Performance analysis of modified asymmetrically-clipped optical orthogonal frequency-division multiplexing systems

A modification to the Asymmetrically-Clipped Optical Orthogonal Frequency-Division Multiplexing (ACO-OFDM) technique is proposed through unipolar encoding. A performance analysis of the Bit Error Rate (BER) is developed and Monte Carlo simulations are carried out to verify the analysis. Results are compared to that of the corresponding ACO-OFDM system under the same bit energy and transmission rate; an improvement of 1 dB is obtained at a BER of 10-4. In addition, the performance of the proposed system in the presence of atmospheric turbulence is investigated using single-input multiple-output (SIMO) configuration and its performance under that environment is compared to that of ACO-OFDM. Energy improvements of 4 dB and 2.2 dB are obtained at a BER of 10-4 for SIMO systems of 1 and 2 photodetectors at the receiver for the case of strong turbulence, respectively

Design and Implementation of a 2.4 GHz Millimeter Wave Radar System for Soil Water Content Detection

Because water has the highest real permittivity value, close to 80, compared to dry soils\u27 real permittivity, which ranges from 3 to 15, measuring a soil\u27s permittivity is strongly reliant on its moisture content. Furthermore, increased relative permittivity leads to a larger reflectivity coefficient. According to these perspectives, adding water to dry soil generates notable changes in wet soil permittivity and modifies the reflectance and characteristics of incident electromagnetic waves (EMWs) at the soil-air interface. Thus, the soil water content (SWC) may be reliably determined by recording variations in the properties of incident EMWs compared to a reference dry soil case. This inspired us to develop a millimeter wave radar system to measure the SWC. In this paper, the design and hardware implementation of a 2.4 GHz millimeter wave radar system is introduced for SWC measurement. The SWC measurement principle of the proposed system is based on measuring the reflection coefficient of the soil-air interface. The received analog signal is amplified before it is converted into a digital signal that is sent by the Arduino microcontroller to the computer buffer via the serial communication port to be analyzed using the designed MATLAB code

Effect Of Various Sintering Protocols On The Translucency Of Highly Translucent Cubic Zirconia

Aim of the study: This study was carried out to evaluate the effect of various sintering protocols on the translucency of highly translucent cubic zirconia. Materials and methods: A total of forty discs of two types of zirconia ceramics were used in this study. The specimens were divided into two main groups according to the type of zirconia; Group 1 (n=20): Cubic zirconia (DD Cube X2 98color) and Group 2 (n=20): Tetragonal zirconia (BioZX2color). Each group was subdivided into two subgroups, where 10 discs were per subgroup according to the sintering protocol. Cubic and tetragonal zirconia blanks of dimensions (98 mm diameter × 25 mm thickness) were CAD/CAM milled into cylindrical-shaped blocks of dimensions (15 mm diameter × 25 mm thickness). Cylinders of both materials were cut with a diamond cutting saw into discs with larger dimensions (15 mm diameter × 1.2 mm thickness) to compensate for the approximately 23% shrinkage of the material during sintering, so as the final dimensions would be (12 mm diameter × 1 mm thickness). Discs were dried under a heating lamp and then conventionally and speed sintered according to the manufacturer\u27s instructions. The translucency of each subgroup was evaluated by measuring contrast ratio (CR) and translucency parameter (TP). Results: For both cubic or tetragonal zirconia, conventional sintering showed statistically significantly lower mean CR and higher mean TP than speed sintering (P-value \u3c0.001). Conclusion: Different sintering protocols showed a significant effect on the translucency of cubic and tetragonal zirconia

KIRURŠKO LIJEČENJE STRES URINARNE INKONTINENCIJE, FEKALNE INKONTINENCIJE I VAGINALNOG PROLAPSA NOVOM OPERACIJOM »URETRO-ANO-VAGINOPLASTIKA«

We put forward a novel concept explaining the mechanism of micturition and the factors that control urinary continence. Also, we describe the mechanism of defecation and the factors that control stool continence and prevent fecal incontinence. A weak internal urethral sphincter (IUS) will not withstand sudden rise of intra-abdominal pressure and urine will leak. The weakness of the IUS is mostly due to traumatic rupture of its wall as a result of the huge vaginal distension that happens during prolonged, difficult and multiple frequent labors. So, surgical correction is by exposing that rupture and mending its walls. Also the marked vaginal distension which occurs in labor will cause lacerations in the internal anal sphincter (IAS) which is intimately related to the posterior vaginal wall. The torn weak IAS will cause fecal incontinence (FI). Exposing the torn IAS and mending the torn walls will restore the sphincter strength and fecal continence. Vaginal prolapse occurs as a result of vaginal wall weakness, redundancy and flabbiness subsequent to its marked stretching of its walls during vaginal deliveries. Overlapping the vaginal flaps both in the anterior and posterior vaginal wall, such repair will strengthen the vaginal walls, as if we put a collagenous mesh but instead this is an autologus collagenous mesh. We innovated an operation called »urethro-ano-vagino-plasty« to surgically treat urinary incontinence, fecal incontinence and and vaginal prolapse. Objectives. To describe this novel operation, and assess its results for a follow up period of 24 months. Methods. 134 patients with SUI and FI were assessed. Urethro-ano-vaginoplasty was done, and the results were assessed immediately and for 24 months follow up. Results. 121 (90.3%) gained urinary and fecal continence and remained continent in the follow up period. Conclusion. The internal anal sphincter (IAS) is a collageno-muscular tissue cylinder that surrounds the anal canal innervated by alpha-sympathetic nerve supply from the hypogastric nerves. It is surrounded in its lower part by the EAS which is a striated muscle innervated by the pudendal nerve. Its damage during childbirth causes fecal incontinence and mending the torn walls restores fecal continence.Predstavljena je nova koncepcija o mehanizmu mokrenja i čimbenicima koji reguliraju mokraćnu kontinenciju. Također, opisan je mehanizam defekacije te čimbenici koji kontroliraju kontinenciju stolice i sprječavaju fekalnu inkontinenciju. Slab unutarnji uretralni sfinkter (IUS) se ne može suprostaviti naglom porastu intraabdominalnog tlaka te će mokraća bježati. Slabost IUS-a je većinom posljedica ozljede njegove stijenke zbog silnog vaginalna širenja koje se zbiva tijekom produljenih, tešlih i učestalih rađanja. Kirurška korekcija se sastoji u nalaženju prsnuća i opskrbi njegove stijenke. Vaginalno širenje tijekom poroda uzrokuje prsnuće unutarnjeg analnog sfinktera (IAS), koji je intimno povezan sa stražnjom vaginalnom stijenkom. Oslabljeni i prsnuti IAS uzrokuje fekalnu inkontinenciju (FI). Prikaz prsnutog IAS-a i šivanje njegovih razderanih stijenki uspostavit će snagu sfinktera i fekalnu kontinenciju. Vaginalni prolaps nastaje kao posljedica slabosti i mlohavosti vaginalne stijenke te njene proširenosti, zbog istezanja tijekom vaginalnog rađanja. Preklapanjem vaginalnih režanja prednje i stražnje stijenke ojačava se stijenka, umjesto umjetne mrežice postavljamo vlastitu autolognu kolagenu mrežicu. Izumjeli smo za korekciju urinarne i fekalne inkontinencije te vaginalna prolapsa novu operaciju i nazcvali je »uretro-ano-vagino-plastika«. Cilj rada je opisati novu operaciju i prosuditi njen uspjeh nakon 24 mjeseca. Metoda. Operirane su 134 bolesnice sa stres urinarnom inkontinencijom i fekalnom inkontinencijom. Rezultati. 121 bolesnica (90,3%) je opet postigla mokraćnu i fekalnu kontinenciju i zadržala ih tijekom praćenja. Zaključak. Unutarnji analni sfinkter je kolegano-mišićni tkivni cilindar, inerviran alfa-simpatičnim živcima iz hipogastričkog pleksusa koji okružuje analni kanal. U donjem dijelu je okružen vanjskim sfinkterom koji je poprečno-prugaste mišićne građe i inerviran ograncima pudendalnog živca. Njegovo oštećenje tijekom rađanja uzrokuje fekalnu inkontinenciju, a šivanje prsnute stijenke uspostavlja fekalnu kontinenciju

A newly developed strain of Enterococcus faecium isolated from fresh dairy products to be used as a probiotic in lactating Holstein cows

The objective of this study was to determine the ability of an isolated strain (EGY_NRC1) or commercial (NCIMB 11181) Enterococcus faecium as a probiotic for lactating cows. Two experiments were conducted: In Experiment 1, the effects of three levels (1, 2, and 3 g/kg diet, DM basis) of isolated and commercial E. faecium on in vitro ruminal fermentation kinetics, gas, methane (CH4) and nutrient degradability were determined. In Experiment 2, thirty multiparous Holstein cows (633 ± 25.4 kg body weight) with 7 days in milk, were randomly assigned to 3 treatments in a completely randomized design in a 60-day experiment. Cows were fed without any additives (control treatment) or supplemented with 2 g/kg feed daily of E. faecium EGY_NRC1 (contain 1.1 × 109 CFU/g) or commercial E. faecium NCIMB 11181 (contain 2 × 1012 CFU/g). Diets were prepared to meet cow's nutrient requirements according to NRC recommendations. Probiotic doses were based on the in vitro Experiment 1. Feed intake, digestibility, blood parameters and lactation performance were evaluated. In Experiment 1, the isolated E. faecium linearly and quadratically increased (P < 0.001) in vitro total gas production (TGP), the degradability of dry matter (dDM) and organic matter (dOM) while decreased (P < 0.05) methane (CH4) percent of TGP, NH3CH4 production, and pH. The commercial E. faecium increased TGP and decreased (P < 0.01) CH4 production, pH and increased the dDM and dOM, short chain fatty acids and ruminal NH3-N concentration. In Experiment 2, the isolated E. faecium increased (P < 0.01) total tract digestibility of DM, neutral and acid detergent fiber, daily milk production and feed efficiency compared to the control treatment without affecting feed intake and milk composition. Moreover, the isolated E. faecium increased (P < 0.05) the proportion of C18:1 trans-9, C18:2 cis-9-12 and C18:2 trans-10 cis-12. Both isolated and commercial E. faecium improved (P < 0.01) organic matter, crude protein and nonstructural carbohydrates digestibility, increased serum glucose (P = 0.002) and decreased serum cholesterol (P = 0.002). Additionally, both E. faecium strains decreased C23:0 (P = 0.005) in milk. In conclusion, the use of E. faecium (isolated and commercial) at 2 g/kg DM of feed improved feed efficiency and production performance, with superior effects on animal performance from isolated E. faecium compared to the commercial one

Cancer Incidence in Egypt: Results of the National Population-Based Cancer Registry Program

Background. This paper aims to present cancer incidence rates at national and regional level of Egypt, based upon results of National Cancer Registry Program (NCRP). Methods. NCRP stratified Egypt into 3 geographical strata: lower, middle, and upper. One governorate represented each region. Abstractors collected data from medical records of cancer centers, national tertiary care institutions, Health Insurance Organization, Government-Subsidized Treatment Program, and death records. Data entry was online. Incidence rates were calculated at a regional and a national level. Future projection up to 2050 was also calculated. Results. Age-standardized incidence rates per 100,000 were 166.6 (both sexes), 175.9 (males), and 157.0 (females). Commonest sites were liver (23.8%), breast (15.4%), and bladder (6.9%) (both sexes): liver (33.6%) and bladder (10.7%) among men, and breast (32.0%) and liver (13.5%) among women. By 2050, a 3-fold increase in incident cancer relative to 2013 was estimated. Conclusion. These data are the only available cancer rates at national and regional levels of Egypt. The pattern of cancer indicated the increased burden of liver cancer. Breast cancer occupied the second rank. Study of rates of individual sites of cancer might help in giving clues for preventive programs

FEKALNA INKONTINENCIJA Nova koncepcija: Uloga unutarnjeg analnog sfinktera pri defekaciji i fekalnoj inkontinenciji

Introduction. Fecal incontinence is involuntary escape of stool, mucus and/or flatus.Its causes are: anal sphincter damage (childbirth trauma, surgical trauma.); constipation; diarrhea; rectocele; rectal prolapse and rarely congenital causes. Fecal material entering the rectum is evacuated by defecation during which: 1. The smooth muscles of the distal colon and rectum contract, propelling the feces into the anal canal; 2.The anal sphincter relaxes allowing defecation to occur. We put forward a recent concept on the patho-physiology of defecation.The mechanism of defecation has two stages: first stage: (in early childhood) before training; second stage is after training. The mother starts to teach her child how to control himself. This is gained by maintaining high alpha sympathetic tone at the internal anal sphincter (IAS) keeping it closed all the time till appropriate place and time are available. Wherever appropriate place is available and there is a desire, six neuromuscular actions will occur: 1) the person will lower the acquired high alpha sympathetic tone at the IAS relaxing it opening the anal canal; 2) through the voluntary nervous system (NS) he will widen the ano-rectal angle to bring the anal canal and the rectum on one axis. This is done through the pelvic floor muscles; 3) through, voluntary NS he will also relax the external anal sphincter (EAS); then synergistic actions between the voluntary and autonomic nervous system occur; 4) the abdominal and diaphragmatic muscles contract, increasing the intra- abdominal pressure and forcing the feces through the anal canal (via the voluntary NS); 5) the smooth muscles of the distal colon and rectum contract, propelling the feces into the anal canal (through the autonomic NS); 6) followed by sequential contractions of the three parts of the EAS (deep then superficial and then the subcutaneous parts) that will squeeze the anal canal propelling any residual contents. Objectives. Imaging of the anal canal by 3-dimension ultrasound (3DUS) in normal women and women suffering from fecal incontinence and from rectocele, to compare the state of the IAS and EAS. Methods. 40 patients with FI were assessed clinically and by imaging using 3DUS, and also 10 normal women not suffering from fecal incontinence (FI) as a control. Results. The anal canal is closed in normal women, with intact IAS. In women suffering from FI the anal canal is wide and open with torn IAS. Conclusion. The internal anal sphincter (IAS) is a collageno-muscular tissue cylinder that surrounds the anal canal innervated by alpha-sympathetic nerve supply from the hypogastric nerves. It is surrounded in its lower part by the EAS which is a striated muscle innervated by the pudendal nerve. Its damage during childbirth causes fecal incontinence, and mending its torn wall restores fecal continence.Uvod. Fekalna inkontinencija (insuficijencija stolice) znači nevoljno bježanje stolice, sluzi i/ili vjetrova. Uzroci su: oštećenje sfinktera (pri rađanju djeteta, kirurška trauma), zatvor stolice, proljev; rektokela, ispadanje rektuma, rijetko prirođeno ispadanje. Stolica ulazi u završno crijevo te iz njega izlazi na sljedeći način: 1. Glatki mišići donjeg i završnog dijela debelog crijeva se stežu, potiskujući feces u analni kanal; 2. Analni sfinkter olabavi i omogući da uslijedi defekacija. Predstavljamo svježe shvaćanje o patofiziologiji defekacije. Mehanizam ima dva razdobkja: prvo razdoblje je rano djetinstvo, bez poduke; drugo razdoblje je nakon poduke. Majka podučava svoje dijete kako se kontrolirati. To se postiže visokim alfa simpatičkim tonusom unutarnjeg analnog sfinktera, držeći ga zatvorenim sve dok se ne ukaže odgovarajuće mjesto i vrijeme. Kad se nađe odgovarajuće mjesto, i ako postoji želja, počinje šest sinergističkih neuromuskularnih aktivnosti: 1) osoba će sniziti postojeći visoki alfa simpatički tonus unutarnjeg analnoga sfinktera i time otvoriti analni kanal; 2) pomoću voljnog živčanog sustava smanjit će ano-rektalni kut i dovesti ih u istu osovinu; to postiže pomoću mišića dna zdjelice: 3) voljnim živčanim sustavom također će omlohaviti vanjski analni sfinkter; tada nastupa sinergistična djelatnost voljnog i autonomnog živčevlja; 4) trbušni i dijafragmalni mišići se stežu, povećavaju intraabdominalni tlak te potiskuju feces kroz analni kanal; 5) stežu se glatki mišići debelog crijeva i rektuma te potiskuju feces u analni kanal (autonomnim živčevljem); 6) slijede segmentalna stezanja sva tri dijela vanjskog sfinktera (dubokog, površnog pa potkožnog), koja će iz analnog kanala istisnuti sve zaostatke. Svrha rada. Trodimenzionalnim ultrazvukom prikazati analni kanal u zdravih žena te u onih koje pate od fekalne inkontinencije i rektokele, usporediti njihov unutrašnji i vanjski analni sfinkter. Metode. Analizirano je klinički i 3DUZ-om 40 pacijentica s fekalnom inkompetencijom i uspoređeno s 10 zdravih žena. Rezultat. Analni kanal je u zdravih žena zatvoren, njihov unutrapnji sfinkter je neoštećen. U žena s fekalnom inkompetencijom analni kanal je širok i otvoren te s razderanim sfinkterom. Zaključak. Unutarnji analni sfinkter je kolageno-mišićno tkivo oblika cilindra koje okružuje analni kanal, inerviran je alfa-simpatičkim živcima iz hipogastričkog pleksusa. Unutarnji sfinkter je okružen donjim dijelom vanjskog analnog sfinktera, koji je građen od prugastog mišićja inerviranog pudendalnim živcem. Njegovo oštećenje tijekom rađanja uzrokuje fekalnu inkontinenciju. Prepravak njegove razderane stijenke uspostavlja fekalnu kontinenciju

Genus Salsola : chemistry, biological activities and future prospective-a review

The genus Salsola L. (Russian thistle, Saltwort) includes halophyte plants and is considered one of the largest genera in the family Amaranthaceae. The genus involves annual semi-dwarf to dwarf shrubs and woody tree. The genus Salsola is frequently overlooked, and few people are aware of its significance. The majority of studies focus on pollen morphology and species identification. Salsola has had little research on its phytochemical makeup or biological effects. Therefore, we present this review to cover all aspects of genus Salsola, including taxonomy, distribution, differences in the chemical constituents and representative examples of isolated compounds produced by various species of genus Salsola and in relation to their several reported biological activities for use in folk medicine worldwide
