The concentration and form of some metals and metalloids in soil is governed by many chemical and physical properties of soil as pH, redox, Fe, Al ions and soil composition. The paper studied presents influence of chemical soil properties, environment conditions and selenium fertilization rate applied on ions status of zinc, cadmium, selenium and iron in soil and plant material, as well as specific adsorption of these ions in two different maize hybrids. The study was conducted at the farm Vita-Vi Višići (Čapljina). The experiment design was a completely randomized design with two hybrids, four different fertilization treatments in four replications. The experimental area was implemented standard agricultural management practices of preparation, tillage, fertilization, application of protective agents. Hybrid NP Pako is selected in order to achieve a high yield, and M34 hybrid for quality yield. The test results and statistical analysis revealed no significant difference in the yield of hybrids combined with different fertilization treatments. Accumulation of selenium, zinc, cadmium and iron in upper ground plant part of maize was not affected by fertilization treatments or selected hybrid. The highest yield was achieved by hybrid M34 Pioneer of 37.6 t ha- 1and the highest yield was obtained in application of third fertilization treatment 20 kg NaSeO4ha-1, but without statistically significant differences comparing to other hybrid or applied treatments. The highest content of selenium in the plant was found in hybrid NP PAKO 0.06 mg Se kg-1 of dry matter of maize applying the fourth liquid fertilization treatment (20 kg Na2SeO4ha-1) but also without statistically significant difference comparing to other hybrid or fertilization treatment. Content of zinc, cadmium and iron in soil or plant material had not shown significant differences due to the applied fertilization or used maize hybrids, but some fluctuations were observed. Selenium fertilization did not have a limiting effect on the formation of the yield and tested elements, but its mobility and availability in soil and plant depends also on other factors as soil properties and climatic conditions of growing season.

At livestock farms most part of nitrogen arrives as purchased products (fertilizer, animal feed and purchased animals). Within the boundaries of the farm, nitrogen recycles between the livestock and crop components. Finally, nitrogen exit a livestock operation unit preferably as managed outputs (meat, crops and manure) sold off the farm. Difference between the inputs and the managed outputs represents an itrogen balance that can be an indicator of environmentally sustainable production. Nitrogen (im)balance consider only amount of the nutrient that cross the border of the farm. In ideal conditions the nitrogen input/output ratio should be 1:1. Some nitrogen exits the farm as losses to the environment (nitrates in groundwater, ammonia volatilized into the atmosphere, and nitrogen into groundwater and surface water).
A study was conducted on five small poultry farm in order to determine whole farm nitrogen balance as difference between total nitrogen inputs (one day chickens, litter, animal feed) and outputs (meat, dead animals and manure). Selected farms differ according to capacity (ranging from 5,000 to 40,000 birds), producers of poultry feed, type and length of manure storage as well as other sensible farming practice which could influence on nitrogen balance.
Collection of data on all farms is done using a questionnaire. Nitrogen content in all substrates (feed, manure, litter) was determinate by Kjeldahl procedure. The results of the whole farm nitrogen balance with the recommendations of its balancing in order to reduce the negative environmental implications are presented in the paper.

The research objective was to determine the influence of basic soil chemical properties on total concentration and available fractions of essential trace elements in the soil. Agrochemical soil analysis were conducted at two localities of different soil properties Berak and Vinogradci in eastern Croatia. The soil at the site Berak was eutric cambisol of neutral reaction (pH average (H2O) 7.20), while the soil in Vinogradci was luvisol of slightly acid reaction (average pH (H2O) 5.87). Both soils were poor in organic matter and well supplied with phosphorus and potassium. As expected, at both analyzed sites the highest average concentrations were determined for total Fe, Mn and Zn followed, and the lowest concentrations were for total Cu. Higher total concentrations of analyzed microelements were recorded at the Berak site. The total concentrations of Zn and Cu in all analyzed soil samples were below the maximum permissible concentrations. The highest average concentration of available microelements fraction by EDTA Extraction, were at the Berak site determined for Mn (50.52 mg/kg), then Fe (21.77 mg/kg), Cu (4.78 mg/kg), and the lowest for Zn (1.47 mg/kg). At the Vinogradci site average concentrations of available fraction of microelements determined by EDTA extraction were the highest for Fe (77.09 mg/kg), then Mn (30.75 mg/kg), Cu (4.36 mg/kg), and the lowest for Zn (1.76 mg/kg). Identical order of average concentrations at both sites was also recorded for extraction with DTPA solution. Comparing available fraction of microelements by localities, higher average concentrations of Mn and Cu were found at the site Berak, while on site Vinogradci higher average concentrations were of Fe and Zn. At both sites the DTPA method extracted more of Fe and Mn, an average of 51.06% and 6.39% more than the EDTA method, but the method EDTA extracted more Zn and Cu, an average of 127.10% and 100.40% than DTPA method. The smallest share of the available fraction of the total concentration was recorded for Fe (0.06% by EDTA -0.09% by DTPA ), followed by Zn (1.20% by DTPA - 2.74% by EDTA) and Mn (5.93% by EDTA – 6.31% by DTPA), while the largest share was observed for Cu (10.92% by DTPA and 21.84% by EDTA).
Kedudukan Keteapan MPR Pasca Amandemen Konstitusi

Published: February 2022

Abstract
After the amendment of UUD 1945, MPR is no longerthe highest state institution in Indonesia. This change had an effect on the function of the MPR. MPR just like a joint forum between the DPR and DPD. Amendments of UUD 1945 produce Institutions in horizontal functional relations, not in vertical structural relationships. This certainly has an impact on the legal products issued by the MPR, namely the TAP MPR. Then the legal products that can be outlined in the TAP MPR are only determination (beschikking), for example the determination of someone elected to be President and/or Vice President. Therefore the MPR regulation which is regulating as in the past will nolonger exist. But on the other hand the re-inclusion of the TAP MPR in the hierarchy of laws will lead to new problems, how to purpose judisial review ofTAP MPR if it contradicts with the UUD 1945, while the authority of the Constitutional Court is limited to testing the Law to the Constitution. And till nowthere are not specific provisions to solve that. One way that can be doing is through legislative review conducted by that institution.

Abstrak
Pasca diamandemennya Undang Undang Dasar Tahun 1945, MPR tidak lagi menjadi lembaga tertinggi Negara. Perubahan ini membawa akibat pada fungsi MPR yang menjadi sebuah forum gabungan join session antara DPR dan DPD. Amandemen UUD 1945 menghasilkan Lembaga Negara dalam hubungan funsional yang horizontal, bukan dalam hubungan structural vertical. Hal ini tentu berdampak kepada produk hukum yang dikeluarkan oleh MPR, yakni Ketetapan MPR. Maka produk hukum yang dapat dituangkan dalam ketetapan MPR hanyan keputusan yang bersifat penetapan (beschikking) saja misalnya penetapan seseorang terpilih menjadi Presiden dan/atau Wakil Presiden. Dengan demikian Ketetapan MPR yang bersifat mengatur (regiling) seperti di masa lalu tidak aka ada lagi. Namun disisi lain kembali dimasukkannya TAP MPR dalam hirarki peraturan perundang undangan akan menimbulkan permasalahan baru, yakni bagaimana melakukan pengujian materi terhadap TAP MPR jika bertentangan dengan UUD 1945, sedangkan wewenang Mahkamah Konstitusi hanya terbatas sampai pada pengujian Undang Undang terhadap UUD. Dan sampai saat ini belum ada ketentuan khusus baik di tingkat UUD maupun Undang Undang lainnya yang menerangkan tentang pengujian materi terhadap TAP MPR. Salah satu cara yang dapat dilakukan yaitu melalui legislative review yang dilakukan lembaga itu sendiri dengan cara dibatalkan atau diubah melalui TAP MPR juga.

Published: February 2022

Background: Pulmonary Embolism (PE) is the third highest cause of death in cardiovascular. Right ventricular failure usually occurs within the first few hours, leading to the occurrence of right ventricular dysfunction (RVD). Computed tomography pulmonary angiography (CTPA) is an imaging technique that is the gold standard in evaluating patients with suspected PE because of their high sensitivity and specificity. The presentation of Pulmonary CTA images in PE needs to be interpreted correctly so that there is no loss of diagnosis by radiologists and cardiologists. This article aims to find out how to minimize the presence of mispreseption in findings of PE cases using CT-Scan modalities with the CT Pulmonary Angiography protocol.
Methods: The type of research in this mini research is qualitative research with an experimental approach with measurements on the pulmonary arteries that have emboli, which are aimed at knowing the type and evaluating existing parameters to reduce misdiagnosis in PE patients.
Results: The results of identifying the type of emboli using ROI (Region Of Interestand) measurements of the right and left ventricles can be seen that the patient has acute pulmonary embolism. Precise parameter settings play a role in producing informative diagnostic images of Pulmonary CTA.
Conclusion: To obtain informative diagnostic images in cases of pulmonary embolism, it is necessary to pay attention in optimizing the procedures and parameters of pulmonary Angiography CT so that there is no misdiagnosis in patients.
