Comparison between P&O and SSO techniques based MPPT algorithm for photovoltaic systems

Solar photovoltaic (SPV) systems are a renewable source of energy that are environmentally friendly and recyclable nature. When the solar panel is connected directly to the load, the power delivered to the load is not the optimal power. It is therefore important to obtain maximum power from SPV systems for enhancing efficiency. Various maximum power point tracking (MPPT) techniques of SPV systems were proposed. Traditional MPPT techniques are commonly limited to uniform weather conditions. This paper presents a study of MPPT for photovoltaic (PV) systems. The study includes a discussion of different MPPT techniques and performs comparison for the performance of the two MPPT techniques, the P&O algorithm, and salp swarm optimization (SSO) algorithm. MATLAB simulations are performed under step changes in irradiation. The results of SSO show that the search time of maximum power point (MPP) is significantly decreased and the MPP is obtained in the shortest time with high accuracy and minimum oscillations in the generated power when compared with P&O

SITUATION OF BRUCELLOSIS IN CATTLE FARMS IN A PASTORAL REGION OF ALGERIA (DJELFA) AND ITS IMPACT ON PUBLIC HEALTH: AN EXAMPLE OF DETECTION OF BRUCELLA ORGANISM IN FERMENTED RAW COW MILK « L’BEN »

Brucellosis is an infectious disease that spreads to humans and causes major economic loss. In addition, it poses a public health problem in Algeria and in many countries. In order to assess the situation of this disease in the region of Djelfa (Algeria) and to estimate its risk on public health, a study was extended from 2010 to 2018. In addition, it is accompanied by bacteriological analyzes on samples of "L’ben" fermented milk taken from certain outlets in the same region to find out the importance of brucellosis, as an infectious disease, as well as the risks to the health of consumers . The results showed that out of a total of 287640 cattle, only 4.42% were screened with a reported prevalence of seropositive cattle of 2.51%. In addition, the prevalence of bovine brucellosis varied from year to year. It was low in 2010 with 07 reported cases (0.67%), while it was high in 2016 with 57 reported cases (4.18%). In addition, for human brucellosis, the prevalence varies between 4.3% in 2013 and 20.25% in 2018, with an average of 11.11%. In parallel, the results of laboratory analysis have shown that the average prevalence rate of brucella spp in fermented milk "L’ben" was 77.78% and that the highest rate was observed in Messaad (100%) and Hassi Bahbah (100%). While the lowest rate was reported in Dar Chioukh (33.33%). These results reflect the risk posed to cattle by brucellosis, especially on public health, and the risk posed by the consumption of  brucellosis-contaminated L’ben. This necessitates the implementation of a disease control and awareness program in order to avoid various accidents and significant economic losses. In addition, the early diagnosis of the disease helps preserve the health of the consumer thereafter

Formation of one-dimensional self-assembled silicon nanoribbons on Au(110)-(2x1)

We report results on the self-assembly of silicon nanoribbons on the (2x1) reconstructed Au(110) surface under ultra-high vacuum conditions. Upon adsorption of 0.2 monolayer (ML) of silicon the (2x1) reconstruction of Au(110) is replaced by an ordered surface alloy. Above this coverage a new superstructure is revealed by low electron energy diffraction (LEED) which becomes sharper at 0.3 Si ML. This superstructure corresponds to Si nanoribbons all oriented along the [-110] direction as revealed by LEED and scanning tunneling microscopy (STM). STM and high-resolution photoemission spectroscopy indicate that the nanoribbons are flat and predominantly 1.6 nm wide. In addition the silicon atoms show signatures of two chemical environments corresponding to the edge and center of the ribbons.Comment: Under publication in Applied Physics Letter

Boriding and boronitrocarburising effects on hardness,wear and corrosion behavior of AISI 4130 steel

The effects of boriding and boronitrocarburising surface treatments on the microstructure and mechanicalproperties of AISI 4130 steel have been investigated. Pack boriding was carried out at 1223 K for 5 h and 8h, while the double treatment of boronitrocarburising consisted of salt bath nitrocarburising at 853 K for 6 hfollowed by pack boriding at the same temperature and times as the boriding treatment. Microstructure examinationof the borided and boronitrocarburised layers was carried out using optical and scanning electronmicroscopy, and phase identification was obtained using X-ray diffraction. Vickers hardness, wear and corrosionweight loss tests were used to evaluate the mechanical properties and corrosion behaviour. The results ofX-ray diffraction analysis revealed the presence of superhard phases such as FeB, Fe2B, CrB, MnB andMnB2, indicating that pack boriding surface treatment conducted at 1223 K for 8 h exhibited the highesthardness, low coefficient of friction and the greatest wear resistance. Boronitrocarburising treatment, on theother hand, caused a reduction in both the depth of iron borides zone and mechanical properties compared tothe boriding surface treatment. These recommended treatments offer to industrialists a particular contributionand interest in the development of these steels, which can be applied in various fields.Keywords: AISI 4130, Boriding, Boronitrocarburising, Microstructure, Mechanical properties

Safety and efficacy of percutaneous nephrolithotripsy in comorbid patients: A 3 years prospective observational study

Purpose: To report the result of percutaneous nephrolithotripsy (PCNL) via standard nephrostomy tract in a single training institution. The perioperative complications in relation to the comorbid state are particularly assessed. Patients and methods: A prospective interventional study between January 2019 to November 2022, included 210 patients scheduled for PCNL. The average age was 40.3 ± 11.8 years (range 18- 67 years). Patients were categorized into two groups. The first group comprised 146 cases (69 .5%) with no associated co-morbidities while the second group 64 (30.5%) had co-morbidities such as obesity in 4 cases (1.9%), hypertension (HTN) in 24 cases (11.4%) cases, diabetes mellitus (DM) in 17 (8.1%) cases, history of recurrent stone surgery in 11 (5.2%) cases and more than one in 8 cases (3.8%). Co-morbidities, stone burden, location of stone, time of surgery, stay in the hospital, further operations, and negative events were among the reported data. Complications and the stone-free rate were the main outcome indicators. Results: Intraoperative complications were reported in 40 (18.8%) patients (18 group 1 and 22 group 2) during PCNL. Bleeding occurred in 22 (10.5%) patients (9 group 1 and 13 group 2), blood transfusions were needed in 4 (1.9%) (2 group 1 and 2 group 2), extravasation was observed in 11 patients (5.2%) (6 group 1 and 5 group 2) and cardiac arrhythmia in 3 (1.4%) (1 group 1 and 2 group 2) patients. Postoperative complications occurred in 61 patients (29%) (24 group 1 and 37 group 2) in the form of fever in 10 patients (4.8 %) (3 group 1 and 7 group 2) and prolonged leakage in 50 patients (23.8%) (21 group 1 and 29 group 2). One patient of group 2 died from postoperative sepsis. Extravasation and postoperative leakage were higher in diabetic patients than in non-diabetics. Stonefree rate was 60.5% (127 of 210). Clinically significant residual fragments (CSRFs) found in 70 cases (33.3%) (33 group 1 and 37 group 2). In 13 cases (6.2%) (5 group 1 and 8 group 2), clinically insignificant residual fragments (CIRFs) were found. In 8 (3 group 1 and 5 group 2) of the 13 cases, spontaneous stone passage was observed within 4-6 weeks of surgery. Residual stones in three cases (1 group 1 and 2 group 2) were asymptomatic and 4 mm or less, whereas stones increased in two cases of group 2. Among all factors studied, stone burden was significantly correlated to both intraoperative and postoperative complications. The occurrence of postoperative fever increased with large stone burden. Conclusions: PCNL is a therapeutic modality that is effective, feasible, and safe for a wide range of patients with concurrent medical issues. A steep curve is required to reduce intraoperative and postoperative complications
