habitat type. Significant differences between populations occurring in winter cereals, depending on the soil conditions as well as between individuals originating from rye cultivations and stubble-fields in identical soil conditions, were demonstrated. Moreover, no significant differences between populations developing in winter and spring cereals on the analogical soil type were found.
No significant differences between the majority of the investigated features of Agrostemma githago specimens, developing in rye cultivations and in stubble fields in the same soil conditions were noted. There were also no significant differences in features of the studied species between 2005 and 2006 – no interactions between year of studies and habitat type were observed.

The results of investigations carried out between 1997 and 2000 on growth stages of Apera spica-venti in winter rye plantations are presented in the paper. Various methods of presowing cultivation of soil (using plough and cultivator) and diverse doses of nitrogen (50 kg N . ha-1 and 150 kg N . ha-1) were applied. Meteorological conditions had a strong influence on the development of the studied species in each year of the experiment. Particular individuals in Apera spicaventi population had a different pace of growth and development in advantageous vegetation conditions. Replacement of plough cultivation using a cultivator resulted in decrease of intensity of Apera spica-venti germination however, a larger number of individuals reached full vegetation phase (BBCH 30 – 45) and seed maturity phase (BBCH 80 – 89) using cultivator; however, only the effect of the method of cultivation on the number of individuals, reaching full vegetation phase was statistically proved.
Both germination and reaching more advanced development phases proceeded more intensively in conditions of high nitrogen fertilization; however, the differences were not significant statistically.

The influence of water extracts from Apera spica-venti on germination capacity and energy of winter rye and winter triticale was evaluated in the study. The length of the first leaf and the longest primary root was estimated on cereal seedlings after eight days.
The experiment was performed on Petri dishes in two independent series, 5 replications each. Water extracts from dry and fresh matter of above ground parts of Apera spica-venti were used. The extracts were prepared using 2, 4, and 8 g of dry and fresh weed matter per 100 ml of distilled water. Dishes wetted only with distilled water were the control objects. Results were statistically processed by means of variance analysis. Differences between the mean values were estimated applying Tukey’s test. Study results related to germination energy and capacity were transformed onto arcsin x function.
Germination energy and capacity of winter rye and winter triticale decreased along with the increase of the concentration of water extracts from dry and fresh matter of Apera spica-venti. The highest concentration of the tested extracts decreased the germination energy and capacity of both cereal species the strongest. Length of the first leaf and primary root at winter rye and winter triticale were significantly shorter on Petri dishes with higher extract concentration. Water extracts from fresh matter of Apera spica-venti stimulated the length of the first leaf of the studied cereals.

The sex structure of entomogamic, dioecious creeping thistle population was the object of the research conducted during three years in the western part of Kampinoski National Park. It contains: sex-ratio of specimens (shoots), sex-ratio of flowers in inflorescences (capitula) and spatial structure of sex in populations. Field studies were conducted on 3 spatial scales. The number of capitula on particular shoots in each sex, height of shoots and number of flowers in capitula were investigated too.
The analysis of concentrations of shoots shows that patches with female shoots are dominant. There are also more patches with the cover of female specimens over 50%. Sex-ratio of female shoots to male shoots is 2.5:1. The male shoots produce more capitula (average 27.2) than female ones (average 17.3). Female shoots are slightly higher than male ones (respectively 86.4 cm and 83.6 cm). The results concerning the ratio of flowers in capitula are difficult for interpretation because on each plot the results were different.

Studies were aimed at evaluating the dates of appearance and intensification of major developmental stages of barnyard grass plants sown into the fodder beet, spring wheat, and faba bean canopies with mechanical and herbicide weed control. The field experiments were conducted in 2000–2002 on specific silt soil developed from light loam. It was localized in Zakrzów within Tarnobrzeg city limits. Phenological observations consisted in recording the appearance date of the following barnyard grass phonologic stages in 10-day intervals starting from the sowing date: emergence, panicle formation, flowering, fruiting, and fruit shedding. In addition, during the crop plant harvest, fruiting and fruit shedding intensities were accompanied by the percentage values. Agrotechnology for the plant was typical. Objects with herbicides were treated using the following agents: fodder beet – Buracyl 80 WP (lenacyl 80%) at 1 kg.ha-1 rate, spring wheat – Chwastox Turbo 340 SL (MCPA 30% + dicamba 4%) at 2 l.ha-1 rate, and faba bean – Afalon 50 WP (linuron 50%) at 1.5 kg.ha-1 rate. For fodder beet and faba bean, herbicide were applied just after the sowing, while spring wheat was treated at full tillering stage. Herbicides were sprayed using field sprayer working under 0.25 MPa pressure.
It was revealed that the appearance date and the advancement of studied phenological stages of barnyard grass depended on crop plant species, type of weed control, as well as weather conditions during the study. Application of soil herbicides delayed barnyard grass emergence from 10 (fodder beet) to 20 days (faba bean). Herbicides decreased the number of shed plants in faba bean and spring wheat canopies, but they invoked opposite results in fodder beet.

The immediate and prolonged (i.e. two and three years after the treatment) effect of fertilizing with organic wastes on the content in tissues and consumption rate of potassium, calcium and manganese by Chenopodium album in various crops, in its varying contribution to the weed biomass was studied.
It was found that Chenopodium album share was differentiated in dependence on the combination of fertilization and the cultivated plant. The content of K, Ca and Mg in dry matter depended on the kind of fertilization (before beginning the experiment) and the cultivated plant. The amount of Chenopodium album biomass from each fertilized object most influenced the uptake of those macro elements from an area unit.

The study was carried out in 2003–2004 on the field which had been left fallowed for the last 3–4 years, on loess soil. Thirteen species of weeds were thoroughly analysed. The purpose of the analysis was assessing their prolificacy in relation to the selected biometric features. Each species was represented by 30 specimens. On the basis of each plant's seed numbers the average, minimal and maximal numbers of seeds for species were given in the table.
Among the most prolific were: Daucus carota, Conyza canadensis and Matricaria inodora, and the least prolific were Vicia grandiflora, Stachys palustris and Lithospermum arvense. Seed production of the studied weed species was significantly correlated with their air-dry weight and the number of fruits or fruit sets. Also, the correlation of seed production and the height of plants was found for Bromus secalinus, Viola arvensis, Stachys palustris, Centaurea cyanus and Vicia hirsuta. Among the discussed biometric features the weight of one thousand seeds and plant's height revealed slight deviation, while the number of fruits or fruit sets and air-dry weight – strong deviation from the average values.

Badania przeprowadzono w latach 2000–2002 na polu doświadczalnym należącym do Stacji Dydaktyczno-Badawczej Wydziału Biologiczno-Rolniczego Uniwersytetu Rzeszowskie-go. Badano wpływ zróżnicowanych dawek i sposobów stosowania azotu na wielkość, strukturę plonu i jakość ziarna pszenicy ozimej. Czynnikami doświadczenia były: A – odmiany pszenicy ozimej Begra i Kobra; B – poziomy nawożenia azotem doglebowo (saletra amonowa) i dolistne stosowanie mocznika. Plon ziarna obu odmian był uzależniony od dawki azotu, a przy poziomie nawożenia 120 kg · ha–1 również od sposobu jego stosowania. Badane odmiany pszenicy reagowały istotnym wzrostem plonu na zwiększenie dawki azotu w stosunku do kontroli. Dawka 120 kg N · ha–1 – 60 kg · ha–1 w formie sypkiej i 60 kg · ha–1 jako trzykrotny zabieg dokarmiania mocznikiem w porównaniu z dawką 120 kg N · ha–1 w całości aplikowaną w formie sypkiej spowodowała większy przyrost plonu ziarna obu odmian pszenicy i jego elementów składowych. Zwiększenie dawki azotu z 60 do 120 kg · ha–1 zwiększyło zawartość białka i potasu w ziarnie obu odmian, zmniejszyło natomiast zawartość fosforu, nie powodując jednocześnie zróżnicowania zawartości magnezu i wapnia. Sposób aplikacji azotu nie miał wpływu na zawartość białka i makroelementów w ziarnie pszenicy.

Published: April 2022

Kandelia candel, a mangrove belonging to the family Rhizophoraceae, the whole plant is reported to have anti-diabetic properties and was studied for the evaluation of in vitro antioxidant and antidiabetic study. Total Phenolic Content (TPC), Total Flavonoid Content (TFC) and Total Alkaloid Content were quantitatively estimated by using standard protocols. The study evaluated the antioxidant activity of the extract and the method was employed for the evaluation of antioxidant activity are DPPH radical scavenging assay, reducing power assay and Phosphomolybdenum assay. Potent antioxidant activities were shown by the acetonitrile extract and water extract of leaf and stem in all the assays. Acetonitrile extract of bark showing highest DPPH scavenging activity (IC50 = 31.84 g/ml). Plant extract showing poor, reducing power. The better reduction of molybdenum was shown by acetonitrile extract of bark followed by leaf (617.33 ± 4.44). Chloroform, acetonitrile and water extract of leaf and bark of Kandelia candel, were evaluated for antidiabetic activity by alpha-amylase inhibition assay, Water and acetonitrile extract show good inhibition. Highest TPC and TFC were obtained for the acetonitrile extract of bark (237.6 ± 1.06 and 1277.19 ± 3.41). These findings show that the polyphenolic constituents in the extracts are responsible for free radical scavenging capacity. The results of this study indicate that this plant is medicinal with prominent antioxidant activities.

Causes and Preventive Measures of Aggressive Behaviour among In-school Adolescents in Ilorin Metropolis: Stakeholders’ Perception
Authors: Badamas Omoshalewa Lasbat 
Published: April 2022

Aggressive behaviour has been described to be an act engaged in to harm someone who is considered to be vulnerable. It has been observed to be on the increase among young people, most particularly, adolescents in our society. This study therefore examines the stakeholders’ perceived causes and preventive measures of aggressive behaviours among in-school adolescents in Ilorin Metropolis in Nigeria. A descriptive survey design was used for this study. Two hundred senior secondary school students and 100 teachers; making a total of 300 respondents, were selected for the study. A questionnaire was used to obtain data from the respondents. The instrument was validated by experts in the Department of Social Sciences Education. Two research questions were answered and two research hypotheses tested. Percentage and mean ratings were used to answer Research Questions One and Two, while an independent t-test was used to test the two formulated hypotheses at 0.05 level of significance. The findings of this study revealed that the stakeholders’ perceived causes of aggressive behaviour among in-school adolescents in Ilorin Metropolis was poor teacher-students’ interactions. Stakeholders perceived preventive measures to aggressive behaviour to be regular moral and religion teachings, and parental monitoring of what their children watch on social media. Based on the discussion of findings and the conclusions drawn, it was recommended that aggressive behaviour among in-school adolescents can be prevented by engaging in moral and religion teachings on aggressive behaviour.
Theatre as an Exemption to the Economic Base
Authors: Gell Marissa 
Published: April 2022

Despite living in a capitalist society, theatre is still able to maintain a level of autonomy in the creation of its work. In this essay, I explore how Marx’s idea of base and superstructure, being the social framework of society, although relevant when examining the socio-political structures of our society does not allow for a deep understanding of theatre and capitalism. This is relevant in how some aspects of Marx’s superstructure are able to seem untouched by the economic mode of production. Despite theatre's reflection in different aspects of its production, it has been able to separate itself from the economic base by creating an art form that does not necessarily fit into Marx’s idea of a commodity. Thus, not allowing for traditional labour relations and commodity fetishism that results. Althusser's understanding, on the other hand, allows for a more autonomous structure, where theatre both reflects the economic base but also critiques it.
I use the example of Hamilton the musical to exemplify how features of this economic base can be present in a theatrical production. I also examine a local Edmonton retelling of Shakespeare's Titus Andronicus by Colleen Murphy called The Society for the Destitute Presents: Titus Bouffonius which uses techniques found in Brechtian style theatre. It is through these techniques that this theatre performance has been able to skirt the totality of economic production and provide a critique of the ideology present in society.

The Role of Forensic Medicine in Disclosing Premediated Killers (Study of Decision No. 116/Pid.B/2019/PN.Bms)
Authors: Fitri Aulia Ineke 
Published: April 2022

Forensic medical science is a science that is used for legal purposes by providing scientific evidence that can be used in solving crimes, especially the crime of murder. This science studies the cause of death, identification, state of post-mortem corpses. This study will discuss the role of forensic medicine in uncovering the crime of premeditated murder in case no. 116/Pid.B/2019/PN.Bms. The research method used is normative juridical, which is carried out through a literature study that examines secondary data in legislation and other legal documents, research results, assessment results, other references and is equipped with interviews. This study concludes that forensic medicine plays an essential role in investigating the crime of premeditated murder in case no. 116/Pid.B/2019/PN.Bms because of the need to identify corpses that have become bones and charred, so how important it is that forensic medicine is poured into evidence in the letter category in the form of Visum et Repertum, which by police investigators is under Article 133 of the Criminal Procedure Code to be used as legal evidence in uncovering and seeking the material truth of a criminal act that occurred. Suggestions in this study include providing education to the public regarding the treatment of evidence and the crime scene to change the disclosure of cases.

Published: April 2022

A personal shopper is an effort made by someone on personal social media and has become a trend among the public because of its ease. It is only necessary to hire someone traveling abroad and mention what goods they want will all get in hand without the hassle of going abroad. However, many of these businesses still commit fraud in practice, especially in terms of taxes. They tend to break down goods (splitting during customs checks to avoid taxes and import duties. This study aims to analyze import duties and taxes' imposition to import online personal shoppers and law enforcement efforts carried out by customs in dealing with personal shoppers who deliberately avoid taxes and import duties. This research uses normative juries research methods through literature by obtaining secondary data in legislation, research results, and scientific journals. Based on the research results, online personal shoppers' efforts are currently a rampant business in the community. This effort gives rise to the act of breaking up luggage or splitting done by an online personal shopper provider. Integrated law enforcement is required by involving relevant agencies and needs special arrangements about online personal shoppers.Keywords: Import duty, taxes, Personal shopper service business.
